Presentation
The study “Gender Discrimination and Economic Outcomes in Chile” is an ambitious
attempt at providing systematic evidence for an area of great interest.
This project is comprised of three studies that the Centro de Microdatos of the Department
of Economics of the Universidad de Chile is developing in parallel. This final report presents
the final papers in its three components.
Firstly, the chapter “An Experimental Study about Labor Market Discrimination: Gender,
Social Class and Neighborhood” is presented. This paper examines whether there are
differences in the response rate for curriculum vitae sent in response to job vacancies
published in the main newspaper of Chile, both for gender and socioeconomic
characteristics. In the version of the article presented, results are obtained for 3,500 CVs
sent.
Secondly, the study “Is there labor market discrimination among professionals in Chile?
Lawyers, Doctors and Business-people” is presented. This paper is done based on a survey
colleted specially for these effects. It is the first database of professionals in Chile containing
data on non-cognitive abilities, real labor market history, social and family background and
others. The aim is to investigate whether taking into account many variables that in generally
are unobservable we still have differences in wages to only to gender.
Finally, the third chapter of this project includes is called “Ability, Schooling Choices and
Gender Labor Market Discrimination: Evidence for Chile”. This paper studies the
importance of schooling decisions and abilities in explaining gender gaps in wages. In the
analysis we use a rich data set for Chile (the Social Protection Survey). This data set contains
information not only on labor market outcomes but also on schooling attainment and
schooling performance. We introduce an empirical model in which agents make schooling
and labor market choices based on this unobserved ability (in addition to observables). We
use schooling performance to identify the distribution of unobserved abilities in the
population.

Chapter 1
“An Experimental Study about Labor Market Discrimination: Gender, Social Class
and Neighborhood”
Abstract
The objective of this chapter is to study the Chilean labor market and determine the presence or absence of
gender discrimination. In order to break past the limitations of earlier works, an experimental design is used,
the first of its kind in Chile. This study also allows socioeconomic discrimination associated to names and
places of residence in the Chilean labor market to be tackled.
The study consists of sending fictitious Curriculum Vitae for real job vacancies published weekly in the “El
Mercurio” newspaper of Santiago. A range of strictly equivalent CVs in terms of qualifications and employment
experience of applicants are sent out, only varying in gender, name and surname, and place of residence. The
study allows differences in call response rates to be measured for the various demographic groups. In the
version of the article presented, results are obtained for 6,300 CVs sent.
Our results show no significant differences in callback rates across groups, in contrast with what is found in
other international studies.

Introduction
Gender and social discrimination in the labor market are some of the key issues in the
discussion on public policies in Latin America. However, empirical evidence and academic
research on the matter have been rather scarce until now. This is also the case in Chile.
No matter how much has been done to study labor market discrimination, either racial,
ethnic or gender, the issue of detection is still unsettled. In the usual regression analyses
there are several problems of unobservable variables that clearly bias the results (Altonji and
Blank, 1999; Neal and Johnson, 1996) and, on the other hand, experimental studies have
been under discussion for not correctly measuring discrimination (Heckman and Siegelman,
1993; Heckman, 1998).
In Chile, despite the fact that the average years of schooling of Chilean female workers are
not statistically different from those of male workers, average wages of male workers are
25% higher 1 . In fact, previous studies 2 suggest that gender discrimination is a factor in
determining wages in the Chilean labor market. Estimates of the Blinder-Oaxaca
decomposition give “residual discrimination” a significant participation in the total wage
gap 3 . The evidence also shows stable and systematic differences in the returns to education
and to experience by gender along the conditional wage distribution. Additionally, it has
been shown that “residual discrimination” is higher for women with more education and
experience.
Furthermore, Chilean female labor force participation is particularly low, 38.1% compared to
44.7% in Latin America 4 . This is even lower for married women and in fact, higher
participation is found in separated or divorced women (Bravo, 2005). This latter fact may be
interpreted as evidence of female preferences for non-market activities 5 .
However, this “residual discrimination” is only a measure of how much of the wage gap is
due to unobservable factors. Therefore, these measures of discrimination are biased due to
the lack of relevant controls. A recent study on discrimination by social class in Chile (Núñez
1 Own calculations using CASEN 2003. Once you correct for human capital differences and occupational
choice this gap falls to 19% approximately.
2 Previous studies for Chile are Bravo (2005); Montenegro (1998); Montenegro and Paredes (1999) and Paredes
and Riveros (1994).
3 Bravo (2005) shows that taking all employed workers and after controlling for years of schooling and
occupation, the wage gap was 13.5% in 2000. Using the Blinder-Oaxaca decomposition he concludes that most
of this difference was due to “residual discrimination”.

5 Contreras and Plaza (2004) also found that there are cultural factors, such as sexism, that significantly
influence female labor force participation in Chile.

and Gutiérrez, 2004) uses a dataset which reduces the role of unobserved heterogeneity
across individuals, but it has several limitations 6 . Furthermore, there are no attempts at
studying discrimination using neither audit studies nor natural experiments.
The objective of this chapter is to study the Chilean labor market and determine the
presence or absence of gender discrimination. In order to break past the limitations of earlier
works, an experimental design is used, the first of its kind in Chile. This study also allows
socioeconomic discrimination associated to names and places of residence in the Chilean
labor market to be tackled.
The study consists of sending fictitious Curriculum Vitae for real job vacancies published
weekly in the “El Mercurio” newspaper of Santiago. A range of strictly equivalent CVs in
terms of qualifications and employment experience of applicants are sent out, only varying in
gender, name and surname, and place of residence. The study allows differences in call
response rates to be measured for the various demographic groups. In the version of the
article presented, results are obtained for 6,300 CVs sent.
The following section contains a review of the relevant literature for this study. Meanwhile,
Section III contains all the methodological information associated to the implementation of
the experiment, which began to be applied in the last week of March 2006. Lastly, Section IV
contains the preliminary results recorded to date.

Literature Review
Labor market discrimination is said to arise when two identically productive workers are
treated differently on the grounds of the worker’s race or gender, when race or gender do
not in themselves have an effect on productivity (Altonji and Blank, 1999; Heckman, 1998).
However, there are never identical individuals. There are several unobservable factors that
determine individual performance in the labor market (see literature review in chapter 2).
The empirical literature attempts to face these problems by two alternative methodologies:
regression analysis and field experiments 7 .
The regression analysis is focused on analyzing the Blinder-Oaxaca decomposition (Oaxaca,
1973; Blinder, 1973) to determine how much of the wage differential between groups of
workers, by race or gender, is unexplained. This unexplained part is called discrimination.

problems involving detecting discrimination in the labor market using regression analysis and field experiments.

Developments in Chile have been centered on regression analysis applied to the gender gap.
See Paredes and Riveros (1993), Montenegro (1999) and Montenegro and Paredes (1999) as
an example. The conclusions from these studies are very limited. They lack several control
variables, related to cognitive and non-cognitive abilities and school and family
environments. In addition, preferences over non-market activities and experience of Chilean
female workers could prove to be a very important unobservable factor. More recently,
Núñez and Gutiérrez (2004) study social class discrimination in Chile under the traditional
Blinder-Oaxaca decomposition. They use a dataset that allows them to reduce the role of
unobservable factors by limiting the population under study and having better measures of
productivity (see more details on these references in chapter 2).
The above represent the traditional studies in this area. The present article is much more
closely related to a different line of research on labor market discrimination: experimental
studies 8 . These originated in Europe in the 1960s and 1970s, the ILO in the 1990s and
recently experimental techniques have been published in leading economic journals
(Bertrand and Mullainathan, 2004).
Experimental approaches can be divided into two types: audit studies and natural
experiments. The latter ones take advantage of unexpected changes in policies or events
(Levitt, 2004; Antonovics, Arcidiacono and Walsh, 2004, 2005; Goldin and Rouse, 2000,
Newmark, Bank and Van Nort, 1996). In Chile, as far as we know, there are no studies using
these kinds of variations.
There have been two procedures used to carry out audit studies. First, the personal approach
strategy, which sends individuals to job interviews or does job applications over the
telephone. Second, there is the strategy of sending written applications for real job vacancies.
The first procedure is the most subject to criticisms. It has been argued that it is impossible
to ensure that false applicants are identical. Also, testers were sometimes warned that they
were involved in a discrimination study and their behavior could bias the results. 9
The first experiments that used written applications were unsolicited jobs-applications and
posted to “potential employers”; these experiments tested preferential treatment in employer
responses and not the hiring decision. Later came the ones that sent curriculum vitae to real
solicitudes. Despite the fact that this latter technique overcomes the criticisms of the
personal approaches and tests the hiring decision 10 it does not overcome a common problem
of the audit studies raised by Heckman and Siegelman (1993) and Heckman (1998), which is
that audits are crucially dependent on the distribution of unobserved characteristics for each

racial group and the audit standardization level. Thus, there may still be unobservable
factors, which can be productivity-determining and not discrimination. Riach and Rich
(2002) accepted this criticism but pointed out that it is not easy to imagine how firm internal
attributes 11 could enhance productivity. They conclude that while Heckman and Siegelman
(1993) do not explain what could be behind those gaps the argument has “not been proven”.
The present study mainly follows the line of work developed by Bertrand and
Mullainathan (2004). In their study, the authors measured the racial discrimination
in the labor market, by means of the posting of fictitious curriculum vitae for job
vacancies published in Boston and Chicago newspapers. Half of the CVs were
randomly given Afro-American names and the other half received European
names. Additionally, the effect of applicant qualification on the racial gap was
measured; for this, the CVs were differentiated between High Qualifications and
Low Qualifications.
The authors found that the curriculum vitae associated to White names received 50% more
calls for interview than those with Afro-American names. They also found that whites were
more affected by qualification level than blacks. Additionally, the authors found some
evidence that employers were inferring social class based on the applicants’ names.

Experiment Design
As already indicated, the experiment consists of the sending out of CVs of fictitious
individuals for real job vacancies that appear weekly in the newspaper with the highest
circulation in Chile.
Each week, the work team selects a total of 60 job vacancies from the “El Mercurio”
newspaper of Santiago. A total of 8 CVs, 4 corresponding to men and 4 to women are sent
out for each vacancy. The details of the experiment design are presented here below.
3.1
Definition of Demographic Cells
We defined eight relevant demographic cells which determined the categories
being studied in the experiment. Thus, eight CVs -that are equivalent as regards
employment productivity but differ in the variables in question- were sent out for
each vacancy.

The cells were defined to serve the objectives of the study. Firstly, the study of
discrimination by gender requires men and women to be separated. Additionally,
socioeconomic discrimination is examined by means of two variables: surnames and
municipalities of residence. In order to reduce the number of observations required in each
case, these last variables were separated into two groups, the most extreme:
socioeconomically rich and poor municipalities; and surnames associated to the Upper
Classes and Lower Classes.
Since we have three dichotomous variables, the final number of demographic cells is 8
(2*2*2), as the following Table shows:
Hombre
Apellido
Apellido
Clase Alta Clase Baja
Mujer

Clase Alta Clase Baja
Comuna Ingresos

From the outset of the field work, in the last week of March 2006, each week approximately
60 job vacancies are chosen. Eight CVs are sent for each job vacancy, in other words, one
for each demographic cell. So, each week 480 CVs are sent, 240 to men and 240 to women.
A group of names, surnames and municipalities are established to satisfy the requirements of
each cell, with the names and municipalities chosen randomly for each vacancy.

Description of the source of job vacancies
The main source of job vacancies in Santiago is the “El Mercurio” newspaper, which
publishes every Sunday around 150 job vacancies, with a repeat rate of around 30%. The ads
are also available in the newspaper webpage, which facilitates access (see:
http://empleos.elmercurio.com/buscador/destacados/listado_destacado.asp)
To prepare the field work, a prior study was carried out on this source. To this effect, in the
month of January and the first three weeks of March 2006, all vacancies published were
analyzed in order to design the future mailing strategy. In effect, it was possible to conclude
from this study that it is necessary to prepare a CV bank based on three categories:
professionals, technicians (skilled workers) and unskilled workers. Other markedly male or
female categories were rejected and the approximate number of vacancies for each week was
calculated.
3.3
Creation of CV Banks.
As indicated above, job vacancies are grouped into three categories: Professionals,
Technicians and Unskilled workers. A person was assigned responsibility for each category,
and is in charge of selecting the weekly vacancies, as well as the production, sending and
supervision of the CVs sent.
9
D EPA RT A M EN T O D E EC O N O M Í A , U N I V ERS I D A D D E C H I L E
Each person in charge (three in total) has a CV bank obtained from the www.laborum.com
and www.infoempleo.cl websites. These are used as the base information for producing
fictitious CVs and comply with the profile of the most competitive applicant for the vacancy
selected.
Each set of 8 CVs is constructed so that its qualification levels and employment experience
are equivalent, in order to ensure that the applicants are equally eligible for the job in
question.
The central element in the training of the people in charge of this was to ensure that the 8
CVs sent for each vacancy had to be equivalent in terms of qualifications and human capital.
To ensure this, the coordinators of the study were supported by a research assistant that
supervised the work over the whole period and, especially, during the first weeks, until
ensuring the desired results.
3.4
Classification of municipalities
In order to facilitate the field work, the study is concentrated in the Metropolitan Urban
Region, which is divided into 34 municipalities.
To classify the municipalities in the two extreme segments, the socioeconomic classification
of households based on the 2002 Census designed by Adimark was used. This institution
classified from the CASEN 2003 Survey. Using this, it classifies the proportion of the
population by socioeconomic level in each municipality. The groups are ordered from higher
to lower level, ABC1, C2, C3, D and E.
For high income municipalities, 5 of the 6 with the highest proportion of the population in
segment ABC1 were chosen (the sixth was excluded because it is a municipality that also had
a higher proportion than the rest in segment D and E). On the other hand, for the low
income group municipalities, the 15 municipalities associated to a lower proportion of the
population in segment ABC1 and a greater proportion in the segments D and E were
chosen. In order to more clearly examine the impact of the municipality of origin, all other
municipalities of intermediate socioeconomic groups were left out.
The final list of the municipalities included in each group is presented in the Table below:

Classification and selection of names and surnames
The names and surnames were classified and selected according to the procedure used by
Núñez and Gutiérrez (2004).
Specifically, a sample of names and surnames was taken from the alumni register of the
Faculty of Economics and Business of the Universidad de Chile. Subsequently, a group of
students was chosen, who classified (based on their personal perception) these names and
surnames into: High Social Class, Middle Social Class and Lower Social Class.
For the purposes of the field work, only the names and surnames classified as Upper Class
and Lower Class were considered.
An example of the surnames used in each category is presented in the Table below.

Description of the field work
The three people responsible indicated above handle the weekly selection of job vacancies
that appear in “El Mercurio” on Sundays. They then construct the targeted CVs for each
vacancy, with the most competitive CVs, ensuring their equivalence, in order to ensure that
the only differentiating elements are the sex of the applicant, the social level, name and
surname, and the municipality of residence.
Apart from the people in charge, the team is made up of three other assistants. This entire
procedure is supervised directly by a Sociologist and an Economist who randomly reviews
the CVs sent.
The job vacancies selected and the lot sent for each vacancy are entered weekly into a
specially designed web page that allows all the vacancies to be reviewed, together with their
respective sets of CVs. The entry of that information into the web page is handled by an I.T.
expert.
A central aspect of this work is receiving the calls for the CVs sent. To receive these callsresponses, there is a fully dedicated man and woman team, ready to take the calls 24 hours a
day from Monday to Sunday.
There are 8 mobile telephones, each with a different number, assigned to each of the CVs of
the set; this ensures that the recruiters do not encounter repeated telephone numbers. The
people in charge of receiving the calls record the day, name of the applicant, the vacancy and
the phone number of the firm that selected the CV.
Each report is entered into the web page of the project, which allows for the regular
supervision of the calls received.
In parallel, job vacancy responses are also received by e-mail. Some job vacancies request emails. For this, a generic e-mail has been created for each CV. To date, 54 e-mails addresses
have been set up and they are checked every three days. As with the phone calls, the e-mails
are reported and entered into the web page of the project.

3.7
Identity of the fictitious applicants
Once the names and surnames are classified by categories, Upper Class and Lower Class,
they are then mixed so as to not use real names. Additionally, each fictitious applicant has an
artificial RUT 12 and an exclusive e-mail address.
To ensure the equivalence of each set of CVs, the age of the applicants was set at between
30 and 35 years of age, married with between one and two children at most.
3.8
Ensuring the equivalence of the fictitious applicants between cells
In order to ensure the equivalence of the 8 fictitious applications sent for each vacancy, the
other variables included in the CVs were controlled for similarity. For this, the following
decisions were made:
•
•
•
•
12
13
As regards the educational background of the applicants, those with university
education are considered Universidad de Chile graduates and where necessary, they
have postgraduate studies from the same University.
The school of the applicant and the home address are determined by the
municipality that they belong to. A bank of school names of each municipality is
used for this. However, to ensure homogeneous schooling the 8 CVs sent must
belong to the same category of socioeconomic background of the school 13 .
Additionally, each CV of the set of 8 has a unique telephone number different to the
other seven; however, these may repeat themselves among different groups of CVs.
The employment experience of the applicants is equivalent within each category
(professional, technician, unskilled worker) but different among each other. Thus,
professionals with greater time spent in the educational system have less years of
employment experience, meanwhile, unskilled workers have a longer track record in
the labor market. To maintain this equivalence, we have also set the number of jobs
that each applicant has had in the various categories and their employment history
continuity (absence of employment gaps).
National Identification Number.

Postgraduate studies of applicants are equivalent within the set of 8 CVs that are sent
for each vacancy. Within the set of 8 CVs, postgraduate studies must be from the
same university (Universidad de Chile) and in very similar areas or even identical
areas. Training courses must also be from equivalent institutions (Technical
Insitutes) and in similar or identical areas.
As a general rule, high quality CVs were sent for each vacancy. In other words, the
variables of employment history, education and training were drawn up to be
attractive to firms.
The pay expectations required, which generally have to be included in job
applications, were based on actual remuneration information of professionals and
technicians (from the web page www.futurolaboral.cl). The starting point were pay
levels required by a good candidate (of percentile 75 of that distribution) but,
subsequently, the remuneration was reduced to average levels. Each set of 8 CVs
sent for a vacancy had the same reference pay level and varied only slightly (in some
cases it was given as a range and in others as a specific reference).

Findings
The CV mailing process started in the last week of March. As we can note from Table 1, on
average, 68 vacancies have been applied for weekly, with a total of 11,016 CVs sent during
the 20 weeks of the project, and a response rate of around 14.65%. This rate is somewhat
higher than that obtained by Bertrand and Mullainathan (2004).

The response rate varies from week to week, probably depending on the labor market cycles
and economic expectations during the year. There is evidence that this expectations has been
declining from March until now.
Curriculums were sent to different job categories: professionals, technicians and unskilled
workers. In the appendix we present a list of type of qualification within the different job
categories. The average response rate by type of employment in Table 2 shows the same
evolution as the response rate. We can also note that unskilled and technicians have a higher
response rate than professionals. Professionals show a response rate of 12.1% compared to
14.2% for unskilled job announcements and 18.1% for technicians.

Calls were received after different number of days. However, the following graph shows that
more than 60% were received before day 10. This graph was done based on a Table shown
in the Appendix. The average number of days in answering was 12 days approximately for
professionals and unskilled was 14 days and for technicians was 8 days (see Table 3).

The resumes were sent by physical mail, email and fax. Table 4 shows the average number of
days they lasted in making a call back by type of sending. We can see that CVs that were sent
by physical mail received a call back in 18 days approximately and the ones sent by email
received a call back in 8 days. The response to the fictitious candidates could have been done
by telephone or by email.

We will look at the average response rate by the three dimensions considered in this paper.
4.1
Gender Effects
If we take a look at the gender based information, the response rates show very similar
levels: 14.9% for men and 14.6% for women. This difference is small and not statistically
significant (applying a test where the null hypothesis is the equality of the two proportions).
In other words, men and women seem to have the same probability of getting called to
interview.
If the gender based difference is looked at in the response rates within the High Class group
(by surnames), an slightly higher rate is obtained for women (15.3% vs 15.1%), in contrast to
the situation with surnames in the Lower Classes were the response rates is higher for men
(14.7% vs 14%). However, the differences are not statistically significant.

Neighborhood Effects
If we turn to the municipal dimension, the response rate of applicants from high income
municipalities is 15.1%, compared to a rate of 14.4% for applicants from low income
municipalities. These differences between municipalities, both on a general and on a cell
level, are on average higher than that observed in the case of gender. However, this
difference is not statistically significant to 90%.

Social Class Effect
A similar situation to the above may be observed when the response rates of fictitious
candidates with Upper Class surnames (15.2%) are compared with those with Lower Class
surnames (14.3%). Once again, the differences are not statistically significant. The largest
differences occur within the group of women and also within the high income municipalities
category.

In conclusion, surprisingly, relevant gender differences are not found. In addition, the
differences in response rates by municipalities or surnames are lower than the gender
differences, in fact they are not statistically significant.
The analysis of the response rates for professionals confirms in general the aspects found
above. There are no significant differences by gender, municipality or by surname.
4.4
Regression Analysis
Table 8 runs some complementary analysis using regression. As it can be seen, in none of
the specifications there is a change in the main conclusions. The dummy variables associated
to gender, municipality or surname are not significant.

Timing of the callbacks
The results shown until now allow us to say that there are no differences in callback rates
across groups. However, it could be possible to hypothesize differences favoring some
groups in the timing of the callbacks.
This is not the case, however, as it is shown in.Table 9. All the differences reported in the
number of days to receive a callback across groups are not statistically significant.

“Is there labor market discrimination among professionals in Chile? Lawyers,
Doctors and Business-people”
Abstract
This paper presents a complete analysis of the gender differences in three Chilean professionals
labor market: Business, Law and Medicine. In the analysis, we utilize a new and rich data set
collected for this effects. This data set contains information on labor market outcomes
(including labor history), on schooling attainment and schooling performance, on a complete set
of variables characterizing the family background of the individuals in the sample and on non
cognitive abilities.
Our results show that differences in wages attributed to gender are only present in the Law
profession. In the Business/Economics profession a vector of current family condition makes
the gender effect disappear and in Medicine taking into account hours worked, size of the firm
and region make also disappear the gender gap.
Specially important are shown to have a better level of self control in explaining wage
differences.

Introduction
Labor market discrimination is said to arise when two identically productive workers are
treated differently on the grounds of the worker’s race or gender, when race or gender do
not in themselves have an effect on productivity (Altonji and Blank, 1999; Heckman, 1998).
However, there are never identical individuals. There are several unobservable factors that
determine individual performance in the labor market. First, we do not observe individual’s
cognitive abilities 14 . Second, we do not observe individual’s non-cognitive abilities such as
personal motivation, self-determination, and locus of internal/external control or selfconfidence. Third, we do not observe pre-labor market discrimination conditions such as
family background and school environment 15 . Fourth, we do not observe individual past
expectations about how the labor market works 16 .
Regarding gender group differences, these can be found for market and non-market
activities and for types of jobs. There are gender differences for comparative advantages due
to: differences in gender roles in home production, differences in parental investment in
skills (Becker, 1991) and the transfer of family preferences (Fernandez, Fogli and Olivetti,
2004). And there are group gender differences in human capital investments as a result of
pre-labor market discrimination. Consequently, discrimination can influence human capital
investment before and after an individual enters the labor market.
Based on these facts and on the lack of studies in Chile which can face these issues, we
implemented a survey on professionals from three different careers in Chile: Law, Medicine
and Business, to analyze differences in their wages but reducing unobservable to a minimum.
They have all passed a university entrance selection test. They are comparable in their
academic formation. We have data on their university performance. We have data on their
social and family background. We have applied tem a test on non-cognitive abilities. We
have applied a survey to ask them real labor experience and family conditions now.
14
Neal and Johnson (1996) is a good example of how unobserved factors could be driving the results. They
study the role of pre-market factors in black-white wage differences controlling with a test administered to
teenagers prepared to leave high school in the US. They found that the adult black-white wage gap primarily
reflects a skills gap due to observable differences in family backgrounds and school environments.
15 O’Neil and O’Neil (2005) find that differences in productivity-related factors account for most of the
between-group wage differences in the year 2000 for the US. Differences in schooling and in skills developed in
the home and in school, as measured by test scores, are important in explaining black/white wage gaps. But the
gender differences in schooling and cognitive skills are quite small and explain little of the pay gap. Instead the
gender gap is largely due to choices made by women and men concerning the amount of time and energy
devoted to a career, as reflected in years of work experience, use of part-time work, and other workplace and
job characteristics.
16 See Altonji and Blank (1999) for a complete survey on race and gender discrimination and explanations of
the underlying theories.

Based on this complete and new dataset we have taken a regression analysis approach to
determine how much of the wage gap is left once the only difference among individuals is
gender.
Research in Chile have been centered on the traditional Oaxaca decomposition (Oaxaca,
1973; Blinder, 1973). Paredes and Riveros (1993), estimate the endowment and
discrimination effects for the period 1958-1990 17 . They provide evidence on discrimination
against females during the whole period examined. Montenegro (1999) and Montenegro and
Paredes (1999) analyze the gender wage differential by using quantile regression and the
Oaxaca decomposition. The evidence also shows stable and systematic differences in the
returns to education and to experience by gender along the conditional wage distribution. In
addition, it is also shown that discrimination is higher for women with more education and
experience. However, these conclusions of studies are limited. They lack several control
variables, related to cognitive and non-cognitive abilities and school and family
environments. In addition, preferences over non-market activities and experience of Chilean
female workers could prove to be a very important unobservable factor.
More recently, Núñez and Gutiérrez (2004) study social class discrimination in Chile under
the traditional Blinder-Oaxaca decomposition. They use a dataset that allows them to reduce
the role of unobservable factors by limiting the population under study and having better
measures of productivity as we do. However, this study has some limitations. One it is
related to the collection of the data. The survey was carried out by postal mail and had a very
low response rate, 30% approximately. Second, the survey was carried out on recently
graduated college students of Economics 18 which does not allowed to detect the effects of
labor experience. Third, it lacks of survey data on labor history and real experience, family
characteristics and preferences. Fourth, the survey had a very small sample size.
This paper faces these limitations by surveying 1,500 Alumni of the Universidad de Chile
from the following degree programs: 500 from Medicine, 500 from Law and 500 from
Business/Economics. Half of each group are women and half are men. We subsequently
analyze wage differences between women and men for each careers correcting the estimates
for post graduate schooling, labor market experience, parents schooling, married conditions
and cognitive abilities. Following recent literature (Heckman, Stixrud and Urzua, 2005) we
took the Rotter (1966) and Rosemberg (1965) tests for non-cognitive abilities. We have run
OLS regressions and ordered probit estimation to explain economic outcomes by a set of
explanatory variables.
17
18
Contreras and Puentes (2001) extended the analyses to 1996.
In Chile, high school students choose subjects, not colleges as in the US.

The results indicate that that differences in wages attributed to gender are only present in the
Law profession. In the Business/Economics profession a vector of current family condition
makes the gender effect disappear and in Medicine taking into account hours worked, size of
the firm and region make also disappear the gender gap. Specially important are shown to
have a better level of self control in explaining wage differences.
This structure of the paper is the following. Next section 2 present the econometric models.
Section 3 presents the data and summary of the descriptive statistics. Section 4 presents the
results and finally section 5 presents the conclusions.

The Econometric Models
In this section we will explain briefly the well known models in which it is usually study labor
market discrimination.
We are using two different specifications: OLS estimation and an ordered probit
estimation 19 . In each of these models we have a wage equation as a function of a set of
different explanatory variables:
Model 1: OLS
log wi = γ Fi + λ1 Exp + λ2 Exp 2 + λ3 N i jobs + J 'i Φ + X i'δ + S 'i Γ + T 'i Δ + H 'i Π + ε i
where F is a dummy variable that takes value 1 if female and 0 otherwise. Thus, the
coefficient γ measured the perceptual difference in wages that is lower because individual i is
female rather than male. In this setting, it is assumed that the market value in the same way
the characteristics of the individuals.
Exp is years of real labor experience and Exp2 is the squared. And Njobs is the average
number of parallel working activities each individual does in a year.
J’ is a set of variables related to characteristics of the job, it contains a dummy variable for
the level of responsibility in the job which take value 1 if the occupation is of high
responsibility 20 and 0 otherwise, a dummy variable for a big firm that takes value 1 if the firm
19
In a future version of this paper we will include a Oaxaca decomposition.
An occupation is set to be of high responsibility if its occupation code is related to the following categories:
members of the executive or legislative power and directives of public and private firms, such as managers of
business and company directors.
20
38
D EPA RT A M EN T O D E EC O N O M Í A , U N I V ERS I D A D D E C H I L E
has more than 500 workers and a dummy variable equals to 1 if the person works in the
metropolitan region.
X’ is a set of variables related to other personal characteristics such as a dummy variable that
takes value 1 if the person has done a postgraduate course, university performance measured
with a dummy variable that takes a value 1 if the person reproved a class and age.
S’ is a set of variables related to the person socioeconomic background such as mother’s and
father’s years of schooling and grades at secondary school 21 .
T’ contains two measures of non cognitive abilities explained later.
Finally, H’ contains three measures of current family situation such as a dummy for married,
number of children and a dummy for head of the household. An alternative specification
would have been to have a Heckman model
Model 2: Ordered Probit Model
I i = j if
where
α j +1 ≤ φ Hrsi + γ Fi + λ1 Exp + λ2 Exp 2 + λ3 N i jobs + J 'i Φ + X i'δ + S 'i Γ + T 'i Δ + H 'i Π + ε i < α j
j = 1,K ,8
Ii is an indicator variable for the wage intervals and Hrsi is the monthly hours worked by
individual i.

The Data
In this section we present a comprehensive descriptive statistics of the variables collected in
the survey and used in the estimations 22 .
We will look at different statistics of labor market outcomes, performance at University,
social and academic background, test for non cognitive abilities and current household
status. Each of these variables is meant to explain in same way differences between observed
gender gaps in wages.

Grades is Chile go from 1 to 7, having an average of secondary school performance of 6 is distinction.
The questionnaire and a complete field work resume are in the appendix.

We have collected approximately the same quantity of interviews for each type of degree (see
Table 1). That is 500 observations for each type.

Table 2 shows the list of variables included in the regression for the degree of Business and
Economics by gender.
Regarding labor outcomes we can see that there are gender differences on wages 23 . Women’s
monthly wage is 69% of men’s monthly wage, these differences can also be observed in the
tabulations of wage intervals. However, since women work less hours a month, women’s
hourly wage is only 81% of men’s hourly wage, and this is 97% if we look at the logarithm.
We also can note that female labor force participation is 81% and is lower than male labor
force participation which is 97%. Women have less accumulated experience and have less
parallel activities, although these differences are not high. 56% of men have a job of high
responsibility while 43% of women have the same level of responsibility in the job. We can
also observe that there are differences in the type of firm they work. 47% of men work in
firms with more than 500 workers, while 60% of women do the same.
We can note that more 15% of less women do a post graduate degree, although women
seems to have a better performance at University and at school (see grades). Mother’s
schooling is higher for women than for men. These latter may be related to the transmission
of preferences. There are not differences in socioeconomic background between men and
women. 8% of each group comes from a poor family and 15% of each group was raised in a
uni-parental home.
As we said before, we also collected measures of non-cognitive abilities by taking the Rotter
(1966) and Rosenberg (1965) tests for internal and external locus of control and self-esteem,
respectively 24 . The lower the index the higher is the degree of self control or self esteem. We
23 Exact wages were only reported for 20% of the sample approximately, however most people who did not
give the exact amount gave an interval. Therefore we have assigned the maximum of the interval to the wage.
We are anyway running ordered probit using the intervals of wages. There were also people who did not want
to answer this question therefore we have less data for this variable.
24 The tests are included in the questionnaire.

D EPA RT A M EN T O D E EC O N O M Í A , U N I V ERS I D A D D E C H I L E
can note than in average women got a lower degree of self control but a higher degree of self
esteem.
Finally, we think that measures of the current home situation could be important since it
may reflect preferences for home production activities. We can see that although the number
of children and the percentage of married men and women are the same only 28% of
women are head of the household whereas 96% of men are in the same situation.

Table 3 shows the summary of the descriptive statistics for the degree of Law by gender.
In this case the gap in monthly wages is 68% approximately in favour of men. However, we
can note that monthly hours worked by women are in average higher than hours worked by
men and so the gap reduces to 71% in monthly hourly wage and to 96% if we look at the
logarithm. We also can note that female labor force participation is 93% and is lower than
male labor force participation which is 99%, both are higher than in case of business.
Women have more accumulated experience and have slightly less parallel activities, although
these differences are also not high. We can also observe that the proportion of lawyers in job
positions with more responsibility is less than in the case of business/economics reaching
only 4% and 5% respectively. We can also observe that there are differences in the type of
firm they work. In this case, women also tend to work in big firms (51%) more than men
(31%).
We can note that 63% of women and men that study law do post graduate degrees. Again
women have a better performance at University and at school: a lower proportion of women
reprove classes and they have higher grades at secondary school. Mother’s and father’s
schooling are higher for women than for men. This may be again related to the transmission
of preferences. Only 6% of women come from a family of poor background, whereas 17%
of men are in the same situation. 20% of each group was raised in a uni-parental home.
The measures of non cognitive abilities behave in the same way. In average women got a
lower degree of self control but a higher degree of self esteem.
Finally, regarding the measures of current home situation present the following
characteristics. We can see that there are more differences between men and women in this
case. Married rate is lower for lawyers in average and even lower for women, also the
number of children is slightly lower for women. Although women head of the household are
also less than men, this rate is higher for lawyers reaching 37% of them.

Table 4 shows the summary of the descriptive statistics for the degree of Medicine by
gender.
In this case the gap in monthly wages is 76% approximately in favour of men. This is lower
than in the case of business/economics and law. In addition, we can note that monthly
hours worked by women are in average lower than hours worked by men and so the gap
reduces to 91% in monthly hourly wage and to 99% if we look at the logarithm. We also can
note that female labor force participation is 97% and is lower than male labor force
participation which is 100%, both are higher than in case of business and law. The
accumulated experience in terms of years of experience and number of parallel activities of
women and men are the same. We can also observe that the proportion of doctors in job
positions with more responsibility is nearly null for both gender. We can also observe that
there are not great differences in the type of firm they work. In this case, 90% of women
work in big firms and 86% of men. This latter statistics is higher than in the case of business
and law.
In addition, we can note that 97% of women and men that study medicine follow post
graduate degrees. This latter may be related to obtaining of specialities. Again women have a
slightly better performance at University and at school: a lower proportion of women
reprove classes and they have higher grades at secondary school. Mother’s and father’s
schooling are more similar among groups in this case and the level of parent’s schooling is
higher in comparison to the other to professions.
The measures of non cognitive abilities behave in the same way than the other to cases. In
average women got a lower degree of self control but a higher degree of self esteem. It is
worth noting that non cognitive abilities are higher in this professionals than in business and
law.
Finally, regarding the measures of current home situation present the following
characteristics. We can see that medical professionals observed in this sample have less
children than the other professional and women doctors have less children than men
doctors. Married rate is lower for women than for men, however men have a higher married
rate than the other two professions and women have higher married rate than lawyers but
lower than business women. Although, again only 31% of women are head of the household
in contrast to 99% of men.

The Results
Descriptive statistics presented before help us to shed some light in which are the
determinants of wages in the labor market.
In this section we will use these measures to see whether once we take into account some of
these differences we still have the gaps in wages we have in our data.
As we pointed out in section 2 we are using two different specifications: OLS estimation and
an ordered probit estimation.
Tables 5, 6 and 7 present the results of the OLS regressions for each type of degree
respectively. Regarding Business/Economics we can see that once the variables describe in
the sections before are included the coefficient associated to the variable female start
decreasing stadely until it turns to be not statistically significant in column 7. This latter
column is the one including the vector of current family condition. This vector does not
have a theoretical reason of why should be added in the wage equations however we added
this variables in order to control for preferences of looking for certain types of jobs.
Number of children and head of the household are positive and statistically significant. In
fact, we know that being head of the household present additional responsibilities to finance
household consumption.
Other important variables which are determinants of business people’s wages are experience,
the level of responsibility at the occupation, having a post graduate study and working in the
metropolitan region. All these four variables add a premium on a professional’s wage in
Business/Economics career.
Regarding professionals in the Law degree we can note that just as before the coefficient
associated to the dummy for female decreases steadily once different variables are added
progressively until it turns not significant in column 7. In this case, only the number of
children is a significant variable of the vector of current family conditions. However, this
vector is picking up all the effect of gender.
It is also new that in this wage equation the non cognitive ability test for self control is
statistically significant. That is the higher the level of self control the higher are the wages.
This is interesting and very intuitive to think, since lawyers need special abilities to be good
professionals. As before real experience, the level of responsibility and a post graduate
course helps to have higher wages.
Regarding doctors we can note that female is never a negative issue in terms of wages. The
only variables statistically significant in our regressions are the size of the firm in the sense
47
D EPA RT A M EN T O D E EC O N O M Í A , U N I V ERS I D A D D E C H I L E
that the bigger the number of workers in the firm the lower is the wage, and working outside
the metropolitan region give doctors higher wages. This latter may be due to scarcity of
these professionals in the rest of the country as well as special government premiums to
doctors working outside the metropolitan region.

Tables 8, 9 and 10 present the results of the Ordered Probit regressions for each type of
degree respectively. We think this model is more accurate because we did not have the real
level of wages as a continuous variables for most of the sample.
Regarding Business/Economics we can see that it is still the case that once the control
variables are included the coefficient associated to the variable female decreases to turn into
to zero in column 7. Again, the vector of current family conditions is driving this result.
It is also maintained the conclusion that the other important variables are experience, the
level of responsibility at the occupation, having a post graduate study and working in the
metropolitan region. At the same time, performance at University and the self control non
cognitive ability test are significant variables with the expected coefficients.
Regarding professionals in the Law degree we can note that contrary to the case above
women lawyers do have a cost in terms of wages because of being women. In this model,
there is strong significance of metropolitan region and age which are negative, and the self
control test is again statistically significant. Lawyers who have a better level of self control
got higher wages. It is maintained also that the number of children and being had of the
household are important variables in the wage equation whereas in this case this vector is not
picking up the effect of gender.
Regarding doctors the results are again very intuitive. We can observed that female turns to
be a statistically not significant variable explaining wages. The size of the firm, working
outside the metropolitan region and hours worked are statistically significant variables. It is
also true that self control and family conditions are also statistically significant variables.

Conclusions
This paper study differences in wages of three types of professionals in Chile: Business
women and men, lawyers and doctors.
Our preferred specification is an ordered probit model. In this specification we can see that
female does seem to have only a negative effect on wages for lawyers, even including current
family conditions. Business women and men differences disappear once the vector of
current family conditions are added. And doctors seems to have no differences in wages due
to gender.
Other important variables explaining differences in wages are the level of responsibility in
the job, having postgraduate studies, the size of the firm, a regional effect. And most
importantly, there is an important and positive effect of the non cognitive ability test that
measures self control.

Appendix to Chapter 2
This survey was applied to ex-alumni of the Universidad de Chile that studied Medicine, Law
and Business/Economics and who graduated at least eight years ago. The sample is made up
of 50% men and 50% women.
The survey was implemented by telephone. To offer the respondents an image of the survey,
a website has been designed to present the Survey, which provides a description of the
survey, its objectives and questionnaires.
The survey takes approximately 20 minutes and contains six modules: General Information,
Education, Employment History, Family Background, Individual History and Test of NonCognitive Abilities.

Sample Design
The survey is being developed without geographic restrictions. Since it is a telephone based
survey, there are no geographic boundaries. It is simply a case of locating the individuals of
the sample in the city where they may be.
The selection process of the sample was developed in the following stages.
A3.
Search for Names of Ex-alumni
First, a search was made for administrative information on ex-alumni in the Faculties of the
Universidad de Chile and centrally. We had several meetings with Central authorities of the
University who finally accepted to furnish us with a database of graduates of the University
from 1970 to 1997 from the three degree programs involved. This database is confidential
and contains the national identification number of the person, their name, year of
graduation, degree program and, in some cases, an address.
Table 1 shows the distribution of the original framework sample, obtained from the
administrative information of the Universidad de Chile.

Updating Ex-alumni Data
The addresses and other personal data on ex-alumni obtained from the administrative data
showed a significant proportion of incomplete records with outdated information.
In order to update the original information, 6,000 individuals were chosen, who were tracked
down in phone books and other sources to get their location data. After this search process,
the following distribution was obtained (See Table 2). This will finally be the real sample
framework from which the final sample is chosen.

Selection of the Sample
The definitive sample is chosen based on the real sample framework defined in the point
above.
The objective number of surveys for carrying out is 1,500. One third of these correspond to
each degree program, and in equivalent proportions between men and women.
In order to effectively obtain the surveys requested, it is necessary to have an over-sizedsample, to be able to cover the losses arising from people that cannot be found or that
refuse to participate in the survey. Based on earlier studies and considering the lack of
individual information available, we can consider a loss of 100%. Therefore, the selected
sample should be 3,000 individuals.
The selected sample is obtained by choosing 1,000 individuals graduated in each of the three
degree programs (Law, Medicine and Economics) randomly. The same number of men and
women are chosen within each degree program.
To complete the sample, by degree program, the same number of male and female graduates
by graduation year are chosen. Therefore, the final sample, displayed in Table 3, may be
characterized as probabilistic, stratified by degree programs and gender, with a nonproportional distribution among strata.

Pilot survey
Before implementing the survey, a pilot survey was carried out on the whole sample selected.
The general objective of this pilot survey is to evaluate the operation of the questionnaire by
means of a telephone interview. It also has the following specific objectives:
62

1. Review problems of content (difficulty of comprehension on the part of the
respondents, lack of response categories, etc.).
2. Evaluate the implementation periods.
3. Difficulty in contacting and locating respondents.
To carry out the Pre-Test, a sample of graduates that were not included in the selected
sample were extracted, from 70 cases of each of the degree programs chosen for the study.
These 70 cases were in turn divided evenly among men and women.

The Field Coordinator and the Survey Programmer were responsible for the training of the
telephone operators that carried out the pilot survey.
The training consisted of a presentation of the study, which was followed by a review of the
questionnaire. It was carried out in the morning of the first day of work of the operators
After the end of the pilot survey, the questionnaire was modified slightly to gather the
observations made through the implementation.

Questionnaire and Interviewer Manual
The Survey is designed for telephone as well as paper based implementation, in case an
interviewer should have to implement it so.
The Questionnaire that will finally be implemented is presented in the Appendix to this
chapter of the Report and is comprised of 5 modules of questions and two non-cognitive
ability tests that are to be found at the end there. The form covers areas such as: household
structure and identification, income, job, education, health, housing, family background and
perceptions. The modules are as follows:
•
Module A: General Information of the Respondent
Objective: Obtain information on sex, marital status, age and position within the
household.

Module B: Education
Objective: Obtain Information on prior education of the respondent and also on
activities subsequent to university. Questions are posed on the quality of the
secondary education received.
Module C: Employment History
Objective: Obtain complete information on the respondents employment activities
from their date of graduation. They are also questioned on their parallel activities and
job characteristics. For those who are currently inactive, questions are posed to
obtain information on the reserve salary.
This allows us to discover the real employment experience of men and women.
Module D: Family Background
Objective: Obtain information about the parents’ education and the emotional and
socioeconomic stability of the household during childhood. There are also questions
on the size of household, gender composition and education level of siblings.
Module E: Personal History
Objective: Obtain information on respondent’s marital history and common-law
wives, as well as children.
Test 1: Rotter Internal-External Locus of Control Scale
It is a four-item abbreviated version of a 23-item forced choice questionnaire
adapted from the 60-item Rotter scale developed by Rotter (1966). The scale is
designed to measure the extent to which individuals believe they have control over
their lives, i.e., self-motivation and self-determination, (internal control) as opposed
to the extent that the environment (i.e., chance, fate, luck) controls their lives
(external control). The scale is scored in the internal direction: the higher the score,
the more internal the individual. Individuals are first shown two sets of statements
and asked which of the two statements is closer to their own opinion. They are then
asked whether that statement is much closer or slightly closer to their opinion. These
responses are used to generate four-point scales for each of the paired items, which
are then averaged to create one Rotter Scale score for each individual.
Test 2 Rosenberg Self-Esteem Scale
It is a 10-item scale, designed for adolescents and adults; measures an individual’s
degree of approval or disapproval toward himself (Rosenberg, 1965). The scale is
short, widely used, and has accumulated evidence of validity and reliability. It
contains 10 statements of self-approval and disapproval to which respondents are
asked to strongly agree, agree, disagree, or strongly disagree.

Preparation of the Survey
Fieldwork preparation requires carrying out all the regular tasks, in other words, registration,
training, supervision, as well as preparing and providing the necessary material and inputs for
survey implementation.
The selection method for the interviewers was by invitation. These invitations were made to
interviewers that have worked in other similar surveys undertaken previously by the Centro
de Microdatos. In fact, 10 telephone interviewers were invited, who possessed previous
training in the same characteristics as the Pilot survey. In this particular occassion, they also
received an Interviewer Manual. All operators who implemented the survey have higher
education studies, either technical level or university.
The training activity took approximately 4 hours. All the questions of the questionnaire were
reviewed, and the concepts required to implement it were defined, as well as the aspects that
had to be emphasized in the survey, in addition to the clarification of any pertinent queries.
A product of this stage was the Interviewer Manual with all the final corrections.

Organization of the Work Team
The fieldwork team is finally composed of:
• A technical coordinator of the Survey, responsible for ensuring the correct
implementation of the methodology and quality standards. He/she is responsible for
verifying the correct implementation in the field, fulfillment of the sample sizes, and
the subsequent verification of the control tabulations for the final approval of the

“Ability, Schooling Choices and Gender Labor Market Discrimination: Evidence for
Chile”
Abstract
This paper presents a comprehensive analysis of the gender differences in the Chilean labor market. We
formally deal with the selection of the individuals into schooling levels and its consequences on the gender
gaps. Our approach allows for the presence of not only heterogeneity in observable variables but also
unobserved heterogeneity. We link this unobserved heterogeneity to unobserved scholastic ability. In the
analysis, we utilize a new and rich data set for Chile. This data set contains information on labor market
outcomes (including labor history), on schooling attainment and schooling performance, and on a complete set
of variables characterizing the family background of the individuals in the sample
Our results show that there exist statistically significant gender differences in several dimensions of the Chilean
labor market. Nevertheless, we show that these gaps critically depend on the schooling level of the individuals
considered in the analysis. For example, the results indicate that there are no gender differences in labor market
variables among college graduates (except in the case of hourly wages).
We interpret our results with prudence. Specifically, instead of interpreting our findings as decisive evidence of
the existence of discrimination in the Chilean labor market, we argue that future research based on better
information might indeed explain some of the unexplained labor market gaps presented in this paper. In this
context, our results represent a new and important attempt to provide a full understanding of the structural
causes of gender gaps in the Chilean labor market but they are not conclusive.

Introduction
Gender gaps in a variety of labor and educational outcomes (e.g. wages, earnings,
employment, schooling levels) are well documented. The structural reasons behind
these gaps, however, are not fully understood.
This paper contributes to the literature by studying gender differences in a
framework in which schooling decisions and labor market outcomes are
endogenously determined. Our framework also allows individual heterogeneity not
only from the point of view of observable characteristics but also unobserved
variables. We assume that individuals know this additional source of
heterogeneity, and they base their schooling and labor market decisions on it.
Unobserved heterogeneity plays a crucial role in our approach.
Ours is a challenging task for several reasons. First, a comprehensive analysis of
gender differences in a variety of outcomes is subject to the usual and
irremediable data limitations. Second, the natural complexity associated with
econometric models of multiple, endogenous, and correlated outcomes makes
these models usually not very empirically appealing. And finally, the fact that we
allow individuals decisions to depend on variables unobserved by the researcher
but known to the agent represents an additional challenge of our approach.
Nevertheless, we deal with each of these difficulties. First, we utilize a new data
set from Chile that contains detailed information on labor market and schooling
outcomes at the individual level. Second, we postulate a simple factor structure
model based on economic theory that simplifies the manner we can deal with
multiple endogenous variables. And finally, we interpret this factor as unobserved
heterogeneity since the researcher does not need to know the individual factor
(although it is assumed to be known by the individual). We argue that the factor
represents a combination of different scholastic skills (cognitive and noncognitive
skills).
As previously mentioned, we implement our approach using new information
from Chile. The Chilean case provides an interesting example of apparently huge
gender gaps in different dimensions of the labor market. Table 1 presents basic
information for a variety of schooling and labor market outcomes obtained from a
sample of males and females with ages between 28 and 40 years. 25
The evidence in Table 1 provides an initial flavor of the gender differences that
motivate the idea of this paper. A comparison of the schooling outcomes (Panel A
25
The information comes from the Social Protection Survey 2002 of Chile (SPS02) which is the source of
information used in this paper. This survey is described in detail in Section 2.

in Table 1) leads to conclude that, in average, (i) women are slightly more
educated than males, (ii) women are less likely to repeat a grade in both primary
and secondary school, and (iii) women show a better performance in school than
males (measured by the average grade in secondary school). However, this
educational advantage of women over men seems to have no consequences on the
labor market. The evidence in Panel B illustrates this point. It shows that males
overwhelmingly dominate females in every single dimension of the labor market
(monthly earnings, employment, and experience).
This paper studies the factors explaining these gender differences in labor market
and schooling outcomes.
The paper is organized as follows. Section 2 describes the data. Section 3 presents
evidence on the differences in labor market outcomes between males and females
using a conventional approach. Section 4 introduces our model and discusses its
empirical implementation. Section 5 presents a discussion of our results. Section 6
concludes.

Data
This paper uses information from the Chilean Social Protection Survey 2002
(SPS02). This survey was designed to identify and analyze the most important
determinants of the social security decisions (participation in the social security
system) among Chileans. In order to do this, a representative sample of 17,246
participants of the Chilean pension system was interviewed between June of 2002
and January of 2003. For each individual in the sample, the survey collected
information on household composition (ages, genders and schooling levels of the
household members as well as their relations with the interviewee), current
employment status, different sources of income, schooling (maximum schooling
attained, average grades in primary and secondary school, characteristics of the
primary and secondary school attended), family history (mother's and father's
education, characteristics of the place of residence where the individual grew up,
and number of previous relationships), labor history since age 15 or since 1980
depending on the year the individual became 15 years old (periods of employment,
unemployment and inactivity), training programs (information on the three most
important training programs since 1980), expectations (job, retirement and life),
savings (instruments and amounts), and a set of variables describing the
individual's knowledge of the characteristics and performance of the Chilean
pension system.
69
D EPA RT A M EN T O D E EC O N O M Í A , U N I V ERS I D A D D E C H I L E
We use a sample of individuals with ages in the range of 28 and 40 years. This
group represents approximately the 21% of the original sample (3,566 versus
17,246). 26
We restrict the ages of sample for several reasons. First, since the information on
labor history begins only in 1980 (or since age 15), by using individuals 28-40
years old we assure that our sample report complete labor histories from age 18.
Second, since schooling is an important ingredient of our analysis, by excluding
individuals 27 years old and younger we focus our attention on individuals that
have most likely reached their final schooling level. 27
Finally, it is worth noting that the current Chilean schooling system was designed
only in the early 80s. Therefore, since our analysis includes information on the
characteristics of the primary and secondary schools in which the individual was
enrolled, by restricting the analysis to the individuals with ages 28-40, we assure
that such information is available for most of our sample.
Table A.1 presents the summary statistics of the variables used in this paper.

The Conventional Gender Gap Analysis
The gender differences in labor market outcomes are usually analyzed in the
context of linear models in which the variable of interested is regressed on the
gender dummy variable and set of additional controls. The coefficient associated
with the gender dummy is interpreted as the estimated gender gap. Given its
popularity, our first attempt to quantify gender gaps follows closely this idea.
Table 2 presents the results from the following model of (log) hourly wages (lnW):
26
Our sample is obtained after considering the following exclusions. We first exclude the military sample (57
individuals) and individuals reporting as occupation "family member without salary" (12 individuals). Then, we
exclude individuals 27 years old or younger and 41 years old or older. With this the sample reduces from 17,177
to 5,439. Finally, individuals with missing values in any of the following variables are excluded: "years of
education", "mother's education", "father's education", "growing up in poverty" and "growing up in a single
parent household". This exclusion reduces the sample to the final 3,566 individuals. It is worth noting that the
final exclusion is required since for each individual we need to have valid values for the controls entering in the
schooling decision model presented in Section 3.1.
27 A more general analysis of the schooling decisions would require a dynamic model for schooling choices.
The SPS02 does not allow us to carry out such analysis.
70
D EPA RT A M EN T O D E EC O N O M Í A , U N I V ERS I D A D D E C H I L E
ln W = α + ϕ Gender + β X + U
(1)
where Gender represents the gender dummy (Gender=1 if individual is Male and 0 if
Females), X represents individual's observable characteristics, and U is the error
term in the regression. In this simple model, the (conditional) gender gap is
simply ϕ. Each column in Table 2 represents a different specification of (1). In
particular, column (A) presents the results of a model in which we include the
characteristics of both the place of residence and occupation in the vector of
controls X. Column (B) adds a set of variables controlling for the individual's
accumulated experience and column (C) adds to the controls in (B) a set of
variables controlling for schooling levels. The results indicate that males make
approximately 23% more than females in terms of hourly wages. This gender gap
is statistically significant regardless of the column analyzed.
The last model in Table 1 (column D) includes a correction for the fact that the
labor market outcome is reported only for individuals working (Heckman, 1974).
This is particularly important given the gender differences in employment rates
reported in Table 1 (panel B). Thus, the model in column D is:
ln W = α + ϕ Gender + βX + U if wage is observed (D=1)
D = 1[γZ + V > 0]
(2)
where 1[A] is an indicator function that takes a value of 1 if A is true and zero
otherwise, Z is a vector of observables and V represents the unobservables.
D=1[.] is the censoring rule for wages. In Z we include variables such as number
of children, whether or not the individual grew up in a poor household, mother’s
and father’s occupational status. The estimated gap after correcting for selection
is 29% and it is statistically significant. Thus, after controlling for selections, we
not only find a significant but larger gender gap in wages (compare to the ones
estimated without using the correction). This fact illustrates the importance of
paying particular attention to individual's endogenous decisions (in this case
employment decisions) when analyzing gender gaps. We exploit this point in the
following section.
The analysis of gender gaps in wages is interesting and important but it represents
only one dimension of many among which males and females can differ. We first
extend our analysis to the case of monthly hours worked. We model (log) hours
worked using a linear-in-parameter models similar to (1) and the same set of
controls as the ones utilized for wages. Table 3 presents the estimates of gender
gaps in this case. The structure of this table is identical to the one in Table 2. The
71
D EPA RT A M EN T O D E EC O N O M Í A , U N I V ERS I D A D D E C H I L E
results from columns (A), (B) and (C) suggest that males work approximately 11%
more hours per month than females. This difference is statistically significant and
it is stable across the three specifications. However, the last column in Table 3
presents (again) a different story. Unlike the results for wages, the correction for
selection significantly reduces the gender gap in hours worked. The estimated gap
is only 0.04% and it is not statistically significant.
We also extend our analysis to employment status. In this case, we use a probit
model instead of a linear regression model. Table 4 presents the results for three
different specifications. For each specification, we present both estimated
coefficients and estimated marginal effects. 28 The results indicate that males are
22% more likely to report an employment (during the month previous to the date
of the interview) than females when schooling and experience are excluded as
controls. When schooling or schooling and experience are included as controls the
estimated gap is 14%. The gaps are statistically significant regardless of the
specification.
In summary, the results show that men dominate women in every labor market
outcome. Additionally, the results are robust across different specifications and
only in the case of hours worked and after controlling for selection we find
neither sizeable nor statistically significant gender differences.
Notice that up this point we have utilized the individual's schooling decisions and
accumulated experience as exogenous regressors. However, in principle these
variables can also be subject to gender differences. Tables 5 and 6 present
evidence on this point. The implications of separate analyses of schooling choices
and accumulated experience on our previous results are left for the next section
where they are discussed in the context of a more general framework than the one
used here. 29
We model accumulated experience assuming that, whatever experience level is
observed in the sample, it is the result of a decision involving three alternatives:
less than 10 years of experience, between 10 and 15 years of experience, and more
than 15 years of experience. This decision is assumed to depend on the schooling
level of the individual as well as on his family background (mother's and father's
education, broken home, age, and growing up in poverty). Given this set up, we
compute the gender gaps in accumulated experience by estimating a multinomial
probit model. Table 5 presents the estimated coefficients and marginal effects.
28
The marginal effects are computed at the mean values of the variables in the model.
This is particularly important if we consider that schooling decisions and accumulated experience are
probably endogenous variables in the context of the models presented in Tables 2, 3 and 4. The model presents
in the next section deals with this possibility.
29
72
D EPA RT A M EN T O D E EC O N O M Í A , U N I V ERS I D A D D E C H I L E
The estimates associated with the gender dummy are all significant and suggest
that males are considerably more likely to report more experience than females.
Specifically, males are 40% less likely to report less than 10 years of experience
and 29% more likely to report more than 15 years of experience than females.
The analysis of gender differences in schooling decisions is also relevant in the
context of the previous results. On the one hand, if males are in fact more likely
to report higher schooling levels than females (after controlling for observable
characteristics), then the gender differences in labor market outcomes (including
accumulated experience) could be simply interpreted as the result of gender
differences in accumulated human capital. On the contrary, if females are more
likely to report higher schooling levels than males, then the estimated gender
differences in labor market outcomes could be interpreted as downward biased
estimates of the actual gaps.
Table 6 sheds light on existence of gender gaps in schooling decisions. It presents
the coefficients and marginal effects obtained from a multinomial schooling
choice model. The model is estimated using the maximum schooling levels
reported by the individuals in the sample. The schooling levels considered are:
primary school, secondary school, some post-secondary education, and complete
tertiary education (college graduates). The results show that (if anything) females
are more likely than males to reach higher schooling levels.
The advantage of females over males in schooling achievement/attainment is
confirmed in Table 7. This table presents the estimated gender gaps for three
variables measuring schooling performance: probability of a grade repeated during
primary school, probability of a grade repeated during secondary school, and
average grades during secondary school. For each variable we consistently observe
that females outperform males. Males are 7% and 4% more likely to repeat a grade
during primary and secondary school, respectively, and males in average have a
significantly lower grades during high school than females (0.31 points of test’s
standard deviation).
Therefore, the evidence presented in Tables 6 and 7 leads us to conclude that
females should be better prepared than males to face the labor market. This also
implies that by not including the gender differences in schooling variables our
previous results might be underestimating the actual unexplained gender gaps (or
discrimination). We analyze this possibility by introducing a more general model
in which schooling decisions, schooling achievement, employment decisions,
accumulated experience, hours worked and hourly wages are modeled jointly.

Heterogeneity

(2006). Heckman, Stixrud and Urzua (2006) postulate and estimate a model with
two underlying sources of unobserved heterogeneity that they interpreted as
abilities (cognitive and noncognitive abilities). Conditioning on the observables,
these factors account for all of the dependence across choices in the model. They
show that both abilities play a crucial role explaining a variety of labor market and
behavioral outcomes.
In this paper we postulate the existence of only one underlying factor representing
unobserved heterogeneity. This is mainly due to the fact that we do not have a set
of cognitive and noncognitive variables in the SPS02 sample. Consequently, we
interpret the source of unobserved heterogeneity as a combination of both
cognitive and noncognitive abilities. 30 The identification of its distribution is
discussed in Section 3.4 below.
Let θ denote the unobserved heterogeneity or latent ability. We assume this latent
ability determines the individual's schooling and labor market outcomes, and that
there are not intrinsic differences between males and females regarding θ, so that
we can work with an overall distribution for θ. 31
4.1
The Model for Schooling
Each agent chooses the level of schooling, among S possibilities, such that he
maximizes his benefit. Let I s represent the net benefit associated with each
schooling level s (s={1,…, S }) and assume the following linear-in-the-parameters
model for I s :
I s = ϕ s Gender + β s X s + α sθ + es
for s = 1,K ,S
(3)
30
We expect to extend our model to a multi-factor model in which we can precisely distinguish between
cognitive and noncognitive abilities.
31 The alternative would have been the estimation of gender specific distributions. We consider this an
attractive possibility. However, given the data limitations (sample size) and the large number of parameters in
the model, we prefer to follow a simple analysis by considering an overall distribution for θ. Future research
should consider the potential differences in unobserved heterogeneity between males and females.

here ϕ s represents the gender gap associated with the schooling level s, X s is a
vector of observed variables determining schooling, β s is the associated vector of
parameters, α s is the factor loading associated with the latent ability, and es
represents an idiosyncratic component assumed to be independent of θ, and X s .
The individual components {e s }s =1 are mutually independent. All of the
dependence across schooling choices comes through the observable, X s , and the
latent ability θ.
S
The agent chooses the level of schooling with the highest benefit. Formally,
s* = argmax {I s }
{
s∈ 1,K,S
}
(4)
where s* denotes the individual’s chosen schooling level. Notice that conditional
on X s (with s = 1,K ,S ) and θ, equations (3) and (4) can be interpreted as a standard
discrete choice model.
4.2
The Model for Accumulated Experience
The model also treats accumulated experience as an endogenous outcome.
Specifically, after deciding the schooling levels, agents are assumed to pick their
experience levels A different alternatives. As in the schooling model, given the
schooling level s, we assume a linear-in-the-parameters specification for the
benefits associated with the experience level a(s) (I a (s ) ) :
I a ( s ) = ϕ a ( s ) Gender + β a ( s ) X a + α a ( s )θ + ea ( s )
for a( s ) = 1,..., A and s=1,…, S
where ϕ a (s ) is the gender gap, X a is the vector of observed variables, β a (s ) is the
associated vector of parameters, α a (s ) is the factor loading, and ea (s ) represents an
components {ea ( s ) }a =1 for any s are mutually independent. Finally, the observed
idiosyncratic component assumed to be independent of θ, and X a . The individual
A
experience level A * ( s*) (where s* represents the schooling level observed in the
data) is interpreted as

A * ( s*) = arg max {I a ( s ) } .
a ( s *)∈{1,..., A}
4.3
The Model for Hourly Wages and Monthly Hours Worked
For hourly wages and monthly hours worked, we consider schooling/experience
specific models. Consider first the model for wages. Denote by s and a(s) the
schooling and experience level attained by the individual. Wages ( Ya (s ) ) are
modeled using a linear specification:
ln Ya ( s ) = ϕY ,a ( s ) Gender + β Y ,a ( s ) X Y + α Y ,a ( s )θ + eY ,a ( s )
for s = 1,K ,S and a( s ) = 1,..., A
where ϕ a (s ) is the gender gap, X Y is a vector of observed controls, β Y ,a ( s ) is the
vector of coefficients, α a ( s ) is the coefficient associated with the latent ability, and
eY ,a ( s ) represents an idiosyncratic error term such that eY ,a ( s ) ⊥ (θ, X Y )
for any
a(s)(=1,..., A ) and s(=1,…, S ).
A parallel strategy is used to model hours worked. Let H a ( s ) denote the monthly
hours worked given schooling level s and experience level a(s). Thus, we assume
ln H a ( s ) = ϕ H ,a ( s ) Gender + β H ,a ( s ) X H + α H ,a ( s )θ + ea ( s )
for s = 1,K ,S and a( s ) = 1,..., A
where ϕ H ,a ( s ) is the gender gap, X H is a vector of observed controls, β H ,a ( s ) is the
vector of coefficients associated with X H , α H ,a ( s ) is the parameters associated
with the latent ability, and eH ,a ( s ) represents an idiosyncratic error term such that
eH ,a ( s ) ⊥ (θ, X H ) for any a(s)(=1,..., A ) and s(=1,…, S ).

4.4
The Model for Employment
Let I E ,a ( s ) denote the net benefit associated with the alternative of having an
employment (versus the alternatives of unemployment or out of the labor force)
given the schooling level s and the accumulated experience a(s). As in the previous
cases, we assume a linear-in-the-parameters specification for I E ,a ( s ) :
I E ,a ( s ) = ϕ E ,a ( s ) Gender + β E ,a ( s ) X E + α E ,a ( s )θ + eE ,a ( s ) for s = 1,K ,S , a( s ) = 1,..., A
(5)
where ϕ E ,a ( s ) , β E ,a ( s ) , X E , α E ,a ( s ) , and eE ,a ( s ) are defined as before. Finally, the
error term is such that eE ,a ( s ) ⊥ (θ, X E ) for any a(s)(=1,..., A ) and s(=1,…, S ).
We use (5) to model the employment decisions observed in the data. Specifically,
if we let DE ,a ( s ) denote a binary variable such that is equal to 1 if the individual is
employed and 0 otherwise, we estimate a binary model assuming that
DE ,a ( s ) = 1 I E ,a ( s ) > 0 where 1[.] is (again) the indicator function.

Schooling Performance: The Measurement System
The identification of the model can be established using the arguments developed
in Carneiro, Hansen, and Heckman (2003) and Hansen, Heckman, and Mullen
(2004). The identification strategy assumes the existence of a set of
measurements. As explained in the next section, these measurements are
associated to the individual’s schooling performance.
Let T i (i=1,…,n C ) denote the i-th measure. We distinguish the unobserved ability
from the observed measure T i . This is important since T i is likely to depend on
the characteristics of school as well as on the family background of the individuals
by the time of the test. Thus, if X T denote these characteristics, we have
Ti = βTi X T + α Ti θ + eTi
for i = 1,..., nC
where eTi ⊥ (θ , X T ) and eTi ⊥ eT j for any i, j ∈ {1,..., nC } such that i≠j.
77
D EPA RT A M EN T O D E EC O N O M Í A , U N I V ERS I D A D D E C H I L E
Since there are no intrinsic units for the latent ability, we need to normalize one
of the loadings in the system to unity to set the scale of the latent ability.
Therefore, for some T i (i=1,…,n C ), we set α Ti =1.
Notice that our assumptions imply that conditional on observables (variables
contained in X), the dependence across all measurements, choices and outcomes
come through the unobserved heterogeneity (θ). Notice that if θ were observed,
we could use a matching type of approach to control for this dependence
(selection). Instead, we estimate the distribution of the unobserved ability and
then control for the dependence. Finally, we assume that θ measures the same
thing for males and females.
4.6
Implementing the Model
The model with unobserved heterogeneity has the following ingredients: the
schooling decision problem, the linear models for hourly wages and monthly
hours worked (by schooling level s and experience level a(s)), the models for
employment (by schooling level s and experience level a(s)), the model for
accumulated experience (by schooling level), and finally, the system of
measurements or school achievement. Unobserved heterogeneity appears as
determinant of each of these components. In this paper we assume that θ is
distributed according to a two-component mixture of normals. Formally,
(
)
(
)
θ ~ p1 N μ1 , ∑1 + (1 − p1 )N μ1 , ∑ 2 .
2
2
with this assumption we allow a flexible functional form for the unobserved
heterogeneity.
Following the empirical strategy utilized in Section 3, we estimate the schooling
choice model and the experience models using multinomial probit models. Then,
we implicitly assume that the idiosyncratic shocks in the equations describing the
net utilities are assumed to be jointly normally distributed. The four schooling
levels study used here are: primary school, secondary school (or high school),
some tertiary education (or some college graduates), and complete tertiary
education (or college graduates). For accumulated experience we use three
categories: less than 10 years of experience, between 10 and 15 years of
experience, and more than 15 years of experience.
78
D EPA RT A M EN T O D E EC O N O M Í A , U N I V ERS I D A D D E C H I L E
In estimating the model, and since there is no sequential decision process, we use
the schooling and experience level reported at the time of the interview. 32
For the models of wages and hours worked we use the information for the month
previous to the interview. The same applies in the case of employment status.
This is consistent with what we use in Section 3.
The measurement system uses the following variables: Average Grade during
Secondary Education, Repeated Grade during Primary Education and Repeated
Grade during Secondary Education.
We normalize the mean of the factor to zero, and we normalize the loading to be
equal to one in the equation for the Average Grade during Secondary Education
Tables 8A and 8B display the variables used in the empirical implementation of
the model, as well as the normalization assuring the identification of the model.
The model is estimated using Markov Chain Markov Chain Monte Carlo Methods
(MCMC). See Appendix A for a formal discussion of the method used in this
paper.
4.7
Main Results
Table 9 presents the gender gaps in hourly wages obtained from the model with
unobserved heterogeneity. The estimated gaps are in general sizeable and
statistically significant. We do not observe clear patterns either by schooling
and/or experience levels, although we consistently estimated the largest gender
gaps among college graduates (regardless of the experience level considered). In
this group we estimate that males make between 36% and 38% more per hour
than females. These numbers are larger than those presented in Section 3. But
Table 9 also presents a range for the gender gap in wages which goes from -6%
(but non significant) for high school dropouts reporting less than 10 years of
experience to 38% for college graduates with between 10 and 15 years of
experience. Importantly, in only two cases we estimate a gender gap below 15%.
32 In the case of experience, we use the retrospective information provided by the respondent (labor history).
The labor history is reported from age 15 or since 1980 depending on the year the individual became 15 years
old. For details see Section 2.

Therefore, our evidence indicates the existence of wage differentials that cannot
be explained by observed or unobserved characteristics.
As in the case of wages, the results obtained for hours worked show a range of
values for the gender gaps. These are presented in Table 10. We observe that the
point estimates are between -6% (high school dropouts with less than 10 years of
experience) and 18% (high school dropouts with between 10 and 15 years of
experience). In this case however, less than a half of the estimates are statistically
significant. For example, among high school graduates and college graduates we
do not find significant gender differences. This is consistent with the evidence
presented in Section 3, although the numbers in Table 10 show a broader picture
of the gender gaps (if any) in hours worked.
Table 11 presents the results for employment. Two are the main results here.
First, we observe, in general, a reduction in the estimated gap when we move from
low to high experience levels (the only exception is observed among high school
graduates). Second, the results suggest that schooling also helps to reduce the
estimated gaps (there are only two exceptions in Table 11). In fact, among college
graduates the estimated coefficients are
-0.12 and -0.23 for experience levels
“between 10 and 15 years” and “more than 15 years”, respectively, 33, 34 so the gap
favor females in this case. However, as in the case of hours worked, only few
estimates are statistically significant, and when significant, they are usually
associated with low schooling and experience levels.
Table 12 presents the results obtained for the four multinomial choice models
used to study accumulated experience. The evidence in Table 12 shows how the
gender gap reduces with schooling. Specifically, the significant gender differences
estimated for high school dropouts and high school graduates are 100% larger
than the ones obtained among individuals with some college. Interestingly, among
college graduates we do not find significant differences between genders.
Our analysis of gender gaps in variables associated with the labor market leads us
to conclude that (1) there are differences between males and females that cannot
be explained with observable or unobservable characteristics, and that, in general,
(2) these differences are larger among individuals reporting low schooling level
and they almost vanish among the more educated individuals. 35
33
For the group of individuals reporting more than 15 years of experience and a college degree, the gender
dummy perfectly predicts the labor status: the 29 women in this category reported a job during the week
previous to the interview.
34 These coefficients are the point estimates of the parameters associated with the gender dummy variable, so
they need to be interpreted cautiously since they do not represent the marginal effects.
35 The only exception to this point, and an important one, comes from the analysis of hourly wages.
80

The model also allows us to analyze the gender differences in schooling
attainment and schooling achievement. It is worth recalling that the evidence
presented in Section 3 already suggested that females outperform males in these
two dimensions (see Tables 6 and 7). Table 13 and 14 repeat that analysis but now
incorporating unobserved heterogeneity (latent ability).
Table 13 presents the gender gaps in schooling decisions. The results show (again)
that females are more likely than males to reach higher schooling levels. When
compared with those in Table 6, we see that the effects are now larger. Something
similar occurs in the case of “repeating a grade during primary school”, “repeating
a grade during secondary school”, and “average grades during high school”. The
results are shown in Table 14. The evidence in this table suggests that females
outperform males, that the differences are statistically significant and that they are
larger than the ones presented in Table 7. Specifically, when comparing the
estimated gender gaps across tables we obtain 18% (0.26 versus 0.22) and 41%
(0.17 versus 0.12) increments in the gender coefficient associated with “repeating
a grade in primary school” and “repeating a grade in secondary school”,
respectively. In the case of “average grade during secondary school” we obtain an
increment of 6.4% in the gender gap (0.33 versus 0.31).
5
Can Unobserved Heterogeneity Explain the Gender Gaps in the Labor
Market?
From the evidence presented in this paper we must conclude that this is still an
open question. Our results do indicate that, after controlling for unobserved
heterogeneity, there are non significant gender differences in a variety of labor
market variables among educated individuals (e.g., hours worked, accumulated
experience, employment), but we still find gender differences among the other
schooling groups. These differences can in principle be interpreted as “pure”
discrimination. However, this interpretation requires several qualifications.
First, our empirical strategy assumes that a one dimensional model of unobserved
heterogeneity is sufficient to capture and control for selection (endogeneity)
across different margins (decisions). Nevertheless, previous studies have shown
the existence of at least two underlying sources of unobserved heterogeneity when
explaining labor market outcomes and social behavior. 36 In this context, our one36
See Heckman, Stixrud, and Urzua, 2006; Urzua, 2006; Cunha, Heckman and Navarro, 2004.
81
D EPA RT A M EN T O D E EC O N O M Í A , U N I V ERS I D A D D E C H I L E
dimensional model might be only partially capturing the unobserved heterogeneity
in the data. The consequences of incorporating additional sources of essential
heterogeneity on our results are hard to predict. Thus, in principle, we cannot
discard the possibility that what we interpret as “unexplained gaps” in the one
dimensional case, can be in fact “explained” by, for example, heterogeneity in
other unobserved traits (e.g. noncognitive abilities) or preferences (e.g.
preferences for leisure). 37
Second, and following up on the previous point, it is interesting to notice that in
our results the coefficients associated with what we identify as unobserved
heterogeneity are not always significant. The strongest effect of unobserved
heterogeneity are obtained for the schooling variables (Tables 13 and 14), and
accumulated experience (Table 12). Although the effects are sizeable for the other
outcomes, they are usually non-statistically significant. This suggests that our
source of unobserved heterogeneity is more closely related to scholastic ability 38
which apparently is not significantly valued in the Chilean labor market after
schooling and experience levels are taken into account. Nevertheless, there might
be other sources of unobserved heterogeneity that are in fact priced in the labor
market. This again illustrates the potential benefits of extending the model to
multiple dimensions of unobserved heterogeneity
A different consideration regarding the robustness and interpretation of our
results can be made by noticing that we implement the model by assuming the
existence of a single distribution of unobserved heterogeneity in the sample. The
consequences of allowing gender-specific distributions on our previous results are
(again) hard to predict, but we believe that the complications of such extension
would most likely dominate any potential new insights. This since the
identification of gender-specific distribution has additional complications and it
relies on even stronger assumptions that the one already made. 39 Besides, from an
37 It is worth noting that the assumption of a single source of unobserved heterogeneity can be
relaxed depending on the availability of more comprehensive information at the individual level.
These needs for better and more comprehensive information come from the identification
argument of the models. Recall that the source of unobserved heterogeneity in this paper is
identified using the schooling achievement variable. In order to identify additional sources of
heterogeneity we would need additional variables in the measurement system. The availability of
information on personality traits, IQ tests, or time preferences could allow the identification and
estimation of more general models of unobserved heterogeneity.
38 Before we interpret the source unobserved heterogeneity as a combination of cognitive and noncognitive
abilities.
39 Specifically, even though we can assure the identification of gender-specific variance/covariance matrices, the
identification of gender-specific mean differences in the distribution of unobserved heterogeneity would
require the existence of at least one discrimination free variable. The selection and existence of such variable(s)
is non trivial is arguably as well. See Urzua (2006) for details.
82
D EPA RT A M EN T O D E EC O N O M Í A , U N I V ERS I D A D D E C H I L E
intuitive point of view, we do not find a priori deep reasons to believe that there
are gender differences in the distributions of unobserved heterogeneity. It is
because of this remarks that the estimation of gender-specific distribution is left
for future research.
6
Conclusions
In this paper we present a comprehensive analysis of the gender gaps in a variety
of labor market outcomes for Chile. The analysis is carried out using two different
approaches. The first approach follows the literature by estimating linear and
nonlinear models of a variety of variables on different observable controls and the
gender dummy. This approach does not pay attention to potential selection
problems (endogeneity). The second approach is more general. It allows for the
presence of individuals’ unobserved heterogeneity that is assumed to be the cause
of the endogeneity problems in the conventional approach.
Our main results are robust across the approaches. They suggest the existence of
gender gaps in labor market variables that cannot be explained by observable or
unobservable characteristics or by underlying selection mechanisms generating
endogeneity. Nevertheless, the findings from the model with unobserved
heterogeneity indicate that the gender gaps critically depend on the schooling
level of the individuals considered in the analysis. This is particular important
among college graduates. For this group, the gender differences are in general
non-significant.
The evidence also demonstrates that females outperform males in schooling
achievement and schooling performance. This is observed regardless of the
approach, but we find the stronger effects in the model with unobserved
heterogeneity. These gender differences favoring women represent an argument
against the conventional idea that labor market differences can be interpreted as
the result of differences in the human capital between genders. Obviously, this
conclusion assumes that the utilized variables are good proxies of the actual
human capital accumulated by the individuals.
Overall, the estimates in this paper could lead us to conclude that women are
effectively discriminated in the labor market with the largest gender gaps observed
among the less educated people. However, we prefer to interpret our results
cautiously. We believe that the availability of better data and the estimation of
83

even more general models than the one considered here could indeed explain
some of the unexplained estimated gender gaps.

Notes: (a) Hourly wages, monthly hours worked and employment models are estimated for four different schooling categories (primary,
secondary, some tertiary and complete tertiary) and three different levels of accumulated experience (less than 10 years, between 10 and
15 years, and more than 15 years). In each case, the labor market outcome refers to the previous month individual's outcome; (b)
Accumulated experience is modeled with a multinomial choice model. The categories considered are: less than 10 years, between 10 and
15 years, and more than 15 years. The level of accumulated experience is the total work experience reported at the time of the interview;

Notes: The accumulated experience corresponds to the retrospective information reported by the individual at the time of the interview. The shooling level corresponds to
the schooling level declared in the sample. Post-secondary education includes includes technical education (complete and incomplete). (a) Among high school dropouts, the
characteristics of the place of residence perfectly predict the labor status, so those variables are excluded in these cases. (b) For the group of individuals reporting more
than 15 years of experience and a college degree, the gender dummy perfectly predicts the labor status: the 29 women in these category reported to be working (34 out of
37 males report to be working). Since the gender coefficient is the main interest of this table we do not include this model here.
