RÉSUMÉ
Les analyses traditionnelles du marché du travail s’avèrent incapables d’expliquer le paradoxe
apparent entre un taux de chômage relativement modéré dans un pays tel que le Pérou (environ 10%,
taux peu sensible aux fortes fluctuations macro-économiques) et la perception d’une grave crise de
l’emploi. Une explication possible pourrait résider dans le fait que cet indicateur statique en coupe
instantanée ne mesure pas les flux élevés entre les situations d’emploi et d’inemploi.
Pour analyser ces questions, il est nécessaire de conduire une analyse dynamique sur données de
panel. Nous avons ainsi construit un panel national d’individus en âge de travailler pour la période
1997-1999 à partir de l’enquête péruvienne auprès des ménages (ENAHO). Comme d’autres études
réalisées dans des pays en développement, nous constatons qu’il existe une importante mobilité de
l’emploi au Pérou. Nous trouvons également que la plupart des transitions interviennent entre emploi
et inactivité plutôt qu’entre emploi et chômage. Le taux de chômage permanent apparaît très faible et
le chômage serait donc essentiellement un phénomène frictionnel.
Pour aller plus loin, nous avons élaborés des profils de transition inconditionnels, incluant les
caractéristiques individuelles et du ménage, telles que le genre, l’âge, et le niveau d’éducation, associé
avec chaque état de transition. Finalement, après avoir examiné ces transitions sur le marché du travail
et les biais de sélection possibles, nous avons estimé un modèle logit multinomial. Ce modèle nous a
permis d’apprécier l’incidence (conditionnelle) des caractéristiques individuelles et des ménages ainsi
que des différents chocs sur les états de transition en matière d’emploi.
ABSTRACT
Traditional labor market analysis based solely on the net unemployment rate fails to explain the
apparent paradox between a relatively moderate unemployment rate in Peru (around 10%, with a weak
sensibility to wide macroeconomic fluctuations), and the fact that unemployment is one of the major
issues in Peru. One possible explanation is that this static indicator of cross section net unemployment
balance is compatible with high flows in and out of employment states.
To address these issues we needed to conduct a dynamic analysis using panel data. Using the Peruvian
national household survey (ENAHO), we constructed a panel of working age individuals at the
national level for the period 1997-1999. Like previous work in developing countries, we found that
there is an important degree of job mobility in Peru. We also found that most of the transitions occur
between employment and inactivity instead of between employment and unemployment. We also
showed that the rate of permanent unemployment is very low so that unemployment would be
essentially a frictional phenomenon.
Further, considering the different transition states, we elaborated an unconditional transition profile,
including individual and household characteristics, like gender, age and education levels for example,
associated with each transition status. Finally, after examining these labor market transitions and the
possible sample selection bias, we estimated a multinomial logit model. This model allowed us to
appreciate the (conditional) incidence of individual and household characteristics as well as the effects
of different shocks on the labor transition states.

INTRODUCTION
Unemployment is considered to be one of the major issues in Peru. However, the level of
unemployment, estimated around 10%, is comparable to what is observed in other Latin American
countries and, most importantly, is characterized by a weak sensitivity to wide macroeconomic
fluctuations.
This apparent weak sensitivity of unemployment rates to macro economic fluctuations is possibly
related to the level of labor mobility in Peru. Actually, some evidence exists indicating that labor
mobility in Peru is very high and that most of labor transitions occur between employment and
inactivity. These flows in and out of the labor market cannot be captured by a traditional analysis
based on the unemployment rate. Therefore, this static indicator of cross-section net unemployment
balance fails to explain what really happens in the Peruvian labor market.
However, to study labor mobility, we need panel data. Panel data allows us to follow the same
individuals in the labor market during a given period and to observe if they move or not from one
labor state to another. The Peruvian national household survey (ENAHO) allowed us to construct a
large panel of working age individuals at the national level for the period 1997-1999. Thus, we could
conduct a dynamic analysis to verify if labor mobility is indeed high in Peru and if permanent
unemployment really exists. Also, we have examined factors determining labor mobility, focusing
particularly on individual characteristics associated with labor market transitions.
The first section summarizes the labor market situation during the nineties showing the evolution of
the unemployment and the GDP growth rates. This section also presents the principal results obtained
by previous studies concerning labor mobility in Peru. The second section gives some information
about the surveys used to construct the 1997-99 panel and how this panel was constructed. This
section also presents statistical tests in order to check for selection bias in our panel. Finally, the third
section analyzes determinants of labor market mobility in the urban and rural sectors in a descriptive
and econometric way.

PROBLEM STATEMENT
1.1. Economic performance and the labor market in the 90’s in Peru
During the nineties, the Peruvian Government implemented a macroeconomic stabilization program
and an important set of structural reforms, especially a significant labor market liberalization. The
economic outcome of these policies was a strong economic growth between 1992 and 1997. But,
between 1997 and 2000, the economic activity slowed down considerably (Figure 1). According to
official figures, the most dynamic sectors during the first period were those of raw production,
construction, financial sector and services.

Note: Unemployment rates for Metropolitan Lima
The labor market performance was only mildly affected by this highly contrasted economic evolution.
Even if the participation rate grew considerably over the period 1992–1997, the rate of unemployment
did not increase and the proportion of inactive people fell. The labor market was characterized by a
high job creation. According to official figures (1998), the employment growth was most pronounced
in small enterprises, fewer than ten workers, operating in the service sector. During the second period
(1997-2000), economic activity slowed down sharply and this slowed down had an adverse impact on
the labor market and especially on employment growth.
However, the performance of the labor market was also affected, particularly during the first period,
by the radical labor liberalization reform implemented in 1991. This reform and, particularly the
reduction of job protection and the creation of new kinds of job contracts, like part time and limited
time contracts, improved labor market flexibility and increased the rate of turnover. The consequences
were a fall in the average employment duration and a large increase in labor mobility during this
period (Chacaltana (1999), Diaz and Maruyama (2001)).
1.2. Main results of previous studies of labor mobility in Peru
Labor mobility has been rarely analyzed in Peru, the principal reason being the lack of suitable data.
Panel data over a continuous period has existed in Peru only since 1996, when the INEI implemented a
panel dimension in its ENAHO survey. This new survey allows us to construct a quarterly urban panel
for 1996 and to follow up on people selected during this year.
Currently, there are three important studies of labor mobility in Peru and all use the quarterly panel of
1996. The first was undertaken by the Peruvian Ministry of Labor in 1998 (MTPS, 1998). This study
was first improved by Chacaltana (1999), who also used an urban panel of 1997-98, and then by Diaz
and Maruyama (2001). These studies confirmed that the mean duration of unemployment in Peru is
very short. Actually, permanent unemployment seems not to be a very important problem, less of
0.1% of unemployed people stay in unemployment more than one year. However, the authors found
other interesting results, mainly that labor mobility is very important in urban Peru, more than 40% of
the active people changed labor market status during the year, and the authors observed that the most
important transitions in the labor market occur between employment and inactivity status, and vice
versa. Moreover, the authors identified individual characteristics that have important effects on labor
market mobility like sex and age, females and young people are the most affected by transitions.
5
These results could be questioned on some points. First, the authors did not take into account the
unemployment seasonality during the year. In addition, they did not check the quality of the quarterly
panel used. These gaps could produce some bias in their interpretations and conclusions. Moreover,
these studies analyzed only urban households and were focused on the unemployment problem
(mainly on the duration of unemployment). At present, a complete study about labor transitions in
Peru does not exist.
2.
DATA AND VARIABLES
2.1. The ENAHO surveys and the 1997-99 panel
The ENAHO surveys have been developed by the INEI on a quarterly basis since 1997. These surveys
have a national coverage, including both urban and rural areas, and deal with all the permanent
household residents. The surveys principal objective is to give information on the household living
conditions and they consist of four questionnaires. One of these questionnaires is the “Questionario
general” (general questionnaire) that gives information about the characteristics, education, health and
employment, of the dwelling and household member’s and about expenditures and social transfers. In
this paper, we used the ENAHO surveys of the last quarters of 1997, 1998 and 1999. The numbers of
individuals in the samples were respectively: 31,748; 33,325 and 18,786.
These surveys have a panel dimension that allowed us to follow some of the households and
individuals during these three years. In 1997, the INEI selected some dwellings as panel dwellings and
the household and individuals living there were identified. A relatively large number of individuals
can thus be traced from one survey to the following ones. We focused on working age people,
14-65 years old. To construct the panel, we used the individual identification code and then
information about sex, age and names. Finally, we obtained a large panel of 6006 individuals for the
period 1997-1999.
2.2. The selection bias issue
The individuals in the 1997-1999 panel represent only 38% of individuals older than 14 years in 1997
(see table 1). The difference is closely linked to the panel attrition caused by a combination of
different factors-sample construction, migration and missing answers-that are not necessarily
randomly distributed. Therefore, the “panel people” are not completely representative of the rest of the
sample and we needed to check the quality of our panel by comparing the characteristics of individuals
in the panel data against those not present in the panel in the 1997 survey.
At first glance, in 1997, the individuals present in our panel seemed to have the same characteristics as
those not present in the panel. But, tests carried out showed some significant difference at 1%, 5% and
10% between the two samples. More precisely, in the panel sample, there were more people from
Lima and less from the South and Central Sierra. Moreover, we observed more household heads and
more partners but fewer children and other relatives. In the panel, more individuals have primary
education and less have university education. We also observed a lower proportion of skilled people, a
smaller number of hours worked during the week, in the main and secondary jobs, and a higher
proportion of people who want to work more hours. Finally, there were a higher proportion of legal
owners, a lower proportion of tenants or of owners without title and a higher proportion of people with
working assets.

LABOR MOBILITY IN PERU
In contrast with the other dynamic studies about labor mobility and specially those concerning
unemployment phenomena, our study used a larger panel data set. This panel was not only
characterized by a longer time period of 3 years but was also larger in its coverage; we used a national
sample instead of only an urban sample. Using the last quarter of each year allowed us to analyze
labor mobility without the interference of seasonal effects.
3.1. The descriptive analysis
First, we presented mobility transition matrices in order to grasp the importance of labor transitions
between the different labor market status, employment, inactivity and unemployment, and then we
examined the labor mobility profile.

3.1.1.
Observed characteristics of labor market mobility in Peru
In Table 2, we examined flows into and out of different labor market status as well as those that
remain in the same labor market status throughout the 1998-99 period. First, we observed that, in Peru,
labor mobility is very important, 27% of the working age population, and “permanent” unemployment
is nearly non-existent and also “permanent” inactivity represent only 16% of observations. The most
important transitions in the labor market occurred between employment and inactivity, 16%.
Secondly, we observed that the level and characteristics of labor mobility differ between the urban and
rural sectors. Labor mobility was higher in the urban sector. In this sector, transitions from
employment to inactivity were predominant while the reverse was true in the rural sector, especially
for women. Third, women seemed to be more “mobile” than men, especially in the rural sector.
These differences are related to their production and labor market characteristics. In the urban sector
there are more salary workers and the effects of the labor market reform were larger. Moreover, the
reservation wage for urban inactive people is higher than in rural areas, especially for the young and
for the women. This may explain why we have a higher proportion of “permanent inactive” people,
especially females, in the urban sector. In the rural sector, also families are larger and the proportion of
agricultural producers is higher. Therefore, it is hard to differentiate between production and domestic
activities. Because, most of these activities are agricultural, they are affected by seasonality.
Individuals, especially the children and others relatives in the household move very easily from
domestic to production activities (and vice versa). This explains why the proportion of permanently
inactive people is relatively lower in this sector.

Source: ENAHO Panel 1997-99, build by the authors
In Tables 3 and 4, we analyzed labor mobility during three different periods (1997/98, 1997/99 and
1998/99). The lines refer to the labor status of the individuals in the first year, whereas the columns
refer to the status of the same individuals one and two years later.
We observed that more than 70% of employees and 50% of inactive people did not change their labor
market status in those years. The proportion of employees that transitioned directly from employment
to inactivity is higher than the proportion of employees who entered or exited unemployment. We also
confirmed that “permanent” unemployment was lower and that labor transitions were different in the
rural and urban sectors. For example, in the rural sector, a higher proportion of unemployed and
inactive people transited directly to employment. These transitions are consistent with the fact that, in
the rural sector, “permanent” inactivity and “permanent” unemployment were relatively lower,
especially for males.
9
We also observed the effects of the economic recession, which started in 1997, on the labor mobility.
Labor market mobility changed between 1997-1998 and 1998-1999, especially in the urban sector. In
this sector, in the latter period there were relatively fewer “permanent workers” and more “permanent
inactive” people. The economic recession did not increase transitions from employment to
unemployment but increased transitions from employment to inactivity. In the rural sector, the
changes were less important but the differences between males and females were more pronounced.
For males, the proportion of “permanent” workers was lower. There were more “permanent” inactive
people and the proportion of “permanent” unemployed individuals was zero. At the same time, exits
from employment increased whereas entries to employment decreased. The proportion of males who
transitioned directly from unemployment to inactivity increased nearly threefold. For females we
observed the opposite situation; and in particularly we observed an increase in the proportion of those
who transitioned to employment.

Notes: E = employed, U = unemployed and I = inactive.
In the previous sections, we observed that unemployment in the urban and rural sectors was very low
and that most labor market transitions occurred between employment and inactivity. The small number
of unemployed people forced us, in what follows, to merge the inactive and unemployed people. This
aggregation can be also justified by the Peruvian unemployment characteristics, observed before, and
especially by the fact that Peruvians do not have a particular interest in declaring themselves as
unemployed or as inactive (there is no unemployment benefit system).
Figures 2 and 3 below show how complex labor market transitions can be in Peru and highlight
differences between urban and rural sectors. It is interesting to note that nearly 21% of individuals in
the urban sector but only 9% in the rural sector could be considered as “permanently not working”
(inactive or unemployed) in each of the years of the observed period. These individuals can be referred
to as the hard core of “permanent” inactive people, representing respectively over two-thirds and a half
of all inactive individuals observed each year.
In 1999, almost half of inactive individuals in the two sectors were in fact “transient inactive”-persons
experiencing some labor market transition during the three-year period. Static unemployment rates had
low sensitivity to macroeconomic fluctuations, in part because they were absorbed by transient
inactives. The almost constant percentage of non-working people observed each year is in fact the net
result of compensating inflows and outflows of working and non-working individuals. Individuals
permanently employed represented only 44% in the urban, and 62% in the rural working age
population. We also observed that the longer the individual remains in the “non working” status, the
lower his probability of re-entering the working status.

3.1.2.
Labor mobility profile
We made dynamic labor market profiles showing the incidence of labor mobility according to
individual demographic and economic characteristics.
We obtained a profile of “mobile” people- i.e. people who went out or into employment- “permanent”
inactive or unemployed people and those who are “always” employed. This exercise was particularly
useful to characterize these different populations, but it could not examine causality between
individual characteristics and the different labor market transitions. The specific effects of the different
variables were examined later in the econometric part of the paper.
In Tables 5 and 6 we presented these profiles for urban and rural sectors and, in addition, we tested for
means differences. For example, in the urban sector, the profile of individuals in a status of
“permanent” inactivity (and unemployment) relative to those in a status of “permanent employment”,
corresponds on average to younger individuals and to a higher proportion of women. Therefore, these
individuals were less likely to be heads of household or to live as couples, but they were more likely to
be children. They lived in smaller households and in households where the number of children
younger than 10 was smaller. Moreover, a smaller proportion of these people completed primary
education and a larger proportion were still students. Regarding the labor market status of the
“permanent inactive” people the year before, the proportion of these people who were already inactive
or unemployed was higher and the proportion that were employees, lower. Also, “permanent inactive”
people were less skilled and worked fewer hours but were also less likely to have a secondary job.
Finally, the “permanently” inactive people seemed to have a relatively higher standard of living. They
lived in households with a higher number of income earners and most of them had working assets.
In the rural sector, the profile of “permanent inactive” people was quite different. In Particular, relative
to “permanent” workers, these individuals were more likely to be children or partners and others
relative. The proportion that was already inactive or unemployed was very high. They were also likely
to work in the informal sector.
The profile of “mobile” individuals was similar to the profile of “permanent inactive” people. In
particular, both groups were relatively young and included a higher proportion of women. But there
were also some differences. In the urban sector, the proportion of “mobile” people with secondary
education was higher. Individuals leaving the employment status (S) came from households with a
higher level of human capital and a lower dependency rate. They had more luxury and working assets
and lived in better dwellings. The proportion of those who were employed before was lower and the
proportion of those who were inactive was higher. Finally, “mobile” urban individuals had informal
jobs more often and worked in small enterprises.
In the rural sector, the profile of “mobile” and permanent inactive was almost the same. The only
important difference was that “mobile” rural individuals were less likely to have jobs in the secondary
sector than “permanent” employees. Rather, they were more likely to be tertiary sector employees.
We also observed some differences between individuals entering the labor market compared to those
leaving it. In the urban sector, labor market entrants (E) were likely to be heads of household and less
likely to be partners. Therefore, they were more likely to live in households with more children
younger than 10 years old and in households with a lower level of human capital. Moreover, they were
more likely to have completed their studies and to be obliged to have a secondary job. Finally, they
seemed to have relatively lower standards of living and fewer assets.
In the rural sector, differences between the two kinds of “mobile” people were almost the same as in
the urban sector. The only differences were that entrants had higher probabilities of being children
than those leaving the employment status. Also, they were employed more often in the secondary
sector and they worked relatively more hours per week.

Thus, the analysis of transition matrices showed us that the labor mobility in Peru is high and
permanent unemployment did not really exist, especially in the rural sector. Moreover, we found that
the most important labor market transitions occurred between inactivity and employment and that the
labor market mobility differed greatly between rural and urban sectors, mobility was relatively higher
in the later one, and across periods of time. Finally, we observed that age, sex, education level and
living conditions seemed to have important effects on labor market mobility.
3.2. The determinants of labor market transitions
In the next section, we expanded on the knowledge of the principal factors that determine labor market
transitions in Peru.
In commenting on the labor transition profile, we have examined the unconditional risk that
individuals with given characteristics may experience any of the labor market transitions. For a more
analytical purpose, we considered the relative risks conditional on the other factors that determine
labor market transitions.
We estimated the determining factors of different forms of labor mobility between 1998 and 1999
using a multinomial unordered logit model, because our dependent variable is a categorical variable
with four values corresponding to each of the labor market transitions, “always” employed (O),
“permanent” inactive or unemployed (I), exit out of employment (S) and enter into employment (E).
3.2.1.
The model
This model was designed to estimate the impact of the different explicative variables on each of the
forms of labor mobility. The model predicted the probability that an individual with given
characteristics will experience one of the four labor market transitions. In order to identify the model
one of the labor market transitions was taken as the baseline case. Different sets of coefficients were
obtained for each state. We first commented on the statistical significance of the regression
coefficients of the logits. In accordance with Long’s (1997) graphical presentation, we studied the
impact of discrete changes in explanatory variables on the probability of ending in one of the four
categories (O, I, E or S), in terms of odds ratio (relative risk ratio) given that we were interested in
labor market dynamics. In others words, we were interested in knowing how each variable affects the
odds of a person being “permanent” inactive, going into employment or going out of employment
relative to being “always” employed (the base case). The multinomial logit is:
(1)
Pr ( y i = m xi ) =
exp( xi β m )
∑ exp( x β
j =O , I , E , S
i
j
)
Where Y is the dependent variable with m nominal outcomes and Pr ( yi = m xi ) the probability of
observing outcome m given x.
To identify the model we decided that β O = 0 (the base case is “always” employed). Because
exp( xi β O ) = exp( xi 0) = 1 , the model is commonly written as:
(2)
Pr ( y i = m xi ) =
exp( xi β m )
pour m ≠ O
1 + ∑ I , E , S exp( xi β j )
16
We expressed the model in terms of the odds. The odds of outcome m (m=I, E et S) relative to the
base case outcome (O) given x, reads:
exp( xi β m )
(3)
Pr ( y i = m xi )
Pr ( y i = O xi )
1+
∑ exp( x β
i
j
)
j = I ,E ,S
=
= exp( xi β m ) , avec m= I, E, S et β O = 0.
1
1+
∑ exp( x β
j = I ,E ,S
i
j
)
Therefore exp( xi β m ) represented the relative probability of being E or S relative to being O for a
unit change in xi . The interpretation became easier because, as Long notes, the value of the factor
change in the odds does not depend on the value of the level of the variable considered or on the level
of the other variables, as in the case of the marginal impact (Long 1997: 169).
Most of the explanatory variables used in the estimations of the model were dichotomous. However,
there were some continuous variables, e.g. age, and some categorical variables, e.g. age group. The
interpretation of the coefficients for these variables was also easier: for the former, we had to interpret
the coefficients relative to the average and for the latter we had to interpret the coefficients to the
omitted category.
We complemented the interpretation of results using odds figures (see appendices). As Long (1997)
explains, “The large number of coefficients makes it difficult to see patterns in the results. If you also
keep track of which coefficients are statistically significant, the difficulty increases. And odds ratio
plots make it simple to find patterns among the coefficients.”
3.2.2.
Main regressions results
Because, labor mobility differs in the urban and rural sectors we estimated models separately for each
sector:
In the urban sample, like in the descriptive analysis, sex and age had important effects on labor
mobility. However, in this case the relative probability of being “permanent” inactive” relative to
being “always” employed increased with age. Moreover, no differentiated impact of age was found on
outcome S (exit out of employment) and E (entry into employment). Women had higher probabilities
of being “permanently” inactive or “mobile”, especially of being in E, relative to being “always”
employed. No difference was found in the sex variable for I, E or S.
Logically, we observed the opposite situation for the household heads (most of them are males)
relative to their partners. Household heads have lower probabilities of being permanently inactive but
are more likely to be in category S relative to O (this result could be related to the higher degree of
labor mobility in the urban sector).
Higher levels of education seemed to protect against “permanent” inactivity. The impact of education
was not significantly different for E and S. Students, who were relatively younger, were more likely to
be “permanent” inactive or “mobile” relatively to “always” employed.
Labor market variables, like in the descriptive analysis, had high and significant effects on labor
mobility. On the one hand, the odds of being “mobile” and of being “permanent” inactive were higher
for people who were inactive during the previous year. On the other hand, work experience and skills
seemed to protect against “permanent” inactivity. Moreover, people who worked in the primary or
secondary sectors, relative to the tertiary sector, had higher probabilities of being “permanent” inactive
than of being “always” employed. Likewise, people with a public job relative to people with informal
jobs had lower probabilities of leaving employment or of being “permanent” inactive. Finally, the
17
individuals with higher probabilities of being “permanent” inactive or of entering employment were
those who had the “worst” jobs. They were the ones who wanted to work more hours per week or to
have a secondary job.
Most of the variables linked to living conditions, e.g. the kind of dwelling, were not significant.
However, the probability of being “permanent inactive” relative to being “always” employed
increased with the level of human capital of the household (income effect). The dependency rate had
the same effects on the relative probability of being “permanent” inactive as it does on that of being
“mobile”.
The variables related to events showed interesting results. For example, having previously exited from
an economic sector apparently decreased the probability of being “permanent” inactive but increased
the probability of leaving employment (relative to being “always” employed). Changes in the number
of income earners had differentiated effects on S and E (income effect) they increased the probability
of being in E but decreased the probability of exit employment.
In the rural sample, variables were less significant but the results and the coefficients were somewhat
different from the variables in the urban sample. Age affected the probability of entering into
employment. This probability increased with the age for all categories relatively to being “always”
employed. The effect of sex was stronger than in the urban sector (this is consistent with the
descriptive analysis). The effect of being a student was also stronger. On the other hand, the effect of
being skilled was different. Skilled individuals had relative higher probabilities of entering into
employment. The effects of been previously inactive and the effect of the level of household human
capital were not as strong as in the urban sector. Finally, two variables that were insignificant in the
urban sector were significant here. Dwelling quality, represented by a dummy for living in a dwelling
with solid walls, and a dummy for having working assets both increased the probability of being in E
relative to being “always” employed.
Finally, we conducted three kinds of Wald tests to verify the robustness of our estimations. The first
one (last column in tables 7 & 8) indicated that most of our explanatory variables had significant
effects in all the categories of the dependent variable. The others test (Table 9 and 10) confirmed that
the construction of our dependent variable and of the explanatory variables with many modalities, e.g.
sectors of activity, were correct.

CONCLUSION
We have shown that labor mobility in rural and urban sectors is indeed relatively very high, that
permanent unemployment does not really exist and that most of the labor market transitions occur
between employment and inactivity (and vice versa). Further, we observed that labor market mobility
is higher in the urban sector than in the rural areas and that it does not affect the same people. Some
individual characteristics, e.g. sex, age and education level, labor market characteristics, e.g. labor
market status, sector of activity and desire to work more hours, household characteristics, e.g. level of
human capital in the household and dependency rate, and variables of change, e.g. change of sector of
activity, seem to be important determinants of labor market transitions.
Some previous studies showed that labor mobility increased during the first half of the nineties and
found that this increase was related to labor market reform, for example see Saavedra and Torero
(2000). We found some evidence that labor market mobility was also enhanced by the economic
recession, which started in 1997.
Thus, taking into account labor mobility allows us to understand why, even if static unemployment
rates and permanent unemployment are very low, unemployment is one of the major issues in Peru
and also why the unemployment rate is not very sensitive to wide macroeconomic fluctuations. Static
labor indicators, like the unemployment rate, are not appropriate for understanding what really
happens in the labor market in a developing country like Peru.

Notes: How to interpret the odds figures?
We have considered 4 outcomes of Y:
O = Always employed (the base outcome)
I = Always inactive
S = Exit out of employment
E = Entry into employment
As Long (1997: 171) explains, in each figure we need to think of the magnitude of the odds ratio
exp( β m O ) as the distance between an outcome m (m= I, E or S) and the base outcome (O). The
larger the odds ratio, the greater the distance. If an increase in xi increases the odds of E over O for
example, then E would be plotted to the right of O and vice versa. The base outcome (O) is located at
0 on the bottom scale to indicate that a change in xi does not change the logit of O relative to O. A
factor change scale is printed at the top of the figure. This is a logarithmic scale with each value equal
to the exponential of the value on the bottom scale. Finally, the lack of statistical significance is shown
by a connecting line. The intuition is that if a coefficient is not statistically significant, then the
variable does not differentiate two outcomes and so those outcomes are linked.
The explanatory variables used in odds figures were:
ageB97 = age in 1997
sex97 = sex in 1997
head97 = household head in 1997
autrpa97 = other relatives
fam97 = living in a couple
yearEd97 = years of education
student97 = still student in 1997
labor97 = inactive or unemployed in 1997
bran971 = primary sector
bran972 = secondary sector
sin97 = working in the public sector in 1997
skill971 = skill in 1997
