CESifo Working Paper No. 4127
Money Laundering as a Financial Sector Crime
A New Approach to Measurement, with an Application to Italy
Abstract
Anti–money laundering regulations have been centred on the “Know-Your-Customer” rule so far,
overlooking the fact that criminal proceedings that need to be laundered are usually represented by
cash. This is the first study which tries to provide an answer to the question of how much of cash
deposited via an official financial institution can be traced back to criminal activities. The paper
develops a new approach to measure money laundering and then proposes an application to Italy, a
country where cash is still widely used in transactions and criminal activities generate significant
proceeds. In particular, we define a model of cash in-flows on current accounts and proxy money
laundering with two indicators for the diffusion of criminal activities related to both illegal trafficking
and extortion, controlling also for structural (legal) motivations to deposit cash, as well as the need to
conceal proceeds from tax evasion. Using a panel of 91 Italian provinces observed over the period
2005-2008, we find that the average total size of money laundering is sizable, around 7% of GDP, 3/4
of which is due to illegal trafficking, while 1/4 is attributable to extortions. Furthermore, the incidence
of “dirty money” coming from illegal trafficking is higher in the Centre-North than in the South, while
the inverse is true for money laundering coming from extortions.

1. Introduction
Financial sector crimes are defined – in a broad sense – as any non-violent crime involving a
(regulated) financial institution which result in a financial loss because of fraud or
embezzlement (e.g., IMF, 2001; FBI, 2011). Financial institutions can be involved in such
crimes as victims, as perpetrators, or just as instrumentality. Check and credit card frauds are
examples of crimes for which financial institutions are victims. The sale of fraudulent
financial products is an example of crimes for which financial institutions are perpetrators.
Money laundering is the most important example of the third type of crime. Money
laundering is defined by the U.S. Department of Justice as “the process by which criminals
conceal or disguise the proceeds of their crimes or convert those proceeds into goods and services. It
allows criminals to infuse their illegal money into the stream of commerce, thus corrupting
financial institutions and the money supply, thereby giving criminals unwarranted economic
power” (FBI, 2011). According to estimates provided by the Financial Action Task Force
(FATF) – an intergovernmental body created in 1989 by the G7 to fight money laundering
and terrorism financing – criminal proceedings laundered via the international financial
system could reach about 2% of global GDP (IMF, 2001), posing a serious problem to
governments.
The standard approach followed by regulators to face the problem has been proposed by the
FATF in its Forty Recommendations – which significantly overlap with the Basel Core
Principle for Banking Supervision – and has been recognized by the Wolfsberg Group in a selfregulation initiative involving eleven large international banks. The cornerstone of the
approach is the “Know-Your-Customer” (KYC) rule, i.e., the need for financial and banking
systems to be transparent: every transaction within the system need to be traced to an
identifiable individual (e.g., IMF, 2001). The KYC rule is, however, subject to severe
limitations. Sharman (2010) suggests for instance the possibility to set up anonymous shell
companies, which can then be used to set up anonymous bank accounts 1. This is easier to be
done in tax havens which offer corporate and banking secrecy (Hines, 2010). Most of the tax
havens are indeed included also in the list of non-cooperative countries and territories (NCCT)
by the FATF.
Findley et al. (2012) show that “international rules that those forming shell companies must collect proof of
customers’ identity are ineffective”.

However, an important issue – which has been somewhat overlooked in regulation initiatives
so far – is that criminal proceedings that need to be laundered are usually represented by
cash. As is well known, cash is different from other payment instruments in that it guarantees
anonymity: notes pass from hand to hand without being traceable, reducing the degree of
transparency of the financial and banking systems (e.g., Payments Council, 2010). But
despite this, and despite the costs of managing the cash cycle are high for banks (e.g., because
they need to refill ATMs networks), cash is still largely used in the world economy. In
Europe, for instance, the euro cash-in circulation has doubled since euro coins and notes
became legal tender in 2002, even if this measure excludes the high-denomination banknotes
that are most commonly hoarded (e.g., Capgemini and Royal Bank of Scotland, 2011).
How much of the cash deposited via a regulated financial institution can be traced back to
criminal activities? In this paper we try – for the first time – to provide an answer to this
important question, first developing a new approach to measure money laundering, and then
proposing an application to Italy, a country where cash is still widely used, non-cash
payment methods are not well developed, criminal activities generate significant cash
proceeds that needs to be laundered, but also the underground economy contribute to
increase the demand for cash that is then fed back into the financial system (e.g., Ardizzi et
al., 2013). The new methodology proposed here is based on the flows of cash pumped into the
financial system, and will thus provide a (lower bound) estimate of the amount of money
laundered at its very early stage. Still, this represents a significant improvement with respect
to available estimates, which – instead of being based on econometric models using observed
data – are almost exclusively derived from data generated by the calibration of theoretical
models (e.g., Barone and Masciandaro, 2011, and Argentiero et al., 2008, for Italy).
The remainder of the paper is structured as follows. In Section 2 we define a new approach for
measuring money laundering: we present our methodology – based on the specification of an
econometric model of demand for cash deposits – and formulate testable hypotheses. In
particular, we distinguish the “dirty money” component of the flows of cash deposited in
current (bank and postal) accounts from the legal and the shadow economy proceeds, and
then discuss the variables affecting each of these three components. In Section 3 we first
discuss the estimates of the model controlling for alternative sources of the demand for cash
deposits, and then provide estimates of the size of money laundering at the national level, and
3
split them up to each Italian province. We also test the robustness of our findings to a
different model specification, which account for unobserved heterogeneity across provinces.
Finally, after a brief summary, some policy implications for contrasting money laundering
are discussed in Section 4.
2. Estimating money laundering via flows of cash deposited on current accounts: methodology
and theoretical insights
2.1. Cash deposits are observable, money laundering is not
Money laundering is a relatively easy to define concept from a theoretical point of view: it is a
criminal offense which originates from other underlying criminal activities, that amplifies in a
cumulative way the impact of crime on both regular and irregular economies. More
specifically, money laundering is the process by which income stemming from crime is
“cleaned up” through the legal channel (e.g., via bank transactions); once “cleaned up”,
money can then be reinvested in legal activities. Following Schneider and Windischbauer
(2008), this process can be summarized in three main stages:
a)
PLACEMENT:
«ill-gotten gains from punishable pre-actions are infiltrated into the financial
system; at this junction there is an increased risk of being revealed»;
b)
LAYERING:
«criminals attempt to conceal the source of illegal income through a great deal
of transactions by moving around black money. Transaction intensity and transaction
speed are increased withal (multiple transfer and transaction); electronic payment systems
plus diverging jurisdiction and inefficient cooperation of criminal prosecution often
simplify/facilitate the layering processes as well»;
c)
INTEGRATION:
«infiltration of transformed and transferred capital into formal economy
by means of financial investments (specific deposits, stocks) or property (direct
investment in real estates and companies) is primarily completed in countries promising
extraordinary short odds».
While the concept is relatively easy to define theoretically, the size and the empirical
relevance of money laundering is difficult to estimate, since the illicit money pumped into the
financial system cannot be observed directly. Exploring the scale and the impact on the
financial system of illicit funds is the goal of a rather new field of research, i.e. the so-called
economics of money laundering (e.g., Tanzi, 1997; Walker, 1999; Unger, 2007; Masciandaro et
4
al., 2007; Schneider and Windischbauer, 2008; Walker and Unger, 2009; Schneider, 2010).
There are two main limitations in the current literature: first, the type of predicate crimes
(i.e., the crimes whose proceeds are laundered) considered so far to estimate the size of money
laundering has been limited almost exclusively to narcotics trafficking (e.g., UNODC, 2011;
Barone and Masciandaro, 2011; IMF, 2001), while criminal organizations actually engage in a
number of other crimes. Second, and more important, to estimate the size of money
laundering most of the available studies consider data generated from the calibration of
theoretical models instead of actual data, which often muddle up the laundering activities
with the shadow economy, two linked but different phenomena (e.g., Argentiero et al., 2008).
The approach proposed here improves the accuracy of current estimates, starting from a very
simple idea, which basically extends the well-known Currency Demand Approach used to
estimate the size of shadow economy, another phenomenon that cannot be observed directly.
Money laundering is unobservable, but other variables necessarily related to money laundering
indeed are. And, among these, cash deposited via a regulated financial institution is probably
the most important. Hence, since cash in-flows are – at least partly – attributable to criminal
proceeds that need to be laundered, what one is required to do to estimate the size of money
laundering is to separate illegal proceeds from criminal activities from other determinants of
in-flows, including legal as well as illegal profits from tax evasion. In other words, one needs
to run a decomposition exercise, and identify the share of cash in-flows attributable to each of
their determinants.
Let INCASH be the ratio of the value of total cash in-flows on current (bank and postal)
accounts to the value of total non-cash in-flows credited to current (bank and postal) accounts.
This ratio basically represents the amount of non-traceable funds per euro of traceable ones.
In order to disentangle the “dirty money” component of these cash in-flows, one needs to
identify proxy variables for the amount of cash originated by criminal activities (call these
Z), and to control for alternative sources of cash in-flows linked to both legal activities and
proceeds from the underground economy (call these control variables X). One can then
assume a linear relationship between INCASH, X and Z, with conditionally independent
errors E(εit|Z it, X it) = 0, and run a regression model like the following Equation [1]:
INCASH it = α0 + ∑ αk X it + ∑ αh Z it + ε it
k
h
5
[1]
from which to estimate the size of INCASH due to factors Z. The main issue is therefore to
identify variables to be included in X and Z, which is what we do next.
Before moving further, notice that, considering cash in-flows on current (bank and postal)
accounts, our estimation strategy will cover only step (a) – the PLACEMENT – in the process of
money laundering. Moreover, notice that our estimates of “dirty money” can be interpreted
as a lower bound of the whole volume of money laundered within a country. In fact, illegal
money directly converted into other assets (such as real estates, diamonds, gold and vehicles)
are not considered here, since the focus is specifically on the role played by regulated financial
institutions. Finally, we do not consider illegal cash brought to an alternative remittance
provider for the placement outside of the banking system (e.g., “money-transfers” agents).
However, notice that since bank money is essential to transform capital into profitable
investments in the global formal economy, it is reasonable to assume that a relevant share of
illegal funds placed outside the banking system will be subsequently deposited in cash on a
bank account.
2.2. Proxying the “dirty money” component of the demand for cash deposits
Proxying the “dirty money” component of the cash in-flows requires to preliminary define
the criminal activities that generate illegal profits to be cleaned up, and then to select the
variables aimed at capturing their diffusion at the provincial level. As for the definition of
criminal activities, we rely on the distinction originally proposed by Block (1980) – well
established in the literature on organized crime – between “enterprise syndicate” and “power
syndicate”. The former concept refers to criminal groups running illegal economic activities
such as drug trafficking, smuggling, and prostitution, while the latter refers to organized
crime structures involved in the social, economic and military control of a specific territory.
Such a distinction is crucial for instance in Italy, where organized crime has “headquarters”
predominantly localized in the South, while the “retail markets” for goods and services (such
as drug and prostitution) prove to be more lucrative in the richest Centre-North regions of the
country (Ardizzi et al., 2013).
The relative presence of “power syndicate” (POWER) at the provincial level is measured by
the number of detected crimes from extortions within the province (normalized by its sample
mean value). The choice to focus on extortions is motivated by the fact that this is the main
6
way through which criminal organizations gain the control of territory at the local level. For
instance, Gambetta (1993) points out that the Sicilian Mafia uses extortion as «an industry
which produces, promotes, and sells private protection», and Alexeev et al. (2004) argue that
the payments extorted by organized crime can be viewed as additional “taxation” imposed to
firms. The request for protection is made regardless of the will of citizens, and using
Gambetta’s words «whether one wants or not, one gets it and is required to pay for it». The
same argument applies to the other Italian regions traditionally dominated by powerful
criminal organizations, such as the Camorra in Campania, the ‘Ndrangheta in Calabria, and
the Sacra Corona Unita in Puglia 2.
The relative diffusion of “enterprise syndicate” (ENTERPRISE) in a province is measured
by the number of detected crimes from drug dealing, prostitution and receiving stolen within
the province (normalized by its sample mean value). Such a proxy is able to account for those
illegal services provided on the basis of a mutual agreement, as well as those imposed with the
use of violence. Indeed, drug- and prostitution-related offenses – in line with the OECD
(2002) definition of illegal economy – imply an exchange between a seller and a buyer based
on a mutual agreement. On other hand, receiving stolen are based on the use of violence made
to persons or properties, and then imply “payments” which do not follow an “agreement”
between the thief, for instance, and the victim. We believe that accounting for both types of
offences is important in our model since both activities generate proceeds to be cleaned up.
Both the variables ENTERPRISE and POWER are weighted by a GDP concentration
index. Such a standardization allows us to better compare provinces characterized by
remarkable differences in the level of socio-economic development and, perhaps, in the effort
of crime detection and contrasting, thus avoiding attaching automatically higher levels of
crime and money laundering to provinces with a number of detected offences above the
sample mean. Both indicators for the diffusion of criminal activities are expected to show
positive correlations with cash in-flows. Thus, we put forward our first and main testable
hypothesis:
H1: The higher the diffusion of crime, the larger is money laundering, hence the higher the demand
for cash deposits, ceteris paribus.

2.3. The role of legal motivations and the proceeds from the underground economy
In order to control for the determinants of INCASH other than money laundering, our model
includes a set of variables expected to capture the legal motivations of cash deposit demand,
as well as its component linked to proceeds from the underground economy, i.e., proceeds
from legal activities which are however hidden to Tax Authority in order to evade taxes. As
for the legal motivations, we introduce the following controls: the degree of local socioeconomic development; the interest rate on bank deposits; the diffusion of electronic payment
instruments in commercial transactions. As suggested by several studies on shadow economy
(e.g., Schneider and Enste, 2000; Schneider, 2011), per capita GDP has a negative expected
impact on the use of cash: the higher the average living standard, the lower is the use of cash
for payments, thus the lower should be the demand for cash deposits because the volume of
currency circulating at the local level is lower. The average income is highly correlated with
education level (both general education and “financial literacy”), and more education usually
leads to a lower use of cash, since more educated individuals show greater confidence in
alternative payment instruments (World Bank, 2005). Our first measure of socio-economic
development is per capita provincial GDP (YPC) and the related hypothesis to be tested is
the following:
H2: The higher the average per capita income of a province, the lower is the demand for cash
deposits, ceteris paribus.
We also consider the rate of unemployment at the provincial level (URATE) as a second
possible indicator for the level of economic development. In particular, to some extent this
variable reflects differences in income distribution (see, e.g., Brandolini et al., 2004), thus in
educational levels, and is expected to exert a positive impact on the use of cash for payments,
thus on the demand for cash deposits: for a given average value of per capita GDP, a higher
unemployment rate corresponds to an income distribution more concentrated in high-income
classes, with a larger share of low-income (and poorly educated) people relying on the use of
cash for their payments. We formulate then the following hypothesis:
H3: The higher the unemployment rate of a province, the higher is the demand for cash deposits,
ceteris paribus.
8
A further control is needed in order to capture the variability across provinces of the average
attitude towards the use of cash in transactions as an alternative to electronic means of
payment. Several studies (e.g., Drehmann and Goodhart, 2000; Goodhart and Krueger, 2001;
Schneider, 2009) emphasize the importance of the technology of payments, with a particular
reference to the supply of electronic instruments. In line with this literature, we account for
available technology of payments at the provincial level by including the variable ELECTRO
among the legal determinants of INCASH. This variable measures the ratio of the value of
transactions settled by electronic payments to the total number of current accounts. A higher
share of electronic transactions implies a lower general attitude of individuals towards the use
of cash and, as a consequence, a lower demand for cash deposits. Thus, the expected sign of
the ELECTRO coefficient is negative.
H4: The higher the diffusion of electronic payments in commercial transactions, the lower is the
demand for cash deposits, ceteris paribus.
Finally, we consider the interest rate on current deposits (INT) as a possible determinant of
the legal component of INCASH. Based on standard economic theory, the interest rate on
deposits is expected to have a positive effect on INCASH, via its role of opportunity cost of
holding non-interest bearing currency. Thus, due to the usual “speculative” motive, the
expected sign of INT should be positive. However, there exist at least four reasons why this
could not be the case. First, INCASH is defined by a share, which implies that a higher
interest rate could in principle impact proportionally both on its denominator and numerator,
leading to a null overall effect. Second, our model deals with cash in-flows rather than stock
of deposits, which implies an ambiguous effect of the interest rate 3. Furthermore, the years
covered by our estimations have been characterized by very low interest rates, which is likely
to have strongly mitigated the speculative motive (ECB, 2008). Finally, we notice that most
recent developments in innovative banking (i.e., internet banking) – which increased the
supply of products characterized by lower operational costs and higher interest rates with
respect to traditional banking – might even bring about a negative relationship between INT
and cash deposits. Given these considerations, the expected sign of the INT coefficient is a
priori unclear and we do not formulate any hypothesis on its sign.
For a more detailed discussion on recent trends of both flow and stock monetary aggregates in Italy, see
Ardizzi et al. (2013).

The indicators used for controlling cash in-flows linked to proceeds from the underground
economy at the provincial level are the importance of particular productive sectors in local
economies, and the diffusion of tax frauds in sales by commercial retailers. The composition
of local production by economic sectors has been found to significantly affect the size of the
shadow economy (e.g., Johnson et al., 2000). Employment shares in agriculture (EMP_AGR)
and the construction industry (EMP_CON) are variables traditionally used as proxies for the
evasion of income tax and social security contributions, being these the typical sectors with a
higher presence of irregular workers (e.g., Torgler and Schneider, 2009; Capasso and Jappelli,
2011). As for Italy, according to the recent estimates provided by ISTAT (2010), irregular
workers were 12.2% of total employment in 2009, and the phenomenon was particularly
concentrated precisely in the agricultural (24.5% of irregular workers) and construction
sectors (10.5%). Thus, we formulate the following hypothesis:
H5: The larger the employment in the agricultural and the construction sectors, the higher is the
number of irregular workers and the demand for cash deposits due to proceeds from the underground
economy, ceteris paribus.
Finally, we include in our model a variable controlling for irregularities detected by the
Guardia di Finanza (the Italian Tax Police) through tax inspections at retailers.
COMM_FRAUDS is given by the ratio of the number of positive audits on cash registers and
tax receipts to the number of existing POS in the province. The standardization for the
number of POS is made necessary by the high variability in the presence of POS across
provinces, which is likely to affect the opportunity to evade (lower where the number of POS
is higher, see Ardizzi et al., 2013). This ratio is weighted by a GDP concentration index for the
same reason discussed above for crime variables. Our working hypothesis is then:
H6: The higher the diffusion of commercial tax frauds, the higher is the demand for cash deposits
due to shadow economic proceeds, ceteris paribus.
2.4. Assessing the size of money laundering
Equation [2] provides the complete model of the demand for cash deposits to be estimated,
which indentify cash in-flows to be laundered, controlling for the role of legal (or structural)
motivations and the proceeds from the shadow economy:
10
INCASH it = α 0 + α1YPCit + α 2URATEit + α3 ELECTROit + α 4 INTit + α5 EMP _ AGRit +
α 6 EMP _ CON it + α 7 COMM _ FRAUDS it + α8 ENTERPRISEit + α9 POWERit + ε it
[2]
In analogy with the reinterpretation of the Currency Demand Approach proposed in Ardizzi
et al. (2013) to estimate the magnitude of the underground economy, the size of money
laundering is assessed here by estimating the “excess demand” for cash deposits unexplained
by structural factors and business activities carried out in the underground sector.4 This
“excess demand” is obtained as the difference between the fitted values of INCASH from the
full model [2] and the predicted values obtained from a restricted version of Equation [2],
where the coefficients of ENTERPRISE and POWER are set equal to zero. To evaluate
separately the size of the two components of “dirty money”, we then proceed in a similar
manner, by imposing alternatively the restrictions α8 = 0 and α9 = 0, and calculating the
excess demand for cash deposits due to criminal activities linked to illegal traffics and
extortions, respectively. Given our definition of INCASH, money laundering estimates
obtained with this procedure are expressed in relation to total deposits generated by
instruments other than cash. Thus, in order to have measures comparable with those
obtained in previous studies, we need to rescale our results and express them in terms of
provincial GDP.
In the light of the above discussion about the greater diffusion of POWER in the (relatively
poorer) Southern regions, we expect to find a higher incidence of this component of money
laundering in the South. On the other hand, given the ability of criminal organizations to
“export” illegal traffics in the richest areas of the country, where the demand for “goods and
services” such as drug and prostitution is presumably higher, we expect to find a larger size of
ENTERPRISE in the Centre-North. We then formulate this last hypothesis:
H7: The incidence of money laundering component due to ENTERPRISE is relatively higher in
the Centre-North, while the component due to POWER is relatively higher in the South.
4
Notice that, as remarked in Ardizzi et al. (2013), our reinterpretation of the CDA originally suggested by Tanzi
(1980, 1983) reduces the methodology to a decomposition exercise in the spirit of, e.g., Wagstaff et al. (2003),
hence avoiding problems of causality in the relationships among our dependent variable and the demand factors
included in model [1]. In this perspective, all our testable hypotheses H1-H6 discussed above should not be read
as causal effects but as simple correlations between INCASH and each regressor.

3. Econometric analysis
3.1. Data and estimation technique
The model of the demand for cash deposits described by Equation [2] is estimated using a
panel of 91 Italian provinces observed over the period 2005-2008. The units included in the
final dataset represent about 90% of all the Italian provinces (103), and are those for which
complete information were available for all the variables in Equation [1]. The Appendix
reports the definition and descriptive statistics (for the whole sample, as well as for the two
macro-areas, Centre-North and South, separately) and information about the different data
sources (see Tables A1 and A2).
As for the estimation technique, given the panel structure of our data and the marked
heterogeneity across units (as highlighted by the prevalence of the between component of
standard deviation for all the variables excepting INT, see Table A2), we preliminary check
for the presence of heteroskedasticity, contemporaneous cross-sectional correlation and
autocorrelation in the residuals. Ignoring heterogeneity and possible correlation of regression
disturbances over time and between subjects can lead to biased statistical inference (e.g.,
Cameron and Trivedi, 2005). However, while most recent studies provide heteroskedasticand autocorrelation consistent standard error, cross-sectional or “spatial” dependence in the
residuals is still often ignored, thus imposing an artificial and potentially biasing constraint
on empirical models. Indeed, relying on proper statistical tests, we found that all the three
phenomena are present in the error structure of our data 5. Therefore, in order to adjust the
standard errors appropriately, we perform a Prais-Winsten regression with Panel-Corrected
Standard Errors (PCSE). In particular, we specify that, within groups, there is first-order
autocorrelation and that the coefficient of the AR(1) process is specific to each group. 6
3.2. Estimates of the demand for cash deposits
Table 1 reports parameter estimates of Equation [2] according to three different specifications,
where only YPC (Model 1), or URATE (Model 2), or both (Model 3) are included as control
Specifically, we used the Wooldridge (2002) test for autocorrelation in panel data, the Greene (2000) test for
groupwise heteroskedasticity, and the Pesaran (2004) test for cross-sectional dependence in panel data. All the
results ara available on request from the authors.
6 More technical details on this estimator are discussed in Hoechle (2007) and in the original contributions by
Prais and Winsten (1954) – as for the problem of serially correlated residuals – and by Beck and Katz (1995) – as
for the problem of heteroskedastic and contemporaneously cross-sectionally correlated residuals.

All the models perform quite well in terms of fit (the Wald statistic is always significant at
the 1% level, and the R2 is above 0.90) and show coefficients that are statistically significant
and with signs consistent with our theoretical hypotheses H1-H6. 7

The only exception is the interest rate on bank deposits (INT), which shows no significant correlation or a
negative correlation with cash in-flows. The likely motivations for this evidence have been discussed in Section
2.3.

More precisely, our results confirm that the demand for cash deposits can be decomposed into
three types of drivers:
(1) a money laundering component [H1]: both the diffusion of illegal traffics (ENTERPRISE)
and of extortion activities (POWER) prove to be positively associated to the relative size
of cash in-flows.
(2) a structural (legal) component [H2-H3-H4]: the average per capita income (YPC) and the
diffusion of electronic payments (ELECTRO) are negatively correlated with cash in-flows,
while the unemployment rate (URATE) shows a positive correlation;
(3) a shadow economy component [H5-H6]: both the two proxies for the diffusion of irregular
workers (EMP_AGR and EMP_CON) and the variable controlling for the presence of
commercial tax frauds (COMM_FRAUDS) are positively associated with cash in-flows.
It is worth noticing that both indicators characterizing the local economy remain highly
significant when used jointly (Model 3). This supports our argument that the unemployment
rate captures an additional (distributional) dimension of socio-economic development besides
the average per capita income, which helps better control for the legal motivations of the
demand for cash deposits 8.
An interesting finding is highlighted by Table A3 and Figure A1 in the Appendix, which
report the average simulated contribution of each variable to the observed demand for cash
deposits (expressed in percentage of GDP and normalized to 100), by referring to the most
complete specification of Equation [2] (Model 3). The major (negative) role is played by the
level of per capita GDP, while all the other regressors account for a much lower share of the
demand for cash deposits. The predicted contributions also points to sensible differences
across macro-areas. In particular, the incidence of YPC decreases (in absolute value) from
160 in the Centre-North to only 34 in the South, becoming relatively more close to the share
of URATE (19), which is unsurprising given the greater relevance of unemployment in
southern regions. Furthermore, in accordance with our hypothesis H7, the ENTERPRISE
component of criminal activities shows a much higher incidence in the Centre-North than in
the South (26 vs. 12), while the inverse is observed for the share of POWER, although with a
less marked gap (6 vs. 7).

a Average values computed using the whole set of money laundering estimates related to the balanced panel of 91 Italian
provinces.
b Before computing average values, we discarded all the provinces showing an outlier estimate of the POWER and/or
the ENTERPRISE component in at least one year of the observed period. The 8 outliers were identified using the Hadi
(1992, 1994) method and mostly correspond to the provinces of the biggest towns in Centre-North Italy.
3.3. Estimating the size of money laundering
The size of money laundering for each province in each year has been assessed relying on the
three model specifications discussed above, computing separate measures for the
ENTERPRISE and POWER components. Table 2 shows the average values – for Italy and
for the two sub-samples of provinces located in the Centre-North and in the South – obtained
using the whole set of money laundering estimates for the 91 provinces. Averages are also
computed dropping 8 outlier provinces identified applying the Hadi (1992, 1994) method with
15
respect to the two components jointly considered. Notice that outliers mostly correspond to
the provinces with the biggest (and the richest) towns in the Centre-North – like Rome, Milan
and Turin – and are mainly driven by the ENTERPRISE component, thus confirming the
polarization of illegal trafficking in the areas of the country where the “retail markets” for
goods and services such as drug, prostitution and receiving stolen are more lucrative (Ardizzi
et al., 2013).
Several interesting results emerge looking at Table 2. First, the estimated size of total money
laundering ranges from 6.6% of GDP with Model 3 to around 8% when using the restricted
specifications of Equation [2] that include only one indicator for the degree of socio-economic
development (YPC in Model 1 and URATE in Model 2). This evidence points out that not
accounting for the different features of the local economies (i.e., average per capita income
and its distribution across the population), one could mistakenly attribute to money
laundering a part of cash in-flows linked to other motivations.
Second, in all models the national level estimates highlight that the major role in determining
the relative size of money laundering is played by the ENTERPRISE component of criminal
activities. In particular, according to the most complete specification of cash deposit demand
(Model 3), about 3/4 of dirty money is attributable to illegal trafficking (5%), while 1/4 is due
to POWER (1.6%). However, looking at the estimates disaggregated at the macro-area level,
there are remarkable differences between Centre-Northern and Southern provinces in terms
of both the whole size of money laundering and the relative contributions of the two types of
criminal activities. More precisely, the share of dirty money on GDP is 7.1% in the CentreNorth against 5.4% in the South; as for the incidence of ENTERPRISE and POWER, the
former in Centre-Northern provinces is about 1.7 times higher than in Southern ones (5.7%
vs. 3.3%), while the inverse is true for money laundering coming from extortion activities, for
which the share in the South is 1.5 times the value of the Centre-North (2.1% vs. 1.4%). This
provides further support to our argument in hypothesis H7 of a greater incidence of illegal
trafficking proceeds in the richest areas of the countries and of proceeds from the direct
control of the territory through the power in the regions traditionally dominated by the big
criminal organizations, such as Mafia, Camorra, ‘Ndrangheta, and Sacra Corona Unita. This
picture emerges also from Figure 1, which shows the geographical distribution of the size of
16
money laundering by province, considering the aggregate TOTAL size and distinguishing
ENTERPRISE from POWER.
Figure 1 also points to the marked variability across provinces within the two macro-areas,
which embrace situations with very low values (white zones) and cases with very high values
(dark gray zones). This is particularly evident for the distribution of the ENTERPRISE
component in the Centre-North, where it clearly emerges the polarization of the phenomenon
in some provinces, including the biggest towns such ad Milan, Turin, Genoa, Bologna and
Rome. This helps explain why considering the average values obtained on 83 provinces, i.e.,
by discarding the estimates with outlier values for ENTERPRISE and POWER shares, the
overall size of money laundering decreases significantly (from 6.6% to 5.1% in Model 3) and
also the gap between macro-areas tends to disappear, mainly as a consequence of the lower
incidence of the ENTERPRISE component in the Centre-North (which reduces to 4%).

3.4. Robustness analysis
As a robustness check for our findings, we re-estimate Equation [2] using a Tobit Random
Effects specification (Tobit RE), in order to explicitly account for unobserved residual
heterogeneity across provinces. This model has the advantage – as compared to a standard
panel regression with random effects – to accommodate for the particular distribution of our
dependent variable, which is censored at zero and can assume only positive values 9. In
particular, we specify the error structure of Equation [1] as εit = ui + eit, where u and e are
individual effects and the standard disturbance term, respectively.
Coefficient estimates from Model 3 are reported in Table 3, while Table 4 shows the size of
money laundering estimated from the same model. The results are consistent with those
discussed in the previous section, confirming all our hypotheses H1-H7. More precisely, the
average total size of money laundering is around 7% if computed using the whole set of
estimates related to 91 provinces, and reduces to 5.7% for the restricted sample of 83
provinces which excludes outlier values of ENTERPRISE and POWER. We find again a
major role played by ENTERPRISE and a sensible gap between macro-areas, with the
provinces in the Centre-North showing a higher value (7.7% vs. 6%) due to the much
stronger incidence of the ENTERPRISE component (6.1% vs. 3.6%), while those in the
South exhibit a relatively higher share for POWER (2.4 vs. 1.6%). Finally, Figure 2 confirms
the marked variability across provinces within each macro-area, as well as the polarization of
money laundering in certain provinces, which is particularly evident for the values of
ENTERPRISE related to the biggest (and richest) towns in the Centre-North.
See, e.g., Wooldridge (2002). Notice that the theoretical distribution of INCASH is between 0, if all in-flows on
current accounts originate from payment means different from cash, to infinity, if all in-flows are made by cash.

4. Summary and policy conclusions
In this paper we provide a first attempt to estimate the size of money laundering using an
approach based on observed cash in-flows credited on (banking and postal) current accounts,
considering a panel of 91 Italian provinces over the period 2005 to 2008. Our econometric
results confirm that the demand for cash deposits is driven by three different components: (1)
a money laundering component: the diffusion of both illegal traffics and extortion activities
prove to be important drivers of cash in-flows; (2) a structural (legal) component: the average
per capita income and the diffusion of electronic payments are negatively associated with cash
in-flows, while unemployment rate shows a positive correlation; (3) a component stemming
from the underground economy: the presence of irregular workers and of commercial tax frauds
is positively correlated with cash in-flows.
Starting from these findings, the estimated relative size of money laundering at the national
level ranges from 6.6% of GDP to around 8%. Splitting the provinces between macro-areas,
we find that the share of “dirty money” on GDP is 7.1% in the Centre-North against 5.4% in
the South. When we consider ENTERPRISE and POWER separately, our results indicate
22
that the sources of “dirty money” differ across areas: proceedings to be laundered coming
from illegal traffics are about 1.7 times higher in Centre-Northern provinces than in Southern
ones (5.7% versus 3.3%); the inverse is true for proceedings from extortions, for which the
share in the South is 1.5 times the value of the Centre-North (2.1% versus 1.4%). This
evidence is coherent with the presence of a direct control of local territories in the South by
the big criminal organizations (Mafia, Camorra, ‘Ndrangheta, and Sacra Corona Unita), and
the ability of these criminal organizations to exploit richer retail markets in the CentreNorth.
What type of policy conclusions can we draw from these results? The amount of money
laundering in the Italian provinces is sizeable and this should be one of major policy concern
for governments, since Italy is not among the non-cooperative countries and territories
identified by the FATF, and it is certainly not a tax haven allowing to set up anonymous
companies. Hence, it is likely that criminal organizations are able to circumvent the KYC
rule, even in the presence of a strict regulation. Our approach here suggests that criminal
organizations provides a sizeable amount of cash proceeds which are whitewashed via the
regulated financial and banking system. Hence, an alternative strategy to fight this crime
with respect to transparency rules would be to reduce the attractiveness of untraceable means
of payments. Limiting the use of cash in transactions would not only be beneficial to improve
the efficiency of the payments system, but also to combat crime.

Appendix. Definition, descriptive statistics and contribution of the different variables included in the
equation [1] of cash deposit demand
This study uses a balanced panel of Italian provinces over the period 2005-2008. The dataset merges
information of four different sources: Bank of Italy (BdI), Guardia di Finanza (the Italian Tax Police,
GdF), Istat (the National Institute of Statistics), and Eurostat (the European Institute of Statistics).
All monetary variables are provided by BdI. Data on the provincial GDP and unemployment rate are
provided by Eurostat and Istat, respectively. The variables used as proxies for the diffusion of
commercial tax frauds and irregular work are computed on the basis of information provided by GdF
and Istat. Finally, the indexes of crime diffusion are computed using data on criminal offences
available from Istat website http://giustiziaincifre.istat.it. Complete information for all the variables
are available for 91 Italian provinces (out of a total of 103).
