Overcoming the challenges of informal economic activity requires a combination of policies
tailored to economy-specific circumstances. In countries where informality is predominantly a
reflection of poor governance, an appropriate policy package could streamline regulatory and
tax frameworks while improving the efficiency of public revenue collection and regulatory
enforcement as well as strengthening public service delivery to bolster tax morale. In countries
where informality is predominantly a reflection of underdevelopment, an appropriate policy
package could include measures to expand access to finance, markets, and inputs to foster firm
productivity and growth; better education to facilitate formal sector employment; and
enhanced safety nets to cushion household risks. Several such policy improvements have been
associated with sustained declines in informality.
Introduction
Widespread informality is a common policy challenge in emerging market and
developing economies (EMDEs). Theoretical models present two major reasons for the
emergence of informal economic activity: lack of development (Harris and Todaro 1970;
Loayza 2016) and poor governance (de Soto 1989). These two reasons suggest different
policy approaches to address informality. The former refers to factors such as an inability
of an urban, modern, formal sector to absorb rural migrants; limited financial
development to provide finance for formal sectors; and insufficient human capital that
prevents workers from finding jobs in the formal sector.
1
The latter refers to factors such
as excessively burdensome tax and regulatory frameworks that encourage firms to remain
informal, excessive labor regulations that increase the cost of formal employment, and
poor governance and regulatory quality that discourage formal participation (chapter 2).
The former reason emphasizes the inability to benefit from participating in the formal
sector, whereas the latter emphasizes the costs associated with formal-sector
participation.
2
Many EMDE governments have implemented a wide range of policy reforms in the past
few decades that may have helped to reduce informality (figure 6.1; Jessen and Kluve
2021).

These reforms have often been implemented to either increase the benefits of

formal-sector participation or reduce the costs of formal activity. For instance, both
corporate and personal income tax rates in EMDEs have been reduced, from 37-39
percent on average in the early 1990s to about 24 percent in 2019 (Végh and Vuletin
2015). Time spent on paying taxes was cut by about one-third in EMDEs between 2006
and 2020. Value added taxes, which can lower tax burdens through a refund on input
taxes, had been adopted in 71 EMDEs by 2020 (World Bank 2020a). Access to
financial services has broadened, with access to automatic teller machines (ATMs) per
100,000 adults and the share of the population with an account at a financial institution
both increasing by more than 50 percent between 2010 and 2018. Over the same
period, one-third to two-thirds of EMDEs improved their governance and institutional
quality.
A review of past policy reforms indicates that some reforms had unintended
consequences for informality. Policy reforms often had more benign effects on
informality when they were implemented in a supportive institutional and
macroeconomic environment. For instance, trade liberalization programs were often
associated with greater informality in the short term—unless they were accompanied by
greater labor market flexibility and an upgrading of skills in the labor force (Goldberg
and Pavcnik 2003; McCaig and Pavcnik 2015; World Bank 2019b).
The current pandemic has provided a reminder of the developmental challenges posed
by the informal sector. Informal participants have suffered more adverse economic and
health consequences from COVID-19 (coronavirus) than their formal counterparts (box
2.1). The untapped potential of informal sectors, if harnessed to boost income growth
and resilience, can help EMDEs build back better from the severe global recession of
2020. This is especially important against the backdrop of a steady decline in potential
growth, the growth an economy can sustain at full employment and capacity, over the
past decade as all fundamental drivers of growth weakened (World Bank 2018a, 2020b).
Specifically, this chapter addresses the following questions:
Which fiscal measures can help reduce informality?
Which other policies can help reduce informality?
What should be the elements of a comprehensive policy package to tackle
informality?
Contributions. The chapter makes the following contributions to the literature. First, it
offers a systematic review of policies that could affect informality, ranging from fiscal
policies to labor market regulations and policies to encourage financial development. It
covers both policies that are intentionally designed to encourage formalization and ones
that could incidentally affect the informal sector.
Second, the chapter describes novel empirical estimates of the cumulative changes in
informality following various policy changes, obtained using a local projection model.
Policy-related variables examined include tax rates, access to credit by the private sector,

Financial development reduces the costs of accessing external financing and thus
incentivizes firms and households to invest, including in higher-productivity projects.
It also incentivizes participants of the informal sector to join the formal sector. In
emerging market and developing economies (EMDEs) with above-median
informality, a significantly larger share of firms relies on internal finance and
identifies access to finance as a major business obstacle than in EMDEs with below-
median informality. Also, in EMDEs with more prevalent informality, a significantly
smaller share of households has access to commercial bank branches, automated teller
machines (ATMs), and credit. Over the past three decades, growing access to financial
services and credit has coincided with a falling share of the informal economy.
Introduction
In recent decades, much research has been devoted to understanding the
determinants of informal economic activity, including the role of financial
development (Loayza 2018; Ulyssea 2020). Financial development can influence
firms’ and individuals’ choices to engage in informal activity and may also,
conversely, be affected by the level of informality (for instance, Capasso and
Jappelli 2013; Elgin and Uras 2013; Straub 2005). Easier access to non-cash-
based payments—whether via mobile phones, cards, or online—can improve the
government’s ability to reach and support informal participants during a
recession like COVID-19 (World Bank 2019c).
a
Firms in the informal sector are typically characterized by small scale, low capital-
to-labor ratios, lack of investment, a low propensity to implement new and even
high-return technologies, and unskilled managers (Capasso and Jappelli 2013;
Dabla-Norris, Gradstein, and Inchauste 2008; Quintin 2008). By influencing
firms’ behavior, financial development can encourage capital accumulation and
productivity improvements, and thus enhance long-run economic growth,
particularly in the presence of informality (Antunes and Cavalcanti 2007).
Against this background, this box addresses the following questions:
What links between informality and financial development have been
identified by the literature?
How does financial development differ between EMDEs with high and low
informality?
How has financial development in EMDEs evolved?

BOX 6.1 Financial development and the informal economy
(continued)
The box examines the nexus between financial development and informality both
theoretically and empirically. It first provides a short literature review on the
channels through which limited financial development can encourage
informality, followed by a summary of existing empirical evidence. It then uses
both descriptive statistics and regression analysis to show that greater informality
is associated with less financial development, and that better access to finance is
associated with lower informality. The conclusion offers policy recom-
mendations.
Lessons from the literature
Theoretical models suggest that financial development reduces informality,
whereas the existence of informality could also hinder financial development.
Such theoretical findings are supported by empirical studies.
Theoretical models. As informal participants hide all or part of their income and
wealth from the authorities, they face high costs of providing collateral or
signaling their profitability to lenders and are often credit-rationed (Blackburn,
Bose, and Capasso 2012; Capasso and Jappelli 2013). The choice of operating
formally or informally thus involves a trade-off between higher financial costs, as
well as restricted access to public goods, and the benefits of lower tax and
regulatory burdens (Franjo, Pouokam, and Turino 2020; Straub 2005). This
trade-off can be faced at the level of the firm or household (extensive margin) or
at the level of individual transactions within a firm (intensive margin).
Theory predicts that, as financial markets develop, the size of the informal sector
will decrease. Financial development, which involves innovations ranging from
the emergence of new and more efficient monitoring and screening technologies
to more intermediated funds, typically reduces the average costs of accessing
financial resources and incentivizes firms and entrepreneurs to operate formally.
Several mechanisms have been explored.
Lower collateral requirements. By improving screening and monitoring
technologies, financial development will tend to reduce the minimum
collateral required for borrowing, which will tend to attract entrepreneurs
into the formal sector (Straub 2005).
Stronger legal enforcement. By strengthening financial contract enforceability,
financial development can lower credit costs, which will also tend to attract
entrepreneurs into the formal sector (Amaral and Quintin 2006; Antunes
and Cavalcanti 2007; Quintin 2008).
2
62 C H A P T E R 6 T
H E L O N G S H A D O W O F I N F O R M A L I T Y
Expanding pool of formal finance. By expanding the pool of formal-sector
funding, financial development can lower the relative cost of formal finance
and attract entrepreneurs into the formal sector (Blackburn, Bose, and
Capasso 2012; Capasso and Jappelli 2013).
More efficient tax auditing. Financial development can facilitate the
enforcement of tax compliance, which is likely to discourage informal
activity (Guo and Hung 2020).
Conversely, some studies point to informality as holding back financial
development, through several channels.
Tax evasion. Tax evasion, which is often at the core of informality, erodes
government revenue bases. Countries with pervasive tax evasion have often
used financial transaction taxes to boost revenues. These taxes increase
financial intermediation costs and may slow financial development (Elgin
and Uras 2013; Roubini and Sala-i-Martin 1992, 1995).
Higher bank monitoring costs. Where informality is prevalent, the lack of
formal, declared incomes and assets may force banks to incur higher
screening and monitoring expenses. This raises borrowing costs (Capasso,
Monferrà, and Sampagnaro 2015).
Empirical evidence. Several measures of financial development have been found
to be statistically significantly associated with smaller informal activity
(Bittencourt, Gupta, and Stander 2014; Bose, Capasso, and Wurm 2012; Gatti
and Honorati 2008). The empirical association has been robust to different
model specifications and estimation methodologies (See table 6B.1 for a detailed
summary).
Firm-level evidence. Firms that rate financing as a major obstacle to their
businesses have, on average, a 16 percent probability of hiding at least 50
percent of their sales, whereas this probability drops below 6 percent for
firms that consider financing to be a minor obstacle (Dabla-Norris,
Gradstain, and Inchauste 2008). More tax-compliant firms have reported
significantly easier access to credit, and this relationship was stronger in more
formalized economies (Gatti and Honorati 2008).
Household-level evidence. Italian households reported greater informal activi-
ty, especially in the construction sector, in regions with weaker financial
development (Capasso and Jappelli 2013).
Cross-economy evidence. Among 137 economies during 1995-2007, both
greater efficiency and depth of the banking sector were associated with

significantly lower informality (Bose, Capasso, and Wurm 2012). Among
150 economies during 1980-2009, faster broad money growth and a smaller
differential between lending and deposit interest rates were associated with
statistically significantly smaller informal economies, even when controlling
for institutional quality and central bank independence (Bittencourt, Gupta,
and Stander 2014).
b
Stylized facts
Firms and workers in the informal sector have less access to credit and financial
services in EMDEs with above-median informality than in EMDEs with below-
median informality.
Methodology and data. A sample of 122 EMDEs for 1990-2018 (or the latest
available year) is split into those with above-median and below-median shares of
informality by output (as proxied by the dynamic general equilibrium model-
based share of informal output in official gross domestic product [GDP]) and
employment (proxied by the share of self-employment in total employment).
c
Financial development is proxied, first, by firmsreported access to bank credit
and capital markets, their difficulty in accessing credit, and the share of internal
finance used in investment. Second, at the household level, financial
development is proxied by the number of commercial bank branches, ATMs, and
bank credit as well as account ownership and reported use of mobile payment
services. Data are available from World Bank Enterprise Surveys, the World
Bank’s Global Financial Development Database, and the World Development
Indicators. In addition, the International Monetary Fund’s Financial
Development Index and its subcomponents are used as proxies for overall
financial development and for development in “financial institutions” and
“financial markets.”
d

EMDEs with above-median informality and those with below-median
b. Several studies have found nonlinear relationships between informality and financial development.
The impact of financial development on informality is greater in more financially developed economies or
when GDP exceeds a certain level (Canh and Thanh 2020; Gharleghi and Jahanshahi 2020) or may even
be inverse-U-shaped (Elgin and Uras 2013).
c. The results from output informality and employment informality are largely consistent. This box
mainly relies on results from output informality.
d. The “financial markets” development index captures access to, and depth and efficiency of, an
economy’s stock and debt markets, which is less relevant for informal participants in EMDEs. The
“financial institutions” development index measures how developed financial institutions are in terms of
their depth (size and liquidity), access (ability of individuals and companies to access financial services),
and efficiency (ability of institutions to provide financial services at low cost and with sustainable
revenues).

informality (grouped above) are tested for statistically significant differences.
There is no presumption of causality going either from financial development to
informality or vice versa.
Firms. Firms in the informal sector have reported more restricted access to credit
from the banking sector and capital markets, which limits their ability to invest,
including in productivity-enhancing new technologies (Capasso and Jappelli
2013; D’Erasmo 2016; Ferreira-Tiryaki 2008). In EMDEs with above-median
output informality, on average, 36 percent of firms identified access to finance as
a major constraint—about 9 percentage points more than in other EMDEs
(figure B6.1.1). Firms also rely more on internal finance for operating, starting,
or expanding firms in EMDEs with more pervasive informality (Farazi 2014).
On average in EMDEs with above-median informality, 75 percent of firms
depend on internal finance to invest and 19 percent of firms can use bank funds
to fulfill their investment needs, compared with 68 percent and 29 percent of
firms, respectively, on average in EMDEs with below-median informality.
Households. Households in EMDEs with below-median informality have access
to significantly more commercial bank branches, ATMs, and credit than those in
EMDEs with above-median informality (figure B6.1.1). About 50 percent of the
population in EMDEs with below-median informality owns an account at a
financial institution or recently used a mobile money service—about 17
percentage points more than in EMDEs with above-median informality.
Evolution of financial development and its implications
EMDE financial systems have deepened and financial access has broadened over
the past three decades. This has coincided with a steady decline in the shares of
informal output and employment.
Methodology. A local projection model is used to estimate the cumulative
changes in the share of informal output or informal employment over one to five
years following a shift in financial development (annex 6A). Two dimensions of
financial development that are particularly relevant for informal participants are
examined. The first is the ability of individuals and companies to access financial
services, which is proxied by the number of commercial bank branches per
100,000 adults. The second dimension, financial system depth, is proxied by
domestic credit to the private sector in percent of GDP (Svirydzenka 2016;
World Bank 2020c). The estimation controls for per capita GDP. The sample
covers 125 EMDEs over 1990-2018.

inancial development and informality in EMDEs
Firms and workers in EMDEs with more pervasive informality are more likely to be
financially constrained, less likely to obtain bank finance, and more likely to have
limited access to other financial services than those in EMDEs with less pervasive
informality. As a result, firms in EMDEs with more pervasive informality rely more on
internal financing.

Note: Data are from EMDEs and the period 1990-2018. Output informality is measured by DGE-based estimates on
informal output (in percent of official GDP). Employment informality is proxied by self-employment in percent of total
employment. In A-D, *** denotes that the group differences are not zero at 10 percent significance level. “High
informality” (“Low informality”) are EMDEs with above-median (below-median) DGE-based informal output measure
(or employment informality proxied by self-employment shares) over the period 2000-18 (2010-2018 in C-D). ATM =

A.B. Bars are simple group means using data from latest year available for EMDEs with “high informality” and those
with “low informality.” “Finance constraint” measures the percent of firms identifying access to finance as a major
constraint in an economy. “Bank finance” measures the percent of firms using banks to finance investment in an
economy. “Internal finance” measures the average share of investment financed internally using personal savings.
C.D. Bars are unweighted averages of various financial development indicators for EMDEs with “high informality”
and those with “low informality” over the period 2010-18. Output informality is used in C and employment informality

measures the number of ATMs per 100,000 adults. “Private credit” measures domestic credit to private sector in
percent of GDP. “FD index” is the financial development index from the International Monetary Fund, which measu-
res the overall level of financial development. “Account ownership” is the percentage of survey respondents (aged
15 or above) who report having an account (by themselves or together with someone else) at a bank or another
type of financial institution or report personally using a mobile money service in the past 12 months. “Internal finan-
cing” is captured by the percentage of respondents (aged 15 or above) who report saving or setting aside any
money in the past 12 months to start, operate, or expand a farm or business.

(continued)
North Africa, South Asia, and, more recently, Sub-Saharan Africa (chapter 5).
Measures to expand access to finance have included better personal property
registration to facilitate borrowing by informal firms (for example, Czech
Republic; World Bank 2012) and digital payment systems to encourage a shift
away from informal finance (World Bank 2017).
Overall, access to finance and and the size of financial institutions increased in
more than three-fifths of EMDEs over 2010-18 (figure B6.1.2). The number of
ATMs per 100,000 adults rose from 26 to 40, and the share of population with
an account at a financial institution increased from 33 to 51 percent (Svirydzenka
2016). Domestic credit to the private sector in EMDEs increased by more than 4
percentage points of GDP, on average, over the same period.
Changes in informality following financial development. Financial development
was associated with significant contractions in both output and employment
informality (figure B6.1.3; annex 6A). First, 10 more bank branches per 10,000
adults—about the difference between the averages for EMDEs with above-
median and below-median informality—were associated with a 0.1- to 0.3-
percentage-point decline in the share of informal output in the following one to
five years. The share of informal employment also declined statistically
significantly. Second, a 10-percentage-point-of-GDP increase in domestic credit
to the private sector was associated with a significant contraction in the shares of
output and employment informality in subsequent years.
e
Conclusion
Both theory and empirical evidence indicate that more advanced financial
development is associated with a smaller informal economy, although the
direction of causality remains a matter of debate and may run both ways.
Financial development is considerably weaker in countries with more pervasive
informality. Financial systems have deepened, and access to financial services has
broadened, in EMDEs over the past three decades.
Policy measures to reduce informality, however, need to go beyond improving
the financial system and facilitating access to credit. Evidence suggests that the
impact of financial development on informality depends on the quality of the
legal and regulatory systems, the level of economic development, and financial
e. The results remain broadly unchanged when levels of informal output and employment are used as
robustness checks (see figure 6A.1 for results using levels of informal output). The robust results suggest
that any movement in the informal share of output or employment is determined by changes in informal
activity (the numerator), not by only changes in formal activity (the denominator).

A.B. Bars (A) and lines (B) show simple EMDE averages for corresponding time periods. “Overall” is the aggregate
financial development index obtained from the IMF. It measures the overall level of financial development and
captures development in both “financial institutions” and “financial markets.” The latter is about the access, depth,

The “Institutions” index measures how developed financial institutions are in terms of their depth (size and liquidity),
access (ability of individuals and companies to access financial services), and efficiency (ability of institutions to
provide financial services at low cost and with sustainable revenues). Some of the subindicators for “Institutions” are
used in C-D to show the access (C) and depth (D) of financial institutions.

development itself. In addition, the effect of measures to promote financial
development may be temporary and differ depending on the structure of
financial markets.
In particular, improvements in the legal system may be a precondition for
achieving broader access to credit that can draw informal firms into the formal
sector. Measures to improve contract enforcement and investor protection may
be particularly effective in EMDEs, which often fall well behind best practices.
Greater competition and access to markets may foster the productivity gains that
are needed for firms to be able to service debt, one aspect of financial
development. The possibility of reverse causality suggests that, in some instances,
measures to reduce informality by streamlining regulations and improving their
enforcement may create a virtuous circle of lowering informality and spurring
financial development.

labor market efficiency, governance, and regulatory quality. This is the first study to
conduct such empirical analysis for a wide range of policies. It is also the first to examine
the share of informality in both economic output and employment: earlier studies have
tended to focus on either informal output, or informal employment, or informal firms.
4
Third, the chapter is the first published attempt to comprehensively examine the link
between financial development and informality both theoretically and empirically (box
6.1). It reviews the literature identifying the channels through which limited financial
development can discourage formalization. It uses both descriptive statistics and
regression approaches to show that informality is associated with lack of financial
development, and that improvements in access to finance are associated with declining
informality.
Main findings. First, macroeconomic policies, governance, and business climates have
become more conducive to lowering informality over the past three decades. Over that
period, EMDEs have reduced tax burdens, improved governance and regulatory quality,
and expanded access to finance, education, and public services.
Second, policies that seek to streamline tax regulation, strengthen tax administration,
and improve public service delivery have been associated with declines in informality.
Separately, policies aimed at invigorating private sector activity broadly, such as
measures to increase labor market flexibility, streamline regulatory frameworks for firm
start-up, expand access to finance, and improve governance have also been associated
with declines in informality.
Third, policy measures can have unintended consequences. For instance, trade
liberalization that raised competition in the tradable sector was sometimes associated
with greater informality in the short run, unless accompanied by measures that increase
labor market flexibility. Also, reductions in informality have tended to be greater for
reforms accompanied by business development and training programs, public awareness
campaigns, and stronger enforcement.
Fourth, financial development has been associated with declining informality (box 6.1).
It reduces the average costs of access to external financing and incentivizes firms to
invest in higher-productivity projects and to join the formal sector. Over the past three
decades, increased access to financial services and increased credit availability have been
followed by declining informality.
Fifth, a comprehensive policy package tailored to country circumstances offers the
greatest chance of success in reducing informality. A combination of measures to
strengthen economic development, boost productivity in both formal and informal
sectors, streamline regulations, and ensure effective enforcement can address multiple

sources of informality. The relative priorities will depend on the economy-specific
features of informality.
The rest of the chapter is organized as follows. It first presents a range of fiscal policy
options that may be used to help remove barriers to joining the formal sector. It then
discusses a wide range of policies that can ease the transition from the informal to the
formal sector. The chapter also illustrates the importance of having a comprehensive and
complementary policy package to tackle the challenges posed by informality and how to
implement it successfully. In addition, the chapter describes the implications of digital
technologies for coping with informality. The final section summarizes the conclusions.
Data and methodology
This chapter relies on the database detailed in chapter 2 for measures of output and
employment informality. It applies several statistical tests to quantify the links between a
wide range of policies and informality, without establishing or assuming causality. It
then estimates a series of local projection models to help quantify the cumulative
response of informality to various policy actions over the short and medium terms.
Data. Both output and employment informality are considered here. Output informality
is proxied by estimates based on the dynamic general equilibrium (DGE) model in
percent of official gross domestic product (GDP), and employment informality is
proxied by self-employment in percent of total employment. Both measures are available
for up to 121 EMDEs over the period 1990-2018.
5
For the local projection estimation,
all data series on informality are detrended using the Hodrick-Prescott filter to mitigate
concerns that the results are driven by the declining trend in informality (chapter 2). A
wide range of policy measures is considered here, ranging from changes in corporate tax
rates to actions to improve the ease of doing business (table 6B.2). Detailed data
descriptions are provided in annex 6A.
Empirical strategy. The chapter applies two empirical approaches to assess the links
between informality and policies.
First, differences between average policies in EMDEs with above-median and below-
median informality are tested for statistical significance. The sample of EMDEs is
grouped into those with an above-median share of informal output and those with a
below-median share of informal output, on average during (up to) 1990-2018.
6
For each
subsample, simple averages of policy indicators are generated and the difference between
these two group averages is tested for statistical significance. EMDEs with high
5
In the case of financial development, absolute levels of informal output and informal employment, rather than
their relative share of official GDP or total employment, are used as robustness checks when a local projection
model is estimated (figure 6A.1). Using absolute levels of informal output and informal employment avoids the
possibility that the results are driven by movements in total official GDP or total employment (the denominator)
rather than movements in output or employment in the informal sector (the numerator).
6
The results are the same when EMDEs are grouped according to employment informality (table 6B.3).

7
The results are robust to using self-employment as ameasure of employment informality (table 6B.5). As
further robustness checks, both ordinary least squares and quantile regressions are performed using the same set of
policy for both output and employment informality measures. The regression results are largely in line with the
findings from the group comparison approach (tables 6B.6-6B.7).
8
In contrast, EMDEs with high or low informality often do not differ significantly in their average statutory
rates for social security contributions nor their revenue collections from such taxes, but they do differ significantly in
the amount of social security they provide (see below).

i
nformality refer to EMDEs with below-median informality.
Second, a local projection model as in Jordà (2005), Teulings and Zubanov (2014), and
World Bank (2018a) is estimated to identify the effects of policy changes on informality
over time for a sample of up to 125 EMDEs during 1990-2018. The model estimates
the cumulative changes in informality after policy changes over different time horizons
while controlling for country fixed effects and per capita income levels (table 6B.4).
7
Policy changes are defined as a unit change in the corresponding policy indicator. For
instance, a 1-percentage-point increase in the personal income tax rate is considered a tax
policy change. Annex 6A details the model specification.
Fiscal measures
High tax rates or payments, complicated tax codes, and administrative burdens have
been commonly cited as reasons for informal activity (Auriol and Warlters 2005; Perry
et al. 2007; Waseem 2018). Lax tax enforcement facilitates poor tax compliance
(Slemrod 2019). Poor government services—often underfunded and inefficiently
delivered—will tend to erode tax morale (Awasthi and Engelschalk 2018). In a sweeping
survey of the literature, measures to address such issues have been identified as having
been particularly effective at encouraging a shift into formal activity (Jessen and Kluve
2021; World Bank 2019b).
Tax rates
Higher tax rates in more informal EMDEs. On average during 2010-2018, average
corporate and personal incomes tax rates were significantly higher, by 3 (corporate) to 4
(personal) percentage points in EMDEs with above-median output informality than in
those with below-median output informality. Value added tax (VAT) rates were also
statistically significantly higher in EMDEs with above-median output informality than
in those with below-median output informality.
8
Over time, shift away from income taxes. Since 1990, both corporate and personal
income tax rates have been lowered in EMDEs whereas the use of VAT has expanded.
Average corporate and personal income tax rates in EMDEs have fallen by 13 and 15
percentage points, respectively, from close to 40 percent in the beginning of the 1990s to
about 24 percent in 2020 (figure 6.2). About two-thirds of EMDEs lowered their
statutory personal income tax rates and more than three-quarters lowered their statutory

These efforts often coincided with a
streamlining of tax regulations and a broadening of the tax base (Kopczuk 2005).
Although income tax rates were lowered, often to reduce distortions that discourage
employment, VAT was introduced, which could be less distortionary than income tax
but may lead to a more regressive tax system (Cnossen 1998).
10
Many economies in
Latin America introduced VAT regimes in the 1970s and 1980s, and their ranks were
joined by a large number of economies in Europe and Central Asia (ECA) during the
1990s. Between 1990 and 2020, the number of EMDEs with VAT systems increased
from 29 to 91 (Végh and Vuletin 2015; World Bank 2020a).
Lower informality after tax rate cuts. Lower corporate or personal income tax rates can
reduce the incentives of firms and households to operate in the informal economy to
lower their costs. In one EMDE, for example, a tax hike in 2010 reduced the number of
formal firms and their sales revenues to such an extent that tax revenues three years after
the hike were lower than they would have been without the tax hike (Waseem 2018). A
sweeping review of past government interventions suggests that tax cuts were particularly
effective in reducing informality (Jessen and Kluve 2021). Similarly, a review of policies
showed that tax simplification and tax cuts were associated with lower informality
(World Bank 2019b).
Meanwhile, the introduction of VAT may strengthen incentives to register in order to
qualify for VAT refunds—or, conversely, may strengthen incentives to operate
informally to offer lower prices excluding VAT. A VAT regime imposes an input tax on
informal firms that do not qualify for refunds but source from formal firms, which in
the right circumstance can motivate them to register, thus raising government revenue
collection (de Paula and Scheinkman 2010; Loayza 2018; World Bank 2018c).
11
A
requirement to digitalize sales receipts for accelerated VAT refunds could further
strengthen incentives to register and correctly report sales (Fan et al. 2020). In one case,
electronic invoicing for VAT purposes was rolled out in waves between 2014 and 2018
and resulted in more than 5 percent higher reported firm sales, purchases, and value
added in the first year after adoption (Bellon et al. 2019).
Indeed, since 1990, a 10-percentage-point decrease in the corporate income tax rate has
been associated with a cumulative decline in output informality of about 0.1 percentage
point of GDP, relative to trend, over the following two years (figure 6.2).
A similarly
sized reduction in the personal income tax rate has been associated with a slightly
stronger, and deepening, fall in output informality in the following five years. Despite
finding significant falls in informality following tax cuts, these falls are generally small in
9
The sample contains up to 53 EMDEs for which data are available in 2020 and 1990.
10
That said, the presence of an informal economy could lead to incomplete coverage and inefficiencies in the
VAT system (Keen 2008; Piggott and Whalley 2001; Emran and Stigliz 2005). In some case, labor informality was
found to be associated with lower overall VAT collection (Caro and Sacchi 2021).
11
Poorer households tend to spend a larger share of their budgets in the informal sector than richer households.
As a result, households in the richest quintile can face an effective consumption tax rate that is twice that of the
poorest quintile (Bachas, Gadenne, and Jensen 2020).

In the case of employment informality, the average annual number of hours spent on complying with VAT
refund requirements amounted to 37 in EMDEs with above-median informality—20 hours per year significantly
more than in EMDEs with below-median informality (table 6B.3).
size, suggesting that cutting tax rates alone is not enough to move all participants from
t
he formal sector to the informal sector. Other policy measures are needed (Loayza
2018). Meanwhile, increases in VAT have not been associated with any significant
change in output informality. This suggests that some informal firms source their inputs
from informal markets that operate outside the VAT system. The results are robust to
using employment informality, instead of output informality.
Tax compliance
More burdensome tax compliance in more informal EMDEs. Beyond tax rates, tax
compliance can be costly and time-consuming and, thus, discourage formal registration
by firms, especially those with poor profitability (Morales and Medina 2016; Rocha,
Ulyssea, and Rachter 2018; Ulyssea 2018). On average, in EMDEs with above-median
informality during 2010-18, it took the average firm 33 hours longer and required
statistically significantly more payments, estimated at 11 per year, to comply with tax
regulations than in EMDEs with below-median informality (figure 6.3). As a result,
despite higher corporate and personal income tax rates in EMDEs with above-median
informality, revenue collections were lower: on average in EMDE with above-median
output informality, personal and corporate income tax revenues were statistically
significantly lower, by 0.6 and 0.8 percentage point of GDP, than in EMDEs with
below-median informality.
Similar administrative challenges have troubled the administration of VAT regimes in
countries with high informality. During 2016-18, firms spent 29 hours a year, on
average, complying with VAT refund requirements in EMDEs with above-median
informality—7 hours more than in EMDEs with below-median informality, though the
difference is not statistically significant.
12
It took about 40 weeks for firms in EMDEs
with above-median informality to receive VAT refunds—significantly longer than the
31 weeks in EMDEs with below-median informality.
Over time, less burdensome tax compliance. Firms’ tax compliance costs have declined
in EMDEs in the past few decades. Since 2006, the time spent by firms on paying taxes
has fallen by 68 hours a year, on average, in EMDEs and the average number of tax
payments per year has declined by one-third, to 26 payments per year in 2020 (figure
6.3). In ECA, the introduction of electronic tax filing and payment systems has reduced
the average tax filing time from 473 hours in 2006 to 225 hours in 2020 (World Bank
and PwC 2019).
Efforts to lower tax burdens have been among the most common policy reforms in
EMDEs, especially in East Asia and Pacific (EAP) and Latin America and the Caribbean
(LAC). Measures to make tax compliance less burdensome have ranged widely (Awasthi

were not followed by immediate declines in informality.

and Engelschalk 2018; Slemrod 2019). Tax bases have been simplified in industries with
a high percentage of undeclared workers (for example, domestic work), and tax
regulations have been harmonized across different types of firms (Oviedo, Thomas, and
Karakurum-Özdemir 2009). At the same time, tax enforcement has been stepped up by
expanding the use of information technology and communication tools, encouraging a
switch from cash-based transactions to bank-based ones, and strengthening the capacity
of tax administrations (for example, Nguimkeu and Okou 2019; Prichard et al. 2019).

Lower informality after measures to facilitate tax compliance. Measures to reduce the
burden of tax compliance or firm registration can lower the cost for informal firms of
moving into the formal sector (Rocha, Ulyssea, and Rachter 2018). Coordination of
minimum tax thresholds across different types of tax, such as personal income tax, VAT,
and social security contributions, could increase tax compliance and improve welfare
(Kanbur and Keen 2014). Measures to harmonize tax provisions or other regulations
across different types of firms can reduce incentives for firms to evade taxation and
remain small and informal (Dabla-Norris, Gradstein, and Inchauste 2018; Harju,
Matikka and Rouhanen 2019). Measures to strengthen tax administration can increase
the likelihood of detection of informal firms that do not comply with taxes (Carrillo,
Pomeranz, and Singhal 2017; Naritomi 2019).
Measures to facilitate tax compliance have been accompanied by statistically significant
declines in output informality (figure 6.3). The effects have not been immediate, being
insignificant in the first year, but have strengthened over time. Thus four years after
reforms that increased the score for the ease of paying taxes by 1 point, the share of
output informality was 0.1 percentage point of GDP lower—a statistically significant
difference.
Tax morale
Weaker tax morale in more informal economies. Tax morale is weaker in EMDEs with
above-median informality. On average, in EMDEs with above-median output
informality, the average household scores 2.5 points on a scale of 0 to 10, with 10
indicating that underreporting of income for tax purposes is always justifiable—that
score is 0.4 index points, and statistically significantly, higher than in EMDEs with
below-median informality (figure 6.4).
Among the many reasons for weaker tax morale is a lack of trust in the government or
dissatisfaction with the quality of public service delivery.
14
Indeed, entrepreneurs in
EMDEs with above-median output informality report significantly poorer access to
government support and programs as well as poorer physical and services infrastructure
than entrepreneurs in EMDEs with below-median output informality (figure 6.4;
chapter 4). Similarly, significantly better access to commercial and professional
infrastructure is reported by businesses in EMDEs with above-median tax morale than
those in EMDEs with below-median tax morale. Coverage of unemployment benefits is
significantly lower, by about 3 percentage points of the population, in EMDEs with
above-median informality than in those with below-median informality. On average , in
EMDEs with below-median informality, social insurance programs can cover about 34
percent of the annual income or consumption of the beneficiary household, which is
significantly lower, by 6 percentage points, than in EMDEs with above-median
informality.

See Daude, Gutiérrez, and Mulguizo (2012) for a review of drivers of tax morale. OECD (2019) suggests that
there is a positive association between tax morale and public service provision in Africa, whereas tax morale in Latin
America is more linked with trust in the government.

The indicator for tax morale is taken from World Values Surveys, conducted in various years. The current
round of World Values Surveys will complete its data collection in December 2021.
16
Transitions from an employment-based social security system to a well-designed model of risk sharing can
further improve the safety net for informal workers and help protect both formal and informal workers during
economic downturns (World Bank 2013, 2018c).
Education and health outcomes are significantly poorer in EMDEs with above-median
i
nformality, with Programme for International Student Assessment (PISA) test scores for
15-year-old students in EMDEs with above-median informality being lower by about 10
percent than in those with below-median informality, and life expectancy eight years
lower in EMDEs with above-median informality. The poorer outcomes are partly due to
more limited government expenditures on education and health in EMDEs with more
pervasive informality (chapter 4).
Over time, stable tax morale, despite better government services. In contrast to output
and employment informality, tax morale has remained stable over the past three decades.
In the early 1990s, households in EMDEs gave an average score of 2.5 to the
justifiability of cheating on taxes (where a score of 1 means that cheating on taxes is
never justifiable and 10 means that it is always justifiable)—virtually the same as in
2010.
15
As one of the social capital measures with deep roots in culture, tax morale is
slow-moving by nature (Luttmer and Singhal 2014). In contrast, entrepreneurs in
EMDEs have, on average, perceived statistically significant improvements in government
support or programs for small and medium enterprises (SMEs) and in improving
commercial and professional infrastructure available to SMEs (figure 6.5).
Meanwhile, actual government service delivery has improved by several measures. The
adequacy of social insurance programs has risen in EMDEs from an average of 31
percent of household income in the 2000s to 34 percent a decade later. Infrastructure—
for example, road kilometers, access to reliable power, and access to internet services
has improved considerably since 2000. Mobile cellular subscriptions rose from 28 to 95
per 100 people between the 2000s and the 2010s. EMDEs’ test scores on PISA
indicators of education outcomes have risen significantly, by 17 points, and life
expectancy has risen by four years, on average, in EMDEs.
A range of measures has been introduced over the past three decades to cultivate better
tax morale, including public appeals to declare activities, campaigns to encourage
a culture of commitment to declaration, and efforts to change perceptions of the tax
system’s fairness (Williams and Schneider 2016). Other measures have included steps to
shift the burden of payments of social security contributions from employers to
employees (for example, in Latvia, Poland, and Slovenia), to reduce employers’ social
security contributions (for example, in Bulgaria), and to link social benefits to personal
contributions (for example, in most of the economies in the European Union; Oviedo,
Thomas, and Karakurum-Özdemir 2009).
16
Lower informality after improvements in government services. Improvements in the
perception that tax dollars are spent judiciously—that is, for appropriate objectives and
in an efficient way—can encourage greater tax compliance and lessen informality (Sung,
C H A P T E R 6 2
79 T H E L O N G S H A D O W O F I N F O R M A L I T Y
Awasthi, and Lee 2017). Better education or infrastructure can help raise labor
productivity in both formal and informal activities, thus facilitating a move of previously
insufficiently productive, informal firms into the formal sector.

See, for instance, Benjamin and Mbaye (2012); Kim, Loayza, and Meza-Cuadra (2016); Oviedo, Thomas,
and Karakurum-Özdemir (2009); and World Bank (2018c). Better access to education or infrastructure may boost
productivity growth more in the formal sector than in the informal sector, resulting in a fall in the relative share of
informal output in total economic output.

Empirically, declines in output informality followed improvements in government
services, although the small country sample of data for tax morale blunts the significance
of coefficient estimates (figure 6.6). Measures perceived to improve government support
for SMEs by 1 standard deviation were followed by a 0.1-percentage-point decline in
the share of output informality five years later. A similar, 1-standard-deviation
improvement in SMEs’ access to quality commercial and professional infrastructure was
also followed by a 0.1-percentage-point decline in the informal output share after two
years, although the effect subsequently dissipated.
Other policies
Many reforms designed to invigorate private sector growth can also help lower
informality, such as reducing corruption, improving business climates and governance,
strengthening enforcement of taxes and regulations, and liberalizing labor and product
markets, including through trade liberalization.

Financial development, by lowering
financing costs, can incentivize firms to operate formally, and has often been associated
with a shrinking informal sector (box 6.1). Policy measures that narrow the earnings gap

Kuddo (2018) shows that about 60 percent of the reforms implemented between 2007 and 2017 throughout
the world aimed at improving labor market flexibility. Among measures to improve product market flexibility, trade
liberalization has been associated with increased informality unless complementary reforms improved labor market
flexibility (World Bank 2019b).

between informal and formal workers or reduce the labor productivity gap between
informal and formal firms, such as measures that improve access to education or training
programs, can also help reduce informal activity.
Labor market regulations
More restrictive regulations in more informal economies. Although higher minimum
wages may attract informal workers into the formal sector, they are also likely to
discourage firms from hiring workers, resulting in unclear effects on employment of
minimum wages (especially in the presence of imperfect competition).
19
In a
development context, in which agricultural sectors are large and urbanization is still
under way, a higher minimum wage can slow capital accumulation and push workers
into informal employment (Loayza 2016).
Empirically, labor market regulations in EMDEs with above-median informality are
more restrictive than in EMDEs with below-median informality (figure 6.7). Minimum
wages in EMDEs with above-median output informality average 5.5 percent of per
capita income, which is 1.3 percentage points, and significantly, higher than in EMDEs
with below-median output informality. Flexibility of working hours, often measured by
the inverse of restrictions on night and overtime work, holiday work, and the length of
the work week, is significantly less in EMDEs with above-median output informality
than in EMDEs with below-median output informality.
Over time, increased labor market flexibility. Labor market flexibility and efficiency
have increased in EMDEs over the past three decades (figure 6.7). EMDEs have lowered
their minimum wage by 0.6 percentage points of GDP per capita from its level in the
1990s (Loayza 2016). Between 2010 and 2018 alone, about one-quarter of EMDEs
increased their perceived labor market efficiency, which measures the extent to which
the labor market matches workers with the most suitable jobs for their skillset (WEF
2020). About 40 percent of EMDEs changed regulations to make the hiring and
dismissal of workers more flexibly determined by employers. During the same period, 4
out of 10 EMDEs reduced the costs of advance notice requirements, severance
payments, and the penalties due when dismissing a worker with a 10-year tenure.
These changes reflect several decades of labor market reforms especially in ECA, Sub-
Saharan Africa (SSA), and, more recently, LAC. Regulations with respect to hiring and
dismissal, working hours, and wage rates have been eased in ECA (EBRD 2018).
Incentives have been provided for worker registration—for example, legalization of
undocumented workers—while enforcement of existing labor laws has been tightened
(Anand and Khera 2016; Munkacsi and Saxegaard 2017). In EMDEs, the reduction of
19
The employment effects of minimum wages have been unclear (Manning 2021). An increase in the real
minimum wage has been associated with a lower probability of being hired in the formal sector, or employment in
general (Gindling and Terrell 2007; Maloney and Nuñez Mendez 2004). However, employment effect was not
found in studies like Hohberg and Lay (2015); Lemos (2009); and Urzua and Saltiel (forthcoming).
282 C H A P T E R 6 T
H E L O N G S H A D O W O F I N F O R M A L I T Y
minimum wages encouraged formalization of employment (Betcherman, Meltem
Daysal, and Pagés 2010; Kugler, Kugler, and Herrera-Prada 2017).
Lower informality after labor market reforms. Excessive labor market regulations, such
as excessively high minimum wages, can distort the labor market and provide incentives
for firms to hire workers informally (Kugler 2004; Loayza 2016; Ulyssea 2010).
Increases in labor market flexibility and efficiency have been associated with significant
falls in output informality (figure 6.8). A 1-standard-deviation increase in the Fraser
Institute’s index of hiring and firing regulation, which gauges the extent to which the
FIGURE 6.7 Labor market reforms and informality in EMDEs

Firm start-up costs
More difficult firm start-up in more informal economies. Starting a new firm is more
challenging in EMDEs with more pervasive informality (figure 6.9). On average, the
costs of business start-up amount to about 90 percent of per capita gross national income
(GNI) in EMDEs with above-median output informality—three times the level in other
EMDEs. It takes 33 days to start a business in EMDEs with above-median informality—
about 1 day longer than in other EMDEs, although the difference is not statistically
significant.
Over time, easier firm start-up. Business start-up costs have fallen steadily in EMDEs
over the past two decades. Between 2003 and 2018, the costs of business start-up fell

required to start a business declined by two-thirds, to 23 days. There has also been a
reduction in the number of procedures needed to start a business (World Bank 2020a).
Various regulations have been used to encourage formal firm start-up. “One-stop-shop”
registrations have been created (for example, in Ukraine) to simplify the firm start-up
process. Similar reforms have been carried out in several other EMDEs (World Bank
2009, 2010, 2011). EMDEs in ECA and SSA have implemented an above-average
number of reforms to reduce the costs of starting a business during the past decade.

Firm start-ups are more challenging in EMDEs with above-median informality than in those with

Lower informality after regulatory easing. Easier and less costly firm registration
reduces the costs for firms of entering the formal sector (Haltiwanger, Jarmin, and
Miranda 2013; Loayza 2018; Nguimkeu 2015). Empirically, a reduction in the costs of
business start-up by 10 percentage points of GNI per capita was associated with a
significant reduction in output informality, by 0.1 percentage point of GDP over the
following five years. Similarly, a one-day reduction in the number of days required to
start a business was associated with a significant contraction in output informality, by
0.4 percent point of GDP over the following two years.
Governance
Weaker governance in more informal economies. More corruption, less effective
government, and weaker law and order have been associated with larger informal sectors
in EMDEs (figure 6.10; chapter 4). On average in the past three decades, EMDEs with
above-median output informality scored significantly lower (by about half of a standard
deviation) on government effectiveness, control of corruption, and rule of law than
other EMDEs. Using the International Country Risk Guide (ICRG) indicators,
bureaucracy quality, control of corruption, and law and order in EMDEs with above-
median output informality are significantly lower, by 0.4-0.7 standard deviation, than in
EMDEs with below-median informality.
Over time, improved governance. Governance has generally improved in EMDEs since
1990. Both bureaucracy quality and law and order improved by 0.2-0.6 standard
deviation between 1990 and 2018. Control of corruption, law and order, and
bureaucracy quality strengthened in the early 1990s but weakened again in the second
half of the 1990s with the economic, social, and political disruptions in transition
economies, before stabilizing in the early 2000s.
To improve governance and regulatory quality, countries have increased the frequency
of inspections (for example, in most EU15 economies and Bangladesh), created a
national-level firm or employee registry (Poland), and launched public awareness
campaigns regarding tax compliance (for example, China, Republic of Korea).
21
Such
measures have been most effective in reducing informality when implemented in
conjunction with steps to improve labor market functioning and when applied even-
handedly to both formal and informal firms (Loayza 2018). In Georgia, during 1996-
2016, the transition to a market economy brought significant improvements in
government effectiveness, control of corruption, and law and order (World Bank
2019b).
22
With output growth averaging about 6 percent per year, the share of informal
output fell by 9 percentage points of GDP, and the share of informal employment in
total employment fell by a similar magnitude.
21
See, for instance, Awasthi and Engelschalk (2018); Bruhn and McKenzie (2014); De Giorgi, Ploenzke, and
Rahman (2018); and Oviedo, Thomas, and Karakurum-Özdemir (2009). The EU15 were the members of the
Euroean union before 2004.
22
From 1996 to 2016, Georgia’s global ranking on regulatory quality improved from 150th to 34th place, and
its ranking on government effectiveness improved from 123th to 55th place.

Lower informality after governance reforms. Stricter enforcement of government
regulations and a better legal framework can increase the costs of remaining in the
informal economy (Dabla-Norris, Gradstein, and Inchauste 2008). Anti-corruption
efforts and stronger law and order may allow fewer opportunities for informal firms to
avoid the obligations of formal firms (Choi and Thum 2005; Dreher and Schneider
2010; Iriyama, Kishore, and Talukdar 2016). Better control of corruption can also
reduce informality via the tax morale channel (DeBacker, Heim, and Tran 2015;
Luttmer and Singhal 2014). Empirically, a 1-standard-deviation improvement in the

control of corruption was associated with a cumulative decrease in output informality by
about 0.1 percentage point of GDP in the following three to five years.
Education and training programs
Poorer education associated with greater informality. Informal workers tend to be less
skilled, and therefore also less productive, than formal-economy workers (chapter 4;
Loayza 2018; Perry et al. 2007). In fact, wage differentials between formal and informal
workers have primarily reflected differences in educational backgrounds and experience
(box 4.1). Workers in EMDEs with above-median output informality have, on average,
one year less of schooling than those in other EMDEs (figure 6.11). Poorer access to
schooling and qualified teachers has resulted in significantly poorer education outcomes,
measured by PISA test scores, in EMDEs with above-median output informality.
Entrepreneurship training, at all levels of education, including education programs
aimed at equipping entrepreneurs to create and manage SMEs, is significantly less
accessible in EMDEs with above-median output informality.
Over time, improved education and training. Since 1990, education outcomes and skill
levels have improved: thus, on average in EMDEs, average years of schooling have
increased by about two years (figure 6.11). Entrepreneurship training has also become
more accessible in EMDEs, and the improvement has been statistically significantly
more pronounced in EMDEs with above-median informality. In some EMDEs, training
programs have boosted worker income and firm revenue in the informal sectors (Burki
and Abbas 1991; Verner and Verner 2005). These training programs were also
supported by general improvements in access to primary education and literacy rates
(Aziz et al. 2014; Hathaway 2005).
Lower informality after improvements to training and education. To the extent that
workers remain in the informal sector for lack of human capital or skills, better and
more accessible public education may help workers (or their dependents) move into
better paid formal employment (Andrews, Sánchez, and Johansson 2011; Maloney
2004; Perry et al. 2007).
Empirically, additional entrepreneurship training and improved education outcomes
have been accompanied by significant declines in output informality.
Five years after a 2-
standard-deviation increase in access to entrepreneurship training and education at
primary and secondary levels, output informality was statistically significantly lower, by
0.2 percentage point of GDP.
23
A 10-point increase in the PISA reading score was
associated with a significant decline in output informality, by about 0.1 percentage
point of GDP, over the following two years.
23
Such an improvement was accompanied by a significant reduction in employment informality, by 1.3
percentage points of employment, over three to four years.

Access to finance
Less access to finance in more informal economies. Firms in the informal sector have
less access to credit from the banking sector and capital markets, which restricts their
ability to invest, including in productivity-enhancing technologies (Capasso and Jappelli
2013; D’Erasmo 2016; Ferreira-Tiryaki 2008; box 6.1; figure 6.12). In EMDEs with
above-median informality, about one-third of firms identified access to finance as a
major constraint—8 percentage points higher than in EMDEs with below-median
informality. Households in EMDEs with below-median informality have access to
significantly more commercial bank branches, ATMs, and credit than those in other
EMDEs. About half of the population in EMDEs with below-median informality owns
an account at a financial institution or used a mobile money service recently—about 17
percentage points higher than in EMDEs with below-median informality.
Over time, expanded access to finance. EMDEs, especially in EAP, Middle East and
North Africa (MNA), South Asia (SAR), and, more recently, SSA, have implemented a
series of reforms to improve access to finance. Such reforms mainly aim to strengthen
credit reporting systems and improve the effectiveness of collateral and bankruptcy laws
(World Bank 2020a). Overall, financial development improved in about 90 out of 142
of EMDEs over the period 2010-18 (figure 6.12). The number of ATMs per 100,000
adults rose by 50 percent between 2010 and 2018, and the share of population with an
account at a financial institution increased from 33 percent to 51 percent. Domestic
credit to the private sector increased by about 4 percentage points of GDP over the same
period. Access to credit has been facilitated for firms in the informal sector by
introducing credit information bureaus and better use of information and
communication technology (Capasso, Monferrà, and Sampagnaro 2018). Personal
property registration has also made loans more accessible for firms operating in the
informal economy (for example, in the Czech Republic; World Bank 2012). Digital
payment systems have provided an entry point into the formal financial system and
encouraged a shift away from informal finance (for example, in Kenya; World Bank
2017).
Lower informality after expanded access to finance. Lower financing costs and easier
access to credit can entice informal firms with promising investment projects that
require external finance to enter the formal economy (box 6.1). Empirically, adding 10
more bank branches per 100,000 adults was followed by a decline of 0.1 to 0.3
percentage point in the share of informal output in the following one to five years. A 10-
percentage-point-of-GDP increase in domestic credit to the private sector was associated
with a significant contraction in output informality, by 0.1 percentage point of GDP
over the subsequent one to five years.
Conclusion
The COVID-19 (coronavirus) pandemic plunged the global economy into an
unprecedented contraction in 2020, and it is likely to leave lasting scars on long-term

potential output (World Bank 2020b, 2021). Informal sector workers have been among
the hardest hit because they are disproportionately employed in the services sector that
has been particularly disrupted by the pandemic, work in crowded conditions where the
virus can spread easily, and have limited access to savings or government support
programs (box 2.1). The limited access to sanitation facilities and medical resources in
EMDEs with more pervasive informality illustrates further the development challenges
posed by informality. The pandemic has served as a reminder of the long-standing need
for policies to address the challenges associated with, and caused by, informality. To
achieve the Sustainable Development Goals, policy makers need to boost productivity
growth in both formal and informal sectors and reduce the vulnerabilities of firms and
workers in the informal economy.
Policies are more likely to succeed in addressing the challenges of informality if they are
comprehensive and tailored to country circumstances. Past failures of reforms to lower
informality and boost productivity have in part been attributed to reform design that
was not tailored to country specifics and not sufficiently embedded in a supportive
institutional and business environment, in addition to not being consistently
implemented (Birdsall, de La Torre, and Caicedo 2010; Loayza 2018).
A comprehensive strategy: The right policy mix. Individual policy interventions in
isolation may have only a limited impact on informality, and have unwelcome
unintended consequences (annex 6A; Oviedo, Thomas, and Karakurum-Özdemir 2009;
Ulyssea 2018). A coherent reform strategy is needed, with reforms that complement
each other and address the complexity of informality (Loayza 2018). Success also
depends on careful monitoring of potential unintended consequences and on a
supportive macroeconomic, political, and institutional environment. The latter should
ensure the political and fiscal viability of reform implementation and reduce the
transition costs for workers moving from the informal sector to the formal sector.
A tailored strategy: Addressing economy-specific priorities. Because the causes and
features of informality differ considerably across countries, policy makers need to
identify economy-specific reform priorities. In countries where informality is
predominantly associated with poor governance, a policy package could streamline
regulatory and tax frameworks while improving the efficiency of public revenue
collection and regulatory enforcement as well as strengthening public service delivery to
bolster tax morale. In countries where informality is predominantly a reflection of
underdevelopment, a policy package could include expanded access to finance, markets,
and inputs to foster firm productivity and growth; better education to facilitate formal
sector employment; and enhanced safety nets to cushion household risks. In SSA, SAR,
and MNA economies that are not members of the Gulf Cooperation Council, for
example, general education and training programs to raise human capital could be
prioritized (World Bank 2019b; chapter 5). In LAC, reducing high tax and regulatory
costs faced by businesses could incentivize firms to join the formal sector. In ECA,
improving government effectiveness and reducing corruption could be policy priorities.
292 C H A P T E R 6 T
H E L O N G S H A D O W O F I N F O R M A L I T Y
New policy challenges. The emerging “gig” economy poses opportunities and policy
challenges with its higher accessibility, more fluid labor arrangements, and greater
reliance on digital technology than more traditional forms of informality. Because gig”
workers do not fully participate in the social security system, they are, by some
definitions, informal workers (Loayza, Servén, and Sugawara 2010). Regulatory changes,
especially in the context of social security systems, can help ensure that “gig” workers’
economic risks are manageable and that they do not permanently lose access to the
formal economy (World Bank 2014, 2016, 2018c). These workers may take on many
different assignments over the course of their careers, making the ability to learn and
adapt essential. Policies can support this adaptability with more provision of education
and (re)training programs (Card, Kluve, and Weber 2018; World Bank 2019a).
Increased emphasis on the development of cognitive skills in primary and secondary
education can also help (Almeida, Behrman, and Robalino 2012; World Bank 2018a,
2018c).
New policy opportunities. New technologies offer governments opportunities both to
reduce the incentives for and increase the cost of operating informally while also
providing boosts to productivity that can propel firms into the formal economy. New
technologies can help strengthen tax administration and improve access to finance,
including by making it easier to broaden the tax net and assess credit worthiness.
24
Digitalization can lower regulatory burdens. For example, Costa Rica reduced the time
required to register a business by digitizing tax registration records and company books
in 2009 (World Bank 2009). This was followed by a drop in informal employment by 4
percentage points of total employment and a fall in informal output by about 2
percentage points of official GDP during 2009-16 (World Bank 2019b). Similar reforms
have been carried out in Guyana (2010) and Kenya (2011; World Bank 2010, 2011).
Safeguarding informal workers during severe shocks. COVID-19 has taken an
especially heavy humanitarian and economic toll on EMDEs with large informal sectors
(World Bank 2020b). The vulnerabilities of the informal sector, associated with low
incomes and limited access to government benefits and public services, have amplified
the economic shock from COVID-19 and the related threat to livelihoods (OECD
2020). In many countries, the pandemic has revealed severe shortcomings in social
security systems and governments’ ability to support vulnerable groups (Busso et al.
2020; Loayza and Pennings 2020).
25
Despite their high costs, untargeted programs may
be warranted during such a crisis to maximize the reach to informal-economy
participants; their long-term fiscal burden can be minimized by prioritizing temporary
and reversable measures. To prevent hysteresis in formal-sector job losses, policies can
aim to preserve formal-sector employment opportunities while protecting the poor and
informal workers through food aid and cash transfers (Alfaro, Becerra, and Eslava 2020).

ANNEX 6A Policies and informality
The link between policies and informality is analyzed via the local projection model. It
focuses on showing the cumulative change in informality following policy changes.
Definitions
Both output informality and employment are considered in the regression analyses here.
Output informality is proxied by estimates based on the dynamic general equilibrium
(DGE) model in percent of official GDP, and employment informality is proxied by
self-employment in percent of total employment. Both measures cover up to 125
EMDEs over the period 1990-2018. For the estimation of the local projection model,
all data series are detrended using the Hodrick-Prescott (HP) filter.
Policy indicators
The following policy measures were considered, covering up to 121 EMDEs for 1990-
2018 (table 6B.2).
26
Tax rates. Corporate, individual, and VAT rates from Végh and Vuletin (2015; updated
to 2019) using data from the Organisation for Economic Co-operation and
Development, University of Michigan, and KPMG.

Although the data for some indicators are available for more than 121 EMDEs, the regressions cover up to
121 EMDEs.
Future research.
Some policy areas remain underexplored in the literature. First,
digitalization is a recent development in EMDEs that holds great potential for informal-
economy participants and policy makers. Yet little is known about the impact of
digitalization of government services or private economic activity on the informal
economy, including relative to the formal economy. The possibility that digitalization
will disproportionately benefit formal firms, and thus shrink the relative size of the
informal sector, deserves examination. Second, past studies have focused on the impact
of policies on formalization without looking into their effects on the resilience of the
informal economy. Future studies could examine policies that can improve the resilience
of the informal economy and prevent informal participants from being tipped into
poverty by negative shocks such as COVID-19. Last, the chapter has not touched upon
some emerging ideas regarding how governments can better engage with informal
businesses, such as providing a simplified, intermediate, and temporary legal status to
informal businesses that could be aligned with both business needs and government
goals (Marusic et al. 2020).

100,000 adults, a common measure for the access to financial institutions, is obtained
from Global Financial Development Database (World Bank 2019c);
Labor market regulation. Labor market efficiency index from World Economic Forum’s
Global Competitiveness Report (ranging from 1 to 7 with a higher score indicating a
more efficient labor market) and the index for hiring and firing regulation from Fraser
Institute (Fraser Institute 2020; 1 = firing and hiring are most determined by regulations
but not by the employer, and 10 = firing and hiring are mostly determined by the
employer but not by regulations).
Governance. Bureaucracy quality, control of corruption, and law and order are from the
International Country Risk Guide (ICRG; 1 = worst governance, and 4/6 = best
governance).
Government services. Survey responses on the presence and quality of programs directly
assisting SMEs at all levels of government (national, regional, municipal; “government
programs”) and on the presence of property rights, commercial, accounting, and other
legal and assessment services and institutions that support or promote SMEs
(“commercial and professional infrastructure”), taken from the National Expert Surveys
of the Global Entrepreneurship Monitor for the period 2000-19 (ranging from 1 to 4
with a lower score representing poorer entrepreneurial conditions). Survey responses on
the extent to which training in creating or managing SMEs is incorporated within the
education and training system at primary and secondary levels (“basic school”) are also
taken from the National Expert Surveys of the Global Entrepreneurship Monitor.
Mobile phone subscriptions per 100 people are taken from World Development
Indicators.
Firm start-up costs. Cost of business start-up procedures in percent of GNI per capita
and time required to start a business in days are from Doing Business (World Bank
2020a).
Education and health outcomes. Life expectancy at birth and PISA test scores for
reading (students aged 15) are from WDI (World Bank 2020c).
Model specification: The local projection model
A local projection model as in Jordà (2005), Teulings and Zubanov (2014), and World
Bank (2018c) is used to identify the effects of policy changes on informality over time.
In impulse responses, the model estimates the effect of policy changes on cumulative
changes in the cyclical component of (DGE-based) informal output in percent of official

The results are robust to using levels of DGE-based informal output (figure 6A.1).
28
In the case of corporate and individual tax rates, the levels of both tax rates at year t in country i are also
included as control variables. The results do not change when these two control variables are dropped. Similarly,
when labor tax and contributions is the variable of interest, the level of labor tax and contributions at year t in
country i is included as one of the control variables.

Similar to the results on ratios of informality, improved access and depth of financial institutions are
linked with significant contractions in levels of informal output in the following years.

Source: World Bank.
Note: Data for the period 1990-2018 and EMDEs. Here informal output level is measured by DGE-based estimates on informal output
(in constant 2011 U.S. Dollars). The results are obtained via a local projection method where informality measures are detrended using
Hodrick-Prescott filter. See annex 6A for detailed model specifications. DGE = dynamic general equilibrium model; EMDEs = emerging
market and developing economies.
A-B. Bars show the cumulative changes in DGE-based output informality in percent of GDP following a 10-unit increase in the
number of bank branches per 100,000 people (A) and 10-percentage-point-of-GDP increase in the share of domestic credit to the
private sector in percent of GDP (B). Whiskers show the upper and lower bounds of the corresponding 90 percent confidence
intervals. “t = n” indicates the cumulative changes in output informality over the n years after a policy change.
