Tax Evasion,Corruption and Market Entry

We analyze the impact of tax policy on the market entry of firms in the presence of corruption and tax evasion. In a world with corruption, firms must bribe corrupt officials to enter the market. For a given level of bribes, higher tax rates and stricter enforcement of taxation decrease tax evasion but typically reduce market entry. However, when the level of bribes reacts to tax policy, higher taxes and stricter enforcement of taxation can have a double benefit. Up to a certain threshold, for which we develop a simple rule, stricter enforcement increases market entry and reduces tax evasion.     

Can corruption encourage clean technology transfer?

We study the impact of environmental regulation on the transfer of a clean technology where bureaucrats are needed for government intervention. In the absence of corruption, when environmental taxes are low, a technology transfer always takes place and it increases total outputs, but may lead to higher pollution levels. However, when corruption is possible, a firm with a dirty technology may choose to bribe a corruptible bureaucrat who will underreport the actual level of emissions, thereby hindering the transfer of clean technology. We show that a less strict anticorruption policy may lead to more bribing, but encourage technology transfers. Moreover, an environment-oriented government would set a deterrent environmental tax to reduce pollution, while an output-oriented government would set a minimum tax rate to eliminate corruption and induce technology transfers. However, a balanced government would tolerate corruption when the cost of bribing is low and the clean technology is sufficiently efficient.     

Economic Reform and Corruption: Evidence from Panel Data

The notion that economic reform can reduce corruption remains prevalent in the policy agenda of international financial institutions, especially of the World Bank. Economic reforms have, therefore, been carried out throughout various parts of the world to improve the performance of the economies. Using data from 94 low‐ and middle‐income nations for the period 1996–2015, this study employs static and dynamic panel analysis to examine whether economic reform undertaken in accordance with the World Bank's reform programs negatively affects corruption. Our findings suggest that enhancing government effectiveness (i.e. independence of civil service from political pressure, provision of quality public services, effective policy formulation and the government's commitment to such policies) and improving public rights and civil liberties could be some of the most promising policies in terms of fighting corruption. The role of economic development and growth in real per capita income is also found to be significant in some of the specifications. However, the assertion that economic reform can reduce corruption is rejected in all the specifications. We rather find evidence that economic reforms negatively affect the ability of democracy to fight corruption, although on a slim margin. The central theme of the implications of our findings is that in combating corruption, social, institutional and legal means are far more important than economic means. The finding thus is compatible with the World Bank's effort in the later years to introduce governance and democracy as effective tool against corruption.     

PUBLIC INVESTMENT,TAX EVASION,AND THE WELFARE EFFECTS OF A TARIFF REFORM

Contrary to the case considered in literature, the experience of developing countries indicates that the tariff reforms have not been revenue neutral due to the heavy dependence of developing countries on trade taxes and pervasive tax evasion. In contrast to the plausibility of a welfare loss shown by the current literature, when the adverse effect of the loss of tariff revenue on public investment is factored in, the welfare outcome of the tariff reforms of past few decades turns out to be much more pessimistic. The constraints imposed by tariff dependence and tax evasion imply that future tariff reforms in these countries should be undertaken after strengthening their domestic tax system and augmenting the ability of their governments to fight tax evasion. For countries of sub‐Saharan Africa, where such reforms are likely to be concentrated, this would need planning and capacity building over a longer time horizon. (JEL D61, D62, F13, H26)     

Population Aging,Health Care,and Fiscal Policy Reform: The Challenges for Japan

We construct a transition analysis based on a general equilibrium life‐cycle model to investigate the effects of aging, and we evaluate various policy alternatives designed to lessen the negative influence of aging. In particular, we analyze reforms of insurance benefits and tax financing tools that were recently the focus of a great amount of attention and debate in Japan because of the tense financial situation there. We show that although the potential reforms improve the welfare of future generations, the political implementation of such reforms is difficult because of the large welfare costs for the current population. Our analysis suggests that a gradual reform with an intergenerational redistribution will be more politically implementable than an immediate reform.     

反腐败、市场建设与经济增长

在市场不完善的情况下，有一部分腐败活动虽然有损于社会公平和正义，而且造成了社会资源的损耗，但对经济资源的配置也有着一定的作用。本文通过一个经济增长模型讨论了代表社会利益的政府如何规划反腐败路径，并保证经济的增长。分析结果表明。政府是可能在反腐败的同时实现经济增长的。一旦政府开始加大反腐败力度，则社会的腐败程度将持续下降。随着市场的完善，经济资源可以更好地借助于市场机制进行配置，这时社会可以加大打击腐败的力度。如果腐败的路径依赖性更强，政府也将加强对腐败的打击。     

GENDER AND PUBLIC ATTITUDES TOWARD CORRUPTION AND TAX EVASION

The topics of corruption and tax evasion have attracted significant attention in the literature in recent years. We build on that literature by investigating empirically: (1) whether attitudes toward corruption and tax evasion vary systematically with gender and (2) whether gender differences decline as men and women face similar opportunities for illicit behavior. We use data on eight Western European countries from the World Values Survey and the European Values Survey. The results reveal significantly greater aversion to corruption and tax evasion among women. This holds across countries and time, and across numerous empirical specifications.

An Exploration of the Greek Shadow Economy: Can Its Transfer into the Official Economy Provide Economic Relief Amid the Crisis?

We explore the determinants of the Greek shadow economy, its interaction with the official economy, and its relationship with corruption. In doing so, we undertake — for the first time — an interdisciplinary review of economic and political studies on the size and determinants of the shadow economy, tax evasion, undeclared work and, moreover, of their relation with corruption in Greece in order to reveal the extent and complexity of these phenomena. We estimate the size and determinants of the shadow economy via a multiple-indicators-multiple-causes (MIMIC) approach. Our findings indicate that the important determinants are factors related to macroeconomic conditions, such as unemployment and GDP growth, and institutional factors, such as tax morale and the rule of law. We also indicate that the shadow economy and corruption are complementary and that the official and the shadow economy substitute each other over the business cycle. An adoption of policy based on these findings would lead to a successful transfer of part of the shadow economy to the official economy, would boost government revenue, and would eventually lead the Greek economy out of the depression that emerged as a result of the sovereign debt crisis.     

Taxation,corruption, and growth

We build an endogenous growth model to analyze the relationships between taxation, corruption, and economic growth. Entrepreneurs lie at the center of the model and face disincentive effects from taxation but acquire positive benefits from public infrastructure. Political corruption governs the efficiency with which tax revenues are translated into infrastructure. The model predicts an inverted-U relationship between taxation and growth, with corruption reducing the optimal taxation level. We find evidence consistent with these predictions and the entrepreneurial channel using data from the Longitudinal Business Database of the US Census Bureau. The marginal effect of taxation for growth for a state at the 10th or 25th percentile of corruption is significantly positive; on the other hand, the marginal effects of taxation for growth for a state at the 90th percentile of corruption are much lower across the board. We make progress towards causality through Granger-style tests and by considering periphery counties where effective tax policy is largely driven by bordering states. Finally, we calibrate our model and find that the calibrated taxation rate of 37% is fairly close to the model׳s estimated welfare maximizing taxation rate of 42%. Reducing corruption provides the largest potential impact for welfare gain through its impact on the uses of tax revenues.     

Border tax adjustments and tariff‐tax reforms with consumption pollution

We develop a model of a small open economy, where pollution per unit of consumption between domestically produced and imported quantities of the same good differs. We show that the first‐best policy combination calls for consumption taxes on all polluting goods, and border tax adjustment (BTA) measures, that is, tariffs or import subsidies. We identify conditions under which well‐known tariff‐tax reform policies for developing economies, such as a consumer‐price‐neutral piecemeal reform of trade and a consumption tax, and a consumer‐price‐neutral reform of all trade and consumption taxes improve welfare. We also evaluate whether reforms of trade taxes alone are superior to consumer‐price‐neutral reforms of trade and consumption taxes.

Tax Evasion,Corruption and Tax Loopholes

This paper addresses tax loopholes that allow firms to exploit borderline cases between legal tax avoidance and illegal tax evasion. In general, tax loopholes are detrimental to a revenue‐maximizing government. This may change in the presence of corruption in the tax administration. Tax loopholes may serve as a separating mechanism that helps governments maximize revenues and curb corruption, which may explain why developing countries only gradually close loopholes in their tax codes.     

Wages and Other Determinants of Corruption

Raising wages has commonly been viewed as an anticorruption policy by policymakers from both governments and multilateral development organizations. Conventional wisdom and recent theoretical work suggest that low wages encourage corruption. Nevertheless, the empirical studies done on the wage– corruption tradeoff are econometric estimates that find no conclusive support for the effectiveness of increasing wages as an anticorruption measure. The unique contributions of this paper are the application of an expected utility model to explain the emergence of corruption, and the use of comparative static results that are consistent with the empirical evidence and useful for the design of anticorruption policies. The most important result from the expected utility model is that anticorruption policies designed to increase the net income of potentially corrupt agents not only may be ineffective but may actually encourage corruption.     

The Benefits of Environmental Fiscal Reforms in an Integrated Europe

This paper analyses the effects of an environmental fiscal reform where the environmental tax revenue is used to reduce the tax burden on labor in order to increase employment. The study tries to assess the benefits generated by this type of reform in an integrated Europe where different degrees of tax harmonization can be achieved. The differential impact of cooperative fiscal reforms versus noncooperative ones is quantified through the use of a newly developed general equilibrium model. The results suggest that only a high degree of harmonization, in which both revenue and expenditure policies are coordinated, can provide significant environmental and employment benefits.     

Reducing tariff evasion: The role of trade facilitation

Can simplifying customs procedures reduce tariff evasion? We measure tariff evasion as the mis-representation of import values in response to increasing tariffs. In a dataset covering 121 countries and the whole set of HS6 product categories in 2012, 2015, and 2017, we show that simplifying border procedures, that is trade facilitation, reduces tariff evasion. Holding tariff rate constant at its mean, improving a country’s overall trade facilitation performance from the 25th percentile to the median reduces tariff evasion by almost 20%. The moderating effect is especially due to improving the pre-shipment legal certainty of customs procedures. Among the potential mechanisms, improving trade facilitation performance is effective in reducing tariff evasion due to under-reporting of import prices, as well as in countries with weaker control of corruption. The results suggest that countries can gradually implement trade facilitation reforms to cost-effectively minimize tariff evasion.     

Dissertation abstract: “Essays in applied economics on the intervention of a third player in agency relationships”

Agency theory has established that appropriate incentives can reconcile the diverging interests of the principal and the agent. Focusing on three applications, this dissertation evaluates the empirical relevance of these results when a third party interacts with the primary contract. The analyses provided rely on either laboratory or natural experiments. First, corruption is analyzed as a two-contract situation: a delegation contract between a Principal and an Agent and a corruption pact concluded between this Agent and a third player, called Briber. A survey of the recent microeconomic literature on corruption first highlights how corruption behavior results from the properties of those two agreements. We thereafter show that the Agent faces a conflict in reciprocities due to those two conflicting agreements. The resulting delegation effect, supported by observed behavior in our three-player experimental game, could account for the deterrence effect of wages on corruption. Second, health care is governed by contradictory objectives: patients are mainly concerned with the health provided, whereas containing health care costs is the primary goal of health care administrators. We provide further insights into the ability of incentives to balance these two competing objectives. In this matter, our theoretical and econometric analysis evaluates how a new mixed compensation scheme, introduced in Quebec in 1999 as an alternative to fee-for-services, has affected physicians’ practice patterns. Free switching is shown to be an essential feature of the reform, since it implements screening between physicians. Finally, the demand for underground work departs from the traditional Beckerian approach to illegal behavior, due to the dependence of benefits from illegality on competitors’ behavior. We set up a theoretical model in which the demand for underground work from all producers competing on the same output market is analyzed simultaneously. We first show that competition drastically undermines the individual benefits of tax evasion. At equilibrium, each firm nonetheless chooses evasion with a positive probability, strictly lower than one. This Bertrand curse could then account for the “tax evasion puzzle” i.e. the overprediction of evasion in models that ignore market interactions. We thereafter show that allowing firms to denounce competitors’ evasion is not likely to solve this curse—by providing a credible threat against price cuts, it fosters illegal work. Empirical evidence from a laboratory experiment confirms these predictions. Without denunciation, experimental firms often choose evasion whereas evasion benefits are canceled out by competition. When introduced, denunciation is rarely used by firms, but the threat makes evasion profitable. JEL Classification K42, I18, D21, C25, C91     

Are electronic government innovations helpful to deter corruption? Evidence from across the world

Electronic government innovations have been a critical development in public administration in recent years. Many countries have implemented e-government policies to enhance efficiency and transparency and combat corruption. This paper examines the impact of e-government on corruption using longitudinal data for more than 170 countries from 2002 to 2020. The empirical results suggest that e-government serves as a deterrent to corrupt activities. We analyse which e-government domains affect corruption, which types of corruption are more affected by e-government and the circumstances under which e-government is more effective in reducing corruption. The empirical results suggest that online service completion and e-participation are important features of e-government as an anticorruption tool. Evidence suggests that e-participation reduces corrupt legislature activities, public sector theft, executive bribery, and corrupt exchanges. The potential of e-government to deter corruption is higher in countries where corruption is moderate or high and economic development is lower. Higher levels of GDP per capita, foreign direct investment, and political rights are also associated with lower levels of corruption.     

CORRUPTION AND POLITICAL AND ECONOMIC REFORMS: A STRUCTURAL BREAKS APPROACH

In this paper we look at the impact of broad policy reforms on the levels of corruption. We use a structural break approach to identify country-specific time periods in which significant shifts in corruption levels take place. We then correlate these times of change with a set of covariates with specific focus on the impact of democratization, and trade and equity market liberalization. We find robust support for the hypothesis that episodes of reduction in corruption levels tend to be correlated with democratization and equity market liberalization.     

Dynamic Tax Evasion with Habit Formation in Consumption*

We model the optimal intertemporal decision of an agent who chooses tax evasion and consumption, over an infinite lifetime horizon, where consumption is driven by habits. We find the following: (i) tax evaders reduce consumption in the early stages of habit accumulation and increase it over time; (ii) habit formation has a dampening effect on tax evasion; (iii) neglecting tax evasion can lead to habit overestimation; (iv) the effect of the tax rate on tax evasion is ambiguous; (v) heavy fines are more efficient than frequent controls in reducing tax evasion.
