Causes of corruption: a survey of cross-country analyses and extended results

We survey and assess the empirical literature on the sources of corruption Thanks to the improved availability of data, we are able to produce an improved cross-country econometric model to test well-established and more recent hypotheses jointly. We do not find that the common law system, or a past as a British colony predicts corruption. Our results support cultural theories on the causes of corruption, and suggest that a medium-long exposure to uninterrupted democracy is associated with lower corruption levels, while political instability tends to raise corruption. Our results also suggest that the diffusion of newspapers helps to lower corruption levels.      

Private and public investment in sub-Saharan Africa: The role of instability risks

This paper explores the impact of public investment on private investment in sub-Saharan Africa using the finite mixture model. We argue that the impact of public investment on private investment differs across groups of countries with similar but unobserved characteristics. Contrary to previous studies, the paper incorporates the potential presence of hidden heterogeneity and tries to explain the group membership. Using a sample of 42 countries, we find that the impact of public investment on private investment differs across three different groups of countries. Moreover, we find that countries with high risk of conflict, terrorism and repatriation of profits are less likely to be in the group where public investment crowds in private investment. The paper underscores the need for sub-Saharan African countries to ensure private investment security by reducing the risks associated with conflicts and terrorism, and preserving contract viability and repatriation of profits.     

Growth and welfare effects of corruption penalties

This paper analyses the steady-state effect of business corruption penalties on economic growth, corruption and welfare. To that end, the baseline horizontal R&D growth model is extended to include corruption, which is generated in intermediate goods production. Taxation on corruption depresses profits in production but also wages, leading to labor being reallocated from production to R&D, and, therefore, to a higher economic growth rate. Moreover, it also reduces corruption and increases welfare if preferences towards a corruption-free environment are strong enough. The results are in line with the data observed for 15 EU countries.     

Economic growth and inequality: The role of public investment

The relationship between growth and inequality is complex. After discussing some general background issues, motivated by extensive empirical evidence this paper focuses on public investment as a key determinant of the relationship. Two alternative frameworks, each offering sharply contrasting perspectives, are presented. The first employs the “representative consumer theory of distribution” where agent heterogeneity originates with wealth endowments. It yields an equilibrium in which aggregate dynamics drives distributional dynamics. In the second, agent heterogeneity arises from idiosyncratic productivity shocks and generates an equilibrium in which distributional dynamics drive growth. The impact of government investment on growth and inequality are shown to contrast sharply in the two approaches, thus illustrating the complexity of the growth-inequality relationship.     

Public investment allocation across Ecuadorian Provinces

We propose a theoretical framework which allows us to obtain a tractable equation for empirical implementation that relates the growth rate of public investment per capita by the central planner to variables typically associated with traditional public investment allocation criteria. Panel data for the Ecuadorian provinces over the period 2008–2015 are used. The results suggest that the central planner managed to deal with the traditional equity-efficiency trade-off, as well as the decongestion of some public services such as public transport and education. Additional evidence was also found that might raise suspicions regarding distributive politics.     

Credit bureaus,corruption and banking stability

This study assesses the impact that credit bureaus can have on the occurrence of banking crises, using data for 32 countries over the period 2004–2016 while considering the interference effect of corruption. Different levels of income are considered in order to check for the stability of the relationship. We also test for the existence of a threshold effect driving the credit bureau-banking stability nexus. Estimation outcomes suggest that more credit bureaus are correlated with less banking instability. Moreover, estimation outcomes show that curbing corruption improves the quality of information on delinquent borrowers shared among these institutions and can thus enhance the soundness of the banking system. Our findings also report the existence of a nonlinear relationship in the private and public credit bureaus and banking stability nexus.     

Bureaucratic corruption and profit tax evasion

Firms may evade taxes on profits and can also avoid fulfilling legal restrictions on production activities by bribing bureaucrats. It is shown that the existence of tax evasion does not affect corruption activities at the firm level, while the budgetary repercussions of tax evasion induce less corruption. Policy measures which alter the gains or losses from corruption have a non-systematic impact on tax evasion behaviour.      

Public infrastructure investment,output dynamics,and balanced budget fiscal rules

We study the dynamic macroeconomic effects of public infrastructure investment under a balanced budget fiscal rule, using an overlapping generations model of a small open economy. The government finances public investment by employing distortionary labor taxes. The balanced budget rule implies a negative short-run output multiplier that exceeds (in absolute terms) the positive long-run output multiplier. Larger public capital spillovers sharpen the intertemporal output tradeoff. In contrast to conventional results regarding public investment shocks, we obtain dampened cyclical responses for plausible parameter values. The cyclical dynamics arise from the interaction between the labor tax rate, the tax base, and the intergenerational spillover effects. We show that financing scenarios involving public debt creation can substantially reduce the short-run output contraction and the transitional macroeconomic fluctuations induced by public investment.     

Press freedom and corruption in business-state interactions

We show that press freedom has a role in constraining business corruption. Using firm-level data, we find that countries with greater press freedom have significantly fewer incidences of bribery involving public officials. In particular, we find that a free press is associated with a substantial reduction in the percentage of firms that report corruption during interactions with tax officials and when obtaining construction permits. Furthermore, we find that fewer businesses in these countries report that corruption is the biggest problem that they face. These findings highlight the role of an independent media in combating corruption.     

Long-run growth and welfare effects of public policies with distortionary taxation

In a one-sector growth model with infrastructure investment, we study the impact of fiscal policies on growth. The government collects taxes on labor income and profits. The government uses these revenues to purchase infrastructure investment, provide utility enhancing government services, and to provide transfer payments to the households. We show that the balanced growth rate is an increasing function of the percent of government revenues that goes to infrastructure. We find that the growth maximizing mix of taxes depends on the elasticity of substitution between inputs. In particular, with distortionary taxes, the growth maximizing tax rate on capital is higher the lower the elasticity of substitution between private physical capital and public capital. In addition, the growth maximizing size of the government is higher when the elasticity of substitution between public and private inputs is low. We also investigate welfare effects of other public expenditures as well. Depending on the elasticity of substitution in production, the welfare implications of different public policies can be substantial.     

Does corruption affect income inequality and poverty?

This paper provides evidence that high and rising corruption increases income inequality and poverty. An increase of one standard deviation in corruption increases the Gini coefficient of income inequality by about 11 points and income growth of the poor by about 5 percentage points per year. These findings are robust to use of different instruments for corruption and other sensitivity analyses. The paper discusses several channels through which corruption may affect income inequality and poverty. An important implication of these findings is that policies that reduce corruption will most likely reduce income inequality and poverty as well.

Preventing rather than punishing: An early warning model of malfeasance in public procurement

Is it possible to predict malfeasance in public procurement? With the proliferation of e-procurement systems in the public sector, anti-corruption agencies and watchdog organizations have access to valuable sources of information with which to identify transactions that are likely to become troublesome and why. In this article, we discuss the promises and challenges of using machine learning models to predict inefficiency and corruption in public procurement. We illustrate this approach with a dataset with more than two million public procurement contracts in Colombia. We trained machine learning models to predict which of them will result in corruption investigations, a breach of contract, or implementation inefficiencies. We then discuss how our models can help practitioners better understand the drivers of corruption and inefficiency in public procurement. Our approach will be useful to governments interested in exploiting large administrative datasets to improve the provision of public goods, and it highlights some of the tradeoffs and challenges that they might face throughout this process.     

The incidence and persistence of corruption in economic development

Economic development and bureaucratic corruption are determined jointly in a dynamic general equilibrium model of growth, bribery and tax evasion. Corruption arises from the incentives of public and private agents to conspire in the concealment of information from the government. These incentives depend on aggregate economic activity which, in turn, depends on the incidence of corruption. The model produces multiple development regimes, transition between which may or may not occur. In accordance with recent empirical evidence, the relationship between corruption and development is predicted to be negative.     

Interregional tax competition and intraregional political competition: The optimal provision of public goods under representative democracy

This paper explores the implications of the interaction between interregional tax competition and intraregional political competition for the optimal provision of public goods under representative democracy à la (Osborne and Slivinski, 1996) and (Besley and Coate, 1997). As an extension of Hoyt’s (1991) finding that intensified tax competition is always harmful and aggravates the extent to which public goods are undersupplied in a region, we show that intensified tax competition can be beneficial if political as well as tax competition is considered. In particular, we identify plausible conditions under which (i) there is an optimal intensity of tax competition such that the interaction between interregional tax competition and intraregional political competition will result in the optimal provision of public goods and (ii) intensified tax competition will be beneficial if and only if the degree of tax competition is less than this optimal intensity.     

Incomplete markets, ambiguity, and irreversible investment

The problem of irreversible investment with idiosyncratic risk is studied by interpreting market incompleteness as a source of ambiguity over the appropriate no-arbitrage discount factor. The maxmin utility over multiple priors framework is used to model and solve the irreversible investment problem. Multiple priors are modeled using the notion of κ‐ignorance. This set-up is used to analyze finitely lived options. For infinitely lived options the notion of constant κ‐ignorance is introduced. For these sets of density generators the corresponding optimal stopping problem is solved for general (in-)finite horizon optimal stopping problems driven by geometric Brownian motion. It is argued that an increase in the set of priors delays investment, whereas an increase in the degree of market completeness can have a non-monotonic effect on investment.     

Issues in New Political Economy: An Overview

A brief overview of the historical background, nature, and rapid growth in volume and scope of new political economy since the early 1980s is provided. the paper continues with some general reflections on the strengths and weaknesses of the new political economy approach, illustrated by the other contributions to this special issue of the Journal of Economic Surveys . The final Section summarises these contributions.     

The wisdom of demagogues: institutions,corruption and support for authoritarian populists

This article analyses the drivers of support for authoritarian populist parties in Europe. Such parties claim to represent the interests of ordinary people against greedy and out‐of‐touch elites. Simultaneously, they reject conventional constraints on democratic policymaking. In recent years, such parties on the political left and right have been gaining influence in countries across Europe. Using a panel data set from 1980–2016, we use semiparametric Tobit models with country fixed effects to explain support for authoritarian populists. We find that large vote shares of right‐wing – but not left‐wing – authoritarian populists are associated closely to corruption. Other commonly cited explanations such as unemployment, inequality and immigration perform poorly in predicting support for populist political platforms on the political right. While a full theoretical explanation of the link between corruption and right‐wing populism remains beyond the scope of this article, we suggest that the mechanism involves political trust. Corruption weakens trust in political institutions, which populists exploit. Curbing the rise of right‐wing authoritarian populism in Europe will thus require restoring trust in the integrity of politics.     

Multi-sectoral interdependencies of regional public infrastructure investments

Public investment decision-making processes involve multiple and interrelated sectoral and regional policy objectives and budget constraints. This paper presents a dynamic spatio-economic model that considers multi-sectoral investment interdependencies using data at the prefecture level in Greece. The expenditure allocation dynamics of most types of regional public investment are found to be competitive with each other. This outcome is attributed to the lack of policy coordination, technological and budget constraints, geographical factors, and equity and political considerations. The investment interrelationships may have a significant effect on future state funding needs and the strategic assessment of infrastructure development at the country level.     

Natural disasters,growth and institutions: A tale of two earthquakes

We examine the impact of natural disasters on GDP per capita by applying the synthetic control approach and using a within-country perspective. Our analysis encompasses two large-scale earthquakes that occurred in two different Italian regions in 1976 and 1980. We show that the short-term effects are negligible in both regions, though they become negative if we simulate the GDP that would have been observed in absence of financial aid. In the long-term, our findings indicate a positive effect in one case and a negative effect in the other, largely reflecting divergent patterns of the TFP. Consistent with these findings, we offer further evidence suggesting that a quake and related financial aid might either increase technical efficiency via a disruptive creation mechanism or reduce it by stimulating corruption, distorting the markets and deteriorating social capital. Finally, we show that the bad outcome is more likely to occur in regions with lower pre-quake institutional quality. As a result, our evidence suggests that unanticipated local shocks are likely to change long run growth rates, exacerbating territorial disparities.     

Globalization,political institutions,financial liberalization,and performance of the insurance industry

This paper investigates the impacts of globalization, political institutions, and financial liberalization on the performance and risk-taking of insurance firms covering 1324 individual firms in 30 selected OECD countries. We find that greater globalization and a stable political institution lead insurance companies to exhibit a better performance—i.e., insurers adjust their strategies while being aware of institutional changes. By contrast, financial liberalization has an inverse impact on insurance company performance. Thus, greater globalization and a stable political environment both drive less risk-taking for insurers. These findings are particularly important to insurance markets’ competitors and national policymakers.
