a n wa r s h a h 7 A lthough statistics on corruption are often questionable, the data suggest that corruption accounts for a significant proportion of economic activity. In Kenya " questionable " public expenditures noted by the controller and auditor general in 1997 amounted to 7.6 percent of GDP. In Latvia a recent World Bank survey found that more than 40 percent of households and enterpris...

This paper applies a novel methodology to measure corruption levels in U.S. states, leading to insights which could be useful to policymakers in their effort to reduce unethical behavior. The level of public corruption is difficult to quantify because much of it goes undetected and because different cultures and jurisdictions have different definitions and different degrees of tolerance for cor...

The author builds an agent-based model wherein the societal corruption level is derived from individual corruption levels optimally chosen by heterogeneous agents with different risk aversion and human capital. The societal corruption level, in turn, affects the risk-return profile of corruption for the individual agents. Simulating a multi-generational economy with heterogeneous agents, the au...

This companion paper suggests the potential benefits of applying Steven Lukes’ dimensions of power model to the study of corruption in health systems. Lukes’ model sets out three “faces of power” classified by their influence on political discourse, resulting in overt, covert and latent discussion of issues depending on the degree of their alignment with the agenda of d...

The determinants of corruption have long been an important subject for research in the fields of economics and political science. The literature has identified a wide range of factors that cause corruption; however, little research has been done on how the design of government policy influences corruption. We advance a new factor, the tax structure being measured as both tax mix and tax complex...

Corruption has been described as a disease. When corruption infiltrates global health, it can be particularly devastating, threatening hard gained improvements in human and economic development, international security, and population health. Yet, the multifaceted and complex nature of global health corruption makes it extremely difficult to tackle, despite its enormous costs, which have been es...

We study corruption as a generalized epidemic process on the graph of social relationships. The main difference to classical epidemic processes is the strong nonlinear dependence of the transmission probability on the local density of corruption and the mean field influence of the overall corruption in the society. Network clustering and the degree-degree correlation play an essential role in c...

This paper examines how government regulation in developing countries affects the form of corruption between business customers and service providers in the telecom sector. We match the World Bank enterprise-level data on bribes with a unique crosscountry telecom regulation dataset collected by Wallsten et al. (2004), finding that (1) strong regulatory substance (the content of regulation) and ...

The purpose of this research paper is to investigate whether there exist alterative methods ofexamining the widespread nature of corruption in Russia. According to Transparency International’s most recently published Corruption Perceptions Index 2012, Russia ranks 133 out of 176 countries and territories, indicating that Russia’s public sector is perceived to be a corrupt as those of the Comoro...

Using Transparency International’s ratings of firm disclosures on anticorruption efforts, we find that disclosures are related to firms’ country and industry exposures to corruption, and to enforcement and monitoring variables. We then examine whether firms’ residual anticorruption disclosures are related to subsequent allegations of corruption and subsequent performance. Firms with abnormally ...
