Does Corruption Impact the Formal-Informal Sector Income Gap? Evidence from Brazil
(with Amir B Ferreira Neto)


Many countries rely on the informal economy to provide a major portion of existing jobs, despite the fact that these jobs are low paying. These same countries also seem to experience a significant amount of corruption. It is possible that corruption exacerbates the existing formal-informal gap, as corruption tends to increase income inequality. Using a combination of individual and municipal level data from Brazil, we show that this is in fact the case. The formal-informal income gap is larger in municipalities that experience more corruption. This finding holds even after controlling for selection into the informal sector and is robust to the exclusion of taxes and corruption related costs from income. Thus, a possible way to address the formal-informal income gap problem may be to first address the problem of corruption.


Political Influence Over the Federal Prosecution of Public Corruption: Evidence from Individual Case Files
 

In the US, federal prosecutors are appointed by the president, confirmed by the Senate, and have significant discretion over which cases they choose to take to court. Federal prosecutors handling an overwhelming majority of corruption cases invites the possibility of political influence in the monitoring of corruption. Using individual case level data, I examine the effect political influence has on federal corruption cases, with a particular emphasis on states that are an important focus in the next presidential election. I find that federal prosecutors tend to use weaker cases to increase corruption convictions in politically important states. This effect seems more significant in Democratic administrations. In addition, it seems that federal prosecutors are most biased when it comes to corruption crimes labeled as “federal,” likely because it is the image of the federal government that prosecutors are trying to maintain or improve.

Executive Influence over Reported Corruption Convictions: Are Conviction Rates a Biased Measure of State Level Corruption?

Using state level data on corruption convictions from the U.S. Department of Justice’s Public Integrity Section (PIN) and political importance over five consecutive presidential terms from 1993-2012, I find evidence that executive influence is an important determinant of reported federal corruption convictions in each state. Specifically, the evidence suggests that corruption conviction rates are higher in politically important states. However, this effect decreases in magnitude and becomes statistically insignificant when states have a governor of the same political party as the president. Thus, it seems that corruption convictions are influenced in ways that benefit the political party of the executive.

Corruption: The Good, the Bad, and the Uncertain revisions requested at the Review of Development Economics
  

This paper argues that the effect corruption has on economic growth depends on the uncertainty involved. Employing data on a cross-section of counties, this paper uses an interaction between the frequency of bribery payments and the uncertainty regarding the delivery of the service in exchange for these bribes, to show that, overall, corruption has a negative impact on growth, unless the uncertainty is minimal. Furthermore, the negative effect of corruption becomes larger in magnitude with higher levels of uncertainty. At extremely high levels of uncertainty a relatively small increase in corruption, equivalent to moving from Sweden to the United States for example, is associated with economically large decreases in economic growth.
