Manoel Gehrke conducts research on comparative politics and political economy of development, with a regional focus on Latin America and substantive focus on political corruption, accountability, the role of money in politics, and government responsiveness.

Book Project


Manoel Gehrke’s book project examines how reactions by political elites moderate the efficacy of anti-corruption policies. He analyzes the consequences of initiatives such as independent audits of municipal governments, and removals of mayors from office because of corruption in the context of Brazilian municipalities. He demonstrates how the strategies adopted by political elites to remain in power after corruption is revealed affect the efficacy of anti-corruption policies. He uses evidence from a natural experiment and from quasi-experimental methods in addition to extensive archival research (detailed data on corruption cases from judicial records and politicians’ assets).

Political Survival and Politicians’ Enrichment After Anti-Corruption Audits


Do Biometric Identification Machines Help to Clean Up Elections? Evidence from Colombia.

Biometric identification machines (BIMs) are part of a new set of tools available to prevent electoral fraud. These machines allow electoral authorities to tackle the impersonation of voters and the illegal substitution of poll workers, and are currently used in approximately 40 countries. This paper investigates the electoral consequences of BIMs and whether political parties use other kinds of electoral fraud to compensate for the potential effects of the new controls. Taking advantage of their partial deployment in elections to department assemblies in Colombia, I find that the presence of BIMs, on average, increased the vote shares of incumbent legislators in municipalities that are governed by mayors in same political party. Strong local parties strategically evade BIMs and use aggregation fraud to compensate for potential losses in their strongholds. Meanwhile, voters’ experiences with vote buying and intimidation were unchanged. By highlighting unintended consequences of anti-fraud interventions, my findings corroborate the importance of comprehensive strategies to ensure electoral integrity to avoid that well-connected politicians are able to circumvent controls.
