1 Corruption in Developing Countries Benjamin A. Olken, MIT Rohini Pande, Harvard University February 2012 ABSTRACT Recent years have seen a remarkable expansion in economists’ ability to measure corruption. This, in turn, has led to a new generation of well-identified, microeconomic studies. We review the evidence on corruption in developing countries in light of these recent advances, focusing on three questions: how much corruption is there, what are the efficiency consequences of corruption, and what determines the level of corruption. We find robust evidence that corruption responds to standard economic incentive theory, but also that effects of anti-corruption policies often attenuate as officials find alternate strategies to pursue rents. * This paper was originally written as part of the Abdul Latif Jameel Poverty Action Lab’s Governance Initiative, which is funded by DFID, the Hewlett Foundation, and an anonymous donor.
