This paper examines causes of the persistence of corruption among elected politicians in democracies. We study a theoretical model of competition between two candidates who differ both in ability and popularity in a probabilistic voting setup. Each candidate proposes a tax rate and a public good...

This paper examines causes of the persistence of corruption among elected politicians and the effectiveness of some commonly discussed anti-corruption reforms. We study a theoretical model of competition between two candidates who differ both in ability and popularity in a probabilistic voting...

Using a theoretical model of repeated political competition among two career politicians, I study the incentives of both the corrupt and clean politicians not to adopt a fully effective reform targeting political corruption. In the setup I study, each politician can credibly adopt the reform as...

We compare the legislature quality under an exclusive, centralized selectorate (such as a party-principal) with that under an inclusive, decentralized selectorate (such as a party-primary). In our model, two parties compete over three districts: two are home districts of each party while the...

Prior studies of strategic voting in multi-party elections potentially overestimate the extent of it by counting erroneously votes cast under different motivations as strategic votes. We propose a method that corrects some of this overestimation by distinguishing between strategic voting (voting...

The noise-trading or coordination channel hypothesis implies that sterilized intervention in the foreign exchange market is effective if certain conditions are satisfied, but ineffective otherwise. The hypothesis is tested with a three-regime threshold model and daily data on actual intervention...

It is widely believed that the countries of Africa trade relatively little with the outside world, and among themselves, despite an extensive network of regional trade agreements. We examine this proposition by focusing on agricultural trade. Specifically, we ask whether non-tariff barriers...
