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...

I study political competition between two candidates who could differ in their ability, popularity, and ethics. In elections, each candidate proposes a flat (income) tax rate and a public good level. A high(er)-ability candidate can produce the public good using less funds. Collected taxes that...

Using a theoretical model of two-candidate competition, I study the political support for a fully effective and costless reform targeting high level political corruption. I find that when the candidates have a high discount factor, and when the level of political corruption is not too low, both...

Using a theoretical model of two-candidate political competition under probabilistic voting, I study the effectiveness of the following anti-corruption reforms: (i) higher wages for politicians, (ii) higher penalties for political corruption, and (iii) constitutional constraints on the tax rates...

We study the Nash Equilibrium of three-candidate unidimensional spatial competition when candidates differ in their non-policy characteristics (valence). If the voters' policy preferences are represented by a strictly convex loss function, and if the voter density is unimodal and symmetric, then...

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 study the effects of stochastic (probabilistic) voting on equilibrium locations, equilibrium vote shares and comparative statics in a setup with three heterogenous candidates and a single-dimensional issue space. Comparing the equilibria with and without stochastic voting, we find that under...

I study both local and global Nash equilibria of a model of three-candidate unidimensional spatial competition. In the model, candidates may have different non-policy characteristics (valence). Generalizing the base model studied in Evrenk (2009a;b) the model allows for an asymmetric voter density as...
