A Duopoly Model of Political Agency with Applications to Anti-Corruption Reform

Abstract

Using a theoretical model of political competition between two candidates who could differ in their (unverifiable) ability to produce public good, popularity, and ethics, I study the effectiveness of three commonly discussed anti-corruption reforms (higher salaries, higher penalties, and constitutional constraints on fiscal policy). In the model, each candidate proposes an income tax rate and a public good level. The difference between the collected taxes and the cost of public good is stolen by the elected politician. The voting decision is probabilistic. I show that under certain conditions each reform could increase the level of corruption or reduce the voter's welfare through other channels.
