Campaign spending regulation in a model of redistributive politics

Summary. We consider a model in which parties that differ in perceived valence choose how to allocate electoral promises (money, pork-barrel projects) among voters. The party perceived to be less valent has a greater incentive to “sell out” to a favored minority and completely expropriate a fraction of the electorate. By reducing the difference in perceived valence, campaign-finance regulations may reduce the extent of the expropriation and achieve a more equitable political outcome. We analyze various instruments of campaign-finance regulation from this perspective.Received: 20 Februay 2003, Revised: 25 January 2005, JEL Classification Numbers: D72, H2.Nicolas Sahuguet: Correspondence toWe thank Alessandro Lizzeri, George Mailath, and Andrew Postlewaite for their comments.
