abstract

  • We study the strategic behavior of voters in a spatial model of proportional representation, in which the policy space is multidimensional. Our main finding is that in large electorate, under some assumptions on voters' preferences, voters essentially vote, in any equilibrium, only for the extreme parties. We want to thank Partha Dasgupta, Jean-Fran├žois Mertens, Thomas Palfrey, and Shlomo Weber for precious discussions. We also thank an anonymous referee for insightful comments. This paper was partially written while Francesco was visiting Tor Vergata University, which he thanks for the hospitality and financial support. Both authors thank the Ramon y Cajal Fellowship, and acknowledge research funding from the Spanish MEC, Grant SEJ2006-11665-C02-0.
