Abstract

This research note investigates how the voting behavior of middle-income citizens explains why right-wing parties tend to govern under majoritarian electoral rule. The growing literature that investigates the ideological effects of electoral systems has mostly focused on institutional explanations. However, whether the electoral rules overrepresent parties with some specific ideologies is also a matter of behavior. Building on Iversen and Soskice (2006), we test two arguments. First, middle-income groups are more likely to vote for the right under majoritarian rules because they fear the redistributive consequences of a victory of the left in these contexts. Second, middle-income earners particularly concerned with tax rates are particularly prone to vote differently across electoral systems. Combining survey evidence from the Comparative Study of Electoral Systems and the New Zealand Election Study, we show that the voting behavior of middle-income citizens is indeed responsible for the predominance of the right under majoritarian systems.
