Analyses of the political representation of different income groups have been plagued by a number of problems. Most importantly, it has proved difficult to measure policy-makers' and citizens' preferences on identical scales and disentangle legislator responsiveness to different income groups from various other factors that may affect congruence between legislators and citizens. In this article, we address these issues by exploiting Swiss direct democratic procedures and combining a variety of data. Our analysis demonstrates that legislators are highly responsive to the more affluent, yet we also find important differences across parties. While members of center and right-wing parties appear largely unresponsive to the preferences of lower-income voters, we show that their left-wing counterparts are relatively more responsive to citizens of modest means. Our results herefore suggest that although representation is strongly skewed in favor of the affluent, poor citizens are not without any voice in parliament.
