How Electoral Systems Can Influence Policy Innovation

Abstract

This paper argues that in certain areas of policy, electoral systems can influence policy innovation (how early countries will adopt certain policies). Electoral systems influence the number of parties that win representation and thereby influence the diversity of perspectives included in the policymaking process. It is argued here that this diversity facilitates elite and public consideration of new issues and ideas, and consequently, it leads to earlier debate and action on these issues and ideas. This dynamic is particularly relevant to controversial issues and ideas that major parties may be hesitant to address and that minor parties may be more incentivized to promote. In this paper, two issues/ideas are considered: extending rights to same-sex couples and making material sacrifices to protect the environment. I show that countries with more proportional electoral systems tend to act earlier to protect the environment and that they tend to be early adopters of civil union legislation. These results are also supported by World Values Survey data showing public preference patterns that support these policy outcomes.
