Electoral gender quotas have become the subject of a growing literature in comparative politics, with the potential to affect how scholars study a wide range of electoral and representative processes. Yet, debates have emerged over how to define and categorize these policies, with implications for the ability to compare cases and draw broader conclusions about their impact in countries around the globe. Reviewing these perspectives, this article draws on work on concept formation to propose a pragmatic approach, focused on matching typologies to research questions. It emphasizes the advantages of this solution for promoting cumulative research and concludes with some thoughts for future research on gender quotas and comparative politics.
