Though falling turnout in recent decades has been recognised as a problem for democracy, the solutions that have been proposed have mostly been drawn from the realms of the marketplace and society, rather than that of democracy. The inadequate empirical theory that subtends many policy initiatives designed to improve turnout accounts for why these initiatives have largely failed to achieve their stated aims. I argue that electoral participation should be seen through the conceptual lens of collective action, and that this (...) approach suggests mandatory electoral participation as an equitable and effective coordination device. I further argue that compulsory turnout offers a good fit with democratic norms of equality, rights and political obligation. (shrink)
