In Austria, some states temporarily introduced compulsory voting in national elections. We inves- tigate border municipalities across two states which differ in compulsory voting legislation using a difference-in-differences approach. The results show that compulsory voting increased voter turnout by 3.5 percentage points but we do not find long-run effects. Once compulsory voting was abolished, voter turnout returned to pre-compulsory voting levels. Microdata evidence suggests that compulsory voting tends to crowd out intrinsic motivation for political participation which may explain why compulsory voting is not found to be habit-forming.
