Compulsory Voting and Parties’ Vote‐Seeking Strategies

I advance a theory about how compulsory voting affects the behavior of political parties. The theory suggests that parties will pivot toward programmatic vote‐seeking strategies and away from clientelistic tactics, such as vote buying, where voting is compulsory. I test my expectations in three separate studies, using several data sources and empirical approaches. In Study 1, cross‐national analyses show that parties behave more programmatically under compulsory voting and that vote buying is less common where voting is mandatory. In Study 2, synthetic control and difference‐in‐differences analyses show that a switch to compulsory voting in Thailand produced an increase in programmatic vote seeking. In Study 3, a list experiment conducted in tandem with a natural experiment shows that compulsory voting leads parties to rely less on vote‐buying tactics in Argentina. I conclude by discussing the implications of these findings, which together are broadly supportive of my theoretical expectations.
