Registration Deadlines and Turnout in Context

This paper analyzes the effect of registration deadlines on voter turnout. The theoretical explanation considers how registration deadlines affect turnout when individuals influence the participation of others. The theoretical model leads to a novel empirical hypothesis, that deadlines can have both a direct and indirect effect on turnout through a behavioral contagion process. The paper reports empirical findings that confirm the theoretical expectations. These results have important implications for future research on registration deadlines and Election Day registration as the effects of these reforms depend on the specific social context in which they are adopted.
