The Impact of Procedural Information Costs on Voting: Evidence from a Natural Experiment in Chile

This paper uses a natural experiment to identify the effect of a procedural information cost on the electoral registration of young first-time voters. We exploit the fact that information about when the minimum age eligibility requirement is due, either at registration or election-day, is only meaningful for those turning 18 after registration closing day. Using a national dataset on Chilean registration over four elections, we provide evidence of a sharp discontinuity in the registration rate of those youngsters turning 18 at closing date. The effect is both sizable and robust, persists over time, and is similar across income groups.
