Can one-time informational interventions cause permanent changes in benefit take-up? In the context the Earned Income Tax Credit, we find evidence that reminding individuals of their eligibility has meaningful effects. Reminder notices have the largest effect among taxpayers without kids,...

We present a model of coarse thinking, in which individuals group situations into categories, and transfer the informational content of a given message from situations in a category where it is useful to those where it is not. The model explains how uninformative messages can be persuasive,...
