Recent empirical literature finds very limited average effects of generous unemployment benefits on match quality. This study examines those effects in a setting where they could be large. We focus on workers with low employability and evaluate the impact of a large increase in potential benefit duration from 7 to 15 months. Our regression discontinuity design does not elicit significant short-term or medium-term effects on either employment duration or wages, whereas we find large positive effects on unemployment and non employment duration.
