One goal of extending the duration of unemployment insurance (UI) in recessions is to increase UI coverage in the face of longer unemployment spells. Although it is a common concern that such extensions may themselves raise nonemployment durations, it is not known how recessions would affect the magnitude of this moral hazard. To obtain causal estimates of the differential effects of UI in booms and recessions, this paper exploits the fact that, in Germany, potential UI benefit duration is a function of exact age which is itself invariant over the business cycle. We implement a regression discontinuity design separately for twenty years and correlate our estimates with measures of the business cycle. We find that the nonemployment effects of a month of additional UI benefits are, at best, ...

The majority of papers analyzing the employment effects of unemployment insurance (UI) benefit durations focuses on the duration of the first unemployment spell. In this paper, we make two contributions. First, we use a regression discontinuity design to analyze the long-term effects of extensions in UI durations. These estimates differ from standard estimates that they incorporate differences in UI benefit receipt and employment due to recurrent unemployment spells. Second, we derive a welfare formula of UI extensions that incorporates recurrent nonemployment spells. We find that accounting for nonemployment beyond the initial spell leads to a significant reduction in estimates of the nonemployment effect of UI extensions by about 25 percent. We show this effect is only partly explained b...
