摘要：This paper evaluates the impact of large changes in the duration of unemployment
insurance (UI) in different economic environments on labor supply, job matches, and search be-
havior. We show that differences in eligibility thresholds by exact age give rise to a valid regression
discontinuity design, which we implement using administrative data on the universe of new unem-
ployment spells and career histories over twenty years from Germany. We find that increases in UI
have small to modest effects on non-employment rates, a result robust over the business cycle and
across demographic groups. Thus, large expansions in UI during recessions do not lead to lasting
increases in unemployment duration, nor can they explain differences in unemployment durations
across countries. We do not find any effect of increased UI duration on average job quality, but
show that the mean potentially confounds differential effects on job search across the distribution
of UI duration. However, it appears that for a majority of UI beneficiaries increases in UI duration
may lead to small declines in wages.
