We exploit a policy discontinuity at U.S. state borders to identify the effects of unemployment insurance policies on unemployment. Our estimates imply that most of the persistent increase in unemployment during the Great Recession can be accounted for by the unprecedented extensions of...

We develop a method to jointly measure the response of worker search effort (individual effect) and vacancy creation (market-level effect) to changes in the duration of unemployment insurance (UI) benefits. To implement this approach, we exploit an unexpected cut in UI durations in Missouri and...

This paper investigates how a mandatory activation program in Denmark affects the job finding rate of unemployed workers.The activation program was introduced in an experimental setting where about half of the workers who became unemployed in the period from November 2005 to March 2006 were...

A significant fraction of the labor force consists of employed workers who are part-time unemployed (underemployed) in the sense that they are unable to work as much as they prefer. This paper develops a search and matching model to study the design of optimal unemployment insurance in an...

This paper studies optimal unemployment bene…fit levels and optimal proportional income tax rates over the business cycle. Previous research suggests that policy makers should make unemployment insurance (UI) dependent on the business cycle because the UI system can be used to smooth...

This paper analyzes the design of optimal unemployment insurance in a search equilibrium framework where search effort among the unemployed is not perfectly observable.We examine to what extent the optimal policy involves monitoring of search effort and benefit sanctions if observed search is...
