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...

We estimate the effects of conditioning benefits on program participation among older long-term unemployed workers. We exploit a Swedish reform which reduced UI duration from 90 to 60 weeks for a group of older unemployed workers in a setting where workers who ex-hausted their benefits received...

This paper studies optimal unemployment benefit 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 consumption...

Conventional measures of unemployment do not capture all dimensions of joblessness. A case in point is underemployment among employed workers, also frequently referred to as parttime unemployment. Workers in this category are employed during a survey week but are unable to work as many hours as...

In this paper we develop an equilibrium search and matching model where two-person families as well as singles participate in the labor market. We show that equilibrium entails wage dispersion among equally productive risk-averse workers. Marital status as well as spousal labor market status...

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...

We analyze the effects of various labor market policies on job creation, job destruction, and employment. The framework of Mortensen and Pissarides (2003) is used to model the dynamic interaction between firms and workers and to simulate their responses to alternative policies. The equilibrium...
