A Macroeconomic Approach to Optimal Unemployment Insurance: Applications

This paper explores how the optimal replacement rate of unemployment insurance varies over the business cycle in the United States. It finds that the optimal replacement rate is countercyclical, just like the actual replacement rate.

A Macroeconomic Approach to Optimal Unemployment Insurance: Theory

This paper develops a theory of optimal unemployment insurance in matching models. It derives a sufficient-statistic formula for optimal unemployment insurance, which is useful to determine the optimal cyclicality of unemployment insurance.

Aggregate Demand, Idle Time, and Unemployment

This paper develops a model of unemployment fluctuations. The innovation is to represent the labor and product markets with a matching structure. The model simultaneously features Keynesian unemployment, classical unemployment, and frictional unemployment.

A Theory of Countercyclical Government Multiplier

This paper develops a New Keynesian model in which the government multiplier doubles when the unemployment rate rises from 5% to 8%. The multiplier is so countercyclical because in bad times, on the labor market, job rationing dwarfes matching frictions.

Do Matching Frictions Explain Unemployment? Not in Bad Times

This paper proposes a matching model of the labor market with job rationing: unemployment does not disappear in the absence of matching frictions. In recessions, job rationing drives the rise in unemployment, whereas matching frictions contribute little to unemployment.
