We re-examine the optimality of tax smoothing from the point of view of frictional labor markets. Our central result is that whether or not this cornerstone optimal fiscal policy prescription carries over to an environment with labor market frictions depends crucially on the cyclical nature of...

Heterogeneity between unemployed and employed individuals matters for optimal fiscal policy. This paper considers the consequences of welfare heterogeneity between these two groups for the determination of optimal capital and labor income taxes in a model with matching frictions in the labor...

I examine whether the cyclical behavior of unemployment has changed over the post WWII period. Specifically, I test whether cyclical movements in unemployment have become more persistent. Finding that they have, indeed, become more persistent, I then take some initial steps in explaining why. I...

Shimer (2005) argues that the Mortensen-Pissarides (MP) model of unemployment lacks an amplification mechanism because it generates less than 10 percent of the observed business cycle fluctuations in unemployment given labor productivity shocks of plausible magnitude. This paper argues that part...

In predicting the magnitude of the labor supply response to taxation, the standard lifecycle labor supply model distinguishes between unanticipated and anticipated changes in the after-tax return to working. Exploiting age-eligibility rules for claiming a dependent on a tax return facilitates a...

This paper examines the determinants of the natural rate of unemployment using a combined cross section and time series data set. The results suggest that industry composition affects the natural rate. In particular, a higher share of temporary employment in a local labor market tends to lower...

This paper shows that labor markets of emerging economies are characterized by large fluctuations in wages while employment fluctuations are subdued. We find that a real business cycle model of a small open economy that embeds a Mortensen-Pissarides type of search-matching frictions can account...
