We develop a dynamic general equilibrium trade model with comparative advantage, heterogeneous firms, heterogeneous workers and endogenous firm entry to study wage inequality during the adjustment after trade liberalization. We find that trade liberalization increases wage inequality both in the...

We use a dynamic general equilibrium trade model with comparative advantage, heterogeneous firms, heterogeneous workers and endogenous firm entry to analyze economic policy meant to compensate the losers of trade liberalization and reduce the ensuing wage inequality. We consider several...

This paper compares the aggregate effects of sectoral reallocation in the United States and Western Germany using a stochastic volatility model of sectoral employment growth. Reallocative shocks have no effect on the natural rate of unemployment in either country, and there is mild evidence that...

In this paper, I estimate a series of long run reallocative shocks to sectoral employment using a stochastic volatility model of sectoral employment growth for the United States from 1960 through 2011. Reallocative shocks (which primarily measure construction and technology busts) have little...

This paper analyzes the effects of short-time work (i.e., government subsidized working time reductions) on unemployment and output fluctuations. The central question is whether the rule based component (i.e., the existence of the institution short-time work) and the discretionary component...

This paper argues that there is a nonzero inflation-unemployment tradeoff in the long-run due to frictional growth, a phenomenon that encapsulates the interplay of nominal staggering and money growth. The existence of a downward-sloping long-run Phillips curve suggests the development of a...

The endorsement of expansionary fiscal packages has often been based on the idea that large multipliers can contrast rising unemployment. Is that really the case? We explore those issues in a New Keynesian model in which unemployment arises because of matching frictions. We compare fiscal...

This paper introduces productivity dependent firing costs in an endogenous separation New Keynesian model. By strictly respecting the bonding critique, we show that firing costs tend to increase the performance of the model along the labor market dimension but fail along the persistence...

Based on a Cox Proportional Hazard analysis of German unemployment spells, structural change of the production process is identified as a major explanation for long-term unemployment. Other important covariates capture labor market institutions, macroeconomic stress factors, and individual...

Whereas microeconomic studies point to pronounced downward rigidity of nominal wages in the US economy, the standard Phillips curve neglects such a feature. Using a stochastic frontier model we find macroeconomic evidence of a strictly nonnegative error in an otherwise standard Phillips curve in...
