Standard models suggest that adverse labor demand shocks will lead to bigger employment losses if institutional factors like minimum wages and trade unions prevent downward wage adjustments. Some economists have argued that this insight explains the contrast between the United States, where real...

We adopt a general equilibrium approach in order to measure the effects of recent immigration on the Western German labor market, looking at both wage and employment effects. Using the Regional File of the IAB Employment Subsample for the period 1987-2001, we find that the substantial...

Shimer (2005) pointed out that although we have a satisfactory theory of why some workers are unemployed at any given time, we don?t know why the number of unemployed workers varies so much over time. The basic Mortensen-Pissarides (1994) model does not generate nearly enough volatility in...

Concave hiring rules imply that firms respond more to bad shocks than to good shocks. They provide a unified explanation for several seemingly unrelated facts about employment growth in macro and micro data. In particular, they generate countercyclical movement in both aggregate conditional...

In this paper, we estimate the relationship between cyclical changes in aggregate labor market opportunities and child health outcomes. In addition to using state unemployment rates to proxy for labor market conditions, as is common in the existing literature, we construct predicted employment...

This paper studies how producers' idiosyncratic risks affect an industry's aggregate dynamics in an environment where certainty equivalence fails. In the model, producers can place workers in two types of jobs, organized and temporary. Workers are less productive in temporary jobs, but creating...
