We prove existence, monotonicity and differentiability of firm profits and provide first-order conditions that characterize the properties of the optimal contract. We demonstrate how the shape of the contract depends on the persistence and variance of the productivity process, on worker and firm...

A key question in labor market research is how the unemployment insurance system affects unemployment rates and labor market dynamics. We revisit this old question studying the German Hartz reforms. On average, lower separation rates explain 76% of declining unemployment after the reform, a fact...

Large and persistent earnings losses following displacement have adverse consequences for the individual worker and the macroeconomy. Leading models cannot explain their size and disagree on their sources. Two mean-reverting forces make earnings losses transitory in these models: search as an...

We provide new estimates on worker flow rates in and out of unemployment for Germany covering the last six decades. In the 1980s, Germany emerged as the sick man of Europe with a labor market characterized by persistently high unemployment rates. We attribute a substantial fraction of the rise...

Comparing labor markets in the United States and Germany as Europe's largest economy over the period from 1980-2004 uncovers three stylized differences: (1) Germany's mean transition rates from unemployment to employment (UE) were lower by a factor of 5 and transition rates from employment to...

An extensive empirical literature has documented that workers with high tenure suffer large and persistent earnings losses when they get displaced. We study the reasons behind these losses in a tractable search model with a life-cycle dimension, endogenous job mobility, worker - and match...
