Die Hartz-IV-Reform ist politisch stark umstritten. Mit ihr werden Gefährdungen des Lebensstandards bis hin zu Armut verbunden. Gleichzeitig konnte die Bundesrepublik ihre Arbeitslosenquote über die letzten Jahre so stark senken wie fast kein anderes Land in Europa bzw. der OECD. Welche Rolle...

Many labor market models use both idiosyncratic productivity and a vacancy free entry condition. This paper shows that these two features combined generate an equilibrium comovement between matches on the one hand and unemployment and vacancies on the other hand, which is observationally...

This paper addresses the question of why prolonged regional unemployment differentials tend to persist even after their proximate causes have been reversed (e.g., after wages in the high-unemployment regions have fallen relative to those in the low-unemployment regions). We suggest that the...

This paper analyzes the effects of different labor market institutions on inflation and output volatility. The eurozone offers an unprecedented experiment for this exercise: since 1999, no national monetary policies have been implemented that could account for volatility differences across...

This paper presents a theory explaining the labor market matching process through microeconomic incentives. There are heterogeneous variations in the characteristics of workers and jobs, and firms face adjustment costs in responding to these variations. Matches and separations are described...

This paper indicates that East Germany’s unemployment originates primarily in the labor market, caused by the fast wage adjustment after German reunification. We model the resulting labor market traps in a search and matching framework, show that they are difficult to overcome, and provide...

This paper provides a theoretical and quantitative analysis of various types of wellknown employment subsidies. Two important questions are addressed: (i) How should employment subsidies be targeted? (ii) How large should the subsidies be? We consider measures involving targeting workers with...

Die Hartz-Reformen stellten zweifelsohne eine bedeutende Wende in der Entwicklung des Arbeitsmarktes dar. Obwohl die Reformen aus vier Teilen bestanden, war es hauptsächlich die Hartz-IV-Reform, die zu intensiven politischen und öffentlichen Debatten führte. Andrey Launov und Klaus Wälde...

The Hartz IV labour market reform in 2005 triggered a substantial reduction in unemployment in Germany. At the same time, it reduced social welfare for the long-term unemployed and increased uncertainty for the employed. The proposed reform by the new government ("Bürgergeld") will adjust the...

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...
