We build an analytically and computationally tractable stochastic equilibrium model of unemployment in heterogeneous labor markets. Facing search frictions within markets and reallocation frictions between markets, workers endogenously separate from employment and endogenously reallocate between...

We analyse optimal saving of risk-averse households when labour income stochastically jumps between two states. The generalized Keynes-Ramsey rule includes a precautionary savings term. A phase diagram analysis illustrates consumption and wealth dynamics within and between states. There is an...

Das Hamburger Modell zur Beschäftigungsförderung zielt darauf ab, Arbeitslose mit geringen Verdienstmöglichkeiten und schlechten Arbeitsmarktchancen durch zeitlich befristete Zuschüsse, die sowohl den Teilnehmern an der Maßnahme als auch den Arbeitgebern gewährt werden, in den regulären...

Often the high level of unemployment in Germany is explained by a lack of flexibility, over-regulation in the labour market and disincentives of the social security system. However, these institutional effects are difficult to test by means of data from only one country. Cross-country...

This paper analyzes the importance of time aggregation in the measurement of worker flows by exploiting daily information from German administrative data. Time aggregation caused by comparing monthly labor market states leads to an underestimation of total worker flows by around 10%. Contrary to...

Does the low wage sector serve as a stepping stone towards integration into better-paid jobs or at least towards integration of jobless people into employment? There is evidence for a 'low-wage trap' and for a high risk of low-wage earners to get unemployed, but this may also be due to sorting...

A wide class of models with On-the-Job Search (OJS) predicts that workers gradually select into better-paying jobs. We develop a simple methodology to test predictions implied by OJS using two sources of identification: (i) time-variation in job-finding rates and (ii) the time since the last...

We consider a model of on-the-job search where firms offer long-term wage contracts to workers of different ability. Firms do not observe worker ability upon hiring but learn it gradually over time. With sufficiently strong information frictions, low-wage firms offer separating contracts and...

To many economists the public's support for the minimum wage (MW) institution is puzzling, since the MW is considered a “blunt instrument” for redistribution. To delve deeper in this issue we build models in which workers are heterogeneous in ability. In the first model, the government does...

We analyze the following question associated with flexible outsourcing under imperfect domestic labour market: How does the implementation of profit sharing influence flexible outsourcing? We show that in general profit sharing has a negative effect on low skilled wage and thus an outsourcing...
