Standard search models are inconsistent with the amount of frictional wage dis- persion found in U.S. data. We resolve this apparent puzzle by modeling skill development (learning by doing on the job, skill loss during unemployment) and duration dependence in unemployment benefits in a random on...

Using life cycle publication data of 9,368 economics PhD graduates from 127 U.S. institutions, we investigate how unemployment in the U.S. economy prior to starting graduate studies and at the time of entry into the academic job market affect economics PhD graduates' research productivity. We...

This paper analyzes the effectiveness of social capital in reducing the negative externalities associated with stress, as well as the physical and psychological strain indicators among police officers. Despite the fact that there is a large multidisciplinary literature on stress or on social...

The purpose of this study was to investigate the determinants of police officers' intentions to quit their current department. For this purpose, we analysed US survey data that included a large set of police officers from the Baltimore Police Department in Maryland. Our results indicate that...

The US labour market is characterized by a high skill wage mark-up and low unemployment, while the German labour market has a low skill wage mark-up and a high, mainly unskilled unemployment rate. This paper adds an innovative labour supply explanation to the discussion how these distinct labour...

We develop a model of an economy with several regions, which differ in scale. Within each region, workers have to search for a job-type that matches their skill. They face a trade-off between match quality and the cost of extended search. This trade-off differs between regions, because search is...

How valuable are cognitive and social abilities for entrepreneurs’ incomes as compared to employees? We answer three questions: (1) To what extent does a composite measure of ability affect an entrepreneur's earnings relative to employees? (2) Do different cognitive abilities (e.g. math...

This paper first documents the increase in the time lag with which labor input reacts to output fluctuations (the labor adjustment lag) that is visible in US data since the mid-1980s. We show that a lagged labor adjustment response is optimal in a setting where there is uncertainty about the...

How valuable is education for entrepreneurs’ performance as compared to employees’? What might explain any differences? And does education affect peoples’ occupational choices accordingly? We answer these questions based on a large panel of US labor force participants. We show that...
