This paper analyses worker transitions on the German labour market derived from different data sources. These include the two German micro data sets which provide high-frequency observations on workers' employment and unemployment histories: the German Socioeconomic Panel (SOEP) and the IAB...

We analyze a general search model with on-the-job search and sorting of heterogeneous workers into heterogeneous jobs. This model yields a simple relationship between (i) the unemployment rate, (ii) the value of non-market time, and (iii) the max-mean wage differential. The latter measure of...

As part of a more general process of employment reallocation from less to more productive employers, jobto- job flows tend to be beneficial for productivity and for workers. Thus, when this rate slows, it is important to understand why. In the US, for example, the job-to-job flow rate is now at...

An advantage of collective wage agreement is that search and business-stealing externalities can be internalized. A disadvantage is that it takes more time before an optimal allocation is reached because more productive firms (for a particular worker type) can no longer signal this by posting...

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...

One of the most important long-run trends in the U.S. labor market is polarization, defined as the relative growth of employment in high-skill jobs (such as management and technical positions) and low-skill jobs (such as food-service and janitorial work) amid the concurrent decline in...
