"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...

"Following microeconomic theory, every vacancy should be filled by appropriate manpower after a certain time. However, from an empirical point of view it is evident that vacancies remain unfilled as establishments cancel their search for a suitable applicant. The German Job Vacancy Survey (JVS)...

"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...

"In the last years the analysis of flow figures turned out to highly informative for labour market research and policy advice. Among researchers it is a well known fact that cross-sectional information about labour market is not sufficient to understand ungoing development. A pure sequence of...

"Despite the ongoing discussion on labor shortage in the German economy there is still a lack of empirical analyses of this problem based on adequate econometric methods. The paper explores the determinants of labor shortage in the environmental sector supplying products and services that help...

"Using a linked employer-employee dataset and taking the perspective of individuals rather than firms, this paper analyzes some effects of joining start-ups. We show that entrants in new firms differ from those joining incumbent firms, and we use a matching approach to compare a group of...

"We revisit the puzzling finding that labour market performance appears to deteriorate, as suggested by negative time trends in empirical matching functions. We investigate whether these trends simply arise from omitted variable bias. Concretely, we consider the omission of job seekers beyond...

"Wage subsidies are a major instrument of active labor market policies in Germany. This paper analyses for West Germany, if tenure differs across individuals taking up a subsidized or unsubsidized job, respectively, during the second quarter of 2003. The study is based on process generated data...
