This paper analyzes the performance of migrants on the German labor market and its dependence on the tasks performed on their jobs. Recent work suggests quantifying the imperfect substitutability relationship between migrants and natives as a measure for the hurdles migrants have to face. Our...

"Empirical evidence for the US shows that migrants increase the productivity of regions. To explain the impact of migrants on the average firm productivity we construct a general equilibrium model with monopolistic competition a la Melitz (2003). We consider heterogeneous firms with different...

Economic debate about the consequences of immigration in Germany has largely focused on the wage effects for natives at an aggregate level. Especially the role of imperfect substitutability of migrants and natives gained importance. A new micro oriented approach is to focus on the firm level by...

To examine the impact of migrants on the average firm productivity, wages and welfare we construct a general equilibrium model with monopolistic competition a la Melitz (2003) considering heterogeneous firms with different productivity levels and imperfect substitutability between migrants and...

"We forecast unemployment for the 176 German labour-market districts on a monthly basis. Because of their small size, strong spatial interdependencies exist between these regional units. To account for these as well as for the heterogeneity in the regional development over time, we apply...

"'What makes start-ups out of unemployment different?' To answer this question we formulate a theoretical sketch for start-up activity out of unemployment. Furthermore, we estimate spatial autoregressive models for the regional start-up rates out of unemployment as well as out of employment with...

This paper presents an outline of the so-called Shift-Share Regression and an application of this method to the analysis of employment development. The method used is not a deterministic decomposition such as the classical Shift-Share-Analysis, but a powerful, yet simple and flexible econometric...

Your very private job agency: Job referrals based on residential location networks This paper analyzes job referral effects that are based on residential location. We use georeferenced record data for the entire working population (liable to social security) and the corresponding establishments...
