This paper analyses the performance of migrants on the German labour 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...

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...

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 topic is to focus on the firm level by estimating...

Are regions within a country really independent islands? Do economic relations and effects really have a homogenous, unique size across an entire country? These two assumptions are often imposed implicitly in empirical economic and social research. In his doctoral thesis, Norbert Schanne...

The labour-market policy-mix in Germany is increasingly being decided on a regional level. This requires additional knowledge about the regional development which (disaggregated) national forecasts cannot provide. Therefore, we separately forecast employment for the 176 German labour- market...

Was macht Gründungen aus Arbeitslosigkeit anders?' Um diese Frage zu beantworten, entwickeln wir einen theoretischen Ansatz für die Gründungsaktivität aus Arbeitslosigkeit. Weiterhin schätzen wir räumlich-autoregressive Modelle für die regionalen Gründungsraten aus Arbeitslosigkeit und...

Die Arbeitslosigkeit für die 176 deutschen administrativen Arbeitsmarktregionen (im Allgemeinen Arbeitsagenturbezirke) wird auf einer monatlichen Basis prognostiziert. Wegen ihrer geringen Größe existieren zwischen diesen regionalen Einheiten starke räumliche Interdependenzen. Um diese und...

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 in the Rhine-Ruhr metropolitan area, which is Germany's largest (and EU's second...

Labour-market policies are increasingly being decided on a regional level. This implies that institutions have an increased need for regional forecasts as a guideline for their decision-making process. Therefore, we forecast regional unemployment in the 176 German labour market districts. We use...
