Immigration policy in most high-income countries is designed to promote qualified migration while maintaining high requirements on characteristics such as education and language skills. We rely on a standard self-selection model with heterogeneous migration costs to discuss the effect of access...

I study the recruiting behaviour of German establishments with regard to the use of foreign labour markets. Applying instrumental variable strategies, I find foreign affinity and labour market scarcity to stimulate the use of foreign markets. Regional labour market scarcity is particularly...

We provide estimates of the effect of migrant labor supply on resident employment. We exploit variation in the number of asylum seekers eligible to the suspension of a major hiring restriction implemented in a subset of German counties. Our difference-in-difference design allows us to provide...

Population size and structure in conjunction with the participation behavior are the determinants of labor supply. Thereby, among the demographic components, migration is the one shaping both the size and the structure of a population the strongest in the short to medium term while...

In this paper, we assess the impact of international migration, and the induced home-care service labour supply shock, on fertility decisions and labour supply of native females in Germany. Specifcally, we consider individual data of native women from the German Socio-Economic Panel and we merge...

Theoretically, wage gaps between migrants and natives can be explained by human capital theory through either depreciation in human capital with migration or differences in endowments. However, even after considering human capital measures, an unexplained difference remains. We assume that...

Die Studie analysiert die theoretischen Auswirkungen von Mindestlöhnen auf Beschäftigung und Lohnspreizung in einem fluktuationsbedingten Szenario. Es wird ein Überblick über neue theoretische Forschungsansätze gegeben und der Einfluss von Mindestlöhnen auf Einkommen und Beschäftigung in...

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...

On December 8, 2024, the sudden collapse of Bashar al‑Assad's regime, abruptly changed Syria's political landscape and reshaped the return prospects for millions of Syrians living abroad. We exploit this unanticipated regime change as a natural experiment to estimate the causal impact of...
