The secular shift in labor demand from unskilled to skilled labor is explained within a model that is solved numerically. There are three branches producing a basic good, a differentiated luxury good, and an intermediate service. Production is more skill-intensive in the luxury good and the...

We explore the far-reaching implications of low-wage subsidies on aggregate employment. Low-wage subsidies have three important effects. First, they promote employment of unskilled workers (who tend to be the ones who earn low wages). Second, by raising the payoff of unskilled work relative to...

Recent studies have shown that there are significant earnings differentials between immigrants and natives in Switzerland. The goal of this paper is to determine whether these differences can be attributed to diverging socio-economic endowments or to discrimination. We use the well-known...

In this paper, I discuss three sets of links which I uncover in the data on aggregate US job and worker flows. Job flows are strongly related to aggregate employment growth, while worker flows are strongly related to employment growth and the unemployment rate. I show that a simple frictionless...

This paper analyzes the role of the extensive vis-à-vis the intensive margin of labor adjustment in Germany and in the United States. The contribution is twofold. First, we provide an update of older U.S. studies and confirm the view that the extensive margin (i.e., the adjustment in the number...

Does immigration accelerate sectoral change towards high-productivity sectors? This paper uses the mass displacement of ethnic Germans from Eastern Europe to West Germany after World War II as a natural experiment to study this question. A simple two-sector model of the economy, in which moving...

This paper develops a Heckscher-Ohlin-type framework in which relative factor prices are affected by output prices as well as by total factor productivity growth. The empirical analysis finds no evidence that the relative prices of unskilled-labour- intensive manufactures, adjusted for total...

This paper is based on my thesis from the year 2008. It uses the German Microcensus (MC) to study the effects of continuing vocational training (CVT) on employment, the risk of unemployment, and wages. To control for education, profession and heterogeneity in the sectors and industrial branches...

This paper studies the impact of outsourcing on individual wages in three European countries with markedly different labour market institutions: Germany, the UK and Denmark. To do so we use individual level data sets for the three countries and construct comparable measures of outsourcing at the...

Since there is scant evidence on the role of industrial relations in wage cyclicality, this paper analyzes the effect of collective wage contracts and of works councils on real wage growth. Using linked employer-employee data for western Germany, we find that works councils affect wage growth...
