We examine the effects of endogenous offshoring on cost-efficiency, wages and unemployment in a task-assignment model with skill heterogeneity. Exact conditions for the following insights are derived. The distributional effect of offshoring (high-) low-skill-intensive tasks is similar to...

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...

This paper investigates the time-varying relationship between German output and employment growth, in particular their decoupling in recent years. We estimate a correlated unobserved components model that allows for persistent and cyclical time variation in the employment-GDP linkage as well as...

Increasing wage inequality is associated with changes in the degree of labor market sorting, i.e. the allocation of workers to firms. To measure sorting, we propose a new method which disentangles the respective contributions of worker and firm heterogeneity to wage inequality. Inspired by...

In a structural macroeconometric analysis based on comprehensive micro data, we examine the role of skill-biased technical change for the flattening of productivity growth and effects on hours worked. The results show that more than 60 percent of the slowdown in productivity growth in Germany...

We review the literature on firm-level drivers of labor market inequality. There is strong evidence from a variety of fields that standard measures of productivity - like output per worker or total factor productivity - vary substantially across firms, even within narrowly-defined industries....
