Does a high regional concentration of immigrants of the same ethnicity affect immigrant children's acquisition of host-country language skills and educational attainment? We exploit the exogenous placement of guest workers from five ethnicities across German regions during the 1960s and 1970s in...

We investigate whether a causal interpretation of the robust association between cognitive skills and economic growth is appropriate and whether cross-country evidence supports a case for the economic benefits of effective school policy. We develop a new common metric that allows tracking...

What sounds like a fair compromise between stakeholders can easily evolve in a permanent struggle between the stakeholders about the ultimate...

We analyze a general search model with on-the-job search and sorting of heterogeneous workers into heterogeneous jobs. This model yields a simple relationship between (i) the unemployment rate, (ii) the value of non-market time, and (iii) the max-mean wage differential. The latter measure of...

Die Ergebnisse der multivariaten Analysen zur Beschäftigungsdynamik und dem Wachstumspotential junger innovativer Unternehmen lassen erkennen, daß junge innovative Unternehmen signifikant höhere Wachstumsraten erzielen als junge Unternehmen mit traditionellen Produkten. Die Abschätzung der...

The paper deals with growth determinants of innovative and noninnovative start-ups in Eastern and Western Germany. Based on theoretical approaches explaining the growth of firms, hypotheses on potential determinants are derived. The empirical results indicate strong correlations between average...
