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...

Using a state panel based on census data from 1940-2010, I examine the impact of immigration on the high school completion of natives in the United States. Immigrant children could compete for schooling resources with native children, lowering the return to native education and discouraging...

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...

This paper seeks to empirically identify factors that influence the probability of being a fast growing firm in Eastern and Western Germany. Descriptive analyses have shown that most firms experience only small positive or negative employment growth or stagnate over time. The job generation...
