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...

This paper examines critically the system of industry-level wage bargaining in Germany. More specifically, it shows that the importance of industry-level wage bargaining declines in Germany and that one major reason for this development is the highly restrictive institutional framework. However,...

Die Bekämpfung der Arbeitslosigkeit genießt oberste wirtschaftspolitische Priorität - dieser Feststellung wird kaum jemand widersprechen wollen. Eher scheiden sich die Geister an der Frage nach dem "wirklichen" quantitativen Ausmaß der Unterbeschäftigung, ihren Ursachen und welche...

Nineteenth-Century Catholic doctrine strongly opposed state schooling. We show that countries with larger shares of Catholics in 1900 (but without a Catholic state religion) tend to have larger shares of privately operated schools even today. We use this historical pattern as a natural...

Teachers differ greatly in how much they teach their students, but little is known about which teacher attributes account for this. We estimate the causal effect of teacher subject knowledge on student achievement using within-teacher within-student variation, exploiting a unique Peruvian...

The general-equilibrium effects of performance-related teacher pay include long-term incentive and teacher-sorting mechanisms that usually elude experimental studies but are captured in cross-country comparisons. Combining country-level performance-pay measures with rich PISA-2003 international...

Even though some countries track students into differing-ability schools by age 10, others keep their entire secondary-school system comprehensive. To estimate the effects of such institutional differences in the face of country heterogeneity, we employ an international...

We estimate the relationship between students? educational achievement and the availability and use of computers at home and at school in the international student-level PISA database. Bivariate analyses show a positive correlation between student achievement and the availability of computers...
