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 looks at the impact of networks on international migration flows to OECD countries. In particular, we look at whether diaspora effects are different across education levels and gender. Using new data allowing to include both dimensions, we are able to analyze the respective impact of...

We provide evidence that the robust association between cognitive skills and economic growth reflects a causal effect of cognitive skills and supports the economic benefits of effective school policy. We develop a new common metric that allows tracking student achievement across countries, over...

Existing migrant networks play an important role in explaining the size and structure of immigration flows. They affect the net benefits of migration for future migrants by lowering assimilation costs ('self-selection' channel) and increase the probability of potential migrants to obtain a visa...

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...

We argue in favor of the shareholder model of the firm for three main reasons. First, serving multiple stakeholders leads to ill-defined property rights. What sounds like a fair compromise between stakeholders can easily evolve in a permanent struggle about the ultimate goal of the company....

This paper analyses monthly hours worked in the US over the sample period 1939m1 - 2011m10 using a cyclical long memory model; this is based on Gegenbauer processes and characterised by autocorrelations decaying to zero cyclically and at a hyperbolic rate along with a spectral density that is...

At the turn of the millennium three frequently cited potential causes of new challenges for wage policy in Germany are revisited in this study: skilled-biased technological progress, the increasing international integration of labor and product markets, and the monetary integration of the EMU....

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...
