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...

How does persecution affect who migrates? We analyze migrants' self-selection out of the USSR and its satellite states before and after the collapse of Communism using census microdata from the three largest destination countries: Germany, Israel, and the United States. We find that migrants...

What are the impacts of labor tax reform on wage setting and employment to keep the relative tax burden per low-skilled and high-skilled workers constant in the case of heterogenous domestic labor markets, i.e. imperfect competition in low-skilled labor and perfect competition in high-skilled...

We compile large datasets from Norwegian and US historical censuses to study return migration during the Age of Mass Migration (1850-1913). Return migrants were somewhat negatively selected from the migrant pool: Norwegian immigrants who returned to Norway held slightly lower-paid occupations...

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...

This paper investigates the empirical relevance of different unemployment theories in three major economies, namely the UK, the US and Japan, by estimating the degree of dependence in the unemployment series. Both univariate and multivariate long memory methods are used. The results vary...

We study the various consequences of and the incentives for outsourcing. We argue that the wage elasticity of labour demand increases as a function of the share of outsourcing, which is a result consistent with existing empirical research. Furthermore, we show that a production mode with a...

We evaluate the effects of outsourcing and wage solidarity on wage formation and equilibrium unemployment in a heterogeneous labour market, where wages are determined by a monopoly labour union. We find that outsourcing promotes the wage dispersion between the high-skilled and low-skilled...

We analyze the following questions associated with outsourcing and profit sharing under imperfect labour markets. How does strategic outsourcing influence wage formation, profit sharing and employee effort when firms commit to optimal profit sharing before wage formation or decide for profit...
