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 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...

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 estimates the effect of graduating from college on lifetime earnings. Motivated by the fact that nearly half of all college students fail to earn a bachelor’s degree, we study a model of risky college completion. The central idea is that students drop out of college mainly because...

This paper is motivated by the fact that nearly half of U.S. college students drop out without earning a bachelor's degree. Its objective is to quantify how much uncertainty college entrants face about their graduation outcomes. To do so, we develop a quantitative model of college choice. The...

Using data from the 2006 wave of the German Socio-Economic Panel (GSOEP), this paper analyzes how a minimum wage affects employment, wage inequality, public expenditures, and aggregate income in the low-wage sector. It is shown that a statutory minimum wage of EUR 7.50 per hour would cost...

Do minimum wages reduce in-work-poverty and wage inequality? Or can alternative policies do better? We evaluate theses issues for the exemplary case of Germany that suffers from high unemployment among low-skilled workers and rising wage dispersion at the bottom of the wage distribution. We...

The fraction of persons holding a college degree differs nearly two-fold across U.S. states. This paper documents data related to state educational attainment differences and explores possible explanations. It shows that highly educated states employ skillbiased technologies, specialize in...
