Little is known about the payoffs to apprenticeship training in the German speaking countries for the participants. There is a lot of heterogeneity in the types of apprenticeships offered, and there might be an important element of selection in who obtains an apprenticeship, and what type. To...

We examine the relationship between the employment and compensation of managers and CEOs and the presence of a unionized workforce. We develop a simple efficiency wage model, with a tradeoff between higher wages for workers and more monitoring, which requires more managers. The model also...

Becker?s theory of human capital predicts that minimum wages should reduce training investments for affected workers because they prevent these workers from taking wage cuts necessary to finance training. In contrast, in noncompetitive labor markets, minimum wages tend to increase training of...

An emerging economic literature over the past decade has made use of international tests of educational achievement to analyze the determinants and impacts of cognitive skills. The cross-country comparative approach provides a number of unique advantages over national studies: It can exploit...

This paper analyses the compensatory behavior of smokers. Exploiting data on cotinine concentration a metabolite of nicotine measured in a large population of smokers over time, we show that smokers compensate tax hikes by extracting more nicotine per cigarette. Our study makes two important...

This paper shows that smoking intensity, i.e. the amount of nicotine extracted per cigarette smoked, responds to changes in excise taxes and tobacco prices. We exploit data covering the period 1988 to 2006 across many US states. Moreover, we provide new evidence on the importance of cotinine...

We estimate the effect of class size on student performance in 18 countries, combining school fixed effects and instrumental variables to identify random class-size variation between two adjacent grades within individual schools. Conventional estimates of class-size effects are shown to be...

We investigate whether a causal interpretation of the robust association between cognitive skills and economic growth is appropriate and whether cross-country evidence supports a case for the economic benefits of effective school policy. We develop a new common metric that allows tracking...
