This paper examines evidence on the effect of class size on student achievement. First, it is shown that results of quantitative summaries of the literature, such as Hanushek (1997), depend critically on whether studies are accorded equal weight. Hanushek summarizes 277 estimates extracted from...

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...

Little is known about the payoffs to apprenticeship training in the German speaking countries for the participants. OLS estimates suggest that the returns are similar to those of other types of schooling. However, there is a lot of heterogeneity in the types of apprenticeships offered, and...

We estimate peer effects for fourth graders in six European countries. The identification relies on variation across classes within schools. We argue that classes within primary schools are formed roughly randomly with respect to family background. Similar to previous studies, we find sizeable...
