This paper investigates two mechanisms through which education may affect cognitive skills in adolescence: the role of instructional quantity and the timing ofinstruction with respect to age. To identify causal effects, I exploit a school reform carried out at the state level in Germany as a...

Anecdotal evidence suggests that the cost of child care in the U.S. has increased substantially over the past few decades. This paper marshals data from a variety of sources to rigorously assess the issue. It begins by using nationally representative survey data to trace the evolution in...

It is still taken for granted that (early) ability tracking increases the impact of social origin on achievement in (lower) secondary education, but without gains in the overall level. This contribution addresses the question of whether this common conviction is really correct. The various...

Concepts of new school governance did considerably change the role and responsibilities of school principals. Due to the shift in their role from administrator to manager, recent research tends to focus on management activity, but little is still known about the interrelation between changing...

Most studies find little to no effect of classroom computers on student achievement. We suggest that this null effect may combine positive effects of computer uses without equivalently effective alternative traditional teaching practices and negative effects of uses that substitute more...

Online education options have proliferated in recent years, with significant growth occurring at state-sponsored virtual schools. However, there is no prior credible evidence on the quality of virtual courses compared to in-person courses in U.S. secondary education. We compare the performance...

The research on earnings determination is based on the Mincer-Becker assumption that individuals decide on schooling by maximizing income. This paper offers an alternative and less restrictive approach based on utility maximization. Using this approach, we analyze the efficiency of education...
