Standard economic theory predicts that firms will not invest in general training and will underinvest in specific training. Empirical evidence, however, indicates that firms do invest in general training of their workers. Evidence from laboratory experiments points to less underinvestment in...

This is illustrated by government student loans...</p></a>

This paper explores the hypothesis that wage differentials between skill groups across countries are consistent with a demand and supply framework. Using micro data from 15 countries we find that about one third of the variation in relative wages between skill groups across countries is...

In a randomized field experiment where first year university students could earn financial rewards for passing all first year requirements within one year we find small and non-significant average effects of financial incentives on the pass rate and the numbers of collected credit points. There...

This paper reports about a randomized field experiment in which first year economics and business students at the University of Amsterdam could earn financial rewards for passing the first year requirements within one year. Participants were assigned to a high, low and zero (control) reward...

This paper estimates peer effects originating from the ability composition of tutorial groups for undergraduate students in economics. We manipulated the composition of groups to achieve a wide range of support, and assigned students – conditional on their ability – randomly. The data...

This paper estimates the effects of attending medical school on health outcomes by exploiting that admission to medical school in the Netherlands is determined by a lottery. Among the applicants for medical school, people who attended medical school have on average 1.5 more years of completed...

This paper follows an alternative approach to identify the wage effects of private-sector training. The idea is to narrow down the comparison group by only taking into consideration the workers who wanted to participate in training but did not do so because of some random event. This makes the...
