Hildalgo, D., Oosterbeek, H. and Webbink, D. (2014). The Impact of Training Vouchers on Low-skilled Workers Labour Economics, 31:117--128.

This paper reports about a randomized experiment in which training vouchers of €1000 were given to low-skilled workers. The vouchers increase training participation by almost 20 percentage points in two years, relative to a base rate of 0.45. This increased participation comes at a substantial deadweight loss of almost 60%. Consistent with predictions from human capital theory, we find that vouchers cause a shift towards more general forms of training. We do not find any significant impact of the program on monthly wages or on job mobility. The program does, however, have a significant impact on future training plans. Compared to always-takers, new trainees are more often male, more risk averse, work shorter hours and are less likely to have participated in training prior to treatment. Compared to never-takers, they are more often female, work longer hours and have a somewhat lower formal education level.
