The need for graduates who would be productive citizens able to contribute significantly to the Nigerian economy led to the overhaul of the old education system 6-5-4 and the implementation of the 6-3-3-4 system, with its first set of graduates from secondary schools in 1988. The main objective...

We present a meta-analysis of impact estimates from over 200 recent econometric evaluations of active labor market programs from around the world. We classify estimates by program type and participant group, and distinguish between three different post-program time horizons. Using meta-analytic...

We study the effects of a Danish wage subsidy program for highly educated workers on the labor market outcomes of the persons participating in the program and on the performance of the firms that hired these subsidized workers. Using data on the population of program participants, both...

We consider treatment effect estimation via a difference-in-difference approach for data with local spatial interaction such that the outcome of observed units depends on their own treatment as well as on the treatment status of proximate neighbors. We show that under standard assumptions...

This paper proposes a new framework for analyzing the effects of sequences of treatments with duration outcomes. Applications include sequences of active labor market policies assigned at specific unemployment durations and sequences of medical treatments. We consider evaluation under...

We derive nonparametric sharp bounds on average treatment effects with an instrumental variable (IV) and use them to evaluate the effectiveness of the Job Corps (JC) training program for disadvantaged youth. We concentrate on the population average treatment effect (ATE) and the average...

This paper analyzes the returns to training that was co-financed by the German voucher program "Bildungsprämie". The estimation strategy compares outcomes of participants in voucher training with voucher recipients who intended to participate in training, but did not do so because of a random...
