We formulate a econometric framework for studying treatment effects on discrete outcomes when the treatment effects are heterogeneous and the unobserved heterogeneity is given by a factor structure. Within this framework, we show how to define and semiparametrically estimate the average...

In this paper we evaluate a Norwegian vocational rehabilitation program by comparing employment outcomes of trainees and nonparticipants using nonexperimental data. A matching estimator is used to calculate the training effect for different subgroups of the sample. We demonstrate how bounding...

In this paper we evaluate the effectiveness of labour market training programmes in raising participants employment rates. Detailed pre-training and post-training information on background variables, earnings and employment are used to estimate the training effect.

In this paper we evaluate a Norwegian vocational rehabilitation program by comparing employment outcomes of trainees and nonparticipants using nonexperimental data. A matching estimator based on the propensity score is used to calculate the training effect for different subgroups of the sample.
