This article presents identification results for the marginal treatment effect (MTE) when there is sample selection. We show that the MTE is partially identified for individuals who are always observed regardless of treatment, and derive uniformly sharp bounds on this parameter under three...

Short-term education and skills training programs are a popular way to meet the needs of unemployed, out-of-school youth by providing them with an opportunity to quickly acquire qualifications and skills that can lead to productive employment. This paper reviews the global evidence to identify...

We bound the distribution of treatment effects under plausible and testable assumptions on the joint distribution of potential outcomes, namely that potential outcomes are mutually stochastically increasing. We show how to test the empirical restrictions implied by those assumptions. The...
