A Reappraisal of the Virtues of Private Sector Employment Programmes*
评估了丹麦福利领取者参与私营部门就业计划的效果，发现平均处理效应不显著，但存在异质性，最可能参与的人反而受益最少。
This paper evaluates the employment effects of active labour market programmes for Danish welfare benefit recipients, focusing on private sector employment (PSE) programmes. Using a latent variable model that allows for heterogeneous treatment effects among observationally identical persons, we estimate commonly defined mean treatment effects and the distribution of treatment effects. We find no significant mean treatment effect of PSE programme participation as compared to participation in other programmes for PSE programme participants. However, we find substantial heterogeneity in the treatment effects, and those most likely to participate in PSE programmes are those who benefit the least from such programmes.
