我们展示了如何将受试者随机分配到某个治疗组与对照组的评估数据与非实验方法相结合，以估计替代治疗的差异效应。我们提出了这些方法的有效性测试。我们使用这些方法和测试来分析劳动力附着（LFA）与人力资本开发（HCD）的培训组件与数据从加州的大大道独立（GAIN）计划的差异效应。虽然LFA在短期内比HCD培训更有效，但我们发现HCD在长期内相对更有效。
We show how data from an evaluation in which subjects are randomly assigned to some treatment versus a control group can be combined with nonexperimental methods to estimate the differential effects of alternative treatments. We propose tests for the validity of these methods. We use these methods and tests to analyze the differential effects of labor force attachment (LFA) versus human capital development (HCD) training components with data from California's Greater Avenues to Independence (GAIN) program. While LFA is more effective than HCD training in the short term, we find that HCD is relatively more effective in the longer term.
