当前常用的处理方式由如下三种:倾向得分匹配(Propensity Score Matching,PSM)、三重差分法(Difference-in-differences-in-differences, DDD)、合成控制法(Synthetic Control Method)。可以理解为人工构建相对同质的实验组和对照组的方法。 3 同质化人群的构建方法 通过构建相对的同质人群使满足平行趋势假设 3.1 倾向得分匹...
We lay out the theory underlying SDID both when there is a single treatment adoption date and when adoption is staggered over time, and we discuss estimation and inference in each of these cases. We introduce the sdid command, which implements these methods in Stata, and provide several ...

Difference in difference in differences (DDD) adds a control group to the DID framework to account for unobservables group- and time-characteristic interactions that might not be captured by DID. It augments DID with another difference for the new control group. Hence, the name difference in dif...
