The estimation of BCP effect by the difference in differences method relies on the parallel trends assumption33, also known as the common trends assumption31: $$E\left[{Y}_{t}\left(\infty \right)-{Y}_{1}\left(\infty \right)|{\text{BCP}}\right]=E\left[{Y}_{t}\left(\infty \ri...
The difference-in-differences method takes the difference in outcomes before and after the treatment, the difference in outcomes in the period before and after in the control group, and then removes all time-varying factors from the first difference b...

双重差分法 ( Difference in differences,简称为 DID 或 DD ) 是用于估计处理效应的最为常见的计量方法,广泛应用于评估政策实施、项目执行及其他外生事件产生的效应。DID 法通过衡量处理组与控制组在被处理前后发生的变化,将处理组的变动减去控制组的变动,得到处理效应。由于在估计过程中采用了两次差分,故名为双重差...
