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 difference in differences. ...
This paper develops a generalization of the widely used difference-in-differences method for evaluating the effects of policy changes. We propose a model that allows the control and treatment groups to have different average benefits from the treatment. The assumptions of the proposed model are invar...
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...
This study investigates the spatial spillover effects of the CET policy on industrial carbon intensity reduction by developing spatial difference-in-differences (SDID) models. Then, a mediating effect model is used to test whether technological progress is a mediating variable of the spillover ...
