In this article, we describe the use of ivmediate, a new command to estimate causal mediation effects in instrumental-variables settings using the framework developed by Dippel et al. (2020, unpublished manuscript). ivmediate allows estimation of a treatment effect and the share of this effect that can be attributed to a mediator variable. While both treatment and mediator can be potentially endogenous, a single instrument suffices to identify both the causal treatment and the mediation effects.

工具变量回归中的因果中介分析

在本文中，我们描述了ivmediate的使用，该新命令使用Dippel等人开发的框架来估计工具变量设置中的因果中介作用。（2020年，未出版的手稿）。ivmediate可以估计治疗效果以及可以归因于介体变量的这种效果的份额。尽管治疗和介导物都可能是内源性的，但只需一台仪器即可确定因果关系和介导作用。
