Conditional average treatment-effects estimation using Stata

Free1 HourOnline

Treatment effects estimate the causal effects of a treatment on an outcome. We usually estimate average treatment effects (ATE), but taking an average across a population may not be useful when the effect is heterogeneous. Average treatment effects conditional on a set of variables (CATEs) help us understand heterogeneous treatment effects, and, by construction, are useful to evaluate how different treatment-assignment policies affect different groups in the population.

In this webinar, we will show how to use Stata 19's new command cate to answer questions such as the following:

  • Are the treatment effects heterogeneous?
  • How do the treatment effects vary with some variables?
  • Do the treatment effects vary across prespecified groups?
  • Are there unknown groups in the data for which treatment effects differ?
  • Which is best among possible treatment-assignment rules?
