This paper develops a machine-learning method that allows researchers to estimate heterogeneous treatment effects with … causal-forest method of Wager and Athey (2018) by allowing for the estimation of dynamic treatment effects in a difference …-in-difference setting. Regular causal forests require conditional independence to consistently estimate heterogeneous treatment effects. In …
