This paper proposes a framework that subsumes the two-way fixed effects as a special case to conduct causal inference with a continuous treatment. Treatments are allowed to change over time and potential outcomes are dependent on historical treatments. Regression models on potential outcomes, along with the sequentially conditional independence assumptions (SCIAs) are introduced to identify the treatment effects, which are measured by aggregate average causal responses. We also propose to test the validity of the SCIAs with directed acyclic graphs (DAGs). |
