We argue that policy evaluations using group-level longitudinal ("panel") data need to take a similar careful approach to study design, which we refer to as"policy trial emulation."This is especially important when intervention timing varies across jurisdictions; the main idea is to construct target trials separately for each"treatment cohort"(states that implement the policy at the same time) and then aggregate. 4 5 In this paper, we argue that policy evaluations using panel data need to take a similarly careful approach to study design, which we refer to as "policy trial emulation." The main idea is to construct target trials separately for each "treatment cohort" (states that implement the policy at the same time) and then aggregate.	./cache/cord-135406-ztgrxucb.txt	./txt/cord-135406-ztgrxucb.txt
