Qualification: Beyond Random Assignment: Credible Inference of Causal Effects in Dynamic Economies

Record: kaal:position:2026-08-08-330 · 2026-08-08

Hennessy and Strebulaev sharpen the inference boundary. Their model treats government policy as an independent stochastic process, which allows them to abstract from endogeneity bias. Yet they show that random assignment alone does not make measured treatment responses equal causal effects in dynamic economies. Additional identifying assumptions remain necessary. This qualification supports holding work assignment fixed when the objective is to separate an institution's effect on outcomes from its effect on work selection. It does not establish that the matched condition identifies every causal effect. The paper studies dynamic policy environments, not multi-model agents, validation pools, or Kaal's registered cohort. Its contribution is narrower: controlling assignment can remove one selection channel without resolving every source of causal bias.

Affirmed commentary position. This record extends a source-bound scholarly claim but is not a verbatim paper claim.
