Uniformly Semiparametric Efficient Estimation of Treatment Effects With a Continuous Treatment
连续处理效应的一致半参数有效估计
This article studies identification, estimation, and inference of general unconditional treatment effects models with continuous treatment under the ignorability assumption. We show identification of the parameters of interest, the dose–response functions, under the assumption that selection to treatment is based on observables. We propose a semiparametric two-step estimator, and consider estimation of the dose–response functions through moment restriction models with…
