We consider a functional parameter called the conditional average treatment effect (CATE), designed to capture the heterogeneity of a treatment effect across subpopulations when the unconfoundedness assumption applies. In contrast to quantile regressions, the subpopulations of interest are defined in terms of the possible values of a set of continuous covariates rather than the quantiles of the potential outcome distributions. We show that the CATE parameter is nonparametrically identified…

Estimation of Conditional Average Treatment Effects With High-Dimensional Data

Abstract Given the unconfoundedness assumption, we propose new nonparametric estimators for the reduced dimensional conditional average treatment effect (CATE) function. In the first stage, the…

The role of propensity score structure in asymptotic efficiency of estimated conditional quantile treatment effect

When a strict subset of covariates is given, we propose conditional quantile treatment effect ( CQTE ) to offer, compared with the unconditional quantile treatment effect ( QTE ) and conditional…

Estimation of Partially Conditional Average Treatment Effect by Hybrid Kernel-covariate Balancing

A hybrid kernel weighting estimator where the weights aim to control the balancing error of any function of the confounders from a reproducing kernel Hilbert space after kernel smoothing over the subset of interested variables is proposed.

Outcome regression-based estimation of conditional average treatment effect

The research is about a systematic investigation on the following issues. First, we construct different outcome regression-based estimators for conditional average treatment effect under,…

Nonparametric Tests for Treatment Effect Heterogeneity With Duration Outcomes

This article proposes different tests for treatment effect heterogeneity when the outcome of interest, typically a duration variable, may be right-censored and can detect nonparametric alternatives converging to the null at the parametric $n^{-1/2}$-rate, $n$ being the sample size.

An IV estimator for a functional coefficient model with endogenous discrete treatments

Abstract We propose instrumental variables (IV) estimators for averaged conditional treatment effects and the parameters upon which they depend in the context of a semiparametric outcome model with…

Abstract We propose a new treatment effect parameter called the quantile structural treatment effect (QSTE) to distinguish between observed and unobserved treatment heterogeneity in the…

Distribution and Quantile Structural Functions in Treatment Effect Models: Application to Smoking Effects on Wages

This paper examines the distribution structural functions (DSFs) and quantile structural functions (QSFs) in a semiparametric treatment effect model. The DSF and QSF are defined as the distribution…

Efficient Estimation of Average Treatment Effects Using the Estimated Propensity Score

It is shown that weighting with the inverse of a nonparametric estimate of the propensity Score, rather than the true propensity score, leads to efficient estimates of the various average treatment effects, whether the pre-treatment variables have discrete or continuous distributions.
