Inference on a New Class of Sample Average Treatment Effects

FINITE-SAMPLE OPTIMAL ESTIMATION AND INFERENCE ON AVERAGE TREATMENT EFFECTS UNDER UNCONFOUNDEDNESS By

We consider estimation and inference on average treatment effects under unconfoundedness conditional on the realizations of the treatment variable and covariates. We derive finite-sample optimal estimators and confidence intervals (CIs) under the assumption of normal errors when the conditional mean of the outcome variable is constrained only by nonparametric smoothness and/or shape restriction...

Finite-Sample Optimal Estimation and Inference on Average Treatment Effects Under Unconfoundedness∗

We consider estimation and inference for average treatment effects, where coverage is required conditional on treatments and pretreatment variables. We derive finitesample optimal estimators and confidence intervals (CIs) under the assumption of normal errors when the conditional mean of the outcome variable is constrained only by nonparametric smoothness and/or shape restrictions. If the smoot...

Finite Sample Properties of Semiparametric Estimators of Average Treatment Effects∗

We explore the finite sample properties of several semiparametric estimators of average treatment effects, including propensity score reweighting, matching, double robust, and control function estimators. When there is good overlap in the distribution of propensity scores for treatment and control units, reweighting estimators are preferred on bias grounds and attain the semiparametric efficien...

effects of first language on second language writing-a preliminary contrastive rhetoric study of farsi and english

to explore the idea the investingation proposed, aimed at finding whether the performances of the population of iranians students studying english in an efl context are consistent in l1 and l2 writing taks and whether there is a cross-linguistic transfer in this respect. in this regard the subjects were instructed to write four compositions-two in english and two in farsi-which consisted of an ...
