This paper proposes new estimators for the propensity score that aim to maximize the covariate distribution balance among different treatment groups. Heuristically, our proposed procedure attempts to estimate a propensity score model by making the underlying covariate distribution of different treatment groups as close to each other as possible. Our estimators are data-driven, do not rely on tuning parameters such as bandwidths, admit an asymptotic linear representation, and can be used to… Expand
Doubly Robust Difference-in-Differences Estimators
This article proposes doubly robust estimators for the average treatment effect on the treated (ATT) in difference-in-differences (DID) research designs. In contrast to alternative DID estimators,Expand
A Unified Framework for Specification Tests of Continuous Treatment Effect Models
We propose a general framework for the specification testing of continuous treatment effect models. We assume a general residual function, which includes the average and quantile treatment effectExpand


Covariate balancing propensity score by tailored loss functions
In observational studies, propensity scores are commonly estimated by maxi- mum likelihood but may fail to balance high-dimensional pre-treatment covariates even after specification search. WeExpand
Improving Covariate Balancing Propensity Score : A Doubly Robust and Efficient Approach ∗
Inverse probability of treatment weighting (IPTW) is a popular method for estimating causal effects in many disciplines. However, empirical studies show that the IPTW estimators can be sensitive toExpand
Globally efficient non-parametric inference of average treatment effects by empirical balancing calibration weighting.
The results show that efficiency can be achieved by solely balancing the covariate distributions without resorting to direct estimation of propensity score or outcome regression function, and the proposed variance estimator outperforms existing estimators that require a direct approximation of the efficient influence function.

Balancing Covariates via Propensity Score Weighting
ABSTRACT Covariate balance is crucial for unconfounded descriptive or causal comparisons. However, lack of balance is common in observational studies. This article considers weighting strategies forExpand
Matching on the Estimated Propensity Score
Propensity score matching estimators (Rosenbaum and Rubin (1983)) are widely used in evaluation research to estimate average treatment effects. In this article, we derive the large sampleExpand
Efficient Estimation of Average Treatment Effects Using the Estimated Propensity Score
We are interested in estimating the average effect of a binary treatment on a scalar outcome. If assignment to the treatment is unconfounded, that is, independent of the potential outcomes givenExpand
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. Expand
The Role of the Propensity Score in Estimating Dose-Response Functions
Estimation of average treatment effects in observational, or non-experimental in pre-treatment variables. If the number of pre-treatment variables is large, and their distribution variesExpand
Specification tests for the propensity score
This paper derives a particular restriction relating the propensity score distribution of treated and control groups, and develops specification tests based upon it that do not suffer from the "curse of dimensionality", are fully data-driven, and do not require tuning parameters such as bandwidths.

Reducing Bias in Observational Studies Using Subclassification on the Propensity Score
Abstract The propensity score is the conditional probability of assignment to a particular treatment given a vector of observed covariates. Previous theoretical arguments have shown thatExpand
