Econometrics Paper
Inference for instrumental variable regression with many weak instruments and many exogenous regressors

Yukitoshi Matsushita and Taisuke Otsu

This paper proposes inference methods for structural parameters in instrumental variable regression models that are robust to many and arbitrarily weak instruments and many included exogenous regressors. This setting is ...Read more...

Econometrics Paper
Causal inference with auxiliary observations

Takahiro Hoshino, Yuta Ota and Taisuke Otsu

In the evaluation of social programs, it is often difficult to conduct randomized controlled experiments due to non-compliance; therefore the local average treatment effect (LATE) is commonly applied. However, LATE...Read more...

Econometrics Paper
Geodesic causal inference

Daisuke Kurisu, Hans-Georg Mueller, Taisuke Otsu and Yidong Zhou

Adjusting for confounding and imbalance when establishing statistical relationships is an increasingly important task, and causal inference methods have emerged as the most popular tool to achieve this. Causal inference ...Read more...

Econometrics Paper
Likelihood ratio inference for missing data models

Karun Adusumilli and Taisuke Otsu

Missing or incomplete outcome data is a ubiquitous problem in biomedical and social sciences. Under the missing at random setup, inverse probability weighting is widely applied to estimate and make inference on the popul...Read more...

Eliciting and Utilizing Willingness-to-pay: Evidence from Field Trials in Northern Ghana

James Berry, Greg Fischer and Raymond Guiteras

Using the Becker-DeGroot-Marschak (BDM) mechanism, we estimate the willingness-to-pay (WTP) for and impact of clean water technology through a field experiment in Ghana. Although WTP is low relative to the cost, demand ...Read more...

Econometrics Paper
Information theoretic approach to high dimensional multiplicative models: Stochastic discount factor and treatment effect

Taisuke Otsu and Chen Qiu

This paper is concerned with estimation of functionals of a latent weight function that satisfies possibly high dimensional multiplicative moment conditions. Main examples are missing data problems, treatment effects, an...Read more...

Econometrics Paper
Bootstrap inference of matching estimators for average treatment effects

Taisuke Otsu and Yoshiyasu Rai

Abadie and Imbens (2008) showed that the standard naive bootstrap is inconsistent to estimate the distribution of the matching estimator for treatment effects with a fixed number of matches. This article proposes an asym...Read more...

Econometrics Paper
Asymptotic Expansions for Some Semiparametric Program Evaluation Estimators

Hidehiko Ichimura and Oliver Linton

We investigate the performance of a class of semiparametric estimators of the treatment effect via asymptotic expansions. We derive approximations to the first two moments of the estimator that are valid to 'second order...Read more...
