Econometric Inference with Machine-Learned Proxies: Partial Identification via Data Combination
Lixiong Li
Empirical researchers increasingly use upstream machine-learning (ML) methods to construct proxies for latent target variables from complex, unstructured data. A naive plug-in use…
Identification and Counterfactual Analysis in Incomplete Models with Support and Moment Restrictions
Lixiong Li
This paper develops a unified identification framework for counterfactual analysis in incomplete models characterized by support and moment restrictions. I demonstrate that identif…
A Generalized Control Function Approach to Production Function Estimation
Ulrich Doraszelski, Lixiong Li
We develop a generalized control function approach to production function estimation. Our approach accommodates settings in which productivity evolves jointly with other unobservab…
Robust Counterfactuals in Centralized Schools Choice Systems: Addressing Gender Inequality in STEM Education
Lixiong Li, Ismaël Mourifié
Counterfactual analysis is central to education market design and provides a foundation for credible policy recommendations. We develop a novel methodology for counterfactual analy…
Production Function Estimation without Invertibility: Imperfectly Competitive Environments and Demand Shocks
Ulrich Doraszelski, Lixiong Li
We advance the proxy variable approach to production function estimation. We show that the invertibility assumption at its heart is testable. We characterize what goes wrong if inv…
