Jinyong Hahn

Jinyong Hahn is a Professor of Economics at the University of California, Los Angeles (UCLA). He holds a Ph.D. from Harvard University and has held previous appointments at the Universities of Pennsylvania, Michigan, and Brown. His primary research focuses on theoretical econometrics, particularly developing methodologies for analyzing micro-econometric data. He specializes in panel data models, information characterization in econometric models, and bias correction techniques.

Professor Hahn has served as Co-Editor of Econometric Theory and Associate Editor of Econometrica and the Journal of Econometrics. His work emphasizes rigorous statistical methods for causal inference, instrumental variable estimation, and model validation. Recent research explores topics such as treatment effects estimation, overidentification in shift-share designs, and the public health implications of vaccination policies.

His contributions span advanced econometric theory, including central limit theorems for combined cross-sectional and time-series data, quantile regression with panel data, and nonparametric identification techniques. He has also addressed challenges in dynamic nonlinear panel models and bias reduction strategies for discrete choice models.

While no specific grants or awards are explicitly listed, his editorial roles and prolific publication record highlight his influence in the field. His research consistently bridges theoretical advancements with applied econometric challenges in policy evaluation and social science analysis.
