About the Lab
Professor Joung Yeob Ha's research lab specializes in empirical macroeconomics and economic history, with a focus on addressing measurement error and bias in historical data using innovative econometric methods. The lab develops advanced statistical techniques—such as set identification, sample restriction, and parametric bias correction—to improve the reliability of regression analyses in settings with non-classical measurement error, particularly using digitized historical sources like newspapers. A key research direction involves analyzing the long-term effects of institutional and policy changes, such as legal access to alcohol, on social and educational outcomes. The lab emphasizes methodological rigor and replication of existing findings to ensure robustness and transparency in empirical economics.

5This paper shows how to remove attenuation bias in regression analyses due to measurement error in historical data for a given variable of interest by using a secondary measure that can be easily generated from digitized newspapers. We provide three methods for using this secondary variable to deal with non-classical measurement error in a binary treatment: set identification, bias reduction via sample restriction, and a parametric bias correction. We demonstrate the usefulness of our methods by
This paper estimates the effect of legal access to alcohol on academic performance.I find that legal access to alcohol has a negative effect on academic performance, but the magnitude is smaller than previously documented.Exploiting the richness of an administrative data set that links academic performance to student activities, I test for heterogeneous impacts across dimensions not previously studied.Notably I find there is no significant effect of legal access for fraternity and sorority membe
