About the Lab
Professor Ji Hoon Cho's research lab specializes in industrial organization and information economics, with a focus on how public policy and institutional enforcement affect market transparency, information disclosure, and market efficiency. The lab investigates the impact of regulatory interventions—particularly in asymmetric information markets such as the used car market—on pricing behavior, liquidity, and information reliability. Current research explores how mandatory disclosure rules and law enforcement enhance market outcomes by improving information credibility and participant trust. The lab combines empirical industrial organization with field experiments and natural experiments to analyze real-world market dynamics.

2We study the used car market to understand how public enforcement that intends to increase information reliability affects disclosure, pricing, and liquidity. In 1986, federal rules mandated the creation of odometer records, and states enforced the law in a staggered fashion. We find that used car asking-price sensitivity to mileage increases by 32.6%, and mileage disclosure in classified ads increases by 23.4%. The findings suggest that strengthened law enforcement increases odometer credibilit
