Jung Ho Choi investigates how informational frictions and innovations have an influence on the processes and outcomes of the labor market and how these factors interact with each other. Using corporate disclosure as a major research setting, he studies how informational frictions, especially about employers, can interact with the labor market in three different dimensions: 1) Corporate disclosure (e.g., accounting fraud) has an impact on corporate decisions, which, in turn, affect the labor market (e.g., wage and job turnover); 2) Corporate disclosure shapes the labor market as employees, as an important stakeholder, consumes corporate disclosure (e.g., earnings announcements) for decision making (e.g., job search); 3) Employees, as an input in the (information) production function, have an impact on corporate disclosure. Additionally, he studies how corporate disclosure (e.g., cost structure disclosure) has an impact on individual and aggregate productivity and innovation (e.g., cost innovation and productivity dispersion).
