Research Interests of Ginger Z. Jin (as of September 25, 2018) Most of my research focuses on empirical studies in information economics, especially how market mechanisms alleviate information asymmetry among economic agents and what role government regulations play in information markets. The most common applications are in food safety, health care, online markets, environmental issues, development, and intrafamilial interactions.
