My research is focused on applying microeconomic theory and econometrics to the analysis of issues concerning firm behavior and market operation.  Here are the research areas I currently feel most interested in:

· Markets with asymmetric information

· Product differentiation: price and non-price competition

· Entry/exit behavior, market structure

· Estimation of structural models

· Discrete choice models

In my Ph.D. dissertation Incentives, Effectiveness and Welfare Impact of Quality Information Supply, I study how and to what extent market-driven and government-enforced information provision on product quality alleviates informational problems that consumers may face.
