My research interests cover topics in both industrial organization and international trade, with an emphasis on measurement of productivity, research and development (R&D), innovation, and the interaction between firm heterogeneity and firm activities. I emphasize firm heterogeneity in productivity, technology usage, and demand shocks when analyzing firm activities such as participation in importing/exporting, R&D, entry/exit decisions, and investment decisions.
