I study how firms collect and use data and its implication on prices, competition, and welfare. My research focuses on real-world industries with imperfect competition and information or incentive problems, such as insurance and e-commerce.
I often work with large datasets from independent collaborations with firms. In my research, I develop formal analytical models that allow me to quantify complex but empirically important features of consumer demand and firm conduct.
