Lesley Chiou's research is in the areas of Industrial Organization and Applied Econometrics. Her recent work focuses on consumer behavior and firm strategy on the internet.


Professor Chiou's primary fields of interest are Industrial Organization and Applied Econometrics. Industrial Organization explores the consequences of firm strategy and government competition policy. Applied Econometrics uses data and statistical tools to test predictions of economic theory or to evaluate outcomes of government policies.

Professor Chiou's current research focuses on consumer search and firm strategy on the internet. Her recent work examines how consumers respond to online advertising and copyright on search engines and social media sites. Her prior work also studies how online and offline firms compete; how consumers respond to pricing changes in retail markets; and how demand evolves for arts and media markets.
