INDUSTRIAL ORGANIZATION II

ECO 2901: Winter 2019

COURSE DESCRIPTION

This course deals with Empirical Industrial Organization. It covers topics related to econometric models and empirical applications of competition in industries. We study empirically the determinants of firms’ behaviour and market outcomes in the context of problems of price and quantity competition, investment, innovation, product design, networks, or market entry/exit. The course focuses on research papers using empirical games to investigate firms’ strategies and competition, and how firms’ information and beliefs play a fundamental role in the nature of competition and on market outcomes and welfare. The covered topics include recent research that relax standard assumptions of firms’ rational expectations and allow for firms’ limited information, biased beliefs, and learning. The course emphasizes the importance of combining data, economic models, and appropriate identification strategies and econometric techniques to answer empirical questions in economics.
