Industrial Economics (ECON30003)

This subject is an introduction to the field of industrial organisation. Industrial organisation deals with the structure, management, and performance of firms and markets. It is concerned with firm behaviour and strategy, the implications of firm behaviour for economic efficiency, and the role public policy plays in promoting efficiency. Most of the time, models of perfect competition and monopoly fail to explain the composition and behaviour of most industries in modern capitalist economies. Our goal in this class is to depart from those two idealised models and to explain why industries are composed of a few large firms instead of many small ones. We will be looking at the strategic interactions between firms in a market, and analysing such market phenomena as price discrimination, product differentiation, price wars, mergers, vertical relationships between firms, advertising, entry and exit, and research and development. Whenever possible, we will try to study real-world applications of the theories that we learn in class.
