The Economic Theory of Product Differentiation
John Beath, Yannis KatsoulacosISBN: 0521335523; 9780521335522;
This book presents economic theories that seek to explain the prevalence of differentiated products in market economies. It uses these theories to derive market equilibria and to compare these to social optima for both horizontally and vertically differentiated products. The implications of product differentiation for market structure and power, strategic entry deterrence and international trade are all examined.
