Jean Gabszewicz's new book is devoted to the study of strategic multilateral exchange. Contrary to the classical competitive paradigm in which agents are assumed to behave as price takers, here traders are allowed to consciously behave as strategic agents who aim to influence trade to their own advantage. This is usually done in oligopoly theory using a partial equilibrium approach while in this case a system of interrelated markets is considered. Primarily, the book discusses the game-theoretic concept of core and the relationship between core and the set of price allocations in economies embodying significant traders is explored. The author goes on to adopt a non-cooperative approach building on the concept of Nash equilibrium. Strategic Multilateral Exchange will be welcomed by academics, advanced research scholars and doctoral students with an interest in economic theory, microeconomic theory and general equilibrium. It will also appeal to mathematical economists with an orientation in mathematical economics and game theory.

Microeconomic Theories of Imperfect Competition: Old Problems and New Perspectives is an authoritative collection of readings which, together with a new, original introductory essay by the editors, provides a broad overview of the major theoretical concepts in the field.This collection includes published papers on industry size: quantity and price competition, entry barriers, product differentiation, incomplete information, general equilibrium with imperfect competition. This book will be essential reading both for those seeking an introduction to the subject and those seeking a new perspective.

Strategic Interaction and Markets explores the theoretical richness of economic contexts such as product differentiation, strategic barriers to entry, and imperfect information, where economic agents act strategically taking into account the impact of their behaviour on competitors' behaviour and prices. This non-ideal form of competition is the standard result when competition is amongst a small number of agents. Designed as an ancillary text for graduate students, this book is an accessible introduction to the applications of a complex area of mathematical economics.
