Walrasian Economics

This book is a comprehensive study of Leon Walras's influence in economics.

This book explains the state of Walrasian general economic equilibrium theory and its history, which incorporates most of microeconomic theory. The treatment examines the foundations of the legacy of Léon Walras, the originator of general equilibrium theory, and his influence as manifested in the work of his successors.In order to understand the various strands of general equilibrium theory, why it has taken the forms that it has since the time of Léon Walras, and to appreciate fully a view of the state of general equilibrium theorising, it is essential to understand Walras's work and examine its influence. The first section of this book accordingly examines the foundations of Walras's work. These include his philosophical and methodological approach to economic modelling, his views on human nature, and the basic components of his general equilibrium models. The second section examines how the influence of his ideas has been manifested in the theorising of his successors, surveying the models of theorists such as H. L. Moore, Vilfredo Pareto, Knut Wicksell, Gustav Cassel, Abraham Wald, John von Neumann, J. R. Hicks, Kenneth Arrow, and Gerard Debreu. The treatment also examines models of many types in which Walras's influence is explicitly acknowledged.
