Walrasian economics

by Donald A. Walker

In order to understand the various strands of general equilibrium theory, why it has taken the forms that it has since the time of Leon Walras, and to appreciate fully a view of the present state of general equilibrium theorizing, it is essential to understand Walras's work and examine its influence. The first section of the book accordingly examines the foundations of Walras's work. These include his philosophical and methodological approach to economic modeling, 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 theorizing 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 recent models of many types in which Walras's influence is explicitly acknowledged.
