Demand and Exchange in Economic Analysis provides a rare combination of detailed analysis of a central area of economics with the history of economic thought. The first part of the book examines major attempts to treat mathematically the partial equilibrium concept of demand conceived as a schedule. The second part, after generalizing Cournot's model of trade in a single good, traces the general equilibrium analysis of exchange. This adds to the concept of a demand curve the fundamental interpretation of the rate of exchange, or price ratio, in terms of the amount of one good offered in return for a unit of another good. The similarity in the treatments of Mill, Whewell, Marshall and Walras is revealed along with the emphasis on multiple equilibria. Edgeworth's grand synthesis and extension of Jevons's approach to exchange is then discussed in detail. The book will be of interest to a wide range of economists interested in placing modern theory in historical perspective.
