EXCHANGE, DEMAND AND THE MARKET-PRICE OF PRODUCTION: RECONCILING TRADITIONAL AND MONETARY APPROACHES TO VALUE AND PRICE

Abstract

This paper seeks to reconcile two very different views existing in the literature concerning how exchange and demand affect the magnitude of commodity values. Traditionally, value is considered to be created in production and subsequently realized in exchange. An alternative monetary approach posits that exchange itself contributes to the determination of commodity values. Proponents of each view claim that significant parts of Marx’s theory of value are compromised if their interpretation of the role of exchange is not adopted. Drawing on the work of Rosdolsky and Roberts, I argue that it is necessary to distinguish between the effects of exchange and demand. Exchange acts to reduce concrete, private labor to abstract social labor, while demand affects the magnitude of labor considered “socially necessary” in the sense of being expended in accordance with existing social need. I identify a new category of exchange value – the market-price of production – and use it to explain how changes in demand act to redistribute value across industries by affecting the magnitude of abstract labor considered to be socially necessary. In this way the major claim of the two approaches to exchange are reconciled. The magnitude of value is fully determined in production. At the same time monetary exchange effects, or brings about, a social division of labor by reducing concrete, private labor to abstract social labor and by distributing value according to social need as expressed by effective demand.
