Prices, Reproduction, Scarcity

Christian Bidard revives the accents of classical theory to look at the theory of long-run competitive prices. This exhaustive book is the 2004 version of Prix, Reproduction, Rareté (Dunod, 1991) and aims to provide an essential reference on this topic.

Originally published as a French edition in 1991, and first translated into English for this Cambridge edition in 2004, in this exhaustive study Christian Bidard develops a theory of prices of production. This theory breaks down the symmetry between producers and consumers and gives more importance to reproduction rather than scarcity. In his analysis of multiple-product systems, Bidard focuses on the notion of an all-engaging system which elucidates the link with von Neumann's theory; examines the notions of sector and vertical integration which make possible an elegant treatment of fixed capital; clarifies the status of the internal rate of return; proposes a general theory of rent. In the discussion of capital theory and marginal equalities or, more specifically, the treatment of exhaustible resources, Bidard compares different readings of Sraffa's work and revisits the question of relationships between classical theory (Smith, Ricardo, Marx) and the general equilibrium theory (Walras, Arrow, Debreu).
