Decisions on Production and the Behaviour of Savers in Recent General Equilibrium Models

Modern general equilibrium theory faces notorious difficulty in extending the analysis of production to economies without complete forward markets, since at the ‘initial date’ the owners of any firm will typically disagree about the choice of the production plan. This paper examines the main approaches to the problem, with the specific aim of verifying whether they allow a satisfactory account of the interplay between firms and savers. It is argued that the theory oscillates between assumptions that may prove incompatible with savers' rationality, and hypotheses that prevent this shortcoming but render the formation of production decisions quite hard to explain.
