This paper reviews the present state of the debate on linear joint production models and discusses its relevance. The primary interest of the investigation of the difficulties inherent in joint production appears to be that it contributed to the re-establishment of a number of basic economic notions. The distinction between individual and market values was substituted for the traditional conception. A new, and more appropriate, condition for the existence of values (the nonreductivity of the technology) has been proposed. The consideration of a general classical equilibrium replaced the treatment of prices and outputs in separate frameworks. The discussion of the framework in which the condition for the existence of this equilibrium should be formulated stressed the importance of the consideration of disequilibrium phenomena in a classical perspective. However, much work remains to be done with respect to both equilibrium and disequilibrium analyses.
