Linear multisectoral models have been applied to development planning in countries with different socioeconomic systems. The relative simplicity of the underlying technique has concealed much of the conceptual differences between modelling in East and West. However, the recent development of more sophisticated models, under the general title of computable general equilibrium models, has apparently enhanced these differences, and concealed the possibility that these models could also be used in both East and West. This paper investigates issues related to the possible adaptation of equilibrium modelling techniques for central planning purposes.
