EQUILIBRIUM AND OPTIMALITY IN MODELS OF INTERREGIONAL TRADE IN MONOPOLISTIC COMPETITION: A UNIFIED APPROACH
https://doi.org/10.32324/2412-8945-2022-3-21-29
Abstract
The models of interregional trade under monopolistic competition of producers are studied. The situations of market equilibrium and social optimality are considered. it is shown: (1) in a situation of symmetrical market equilibrium, the elasticities of production costs are a convex combination of elasticities of revenue from individual consumption; (2) in a situation of symmetrical social optimality, the elasticities of production costs are a convex combination of elasticities of elementary utilities from individual consumption.

Supporting agencies: the study was carried out within the framework of an internal grant from the Siberian Institute of Management RANEPA April — June 2022. The authors consider it their pleasant duty to express sincere gratitude to their colleagues at the Scientific and Educational Center “Digital Transformation of the Economy” and especially at the Department of Business Statistics and Analytics Siberian Institute of Management RANEPA for useful discussions.
