Исследуются модели межрегиональной торговли при монополистической конкуренции производителей. Рассматриваются ситуации рыночного равновесия и общественной оптимальности. Показано: (1) в ситуации симметричного рыночного равновесия эластичности производственных издержек являются выпуклой комбинацией эластичностей выручки от индивидуальных потреблений; (2) в ситуации симметричной общественной оптимальности эластичности производственных издержек являются выпуклой комбинацией эластичностей элементарных полезностей от индивидуальных потреблений.

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.
