In the paper we study some properties of competitive equilibria in the market model of Gale-Shapley type. We introduce a formal definition of equilibrium in this model without assumption about zero pricing of unassigned goods. We also prove that competitive equilibrium allocations in this model are strongly stable matchings in the Gale-Shapley sense (and vice versa).

W artykule zbadano pewne własności równowagi konkurencyjnej w modelu rynku typu Gale’a-Shapleya. Podano formalną definicję równowagi, w tym modelu bez założenia o zerowaniu się cen dóbr nieprzydzielonych. Udowodniono też, że alokacje równowagi konkurencyjnej w tym modelu są skojarzeniami silnie stabilnymi w sensie Gale’a-Shapleya (i na odwrót).
