Реферат:
The fuzzy core is well-known in theoretical economics, it is widely applied to model the conditions of perfect competition. In contrast, the original author’s concept of fuzzy contractual allocation as a specific element of the fuzzy core is not so widely known in the literature, but it also represents a (refined) model of perfect competition. This motivates the study of its validity: the existence of fuzzily contractual allocations in an economic model; it also implies the existence (non-emptiness) of the fuzzy core and develops an approach from [15]. The proof is based on two well-known theorems: Michael’s theorem on the existence of a continuous selector for a point-to-set mapping and Brouwer’s fixed point theorem. In literature, only the non-emptiness of the fuzzy core was proven under essentially stronger assumptions— typically, it applies replicated economies and Edgeworth equilibria.
