These orderings provide potential criteria for determining the suitability of agents to be assigned to an object. A candidate for a definable equilibrium is an assignment of the agents to the objects and an attachment of a single criterion to each object. In equilibrium, each agent is better-suited to his assigned object than any agent who envies him, according to the criterion attached to that object. We analyze the equilibrium notion and provide some examples.EnglishDefinabilityDefinable equilibriumObject assignment modelArticle10.1007/s10058-021-00267-21434-4750
