Definition 2. A matching μ is stable if it is individually rational and if it is not blocked by any pair of agents (X, x)∈ F × M. We denote the set of stable matchings μ for a given marriage problem (F, M, ≻) by S. Gale and Shapley (1962) show that for any problem (F, M, ≻), a stable matching exists.

WebThe theory of stable matchings has become an important subﬁeld within game theory, as documented by the bookofRoth and Sotomayor (1990). Game theorists are interested in the applications of matching theory in real markets. However, the theory of stable matchings also appeal to combinatorialists and computer scientists. Indeed, the ﬁrst WebThe set of envy-free matchings turns out to be a lattice, and the set of stable matchings equals the set of fixed points of a Tarski operator on this lattice. Informally speaking, envy-freeness is a relaxation of stability that allows blocking pairs involving a doctor and an empty position of a hospital. ipcw method

These solution concepts are all core consistent.

Webmatchings that maximize social surplus are stable.
