Two extensions of preferences over individuals to preferences over sets are suggested. For the first one, derived from the most prefered member of a set, it is shown that a stable partition always existis if the original preferences are strict and a simple algorithm for its computation is derived. This algorithm turns out to be strategy proof. The second extension, based on the least prefered member of a set, produces solutions very similar to those for the stable roornmates problem.application/pdfengAtribución-NoComercial-SinDerivadas 3.0 EspañaMatching marketsStable partitionDigraphsAlgorithmsworking paperEconomíaopen access
