%0 Report %A Camiña Centeno, Ester %T Some results on stability concepts for matching models %J Documentos de trabajo del Instituto Complutense de Análisis Económico (ICAE) %D 2010 %U https://hdl.handle.net/20.500.14352/48956 %X We consider a general class of two-sided matching markets, called many-to-one matching markets with money. For a special case of these markets, where each seller owns di¤erent objects, we prove that stable outcomes cannot be characterized by the non-existence of unsatis…ed pairs. Moreover, we restore the dual lattice structure in markets with more than one seller using a connection with an assignment game. %~
