On the existence of most-preferred alternatives in complete lattices

Kukushkin, Nikolai S. - Volkswirtschaftliche Fakultät, … - 2010

If a preference ordering on a complete lattice is quasisupermodular, or just satisfies a rather weak analog of the condition, then it admits a maximizer on every subcomplete sublattice if and only if it admits a maximizer on every subcomplete subchain

Ordinal Games

Durieu, Jacques; Haller, Hans; Querou, Nicolas; Solal, … - 2007

We study strategic games where players' preferences are weak orders which need not admit utility representations. First of all, we ex- tend Voorneveld's concept of best-response potential from cardinal to ordi- nal games and derive the analogue of his characterization result: An ordi- nal game...

Games with Complementarities

Filippo L., CALCIANO - Institut de Recherche Économique et Sociale (IRES), … - 2007

We introduce a class of games with complementarities that has the quasisupermodular games, hence the supermodular games, as a special case. Our games retain the main property of quasisupermodular games : the Nash set is a nonemply complete lattice. We use monotonicity properties on the best...
