Oliva, Marina Nunez; Pallarola, Carlos Rafels - Facultat d'Economia i Empresa, Universitat de Barcelona - 2005

Uniform{price assignment games are introduced as those assignment mar- kets with the core reduced to a segment. In these games, for all active agents, competitive prices are uniform although products may be non-homogeneous. A characterization in terms of the assignment matrix is given. The only...

Bargained stable allocations in assignment markets

Núñez, Marina; Rafels, Carles - Barcelona Graduate School of Economics (Barcelona GSE) - 2004

For each assignment market, an associated bargaining problem is defined and some bargaining solutions to this problem are analyzed. For a particular choice of the disagreement point, the Nash solution and the Kalai-Smorodinsky solution coincide and give the midpoint between the buyers-optimal...

Single-valued solutions for the Bohm-Bawerk horse market game

Oliva, Marina Nunez; Pallarola, Carlos Rafels - Facultat d'Economia i Empresa, Universitat de Barcelona - 2003

Singlevalued solutions for the case of twosided market games without product differentiation, also known as B ohmBawerk horse market games, are analyzed. The nucleolus is proved to coincide with the value, and is thus the midpoint of the core. Moreover a characterization of this set of games in...

The assignment game: core bounds for mixe-pair coalitions

Oliva, Marina Nunez; Pallarola, Carlos Rafels - Facultat d'Economia i Empresa, Universitat de Barcelona - 2002

In the assignment game framework, we try to identify those assignment matrices in which no entry can be increased … mixedpair coalition attains the corresponding matrix entry in the core of the game. For a given assignment game, a unique … buyerseller exact assignment game with the same core is proved to exist. In order to identify this matrix and to provide a …
