Payoff-dependent balancedness and cores (revised version)

Bonnisseau, Jean-Marc; Iehlé, Vincent - Departament d'Economia i Història Econòmica, … - 2007

We prove the non-emptiness of the core of an NTU game satisfying a condition of payoff-dependent balancedness, based on … transfer rate mappings. We also define a new equilibrium condition on transfer rates and we prove the existence of core payoff … vectors satisfying this condition. The additional requirement of transfer rate equilibrium refines the core concept and allows …

Overlapping Generations Economies and Symmetrical Economies under Extrinsic Uncertainty

Davila, J. - Departament d'Economia i Història Econòmica, … - 1998

The stationary structure of the simple overlapping generations economies is used to try to extend to the case with extrinsic uncertainty the characterizations of their stationary equilibria by means of symmetrical multiple equilibria of a related exchange economy in which the representative...

General Equilibrium with Asymmetric Information: a Dual Approach

Bel? Jerez - Departament d'Economia i Història Econòmica, … - 2000

We study markets where the characteristics or decisions of certain agents are relevant but not known to their trading partners. Assuming exclusive transactions, the environment is described as a continuum economy with indivisible commodities. We characterize incentive efficient allocations as...

Nash Implementation in Truthful Strategies, Strategy-Proofness and Efficiency on the Restricted Domain of Leontief Preferences

Nicolo, A. - Departament d'Economia i Història Econòmica, … - 1998

In exchange economies where agents have private information, strategy-proof social choice functions defined on large domains of preferences, are not efficient. We provide a restricted domain of preferences, namely the set of generalized Leontief utility functions, where there exist mechanisms...

Strategy-proof social choice

Barberà, Salvador - Departament d'Economia i Història Econòmica, … - 2010

This paper surveys the literature on strategy-proofness from a historical perspective. While I discuss the connections with other works on incentives in mechanism design, the main emphasis is on social choice models. This article has been prepared for the Handbook of Social Choice and Welfare,...

Implementation of the Walrasian Correspondence by Market Games

Carmen Bevi?Author-Email: Carmen.Bevia@uab.es; Luis C. … - Departament d'Economia i Història Econòmica, …

In this paper we present a set of axioms guaranteeing that, in exchange economies with or without indivisible goods, the set of Nash, Strong and active Walrasian Equilibria all coincide in the framework of market games.

Forming Efficient Networks

Pérez-Castrillo, David; Wettstein, David - Departament d'Economia i Història Econòmica, … - 2004

In this paper, we suggest a simple sequential mechanism whose subgame perfect equilibria give rise to efficient networks. Moreover, the payoffs received by the agents coincide with their Shapley value in an appropriately defined cooperative game.

Bidding for the Surplus: Realizing Efficient Outcomes in General Economic Environments

Mutuswami, Suresh; Pérez-Castrillo, David; Wettstein, David - Departament d'Economia i Història Econòmica, … - 2001

In this paper, we consider two classes of economic environments. In the first type, agents are faced with the task of providing local public goods that will benefit some or all of them. In the second type, economic activity takes place via formation of links. Agents need both to both form a...

Free Triples, Large Indifference Classes and the Majority Rule

Salvador Barber?Author-Email: salvador.barbera@uab.es; … - Departament d'Economia i Història Econòmica, … - 2002

We present a new domain of preferences under which the majority relation is always quasi-transitive and thus Condorcet winners always exist. We model situations where a set of individuals must choose one individual in the group. Agents are connected through some relationship that can be...
