Almost-dominant Strategy Implementation
Schummer, James - 1999
Though some economic environments provide allocation rules that are implementable in dominant strategies (strategy-proof), a significant number of environments yield impossibility results. On the other hand, while there are quite general possibility results regarding implementation in Nash or...

Liberal egalitarianism and the harm principle
Lombardi, Michele; Veneziani, Roberto - 2009
This paper analyses Rawls's celebrated difference principle, and its lexicographic extension, in societies with a finite and an infinite number of agents. A unified framework of analysis is set up, which allows one to characterise Rawlsian egalitarian principles by means of a weaker version of a...

On the leximin and utilitarian overtaking criteria with extended anonymity
Kamaga, Kohei; Kojima, Takashi - Center for Intergenerational Studies, Institute of … - 2008
This paper studies the extensions of the infinte-horizon variants of the leximin principle and utilitarianism on the …-continuity (or Consistency) and the extended anonymity axiom called Q-Anonymity. We formulate new extended leximin and utilitarian … social welfare relations (SWRs), called Q-W-leximin SWR and Q-overtaking criterion respectively, and show that Weak …

Trees and Decisions
Alós-Ferrer, Carlos; Ritzberger, Klaus - Department of Economics and Finance Research and … - 2003
The traditional model of sequential decision making, for instance, in extensive form games, is a tree. Most texts de?ne a tree as a connected directed graph without loops and a distinguished node, called the root. But an abstract graph is not a domain for decision theory. Decision theory...

Resource-Monotonicity for House Allocation Problems
Ehlers, Lars; Klaus, Bettina - Departament d'Economia i Història Econòmica, … - 2003
We study a simple model of assigning indivisible objects (e.g., houses, jobs, offices, etc.) to agents. Each agent receives at most one object and monetary compensations are not possible. We completely describe all rules satisfying efficiency and resource-monotonicity. The characterized rules...

Leadership in Collective Action
Esteban, Joan; Hauk, Esther - Departament d'Economia i Història Econòmica, … - 2008
We extend the model of collective action in which groups compete for a budged by endogenizing the group platform, namely the specific mixture of public/private good and the distribution of the private good to group members which can be uniform or performance-based. While the group-optimal...

ARROW’S IMPOSSIBILITY THEOREM: PREFERENCE DIVERSITY IN A SINGLE-PROFILE WORLD
Serrano, Roberto; Feldman, Allan M. - Centro de Estudios Monetarios y Financieros (CEMFI) - 2007
In this paper we provide a simple new version of Arrow’s impossibility theorem, in a world with only one preference profile. This theorem relies on a new assumption of preference diversity, and we explore alternative notions of preference diversity at length.
