In this paper we develop a differentiable approach to deal with incentives in a, possibly small, subset of a general domain of preferences in economies with one public and one private good. We show that, for two agents, there is no social rule which is efficient, nondictatorial and...

Many policies simultaneously affect the distribution of prices and incomes in the economy. Moreover, a bias may occur when there is a stochastic relationship between prices and incomes and this relationship is being ignored. It is therefore important to dispose of an analytical framework for...

This paper studies a class of NTU coalition formation games in which every player's payoff depends only on the members of her coalition. We identify four natural conditions on individuals' preferences and show that, under each condition, stable (core) allocations exists.

There is a recent tendency toward encouraging universities to merge. This policy is based on the idea that mergers create synergy gains that enhance universities’ prestige by increasing their international visibility. However, this process may reduce competition for both research funds and...

This paper studies convergence and stability properties of Sjöström's (1994) mechanism, under the assumption that boundedly rational players find their way to equilibrium using monotonic learning dynamics and best-reply dynamics. This mechanism implements most social choice functions in...

We study the dynamic implementation of the first-best for King Solomon's Dilemma, on the assumption that boundedly rational players find their way to equilibrium using monotonic evolutionary dynamics, and also with best-reply dynamics. We find that, although the mechanisms proposed by the...

The stationary sunspot equilibria of a simple OLG economy with heterogeneous agents areconsidered. These equilibria are known to be suboptimal. The focus of the paper is on the efficacy,based on welfare economic considerations and informational requirements, of government policy insuch an...

We consider allocation problems with indivisible goods when agents’ preferences are single-peaked. Two natural procedures (up methods and temporary satisfaction methods) are proposed to solve these problems. They are constructed by using priority methods on the cartesian product of agents and...

We consider general OLG economies under uncertainty, with dividend paying assets of infinite maturity and money, and in which one good is available for consumption. We study the optimality properties of equilibria when asset markets are allowed to be sequentially incomplete. We show that if...

We consider pure exchange, one good OLG economies under stationary Markov uncertainty. It is known that when markets are sequentially complete, a stationary equilibrium at which the agents common matrix of intertemporal rates of substitution has a Perron root which is less than or equal to one...
