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...

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...

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...

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 reports an experimental investigation on two mechanisms for the so-called King Solomon Dilemma, where one of them fails to implement the social choice rule dynamically. We compare the two mechanisms in terms of their welfare, incentive and learning properties.

This paper introduces &tao;-fairness as a compromise solution reconciling Pareto efficiency and equity in School Choice Problems. We show that, by considering a weak notion of equity that we refer to as ¿-equity, it is possible to contribute positively to solve an open debate, originated by the...

The matching of individuals in teams is a key element in the functioning of an economy. The network of social ties can potentially transmit important information on abilities and reputations and also help mitigate matching frictions by facilitating interactions among ¿screened¿ individuals. We...

The form of the Engel curve has long been a subject of discussion in appliedeconometrics and until now there has no been definitive conclusion about its form. In this paperan additive partially linear model is used to estimate semiparametrically the effect of totalexpenditure in the context of...
