The objective of this study is to analyze the macroeconomic performance of 16 Ibero- American countries over the period 1980- 199 1. Macroeconomic performance is defined as the ability of a country's macroeconomic managers to provide four welfare-enhancing economic services to their citizens: a...

Suppose that a group of individuals owns collectively a technology which produces a consumptiongood by means of a (possibly heterogeneous) input. A sharing rule associates input contributionswith a vector of consumptions that are technologically feasible. We show that the set of...

We characterize the incentive compatible allocation that maximizes the expected social surplus in a single-unit sale when the efficient allocation is not implementable. This allocation may involve no selling when it is efficient to sell. We then show that the English auction always implements...

This paper develops a two-sector model for a renewable natural resource based economy. Pareto efficient results show the optimal harvesting rate that allows for sustained long-run optimal growth, which is upper-bounded by the biological rate of reproduction. Regulation prevents from resource...

Let µ be a rational distribution over a finite alphabet, and ( ) be a n-periodic sequences which first n elements are drawn i.i.d. according to µ. We consider automata of bounded size that input and output at stage t. We prove the existence of a constant C such that, whenever , with...

This paper examines the stability of deterministic steady-states in a class of economies where the state -variable is one dimensional and where agents use Bayesian techniques to form expectations. Thr dynamics with learning are locally convergent if the prior mean is close to a stable perfect...

This paper analyzes the possibility of irnplementing stable outcomes for marriage markets. Our first result shows a contradiction between the use of stable mechanisins and the hypotesis of agents' behaviour consiclered in the Nash equilibriurn concept . We analyze the possibility of...

This paper presents a model of network formation with costly links. We endogenize the amount of cost born by each player involved in a bilateral link by considering that these shares result from bargaining. We analyze this feature in a context of coordination games. We show that, if the cost of...

This paper considers market economies involving the choice of a public environment when there are nonconvexities in production. It discusses the decentralization of efficient allocations by means of valuation equilibrium, adapting to many private goods the notion due to Mas-Colell (1980) which...

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.
