In this paper we analyze the explicit representation of fixed agenda social choice correspondences under different rationality assumptions (independence, neutrality, monotonicity,...).It is well known in the literature that, under some of these assumptions, the existence of dictators,...

We model the trading possibilities of one seller and n potential buyers as a strategic game, which extends the two-person sealed-bid double auction. We introduce particular communication equilibria for this game, the self-fulfilling equilibria. In the case of arbitrary informational...

We extend the theory of constrained egalitarianism initiated by Dutta and Ray (1989) with a view of making it more widely applicable to normative and public economics. The paper is concerned with redistributive systems in which what the individuals get depends on what they receive or pay qua...

We focus on the concept of impulse in econometrics analysis of time series. We recognize two useful characterizations, which are respectively deterministic and stochastic.

It is well known that, whereas in one-agent contexts the value of information is always positive, in strategic situations, this is not always the case. We will consider the class of games for which, under a specific information structure, there exists a unique Pareto payoff profile, and we show...

Ce papier montre, au travers de l'exemple du Groupe Danone, la necessaire coherence entre politique financiere et strategie de la firme. Apres un virage strategique majeur, le groupe, en depit d'une image negative, a du convaincre les marches de capitaux de financer sa croissance externe et la...

This paper considers the relative efficiency of ad valorem and unit selective sales taxes in imperfectly competitive market. We provide a simple proof of the proposition that ad valorem taxes are welfare-superior to unit taxes in the short run whenproduction costs are identical across firms.

A social choice correspondence called the Essential Set is studied with the help of an axiom called Cloning Consistency.

This paper examines some consequences of the assumption that individuals constrain morally their behaviour in games in general and in games of voluntary provision of public good in particular. Moral behaviour is defined in terms of a maxim which assigns one moral action to every player. Maxims...
