The Core of a Finite Exchange Economy: A Direct Proof of its Nonemptiness

Nomia, O. - Centre de recherche de mathématiques et économie … - 1997

The core of an economy consists of those states of the economy which no group of agents (coalition) can "improve upon". A coalition can improve upon a state of the economy if, by using the means available to that group, each member can be made better off. This paper presents the notion of the...

Preference Aggregation Functions and Arrows Theorem

Nomia, O. - Centre de recherche de mathématiques et économie … - 1997

The aim of this paper is to present Arrow's theorem and more generally the common framework of many results which can be called "Arrovian theorems". One begins by recalling the Condorcet majority rules, and why they fail: the "effet Condorcet". These rules are examples of preference aggregation...

Minimax Measures of Risk : Properties and Applications.

Bernis, G. - Centre de recherche de mathématiques et économie … - 2000

This paper adapts the methods of Minimax-Hedging developped in Bernis & Giraud [2000] to other models of financial markets, including discontinuous semi-martingale. The measure of the risk is defined as the value of a zero-sum game between the investor and a fictitious player, representing the...
