Questioning about game theory as an institutionalism theory could seem unsound at first glance. In game theory, the very basic concept of players’ strategies is quite individualistic and really independent on any social constraint and other institutional consideration. On another hand, the...

Toward the late 1990s, several research groups independently began developing new, related theories in mathematical finance. These theories did away with the standard stochastic geometric diffusion "Samuelson" market model (also known as the Black-Scholes model because it is used in that most...

The set of all Bayesian–Nash equilibrium payoffs that the players can achieve by making conditional commitments at the interim stage of a Bayesian game coincides with the set of all feasible, incentive compatible and interim individually rational payoffs of the Bayesian game. Furthermore, the...

This paper examines a decentralized, dynamical, pure exchange economy in which changes in an individual consumers demand depend on his own consumption and on prices. An ‘instantaneous Walras law’ provides a sufficient condition for the existence of viable exchange trajectories. Such dynamic...

The aim of the paper is to analyze the impact of heterogeneous beliefs in an otherwise standard competitive complete markets discrete time economy. The construction of a consensus belief, as well as a consensus consumer are shown to be valid modulo a predictable aggregation bias, which takes the...

The competitive equilibrium correspondence, which associates equilibrium prices of commodities and assets with allocations of endowments, identifies the preferences and beliefs of individuals under uncertainty; this is the case even if the asset market is incomplete.

This article proposes a theory of banking of emission permits under conditions of regulatory uncertainty. Based on a two-period partial equilibrium framework, we examine the effects of increasing risk - in the sense of a mean-preserving spread - regarding a future permits allocation at the...

This paper examines seasoned equity offerings in France. Even though a rights offering is the primary flotation method, French companies are increasingly using the relatively expensive public offering method. We show that the market reaction to the announcement of seasoned equity issues is...

In this article, we investigate the relevance of the glass ceiling hypothesis in France, according to which there exist larger gender wage gaps at the upper tail of the wage distribution. Using a matched worker-firm data set of about 1 30 000 employees and 14 000 employers, we estimate quantile...
