This paper sheds a new light on the puzzling negative relationship between nominal stock returns and expected inflation. The assertion that stocks offer a hedge against inflation is theoretically founded on the Fisher identity. Contrary to this fundamental view, recent empirical tests reject...

Dans une économie de marchés financiers, soumis au risque de disfonctionnement, où les actifs financiers sont des substituts imparfaits, on ne peut pas négliger les marchés financiers et monétaires dans les décisions de politique monétaire comme le suppose actuellement la littérature de...

The recent rise of excess liquidity in the United States and in the euro zone did not result in a resurgence of inflation. Excess liquidity, rather than heading towards the market of consumer goods, could have moved towards the asset markets. In the data covering the period going from 1980 to...

Cet article fournit un point de vue opposé au consensus d’« une macroéconomie sans LM ». Elle montre que, lorsque la politique monétaire est spécifiée en termes de règle du taux d’intérêt et la banque centrale ne contrôle pas directement les taux d’intérêt affectant la demande...

We consider a dynamic version of sender-receiver games, where the sequence of states follows an irreducible Markov chain observed by the sender. Under mild assumptions, we provide a simple characterization of the limit set of equilibrium payoffs, as players become very patient. Under these...

We study the development of a duopoly industry -evolution of firm capacities and competitive behavior- in a continuous-time real-options model of capacity investment. Our methodology allows the evaluation of investment options and exercise rules in a strategic setup. In the initial industry...

We study a simple duopoly model of preemption with multiple investments and instantaneous Bertrand competition in a stochastically growing market. Different patterns of equilibria may arise, depending on the importance of the real option effect. If the average growth rate of the market is close...

This paper is concerned with the incentive properties of the Matthew Effect by which since Merton [1968] one is usually describing the various cumulative advantages that obviously affect academic competition. We introduce a model of sequential contests in which the agents that have initially...
