A price uncertainty principle and the existence of sequential equilibrium : (I) A numerical example

Boisdeffre, Lionel De - HAL - 2010

In three related papers, we consider a pure exchange financial economy, where agents may observe private information signals, form private anticipations and face an "exogenous uncertainty", on the future state, and an "endogenous uncertainty", on the future prices. At a sequential equilibrium,...

Arbitrage and price revelation with private beliefs

Boisdeffre, Lionel De - HAL - 2012

We extend the Cornet-de Boisdeffre (2002-2009) asymmetric information finite dimensional model to a more general setting, where agents may forecast prices with some private uncertainty. This new model drops both Radner's (1972-1979) classical, but restrictive, assumptions of rational...

On the existence of financial equilibrium when beliefs are private

Boisdeffre, Lionel De - HAL - 2012

We consider a pure exchange financial economy, where agents, possibly asymetrically informed, face an "exogenous uncertainty", on the future state of nature, and an "endogenous uncertainty", on the future price in each random state. Namely, every agent forms private price anticipations on every...

Price revelation and existence of equilibrium in a private belief economy

Boisdeffre, Lionel De - HAL - 2013

We consider a pure exchange financial economy, where rational agents, possibly asymmetrically informed, forecast prices privately and, therefore, face "exogenous uncertainty", on the future state of nature, and "endogenous uncertainty" on future prices. At a sequential equilibrium, all agents...

Contre les territoires jetables. Première approche critique des systèmes d'identification des territoires.

Gwiazdzinski, Luc - HAL - 2013

"Vertige" est le mot qui vient immédiatement à l'esprit quand nous contemplons le tourbillon des logos et marques territoriales qui s'étalent désormais sous nos yeux. " Inquiétude " c'est le sentiment que l'on peut ressentir à la vue des bricolages visuels et des simplifications qui...

Competing with Equivocal Information

Perez-Richet, Eduardo - HAL - 2012

This paper studies strategic disclosure by multiple senders competing for prizes awarded by a single receiver. They decide whether to disclose a piece of information that is both verifiable and equivocal (it can inuence the receiver both ways). The standard unrav- eling argument breaks down: if...
