Purpose – In games with strategic complementarities, public information about the state of the world has a larger impact on equilibrium actions than private information of the same precision, because the former is more informative about the likely behavior of others. This may lead to...

We propose a speculative attack model in which agents receive multiple public signals. It is characterised by its focus on an informational structure, which sets free from the strict separation between public information and private information. Diverse pieces of public information can be taken...

In currency exchange markets, there is a conflict between individual decisions and the socially optimal solution. Whereas agents have a coordination motive to take the same position, at the social level effective market coordination per se is not socially valuable, and the central bank aims at...

Financial markets and macroeconomic environments are often characterized by positive externalities. In these environments, transparency may reduce expected welfare from an ex-ante point of view: public announcements serve as a focal point for higher-order beliefs and affect agents’...

We propose a speculative attack model in which agents receive multiple public signals. Diverse pieces of public information can be taken into account differently by different players and are likely to lead to different appreciations "ex post". This process defines players' expected private...

The model of Morris and Shin [2002] shows that imprecise public announcements can coordinate the actions of speculators far from the fundamental because of over-reaction to announcements. The strong focal potential of common knowledge is welfare damaging when it induces over-reaction to an...

Le modèle de Morris et Shin [2002] montre que des annonces publiques imprécises peuvent coordonner les spéculateurs loin de la solution fondamentale par un phénomène de sur-réaction aux annonces. Le fort potentiel focal exercé par la connaissance commune est dommageable au bien-être...
