Christophe Chamley, « Strategic complementarity of information in financial markets with large shocks », HALSHS : archive ouverte en Sciences de l’Homme et de la Société, ID : 10.1007/s10436-009-0130-1
In a simple model of a frictionless financial market with rational agents, the value of private information increases when large discrete shocks independently affect the fundamental value of the asset and the exogenous trading. The complementarity in information gathering generates multiple equilibria.
