Value of information in competitive economies with incomplete markets
A substantial literature addresses the negative eect on welfare of the release of information in a competitive market economy. We show that the value of information in this setting is typically positive if asset markets are suciently incomplete. More specically, for any competitive equilibrium of a generic economy, we can nd a ner information structure such that an allocation that is resource feasible and measurable with respect to this information ex- post Pareto dominates the given equilibrium allocation.
