We prove existence and uniqueness of equilibrium in a 2-bidder asymmetric first price auction with affiliated values. The techniques used to prove uniqueness are different from the ones used in analyses of private values environments. Moreover the proof of existence is constructive. For...

This paper investigates information acquistion in decision problems. We introduce a new notion of "better information", Accuracy-order (A-order), defined on continuous families of signals. Accuracy formalizes the idea that "a signal that is more correlated with the unknown random variable is...

Several conceptual points are made concerning communication in games of asymmetric information. Equilibrium refinements of Sender-Receiver cheap-talk games that are based on he concept of a putative equilibrium, and which rely on the presence of a rich language with literal meanings, are...
