We define a cautious version of extensive-form rationalizability for generalized extensive- form games with unawareness that we call prudent rationalizability. It is an extensive-form analogue of iterated admissibility. In each round of the procedure, for each tree and each information set of a...

This paper performs a welfare analysis of economies with private information when public information is endogenously generated and agents can condition on noisy public statistics in the rational expectations tradition. We find that equilibrium is not (restricted) efficient even when feasible...

This paper performs a welfare analysis of markets with private information in which agents can condition on noisy prices in the rational expectations tradition. Price-contingent strategies introduce two externalities in the use of private information: a payoff (pecuniary) externality related to...

We propose an incomplete information analogue of rationalizability. An action is said to be belief-free rationalizable if it survives the following iterated deletion process. At each stage, we delete actions for a type of a player that are not a best response to some conjecture that puts weight...
