Title:
Comparison of Oracles
Abstract:
We analyze incomplete-information games where an oracle publicly shares information with players. One oracle dominates another if, in every game, it can match the set of equilibrium outcomes induced by the latter. Distinct characterizations are provided for deterministic and stochastic signaling functions, based on simultaneous posterior matching, partition refinements, and common knowledge components. This study extends thework of Blackwell (1951) to games, and expands the study of Aumann (1976) on common knowledge by developing a theory of information loops.
