Common Knowledge of a Multivariate Aggregate Statistic

International Economic Review, 1995, vol. 36, issue 1, 207-16

Abstract: If a stochastically monotone function of asymmetrically informed individuals' expectations of a random vector is common knowledge up to some observation error, then all the individuals must agree on their expectations. This result generalizes the 1986 theorem of R. D. McKelvey and T. Page from random variables to random vectors. It holds for general information structures given by sigma-algebras.
