In a private private information structure, agents’ signals contain no information about the signals of their peers. We study how informative such structures can be, and characterize those that are on the Pareto frontier, in the sense that it is impossible to give more information to any agent without violating privacy. In our main application, we show how to optimally disclose information about an unknown state under the constraint of not revealing anything about a correlated variable that…

This text was born out of an advanced mathematical economics seminar at Caltech in 1989-90. We realized that the typical graduate student in mathematical economics has to be familiar with a vast…
Correlated Equilibrium in Two-Person Zero-Sum Games

This paper studies sets S in $\mathbb{R}''$ which are uniquely reconstructible from their hyperplane integral projections $P_i ( {x_i ;S} ) = \iint { \cdots \int {\chi _S } }( {x_1 , \cdots ,x_i ,…

Existence of Probability Measures With Given Marginals
We show that if $f$ is a probability density on $R^n$ wrt Lebesgue measure (or any absolutely continuous measure) and $0 \leq f \leq 1$, then there is another density $g$ with only the values 0 and 1…

Feasible Joint Posterior Beliefs
TLDR
A quantitative version of Aumann's Agreement Theorem provides a necessary and sufficient condition for feasibility for the two-agent case and for any number of agents, a related "no-trade" condition likewise provides a characterization of feasibility.
Cheating with Models
Beliefs and decisions are often based on confronting models with data. What is the largest “fake” correlation that a misspecified model can generate, even when it passes an elementary…
