Economic theory predicts that in a first-price auction with equal and observable valuations, bidders earn zero profits. Theory also predicts that if valuations are not common knowledge, then since it is weakly dominated to bid your valuation, bidders will bid less and earn positive profits....

Aumann(1976) has shown that agents who have a common prior cannot have common knowledge of their posteriors for event E if these posteriors do not coincide. But given an event E, can the agents have posteriors with a common prior such that it is common knowledge that the posteriors for E *do*...

We analyze an economy with asymmetric information and endogenize the possibilities for information transmission between members of a coalition. We then define a concept of the Core that takes into account these communication possibilities. The internal consistency of the improvements is...

The RVT predicts equilibrium prices in a world where investors ignore variance and only care about cumulative returns. Such prices determine intrinsic returns that satisfy the CAPM equation. This paper shows that assets that pay a constant (or constantly increasing) dividend but face each year...

The Relative Value Theory predicts equilibrium prices in a world in which time value of money is unique, and investors are risk-indifferent and only care about maximizing cumulative returns. This paper shows that RVT’s equilibrium prices determine intrinsic expected returns that satisfy the...

This paper examines the concepts of trust and trustworthiness in the context of a one-sided variation of the prisoner's dilemma, and it evaluates four different categories of solutions to the PD problem: changing player preferences, enforcing explicit contracts, establishing implicit contracts,...
