Incentive Compatibility: Everywhere vs. Almost Everywhere∗
A risk neutral buyer observes a private signal s ∈ [a, b], which informs her that the mean and variance of a normally distributed risky asset are s and σ s respectively.

If B = ∅, then there exists a fully revealing equilibrium in whic...

Mutualism is often stronger when resources are scarce, but th...
