This paper shows that the efficiency bound for communication equilibria identified by Goltsman et al. (2009) in the leading example of the Crawford–Sobel model can be obtained with strategy-correlated equilibria, thus preserving privacy vis-à-vis the mediator. More generally, all equilibrium...

This paper completely characterizes the set of equilibria of the Vickrey auction for multiple identical units when buyers have non-increasing marginal valuations and there are at least three potential buyers. There are two types of equilibria: In the first class of equilibria there are positive...

This paper investigates optimal play in coordination games in which cognition plays an important role. In our game logically omniscient players would be able to identify a distinct coordination opportunity from other obvious facts. Real players may be unable to make the required inference. Our...

We advance the measurement of trust in economics in two ways. First, we highlight the importance of clearly identifying the target of trust, particularly for obtaining concordance between attitudinal and behavioral measures of trust. Second, we introduce a novel behavioral measure of (dis)trust,...
