Abstract

We show that the use of communications to coordinate equilibria generates a Nash-threats folk theorem in two-player games with “almost public” information. The results generalize to the n-person case. However. the two-person case is more difficult because it is not possible to sustain equilibria by comparing the reports of different players. and using these “third parties” to effectively enforce contracts.
