We characterize belief-free equilibria in infinitely repeated games with incomplete information with N \ge 2 players and arbitrary information structures. This characterization involves a new type of individual rational constraint linking the lowest equilibrium payoffs across players. The...

We analyze security price formation in a dynamic setting in which long-lived dealers repeatedly compete for trading with short-lived retail traders. We characterize equilibria in which dealers' dynamic pricing strategies are optimal no matter the private information each dealer may possess....
