Uncertainty in the Traveler's Dilemma

Abstract

The paper analyzes a perturbation on the players’ knowledge of the game in the traveler’s dilemma, by introducing some uncertainty about the range of admissible actions. The ratio between changes in the outcomes and the size of perturbation is shown to grow exponentially in the range of the given game. This is consistent with the intuition that a wider range makes the outcome of the traveler’s dilemma more paradoxical. We compare this with the growth of the elasticity index (Bavly (2011)) of this game.
