A "fractal" solution to the chopstick auction

  • Christian Ewerhart

Abstract

This paper constructs a novel equilibrium in the chopstick auction of Szentes and Rosenthal (Games and Economic Behavior, 2003a, 2003b). In contrast to the existing solution, the identified equilibrium strategy allows a simple and intuitive characterization. Moreover, its best-response set has the same Hausdorff dimension as its support, which may be seen as a robustness property. The analysis also reveals some new links to the literature on Blotto games.
