Bayesian Nash equilibrium in all-pay auctions with interdependent types

Author

  • Haimanko, Ori

Abstract

We prove the existence of a behavioral-strategy Bayesian Nash equilibrium in all-pay auctions with statistically interdependent types (signals) under quite general assumptions on the values, costs and tie-breaking rules. Moreover, the set of equilibria is shown to be the same for any tie-breaking rule used in the auction.
