The Price of Anarchy of Two-Buyer Sequential Multiunit Auctions

Web27 Feb 2024 · For general valuation functions, we show that the price of anarchy is exactly 1/T for auctions with T items for sale. For concave valuation functions, we show that the price of anarchy is bounded below by 1 − 1/e ≃ 0.632. This bound is asymptotically tight as the number of items sold tends to infinity. WebThe sequential prices of anarchy is then a lower bound on the quality of any subgame perfect equilibrium of such a game relative to the quality of the global optimum. This idea was introduced in a recent paper by Paes Leme, Syrgkanis, and Tardos, where they indeed give examples where sequential decision making leads to better equilibria. ... is isawitfirst a uk company https://odlin-peftibay.com
