Sequential price of anarchy
Web6 Dec 2024 · This ratio is known as the sequential price of anarchy (SPoA). We also introduce two alternative inefficiency measures, which allow for a favorable choice of the order in which the jobs make... In a sequential auction, items are sold in consecutive auctions, one after the other. The common equilibrium type is subgame perfect equilibrium in pure strategies (SPEPS). When the buyers have full information (i.e., they know the sequence of auctions in advance), and a single item is sold in each round, a SPEPS always exists. The PoA of this SPEPS depends on the utility functions of the bidders, and on the type of auctio…

WebWe show that for two players, the sequential price of anarchy equals 1.5, and for three players it equals approximately 2.13. While the case with two players is analyzed analytically, the tight bound for three players is based on the explicit computation of a worst-case instance using linear programming.
