Analysis of efficiency of outcomes in game theoretic settings has been a main item\u00a0of study at the intersection of economics and computer science. The notion of\u00a0the price of anarchy takes a worst-case stance to efficiency analysis, considering\u00a0instance independent guarantees of efficiency. We propose a data-dependent analog\u00a0of the price of anarchy that refines this worst-case assuming access to samples of\u00a0strategic behavior. We focus on auction settings, where the latter is non-trivial\u00a0due to the private information held by participants. Our approach to bounding the\u00a0efficiency from data is robust to statistical errors and mis-specification. Unlike\u00a0traditional econometrics, which seek to learn the private information of players
\nfrom observed behavior and then analyze properties of the outcome, we directly\u00a0quantify the inefficiency without going through the private information. We apply\u00a0our approach to datasets from a sponsored search auction system and find empirical\u00a0results that are a significant improvement over bounds from worst-case analysis.<\/p>\n","protected":false},"excerpt":{"rendered":"
