Empirical Game Theoretic Analysis


In empirical game theoretic analysis (EGTA), the goal is to analyze or estimate various properties of a game, given only noisy blackbox (simulator) access to it.In particular, this means that we do not know the utility function of the game, and can only access samples of (per-player) utility values at any strategy profile (configuration of all player strategies) that, in expectation, match the utility of said profile.

Over the last several years, alongside my collaborators Amy Greenwald, and Enrique Areyan Viqueira, I have worked to bound the sample complexity of estimating equilibria and other properties of games in this setting. Furthermore, we have extended these ideas to mechanism design, wherein the goal is not just to estimate the properties of a game, but to modify a game or select its parameters in order to incentivize various types of strategic behavior and other desiderata.
