Title: "Uncertainty, Bounded Rationality, and Strategic Voting"
Abstract:
I will describe a novel model for representing uncertainty in multi-player games, inspired by bounded-rationality and modal logic. More specifically, each player holds an uncertain, non-probabilistic, view of other players' actions.
While the model is quite general, I will focus on the widely-used Plurality voting rule, showing that the model has three main advantages over previous theories:
(a) the optimal strategy of a voter reduces to a natural heuristic;
(b) a voting equilibrium always exists, and is reached by any best-response dynamics; and
(c) extensive simulations show that the resulting equilibria replicate known phenomena from real-world voting.
Time permits, I will discuss how a similar approach to uncertainty can be applied to understand strategic behavior in very different settings, including scheduling on Doodle and routing in networks.
The talk is based on joint works with Omer Lev, David Parkes, Jeffrey S. Rosenschein, and James Zou.
