Rational Groupthink
Matan Harel, Elchanan Mossel, Philipp Strack +1
We study how long-lived rational agents learn from repeatedly observing a private signal and each others' actions. With normal signals, a group of any size learns more slowly than…
Transitive graphs uniquely determined by their local structure
Joshua Frisch, Omer Tamuz
We show that the "grandfather graph" has the following property: it is the unique completion to a transitive graph of a large enough finite subgraph of itself.
Property (T) and the Furstenberg Entropy of Nonsingular Actions
Lewis Bowen, Yair Hartman, Omer Tamuz
We establish a new characterization of property (T) in terms of the Furstenberg entropy of nonsingular actions. Given any generating measure on a countable group , A. Nevo s…
Convergence, unanimity and disagreement in majority dynamics on unimodular graphs and random graphs
Itai Benjamini, Siu-On Chan, Ryan O'Donnell +2
In majority dynamics, agents located at the vertices of an undirected simple graph update their binary opinions synchronously by adopting those of the majority of their neighbors.…
Generic Stationary Measures and Actions
Lewis Bowen, Yair Hartman, Omer Tamuz
Let be a countably infinite group, and let be a generating probability measure on . We study the space of -stationary Borel probability measures on a topological …
Graphical potential games
Yakov Babichenko, Omer Tamuz
We study the class of potential games that are also graphical games with respect to a given graph of connections between the players. We show that, up to strategic equivalence,…
