A Deterministic Protocol for Sequential Asymptotic Learning
Yu Cheng, Wade Hann-Caruthers, Omer Tamuz
In the classic herding model, agents receive private signals about an underlying binary state of nature, and act sequentially to choose one of two possible actions, after observing…
Quasi-regular sequences and optimal schedules for security games
David Kempe, Leonard J. Schulman, Omer Tamuz
We study security games in which a defender commits to a mixed strategy for protecting a finite set of targets of different values. An attacker, knowing the defender's strategy, ch…
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…
Lower Bounds on Revenue of Approximately Optimal Auctions
Balasubramanian Sivan, Vasilis Syrgkanis, Omer Tamuz
We obtain revenue guarantees for the simple pricing mechanism of a single posted price, in terms of a natural parameter of the distribution of buyers' valuations. Our revenue guara…
Strategic Learning and the Topology of Social Networks
Elchanan Mossel, Allan Sly, Omer Tamuz
We consider a group of strategic agents who must each repeatedly take one of two possible actions. They learn which of the two actions is preferable from initial private signals, a…
A lower bound on seller revenue in single buyer monopoly auctions
Omer Tamuz
We consider a monopoly seller who optimally auctions a single object to a single potential buyer, with a known distribution of valuations. We show that a tight lower bound on the s…
