Научный семинар МИЭФ, Peio Zuazo-Garin (University of the Basque Country)

В четверг, 15 марта в 16.40 в ауд. 3211 (ул. Шаболовка, 26) прошел научный семинар МИЭФ. 
Докладчик: Peio Zuazo-Garin (University of the Basque Country)
Тема доклада: "Rationalizability and Observability" совместно с Antonio Penta

Тезисы доклада: We study the strategic impact of players' higher order uncertainty over whether their actions are observable to their opponent. We characterize the "robust predictions" of Rationality and Common Belief in Rationality (RCBR), i.e. those which do not depend on the restrictions on players' infinite order beliefs over the extensive form. We show that RCBR is generically unique, and that the robust predictions often support a robust refinement of rationalizability. For instance, in unanimity games, the robust predictions of RCBR rule out any inefficient equilibrium action; in zero-sum games, they support the maxmin solution, solving a classical tension between RCBR and the maxmin logic; in common interest games, RCBR generically ensures efficient coordination of behavior, thereby showing that higher order uncertainty over the extensive form serves as a mechanism for equilibrium coordination on purely eductive grounds.
