On time-consistent equilibrium stopping under aggregation of diverse discount rates

Shuoqing Deng, Xiang Yu, Jiacheng Zhang

This paper studies a central planner's decision making on behalf of a group of members with diverse discount rates. In the context of optimal stopping, we work with an aggregation…

Major-Minor Mean Field Game of Stopping: An Entropy Regularization Approach

Xiang Yu, Jiacheng Zhang, Keyu Zhang +1

This paper studies a discrete-time major-minor mean field game of stopping where the major player can choose either an optimal control or stopping time. We look for the relaxed equ…

Minimax-optimal trust-aware multi-armed bandits

Changxiao Cai, Jiacheng Zhang

Multi-armed bandit (MAB) algorithms have achieved significant success in sequential decision-making applications, under the premise that humans perfectly implement the recommended…
