Abstract

Stochastic incentive design problems entail hierarchical stochastic decision-making between a leader and a single (or multiple) follower(s) with possibly different goals. The leader seeks to induce a desired behavior from one or more followers through a soft policy that penalizes the followers for deviating from her desired responses, but the penalty varies smoothly in said deviations. Such problems arise in different contexts, such as designing tax codes and imposing environmental regulations on corporations. The design of such policies relies on the knowledge of followers’ costs and observations. In the first part of this talk, I will present our recent results on incentive design when such knowledge on costs and observations are relaxed. The key conclusion of this part is that the leader can still roughly induce the desired behavior from the followers under reasonable assumptions. In the second half of the talk, I will discuss the question of incentive design with many followers and its mean-field limits. A perhaps surprising result of this part is that mean-field limits of such Stackelberg games are not well-defined. I will discuss a variant of the original game that admits such limits. I will conclude the talk with ongoing work on learning follower’s costs in repeated incentive design settings.
