Researchers have developed a new approach to the dynamic principal-agent problem, which involves a principal designing contracts for an agent with unknown preferences and hidden actions. By introducing stochasticity into the agent's utility model, the team restored continuity to the principal's expected utility, enabling a formulation as a structured multi-armed bandit problem. Their proposed Heteroscedastic GP-UCB algorithm, utilizing a Neural Network (Arcsin) kernel, achieves a cumulative regret bound of O(sqrt(T)(log T)^(m+1)) for an m-dimensional contract space. This framework was successfully applied to the Vehicle-to-Grid (V2G) incentive design problem, demonstrating superior economic performance for grid aggregators. AI
