We consider a single-blinded experimental design, in which the provision of AI-generated recommendations is randomized across cases with a human making final decisions.

We consider optimal policy learning with asymmetric counterfactual utility functions of this form that consider the joint set of potential outcomes.

We extend this approach to common and important settings where humans make decisions with the aid of algorithmic recommendations.

Using the concept of principal stratification from the causal inference literature, we introduce a new notion of fairness, called principal fairness, for human and algorithmic decision-making.
