Abstract:
We develop a sufficient-statistic approach to designing collaborative human-AI decision-making policies in classification problems, where AI predictions can be used to either automate decisions or selectively assist humans. The approach allows for endogenous and biased beliefs, and effort crowd-out, without imposing a structural model of human decision-making. We deploy and validate our approach in an online fact-checking experiment. We find that humans under-respond to AI predictions and reduce effort when presented with confident AI predictions. AI under-response stems more from human overconfidence in own-signal precision than from under-confidence in AI. The optimal policy automates cases where the AI is confident and delegates uncertain cases to humans while fully disclosing the AI prediction. Although automation is valuable, the additional benefit from assisting humans with AI predictions is negligible.

The AImpact Center is dedicated to exploring the effects of artificial intelligence and digital technologies on society. It aims to understand and address the ethical, social, and economic implications of these technologies, ensuring they benefit all members of society. The center is sponsored by the Department of Economics, School of Information Sciences, and Siebel School of Computing and Data Science.
