First-See-Then-Design: A Multi-Stakeholder View for Optimal Performance-Fairness Trade-Offs

Summary

A new multi-stakeholder framework for fair algorithmic decision-making has been proposed, shifting focus from prediction-centric fairness to a justice-based approach. This framework explicitly models the utilities of both the decision-maker (DM) and decision subjects (DS), defining fairness through a social planner's utility that quantifies inequalities in DS utilities across groups, incorporating notions like Egalitarian or Rawlsian justice. The approach formulates fair decision-making as a post-hoc multi-objective optimization problem, mapping performance-fairness trade-offs in a two-dimensional utility space for DM and social planner utilities. It also explores different decision policy classes, including deterministic and stochastic, and shared versus group-specific policies. The research identifies conditions under which stochastic policies outperform deterministic ones, empirically showing that simple stochastic policies can achieve superior performance-fairness trade-offs by utilizing outcome uncertainty.

Key takeaway

For AI Ethicists and Research Scientists designing fair algorithms, you should consider adopting a multi-stakeholder framework that explicitly models utilities for both decision-makers and subjects. Moving beyond prediction-centric fairness to a justice-based approach, potentially incorporating stochastic policies, can yield more optimal performance-fairness trade-offs and support a more collaborative design process for decision-making policies.

Key insights

Fair algorithmic decision-making requires a multi-stakeholder, justice-based view beyond predictive fairness.

Principles

• Fairness should consider DM and DS utilities.
• Social planner utility captures group inequality.
• Stochastic policies can improve trade-offs.

Method

The framework models DM and DS utilities, defines fairness via a social planner's utility, and formulates fair decision-making as a post-hoc multi-objective optimization problem to characterize performance-fairness trade-offs.

In practice

• Model decision-maker and subject utilities.
• Evaluate stochastic vs. deterministic policies.
• Incorporate justice-based fairness notions.

Topics

• Multi-stakeholder Fairness
• Algorithmic Decision-Making
• Welfare Economics
• Distributive Justice
• Performance-Fairness Trade-Offs
