Although many fairness criteria have been proposed for decision making, their long-term impact on the well-being of a population remains unclear. In this work, we study the dynamics of population qualification and algorithmic decisions under a partially observed Markov decision problem setting. By characterizing the equilibrium of such dynamics, we analyze the long-term impact of static fairness constraints on the equality and improvement of group well-being. Our results show that static fairness constraints can either promote equality or exacerbate disparity depending on the driving factor of qualification transitions and the effect of sensitive attributes on feature distributions. We also consider possible interventions that can effectively improve group qualification or promote equality of group qualification. Our theoretical results and experiments on static real-world datasets with simulated dynamics show that our framework can be used to facilitate social science studies.

本文针对决策公平性方面的长期影响进行研究，研究人员通过模拟静态公平约束下群体福祉的平等和改进的长期影响以及潜在的干预措施，发现其对于群体福利可同时具有促进平等和增加差距两种影响，同时提出一种理论框架并完成了基于实际数据与模拟动态的社会科学研究。
