讲座简介：

To address algorithmic bias, several fair machine learning algorithms that require equal impact (e.g.,equal opportunity) have been proposed. Compared with the prevailing algorithms that require equal treatment, fair ML algorithms are commonly perceived as “un”fair because they erode profits or welfare of certain parties and can never make everyone better off. Nevertheless, practical evidence from platform algorithms, such as LinkedIn Recruiter and Airbnb's smart pricing, counters the accusation of “un”fairness. To figure out why fair algorithms in platforms can make everyone better off, we develop a game-theoretic model where a platform, acting as an algorithm designer, provides algorithm services to a firm, functioning as the decision maker. The decentralization of algorithm designing and decision-making we considered has been overlooked in the existing literature on algorithmic decision-making. We find that whether fair algorithms (“un”)fair in platforms depends on the misclassification cost. When the misclassification cost is low, the fair ML algorithms are indeed fair that make everyone better off. When the misclassification cost is high, the fair ML algorithms are “un” fair that they make certain parties worse off.
