Abstract

We study an index to measure the popularity of artists in music streaming platforms. This index, which can be used to allocate the amount raised via paid subscriptions among participating artists, is based on the Shapley value, a centerpiece in cooperative game theory. We characterize this Shapley index combining several axioms formalizing principles with normative appeal. This permits to place the index in the literature, as an alternative to the well-known (and widely used in the industry) pro-rata and user-centric indices.

音乐流媒体平台的Shapley指数

我们研究了一个指数来衡量艺术家在音乐流媒体平台上的受欢迎程度。该指数基于合作博弈论的核心要素沙普利值（Shapley value），可用于在参与的艺术家之间分配通过付费订阅筹集的资金。我们结合几个具有规范性吸引力的形式化原则的公理来描述这个沙普利指数。这允许将索引放置在文献中，作为众所周知的（在业界广泛使用的）按比例和以用户为中心的索引的替代方案。
