Broadcasting revenue sharing after cancelling sports competitions
研究新冠疫情导致体育赛事取消后，如何通过公理化方法调整转播收入的分配规则，重点分析了两种扩展算子（零算子和联盟算子）下的等分规则与让步分配规则。
Abstract The COVID-19 pandemic forced the partial or total cancellation of most sports competitions worldwide. Sports organizations crucially rely on revenues raised from broadcasting. How should the allocation of these revenues be modified when sports leagues are cancelled? We aim to answer that question in this paper by means of the axiomatic approach. Two extension operators (dubbed zero and leg operators, respectively) will play a major role in our analysis. We show that several combinations of axioms (formalizing ethical or strategic principles) characterize the image via those operators of two focal rules: the equal-split rule and concede-and-divide .
