Sporting leagues have various competitive balance measures including player drafts, where teams are awarded picks based on prior performance. Teams, however, have the option to either exercise this pick or trade it as they see fit. An analysis of this trading market in the NFL stated that players obtained through traded picks contributed more to their recruiters in comparison to their counterparts. This paper retested this within the AFL and disproved this fact, establishing the Coasian notion of the efficient allocation of resources, based on some differences between the list management systems between the two leagues.

AFL选秀交易市场作为科斯塔乌托邦

体育联盟具有各种竞争平衡措施，包括球员选秀，在此基础上，球队将根据先前的表现获得选秀权。但是，团队可以选择行使此选择权或根据自己的意愿进行交易。对NFL中这个交易市场的分析表明，与交易对手相比，通过交易选秀权获得的球员对招聘者的贡献更大。本文基于AFL的名单管理系统之间的某些差异，在AFL中对此进行了重新测试，并反驳了这一事实，确立了有效分配资源的Coasian概念。
