Abstract
The present study examines a specific type of referee biases, home bias, and analyzes how the presence of fans affects home bias by using NBA games played in empty arenas during the COVID-19 pandemic in the 2020-2021 season and matches played before the pandemic from 2017 to 2020. This research also uses a unique data set from NBA Last Two Minute Reports to assess referees' performance at the play level. The findings show crowd support does not cause referees to treat home and away teams differently in crucial situations during the NBA regular season, contrary to the results in most prior studies.
本研究通过 2020-2021 赛季 COVID-19 大流行期间在空场进行的 NBA 比赛以及 2017-2020 年大流行之前进行的比赛，研究了裁判偏见的一种特殊类型--主场偏见，并分析了球迷的存在如何影响主场偏见。这项研究还使用了来自 NBA 最后两分钟报告的独特数据集，以评估裁判在比赛层面的表现。研究结果表明，在 NBA 常规赛期间，观众的支持并不会导致裁判在关键情况下区别对待主队和客队，这与之前大多数研究的结果相反。
