球團老闆是冤大頭嗎?球員合約價值的決定因子─以美國職籃(NBA)為例

Did the Boss Pay Too Much?: A Determinant Model for Basketball Players' Contract Value: Empirical Evidence from the National Basketball Association

摘要


目的:本研究將透過複迴歸分析法,評估2015-16到2018-19共4個賽季,美國職籃球員績效表現對於其新簽約的價值是否有顯著影響。方法:本文採用的研究方法為迴歸分析模型。結果:依據本文的實證研究結果顯示,球員的契約價值與其場上綜合表現有顯著關係。這些績效包括球員效益值、預估勝場貢獻,和真實正負值。結論:依據此一模型,讓球團可評估球員績效表現與其合約價值之間的關聯性。

Purpose: Because of the enormous popularity of US professional basketball (particularly the National Basketball Association, or NBA), numerous teams compete to sign large contracts with the most valuable players. This phenomenon causes doubt as to whether the owners of these teams are paying their players too much. When a team owner pays a large sum for a player contract but the player does not majorly benefit the team in that season, the owner becomes a "Head of Injustice." Methods: This study employs multiple regression analysis to investigate the relationship between US NBA basketball players' performance and contract value from the 2015-2016 to 2018-2019 seasons. Results: Our empirical results reveal that an NBA player's contract value is significantly correlated with his performance as measured using his player efficiency rating, estimated wins added, and real plus minus.
