Abstract

The purpose of this work is to identify the factors that form the market value of a football player. The study tests hypotheses about the influence of individual characteristics (age, height, weight), statistical performance indicators from local and international competitions both at the club level and at the national team level, expert assessments from the FIFA sports simulator, as well as injury history on the transfer value of a player, the number of days until the expiration of the contract, the number of transfers and the characteristics of the player’s agent. The selection of variables for the final models is made according to statistical criteria, as well as using Lasso and Ridge regressions. The analysis uses a linear model as well as a Heckman model in various specifi cations. The study showed a signifi cant negative impact of injuries on the cost of a football player (a day in the hospital — 0.2% of the cost) and a positive impact of goals in EuroCups. In addition, the influence of agents on the cost of transfers of football players was revealed: large agencies reduce the cost of a transfer by 8%, other things being equal, but increase the probability of a transfer by 2%. The effect of "Neymar" is substantiated: prices in the football market after the transfer of a football player increased by an average of more than 20%. Peculiarities in the transfer policy of the clubs that planned to organize the "Super League" were also revealed.
影响足球俱乐部转会政策的因素
这项工作的目的是确定形成足球运动员市场价值的因素。该研究测试了个人特征(年龄、身高、体重)、俱乐部和国家队本地和国际比赛的统计表现指标、国际足联体育模拟器的专家评估以及伤病史对球员转会价值、合同到期天数、转会次数和球员经纪人特征的影响的假设。根据统计标准选择最终模型的变量,并使用Lasso和Ridge回归。分析使用了线性模型和各种规格的Heckman模型。研究表明,伤病对足球运动员的成本有显著的负面影响(住院一天占成本的0.2%),而对欧洲杯的进球有积极影响。此外,还揭示了经纪人对足球运动员转会成本的影响:在其他条件相同的情况下,大型经纪人会使转会成本降低8%,但会使转会概率增加2%。“内马尔”的影响得到了证实:一名足球运动员转会后,足球市场的价格平均上涨了20%以上。计划举办“超级联赛”的俱乐部在转会政策上的特殊性也被揭露出来。
