Inequality of Profits among Clubs in Japanese Football League
Professional sports are always required to win. In order to win, it is necessary for the club to obtain highly competent players and supervisors with achievements, but it is costly to keep those personnel. In this paper we analyze relationships between allocation fees and rankings, income and expenses, players’ annual salaries and scored points, scored points and operating revenues and operating expenses based on J. League member clubs’ individual disclosure documents released every year from 2006 to 2016. The results imply that clubs other than the top ranking would descend gradually from the competition, and differences in revenue, number of victories, and scored points between the top-ranking group and other groups will spread further in the future.
