LEAGUE‐LEVEL ATTENDANCE AND OUTCOME UNCERTAINTY IN U.S. PRO SPORTS LEAGUES

We extend the breakpoint literature regarding annual league‐level attendance and the impact of outcome uncertainty to the National Basketball Association, National Football League, and National Hockey League. As our measures are different than past work on baseball, we also apply our model to the American and National Leagues. Attendance series for each league under consideration are not stationary overall, but are stationary with break points. No form of outcome uncertainty (game, play‐off, or across seasons) matters for attendance in hockey or baseball regardless of which game uncertainty variable is used. Under the measure of game uncertainty that recommends itself for football, only play‐off uncertainty matters for attendance. Whether outcome uncertainty matters for basketball depends on the measure of game uncertainty. Situational similarities in the break points across leagues suggest general areas for future research.
