This paper exploits a sharp regression discontinuity design to identify the causal impact of the Scottish Premiership League (SPL) “split” on spectator match attendance. We use data drawn from all 19 completed seasons for which this institutional arrangement has been in place. The causal effect of the “split” is to induce, for the last five rounds of games played in the season, a differential in average attendance of about 24% between the clubs that just qualify for the “Championship Play-off” section and those that do not. However, the annualized effect for the season is found to be modest.

联赛设计对观众出勤率的影响：回归不连续性设计方法

本文利用一种尖锐的回归不连续性设计来确定苏格兰超级联赛（SPL）“分裂”对观众比赛出勤率的因果影响。我们使用从已经完成此制度安排的所有19个完整季节中获得的数据。“分拆”的因果关系是，在该赛季的最后五轮比赛中，导致仅符合“锦标赛附加赛”部分的俱乐部与那些参加该锦标赛的俱乐部之间的平均出勤率相差约24％。那没有。但是，发现该季节的年度化影响不大。
