This paper assesses the effect of the crowd size on home team advantage, using a natural experiment occurred in Brazilian football. In 2015, the Brazilian Football Confederation (CBF) quasi-randomly assigned games to be played under an alternative schedule on Sundays at 11 a.m. This measure significantly increased attendance in assigned games. Using this alternative schedule as an instrumental variable, we show that the exogenous increase in attendance did not increase home team advantage.

粉丝和比赛结果：巴西自然实验的证据

本文使用巴西足球进行的自然实验评估了人群规模对主队优势的影响。2015年，巴西足球联合会（CBF）准随机分配的比赛将在周日的上午11点按其他时间表进行。此措施大大增加了指定比赛的出勤率。使用此替代时间表作为工具变量，我们显示出场人数的外来增加并没有增加主队的优势。
