We analyze habit formation in sports attendance utilizing rainfall as an unexpected, transitory shock to attendance costs. Using attendance data from Major League Baseball (MLB) and National Oceanic and Atmospheric Administration weather data, we analyze the impact of variation in game day weather conditions on current and future MLB attendance. The empirical strategy permits identification of both the formation and persistence of habit from exogenous weather shocks. Past adverse weather shocks increase future attendance by about 200 fans per game. This contributes to the literature developing empirical evidence of habit formation in the field and provides policy implications for optimal ticket-pricing strategies.

天气会受到天气影响吗？降雨，习惯形成和现场游戏出席

我们使用降雨作为出勤成本的意外，短暂冲击来分析体育出勤中的习惯形成。使用来自美国职棒大联盟（MLB）的出勤率数据和国家海洋与大气管理局的气象数据，我们分析了比赛日天气条件变化对当前和未来MLB出勤率的影响。该经验策略允许识别外源性天气冲击引起的习惯的形成和持久性。过去不利的天气冲击使每场比赛的未来出勤人数增加约200名。这有助于文献开发实地习惯形成的经验证据，并为最佳机票定价策略提供政策含义。
