This study provides new empirical evidence on the relationship between information about air pollution and avoidance behavior. Many countries provide real-time information to describe the current level of air pollution exposure. However, little research has been done on people’s reactions to that real-time information. Using data on attendance at professional baseball games in South Korea, this study investigates whether real-time information on particulate matter affects individuals’ decisions to participate in outdoor activities. Regression models that include various fixed effects are used for the analysis, with the results showing that real-time alerts reduce the number of baseball game spectators by 7%, and that the size of the effect is not statistically different from that of air pollution forecasts. The study demonstrates that providing real-time information can be a way to protect the public’s health from the threat of air pollution. Moreover, the findings suggest that having easy access to the relevant information and an awareness of the risks involved are necessary for a real-time information policy to succeed.

空气污染和回避行为的实时信息：来自韩国的证据

这项研究为空气污染信息与回避行为之间的关系提供了新的经验证据。许多国家提供实时信息来描述当前的空气污染暴露水平。然而，很少有人研究人们对实时信息的反应。本研究使用韩国职业棒球比赛的出席数据，调查颗粒物的实时信息是否会影响个人参与户外活动的决定。使用包含各种固定效应的回归模型进行分析，结果显示实时警报将棒球比赛的观众人数减少了 7%，并且效应的大小与空气污染预测的大小没有统计学差异. 该研究表明，提供实时信息可以成为保护公众健康免受空气污染威胁的一种方式。此外，调查结果表明，要使实时信息政策取得成功，必须轻松访问相关信息并了解所涉及的风险。
