摘要

无线紧急警报（WEAs）已成为向居民通报其附近潜在危险的重要信息系统。使用一个大型交易数据集，我们研究了(1)作为公共移动性的代理，WEAs如何影响离线和在线交易，以及(2)WEAs中不同类型的信息如何影响交易。我们的研究结果表明，与提供患者确切活动信息的WEAs相比，仅通知确诊病例发生的WEAs可以显着减少公共流动性。进一步的分析表明，此类WEAs的治疗效果在高收入地区更为明显。

Is ambiguity always adverse? Empirical evidence from the wireless emergency alerts during the pandemic

Wireless emergency alerts (WEAs) have become a crucial information system to notify residents of potential hazards in their vicinity. Using a large transaction dataset, we investigate (1) how WEAs influence offline and online transactions as a proxy to public mobility, and (2) how different types of information in WEAs affect transactions. Our results indicate that WEAs that only notify the occurrence of confirmed cases can significantly reduce public mobility compared to those that provide information on the exact movement of the patient. Further analysis suggests that the treatment effects of such WEAs are more pronounced in high-income areas.
