那么,邻居、同事和路人他们这些人呢?因为戴口罩对别人的好处远远大于对我们自己的好处,所以戴口罩的正外部性是巨大的与此相一致的是,几项研究认为,戴口罩不仅经济成本很小,而且对健康好处很大利记体育app_利记体育app网址_利记体育app平台然而,基础经济学告诉我们,自私自利的决策者不会愿意戴口罩美国爆发的反口罩游行示威视频截图保持社交距离也差不多是如此

我们都知道保持距离很不方便,尤其是当其他人不配合的时候这肯定会阻碍经济活动利记体育app_利记体育app网址_利记体育app平台然而,没有人会奖励那些与他人保持适当距离的人,也很少有地方会惩罚那些离别人太近的人和口罩的情况类似,自由市场中的个人决策将导致社交距离的缩短补救外部性的标准做法是征税或补贴

但对于戴口罩和保持社交距离而言,这又不切实际最好的办法可能是强制要求人们戴上口罩、在公共场合保持社交距离,这执行起来会很困难,但在一些州和很多欧洲国家,这么做是有效的利记体育app_利记体育app网址_利记体育app平台然而,这时我们又听到了右翼的怒吼——包括一些共和党州长——声称戴口罩或保持距离都是“对个人自由的侵犯”呵呵,当然,红灯和限速也“侵犯个人自由”,但它们和口罩一样,都可以拯救生命毫不夸张地说:反对戴口罩的人,都在杀人

本文是8月12日刊自《华尔街日报》的专栏文章,其评论区讨论十分激烈,观察者网对其部分摘录如下:凯文·伯恩斯:很遗憾,我们很多人其实是意识到了风险所在,我们反对的点在于,许多政府颁布的政令很蠢利记体育app_利记体育app网址_利记体育app平台就在我们周围,比如说,超过25个人可以同乘一辆公交车,却不允许超过25个人同在一间教堂内布莱恩·凯尼格:那瑞典又怎么说?这名经济学教授提议的一切他们都没做,不也一样过得很好?南森·斯莫利回复:瑞典的死亡率是其邻国的10倍

过得很好?去看看德国吧约翰·坎菲尔德:我们H1N1流感期间不也不戴口罩?猪流感期间不也不戴?埃博拉?每个冬天的流感季?问问你朋友去利记体育app_利记体育app网址_利记体育app平台基思·瓦格纳回复:因为这些都未形成彻底失控的大流行帮个忙,控制下病毒、带个口罩吧,别再把戴口罩这事政治化了乔治·卡纳汉回复:戴口罩已经被政治化了
