This paper analytically examines the demand for surgical masks following the recent health precautions due to coronavirus. Using a simple linear demand curve and alternatively examining the impacts of requirements that mandate (a) the wearing of masks by frontline workers; (b) suggested but not required masking by the whole public; and (c) compulsory masking by the whole public. The impacts of the different scenarios on the price elasticity of demand are determined along with the slope (or the rate of change) of elasticity. Some of these results differ when a non-linear demand curve is considered instead. The equilibrium mask prices increase when masks are universally mandated, whereas the consumer surplus is higher when masks are recommended but not mandated. However, the ranking of consumer surplus is shown to be sensitive to the supply elasticity of masks. These considerations enable a structured means to view the demand implications of masking requirements and provide some food for policy thought.
本文通过分析研究了在近期因冠状病毒采取健康预防措施后对医用口罩的需求。使用一条简单的线性需求曲线,并交替考察以下要求的影响:(a)一线工作人员佩戴口罩;(b)建议而非强制全体公众佩戴口罩;(c)强制全体公众佩戴口罩。确定了不同情景对需求价格弹性的影响以及弹性的斜率(或变化率)。当考虑非线性需求曲线时,其中一些结果会有所不同。当口罩被普遍强制要求佩戴时,均衡口罩价格会上涨,而当口罩只是被建议而非强制佩戴时,消费者剩余会更高。然而,消费者剩余的排名显示出对口罩供应弹性很敏感。这些考量提供了一种结构化的方式来审视口罩佩戴要求对需求的影响,并为政策思考提供了一些思路。
