Testing, Voluntary Social Distancing, and the Spread of an Infection
研究了增加检测可能带来的意外行为后果：更多检测会减少自愿社交距离或增加社交活动，从而加剧病毒传播，且检测对感染的影响是非单调的。
A standard policy to reduce the spread of infection is increasing the use of testing that enables the isolation of infected individuals, slowing down the infection. In “Testing, Voluntary Social Distancing, and the Spread of an Infection,” the authors argue the possibility of unintended behavioral consequences from increased testing: greater testing reduces voluntary social distancing or increases social activity, exacerbating the spread of the virus. They show that the effect of testing on infections is nonmonotone. This nonmonotonicity also implies that the optimal testing policy may leave some of the testing capacity of society unused and that increasing testing should be used together with mandatory social distancing to reduce the spread of infection.
