Rather doomed than uncertain: risk attitudes and transmissive behavior under asymptomatic infection
研究了面对无症状传染病时，个体的风险厌恶程度如何影响其暴露于感染风险的意愿，发现高患病率环境下风险厌恶反而增加传播行为，并通过实验室实验验证。
We analyze the relation between individuals' risk aversion and their willingness to expose themselves to infection when faced with an asymptomatic infectious disease. We show that in a high prevalence environment, increasing individuals' risk aversion increases their propensity to engage in transmissive behavior. The reason for this result is that as risk aversion increases, exposure which leads to infection with certainty becomes relatively more attractive than the uncertain payoffs from protected behavior. We provide evidence from a laboratory experiment which is consistent with our theoretical findings.
