Risk aversion and COVID‐19 vaccine hesitancy
利用五个欧洲国家的大规模数据，研究了风险厌恶程度如何影响人们对COVID-19疫苗的犹豫态度，发现风险厌恶越高的人越不犹豫，说明他们觉得感染新冠的风险大于疫苗副作用的风险。
We here investigate the role of risk aversion in COVID-19 vaccine hesitancy. The theoretical effect is ambiguous, as both COVID-19 infection and vaccination side-effects involve probabilistic elements. In large-scale data covering five European countries, we find that vaccine hesitancy falls with risk aversion, so that COVID-19 infection is perceived as involving greater risk than is vaccination.
