Covid-19 pandemic is exerting a tragic impact all around the world. First-person experience of life-threatening and stressful events can modify individuals' risk perception, and, consequently, risk-taking behaviours. Here we investigated risk-taking profiles in 130 Italian residents, and compared healthcare to non-healthcare workers, during the lockdown phase. We ad hoc developed the "Covid-19 Risk Task", including the classic monetary Holt-Laury Paired Lottery Task (Monetary Condition, MC) and two new ecological conditions exploring Covid-19 related risk-taking aptitudes in relation to different health (Health Status Condition, HsC) and employment (Employment Status Condition, EsC) outcomes. Results showed that, in the whole sample, individuals were more risk-averse in MC than in HsC and EsC. Moreover, a payoff increase produced a shift toward more risk-averse behaviours in MC, but not in HsC and EsC, where we found an opposite trend suggesting a more risk-loving behaviour. Finally, we found that healthcare workers were significantly less risk-averse compared to non-healthcare workers in EsC, but not in MC and HsC. These findings provided evidence of the possible effects of Covid-19 outbreak on risk-taking aptitudes. The negative impact on human choices and, consequently, on the whole world economy of this catastrophic life event must not be underestimated.
Covid-19 大流行在全球范围内造成了悲惨的影响。威胁生命和充满压力的事件的第一人称体验可以改变个体的风险感知,从而改变风险行为。在这里,我们在封锁阶段调查了 130 名意大利居民的风险承担特征,并比较了医疗保健工作者和非医疗保健工作者。我们专门开发了“Covid-19 风险任务”,包括经典的货币霍尔特-劳里配对彩票任务(货币条件,MC)和两个新的生态条件,探索与不同健康(健康状况条件,HsC)和就业(就业状况条件,EsC)结果相关的 Covid-19 相关风险承担能力。结果表明,在整个样本中,个体在 MC 中的风险厌恶程度高于 HsC 和 EsC。此外,收益增加导致 MC 中的风险厌恶行为向更保守的方向转变,但在 HsC 和 EsC 中没有出现这种情况,在 HsC 和 EsC 中,风险偏好行为呈相反趋势。最后,我们发现,与非医疗保健工作者相比,医疗保健工作者在 EsC 中风险厌恶程度明显较低,但在 MC 和 HsC 中并非如此。这些发现为 Covid-19 爆发对风险承担能力的可能影响提供了证据。这场灾难性的生活事件对人类选择的负面影响,以及对全球经济的影响,绝不能低估。
