论文摘要
我们可以通过考虑其进化基础来提高对风险偏好的理解。现有文献集中在两种风险来源上：特殊风险和总风险。我们引入了一种新的风险来源，可遗传的风险，在这种风险中，新生儿的适应性与父母的适应性之间存在正相关。在我们的进化过去，可遗传的风险通常是普遍的，它导致严格的增长率比其他风险来源更高。我们表明，进化过去的遗传风险可能会解释人们今天表现出偏见的趋势。
Our understanding of risk preferences can be sharpened by considering their evolutionary basis. The existing literature has focused on two sources of risk: idiosyncratic risk and aggregate risk. We introduce a new source of risk, heritable risk, in which there is a positive correlation between the fitness of a newborn agent and the fitness of her parent. Heritable risk was plausibly common in our evolutionary past and it leads to a strictly higher growth rate than the other sources of risk. We show that the presence of heritable risk in the evolutionary past may explain the tendency of people to exhibit skewness loving today.
