Evolution, heritable risk, and skewness loving
引入一种新的风险类型：可遗传风险，即后代与亲代的适应度正相关，这种风险在演化史上常见且增长率更高，可能解释现代人为何偏好偏度。
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.
