Although prior research has shown that risk-taking preferences and choices are correlated across many domains, there is a dearth of research investigating whether these correlations are primarily the result of genetic or environmental factors. We examine the extent to which common genetic factors account for the association between general risk-taking preferences and domain-specific risk-taking preferences, and between general risk-taking preferences and risk taking choices in financial investments, stock market participation and business formation. Using data from 1898 monozygotic (MZ) and 1344 same-sex dizygotic (DZ) twins, we find that general risk-taking shares a common genetic component with domain-specific risk-taking preferences and risk-taking choices.

遗传因素对冒险偏好和选择的共同影响

尽管先前的研究表明，冒险偏好和选择在许多领域之间都是相关的，但缺乏研究来研究这些相关性主要是遗传因素还是环境因素的结果。我们研究了通用遗传因素在多大程度上承担了一般风险承担偏好和特定领域的风险承担偏好之间的关联，以及在金融投资，股票市场参与和业务组建中一般风险承担偏好与风险承担选择之间的关联。使用来自1898个单卵（MZ）和1344个同性双卵（DZ）双胞胎的数据，我们发现一般风险承担与特定领域的风险承担偏好和风险承担选择具有共同的遗传成分。
