在本文中，我们使用经典的双胞胎设计来估计遗传和环境对实验引发的风险和给予偏好的影响。使用行为遗传学的标准方法，我们发现强有力的表面证据表明这些偏好广泛遗传，并且我们的估计表明遗传差异解释了大约百分之二十的个体差异。因此，研究结果揭示了偏好个体差异的一个重要来源，而迄今为止，这一来源在经济学文献中基本上被忽视了。
In this paper, we use the classical twin design to provide estimates of genetic and environmental influences on experimentally elicited preferences for risk and giving. Using standard methods from behavior genetics, we find strong prima facie evidence that these preferences are broadly heritable and our estimates suggest that genetic differences explain approximately twenty percent of individual variation. The results thus shed light on an important source of individual variation in preferences, a source that has hitherto been largely neglected in the economics literature.
