The genetics of entrepreneurial performance
研究对美国自雇同卵和异卵双胞胎样本应用行为遗传学方法，发现遗传因素影响自雇收入，且人格特质与收入的相关性受共同基因影响。
Behavioral genetics techniques were applied to a sample of self-employed monozygotic (MZ) and dizygotic (DZ) twins from the USA to examine whether genetic factors influence entrepreneurial performance. The study found that genetics affects the amount of income earned by self-employed people. In addition, the study found that common genes influenced the phenotypic correlations between three of the ‘big five’ personality characteristics – agreeableness, openness to experience and extraversion – and self-employment income, but due to the small sample size, the confidence intervals were high. The implications of a genetic component to self-employment income for research on entrepreneurship are discussed.
