Biology and Selection into Entrepreneurship—The Relevance of Prenatal Testosterone Exposure
研究产前睾酮暴露与创业意图的正向关系，发现这种关系通过一般和特定领域的风险承担（如金融投资和职业选择）中介，使用2D:4D指长比作为标记，并控制性别和父母自雇因素。
This study examines the relationship between prenatal testosterone exposure (PTE) and selection into entrepreneurship. We argue that the relationship between PTE and entrepreneurial intent is positive and mediated by general and domain–specific risk–taking related to financial investment and professional career. Using the second–to–fourth digit ratio (2D:4D) as noninvasive retrospective marker for PTE, we identify two–step mediation effects of PTE on entrepreneurial intent through both general and domain–specific risk–taking. To account for possible socialization–based effects, we control for gender and parental self–employment. Applying ordinary least squares (OLS) regression analyses and structural equation models, we provide empirical evidence for a biological association between 2D:4D and entrepreneurial intent.
