摘要

We systematically investigate the links between the digit ratio (2D:4D)a biomarker for prenatal testosterone exposureand two measures of individual risk taking: (i) risk preferences (RP) over lotteries with real monetary incentives and (ii) self-reported risk attitude (RA). We find that both the right-hand and the left-hand digit ratio are significantly associated with RP: Subjects with lower digit ratios tend to choose riskier lotteries. Neither digit ratio, however, is associated with self-reported RA.
