This table shows Ordinary Least Squares regressions of the premium a subject was willing to pay to avoid a 50/50 lottery $0/$200 on the 2D:4D digit ratio. Risk aversion is positively correlated with the digit ratio. Heteroschedasticity robust standard errors are reported in brackets.
* Means significantly different from zero at the 10% level (two-tail t test),
** at the 5% level, and
↵*** at the 1% level.
