It is found that a subordinate position raises discount rates, consistent with the reasoning that the present utility of money is higher for men in this position, and the effect was more pronounced for men with a low 2D:4D.
Digit ratio (2D:4D) and pro-social behavior in economic games: No direct correlation
7 Prenatal exposure to hormones, and to sex hormones in particular, exerts organizational 8 effects on the brain and these have observable behavioral correlates in adult life. There 9 are reasons to
Second-to-Fourth Digit Ratio Has a Non-Monotonic Impact on Altruism
It is suggested that there might be an optimal level of exposure to prenatal sex hormones from social perspective and that subjects' altruism decreases with the distance of their ratio to these proxies.
The presence of aggression cues inverts the relation between digit ratio (2D:4D) and prosocial behaviour in a dictator game.
It turns out that in high 2D:4D people, aggression cues even increase prosocial behaviour, and this relationship inverts after exposure to an aggression cue.
Digit ratio (2D : 4D) and prosocial behaviour in economic games: no direct correlation with generosity, bargaining or trust-related behaviours
It is concluded that there is no direct correlation between 2D : 4D and generosity, bargaining or trust-related behaviours and no differences in behaviour were found according to sex.
Digit ratio (2D:4D) and altruism: evidence from a large, multi-ethnic sample
A large, ethnically diverse sample is considered, and for Caucasian subjects and other main ethnic groups in the authors' sample, a significant positive regression coefficient for the right hand digit ratio and a significant negative coefficient for its squared measure are estimated.
Social status and prenatal testosterone exposure assessed via second-to-fourth digit ratio affect 6–9-year-old children’s prosocial choices
It is found that children behaved prosocial, and that their prosocial tendencies were negatively correlated with prenatal androgen exposure; i.e., children with high 2D:4D ratios (reflecting low prenatal androgens exposure) acted more prosocially than children with low 1D to 4D ratios.
Sex Affects the Relationship Between Third Party Punishment and Cooperation
It is found that men are more prone to engage in 3PP than women, and this sex difference is due to cooperative men being more likely to punish than cooperative women.
The digit ratio ( 2 D : 4 D ) and economic preferences : no robust associations in a sample of 330 women ∗
Many studies report on the association between 2D:4D, a putative marker for prenatal testosterone exposure, and economic preferences. However, most of these studies have limited sample sizes and test

Findings add to evidence that prenatal hormonal factors may be linked to men's sexual orientation as well as ethnic groups, after ethnicity was taken into account.
