2D:4D Does Not Predict Economic Preferences: Evidence from a Large, Representative Sample

The digit ratio (2D:4D) is considered a proxy for testosterone exposure in utero, and there has been a recent surge of studies testing whether 2D:4D is associated with economic preferences. Although the results are not conclusive, previous studies have reported statistically significant correlations between 2D:4D and risk taking, altruism, positive reciprocity, negative reciprocity and trust. Many “researcher ...

2D:4D and Self-Employment Using SOEP Data: A Replication Study

The 2D:4D digit ratio, the ratio of the length of the 2nd digit to the length of the 4th digit, is often considered a proxy for testosterone exposure in utero. A recent study by Nicolaou et al. (2018) reported an association between the left-hand 2D:4D and self-employment (in a sample of about 1,000 adults). In this pre-registered study we replicate these results on a new and larger sample of about ...

Risk Attitudes and Digit Ratio (2D:4D): Evidence From Prospect Theory

Prenatal androgens have organizational effects on brain and endocrine system development, which may have a partial impact on economic decisions. Numerous studies have investigated the relationship between prenatal testosterone and financial risk taking, yet results remain inconclusive. We suspect that this is due to difficulty in capturing risk preferences with expected utility based tasks. Prospect ...

Income Inequality and Risk Taking: The Impact of Social Comparison Information

In contrast to the assumptions of standard economic theory, recent experimental evi-dence shows that the income of peers has a systematic impact on observed degrees of risk aversion. This paper reports the findings of two experiments examining the impact of income inequality on risk preferences and whether the knowledge of inequality mediates the decisions. In Experiment 1, participants who were recruited ...
