Investigating Gender Differences under Time Pressure in Financial Risk Taking

Area of Science:

• Behavioral Economics
• Neuroeconomics
• Financial Markets

Background:

• Significant gender imbalance exists in financial trading roles.
• Understanding gender differences in financial risk-taking is crucial for market dynamics.

Purpose of the Study:

• Investigate gender disparities in financial risk-taking behavior.
• Examine the impact of time pressure on these differences.
• Explore the role of prenatal testosterone exposure (2D:4D and fWHR) in risk attitudes.

Main Methods:

• Behavioral economics experiments analyzing risky monetary choices.
• Structural modeling with maximum likelihood estimation.
• Analysis under Expected Utility (EU) and Rank-Dependent Utility (RDU) models.
• Measurement of second-to-fourth digit ratio (2D:4D) and face width-to-height ratio (fWHR).

Main Results:

• Men are generally less risk-averse than women.
• The gender gap in risk aversion widens under moderate time pressure.
• Lower 2D:4D ratios and higher fWHR correlate with reduced risk aversion in women (RDU).
• Males with lower 2D:4D ratios show varied risk aversion depending on the model (EU vs. RDU).
• Higher prenatal testosterone indicators in men correlate with increased optimism and overestimation of success probabilities.

Conclusions:

• Gender differences in financial risk-taking are influenced by time pressure and potentially by prenatal testosterone exposure.
• Digit and facial ratios offer insights into the neurobiological underpinnings of financial decision-making.
• Findings contribute to understanding market behavior and gender representation in finance.
