Are Women Really More Risk-Averse Than Men? A Re-Analysis Of The Literature Using Expanded Methods, Julie Nelson
Are Women Really More Risk-Averse Than Men? A Re-Analysis Of The Literature Using Expanded Methods, Julie Nelson
Julie A. Nelson
While a substantial literature in economics and finance has concluded that “women are more risk averse than men,” this conclusion merits investigation. After briefly clarifying the difference between making generalizations about groups, on the one hand, and making valid inferences from samples, on the other, this essay suggests improvements to how economists communicate our research results. Supplementing findings of statistical significance with quantitative measures of both substantive difference (Cohen's d, a measure in common use in non-‐Economics literatures) and of substantive overlap (the Index of Similarity, newly proposed here) adds important nuance to the discussion of sex differences. These measures …

This essay explores how an inadequate understanding of the role of methodology, as related to ethics and human emotions of concern, underlies this reluctance and compromises the quality of economic advice. The tension between caring about the problems, on the one hand, and writing within the existing culture of the discipline, on the other, are illustrated with examples from U.S. policymaking, behavioral economics, and the economics of climate change and global poverty. …
