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 …
Not-So-Strong Evidence For Gender Differences In Risk, Julie Nelson
Not-So-Strong Evidence For Gender Differences In Risk, Julie Nelson
Julie A. Nelson
In their article "Strong Evidence for Gender Differences in Risk Taking," Gary Charness and Uri Gneezy (2012) review a number of experimental studies regarding investments in risky assets, and claim that these yield strong evidence that females are more risk averse than males. This study replicates and extends their article, demonstrating that its methods are highly problematic. While the methods used would be appropriate for categorical, individual-‐level differences, the data reviewed are not consistent with such a model. Instead, modest differences (at most) exist only at aggregate levels, such as group means. The evidence in favor of gender difference is …
Ethics, Evidence And International Debt, Julie Nelson
Ethics, Evidence And International Debt, Julie Nelson
Julie A. Nelson
The assumption that contracts are largely impersonal, rational, voluntary agreements drawn up between self-interested individual agents is a convenient fiction, necessary for analysis using conventional economic methods. Papers prepared for a recent conference on ethics and international debt were shaped by just such an assumption. The adequacy of this approach is, however, challenged by evidence about who is affected by international debt, how contracts are actually made and followed, the behavior of actors in financial markets, and the motivations of scholars themselves. This essay uses insights from feminist and relational scholarship from several disciplines to analyze the reasons for this …

Economists, Value Judgments, And Climate Change: A View From Feminist Economics, Julie Nelson
Economists, Value Judgments, And Climate Change: A View From Feminist Economics, Julie Nelson
Julie A. Nelson
A number of recent discussions about ethical issues in climate change, as engaged in by economists, have focused on the value of the parameter representing the rate of time preference within models of optimal growth. This essay examines many economists' antipathy to serious discussion of ethical matters, and suggests that the avoidance of questions of intergenerational equity is related to another set of value judgments concerning the quality and objectivity of economic practice. Using insights from feminist philosophy of science and research on high reliability organizations, this essay argues that a more ethically transparent, real-world-oriented, and flexible economic practice would …
