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 …
The Power Of Stereotyping And Confirmation Bias To Overwhelm Accurate Assessment: The Case Of Economics, Gender, And Risk Aversion, Julie A. Nelson
The Power Of Stereotyping And Confirmation Bias To Overwhelm Accurate Assessment: The Case Of Economics, Gender, And Risk Aversion, Julie A. Nelson
Julie A. Nelson
Behavioral research has revealed how normal human cognitive processes can tend to lead us astray. But do these affect economic researchers, ourselves? This article explores the consequences of stereotyping and confirmation bias using a sample of published articles from the economics literature on gender and risk aversion. The results demonstrate that the supposedly “robust” claim that “women are more risk averse than men” is far less empirically supported than has been claimed. The questions of how these cognitive biases arise and why they have such power are discussed, and methodological practices that may help to attenuate these biases are outlined.
Poisoning The Well, Or How Economic Theory Damages, Julie A. Nelson
Poisoning The Well, Or How Economic Theory Damages, Julie A. Nelson
Julie A. Nelson
Contemporary mainstream economics has widely “poisoned the well” from which people get their ideas about the relationship between economics and ethics. The image of economic life as inherently characterized by self-interest, utility- and profitmaximization, and mechanical controllability has caused many businesspeople, judges, sociologists, philosophers, policymakers, critics of economics, and the public at large to come to tolerate greed and opportunism, or even to expect or encourage them. This essay raises and discusses a number of counterarguments that might be made to the charge that current dominant professional practice is having negative ethical effects, as well as discussing some examples of …
Economic Writing On The Pressing Problems Of The Day: The Roles Of Moral Intuition And Methodological Confusion, Julie A. Nelson
Economic Writing On The Pressing Problems Of The Day: The Roles Of Moral Intuition And Methodological Confusion, Julie A. Nelson
Julie A. Nelson
Economists are often called on to help address pressing problems of the day, yet many economists are uncomfortable about disclosing the values that they bring to this work. 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. …
