Are Women Really More Risk-Averse Than Men? A Re-Analysis Of The Literature Using Expanded Methods, Julie Nelson Aug 2013

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 Jan 2013

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 Dec 2012

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.


Ethics And The Economist: What Climate Change Demands Of Us, Julie A. Nelson Dec 2012

Ethics And The Economist: What Climate Change Demands Of Us, Julie A. Nelson

Julie A. Nelson

Climate change is changing not only our physical world, but also our intellectual, social, and moral worlds. We are realizing that our situation is profoundly unsafe, interdependent, and uncertain. What, then, does climate change demand of economists, as human beings and as professionals? A discipline of economics based on Enlightenment notions of mechanism and disembodied rationality is not suited to present problems. This essay suggests three major requirements: first, that we take action; second, that we work together; and third, that we focus on avoiding the worst, rather than obtaining the optimal. The essay concludes with suggestions of specific steps …


Poisoning The Well, Or How Economic Theory Damages, Julie A. Nelson Sep 2012

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 …


Broader Questions And A Bigger Toolbox: A Problem-Centered And Student-Centered Approach To Teaching Pluralist Economics, Julie A. Nelson Nov 2011

Broader Questions And A Bigger Toolbox: A Problem-Centered And Student-Centered Approach To Teaching Pluralist Economics, Julie A. Nelson

Julie A. Nelson

This essay discusses a "broader questions and bigger toolbox" approach to teaching pluralist economics. This approach has three central characteristics. First, economics is defined so as to encompass a broad set of (provisioning) concerns. Second, emphasis is placed on contemporary real-world issues, institutions, and current events, rather than on debates in the history of economic thought. Third, a variety of concepts and theories are introduced, all of which are treated as partial and fallible--useful in some (perhaps very limited) situations while not so useful in others. Possible reasons an instructor might want to adopt this approach, and examples of use …


Economic Writing On The Pressing Problems Of The Day: The Roles Of Moral Intuition And Methodological Confusion, Julie A. Nelson Nov 2010

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. …


Getting Past 'Rational Man/Emotional Woman': Comments On Research Programs In Happiness Economics And Interpersonal Relations, Julie A. Nelson May 2010

Getting Past 'Rational Man/Emotional Woman': Comments On Research Programs In Happiness Economics And Interpersonal Relations, Julie A. Nelson

Julie A. Nelson

Orthodox neoclassical economics portrays reason as far more important than emotion, autonomy as more characteristic of economic life than social connection, and, more generally, things culturally and cognitively associated with masculinity as more central than things associated with femininity. Research from contemporary neuroscience suggests that such biases are related to certain automatic processes in the brain, and feminist scholarship suggests ways of getting beyond them. The “happiness” and “interpersonal relations” economics research programs have made substantial progress in overcoming a number of these biases, bringing into consideration by economists a wide range of phenomena which were previously neglected. Analysis from …


Rationality And Humanity: A View From Feminist Economics, Julie A. Nelson Sep 2009

Rationality And Humanity: A View From Feminist Economics, Julie A. Nelson

Julie A. Nelson

DOES RATIONAL CHOICE THEORY (RCT) HAVE SOMETHING IMPORTANT to contribute to the humanities? Usually the arguments for answering “yes” to this question go something like the following: The application of RCT has proved to be a powerful tool in economics and the social sciences, leading to clear and rigorous insights unattainable from less precise methods. Therefore, by also harnessing this power, the disciplines in the humanities could advance toward becoming more elegant, rational, and forceful in their explorations of human behavior. As an economist, I’d like to address this argument on its home ground. Has the use of RCT advanced …


Teaching Ecological And Feminist Economics In The Principles Course, Julie A. Nelson Jun 2009

Teaching Ecological And Feminist Economics In The Principles Course, Julie A. Nelson

Julie A. Nelson

It can be difficult to incorporate ecological and feminist concerns into introductory courses, when one is also obliged to teach neoclassical analysis. In this essay we briefly describe how one might extend existing “multi-paradigmatic” approaches to feminist and ecological concerns, and then present an new alternative approach that may be more suitable for some students. This “broader questions and bigger toolbox” approach can be applied in both microeconomics and macroeconomics introductory classrooms.


Ethics, Evidence And International Debt, Julie Nelson Jun 2009

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 Apr 2008

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 …
