That Thick Glass Ceiling and the role of risk aversion, competition aversion, and cooperation

There’s a short summation of some of the most relevant economic literature on Gender Differences at VOXEU.  Strict micro theory labor models have a difficult time dealing with any form of discrimination because they are based on labor getting paid on its marginal productivity.  Any feature that doesn’t influence production doesn’t really factor neatly in to this particular view of the labor market. This area has been more ripe for study because behavioral economics is now taking into account things beyond the idea that all economic units are rational players.  Theories of rational markets and rational agents do a really bad job of explaining a lot of things including bubbles and busts.  Just like many gender-based disciplines and their studies, the focus usually is on gender specific traits and social learning.  The most germane traits to economic behavior tend to be risk aversion and attitudes towards competition.  Preferences can be modeled through functions and their shape can provide outcomes that vary from the labor market curves of yore.  Many authors find that you have to model female preferences different from male and this contributes to many aspects of what we would call success in business.

Risk taking is generally seen as important to entrepreneurship, investment, and many business undertakings.  It is the focus of a lot of behavior research, some of which can be found in magazines like the Atlanta Parent.

Only recently have economists begun to explore why women and men might have different risk preferences. Broadly speaking, those differences may be due to either nurture, nature, or some combination of the two. For instance, boys are pushed to take risks when participating in risky or competitive sports while girls are often encouraged to remain cautious. Thus, the riskier choices made by males could be due to the nurturing received from parents or peers. Likewise, the disinclination of women to take risks could be the result of parental or peer pressure not to do so.

In recent research (Booth and Nolen 2012), we present a recent experimental study exploring why girls and boys might have different risk preferences. Using adolescent subjects from two distinct environments or ‘cultures’, we examine the effect on risk preferences of two types of environmental influences – randomly assigned experimental peer-groups and educational environment (single-sex or coeducational). The experimental subjects were UK students in years 10 and 11 who were attending either single-sex or coeducational state-funded high schools. We find that the gender composition of the experimental group, as well as the gender mix of the school the student attended, affected decisions on whether or not to enter a real-stakes lottery. But our experiment was conducted at one point in time, and did not track changes over time.

Some important control studies show how women behave in same sex environments.  These studies come from those educational studies that show that many girls do better in girl-only schools because teachers tend to show preferences to boys.  The three authors of this article came up with a way to study this issue in terms of economic decisions.

But our experiment was conducted at one point in time, and did not track changes over time.

The authors wonder if risk taking behavior evolves over time and differently depending on the school and parental environment.   Frequently, a measurement of  risk-taking behavior occurs while playing some kind of gambling game.   The authors set up a study in a co-ed business university as well as a single sex one.  They provided a gambling game to students and tested students at before the start and after the start of the academic year.   They found differences.

We found that, on average, women are significantly less likely to make risky choices than men at both dates. However, after eight weeks in the single-sex class environment – within the larger coeducational milieu – women were significantly more likely to choose the lottery than their counterparts in coeducational groups. No such result was found for men in the single-sex groups. In other words, after eight weeks, the women in the single-sex classes were no more risk averse than men. Moreover, our results were robust to a number of sensitivity checks, including controlling for cognitive and non-cognitive skills (namely IQ and personality type).

The authors argue that this is an important finding.

The findings suggest, first, that a part of the observed gender difference in behaviour under uncertainty found in previous studies might actually reflect social learning rather than inherent gender traits. Of course this is not to say that inherent gender traits do not exist. Rather it suggests that they can be modified across time by the environment in which a woman is placed. Second, the findings are also relevant to the policy debate on the impact of single-sex classes within coeducational schools or colleges on individuals’ behaviour. Whether or not this outcome carries over into other subject areas apart from economics and business remains a topic for future research.

There’s a list of their references as well as some suggestions as where these authors intend to take their research.  Here is one study that’s in one of the more prestigious economic journals. This is a rather ambitious study that looks at risk behavior, bargaining behavior, and view to competition.  I searched out some of the more interesting conclusions including their elucidation of three preferences where men and women differ.

We find that women are indeed more risk averse than men. We find that the social preferences of women are more situationally specific than those of men; women are neither more nor less socially oriented, but their social preferences are more malleable. Finally, we find that women are more averse to competition than are men

These authors look for reasons for the differences and find a variety of things in both the nurture and nature category.  I suppose the important thing is what can we do about this?  Does this mean that women will have to create more opportunities in their own businesses rather than look for success in places where the male risk profiles dominate?  I frankly wondered if this accounted for the incredible gender gap in my field of finance where risk taking and competition are rampant and well-rewarded.  (As you probably can imagine, even the most pathological risk taking generally is rewarded up to a point.)

Anyway, I found this interesting and thought I’d share it with you.


Rick Perry’s Slip is Showing

I’m getting more than a little tired of right wingers who think they can redefine words, rewrite history, and basically lie through their teeth free from accountability.  I agree with Paul Krugman who once said that if reactionaries–not conservatives because conservatives conserve institutions not destroy them–wanted to say the earth wasn’t round that the press would merely print up the headline saying there are differing opinions on the shape of the earth. The Republican Party is continuing to produce flat earthers.  Rick Perry and Michelle Bachmann both appear to live in a world where they feel free to create their own facts and know that very few people will actually call them out on it.   Today, I’m going to correct one of Governor Goodhair’s egregious and pejorative lies.

Perry stuck to a metaphor outlined in his “book” that couldn’t be more wrong during what Republicans called a debate on Monday.  I rather thought it more like the Mad Hatter’s Tea Party but we won’t revisit that.  I’ve done series of articles explaining Social Security in the past–link to first in series here— so I don’t want to revisit the entire system.  The legacy debt, the growing number of retirees, increased life spans, and the shrinking US workforce are all issues but not issues that are insurmountable compared to the benefits derived from the program. What I want to do is tell you why the social security system is not a “Ponzi Scheme” with out reverting to the magical thinking typical of libertarians used in this article printed earlier this week by a rag called Reason that doesn’t seem to know what that word means.

It’s amazing to me that such a popular and successful program is still victim to right wing muddled and nonfactual information.  Social Security is basically longevity insurance and was never designed to replace pensions or even private retirement savings.  All three–albeit pensions are hard to come by these days–are an important part of being able to get through old age.  Social Security works because the majority of people are placed into the system.  This is important for two big economic reasons.  The first is that any risk management (e.g. insurance) program is most cost effective with a huge risk pool. That’s basic insurance theory 101 or spread the risk around common sense theory.

The reason private insurance is so expensive is that unless the company is able to sort out all the ” bad” risks  or charge exorbitantly for it, they will  leave the social costs of the event of that “bad” risk to society (e.g. taxpayers).  This is generally what corporations try to do these days. They won’t cover the overall risk.  They cherry pick the low probably events or low probability people.   Corporations are interested only in profits. They like to privatize profits and force risks and costs onto other folks if they can get away with it.

The second thing is that you get economies of scale (i.e. the process becomes cheapest) when you have a standard contract that’s applied in a standard way to the risk pool.  Having a public insurance program–this would work for a health insurance or flood/hazard insurance–basically lets a country handle its risk in the most cost effective and efficient way.  It takes care of the basic risk problem that would create social costs should the risk not be covered and the event occurs.  A for profit scheme usually covers only people and things with minimal risk.  A basic public offering lets the private sector create specialized programs to fill in gaps without leaving lots of people exposed to the worst risk.

I realize that not a lot of people know a lot about risk and insurance theory because it takes lots of math skills. Economic decisions under risk, information asymmetry, and moral hazard are probably the toughest areas to study other than derivatives which are another form of risk and return management in an advanced degree program.  Hence, most people without advanced degrees don’t even get a whiff of the real stuff. I’m just hoping to give enough of the intuitive stuff here without going into all the models and theorems.

So, any insurance or risk management contract is very different from a Ponzi Scheme. Their pricing is generally based on the level of risk, the chance it will happen to the entity in question, and the potential amount of the loss.  Also, once the event happens, everyone gets paid that experiences the event. How you pay for the plan doesn’t make something a Ponzi Scheme.   Ponzi Schemes are fraudulent by definition and aren’t designed to pay anyone but the originator. They are also not anything resembling a risk management tool.  They are an investment scheme set up to benefit the originators at the cost of new suckers.  They are also voluntary. They prey on people who tend to not know or care to know about the details of a financial scheme and sucker them in by offering them high profits on small initial payments.

Here’s some information on Ponzi Schemes from the FBI. You can read about Bernie Madoff at the site as well as read up on typical red flags for Ponzi schemes.  It’s not rocket science, really.

A Ponzi scheme is an investment fraud that involves the payment of purported returns to existing investors from funds contributed by new investors. Ponzi scheme organizers often solicit new investors by promising to invest funds in opportunities claimed to generate high returns with little or no risk. In many Ponzi schemes, the fraudsters focus on attracting new money to make promised payments to earlier-stage investors and to use for personal expenses, instead of engaging in any legitimate investment activity.

Social Security Trust funds are invested in Treasury Bills. Information on the funds holding is readily available and audited continually by all kinds of interested parties.  Our FICA taxes do not disappear into a rabbit hole.  Also, Social Security has a history of paying benefits to whoever has paid into it, so it has no features at all qualifying it as a Ponzi Scheme.  The deal is that Wall Street wants its hands on that money and the fees resulting from investing it.  Also, libertarians just think that people should be left to the wolves if they’re not clever enough to cover their asses.  Unfortunately, they forget that social costs that implies.  We have a right to protect our country from acts of reckless individuals. That includes corporations that ruin our public resources and individuals whose actions eventually cause costly problems.  Damage done to society is sourced in more things than wars and bar fights.  There are many ways to rob a bank.

So, here’s a Bloomberg article that’s a little more germane to the conversation at hand.

“Ponzi schemes are, by definition, fraud,” said Mitchell Zuckoff, author of “Ponzi’s Scheme: The True Story of a Financial Legend.”

“Social Security is above board,” he added. “We can argue about whether it’s a good system. But you can’t call it a fraud.”

Zuckoff says there’s a big difference between tricking innocents into making doomed investments and a social insurance program that has benefitted millions of Americans. In December 2010, 54 million Americans received either retirement or disability payments under the Social Security program.

The Wall Street Journal does a pretty good job of disabusing Governor Goodhair of his absurd notions of Ponzi schemes if he’d every bother to read it.  I was glad to see that Mittens went after him.  Even Ronald Reagan understood the importance of this form of public insurance.

Strictly speaking, the metaphor is misleading. A Ponzi scheme, named after Boston conman Charles Ponzi, is a fraudulent investment operation. In its essential design it’s a con. Investors don’t earn interest and instead are paid off by other dupes. Because these schemes require an ever-increasing number of new participants to pay off earlier investors, they inevitably collapse.

Social Security isn’t an individual investment plan. It’s a government insurance plan that offers seniors a predictable income. Retirees do indeed depend on future workers to pay their Social Security benefits, though unlike a Ponzi scheme, nobody pretends otherwise. The notion of this kind of inter-generational transfer is baked into the policy.

And unlike regular investments, participants in Social Security don’t own their accounts (although many conservatives would like to see such a change). If you die before you become eligible, your estate doesn’t get the money. If you live longer than average, you get more.

The deal is that fixing the program wouldn’t be difficult.  The idea that people should have a minimum amount of insurance against events in their life isn’t radical at all.  None of this is much different from telling people that drive that they have to have a minimum amount of coverage so that if they hurt some one in an accident they cause, they need to be able to cover the potential damage to the other parties.  Again, when you spread the risk among a huge number of people and make the coverage and the claim procedures standard, the costs and the management become efficient. Also, it’s not really any kind of ‘socialism’ because these are financial contracts.   It’s not like the government is usurping any kind of private property or factor of production.  There’s actually state offered housing liability insurance in Louisiana for people that can’t get coverage from private companies. There’s lots of examples–like FEMA flood insurance–besides social security or medicare.  Like all insurance programs and policies, they just need to be updated ever so often and people need to be reminded that this is basic, vanilla, minimal coverage and its unlikely to be the be-all and end-all to most people’s overall needs.  It just exists to cover society from the worst risks that could eventually create extremely high social costs and havoc when the event occurs and the people impacted aren’t adequately covered.
