I had the immense pleasure last week of listening to George Akerlof give his lecture Phishing for Phools, as part of Duke University’s conference on behavioral matters.  The organizers were from the D-CIDES interdisciplinary program at Duke.  Aside from the unique experience of listening to a Nobel Laureate, I had a personal reason for the gratification.  In my career as an engineering researcher and manager I have been strongly influenced by two non-engineer/scientists.  They are George Akerlof and Adrian Slywotzky (the concept of Value Migration).  I used their work directly in commercial endeavor, although likely in somewhat amateurish fashion.  However, there was nothing amateurish about the bottom line financial results from so doing.  A third influencer, Richard Thaler, I never had the opportunity to reduce to practice, but affects my thinking today in matters such as encouraging energy efficient behavior.

Akerlof was awarded the Nobel Prize for Economics in 2001 (together with Michael Spence and Joseph Stiglitz) essentially for the concept of Information Asymmetry.  It goes something like this.  If I am selling you a used car and provide all information regarding maintenance records and so forth, you will have a sense of the price you are prepared to pay.  If I provide you nothing at all, you are likely to think I am trying to pass off a lemon and will devalue it.  Essentially, the asymmetry of information (seller knows more than the buyer) devalues it in the eyes of the buyer.

Akerlof is generally credited with coining the term ”lemon” for a defective car in his 1970 paper that first described the concept above.  The work is also credited with an impetus to make more information available to car buyers, including the use of Vehicle Identification Numbers (VIN).  Also of note is that this paper, which essentially produced the Nobel Prize, was reputedly rejected by the first three journals to which it was sent!  This is not unlike the reception that Stanley Prusiner got for his paper on prions, infectious proteins that now are the accepted cause of Mad Cow Disease and other cross species infection.  In his case it went beyond rejection to overt denigration, when it did get published.  It too resulted in the Nobel Prize, in this case for Medicine.  This is the curious instance of a Nobel being awarded for the right mechanism for a disease, after another was given for the wrong explanation (Carlton Gadjucek, Nobel Prize for Medicine, 1976) much earlier!

Akerlof defined a phool as a person who is an informed person but still makes an error in judgment.  He explains the recent recession as occurring because phools were misled by highly rated derivatives.  The ratings agencies could not possibly evaluate the mortgages underlying the derivatives but gave them high ratings nevertheless.  He ascribes this to greed.  One wonders whether there was an element of sheer arrogance: their sterling reputations demanded that they have the expertise to do so, and so they did.  He reminded us that economists rely on the belief that people are rational and always act in their own best interests.  But phools may believe they are acting rationally and in fact are not.  He believes that there are folks out there phishing for these phools.  Phishing here is used in the broader context of profiting from the gullible.  Akerlof has a book in the writing entitled Phishing for Phools.

One other paper at the D-CIDES conference was very interesting.  It was by Rick Larrick and co-authors and soon to be published in the Proceedings of the National Academy of Sciences.  We have discussed his other work previously in this blog.  It demonstrated that consumer choice was affected by the labeling information, in this case on compact fluorescent bulbs.  In a laboratory study with real money and technology, conservative and liberal subjects purchased CFLs at the same rate when the economic benefits alone were emphasized, but if a “Protect the Environment” label also appeared with the CFL, moderates and conservatives became significantly less likely to purchase the CFL.  I will post the paper when it is published.  You may remember the Cialdini experiment from a previous blog post of mine.  One wonders whether a segmentation of the subjects may have yielded different results.

The original work by Richard Thaler and Laureate Daniel Kahneman is now being built upon by a number of people, chipping away at this original belief by economists, that people act rationally and in their own best interests.  Duke’s Dan Ariely has a body of work here.  The social science of why people make the decisions they do will be crucial to the adoption of environmentally responsible practices.  This will run the gamut from using less energy for the same level of gratification to the substitution of oil derivatives with more benign alternatives.

A Sustainable Energy Future Will Require Changes in Public Behavior

At a recent meeting at Duke University, President Brodhead was asked about how they prepared students for the real world.  He responded to this softball question in a conventional manner and then ended with a statement of belief in “a contagion of good example.”  Having delivered this almost sotto voce, he then left with no further explanation.  I took him to mean that the Duke community, by its actions, instilled lasting values in departing students.

Although I was willing to give him credit for this nice turn of phrase, I looked it up.  The earliest reference is in Luke where the belief is stated that the contagion of good example is “the best means for inculcating virtue.”  Jesus is believed to have used this in his method of teaching.  The theologian philosopher George Berkeley is quoted as “neighbor will emulate neighbor and the contagion of good example will spread.” This last brings us closest to the situation with green behavior today.

A number of offerings can be expected in the arena of green energy.  Examples would be electricity from renewable sources, car variants such as hybrids, natural gas and electricity powered vehicles, and smart meters in homes, to name a few.  These involve making choices.  Innovators of technology know that the barrier to wide-scale adoption is particularly high when it involves substitution of something familiar. Research in the motivation of early buyers of hybrid electric vehicles showed a disposition to be being “seen as green.” This is close to Berkeley’s neighbors emulating neighbors.  But we all know that early adopters are not necessarily representative of the general population.  Widespread adoption will require a viral spread of beliefs.  This is why the word “contagion” is so appealing in its very unusual use in a positive context.

Robert Cialdini and co-workers at Arizona State University conducted an interesting set of experiments in Phoenix hotels.  One set of guest bathrooms had “re-use towels to save the environment” type placards, as we have all seen ourselves.  In another set of rooms, the placards read that the majority of guests in that very room had re-used their towels.  The incidence of compliance in these latter rooms was 33% greater than in the control set.  Is this an incidence of at least a minor infection of good example?

Energy efficiency is possibly the most powerful weapon in the clean energy arsenal.  This is because no matter how dirty the energy source, using less is a net positive.  Some approaches will be transparent to the public, such as the sub-one watt standby power standard being proposed for household appliances.  However, the choice to keep each one of these plugged in even when not in active use is a conscious one, at least for power hogs such as phone chargers and printers.  Studies have shown that standby power accounts for between 7 – 10% of total household consumption.  To be perfectly clear, this power is  simply enabling a convenience feature, and therefore amenable to behavior modification.  Technology can and will address this issue.  But low power devices will only get you so far.  Can people be pushed in that direction without the compulsion of laws?  Richard H. Thaler and Cass R. Sunstein suggests that this is possible, in their influential work Libertarian Paternalism.  Their concept is further elucidated in their book Nudge.

The Smart Grid is essential to support diurnal sources of electricity such as solar and wind.  It is also needed to assure the proper implementation of electric vehicles.  An aspect of the Smart Grid is smart meters in homes.  These will provide homeowners with considerable data on their energy usage and offer the opportunity for more efficient use.  Time of day pricing will help.  But ultimately, the concepts flowing out of Cialdini’s study cited above are likely to play a role in influencing behavior.  Neighbors emulating neighbors may be literal in this case.
