Ethical failures: Where they come from and how to address them



A review of

Gentilin, Dennis. The Origins of Ethical Failures. Lessons for Leaders. A Gower Book. Routledge (2016). ISBN: 978-1-138-69051-6

Ethical failures were in the press big-time in 2017. Prominently, creeps like Harvey Weinstein, James Toback, Bill Cosby, Larry Nassar, etc. were accused of sexual transgressions of various sorts (and in some cases admitted them to varying degrees). The sheer number of accusations leaves little doubt that, in their substance, they are correct. One thing that was truly shocking, on top of the specifics of many of the allegations, was that some of these transgressions went on for literally decades, that many people seem to have known about them for years (if not decades), and that the perpetrators did get away with them for an unconscionably long time. It is clear that organizational failures must have played a major role. This was implicitly acknowledged in the name of  The Royal Commision (RC) into Institutional Responses to Child Sexual Abuse, established under the Gillard government in 2013 and which reported all 17 volumes of its findings on December 15, 2017. The RC also laid out recommendations.

It did not really come as a surprise that once again massive organizational failure, in particular of the Catholic Church, was identified as a major finding. It did not come as a surprise because for years there had been a never-ending stream of trials, not just in Australia, suggesting just that, and providing plenty of evidence that the Catholic Church – in its (continued) belief that it is a law and world unto itself — had engaged for decades in what might generously be called economy with the truth.

Two weeks earlier, after another year of numerous reports of questionable practices, and record profits of the four major banks, the Turnbull government saw itself forced — by its own backbenchers, no less — to announce that it would establish a RC into misconduct in the banking industry. It was a step that Labor and the Greens had urged for more than a year. (The recent draft report of the Productivity Commission has made clear that some such RC is indeed overdue.) The Turnbull government’s acceptance of something that it could not prevent, and its subsequent attempts to undermine the effectiveness of the RC by simultaneously widening its scope and imposing an essentially unrealistic timeline, demonstrates, at the minimum, the kind of myopic opportunism that Australian politics seems drenched in.

Having graduated in 2001, Gentilin became a member of the FX trading desk of the National Australian Bank (NAB), one of the four major banks.  In 2004 that trading desk became involved in a trading scandal that rocked NAB and led, within a couple of weeks, to the resignation of both its chairman and CEO, the reconfiguration of the board of directors, and significant financial and reputational losses. Gentilin was the young trader who blew the whistle. Contrary to many other whistleblowers (who are typically harrassed out of the organizations on which they blew the whistle), he stayed with NAB for more than a decade – as head of the institutional sales team and a member of the corporate strategy team — before he resigned in January 2016 to found Human Systems Advisory, a name meant to be programmatic. The foreword of his book was written by the current chairman of NAB who states: “There are no simple answers in this book. But there are answers. And there are important truths, supported by deep and rigorous analysis. These should be of interest to all corporate leaders, in both executive and non-executive roles.” (p. xvi).   One such truth, says the chairman – apparently quoting Gentilin – is that “leaders must strive to articulate a meaningful social purpose for their organizations that is underpinned by a virtuous set of values.” That’s quite a mouthful, and the impending Royal Commission on the banking system suggests strongly that the major banks (that tried at first to fight off the RC until they realized that fight had been lost) have continuing trouble to understand that particular message, as does the recent draft of the related Productivity Commission report.

Below, I am interested in both the depth and rigor of the analysis and the truths that Gentilin establishes.  I am also interested in the implementability of the measures that he proposes.

In his Introduction, Gentilin states that he draws his evidence from “behavioural business ethics” which he defines as the intersection of business ethics and psychology (p. 5). While he is credited on his website with a degree in psychology, Gentilin makes clear that he wrote this book as a “practitioner” rather than “an academic, a philosopher or an ethicist” (p. 4). He does so in four chapters that explore “The Power of Context”,  “Group Dynamics”,  “Our Flawed Humanity”, and “What We Fail to See”.  A conclusion follows.

Gentilin relies heavily on summaries of articles from psychology that explore human nature and the circumstances under which nice behaviour might turn into, well, not so nice behaviour of different shades. While there is brief perfunctionary nod (p. 3) to the replicability crisis that has afflicted psychology, throughout the book there is little discussion of relevant laboratory design and implementation issues such as incentivisation, experimenter expectancy effects, external validity, and so on (Hertwig & Ortmann 2001; Ortmann 2005). Never mind the fact that much of the evidence on unethical behaviour paraded in this book has been produced with deceptive practices, arguably an unethical practice itself (Ortmann & Hertwig 2002; Hertwig & Ortmann 2008). There is no discussion of statistical issues such (lack of) power computations, p-hacking, publication biases, and what not here either.

Claiming that “explanations of unethical conduct rarely give proper consideration to the system within which people operate … (and) tend to focus on identifying ‘bad apples’ or ‘rogues’” (p. 7), in Chapter 1, Gentilin explores how the environment can impact human (mis)behaviour and, on balance, concludes that “the ‘barrel’ within which the ‘bad apples’ operate must be given as much (if not more) attention as the ‘bad apples’ themselves.” (p. 8). Before he reviews the lessons to be learned from the Stanford Prison Experiment, Gentilin reviews literature on social norms and how they affect behaviour.  The well-known Cialdini et al. littering and Mazar et al. (dis)honesty studies are paraded, as is an interesting lab study by MacNeil & Sherif (1976) in which the authors demonstrate generational transfer of (questionable) practices, and a related field study by Pierce & Snyder (2008). Distinguishing between descriptive (“derived from what is”) and injunctive (“derived from what ought to be”) norms, Gentilin documents cases where unethical descriptive norms tear to smithereens injunctive ones. He relates this to his reading of what led to the FX trading scandal at the NAB: “young people in particular are vulnerable and endorsing immoral social norms … In the FX trading scandal that engulfed the NAB, immoral social norms emerged that promoted excessive risk taking and misstating the true value of the currency options portfolio.” (pp. 18 – 19). This is hardly surprising, and indeed Gentilin mentions the LIBOR rate-fixing scandal and the professional cycling drug-taking as other high-visibility events. He could have also mentioned the lending practices of major US banks before the housing and mortgage crises (e.g., Gjerstad & Smith 2014), the despicable transgressions at Abu Ghraib, or zillions of other real-world examples.  After having reviewed the Stanford Prison experiment in some detail, Gentilin identifies two important take-home lessons from it: first, a specific context “can cause people of sound character to behave in totally uncharacteristic and inappropriate ways.” (p. 24) and, second, the emergence of such contexts is possible only when leaders allow it. Drawing on more experimental evidence (such as Bandura’s children imitating adults’ behaviour experiments), he suggests the obvious parallel for what happened at NAB: “Just as the adults were the role models in Bandura’s experiments, leaders that control the bases of power are the role models in large organizations. For these leaders there will inevitably appear some key moments where, through their actions, choices and decisions, they will send powerful messages that shape the ethical climate for their organizations and types of social norms that emerge.  … how a leader responds in these ‘defining moments’ shapes the ‘character of their companies’.” (p. 30). Only leaders who are veritable role models will be able to prevent formal mechanism being eroded by informal mechanisms that hammer away at them. Again, Gentilin suggests that such failure of leadership is what happened at NAB and at the Barclays Bank during the LIBOR rate-fixing schedule, and for that matter in the phone-hacking scandal that led to the demise of News of the World. Gentilin concludes the chapter with a list of “ten questions for senior leaders within any organization” (pp. 37 – 38). Presumably, these questions are unlikely to be answered in an honest manner where it matters. It is the evidence accumulated in this chapter but also elsewhere (Dana et al. 2007 comes to mind, or Miller & Ross 1976) that suggests that much.

Gentilin starts off Chapter 2 with a Nietzsche quotation that sets the stage: “Madness is the exception in individuals but the rule in groups.” (p. 45). The basic point made is that group membership can reinforce – cue social media echo chambers – the drifting away from injunctive norms to descriptive ones. Writes he: “In my experience at the NAB, dysfunctional group dynamics in the currency options business played a significant role in promoting the emergence and maintenance of immoral social norms and unethical behaviour [such as flagrant and persistent limit breaches or excessive risk taking, AO]”.  To buttress the case, Gentilin presents Milgram’s 1974 obedience studies, as well as Gina Perry’s recent critique of them (Perry 2012) which, in light of considerable supporting evidence of the original studies (e.g., Haslam et al. 2014), he dismissesin their substance. He then highlights what we learn from Milgram’s inclusion of a variation that drew on the group paradigm.  That motivates a discussion of the conformity experiments through which Asch (1956) tried to identify the conditions under which participants would contradict a majority.  In this context, Gentilin also briefly discusses a between-subjects study by Woodzicka & LeFrance (2001) who had a male interviewer ask female applicants inappropriate questions. The basic result was that 6 out of 10 subjects claimed they would object (hypothetically) but none in the control group refused the answer in a “real-life” scenario.  That seems the kind of pattern that allowed the Weinsteins of this world to get their way for too long. Only in the case of Weinstein and similar assholes (here used in the technical sense of Sutton 2007), the stakes were arguably considerably higher. People’s lack of willingness to stand up and be counted is, unfortunately, so widespread that it is well documented and it is a recurrent theme of great movies such as Hidden Figures.  Gentilin makes clear that, based on his experience at NAB, “facing in the fork in the road in a hypothetical scenario is vastly different from facing it in reality.” (p. 67) He also states, “I am personally sceptical of other research into whistleblowing that focuses on ascertaining the types of personality or dispositional characteristics that may predict whether an observer of wrongdoing will take action and report it. …This line of enquiry fails to properly consider the power of the situation.” (p. 67). Gentilin concludes the chapter with another list of “ten questions for senior leaders (and followers) within any organization” (pp. 73). I doubt that these questions will be answered in an honest manner where it matters, for essentially the exact reason that Gentilin has identified in the chapter.

In Chapter 3, Gentilin – notwithstanding his, in my considered opinion, sensible stand on the relative importance of context and dispositional characteristics – dives into “our flawed humanity”. Programmatically, he starts with an epigraph featuring a quotation from Kant, “Out of the crooked timber of humanity, no straight thing has ever been made.” (p. 80).  Gentilin then tries to answer questions such as “Are Humans Self-Interested?”, cursorily sampling evidence from experimental economics, neuroscience, and evolutionary biology. Predictably he concludes that this research shows that “human nature (is) far different from the one suggested by the axiom of self-interest” (p. 86), though he qualifies the statement with the caveat that we are not always altruistic and cooperative.  This alleged “paradigm shift” (p. 87) is, unfortunately, the major bone of contention between those marketing Behavioural Economics (and often shamelessly benefitting from it) and those doing Experimental Economics, and I believe that the social-preferences literature that has created it has as much merits as the IN oxytocin, ego depletion, and power poses research now, for all I can see, thoroughly debunked. Better not plan your life, or organization, on such flimsy evidence. From an evidence point of view, and also a theory point of view (e.g., the important insights stemming from repeated game situations), this chapter is the weakest.  Gentilin’s sampling of the evidence strikes me as scattershot and unsystematic. After discussions of issues such as power and its corrupting influence and fear and awareness of our own mortality that feeds into it, Gentilin concludes the chapter with a list of “eleven questions for senior leaders within any organization” (pp. 118)  I fear, these questions, again, are unlikely to be answered in an honest manner where it matters.

In Chapter 4, Gentilin starts with a quotation from Kahneman’s best-seller Thinking Fast and Slow: “We can be blind to the obvious, and we can also be blind to our blindness.”  This double-whammy – a variant of the Dunning – Krueger effect — is why questions to senior leaders are unlikely to be answered honestly and self-critically.  After a brief mention of another persistent bone of contention – the System 1 / System 2 delineation  – and our alleged propensity to rely too much on automatic system 1 which makes us, presumably, liable to various biases (in this chapter loss aversion, framing, overconfidence, moral disengagement, euphemistic labelling), Gentilin lays out the slippery-slope argument that in his view was at the heart of the events that led to the NAB trading scandal: “The FX trading incident at the NAB classically illustrated the slippery slope in action. Not only did ethical standards erode over time, but the seriousness of the ethical transgressions accelerated … “ (p. 130). Laboratory evidence is provided to  make that point (e.g., the interesting Gino & Bazerman 2008 study) along with field evidence from the NAB case (pp. 131). An intervention discussed here is to give people more time and essentially get them to break out of their System 1 mode: “There are now numerous studies that illustrate how providing a person with more time whenever they are confronted with an ethical dilemma tends to lead to a more virtuous decision being made.” (pp. 146-7). I have serious doubt about the relevance of, say, the Good-Samaritian study mentioned here for real-world decision making and suspect that a theoretical grounding in organizational economics and repeated game theory would really help to address the challenges that organizations and their leaders face.

Gentilin concludes his book with a plea for more (business ethics) education, a call for the installation of Chief Ethics Officers, and more Lessons for Leaders. He wants business schools to challenge their students intellectually, emotionally, and spiritually. That sounds like something straight out of a high-gloss advertisement such schools produce. The reality, however, of Australian business schools (and undoubtedly business schools everywhere) is that they are rarely intellectually demanding. Their inability to challenge their students emotionally and spiritually is shown effectively by their treatment of casuals and staff. What business schools typically do not have are, in particular, truly independent ethics officers, and HR departments, that could hold the feet of currently widely unaccountable senior leadership to the fire. So, while the idea of a Chief Ethics Officer, who has “a genuine ‘seat at the table’” (p. 161), and is independent, able to freely raise matters of concern, and able to freely “speak truth to power” (p. 161), is conceptually on the money, realistically it is very unlikely to be implemented any time soon, as are truly independent HR departments. As to Lessons for Leaders, Gentilin wants them to be virtuous in the sense of having some community-oriented values.  There is a lot of wishful thinking on display here (e.g., that others are willing to take the same risks that he took in 2004) but I think, after everything we learned through the flurry of recent examples mentioned at the beginning of this review, there is not much reason for hope. Even something that should have been uncontroversial, such as the Royal Commission on banking, and the way it came about, demonstrates that common ground is hard to find and cannot be relied on. I fear much harder thinking will be needed to address ethical failures and I fear some strategies will be of the innovative kind provided by the #MeToo campaign that not only has brought down some true monsters but is likely to have changed power and gender relations in the working world irreversibly.

In summary then, Gentilin tackles arguably the most important issue of our times – ethical failures within organizations and for that matter ethical failures more generally. His book is strongest where he illustrates the emergence of his insights with examples from his own NAB 2004 experience. His illustration of various arguments he makes with evidence from behavioural business ethics is wanting. As pointed out above, to his credit Gentilin himself – although unaware of important methodological debates among psychologists as well as between psychologists and economists – grasps intuitively the lack of external validity of some of the evidence that he presents and it is clear that his NAB 2004 experience has been a good guide to identify which laboratory evidence has some external validity, and which does not. I think the book could be considerably improved with a more even-handed and complete assessment of the evidence from psychology and other social sciences (and here in particular economics) as well as an additional focus on incentive-compatible organizational design.  To rely on business ethics education in business schools (whether in Australia or elsewhere) or a sense of community oriented-ness of business leaders is just not going to cut the mustard, as the widely perceived need for the Royal Commission in the banking system demonstrates.

Having recently interacted with NAB, once again, with mortgage related issues, I have no doubt that NAB culture is pervaded with everything but a meaningful social purpose that is underpinned by a virtuous set of values (e.g., the loan officer I dealt with did everything to prevent me from comparison shopping, and essentially gave me misleading information about the rates that I would be getting), and I have little doubt that the same applies to each of the other three major banks. There is a reason why the major banks in Australia have had outsized profits and some of the highest returns on equity in the world. The recent draft of the related Productivity Commission report spells them out.


I appreciate Dennis Gentilin’s comments on a draft of this review.


Review: Tomer’s Advanced Introduction to Behavioral Economics

In the next couple of months I shall, in preparation for an invited longer review essay on recent books on BE, post reviews of individual books such as Tomer’s, Angner’s A Course in Behavioral Economics, Cartwright’s An Introduction to Behavioral Economics, and Dhami’s The Foundations of Behavioral Economic Analysis. Comments are welcome.

Here is the first review, for your entertainment:

Tomer, John F. Advanced Introduction to Behavioral Economics. Elgar (2017). ISBN: 978 1 78471 991 3 (cased), ISBN: 978 1 78471 993 7 (paperback)

Tomer, an Emeritus Professor of Economics at Manhattan College, covers much ground in a fairly superficial manner. We are lectured about the scientific practices of “mainstream economics” (narrow, rigid, intolerant, mechanical, separate, individualistic; see p. 10) and the emergence of behavioral economics (BE). In passing, we hear about different “strands” of BE (chapter 3: “The bounded rationality strand”, chapters  4 and 5: “the psychological economics strand”, chapter 6: “behavioral finance”), “BE, public policy, and nudging” (chapter 7), “law and BE” (chapter 8), “behavioral macroeconomics” (chapter 9), “the empirical methods of BE” (chapter 10), and neuroeconomics (chapter 12).  We are also treated to an answer (I am sure you can guess it) to the question: “Are mainstream economists open-minded toward behavioral economics or do they resist it?” (chapter 11) In chapter 13 the author enlightens us about paths “Toward a more humanistic BE” and in chapter 14 we can read about “Behavioral economic trends”.

Each of these chapters are about 10 – 12 pages long. Along the way we hear about ENE’s  (Early Neoclassical Economics) and NE’s (Neoclassical Economics) “lack of behavioral realism. NE’s lack of connection to other social sciences in particularly regrettable for those who place a high value on a unified social science or at least on having many viable linkages among the different social sciences.” (p. 9) Referring to a decade-old study of his that was published in an inconsequential journal, we learn that “The results for NE (also referred to as mainstream economics) are quite clear. NE is rated high on all six dimensions (narrowness, rigidity, intolerance, mechanicalness, separateness, and individualism,” (p. 12).  After this paper tiger has been successfully constructed, we are told how it is being torn to smithereens: “ In contrast, the eight strands of BE … are in general far less narrow, rigid, intolerant, mechanical, separate, and individualistic than NE. … Overall, there is clear evidence that BE is 1) less positivistic than NE … , 2) distinctively different from NE, and 3) much more integrated with other social science disciplines than NE. In other words, BE is arguably better than NE in the way it conducts its scientific practices.” (p. 12)

This tired rhetorical figure has been used by those marketing BE for a long time. It also shows up regularly in the press (e.g., Elliott 2017 but see Attanasio et al. 2017 or for that matter Ortmann 2012), the related blogosphere, and even literature (Schumacher 2014): while BE is much more realistic and useful, NE is the old staid economics (that has done little for us). In the words of the protagonist of Dear Committee Members, “ … sociology has gone the way of poli-sci and econ, now firmly in the clutches of rabid number crunchers who have abandoned or forgotten the link between their abstruse theoretical  musings and the presence of human beings on the planet’s surface; .. ” (p. 152)

That lack of behavioral realism is, so we learn, addressed by behavioural economists’ wholesale adoption of psychological insights which inevitably “enrich” the dismal models of mainstream  economists.  Ignoring the interesting question what the trade-off is that these richer models come with – in this book this trade-off is never discussed –, there are at least two issues here.

First, and to repeat a theme that I have belabored elsewhere (see also this comment here), there is no such thing as a monolithic body of evidence in psychology that economists could mine to inject more behavioral realism in their allegedly dismal models. The fact is, much of the evidence on heuristics and biases that is being appealed to has been questioned left and right. Every halfway knowledgeable (behavioral) economist will agree that the only interesting question about cognitive biases (such as reference dependence, endowment effects, availability, anchoring & adjustment, and representativeness) is when, and under what circumstances, they exist (if they exist at all).

Second, and more importantly, psychology as a field has, at least since Bem (2011), gone through what many people have called a replicability crisis (e.g., OSC 2015, Spellman 2015, Schimmack 2018) that played at first in blogs and discussion groups such as the Facebook Psychological Methods Discussion Group, but increasingly also in journals and their practices. You would not know that some such upheaval is happening from reading Tomer’s book.

Take, for example, Tomer’s telling discussion of Zak’s oxytocin research in chapter 13. We learn that he is “a well-known economist who appreciates the softer, more intangible side of human behavior” (p. 145) and has shown through his research that “there is a direct link between the amount of oxytocin in humans’ blood and brains and humans’ concerns for each other. … Most importantly, oxytocin fosters trust. Oxytocin surges in a person’s bloodstream when an individual is shown a sign of trust and/or when something engages in a person’s sympathies and they experience empathy. ” (lit cit) Unfortunately, these claims have been thoroughly debunked and even effectively ridiculed in one of John Oliver’s excellent shows. All the literature I know suggests strongly that Intranasal oxytocin has no discernible effect and claims to the contrary are about as much bogus science as claims of ego depletion and the empowering effects of power poses:  what these alleged phenomena reflect is little but shoddy science that people got away with for too long, demonstrating a cavalier attitude to questionable research practices from p-hacking over lack of proper powering up to hiding unsuccessful trials in drawers. You would not know about this crisis if you trusted Tomer who seems completely unaware of these developments that are slowly also starting to be recognized in economics.

Yes, I am not impressed by Tomer’s book. The knowledge laid out in Tomer’s slim volume is severely out of date and unabashedly partisan. According to the December 2017 IDEAS/RePeC data,  there are at least 50,000 research economists out there world-wide and they innovate every day in what is most likely one of the most brutally competitive industries the world has seen. The idea that somewhere someone (“mainstream economics”) has a monopoly on doctrinal truth and can enforce it, shows a stunning cluelessness about the current state of the art (and science) of economics and its sociology.  In his recent presidential address, Alvin E. Roth – an outsider of sorts himself — has argued that economics has been very open to various outsiders and their ideas and practices and you have surely seen that in the emergence of experimental economics and also in some quarters of BE (although BE remains afflicted with many charlatans, often of the non-academic kind that sell BE as panacea to everyone who thinks they can get something for nothing).

I doubt that Tomer’s slim volume is “particularly useful for advanced undergraduate students, graduate students, policymakers, and other professionals who participate economic-related matters.”  (statement on the  back of the book)  In fact, I fear it will promote more sloppy science of the kind that is on display in this book. That kind of sloppy science is also too often on display when you speak with policy makers and Behavioral Insights architects and the like these days.

When all is said and done, it is this kind of sloppiness that undermines trust in the joint enterprise called science.

Thoughts on “Thinking, fast and slow”

I couldn’t resist buying a copy of Daniel Kahneman’s best-seller when returning from holidays. Several friends and colleagues told me it was a great book; it got great reviews; and Kahneman’s journal articles are invariably a good read, so I was curious.

Its general message is simple and intuitively appealing: Kahneman argues that people use two distinct systems to make decisions, a fast one and a slow one. System 1, the fast one, is intuitive and essentially consists of heuristics, such as when we without much thought finish the nursery rhyme ‘Mary had a little…’. The answer ‘lamb’ is what occurs to us from our associative memory. The heuristic to follow that impulse gives the right answer in most cases but can be lead astray by phrases like ‘Ork, ork, ork, soup is eaten with a …’. Less innocuous examples of these heuristics and how they can lead to sub-optimal outcomes are to distrust the unfamiliar, to remember mainly the most intense and the last aspect of an experience (the ‘peak-end rule’), to value something more after possessing it than before possessing it (the ‘endowment effect’) and to judge the probability of an event by how easily examples can come to mind.

System 2, the slow way to make decisions, is more deliberative and involves an individual understanding a situation, involving many different experiences and outside data. System 2 is what many economists would call ‘rational’ whilst System 1 is ‘not so rational’, though Kahneman wants his cake and eat it by saying that System 1 challenges the universality of the rational economic agent model whilst nevertheless not wanting to say that the rational model is wrong. ‘Sort of wrong sometimes’ seems to be his final verdict.

Let me below explore two issues that I have not seen in the reviews of this book. The first is on whether or not his main dichotomy is going to be taken up by economics or social science in the longer-run. The second, related point, is where I think this kind of ‘rationality or not’ debate is leading to. Both issues involve a more careful look at whether the distinction between System 1 and 2 really is all that valid and thus the question of what Kahneman ultimately has achieved, which in turn will center on the usefulness of the rational economic man paradigm.

Knowledge vs Power

From the introduction to Malcolm Gladwell’s splendid new book, What the Dog Saw: And Other Adventures:

The other trick to finding ideas is figuring out the difference between power and knowledge. Of all the people whom you’ll meet in this volume, very few of them are powerful, or even famous. When I said that I’m most interested in minor geniuses, that’s what I meant. … People at the top are self-conscious about what they say (and rightfully so) because they have position and privilege to protect – and self-consciousness is the enemy of ‘interestingness.’

Has anyone else found that the older you get, the less interesting powerful people become? Give me The Book Show over Question Time any day.


My last segment for the year on ABC Radio National’s Life Matters program was talking about Joel Waldfogel’s work on the deadweight cost of Christmas (aka Scroogenomics). The podcast should be here in a few hours.

For the data wonks, I use Waldfogel’s approach of calculating the cost of Christmas as the difference between December retail sales and the average of the abutting November and January. Over recent years, this produces a figure of about $5 billion (2008 was nearly $6 billion, but my guess is that this was stimulus-related). With 21 million Australians, that’s about $250 in Christmas gifts per person. Using surveys, Waldfogel estimates that recipients value gifts at about 82% of the value that they place on their own purchases. In other words, the deadweight cost of Christmas is 18%. For Australia, that suggests our deadweight cost of Christmas is $1 billion for the entire economy, or an average of $50 per person.

What should we do instead? For people you don’t know very well, gift cards beat cash (just make sure the recipient doesn’t lose the card). And for the person who has everything, how about a goat?

Superfreakonomics: The Final Review

I had intended to review Superfreakonomics chapter by chapter but only managed Five, One and Two. Chapter 3 was perhaps the most satisfying of the book dealing with John List’s research on altruism (or that lack of it). It is a bit triumphant but otherwise informative. Chapter 4, in contrast, with pithy and unsatisfying. It was a prelude to Chapter 5 (on global warming) and dealt with how often there are simple solutions so long as you are willing to look for them. They again talk lots about hand washing and they also introduce a plan to rid the US (at least) of category 5 hurricanes. All interesting but it didn’t seem much like economics to me. The book ends by moving to the truly freaky: monkeys are rational economic actors too describing the experiments of Yale’s Keith Chen who managed to introduce currency and prostitution into the monkey economy. Ironically, Levitt and Dubner appear to be saying that for the environment prices don’t matter although for monkeys they’ll do lots in response to small price changes. This highlights what essentially is a lack of a theme throughout the book.

The theme for the book should have been: it is good to look dispassionately at data. And there are ripples at this. But it is obscured by continual digs at government, non-economists and, of course, climate science. Perhaps to be entertaining, it just went too far off message and so the message was lost. Moreover, that entertainment aspect doesn’t look like it is going to translate into book sales. If you are college-aged are you really going to give a book with ‘global cooling’ and ‘prostitution’ in the subtitle to your friends? Last time around it was the rouge economist and that has a certain appeal with its questioning of the unintended side effects of monetary incentives (after all, the Sumo wrestlers cheated because of the gambling). This time around it is more the stereo-typical Chicago-style economist where it is government action that is potentially the evil. And for a book that doubts altruism, hard to say if that says ‘gift me’ this year.
