Irrationality is the real invisible hand
Adam Smith first coined the term “The Invisible Hand” in his important book “The Wealth of Nations.” With this term he was trying to capture the idea that the marketplace would be self-regulating. The basic principle of the invisible hand is that though we may be unaware of it, an unseen hand is constantly prodding us along to act in line with what’s best for the whole economy. This means that when this invisible hand exists, when we all pursue our own interest, we end up promoting the public good, and often more effectively than if we had actually and directly intended to do so. This is a beautiful idea, but the question of course is how closely it represents reality.
In 2008, a massive earthquake reduced the financial world to rubble. Standing in the smoke and ash, Alan Greenspan, the former chairman of the Federal Reserve Bank once hailed as “the greatest banker who ever lived,” confessed to Congress that he was “shocked” that the markets did not operate according to his lifelong expectations. He had “made a mistake in presuming that the self-interest of organizations, specifically banks and others, was such that they were best capable of protecting their own shareholders.”
We are now paying a terrible price for our unblinking faith in the power of the invisible hand.
In my mind this experience has taught us that Adam Smith ‘s version of invisible hand does not exist, but that a different version of the invisible hand that is very real, very active, and very dangerous if we don’t learn to recognize it. Perhaps a more accurate description of the invisible hand is that it represents human irrationality. In terms of irrationality the hand that guides our behavior is clearly invisible — after all recent events have demonstrated that we are largely blinded to the ways rationality plays in our lives and our institutions. Moreover it is also clear that irrationality does shape our behavior in many ways, pushing and prodding us along a path can lead to destruction. Whether we’re procrastinating on our medical check-ups, letting our emotions get the best of us, or letting conflicts of interest and short term time horizon ruin the financial market, irrationality is certainly involved.
In Adam Smith’s world the invisible hand was a wonderful force, and the fact it was invisible made no difference whatsoever. The irrational invisible hand is a different story altogether – here we must identify the ways in which irrationality plays tricks on us and make the invisible hand visible!
Why Bankers Would Rather Work for $0.00 Than $500K
Sometimes asking someone to do something for nothing is more powerful than paying them.
In a research paper entitled “Effort for Payment: A Tale of Two Markets,” James Heyman and I that people are willing to help move a couch or perform an experiment just by being asked. Moreover, these individuals feel good about their “gift”. Most interestingly, the experiments show that contrary to standard economic theory, paying a small incremental incentive does not increase effort, but actually lowers it — because meager compensation profanes the gift effect and disincents the giver.
Bringing money into the relationship takes the giver’s work out of “gift” market, and brings it into the “pay-for-effort” market. When it was done for nothing, the protagonist was a “donor.” When small money was on the table, he or she became an underpaid employee. The easiest way to think about this is to imagine if at the end of Thanksgiving dinner you asked your mother-in-law how much you owed her for cooking such a wonderful meal. Would that increase or decrease her effort the next time you came by? (Assuming, of course, she would still invite back you after such an insult.)
In this financial crisis, there has been much discussion about banker’s pay. We think that if President Obama had asked for a group of bankers to take $0, and paid expenses only, it would have brought the discussion back into the gift economy. $500,000 is just low enough to bruise the banker’s egos (after all, they got used to much higher salaries for a long time, higher salaries we can be pretty certain they feel they deserved), but $0 is something to be proud of! In fact, paying these CEOs nothing might remind them about the responsibility they have to the banks they are leading and to the rest of society. The CEO of AIG Ed Liddy is already only taking a one-dollar salary and donating his time to this worthy effort. But his gift is isolated, a drop in the bucket — not part of an overall “corps” of senior financial executives acting in unison to help fix the mess.
Would the best people be willing to work for free? Not all capable bankers could afford it, but many could. We think there would be many willing to pitch in…if asked in the right way. After all, this gift idea was at the core of John F. Kennedy’s brilliant notion, “Ask not what your country can do for you — ask what you can do for your country.” By eliminating pay altogether, these leaders would be giving the nation the donation of their time and skill, improving their level of motivation. Instead of accusing them of being greedy and self interested, people could see them as important actors playing key roles in the stability of our entire economy. This in turn would probably encourage more bankers to see the power of a collective gift and the joy they could feel in donating something so important.
As it stands now, the many good people who are trying to improve things for little or no pay are isolated, their effort drowned out by the outrage over bonuses and salaries. Hence we have the Congress and President involved in legislating the level of executive compensation all the way down to its structure and timing! Congress should not be mired in the details of compensation design. Not only are they bad at it, but the beleaguered public — whose median household income is less than 1/10th of $500,000 — is watching the pay ping pong with collective disgust. The knee-jerk reaction to create a confiscatory 90% tax on the AIG bonuses makes the conservatives among us think we are killing capitalism itself.
When individuals commit acts of personal generosity, it sparks a gift culture that replenishes a store of trust — a resource as multiplicative as any Keynesian monetary policy. This sharing is not done in a communist, carving-up-the-spoils manner, but rather in the tradition of bravery and sacrifice for our collective benefit. When those in power act within a gift culture guided by a spirit of generosity for common cause, it creates a tangible trust asset that supports the flow of credit, money, and markets. By focusing on limiting executive pay, President Obama did the political equivalent of asking his mother-in-law how much he owed her for Thanksgiving dinner — and moved the discussion away from social responsibility, and into the pay-for-effort market, where the negotiations for spoils now dominate the discourse.
We think our bold young President has to improve his request. A gift culture — created at the top — will benefit all of us; and, strangely, will also help strengthen the rapacious markets where self-interest reigns supreme. The good news is, it’s not too late.

April 15th – Tax day and cheating
Will Rogers once said that “The income tax has made liars out of more Americans than golf” and I worry that he was correct.
When I came to the US I was very excited with the tax system. I thought that as a matter of civic engagement this was wonderful ritual, where once a year citizens reflected on their contribution to the common pool of taxes — both for good and for bad. Thinking about the benefits of taxes but also worrying about the waste and protesting against it. Only later did I realize that the tax code is so complex and annoying that instead of thinking about social issues, taxation, and waste –it is mostly a day of annoyance (in fact more than one day) and rather than promoting civic mindedness it is mostly about tying to find loopholes in the tax code that will decrease our individual payments.
One reason for this is that the tax code is so confusing and ambiguous (is taking your sister for dinner and talking to her about work a legitimate business expense? What if she gives you a good idea that you later use?) that we are drawn to the details of how to fit our particular pattern of expenditures within this messy tax code — and while playing this game we also try to minimize our payment.
So, what do we do to fix this problem? First I think that we need to simplify the tax code to make the process less time consuming, less annoying, and maybe even making it more equitable. Second, I think that we can ask citizens how they want the government to use their tax money. This does not have to be 100% of the tax, and instead the tax forms can ask us how we want to allocate 10% of our taxes between education, clean energy, health, etc. By doing so I think that we can increase the care and scrutiny that should come with tax season and more generally increase civic engagement.
Finally – I cannot post something about taxes without making some comment about how to decrease cheating. My suggestion is to have the first question on the tax form asking us if we want to contribute $25 to a task force to fight cheating and corruption. The people who would say “yes” to this question would have committed themselves, and some money, toward honesty — and it is likely that they would continue behaving more ethically while filling in the rest of the tax form. And for the people who answer “no”? Maybe they should audited.
Happy tax day

How to charge $37.50 for a cup of café latte
Imagine that it is the last day of the month and you have $20 in your checking account. Your $2,000 salary will be automatically deposited into your bank later today. You walk down the street and buy yourself a $2.95 ice cream cone. Later you also buy yourself a copy of Predictably Irrational for $25.95, and an hour later you treat yourself to a $2.50 cup of café latte. You pay for everything with debit card, and you feel good about the day – it is payday, after all.
That night, sometime after midnight, the bank settles your account for the day. Instead of first depositing your salary and then charging you for the three purchases, they do the opposite – qualifying you for an overdraft fee. You would think this would be enough punishment, but the banks are even more nefarious. They use an algorithm that charges you for the most expensive item (the book) first. Boom, you are over your available cash and charged a $35 overdraft fee. The ice cream and the latte come next, each with its own $35 overdraft fee. A split second later, your salary is deposited and you are back in the black – only $105 poorer.
Overdraft plans connected to checking accounts are common at most major financial institutions, and the Center for Responsible Lending estimates that this practice costs consumers about $17.5 billion in fees every year. Given these numbers, it is perhaps not very surprising that most financial institutions currently enroll their account holders into this expensive method of covering overdrafts without the customer’s consent or knowledge and that when consumers try to get out of these programs they find it incredibly difficult. When I called the few banks I have accounts with last week and tried to un-enroll from these programs, the most common response I got was that it was impossible. Similarly, one New Jersey columnist reported that his own daughter was charged a $35 overdraft fee for a debit card purchase of less than $2, even when he had accompanied her to open her account and asked that transactions that would overdraw the account be denied. (Paul Mulshine, ‘Courteous’ bankers in for a rude awakening, The Newark Star-Ledger, June 7, 2007, at 15)
With the current financial challenges, I suspect that the people at the lower Social Economic Status (SES) are carrying a large part of the general financial crisis in terms of jobs and housing, as well as a large part of the overdraft fees related to overdraft protection plans. Given this, it is a good sign that the Feds are finally looking at this issue. The first thing that the policymakers are considering is whether to require banks to let their customers opt-out of the default overdraft system. This sounds like a no-brainer. A far better version of the rule would require banks to obtain explicit permission from their customers before enrolling them in this program, the “opt-in rule”. So when you sign up for a bank account, you are not enrolled in this program unless you decide that you want the bank to approve debit purchases you make even if you have no money in your account. Given what we know about defaults and behavioral economics (that most people adapt the default option as their choice, and they see it as an implicit recommendation), I suspect that with the opt-out requirements, the vast majority of consumers will become part of the program and will keep on paying these high penalties, while the opt-in approach would make consumers much less likely to join these programs. Presumably, the banks know this, which is why they are arguing for the right to put all their customers into this expensive system of overdraft coverage without asking.
But of course, this is just the first step. In addition to the pending Federal Reserve regulatory proposal, Representative Carolyn Maloney (D-NY) has introduced legislation that, in addition to requiring that banks get explicit “opt-in” permission, would require warnings at the checkout counters and ATMs to allow customers to cancel a transaction before incurring a fee. It would also stop banks from clearing transactions from the highest to the lowest in order to increase their fees. These are useful reforms that are much needed to prevent banks from taking advantage of their customers.
The banks of course are very worried about losing this income stream, but I suspect that changing the bankers’ mindset from business as usual to one where they are actually going to start seeking their customers’ trust and products that would actually appeal to their clients is in everyone’s best interest. Adopting such programs might in fact push the banks to further improve their overdraft protection programs so that they are truly valuable for their consumers. For example, banks might start giving consumers better access to competitively priced short- term loans, better connections between saving and checking accounts, or at least they can start alerting consumers using SMS when they are in danger of overdrawing their account. In the meantime, the Federal Reserve Board’s “opt-in” rule would be a step in the right direction.
Buffett and his attempts at self-control
I am teaching today in class about self control problems, and approaches to regain self control. Here is a story of Buffett and his attempts at self-control:
Even the most analytical thinkers are predictably irrational; the really smart ones acknowledge and address their irrationalities. We find a great example in Alice Schroeder’s “The Snowball: Warren Buffett and the Business of Life.”
Warren Buffett is a numbers-driven investor whose life choices and business decisions would make the vulcan Mr. Spock seem over-emotional. A teenage horse handicapper who grew up into a deep reader of Moody’s and Standard and Poor’s reports, Buffett is the archetypal quant: a data-processing, information-consuming, hard-thinking, analytical machine. His ability to outperform the market by basing his decisions on hard data and on an uncanny understanding of business fundamentals earned him the moniker “Oracle of Omaha.”
Buffett’s success as an investor required not only deep analysis of financial documents but also a large measure of self-control to avoid getting caught in market bubbles and panics. Buffett’s rule “buy when everyone else is selling, sell when everyone else is buying” requires enormous self-assurance to execute.
And yet, even the Oracle of Omaha is not immune to the allure of irrational behavior. He is what Behavioral Economists call a sophisticate: someone who understands his irrationality and builds systems to cope with it. (The other types of people are the “rational,” who never deviates from optimal behavior, and the “naif,” who is unaware of his irrationality and therefore doesn’t do anything to address it.)
Uncommon a person as he was, Buffett had a very common concern: he feared gaining too much weight. Rational agents don’t gain weight because they always consider all the possible consequences of all actions. Naifs plan to start their diet tomorrow.
But Buffett — who breakfasted on spoonfuls of Ovaltine — understood his predictable irrationality: people eat without consideration for the long-term effects; that’s why they gain unwanted weight. Being a pragmatic person, he decided to curtail overeating with a commitment device.
He gave unsigned checks for $10,000 to his children, promising to sign them if he was over target weight by a certain date. Many people use commitment devices to try to keep their weight down, but Buffett’s idea had a big flaw: his children, spotting a rare opportunity to get money from the notoriously frugal billionaire, resorted to sabotage. Doughnuts, pizza, and fried food mysteriously appeared whenever Buffett was home.
In the end the incentives worked: even with his children’s sabotage, the Oracle kept his weight down, and his checks went unsigned. But had he been purely rational, no commitment device would have been needed.
