Does Studying Economics Breed Greed?

In 1776, Adam Smith famously wrote: "It is not from the benevolence of the butcher, the brewer, or the baker, that we can expect our dinner, but from their regard to their own interest."

Economists have run with this insight for hundreds of years, and some experts think they've run a bit too far. Robert Frank, an economist at Cornell, believes that his profession is squashing cooperation and generosity. And he believes he has the evidence to prove it. Consider these data points:

Less charitable giving: in the U.S., economics professors gave less money to charity than professors in other fields -- including history, philosophy, education, psychology, sociology, anthropology, literature, physics, chemistry, and biology. More than twice as many economics professors gave zero dollars to charity than professors from the other fields.

More deception for personal gain: economics students in Germany were more likely than students from other majors to recommend an overpriced plumber when they were paid to do it.

Greater acceptance of greed: Economics majors and students who had taken at least three economics courses were more likely than their peers to rate greed as "generally good," "correct," and "moral."

Less concern for fairness: Students were given $10 and had to make a proposal about how to divide the money with a peer. If the peer accepted, they had a deal, but if the peer declined, both sides got nothing. On average, economics students proposed to keep 13 percent more money for themselves than students from other majors.

In another experiment, students received money, and could either keep it or donate it to the common pool, where it would be multiplied and divided equally between all participants. On average, students contributed 49 percent of their money, but economics students contributed only 20 percent. When asked what a "fair" contribution was, the non-economists were clear: 100 percent of them said "half or more" (a full 25 percent said "all"). The economists struggled with this question. Over a third of them refused to answer it or gave unintelligible responses. The researchers wrote that the "meaning of 'fairness'... was somewhat alien for this group."

Hearts of Darkness

But maybe studying economics doesn't change people. It could be self-selection: students who already believe in self-interest are drawn to economics.

There is evidence for selection. In a study of over 28,000 students in Switzerland, 62 percent of economics students gave money at least once to help students in need, compared with 69 percent of non-economics students. These differences were already present before the students took a single economics course: students with lower giving rates were drawn to economics. As freshmen, before their first lectures, 71 percent of the students who chose economics contributed, compared with 75 percent of non-economists.

But this doesn't rule out the possibility that studying economics pushes people further toward the selfish extreme. Along with directly learning about self-interest in the classroom, because selfish people are attracted to economics, students end up surrounded by people who believe in and act on the principle of self-interest. Extensive research shows that when people gather in groups, they develop even more extreme beliefs than where they started. Social psychologists call this group polarization. By spending time with like-minded people, economics students may become convinced that selfishness is widespread and rational -- or at least that giving is rare and foolish.

To figure out whether economics education can shift people in the selfish direction, we need to track beliefs and behaviors over time -- or randomly assign them to economics exposure. Here's what the evidence shows:

1. Altruistic Values Drop Among Economics Majors
At the very beginning of their freshman year, Israeli college students who planned to study economics rated helpfulness, honesty, loyalty, and responsibility as just as important as students who were studying communications, political science, and sociology. But third-year economics students rated these values as significantly less important than first-year economics students.

2. Economics Students Stay Selfish, Even Though Their Peers Become More Cooperative
When faced with choices between cooperating and defecting, overall, 60 percent of economics majors defected, compared with only 39 percent of non-economics majors. For non-economists, 54 percent of freshmen and sophomores defected, while only 40 percent of juniors and seniors did. The economists, on the other hand, did not decrease in defection significantly over time. Roughly 70 percent defected across the board. Non-economists became less selfish as they matured; economists didn't.

3. After Taking Economics, Students Become More Selfish and Expect Worse of Others
Frank and his colleagues studied college students in astronomy, economic game theory, and economic development classes. Self-interest was a fundamental assumption in the game theory class, but had little role in the economic development class. In all three classes, students answered questions about benefiting from a billing error where they received ten computers but only paid for nine and finding a lost envelope with $100. They reported how likely they would be to report the billing error and return the envelope, and predicted the odds that other people would do the same.

When the students answered these questions in September at the start of the semester, the estimates were similar across the three classes. When they answered the questions again in December at the end of the semester, Frank's team tracked how many students decreased their estimates. After taking the game theory course, students came to expect more selfish behavior from others, and they became less willing to report the error and return the envelope themselves.

"The pernicious effects of the self-interest theory have been most disturbing," Frank writes in Passions Within Reason. "By encouraging us to expect the worst in others it brings out the worst in us: dreading the role of the chump, we are often loath to heed our nobler instincts."

4. Just Thinking about Economics Can Make Us Less Caring
Exposure to economic words might be enough to inhibit compassion and concern for others, even among experienced executives. In one experiment, Andy Molinsky, Joshua Margolis, and I recruited presidents, CEOs, partners, VPs, directors, and managers who supervised an average of 140 employees. We randomly assigned them to unscramble 30 sentences, with either neutral phrases like [green tree was a] or economic words like [continues economy growing our].

Then, the executives wrote letters conveying bad news to an employee who was transferred to an undesirable city and disciplining a highly competent employee for being late to meetings because she lacked a car. Independent coders rated their letters for compassion.

Executives who unscrambled sentences with economic words expressed significantly less compassion. There were two factors at play: empathy and unprofessionalism. After thinking about economics, executives felt less empathy -- and even when they did empathize, they worried that expressing concern and offering help would be inappropriate.

Changing Economics and Business Education
As a business school professor, these effects worry me. Economics is taught widely in business schools, providing a foundation for courses in management, finance, and accounting. Business is now the most popular undergraduate major in the U.S., and it's growing in market share. From 1997-1998 to 2007-2008, the number of bachelor's degrees conferred in the U.S. grew by 32 percent. In the same time period, the number of business degrees grew by roughly 45 percent. It's true at the graduate level, too: business degrees are right behind education as the most common graduate degrees conferred in the U.S.

Business economics may be more devastating than other brands. When comparing students in political economics and business economics, economists found that "the willingness to contribute decreases dramatically for business students." This may be why the late Stanford professor Hal Leavitt lamented that business education distorts students into "critters with lopsided brains, icy hearts, and shrunken souls."

If economics can discourage prosocial behavior, what should we do about it? I'm not suggesting that we stop teaching economics. An understanding of economics has vital importance to individuals and society. Instead, I recommend three steps for reducing the odds that economics will corrupt students:

(1) Require economics majors to take courses in behavioral economics, which considers the role of "social preferences" like fairness, altruism, cooperation, and even being rationally altruistic.
(2) Require economics majors to take breadth courses in social sciences like biological anthropology, sociology, and psychology, which place substantial emphasis on how people are concerned about others, not only themselves.
(3) Within economics courses, do a better job defining the principle of self-interest around utility, which involves anything a person values -- including helping others. This might mean covering evidence that natural selection can favor unselfish behavior, and that pure selfishness is less common than being "groupish" (willing to put group interests ahead of their own personal interests) and "otherish" (often motivated to help others and themselves at the same time).

Until then, we may be dooming students and society to a fate foreshadowed by Nobel Prize-winning economist and philosopher Amartya Sen. Calling economists "rational fools," Sen observed: "The purely economic man is indeed close to being a social moron."

State terrorism comes in many forms, but one of its most cruel and revolting expressions is when it is aimed at children. Even though U.S. President Donald Trump backed down in the face of a scathing political and public outcry and ended his administration’s policy of separating migrant children from their parents, make no mistake: His actions were and remain a form of terrorism.

It is now clear that the twenty-first century is ushering in a new world order. As uncertainty and instability associated with that process spread around the globe, the West has responded with either timidity or nostalgia for older forms of nationalism that failed in the past and certainly will not work now. Even to the most inveterate optimist, the G7 summit in Quebec earlier this month was proof that the geopolitical West is breaking up and losing its global significance, and that the great destroyer of that American-created and American-led order is none other than the US president. To be sure, Donald Trump is more a symptom than a cause of the West’s disintegration. But he is accelerating the process dramatically.

Sessions quoted a line written by the apostle Paul to a small community of Christians living in Rome around 55AD to defend the Department of Justice’s approach. He said: "I would cite you to the Apostle Paul and his clear and wise command in Romans 13, to obey the laws of the government because God has ordained them for the purpose of order." Sessions used the Bible because one of the most vocal opponents of the crackdown on asylum cases has been the Catholic Church. It’s no surprise that Sessions appealed to Romans chapter 13 verse 1 in response: not only did he hope to undermine Catholic authority by using the Bible against them, he cited a statement so broad that one might use it to defend anything a government does, good or bad.

Extract: PiS [ the ruling Law and Justice party] has established the most significant addition to the Polish social safety net since 1989: the Family 500+ program. Launched in 2016, Family 500+ embodies the nationalism, traditional family values, and social consciousness that the PiS seeks to promote. The program pays families 500 złoty ($144) per month to provide care for a second or subsequent child...........The program has been enormously popular. Some 2.4 million families took advantage of it in the first two years. The benefit, equivalent to 40% of the minimum wage, has almost wiped out extreme poverty for children in Poland, reducing it by an estimated 70-80%........... Liberal pro-European politicians and policymakers are not convinced. They complain that such a generous family benefit will weaken work incentives and blow up the government budget. But initial evidence suggests that Family 500+ has actually increased economic activity. It has also reversed the post-communist decline in fertility, increased wages (particularly for women), and enabled families to buy school materials, take vacations, buy more clothes for their kids, and rely less on high-priced credit for basic household needs. And, thanks to rapid economic growth, the government deficit has steadily fallen, not grown.

Extract: "While the presidency has grown stronger over the years, during the Trump administration Congress has been timid and subordinate. That is because the leaders of the Republican Party – which controls both the House of Representatives and the Senate – are frightened of Trump’s base. They cannot afford to alienate the roughly 30-35% of Americans who passionately back him, ignore his personal transgressions, tolerate his degradation of the country’s civil discourse, favor his brutal treatment of immigrant families, and don’t mind that he is leaving the US almost friendless in the world."

Has North Korea’s ruler, Kim Jong-un, made a strategic decision to trade away his nuclear program, or is he just engaged in another round of deceptive diplomacy, pretending that he will denuclearize in exchange for material benefits for his impoverished country? This is, perhaps, the key question in the run-up to the summit between Kim and US President Donald Trump in Singapore on June 12. Until then, no one will know the answer, perhaps not even Kim himself.

Roseanne Barr is an American comedian whose fictional TV character of the same name is a working-class Trump supporter. For those who remember the show “All in the Family,” she might be usefully compared to Archie Bunker, the crude proletarian patriarch from Queens, New York. Barr’s show was swiftly canceled late last month by the television network ABC, not for anything her “character” said in her show, but for a tweet in which she described Valerie Jarrett, an African-American former adviser to Barack Obama, as the offspring of the Muslim Brotherhood and “Planet of the Apes.”

Extract from the article: "While the West’s relative decline is almost inevitable, its economic dysfunction is not. Yet pessimism can be self-fulfilling. Why undertake difficult reforms if a dark future seems preordained? As a result, accepting and anxious pessimists tend to elect governments that duck difficult decisions (witness Germany’s grand coalition), while angry pessimists make matters worse (by voting for Donald Trump’s “America First” agenda or for Brexit, for example). It doesn’t have to be this way. As French President Emmanuel Macron has demonstrated, bold leaders can succeed with a message of hope, openness, and inclusion, and by promoting a vision of progress based on credible reforms."

It has been nearly two years since the United Kingdom narrowly voted in favor of leaving the European Union. As the march toward Brexit – formally set for the end of next March – proceeds, fundamental questions about the nature of the future UK-EU relationship remain unanswered. Instead, every time a tough decision must be made in the negotiations in Brussels, British ministers kick the can down the road, or even into the long grass. This is somewhat surprising. Apparently, none of the politicians and newspaper editors who plotted for years to get the UK out of the EU thought much about what would happen if their machinations succeeded.

Discussions are now underway to establish a system of joint deposit insurance for eurozone banks. Proponents of the scheme, with the European Commission and the European Central Bank (ECB) taking the lead, point out that deposit insurance would avert the danger of a run on banks in times of crisis. While this argument is true, critics emphasize the disparity in risks, owing to the high share of bad loans on the balance sheets of banks in some countries. To address this risk disparity and move ahead with the plan, balance sheets will need to be cleaned up before considering the next step. While the share of bad loans for banks in the stable eurozone countries is just 2%, the most recently published International Monetary Fund statistics, from last April, show a share of 11% for Ireland, 16% for Italy, 40% for Cyprus, and 46% for Greece.

Trump’s decision cannot be justified by any breach of the agreement on Iran’s part. It is, rather, a return to the old, largely unsuccessful US policy of confrontation with Iran. The only difference this time is that the Trump administration seems determined to go to the brink of war – or even beyond – to get its way. If the administration has any plans for keeping Iran’s nuclear program in check in the absence of the nuclear deal, then it is keeping them a secret. Judging by some of the administration’s rhetoric, it would appear that airstrikes against Iran’s nuclear facilities are on the table. But bombing would only delay Iran’s nuclear program, not stop it. Would Trump then consider a massive ground war to occupy the country and topple the regime? We know all too well how that strategy worked the last time it was tried.

The good news is that the United States and China appear to have backed away from the precipice of a trade war. While vague in detail, a May 19 agreement defuses tension and commits to further negotiation.
