8 Ideas That Will Teach You to Think Like an Economist

Sound economic thinking is vital for a prosperous future.


Economics is the study of human action—the choices people make in a world of scarcity. Scarcity means that people have unlimited wants but we live in a world of limited resources. Because of this fact people have to make choices, and choices imply trade-offs. The choices people make are influenced by the incentives they face and those incentives are shaped by the institutions—rules of the game—under which people live and interact with others.

The Foundation for Economic Education has published some excellent essays on the economic way of thinking and basic concepts (“The Economic Way of Thinking” by Ronald Nash and “Economics for the Citizen” by Walter E. Williams).

In this essay, I will explain eight ideas and give examples of the economic way of thinking.

We often hear how wonderful certain countries are because they provide “free healthcare” or “free education.” Many will also say “I got it for free” because they didn’t pay with money.

The error lies in not understanding the difference between price and cost. For example, people usually say, “The Starbucks latte cost me five dollars” or, “The movie ticket cost me fifteen dollars.” Cost in economics means what you give up or sacrifice. In these examples, the prices were $5 and $15. But the cost of the latte was perhaps the sandwich one could have purchased instead with that same $5, and the cost of the movie was perhaps the three lattes one could have purchased instead with that same $15.

Labeling healthcare and education “free” is not just wrong—”there’s no such thing as a free lunch”—it’s also misleading. As my former professor Walter E. Williams would say, “Unless you believe in Santa Claus or the Tooth Fairy, the money has to come from somewhere.” You might not get a medical bill in those countries but you have more taken out of your paycheck (i.e., taxes) and you might have to wait much longer to get that test or have that “minor” (from the bureaucrats’ perspective) surgery. You pay with either money or time, but either way, you pay! Taxes are also used to pay for public schools, which is yet another example of how people call something “free” when it is not.

There’s a difference between zero price and zero cost. There could be a zero price ($0), but there’s never a zero cost. Therefore, don’t swear anymore by using the “F” word!

“Actions speak louder than words,” is a well-known idiom. Humans act, and the act of choice tells us something. Consider this example: A person walks into an Apple store and sees the price of the latest iPhone and angrily mumbles, “What a rip off” but still proceeds to purchase that phone.

When one does something voluntarily, it demonstrates their true preference at the time. Assuming that individuals are self-interested and will ex ante (looking forward in time) subjectively weigh the cost and benefit of an action, and, also assuming it’s not a right to have the private property of another (i.e., Apple’s iPhone), then when a person walks into an Apple store and buys the new iPhone, the individual obviously expects to be better off in some way at that moment. To say that Apple “took advantage” of the willing customer would be nonsense since Apple, or any private business, cannot force people to buy their product. It’s one thing to say something, but the proof is in the act of choice.

“Don’t cry over spilt milk” means what’s done is done. The only costs that should come into our decision-making are future opportunity costs. Past costs are “sunk.” The typical example to explain the sunk cost fallacy is the movie example. You spend $15 to see a movie and an hour into this three-hour movie you realize that it’s horrible and will only get worse. However, your feeling is that you should stay and get your money’s worth. That is bad economic thinking. The $15 is gone so don’t lose the next two hours of your valuable time—get up and leave.

Most of us know people who were (are) in a horrible relationship or dating the wrong type of person (perhaps this applies to you). But the feeling of “I’ve already spent two years of my life with this person” can lead to a bad decision. Many end up marrying the person in order to justify the investment of time.

No offense to Beyoncé, but if you like yourself, then perhaps don’t let that person “put a ring on it”! Don’t lose the next two years of precious time. It’s better to be single than in a bad relationship (but that’s for another essay).

The optimal or efficient level of pollution is not zero. The optimal number of traffic deaths or sports injuries also is probably not zero. The optimal number of people getting a virus is not zero. The optimal level of safety is not perfect safety. Does this sound strange or harsh? Well, if you want to do a cross country road trip and not walk or ride a bike, or if you want to enjoy playing or watching sports, and if you want to physically interact with others, then it is clear that the optimal level of pollution, deaths, injuries, and people getting a virus is actually greater than zero. The optimal level of safety is less than perfect safety. Nothing is free including more safety—trade-offs are always involved because there is always an opportunity cost when we do something, even things like travel, play sports, or interact with others.

Incremental decision-making is what economists call thinking at the margin. Marginal means the one additional or extra unit. Every time we make a decision it’s as if we are calculating the marginal benefit (the benefit of one more unit) and the marginal cost (what would be given up to acquire one more unit) of the action. The economic way of thinking says something should be done until the marginal benefit (MB) equals the marginal cost (MC). There’s also a concept known as the law of diminishing marginal utility—each additional unit gives less and less utility or benefit.

We want clean air so that our eyes aren’t irritated when we go outside and our lungs don’t burn when we take a breath. However, if the desire is perfectly clean air this would mean no more cars, no planes, no boats or ships, and no trains (some would actually desire this situation, at least theoretically). This would impose tremendous costs on society.

Let’s look at it another way. If I snapped my fingers and made the Pacific Ocean perfectly clean but then put one drop of oil somewhere in the ocean unbeknownst to everyone else, would it be worth it to spend money, time and other resources to hunt down that one drop of oil? The marginal benefit of finding and removing one drop of oil in the quintillions of gallons of water would be less than the marginal cost. In plain English, it’s not worth it. Again, the optimal level of pollution is some, not zero.

When it comes to studying, practicing a sport or musical instrument, or dating someone before marrying them, you might think, “The more time, the better.” I am a literal person so if I told my students, “The more you study the better,” this would mean they would never eat, drink, sleep, or spend time with family and friends. But common sense says that after studying for a certain amount of time most students will say, “I get it” or simply “time to move on.” Why waste more time studying?

Also, if you are in a place in your life where you are considering marriage, then the point of dating is to acquire information about the other person so that you can make a good decision. Ultimately, you come to a point where you have enough information to propose, accept a proposal, or break up with this person. When I proposed to my wife, I did not have perfect information about her, but my information was good enough. Sure, one more month of dating would have given me some marginal benefit in terms of additional information about her, but I came to a point where I had enough information—where MB=MC.

“Good enough is good enough” is what economists mean by doing something until the marginal benefit equals the marginal cost. The MB=MC rule implies that the “more is better” thinking is not optimal. One aspirin from the bottle can help your headache but it’s dangerous to think, “Well, if one is good, the whole bottle is better.” Yes, your headache will be gone but so will you.

In a standard economics class, students are taught absolute advantage and comparative advantage. The former means being able to produce more than another with the same amount of resources or using fewer resources to produce an output. The latter means being able to do something at a lower opportunity cost than another.

Because there’s always an opportunity cost when doing something, sometimes it is advantageous to pay someone else to do something even if we have the knowledge and skills to do it ourselves. This also has applications to trade policy. Just because the United States (actually individuals in the United States) can produce certain products does not mean we should. It’s ok if not everything we buy says “Made in USA” because if the government tries to “protect American jobs” and begins imposing tariffs and quotas, we are not actually saving American jobs. It’s more correct to say we are saving particular jobs at the expense of other American jobs. Of course, good politics and good economics often go in different directions.

The complaint that businesses can charge “whatever they want” is nonsense. For example, why is it that movie theaters only charge $8 for popcorn and not $8,000 or $8,000,000 if they can supposedly charge whatever they want? There are two sides to a market transaction, and it’s this interaction of sellers and buyers that determines the price. What’s interesting is that many times the same people complaining are the ones making noise eating that popcorn during the movie.

Entrepreneurs become wealthy if they create a product or service that provides value for a large number of people. Unless the entrepreneurs received special privileges from the government, they didn’t forcibly take money from their customers.

The anger directed at “the rich” is based on the fallacy of thinking the economy is a fixed-size pie. In other words, those who criticize the “filthy rich” believe that they took a piece that was too big, leaving less pie for the rest of us regular folks. The reality is that these entrepreneurs baked a bigger pie. They benefited, but so did we!

In a business transaction, exchanges are voluntary, and voluntary trade is a win-win situation. The entrepreneur wins (as well as the employees he or she hires) and the customers win.

Intentions and results are not always the same thing. The economic way of thinking teaches us to consider possible unintended consequences of our own actions or the actions of politicians. Just because something sounds good or feels right does not mean a certain goal will be achieved. In fact, the very problem that is being addressed can become worse.

Sound economic thinking also removes one’s blinders. The effects of a policy on all groups are considered, not just one group. This helps individuals to see through politicians’ claims that a policy will save American jobs when in reality only some special-interest group will benefit at the expense of other Americans. When politicians confiscate money (i.e., taxes) to build sports stadiums using the “it will create jobs” argument, the mistake is to focus on the jobs seen and neglecting the unseen—the opportunity cost of those tax dollars.

There is so much more to say about this subject called economics and there are many more examples of the economic way of thinking that I could have included. Some characterize economics as applied common sense; yet, economics also gives us counterintuitive insights.

This is the power and beauty of economics

Are CEOs Overpaid? by Gary M. Galles

Are corporate managers and CEOs overpaid?

Many politicians rail against “overpaid” corporate managers. But these attacks overlook the issues of risk and uncertainty.

Workers agree to compensation before performing their work. Consequently, their compensation reflects not a known value but their expected value when arrangements are made.

Managers who turn out more productive than expected will have been underpaid, those less productive than expected will have been overpaid. But examples of the latter don’t prove managers are generally overpaid.

As performance reveals productivity, competition will also bid compensation of superior managers up and inferior managers down. And we must consider the present value of that entire stream, not a given year’s results, to evaluate managers’ productivity versus pay.

No manager is always right, but not every mistake is proof that they’re overpaid. They are paid for superior, not flawless, judgment — fewer mistakes, but not no mistakes.

That is another reason top managers of large enterprises will be very highly compensated. A 1% higher probability of being right on a $1 billion bet is very valuable, and even more so for a $10 billion bet. But even the best will err sometimes, so mistakes don’t prove shareholders are overpaying for managerial judgment.

Against Eco-pessimism: Half a Century of False Bad News by Matt Ridley

Pope Francis’s new encyclical on the environment (Laudato Sii) warns of the coming environmental catastrophe (“unprecedented destruction of ecosystems, with serious consequences for all of us”).  It’s the latest entry in a long literary tradition of environmental doomsday warnings.

In contrast, Matt Ridley, bestselling author of GenomeThe Agile Gene, and The Rational Optimist, who also received the 2012 Julian Simon Memorial Award from the Competitive Enterprise Institute, says this outlook has proven wrong time again. This is the full text of his acceptance speech. Video is embedded below.

It is now 32 years, nearly a third of a century, since Julian Simon nailed his theses to the door of the eco-pessimist church by publishing his famous article in Science magazine: “Resources, Population, Environment: An Oversupply of False Bad News.”

It is also 40 years since The Limits to Growth and 50 years since Silent Spring, plenty long enough to reflect on whether the world has conformed to Malthusian pessimism or Simonian optimism.

Before I go on, I want to remind you just how viciously Simon was attacked for saying that he thought the bad news was being exaggerated and the good news downplayed.

Verbally at least Simon’s treatment was every bit as rough as Martin Luther’s. Simon was called an imbecile, a moron, silly, ignorant, a flat-earther, a member of the far right, a Marxist.

“Could the editors have found someone to review Simon’s manuscript who had to take off his shoes to count to 20?” said Paul Ehrlich.

Erhlich together with John Holdren then launched a blistering critique, accusing Simon of lying about electricity prices having fallen. It turned out they were basing their criticism on a typo in a table, as Simon discovered by calling the table’s author. To which Ehrlich replied: “what scientist would phone the author of a standard source to make sure there were no typos in a series of numbers?”

Answer: one who likes to get his facts right.

Yet for all the invective, his critics have never laid a glove on Julian Simon then or later. I cannot think of a single significant fact, data point or even prediction where he was eventually proved badly wrong. There may be a few trivia that went wrong, but the big things are all right. Read that 1980 article again today and you will see what I mean.

I want to draw a few lessons from Julian Simon’s battle with the Malthusian minotaur, and from my own foolhardy decision to follow in his footsteps – and those of Bjorn Lomborg, Ron Bailey, Indur Goklany, Ian Murray, Myron Ebell and others – into the labyrinth a couple of decades later.

Consider the words of the publisher’s summary of The Limits to Growth: “Will this be the world that your grandchildren will thank you for? A world where industrial production has sunk to zero. Where population has suffered a catastrophic decline. Where the air, sea, and land are polluted beyond redemption. Where civilization is a distant memory. This is the world that the computer forecasts.”

Again and again Simon was right and his critics were wrong.

Would it not be nice if just one of those people who called him names piped up and admitted it? We optimists have won every intellectual argument and yet we have made no difference at all. My daughter’s textbooks trot out the same old Malthusian dirge as mine did.

What makes it so hard to get the message across?

I think it boils down to five adjectives: ahistorical, finite, static, vested and complacent. The eco-pessimist view ignores history, misunderstands finiteness, thinks statically, has a vested interest in doom and is complacent about innovation.

People have very short memories. They are not just ignoring, but unaware of, the poor track record of eco-pessimists. For me, the fact that each of the scares I mentioned above was taken very seriously at the time, attracting the solemn endorsement of the great and the good, should prompt real skepticism about global warming claims today.

That’s what motivated me to start asking to see the actual evidence about climate change. When I did so I could not find one piece of data – as opposed to a model – that shows either unprecedented change or change is that is anywhere close to causing real harm.

Yet when I made this point to a climate scientist recently, he promptly and cheerily said that “the fact that people have been wrong before does not make them wrong this time,” as if this somehow settled the matter for good.

Second, it is enormously hard for people to grasp Simon’s argument that “Incredible as it may seem at first, the term ‘finite’ is not only inappropriate but downright misleading in the context of natural resources.”

He went on: “Because we find new lodes, invent better production methods and discover new substitutes, the ultimate constraint upon our capacity to enjoy unlimited raw materials at acceptable prices is knowledge.” This is a profoundly counterintuitive point.

Yet was there ever a better demonstration of this truth than the shale gas revolution? Shale gas was always there; but what made it a resource, as opposed to not a resource, was knowledge – the practical know-how developed by George Mitchell in Texas. This has transformed the energy picture of the world.

Besides, as I have noted elsewhere, it’s the renewable – infinite – resources that have a habit of running out: whales, white pine forests, buffalo. It’s a startling fact, but no non-renewable resource has yet come close to exhaustion, whereas lots of renewable ones have.

And by the way, have you noticed something about fossil fuels – we are the only creatures that use them. What this means is that when you use oil, coal or gas, you are not competing with other species. When you use timber, or crops or tide, or hydro or even wind, you are.

There is absolutely no doubt that the world’s policy of encouraging the use of bio-energy, whether in the form of timber or ethanol, is bad for wildlife – it competes with wildlife for land, or wood or food.

Imagine a world in which we relied on crops and wood for all our energy and then along comes somebody and says here’s this stuff underground that we can use instead, so we don’t have to steal the biosphere’s lunch.

Imagine no more. That’s precisely what did happen in the industrial revolution.

Third, the Malthusian view is fundamentally static. Julian Simon’s view is fundamentally dynamic. Again and again when I argue with greens I find that they simply do not grasp the reflexive nature of the world, the way in which prices cause the substitution of resources or the dynamic properties of ecosystems – the word equilibrium has no place in ecology.

Take malaria. The eco-pessimists insisted until recently that malaria must get worse in a warming 21st century world. But, as Paul Reiter kept telling them to no avail, this is nonsense. Malaria disappeared from North America, Russia and Europe and retreated dramatically in South America, Asia and Africa in the twentieth century even as the world warmed.

That’s not because the world got less congenial to mosquitoes. It’s because we moved indoors and drained the swamps and used DDT and malaria medications and so on. Human beings are a moving target. They adapt.

But, my fourth point, another reason Simon’s argument fell on stony ground is that so many people had and have a vested interest in doom. Though they hate to admit it, the environmental movement and the scientific community are vigorous, healthy, competitive, cut-throat, free markets in which corporate leviathans compete for donations, grants, subsidies and publicity. The best way of getting all three is to sound the alarm. If it bleeds it leads. Good news is no news.

Imagine how much money you would get if you put out an advert saying: “we now think climate change will be mild and slow, none the less please donate”. The sums concerned are truly staggering. Greenpeace and WWF, the General Motors and Exxon of the green movement, between them raise and spend a billion dollars a year globally. WWF spends $68m alone on educational propaganda. Frankly, Julian, Bjorn, Ron, Indur, Ian, Myron and I are spitting in the wind.

Yet, fifth, ironically, a further problem is complacency. The eco-pessimists are the Panglossians these days, for it is they who think the world will be fine without developing new technologies. Let’s not adopt GM food – let’s stick with pesticides.

Was there ever a more complacent doctrine than the precautionary principle: don’t try anything new until you are sure it is safe? As if the world were perfect. It is we eco-optimists, ironically, who are acutely aware of how miserable this world still is and how much better we could make it – indeed how precariously dependent we are on still inventing ever more new technologies.

I had a good example of this recently debating a climate alarmist. He insisted that the risk from increasing carbon dioxide was acute and that therefore we needed to drastically cut our emissions by 90 percent or so. In vain did I try to point out that drastically cutting emissions by 90% might do more harm to the poor and the rain forest than anything the emissions themselves might do. That we are taking chemotherapy for a cold, putting a tourniquet round our neck to stop a nosebleed.

My old employer, the Economist, is fond of a version of Pascal’s wager – namely that however small the risk of catastrophic climate change, the impact could be so huge that almost any cost is worth bearing to avert it. I have been trying to persuade them that the very same logic applies to emissions reduction.

However small is the risk that emissions reduction will lead to planetary devastation, almost any price is worth paying to prevent that, including the tiny risk that carbon emissions will destabilize the climate. Just look at Haiti to understand that getting rid of fossil fuels is a huge environmental risk.

That’s what I mean by complacency: complacently assuming that we can decarbonize the economy without severe ecological harm, complacently assuming that we can shut down world trade without starving the poor, that we can grow organic crops for seven billion people without destroying the rain forest.

Having paid homage to Julian Simon’s ideas, let me end by disagreeing with him on one thing. At least I think I am disagreeing with him, but I may be wrong.

He made the argument, which was extraordinary and repulsive to me when I first heard it as a young and orthodox eco-pessimist, that the more people in the world, the more invention. That people were brains as well as mouths, solutions as well as problems. Or as somebody once put it: why is the birth of a baby a cause for concern, while the birth of a calf is a cause for hope?

Now there is a version of this argument that – for some peculiar reason – is very popular among academics, namely that the more people there are, the greater the chance that one of them will be a genius, a scientific or technological Messiah.

Occasionally, Julian Simon sounds like he is in this camp. And if he were here today, — and by Zeus, I wish he were – I would try to persuade him that this is not the point, that what counts is not how many people there are but how well they are communicating. I would tell him about the new evidence from Paleolithic Tasmania, from Mesolithic Europe from the Neolithic Pacific, and from the internet today, that it’s trade and exchange that breeds innovation, through the meeting and mating of ideas.

That the lonely inspired genius is a myth, promulgated by Nobel prizes and the patent system. This means that stupid people are just as important as clever ones; that the collective intelligence that gives us incredible improvements in living standards depends on people’s ideas meeting and mating, more than on how many people there are. That’s why a little country like Athens or Genoa or Holland can suddenly lead the world. That’s why mobile telephony and the internet has no inventor, not even Al Gore.

Not surprisingly, academics don’t like this argument. They just can’t get their pointy heads around the idea that ordinary people drive innovation just by exchanging and specializing. I am sure Julian Simon got it, but I feel he was still flirting with the outlier theory instead.

The great human adventure has barely begun. The greenest thing we can do is innovate. The most sustainable thing we can do is change. The only limit is knowledge. Thank you Julian Simon for these insights.
