As I mentioned in an earlier post, almost all economists are opposed to protectionism. In a survey of 264 AEA economists, 87% opposed tariffs to protect US workers against foreign competition.

(By the way, 58% said they usually vote Democrat and only 23% said they usually vote Republican. Given that economists are overwhelmingly middle-age rich White males—only 12% of tenured faculty economists are women and the median income of economists is over $90,000—that’s saying something. Dare I suggest it’s saying that Democrat economic policy is usually better?)

There are a large number of published research papers showing large positive effects of free trade agreements, such as this paper, and this paper, and this paper, and this paper. It’s hard to find any good papers showing any significant negative effects. This is probably why the consensus is so strong; the empirical evidence is overwhelming.

Yet protectionism is very popular among the general public. The majority of both Democrat and Republican voters believe that free trade agreements have harmed the United States. For decades, protectionism has always been the politically popular answer.

To be fair, it’s actually possible to think that free trade harms the US but still support free trade; actually there are some economists who argue that free trade has harmed the US, but has benefited other countries like China and India so much more that it is worth it, making free trade an act of global altruism and good will (for the opposite view, here’s a pretty good article about how “free trade” in principle is often mercantilism in practice, and by no means altruistic). As Krugman talks about, there is some evidence that income inequality in the First World has been exacerbated by globalization—but it’s clearly not the primary reason for rising inequality.

What’s going on here? Are economists ignoring the negative impacts of free trade because it doesn’t fit their elegant mathematical models? Is the general public ignorant of how trade actually works? Does the way free trade works, or its interaction with human psychology, inherently obscure its benefits while emphasizing its harms?

Yes. All of the above.

One of the central mistakes of neoclassical economics is the tendency to over-aggregate. Instead of looking at the impact on individuals, it’s much easier to look at the impact on aggregated abstractions like trade flows and GDP. To some extent this is inevitable—there are simply too many people in the world to keep track of them all. But we need to be aware of what welose when we aggregate, and we need to test the robustness of our theories by applying different models of aggregation (such as comparing “how does this affect Americans” with “how does this affect the First World middle class”).

It is absolutely unambiguous that free trade increases trade flows and GDP, and for small countries these benefits can be mind-bogglingly huge. A key part of the amazing success story of economic development that is Korea is that they dramatically increased their openness to global trade.

The reason for this is absolutely fundamental to economics, and in grasping it in 1776 Adam Smith basically founded the field: Voluntary trade benefits both parties.

As most economists would put it today, comparative advantage leads to Pareto-improving gains from trade. Or as I’d tend to put it, more succinctly yet just as thoroughly based in modern game theory: Trade is nonzero-sum.

When you sell a product to someone, it is because the money they’re offering you is worth more to you than the product—and because the product is worth more to them than the money. You each lose something you value less and gain something you value more—so you are both better off.

This mutual benefit occurs whether you are individuals, corporations, or nations. It’s a fundamental principle of economics that underlies the operation of markets at every scale.

This is what I think most people don’t understand when they say they want to “stop sending jobs overseas”. If by that all you mean is ensuring that there aren’t incentives to offshore and outsource, that’s quite reasonable. Even some degree of incentive to keep businesses in the US might make sense, to avoid a race-to-the-bottom in global wages. But I get the sense that it is more than this, that people have a general notion that jobs are zero-sum and if we hire a million people in China that means a million people must lose their jobs in the US. This is not simply wrong, it is fundamentally wrong; it misses the entire point of economics. If there is one core principle that defines economics, I think it would be that the universe is nonzero-sum; gains for some can also be gains for others. There is not a fixed amount of stuff in the world that we distribute; we can make more stuff. Handled properly, a trade that results in a million people hired in China can mean an extra million people hired in the US.

Once you introduce a competitive market, things get more complicated, because there aren’t just winners—there are also losers. When you have competitors, someone can buy from them instead of you, and the two of them benefit, but you are harmed. By the standard methods of calculating benefits and harms (which admittedly leave much to be desired), we can show quite clearly that in general, on average, the benefits outweigh the harms.

But of course we don’t live “in general, on average”. Despite the overwhelming, unambiguous benefit to the economy as a whole, there is some evidence that free trade can produce a good deal of harm to specific individuals.

Suppose you live in the US and your job is to assemble iPads. You’re good at it, you like it, it pays pretty well. But now Apple says that they want to “reduce labor costs” (they are in fact doing nothing of the sort; to really reduce labor costs in a deep economic sense you’d have to make work easier, more productive, or more fun—the wage and the cost are fundamentally different things), so they outsource production to Foxconn in China, who pay wages 1/30 of what you were being paid.

The net result of this change to the economy as a whole is almost certainly positive—the price of iPads goes down, we all get to have iPads. (There’s a meme going around claiming that the price of an iPad would be almost $15,000 if it were made in the US; no, it would cost about $1000 even if our productivity were no higher and Apple could keep their current profit margin intact, both of which are clearly overestimates. But since it’s currently selling for about $500, that’s still a big difference.) Apple makes more profits, which is why they did it—and we do have to count that in our GDP. Most importantly, workers in China get employed in safe, high-skill jobs instead of working in coal mines, subsistence farming, or turning to drugs and prostitution. More stuff, more profits, better jobs for some of the world’s poorest workers. These are all good things, and overall they outweigh the harm of you losing your job.

Well, from a global perspective, anyway. I doubt they outweigh the harm from your perspective. You still lost a good job; you’re now unemployed, and may have skills so specific that they can’t be transferred to anything else. You’ll need to retrain, which means going back to school or else finding one of those rare far-sighted companies that actually trains their workers. Since the social welfare system in the US is such a quagmire of nonsensical programs, you may be ineligible for support, or eligible in theory and unable to actually get it in practice. (Recently I got a notice from Medicaid that I need to prove again that my income is sufficiently low. Apparently it’s because I got hired at a temporary web development gig, which paid me a whopping $700 over a few weeks—why, that’s almost the per-capita GDP of Ghana, so clearly I am a high-roller who doesn’t need help affording health insurance. I wonder how much they spend sending out these notices.)

If we had a basic income—I know I harp on this a lot, but seriously, it solves almost every economic problem you can think of—losing your job wouldn’t make you feel so desperate, and owning a share in GDP would mean that the rising tide actually would lift all boats. This might make free trade more popular.

But even with ideal policies (which we certainly do not have), the fact remains that human beings are loss-averse. We care more about losses than we do about gains. The pain you feel from losing $100 is about the same as the joy you feel from gaining $200. The pain you feel from losing your job is about twice as intense as the joy you feel from finding a new one.

Because of loss aversion, the constant churn of innovation and change, the “creative destruction” that Schumpeter considered the defining advantage of capitalism—well, it hurts. The constant change and uncertainty is painful, and we want to run away from it.

But the truth is, we can’t. There’s no way to stop the change in the global economy, and most of our attempts to insulate ourselves from it only end up hurting us more. This, I think, is the fundamental reason why protectionism is popular among the general public but not economists: The general public sees protectionism as a way of holding onto the past, while economists recognize that it is simply a way of damaging the future. That constant churning of people gaining and losing jobs isn’t a bug, it’s a feature—it’s the reason that capitalism is so efficient in the first place.

There are a few ways we can reduce the pain of this churning, but we need to focus on that—reducing the pain—rather than trying to stop the churning itself. We should provide social welfare programs that allow people to survive while they are unemployed. We should use active labor market policies to train new workers and match them with good jobs. We may even want to provide some sort of subsidy or incentive to companies that don’t outsource—a small one, to make sure they don’t do so needlessly, but not a large one, so they’ll still do it when it’s actually necessary.

But the one thing we must not do is stop creating jobs overseas. And yes, that is what we are doing, creating jobs. We are not sending jobs that already exist, we are creating new ones. In the short run we also destroy some jobs here, but if we do it right we can replace them—and usually we do okay.

If we stop creating jobs in India and China and around the world, millions of people will starve.

Yes, it is as stark as that. Millions of lives depend upon continued open trade. We in the United States are a manufacturing, technological and agricultural superpower—we could wall ourselves off from the world and only see a few percentage points shaved off of GDP. But a country like Nicaragua or Ghana or Vietnam doesn’t have that option; if they cut off trade, people start dying.

This is actually the main reason why our trade agreements are often so unfair; we are in by far the stronger bargaining position, so we can make them cut their tariffs on textiles even as we maintain our subsidies on agriculture. We are Mr. Bumble dishing out gruel and they are Oliver Twist begging for another bite.

We can’t afford to stop free trade. We can’t even afford to significantly slow it down. A global economy is the best hope we have for global peace and global prosperity.

That is not to say that we should leave trade completely unregulated; trade policy can and should be used to enforce human rights standards. That enormous asymmetry in bargaining power doesn’t have to be used to maximize profits; it can be used to advance human rights.

This is not as simple as saying we should never trade with nations that have bad human rights records, by the way. First of all that would require we cut off Saudi Arabia and China, which is totally unrealistic and would impoverish millions of people; second it doesn’t actually solve the problem. Instead we should use sanctions, tariffs, and trade agreements to provide incentives to improve human rights, rewarding governments that do and punishing governments that don’t. We could have a sliding tariff that decreases every time you show improvement in human rights standards. Think of it like behavioral reinforcement; reward good behavior and you’ll get more of it.

We do need to have sweatshops—but as Krugman has come around to realizing, we can make sweatshops safer. We can put pressure on other countries to treat their workers better, pay them more—and actually make the global economy more efficient, because right now their wages are held down below the efficient level by the power that corporations wield over them. We should not demand that they pay the same they would here in the First World—that’s totally unrealistic, given the difference in productivity—but we should demand that they pay what their workers actually deserve.

Similar incentives should apply to individual corporations, which these days are as powerful as some governments. For example, as part of a zero-tolerance program against forced labor, any company caught using or outsourcing to forced labor should have its profits garnished for damages and the executives who made the decision imprisoned. Sometimes #Scandinaviaisnotbetter; IKEA was involved in such outsourcing during the Cold War, and it is currently being litigated just how much they knew and what they could have done about it. If they knew and did nothing, some IKEA executive should be going to prison. If that seems extreme, let me remind you what they did: They used slaves.

My standard for penalizing human rights violations, whether by corporations or governments, is basically like this: Follow the decision-making up the chain of command, stopping only when the next-higher executive can clearly show to the preponderance of evidence that they were kept out of the loop. If no executive can provide sufficient evidence, the highest-ranking executive at the time the crime was committed will be held responsible. If you don’t want to be held responsible for crimes committed by people who work for you, it’s your responsibility to bring them to justice. Negligence in oversight will not be exonerating because you didn’t know; it will be incriminating because you should have. When your bank is caught laundering money for terrorists and drug lords, it isn’t enough to have your chief of compliance resign; he should be imprisoned—and if his superiors knew about it, so should they.

In fact maybe the focus should be on corporations, because we have the legal authority to do that. When dealing with other countries, there are United Nations rules and simply the de facto power of large trade flows and national standing armies. With Saudi Arabia or China, there’s a very real chance that they’ll simply tell us where we can shove it; but if we get that same kind of response from HSBC or Goldman Sachs (which, actually, we did), we can start taking out handcuffs (that, we did not do—but I think we should have).

We can also use consumer pressure to change the behavior of corporations, such as Fair Trade. There’s some debate about just how effective these things are, but the comparison that is often made between Fair Trade and tariffs is ridiculous; this is a change in consumer behavior, not a change in government policy. There is absolutely no loss of freedom. Choosing not to buy something does not constitute coercion against someone else. Maybe there are more efficient ways to spend money (like donating it directly to the best global development charities), but if you start going down that road you quickly turn into Peter Singer and start saying that wearing nicer shoes means you’re committing murder. By all means, let’s empirically study different methods of fighting poverty and focus on the ones that work best; but there’s a perverse smugness to criticisms of Fair Trade that says to me this isn’t actually about that at all. Instead, I think most people who criticize Fair Trade don’t support the idea of altruism at all—they’re far-right Randian libertarians who honestly believe that selfishness is the highest form of human morality. (It is in fact the second-lowest, according to Kohlberg.) Maybe it will turn out that Fair Trade is actually ineffective at fighting poverty, but it’s clear that an unregulated free market isn’t good at that either. Those aren’t the only options, and the best way to find out which methods work is to give them a try. Consumer pressure clearly can work in some cases, and it’s a low-cost zero-regulation solution. They say the road to Hell is paved with good intentions—but would you rather we have bad intentions instead?

By these two methods we could send a clear message to multinational corporations that if they want to do business in the US—and trust me, they do—they have to meet certain standards of human rights. This in turn will make those corporations put pressure on their suppliers, all the way down the supply chain, to uphold the standards lest they lose their contracts. With some companies upholding labor standards in Third World countries, others will be forced to, as workers refuse to work for companies that don’t. This could make life better for many millions of people.

But this whole plan only works on one condition: We need to have trade.
