Donald Trump’s flawed theory of trade
Economics may be the dismal science, and economists may be boring, but there really are a few eternal economic truths worthy of inscription in stone.
The quantity of a good demanded declines as its price rises. Bigger economies demand more labor, that is, create more jobs. Economic distortions created by government may bestow benefits upon particular groups, but for the economy as a whole harm the economic interests of both consumers and producers by reducing the size of the aggregate economic basket.
And: Freer trade expands that basket. Trade deficits are irrelevant. Protectionism is likely to be the most costly way to help those harmed by international competition. And imports are the benefit and exports the cost of international transactions.
When we go to the supermarket to buy groceries, the goods that we bring home—the imports—are the benefit of the transaction. The dollars that we give to the supermarket in exchange—dollars that we obtained by working, often at jobs that are thoroughly disagreeable—are the cost of the transaction.
The same principle holds for goods that we import from overseas: The clothing and autos and food and the myriad other things that foreigners sell to us are the benefits of trade transactions. If we could obtain comparable goods at comparable prices domestically, we would do so, and thus avoid the higher transportation costs usually attendant upon international shipments.
Donald Trump has argued repeatedly that “we don’t win any more,” and that we sell “practically nothing” to Japan and others, China and Mexico in particular. Really?
U.S. exports to Japan in 2015 were $62.5 billion; for China and Mexico the respective figures were $116.2 billion and $236.4 billion. For advanced technology products, the respective U.S. export figures were $16.9 billion, $34.2 billion, and $40.3 billion, concentrated heavily in aerospace, information and communications, and electronics, among other sectors.
Now, Mr. Trump has decried bilateral trade deficits (buying more from a given country than they buy from us) continuously. That premise is fundamentally flawed: My wife and I buy all our groceries from the local supermarket, and we sell them nothing. So we have a large “bilateral trade deficit” with them; so what? Moreover, Trump has gone on to describe such deficits as “losses,” rhetoric that is particularly ridiculous: Does he believe that we send dollars to, say, China, and receive nothing in return?
Just as individuals and families must live within their means, whole economies ultimately can consume no more than they produce, because those who sell us the goods and services that we consume continue to insist that they be paid. That is the fundamental reason that Mr. Trump’s policy prescriptions are so perverse: Tariffs and other tools to effect “better trade deals” by definition would increase the cost of aggregate consumption, and so cannot improve economic wellbeing unless one believes that such threats would ease trade restrictions overall.
But it is clear that Mr. Trump and many of his supporters are deeply suspicious of liberalized trade, viewing it, often correctly, as a source of reduced wages and earning potential for many Americans forced to compete with foreign producers operating under conditions of lower costs.
Policies that would increase productivity—a reduction in regulatory burdens, adoption of reforms in the tax system, a stronger emphasis on federalism as opposed to the expansion of federal power—are one part of the answer to the problems created for many by foreign competition. But other policies also are needed to improve the economic prospects of those whose livelihoods are threatened by foreign competition. (As an aside: Who does Mr. Trump think are the beneficiaries of all those inexpensive goods imported from, say, China?)
A sharp increase in the earned income tax credit. A wage subsidy. Retraining subsidies. Etc. Making work pay for all is an essential component of a free trade policy, a reality that Mr. Trump does not understand and that many of my fellow proponents of free trade have forgotten.
