“Every economic answer is a political question.”
It is entirely possible that the US is tired of carrying most of the burden for the defence of the West and would like a bit of sharing the burden. It might also find some respite for itself in strengthening those parts of its economy which are more closely associated with its defence industries. And it might even wish for some kind of gratitude from others supposedly on its own side in trying to assist the US in resurrecting its strength. And then there are the straightforward economic issues, which are not the same as the political. So let us go to these.
And of course the issue even economically is comparative advantage and not pure let the most efficient producer produce each product. With comparative advantage it is not always the most efficient low-cost producers who produce. If you don’t even understand that, you should keep right out of this debate.
Why encourage free trade:
Why “free trade” is not working for the US:
A regional trading bloc is a group of countries within a geographical region that protect themselves from imports from non-members. Trading blocs are a form of economic integration, and increasingly shape the pattern of world trade. There are several types of trading bloc:
Preferential Trade Area
Preferential Trade Areas (PTAs) exist when countries within a geographical region agree to reduce or eliminate tariff barriers on selected goods imported from other members of the area. This is often the first small step towards the creation of a trading bloc.
Free Trade Area
Free Trade Areas (FTAs) are created when two or more countries in a region agree to reduce or eliminate barriers to trade on all goods coming from other members.
A customs union involves the removal of tariff barriers between members, plus the acceptance of a common (unified) external tariff against non-members. This means that members may negotiate as a single bloc with 3rd parties, such as with other trading blocs, or with the WTO.
World Trade Organisation
There are then the WTO rules of trade engagement which were devised when the US economy was a lot more robust than it now is and when the US was willing to make sacrifices of all kinds to help others withstand the spread of communism. None of this is applicable today. The US is therefore no longer willing to watch others cheat their way into a stronger trade position, at the cost of its own national security and economic strength. Here is part of what the WTO is up to.
1. Most-favoured-nation (MFN): treating other people equally Under the WTO agreements, countries cannot normally discriminate between their trading partners. Grant someone a special favour (such as a lower customs duty rate for one of their products) and you have to do the same for all other WTO members.
2. National treatment: Treating foreigners and locals equally Imported and locally-produced goods should be treated equally — at least after the foreign goods have entered the market. The same should apply to foreign and domestic services, and to foreign and local trademarks, copyrights and patents.
3. Developing countries have transition periods to adjust to the more unfamiliar and, perhaps, difficult WTO provisions — particularly so for the poorest, “least-developed” countries – so these basket case economies are allowed to whittle away at the economic strength of the developed world.
The quote at the top, by the way, is from Joan Robinson, who has quite a lot to say about free trade that ought to be read by the economic illiterates who populate the world, who are now found speaking on behalf of the status quo, as harmful as the status quo is to most of the lower half of the income distribution. Robinson was not just a Keynesian but a Maoist, but she remains one of the clearest and most penetrating economic writers of the twentieth century.
This post on Economics 101 reminds me yet again how useless modern economic theory is at working through almost any economic issue at all. It’s about the theory of comparative advantage, I think, and the role of free trade in creating a high standard of living. But let me go first to this question at Quora: What are 25 economics books that you would recommend (preferably classical and neoclassical)? My answer:
If you are seriously interested in understanding economics you need to understand classical economic theory, the economics of the period from the publication of Adam Smith’s Wealth of Nations in 1776 until the marginal revolution began about a hundred years later in the 1870s. And if you are interested in understanding classical economic theory, you should read the third edition of my own Free Market Economics: an Introduction for the General Reader.
Modern economic theory has fallen into very hard times since its classical period, and is now incapable of explaining almost anything that matters. My FME third edition is entirely supply-side, explaining how classical economists understood the operation of an economy which is how an economy actually does work.
From the marginal revolution with its focus on marginal utility, through to the Keynesian Revolution of the 1930s with its introduction of aggregate demand, economic theory has looked at economies from the demand side. And while it has a superficial appeal, no economy is driven by demand. All economies are driven from its production side. People buy more where more is produced. If you want to understand what allows people to demand, you first have to understand what makes them capable of producing.
I will just add that if you try to read classical theory without some preparation for the changes in the terminology between economics today and economics then, you will miss the point. This is a paper you can find at SSRN which will help you get past what is a quite formidable barrier.
Classical Economics Explained: Understanding Economic Theory Before Keynes
Since the publication of The General Theory, pre-Keynesian economics has been labelled “classical,” but what that classical economics actually consisted of is now virtually an unknown. There is, instead, a straw-man caricature most economists absorb through a form of academic osmosis but which is never specifically taught, not even as part of a course in the history of economics. The paper outlines the crucial features that differentiate modern macroeconomics from classical theory, with the emphasis on what an economist would have understood as The General Theory was being published. Based on the differences outlined, a model of classical economic theory is presented which explains how pre-Keynesian economists understood the operation of the economy, the causes of recession and why a public-spending stimulus was universally rejected by mainstream economists before 1936. The classical model presented is an amalgam of the final edition of John Stuart Mill’s 1848 Principles of Political Economy published in his lifetime and Henry Clay’s influential 1916 Economics: an Introduction for the General Reader, a text which was itself built from the economics of Mill.
Here’s the link to the paper.
As for comparative advantage and free trade, if you’d like a very good explanation of its classical meaning, you won’t do better than my Free Market Economics, an analysis I have not changed a word of since the first edition. It is naturally taken from the economics of John Stuart Mill who had himself taken it from David Ricardo, who wrote it up in 1817. It’s a great first approximation for all those economic types who are actually addicted to mercantilism, whereby economies are driven from the demand side and economies grow by increasing their level of exports. I know, who could believe such a thing, but let us assume just for now that there really are morons who harbour such views. How did Mill and Ricardo explain what was wrong with such notions? By pointing out that the best way to improve one’s standard of living is to produce what one does best and exchange one’s own forms of supply for the goods and services produced by others. You know, goods buy goods. You know, Say’s Law. You know? Perhaps not.
But you know what was also current then? The gold standard. There are many ways this process of comparative advantage breaks down, but with the abandonment of the gold standard and fixed exchange rates, there are all kinds of ways to cheat in foreign trade relations that are not discussed as part of the basic theory. This is the definition of “currency manipulation” found at Google:
It occurs when a government or central bank buys or sells foreign currency in exchange for their own domestic currency, generally with the intention of influencing the exchange rate and trade
“Influencing” as in making one’s own situation better at the expense of someone else. It can be done, and is done. And there’s more. For most economies, a devaluation occurs naturally with deficits but not with the $US which is the world’s reserve currency. And let me also add this, that there is no trade war imaginable unless others decide to retaliate. And why would they if the only damage of increased tariffs in the US is to its own economy? Let the US suffer for its actions, right? Why poke yourself in the eye if they want to poke themselves in the eye?
There is so much more that can be said but will leave it to some other time.
From Forbes, the kind of thing you find in among Chamber of Commerce types: Trump’s Tariffs Are A Reminder He’s Clueless About Trade. Sure he is, and the evidence keeps piling up day by day. If we lived in a crony-capitalist-free world, and no one ever cheated in their trade relations,* maybe such blanket statements would make sense. But truly lacking in any penetration is the manipulation of arithmetical statistical identities as if they were actual theoretical constructs where a change in one variable is the cause of a change in another. In reality, with such identities, these are accounting balancing items which have no effect on actualities in the real world, but are only a record of what took place.
Now here is where the simple analytics of the trade deficit can be used to prove the cluelessness of the Trump trade team on “trade,” of all things, and the utter futility of its policy prescriptions having any impact on America’s aggregate trade deficit. In economics, identities play an important role. These identities are obtained by equating two different breakdowns of a single aggregate. Identities are interesting, and usually important, by definition. In national income accounting, the following identity can be derived. Indeed, it is the key to understanding the trade deficit.
(Imports – Exports ) ≡ (Investment – Savings) + (Government Spending – Taxes)
Given this identify, which must hold, the trade deficit is equal to the excess of private sector investment over savings, plus the excess of government spending over tax revenue. So the counterpart of the trade deficit is the sum of the private sector deficit and the government deficit (federal + state and local). The U.S. trade deficit, therefore, is just the mirror image of what is happening in the U.S. domestic economy. If expenditures in the U.S. exceed the incomes produced in the U.S., which they do, the excess expenditures will be met by an excess of imports over exports (read: a trade deficit).
This is the same as fiddling with Y=C+I+G and pretending that an increase in G can cause an increase in Y. Complete sophistry. There is much more to say about free trade and I have been meaning to say it for a while. This might therefore be what finally stirs me to spell it out in more detail, but this will have to do for now.
* See, for example, Australia takes Canada to WTO over rules on selling wine. My dual nationality obviously makes it impossible for me to see the rights and wrongs of this, but let me say that no Australian will ever understand the liquor laws of Canada, which were introduced as temporary measures during World War I. There’s a lesson in there as well.
