Amazin’ly, having a clue about what happened in the past gives us a clue about what is happening now, what will happen.
So, Trump’s imposing tariffs on all and sundry. Some say he’s playing 4D chess, others that his intellect has been corrupted by that nutter, Peter Navarro. Opinions differ and we’ll leave that there as being opinions differ.
That little bit of history that both of them like to point at. Post US Civil War tariffs rose strongly. Doubled and in some cases more than that. It’s also true that the US economy expanded remarkably in that period. Went from the exploitative frontier (and slave) economy to the world’s richest manufacturing one in fact. So, yay for tariffs, obviously.
Except US trade kept increasing over this period. So, tariffs were not reducing imports. Or rather, the total level of imports did not fall because tariffs even as tariffs obviously had an effect upon limiting imports - without tariffs there would have been more.
So, what happened here? The answer is the ocean going steamship.
Tariffs are only one barrier to trade, one cost of trade. Paperwork is another, local standards a third, the theft by rapacious dockside unions a fourth and, obviously enough, the cost of transport a fifth. And we can go on - the cost of information flow a sixth and soon enough we’ll be Richard Murphy shouting eleventhly.
The ocean going steamship reduced the total costs of trade by more than the tariffs raised it. Therefore trade carried on increasing.
Now forward a century, the 1970s and following. We’re told that there’s been some grand policy turn to free trade. That everyone decided to gut the rich world of real manly jobs and ship them off to sweating coolies who could be paid peanuts. The GATT, WTO, just proof of the contention and look, look, they lowered tariffs!
But the container ship (which did for those rapacious dockside unions in most places other than the US), the jet liner, the telephone and now the internet have lowered all those other costs of trade massively. The total costs of trade have dropped massively whatever we could have, should have, done about tariffs. Global trade was going to expand by multiples whatever GATT or WTO did that is.
Which is why these tariffs now have to be so large and bigly. Because to get back to that 1970s - let alone 1870s - it’s necessary to raise total costs of trade to where they were, not just tariffs.
Now, given that I’ve described Navarro as a nutter it’s clear where my sympathies lie in these matters. But my point here isn’t to be cheerleading - not here it isn’t - for freetrade. Rather, it’s just that detail of why these tariffs have to be so damn high to gain the effect they claim they want. All the other costs of trade have declined so precipitately that tariffs now have to carry far more of the burden of the costs of trade than they used to.
My thinking was that tariffs were all a bit moot when people repaired clothes and had horses and carts.
But even in the UK in the 1970s. Clothes, toys, TVs, cars were generally made here, including many of the components that went into them.
You can’t go back, though. Nostalgia is just a bad thing for policy.
Economic theory talks about "comparative advantage". If country A can make X for half the price in country B and country B can make Y for half the price in country A, A should export X in exchange for Y.
Economists seem to think that "comparative advantage" is an act of God. Sometimes it is, if you want to grow bananas or if a geologist discovers a massive deposit of high-grade ore.
Where manufacturing is concerned, it's a combination of know-how and equipment.
Germany produces desirable cars thanks to a combination of petrol-heads, technical education and investment in machinery. Hence, any government can decide it's going to build up a manufacturing industry by pouring money into education and hardware. It may or may or not succeed - in either case, the result is "unfair" competition. If it does succeed, whole cities are turned into wastelands as the losing industry closes down.
It seems to me, then, that the protectionists are fundamentally correct. Economic theory is too simplistic, and the impact of globalisation on the developed world has been almost entirely negative.
