As always, please explain to me where I’m getting it wrong.
The common argument, repeatedly endlessly by reporters and politicians, is that if we import more than we export then that’s bad. It’s bad for American workers because they’re going to lose their jobs if we don’t buy what they make. It’s bad for our long term prosperity because we’re sending all of our money to foreign countries. And it’s bad because it means we’re losing! We’re being outcompeted by our economic and military rivals, e.g. China.
It’s a pretty compelling argument, on the face of it. But there’s something confusing about the whole thing, something that doesn’t quite add up.
When I buy a shiny new Japanese-built car my dollars go to the manufacturer in Japan, and I get the car. But the manufacturer can’t use my dollars to buy things in Japan; the law says you can only use yen to buy things in Japan. So the manufacturer who built my new car has to either spend those dollars in the US, or trade them to someone else who wants to spend them in the US. Those dollars are claims against goods and services in the US – they have to come back to the US in order to be spent.
So every time I spend a dollar buying some imported good, that dollar goes to the foreign company that sold me their product. But eventually that same dollar comes back to the US to be spent on something here. It HAS to, there’s no other place for it to go. So how can we even have a trade deficit? Every dollar spent by Americans on imports eventually comes back as spending on domestic goods, services … or investment.
Investment is the thing that balances the trade deficit. Investment doesn’t show up in imports and exports (when I buy stock in a business, the business stays where it is), so it isn’t counted when computing the trade deficit. So, the reason that America has had a trade deficit with the rest of the world for decades is because Americans have been buying imports while the rest of the world has been buying ownership in America.
What does it mean that the rest of the world is buying ownership in America? Primarily it means two things: 1) Foreign investment in American companies, and 2) Foreign investment in US Federal debt. The rest of the world wants to invest in America because America is a good bet. American companies are enormously productive, and the American government doesn’t default on its loans.
Is it a bad thing that foreigners have been buying ownership in American business? No! American businesses use that investment to innovate and grow. Is it a bad thing that foreigners own US Federal debt? No! The US Treasury sells bonds according to policies that it believes are in the best interests of the US financial system and economy.
The primary effects of the trade deficit have been that Americans have enjoyed low prices for goods and services of all kinds, and have benefited from high levels of direct foreign investment. The real risk is that one day the trade deficit will go away as investment shifts from the increasingly regulation-bound US, to freer markets.
