Microchips and Potato Chips

Would we Americans be economically better off if the government successfully used “industrial policy” to arrange for us to produce more microchips and fewer potato chips? To many people, this question sounds silly because the answer seems obvious.

But the answer isn’t at all obvious.

There’s little doubt that the US government could use tariffs, import and export quotas, and subsidies to redirect more resources into the domestic production of microchips. And the government might even arrange for a disproportionately large chunk of these redirected resources to come from the snack-food industry. (I here overlook the fact that, in reality, a disproportionately large amount of resources artificially directed into the production of microchips are likely to be drawn, not from the likes of the snack-food industry, but from other high-tech industries.) Yet it’s very unlikely that success at arranging for Americans to produce fewer potato chips and more microchips would yield for Americans net economic benefits.

Production is not consumption. Using tariffs, quotas, and subsidies to arrange for increased domestic production of fewer potato chips and more microchips does not ensure that Americans will be able to afford to use more microchips. If the cost of domestically producing these additional microchips is higher than are the costs that we once incurred to import the same amount of microchips – and that, absent the tariffs, quotas, and subsidies, we’d still incur to import these devices – then these domestically produced microchips become less affordable to us. How, then, can such a result be said to work to our economic advantage?

Having to sacrifice greater amounts of goods X and services Y to acquire some given amount of good Z is the very meaning of good Z becoming less affordable. The fact that we produce more Z doesn’t imply that we thereby can afford to acquire and use more Z. This reality is inescapable whether “Z” stands for potato chips or for microchips.

If you doubt me, ask yourself how affordable would automobiles be to you if you produced your own automobiles rather than bought them from companies such as Toyota or General Motors. How affordable to you would automobiles be if you produced your own cars?

If the goal is to increase Americans’ access to microchips – to improve our ability to acquire and use these high-tech devices – we should acquire them in the least-costly way. And if foreigners are willing to sell microchips to us at prices lower than are the costs that we’d incur to produce these chips domestically, then our access to microchips increases if we import them rather than produce them ourselves.

Wrong!” I hear the anxious protest already. “By importing microchips, we put ourselves at the mercy of foreigners who might in the future restrict our access to this important product.”

It’s possible. But this possibility isn’t as telling as it initially appears to be.

Trade is not a process of unilateral gifting. Trade is exchange. By exporting microchips, foreigners put themselves at the mercy of us Americans who might in the future restrict their access to whatever important products they buy from us with the dollars they earn from their microchip sales. We Americans export lots of petroleum, pharmaceuticals, industrial machines, agricultural products, and higher education – that is, we Americans produce and export many important goods and services that foreigners rely upon. Foreigners’ loss of access to these American exports would weaken their economies. Do we have good enough reason to believe that foreigners will cut off our access to microchips given that they would thereby cut themselves off from access to the likes of petroleum and medicines?

It won’t do, as a reply, to point out correctly that foreign suppliers of microchips can acquire the likes of petroleum, pharmaceuticals, and industrial machines from countries other than America. First, foreigners now acquire from America the goods and services they do because we Americans are the low-cost suppliers of these particular goods and services. It follows that if America no longer exports these goods and services to, say, China, these goods and services can then be acquired by China from countries other than America only at costs higher than are China’s costs of acquiring them from America.

Second and more importantly, just as foreigners could import fewer, say, medicines from America and make up the difference by importing more medicines from other countries, Americans could import fewer microchips from, say, China and make up the difference by importing more microchips from other countries. What holds true for other countries holds true for America, and vice-verse – almost (see below).

“Foreigners” are not a single entity; there’s no country called “Foreign.” Microchips are now produced in Taiwan, Japan, South Korea, Germany, and the Netherlands, among other places. And because in many countries microchips are produced by more than one company, the number of different firms that produce microchips is larger than is even the number of countries in which these mini marvels are produced. So for American-based users of microchips to be held hostage by foreign microchip producers in any economically meaningful manner, several different companies located in several different countries would have to successfully conspire to cut Americans off from microchips. ‘Tis possible, but also ‘tis highly implausible.

In the paragraph before the last I qualified “and vice-versa” with “almost.” There is indeed one way that the US is today unique: The US dollar is the global reserve currency.

One of the ‘goods’ that foreigners wish to acquire from Americans in exchange for the exports they ship here is US dollars. As is true for any and all monies, no one but a pathetic miser wants to acquire dollars as ends in themselves. US dollars are demanded because they can be easily exchanged almost anywhere on earth for petroleum, pharmaceuticals, pinewood, pigs, pretzels, and all other saleable products, most of which are priced on international markets in terms of dollars. Because no other currency is today as widely and as easily accepted around the globe as is the US dollar, people worldwide have an especially high demand for US dollars.

And so while, say, the Chinese might be able, and with little pain, to substitute away from petroleum supplied by America to petroleum supplied by Venezuela or Saudi Arabia, the Chinese cannot so easily substitute away from the US dollar to the bolívar or to the riyal. China’s refusal to sell microchips to Americans would require that China, to get dollars to conduct global commerce, increase exports to countries other than America. But to increase its exports to other countries would also require that China lower the prices it charges for its exports. The bottom line is that Beijing cannot by mandate reduce China’s exports to America without inflicting economic damage on the Chinese people.

Of course, the thugs in power in Beijing, and the craven mandarins below them, might indeed be willing to pay this price to harm America (especially insofar as this price is spread out across China’s billion-plus people). But recognizing that the economic dependence which all free-trading countries come to have on foreign markets is always mutual dependence should at least chip away at the myth that it is easy to repatriate so-called “supply chains,” to use industrial policy to ensure more domestic production of ‘key’ goods, and that we should reduce our production of the likes of potato chips in order to increase our production of the likes of microchips.
