Once again President Trump’s trade adviser displays his lack of understanding of how nations gain from trade. In an op-ed in today’s Wall Street Journal, Mr. Navarro contends that China’s trade practices victimize the U.S. (“China’s Faux Comparative Advantage,” 4/16/18) In doing so, he makes two errors. First, he is wrong to suggest that trade with China that diverts from the “textbook” model of comparative advantage always generates harm to the U.S.  To be sure, ever since David Ricardo described comparative advantage in terms of relative resource and knowhow endowments, that example has been a staple of textbook discussions of how trade can produce gains.  The gains arise because comparative advantage permits both sides to conserve resources.  Those saved resources can then be deployed in other productive activities, thus increasing national wealth.  This result holds even when one trading partner subsidizes its exports, gives tax preferences to its exporters, or “dumps” goods by selling overseas at a lower price than at home.  Such policies, though harming citizens and taxpayers in the exporting country, conserve resources in the importing country and benefit consumers with lower prices.  Letting Chinese citizens and taxpayers subsidize U.S. steel consumption, for example, means that resources that the U.S. would otherwise have to deploy to making steel can now be deployed elsewhere, i.e., we get cheaper steel and other stuff instead of just steel.  That the Chinese government chooses to harm its own citizens is no reason for the U.S. to retaliate by doing the same to its citizens.

The second error that Mr. Navarro makes is conflating such activities as cyberespionage and intellectual property theft with export subsidies and tax preferences.  Stealing property, whether tangible or intangible, is categorically wrong, and Mr. Navarro is right to call out such illicit activities.  The error lies in failing to distinguish between these harmful Chinese practices and practices that are beneficial to the U.S.  The former of course should be targeted for reprobation and fully proscribed.  The latter should be left alone.  Regrettably, the Trump Administration’s recent trade initiatives toward China, which Mr. Navarro helped to formulate, aim indiscriminately at both the good and the bad.
