Balanced Trade, Robust Industry, and Rising Productivity: Pick All Three
Professor Dan Drezner is again illustrating how we ended up with a misbegotten consensus on globalization built upon inadequate assumptions and shallow analysis. A couple of weeks ago, we encountered him badly mischaracterizing a study about the supposed value of trade liberalization. Breezing past that issue, he is back now with a more outlandish claim, that: “a world in which ‘trade were balanced, domestic industry robust, and productivity rising’ is a world that not only does not exist, but very likely cannot exist” (emphasis in original).
Cannot exist! In the blackboard model of comparative advantage on which Drezner relies, this is exactly what happens. If it’s not what we should expect, or at least pursue, then which facet would economists concede is not achievable in a well-functioning global economy?
According to Drezner, “The entire point of trade is letting countries specialize in the areas in which they have a comparative advantage in productivity. Any shift toward autarky means a more diversified production portfolio — but also a less productive one.” This may be true in a painfully simplistic, point-in-time, partial-equilibrium analysis. But it is absolutely (and empirically) not true in the long run. As Cesar A. Hildago and Ricardo Hausmann have shown, in fact it is the complexity and diversity of a domestic economy that better predicts its growth over time. Long-time Intel CEO Andy Grove made a related point about innovation, one that Drezner ellipses out of his response to me and then fails to engage, so I will repeat it here:
If profit margins are the problem, we go to work on margins, with exquisite focus. Each company, ruggedly individualistic, does its best to expand efficiently and improve its own profitability. However, our pursuit of our individual businesses, which often involves transferring manufacturing and a great deal of engineering out of the country, has hindered our ability to bring innovations to scale at home. Without scaling, we don’t just lose jobs — we lose our hold on new technologies. Losing the ability to scale will ultimately damage our capacity to innovate.
Further, some industries lend themselves to higher productivity than others, and treating comparative advantage as some exogenous fact to be discovered and complied with can leave your country on the short end of the stick. As I wrote at Law & Liberty:
Economists have long understood that the basic model describes poorly the modern international economy. For example, one crucial driver of comparative advantage is scale. The things which one makes a lot of, one is likely to make more efficiently. Thus, rather than a nation focusing where it has comparative advantage, it has comparative advantage where it focuses. In technical terms, the advantage is endogenous—it emerges from the behavior of the participants. Paul Krugman won his Nobel Prize in part for advancing this theory.
The giveaway that Drezner is having the wrong conversation is his statement that, “If you believe that reworking the global supply chain right now would uncover untold efficiencies, you need to pick up a newspaper.” To my knowledge, no one has ever claimed that reshoring would lead to productivity gains through the “uncovering of efficiencies,” as if there were low-hanging fruit waiting to be plucked. Indeed, if that were the case, firms would presumably have done it themselves.
The premise, to the contrary, is that the long-term gains are not ones quickly or easily captured by an individual firm maximizing its own profit, which is precisely why they are not being pursued and do require public policy. But an imperative and/or incentives to manufacture domestically would force firms to invest in raising productivity, such investment—as well as the very presence of the domestic production—would spur innovation, and over time both the sector and the broader economy would achieve higher levels of productivity growth than the woefully stagnant ones being delivered under the “offshore-manufacturing-but-create-lots-of-barre-instructor-jobs” formula embraced by those who reap the benefits of both the offshoring and the barre classes.
That story could be right or wrong. People could have an informed economic argument about it. But not while analyzing economics as Drezner does through the narrow, blurred lens of “what is the most efficient way to do things right this moment, holding everything else constant and in perpetuity.” Such thinking has not served our economy well.

In the Wall Street Journal today, former Treasury Secretary Hank Paulson gives a rundown of the generic case for “How American Free Trade Can Outdo China.” Three things jump out: 1. He leads with the point that, “America’s economic prosperity and the effectiveness of our political system and global leadership are rooted in domestic economic […]
Although neoliberal globalists are often said to be opposed to industrial policy and strategic trade, that is not necessarily true. Neoliberals of the kind who have dominated U.S. policy under the two Bushes, Bill Clinton and Barack Obama are not orthodox anti-government libertarians. They support a particular kind of industrial policy, whose emblem is not […]
