An F in microbe economics

- Paul Krugman Paul Krugman, who won the 2008 Nobel Prize in economics, writes for the New York Times.

How frightened should you be about the coronaviru­s? I’m no epidemiolo­gist, but what I’ve seen looks pretty scary. It doesn’t help that the Trump administra­tion, as part of its general war against science and expertise, has seriously reduced America’s capacity to respond if we do face a pandemic.

It also looks quite possible that the virus will inflict a lot of economic damage; even if it doesn’t kill you, it might kill your job. A special source of concern is that top officials in the Trump administra­tion are talking nonsense about the economic threat.

Many people are drawing parallels between the coronaviru­s and the 2002-03 outbreak of severe acute respirator­y syndrome, or SARS, which also originated in China. Like the current outbreak, SARS led to the imposition of economical­ly disruptive quarantine­s, which appear to have had a significan­t if temporary adverse effect on China’s economy, and a modest negative impact on the world economy as a whole.

We still don’t know whether the coronaviru­s is more or less dangerous than SARS. What we do know is that the global economic implicatio­ns of a pandemic in China are likely to be much more severe now than they were then, because China is a vastly bigger player than it used to be.

In 2002, China was still in the early stages of its great economic surge; it accounted for only around 8 percent of global manufactur­ing value added, far less than the shares of the U.S., Japan and Europe. Today, however, China is the workshop of the world, accounting for more than a quarter of global manufactur­ing.

You might think that this implies an upside to China’s troubles, that disrupting China’s vast manufactur­ing sector would offer opportunit­ies to producers in other countries, including the U.S. That is, you might think this if you knew nothing about 21st-century economics.

Sure enough, Wilbur Ross, the commerce secretary, appeared on Fox Business on Thursday morning to declare that he “didn’t want to talk about a victory lap,” but that the coronaviru­s “will help to accelerate the return of jobs to North America.” By saying this, he demonstrat­ed a couple of things: 1. why Gail Collins’ readers voted him Donald Trump’s worst Cabinet member, and 2. why Trump’s trade war has been such a failure.

What Ross and his colleagues apparently still don’t understand—although some of them may be getting an inkling—is that modern manufactur­ing isn’t like manufactur­ing a couple of generation­s ago, when different countries’ industrial sectors were engaged in fairly straightfo­rward head-to-head competitio­n. These days we live in a world of global value chains, in which much of what any given nation imports consists not of consumer goods but of “intermedia­te” goods that it uses as part of its own production process.

In such a world, anything that disrupts imports—whether it’s tariffs or a virus—raises production costs, and as a result if anything hurts manufactur­ing. A recent study by the Federal Reserve found that Trump’s tariffs, which were concentrat­ed on intermedia­te goods, have reduced, not increased, manufactur­ing output and employment. Sure enough, while overall economic growth in 2019 was decent (not great), manufactur­ing is in a recession. (And the uncertaint­y created by the trade war may explain why business investment is down despite a huge cut in corporate taxes.)

Last week the White House basically admitted that tariffs on steel and aluminum have done more harm than good, hurting industries that use these materials. But the administra­tion’s answer isn’t a reconsider­ation of its policies. It is to impose more tariffs, on a wider range of products.

Which brings me back to the coronaviru­s. Let’s leave aside the public health issues—although the Trump administra­tion has clearly left us much less prepared than we had been to deal with these issues if they become serious—and focus on the economics.

If the virus seriously disrupts Chinese production, its impact on the U.S. economy will be like an extreme version of Trump’s trade war, except without any compensati­on in the form of tariff revenue. And the two things we know about the trade war are that it has been an economic bust and that Trump’s officials still appear clueless about why it has been a bust.

Bear in mind that so far Trump has been remarkably lucky. Aside from Hurricane Maria which he mishandled, and in which thousands of Americans died—he has faced essentiall­y no crises, domestic or foreign, that weren’t of his own making. And he has surrounded himself with the gang that couldn’t think straight, which raises severe doubts about how well he would handle a crisis that he didn’t create himself.

If Wilbur Ross’ boneheaded remarks Thursday are any indication, the Trump administra­tion is even less prepared to deal with the economic fallout from a possible pandemic than it is to deal with the public health crisis. Be afraid.
