Some events give extraordinary insights into the biases of the economics profession. The trade war with China clearly fit the bill.
The origins of the trade war can be traced to campaign promises Trump made to go after China over its large trade surplus with the United States, which he attributed to "currency manipulation." The argument was that by intervening in currency markets (buying up U.S. dollars), China was propping up the value of the dollar against its own currency.
This makes Chinese goods and services relatively cheaper to U.S. consumers and makes U.S. goods more expensive to Chinese purchasers. The net effect is to increase U.S. imports of Chinese goods and reduce U.S. exports to China, thereby leading to a large trade deficit.
While most economists now acknowledge that China was intervening in currency markets in the last decade (they did not acknowledge the currency intervention at the time), they insist that this is no longer an issue. China is no longer a large net buyer of dollar denominated assets, so the argument goes, therefore it is not currently keeping down the value of its currency against the dollar.
As I have argued elsewhere, this argument ignores the effect of China holding well in excess of $3 trillion worth of dollar denominated assets. Its decision to hold a massive stock of dollar assets depresses the value of the Chinese yuan against the dollar, thereby maintaining the competitive advantage from a lower valued currency.
This is the same logic that applies with the Fed's decision to hold trillions of dollars worth of assets that it acquired as part of its quantitative easing program. Even though the Fed is not currently buying assets, most economists argue that its holding of assets still works to keep down interest rates. Perhaps in the next decade they will acknowledge that the same relationship holds with China's massive stock of dollars and the relative value of the dollar and the yuan, but for now they insist that currency intervention was only an issue in the past.
This is important background, because currency values will directly affect our trade balance with China, and thereby impact the number of manufacturing jobs in the United States. While reducing the trade deficit will not get back most of the relatively high paying manufacturing jobs that were lost in the last decade, it would likely still be a plus for relatively less-educated workers who still rely on manufacturing as a source of higher paying jobs.
Although currency is mostly off the table in Trump's trade war, intellectual property is very much on the table. And here Trump has the support of economists across the political spectrum, who argue that he has a legitimate complaint, even if they don't endorse his go it alone cowboy tactics.
The compliant is that China is not respecting "our" intellectual property. This lack of respect takes two main forms. One is simply not honoring the patents, copyrights, and trademarks of U.S. corporations. The other is requiring technology transfers by U.S. corporations that locate operations in China. This usually means taking on a domestic Chinese company as a partner, which will then gain expertise in the use of the U.S. company's technology.
It is very impressive how the bulk of the economics profession has been willing to legitimate the switch in focus of Trump's trade war. He had run around the country in his campaign denouncing China as a world class currency manipulator. He pledged to take punitive actions against China for its currency practices on Day One of his administration. Getting China to raise the value of its currency against the dollar actually would have provided some benefit to U.S. workers. But now currency is off the table and we are fighting a trade war to protect "our" intellectual property.
If it's not obvious already, it is not "our" intellectual property that Trump and his bipartisan crew of economist cheerleaders are interested in protecting. It is the intellectual property of large corporations like Boeing, GE, Pfizer, and Microsoft. Very few people in the United States are in a position where they have to worry about China using their patents or copyrights without compensation. This is a real concern to many large U.S. corporations. The question is whether it should be a concern to the rest of us.
Most immediately, the concerns of ordinary workers are likely to go in the opposite direction. If companies like Boeing and General Electric don't have to worry about being forced to transfer technology to Chinese companies when they outsource to China, they will have more incentive to outsource to China. That's about as straightforward as it gets. Instead of reducing our trade deficit in manufacturing goods, this change is likely to increase it.
But this goes to an even deeper issue. We have seen a massive increase in wage inequality over the last four decades. Most economists probably believe some version of the skills biased technical change story that new technologies have placed a greater premium on skills like math, science, and engineering while reducing the value of less-educated workers.
Trump's trade war gives us an insight into the real story. It was not technology that led him to focus his efforts on protecting intellectual property to the neglect of currency issues; it was a political decision made in response to the political power of the most affected groups. And, Boeing, GE, and the rest have far more political power than the workers who labor in their factories or indeed, less-educated workers as a class.
