WE GET BOTH CHEAP GOODS AND CHEAP LOANS, WHAT'S NOT TO LIKE?:

It’s No Time for Protectionism (N. GREGORY MANKIW, 2/08/09, NY Times)

Are Americans hurt by China’s exchange-rate policy?

Critics of China say it is keeping the yuan undervalued to gain an advantage in the international marketplace. A cheaper yuan makes Chinese goods less expensive in the United States and American goods more expensive in China. As a result, American producers find it harder to compete with Chinese imports in the United States and to sell their own exports in China.

There is, however, another side to the story. The loss to American producers comes with a gain to the many millions of American consumers who prefer to pay less for the goods they buy.

The situation is much the same as when the price of imported oil falls, as it has done in recent months. Domestic oil producers may see lower profits, but American consumers are better off every time they fill up their tanks. Consumers similarly gain when a cheap yuan reduces the prices of T-shirts and televisions imported from China.

Mr. Geithner and other China critics might also want to ponder how the Chinese keep the yuan undervalued. The essence of the policy is supplying yuan and demanding dollars on foreign-exchange markets. The dollars that China accumulates in these transactions are then invested in United States Treasury securities.

So when the Treasury secretary complains about the undervalued yuan, his message to the Chinese boils down to this: Stop lending us money.
