Paul Krugman gives some much needed attention to deficit financing today. More specifically, he takes on the current trade imbalance between China and the U.S.:

"Money is pouring into China, both because of its rapidly rising trade surplus and because of investments by Western and Japanese companies. Normally, this inflow of funds would be self-correcting: both China's trade surplus and the foreign investment pouring in would push up the value of the yuan, China's currency, making China's exports less competitive and shrinking its trade surplus.

"But the Chinese government, unwilling to let that happen, has kept the yuan down by shipping the incoming funds right back out again, buying huge quantities of dollar assets - about $200 billion worth in 2004, and possibly as much as $300 billion worth this year. This is economically perverse: China, a poor country where capital is still scarce by Western standards, is lending vast sums at low interest rates to the United States.

"Yet the U.S. has become dependent on this perverse behavior. Dollar purchases by China and other foreign governments have temporarily insulated the U.S. economy from the effects of huge budget deficits. This money flowing in from abroad has kept U.S. interest rates low despite the enormous government borrowing required to cover the budget deficit."

I've talked about this a little before, but I'm not an economist, and I certainly haven't won anything nearly as prestigious as the John Bates Clark medal.

Hopefully people will pay a little more attention to Krugman.
