Krugman on the Market
Paul Krugman, writing in the NYT, points out that the recent market turbulence triggered by China is part of a pattern of instability.
But why does the world economy keep stumbling?
On the surface, we seem to have had a remarkable run of bad luck. First there was the housing bust, and the banking crisis it triggered. Then, just as the worst seemed to be over, Europe went into debt crisis and double-dip recession. Europe eventually achieved a precarious stability and began growing again — but now we’re seeing big problems in China and other emerging markets, which were previously pillars of strength.
But these aren’t just a series of unrelated accidents. Instead, what we’re seeing is what happens when too much money is chasing too few investment opportunities.
More than a decade ago, Ben Bernanke famously argued that a ballooning U.S. trade deficit was the result, not of domestic factors, but of a “global saving glut”: a huge excess of savings over investment in China and other developing nations, driven in part by policy reactions to the Asian crisis of the 1990s, which was flowing to the United States in search of returns. He worried a bit about the fact that the inflow of capital was being channeled, not into business investment, but into housing; obviously he should have worried much more. (Some of us did.) But his suggestion that the U.S. housing boom was in part caused by weakness in foreign economies still looks valid.
Too much of the world's wealth is owned by those who don't want to spend it.
