Paul Krugman: A Moveable Glut

 What' causing so much instability in the world economy?

A Moveable Glut, by Paul Krugman, Commentary, NY Times: What caused Friday’s stock plunge? What does it mean for the future? Nobody knows, and not much. ...
Still, investors are clearly jittery..., the world as a whole still seems remarkably accident-prone. ... But why does the world economy keep stumbling? ...
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... 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. ...
Of course, the boom became a bubble, which inflicted immense damage when it burst. Furthermore, that wasn’t the end of the story. There was also a flood of capital from Germany and other northern European countries to Spain, Portugal, and Greece. This too turned out to be a bubble, and the bursting of that bubble in 2009-2010 precipitated the euro crisis.
And still the story wasn’t over. With America and Europe no longer attractive destinations, the global glut went looking for new bubbles to inflate. It found them in emerging markets... It couldn’t last, and now we’re in the middle of an emerging-market crisis...
So where does the moving finger of glut go now? Why, back to America, where a fresh inflow of foreign funds has driven the dollar way up, threatening to make our industry uncompetitive again
What’s ... important now is that policy makers take seriously the possibility, I’d say probability, that excess savings and persistent global weakness is the new normal.
My sense is that there’s a deep-seated unwillingness, even among sophisticated officials, to accept this reality. Partly this is about special interests: Wall Street doesn’t want to hear that an unstable world requires strong financial regulation, and politicians who want to kill the welfare state don’t want to hear that government spending and debt aren’t problems in the current environment.
But there’s also, I believe, a sort of emotional prejudice against the very notion of global glut. Politicians and technocrats alike want to view themselves as serious people making hard choices — choices like cutting popular programs and raising interest rates. They don’t like being told that we’re in a world where seemingly tough-minded policies will actually make things worse. But we are, and they will.
