Aug. 3, 20111 (Bloomberg) -- Economics isn’t rocket science, but the U.S. economy is a little like a rocket. If it has enough thrust, it can escape the tug of economic gravity. Not enough, and it just might go into a tailspin. Economists at the Federal Reserve and elsewhere are studying whether today’s slow growth is a precursor to an outright recession -- and if so, why.
It’s widely accepted that a slowly growing economy is more likely to tip into recession, for the obvious reason that it’s already too close to the line; any shock can knock it into negative territory. And today’s slow growth is at least in part a symptom of underlying problems such as consumer indebtedness, high energy prices, and the jitters induced by debt ceiling brinkmanship, Bloomberg Businessweek reports in its Aug. 8-14 edition.
What’s harder to prove is the hypothesis that slowness is not just a symptom of trouble but a cause of it. In other words, some economists say, if the economy grows too weakly, that slowness itself could create conditions that lead to a recession. Why? Maybe the sluggishness undermines consumer and business confidence. Maybe investors lose faith in the recovery so stock prices, already down 9 percent from their April high, plummet. Or maybe lenders get nervous about borrowers’ ability to repay loans and start withdrawing credit. Any such reaction could cause the very downturn that’s feared. “When the growth rate gets low enough, certain factors may kick in, nonlinearly,” says Menzie Chinn, an economist at the University of Wisconsin at Madison and co-author of a new book, “Lost Decades.”
