But not all economic downturns are the same, notes Grandmaster Rogoff.
The phrase “Great Recession” creates the impression that the economy is following the contours of a typical recession, only more severe – something like a really bad cold. That is why, throughout this downturn, forecasters and analysts who have tried to make analogies to past post-war US recessions have gotten it so wrong. Moreover, too many policymakers have relied on the belief that, at the end of the day, this is just a deep recession that can be subdued by a generous helping of conventional policy tools, whether fiscal policy or massive bailouts.Richard Florida's The Great Reset covers some of the same territory. Taken together, however, the deleveraging hypothesis calls for entirely different, not yet well-developed policy responses. Pump-priming or public works projects might be of dubious utility (although borrowing money for internal improvements at current interest rates might make economic sense, that is, if there were a proper government balance sheet).
But the real problem is that the global economy is badly overleveraged, and there is no quick escape without a scheme to transfer wealth from creditors to debtors, either through defaults, financial repression, or inflation.
A more accurate, if less reassuring, term for the ongoing crisis is the “Second Great Contraction.” Carmen Reinhart and I proposed this moniker in our 2009 book This Time is Different, based on our diagnosis of the crisis as a typical deep financial crisis, not a typical deep recession. The first “Great Contraction” of course, was the Great Depression, as emphasized by Anna Schwarz and the late Milton Friedman. The contraction applies not only to output and employment, as in a normal recession, but to debt and credit, and the deleveraging that typically takes many years to complete.
Why argue about semantics? Well, imagine you have pneumonia, but you think it is only a bad cold. You could easily fail to take the right medicine, and you would certainly expect your life to return to normal much faster than is realistic.
In a conventional recession, the resumption of growth implies a reasonably brisk return to normalcy. The economy not only regains its lost ground, but, within a year, it typically catches up to its rising long-run trend.
The aftermath of a typical deep financial crisis is something completely different. As Reinhart and I demonstrated, it typically takes an economy more than four years just to reach the same per capita income level that it had attained at its pre-crisis peak. So far, across a broad range of macroeconomic variables, including output, employment, debt, housing prices, and even equity, our quantitative benchmarks based on previous deep post-war financial crises have proved far more accurate than conventional recession logic.
