A decade ago, the business cycle was an endangered species.
Recessions in the rich world had become rare, shallow and short; inflation was predictably low and boring. Economists dubbed this the “Great Moderation” and gave credit for it to deft macroeconomic management by central banks. Such talk, naturally, ended abruptly with the financial crisis.
But obituaries of the Great Moderation may have been premature. Since America emerged from recession in 2009, its growth, although low, has been as stable as during the Great Moderation’s heyday, from the early 1980s to 2007, judging by the volatility of quarterly gross domestic product (see chart) and monthly job creation.
