NEW DELHI – In the movie “Groundhog Day,” a television weatherman, played by Bill Murray, awakes every morning at 6:00 to relive the same day. A similar sense of déjà vu has pervaded economic forecasting since the global economic crisis began a half-decade ago. Yet policymakers remain convinced that the economic-growth model that prevailed during the pre-crisis years is still their best guide, at least in the near future.
Consider the mid-year update of the International Monetary Fund’s World Economic Outlook, which has told the same story every year since 2011: “Oops! The world economy did not perform as well as we expected.” The reports go on to blame unanticipated factors – such as the Tōhoku earthquake and tsunami in Japan, uncertainty about America’s exit from expansionary monetary policy, a “one-time” re-pricing of risk, and severe weather in the United States – for the inaccuracies.
Emphasizing the temporary nature of these factors, the reports insist that, though world GDP growth amounted to roughly 3% during the first half of the year, it will pick up in the second half. Driven by this new momentum, growth will finally reach the long-elusive 4% rate next year. When it does not, the IMF publishes another rendition of the same claims.
This serial misjudgment highlights the need to think differently. Perhaps the focus on the disruptions caused by the global financial crisis is obscuring a natural shift in developed economies to a lower gear following years of pumped-up growth. Moreover, though emerging economies are also experiencing acute growth slowdowns, their share of the global economic pie will continue to grow. In short, tougher economic competition, slower growth, and low inflation may be here to stay.
