China's GDP is a bit less than half that of the U.S by conventional measures.; its population is about four times as large, and its rate of annual GDP growth about triple. The IMF is now
forecasting that China's GDP will surpass that of the U.S. by 2016.
The IMF gets to that watershed so quickly in large part by adjusting current figures for "purchase power parity" (PPP)-- that is, adjusting for the artificially low exchange value of the yuan. PPP-adjusted, the IMF pegs China's current GDP at about 74% that of the U.S., as opposed to approximately 40% in 2010 as conventionally measured, according to
IMF figures.
Brett Arends, reporting this forecast in Marketwatch,
concludes:
This is more than a statistical story. It is the end of the Age of America. As a bond strategist in Europe told me two weeks ago, “We are witnessing the end of America’s economic hegemony.”
I wonder if that is necessarily so. Certainly not immediately. At present, the European Union's economy is larger than that of the U.S., but it projects nowhere near the comparable military or soft power.
While China's population is about four times that of the U.S., its
per capita income, by conventional measures, was a bit less than 1/10 as large in 2010, according to the IMF. Call it 1/6, PPP-adjusted. China spends 2.2% of GDP on its military,
compared to 4.7% in the U.S (Stockholm International Peace Research Institute). It collects 17% of GDP in taxes,
compared to 28% for the U.S (Heritage).
