Estados Unidos e China em comparação

We invite you to predict when China will overtake America
AMERICA'S GDP is still roughly twice as big as China’s (using market exchange rates). To predict when the gap might be closed, The Economist has updated its interactive chart below with the latest GDP numbers. This allows you to plug in your own assumptions about real GDP growth in China and America, inflation rates and the yuan’s exchange rate against the dollar. Over the past ten years, real GDP growth averaged 10.5% a year in China and 1.6% in America; inflation (as measured by the GDP deflator) averaged 4.3% and 2.2% respectively. Since Beijing scrapped its dollar peg in 2005, the yuan has risen by an annual average of just over 4%. Our best guess for the next decade is that annual GDP growth averages 7.75% in China and 2.5% in America, inflation rates average 4% and 1.5%, and the yuan appreciates by 3% a year. Plug in these numbers and China will overtake America in 2018. Alternatively, if China’s real growth rate slows to an average of only 5%, then (leaving the other assumptions unchanged) it would not become number one until 2021. What do you think?
