GDP as a whole, should never be measured in PPP terms as it is simply meaningless. The entire economy of a country is only present in the world in nominal exchange rate parity. You don't exist in the global arena in YOUR prices. So, no, US is still the largest world economy, BY FAR. However, GDP per capita should be measured in PPP terms as it is a proxy for income per capita for individuals who spend their money in the home country, with domestic prices. You shouldn't read too much into the PPP though, since the international imports will still be traded in international prices, not necessarily domestic. In essence, even if country A's GDP/cap PPP is equal to country B's, the country with higher NOMINAL GDP/cap (and higher prices) is still better off, with greater purchasing power in internationally traded goods! |
There's also the fact that China is cheating by artificially keeping their currency low. That will eventually come back and bite them in their butts.
