Countries with the Biggest Economies by GDP

PPP generally makes more sense than GDP for most international purposes though. PPP converts between currencies by using the prices of (basic) goods, GDP does it by using official exchange rates. The former is much more rooted in reality, while the latter is influenced by investors' "trust" in the currency. If the USD drops 20% vs the EUR it won't mean Americans get 20% poorer - just that imported goods and tourism in Europe gets more expensive, while domestic farms and industries consequently gets more competitive - and more tourists will likely arrive due to cheaper prices.

In a long time, but it will happen.

Haiti - though I'd hate to say this - is quite well known for its poverty and I'll assume that you are aware of this too. Its nominal GDP is at 761$ but its GDP PPP is at 1810$ and here you may see a huge discrepancy. The cause of discrepancy comes from the industrial context of Haiti. Haiti, like many other developing nations, lacks the industrial base to produce a lot of consumer goods on its own and thus it is mostly reliant on neighbouring DR for import of such. Now you may probably see the problem here. Though Haitians suffer from high living costs due to being charged the same prices for consumer goods as neighbouring DR (Because, it's not like DR would sell products at a devalued price because Haitians have a lower income than they have) while PPP will adjust the influence of the exchange rate when calculating the GDP PPP. Thus by using the GDP PPP, Haitians' purchasing power in actuality will be overvalued, hence the inaccuracy. And the Haitians are in good company as many othe

LEDCs also suffer from high living costs ignored by the GDP PPP, being reliant on imports for daily consumer goods. There is a reason why there was a time when Luanda was ranked the most expensive city in the World.

Plus there is a general argument that exchange rates are inseparable when we're to measure and compare the economic powers of countries. This is a quote from a WSJ article: ''China can’t buy missiles and ships and Iphones and German cars in PPP currency. They have to pay at prevailing exchange rates. That’s why exchange rate valuations are seen as more important when comparing the power of nations.". The quote saying the PPP is not adequate to measure what an economy can exactly do.

Sorry for that long read but if you did make it to this point, please do consider making the said changes? While GDP PPP is an undoubtedly useful figure, it seems quite inappropriate to use for a quiz that's "biggest economies quiz" - or so my opinion goes. Uh thank you for reading..?

dang unfortunate for Poland but its great to see other countries rising
