Calculations Quote by Thomas Pogge
“Purchasing power parities are not a reasonable method for comparing households across countries or currencies. The reason for this is simply that PPPs are sensitive to the prices of all the commodities, goods and services, that households are consuming worldwide, with each commodity weighted in the calculations according to its share in international household consumption expenditure.”
About This Quote
PPPs compare purchasing power using average consumption baskets, which differ widely across nations, making them unreliable for household-level comparisons across currencies.
In simple terms: PPPs are unreliable for comparing household costs across countries.
Key Takeaway
Avoid using PPPs for direct household cost comparison.
