Purchasing power parity

Purchasing power parity (PPP) is a measure used to compare the absolute purchasing power of different countries' currencies by adjusting for price level differences. It calculates the ratio of the price of a market basket at one location to the price of the same basket at another location, allowing for a more accurate comparison of economic productivity and living standards.

The PPP indicator can be used to compare economies based on their GDP, labor productivity, and actual individual consumption. It also helps in analyzing price convergence and comparing the cost of living between places. The calculation involves a basket of goods that includes consumer goods, services, government occupations, equipment goods, and construction projects.

Estimation of PPP is complicated by differences in consumption patterns and price levels across countries. People in different countries typically consume different quantities and types of goods and services, making it challenging to create a uniform basket of goods for comparison.
