Which measure is used to compare living standards across countries after adjusting for price differences?

• A. Market exchange rates.
• B. Purchasing power parity.
• C. Nominal GDP per capita.
• D. Average wage rates.

Answer: (B)

When comparing living standards across countries, you want to know how much people can actually buy with their money, not just the nominal amount of money they earn or the current exchange rate. Purchasing power parity adjusts for price level differences between countries. It uses a standard basket of goods and services and expresses income in an international unit, so one unit buys roughly the same amount of goods everywhere. This makes real living standards comparable by removing distortions from different price levels and exchange rates. Market exchange rates show currency values in financial markets and can swing for reasons unrelated to local prices, so they don’t accurately reflect buying power. Nominal GDP per capita uses current prices without adjusting for how expensive things are in each country. Average wage rates measure earnings but don’t capture overall what people can purchase, which depends on prices and living costs.
