What is the difference between PPP and market exchange rates when measuring development?

• A. PPP adjusts for cost of living differences, giving a more accurate comparison of real living standards; market exchange rates reflect currency values for trade but can distort comparisons.
• B. PPP overstates currency values for trade.
• C. Market rates adjust for living costs.
• D. They are identical in measuring development.

Answer: (A)

The main idea is that price levels differ across countries, so how we convert incomes matters for judging development. Purchasing Power Parity (PPP) adjusts for these cost-of-living differences by valuing a common basket of goods in each country, using a shared currency. This means PPP gives a closer estimate of what people can actually buy with their income, so it’s a better measure of real living standards across nations. Market exchange rates, on the other hand, reflect the value of currencies in international trading and financial markets. They show what currencies exchange for in trade, but they can be pulled away from domestic prices by inflation, speculation, and other financial factors. Because of that, using market rates can distort comparisons of living standards, since a country with high inflation or volatile capital flows might look poorer or richer than its actual domestic purchasing power suggests. So, PPP is preferred for comparing real living standards because it accounts for how expensive goods and services are locally, while market rates tell you about currency values in trade but can misrepresent what people can actually afford at home.
