Which measure adjusts income to reflect differences in cost of living between countries, indicating how much money is needed to purchase the same goods and services?

• A. HDI
• B. Purchasing Power Parity (PPP)
• C. Renewable Energy
• D. Microfinance

Answer: (B)

Purchasing power parity shows how far money goes in different countries by adjusting income for price level differences. It compares the cost of a standard basket of goods and services in each country, so the income you report reflects what that money can actually buy locally, not just what currency exchanges for. This makes PPP useful for comparing living standards because it neutralizes distortions from different price levels and exchange rates. For example, if the same basket costs more in one country, PPP-based income will be higher there to reflect the higher local prices. The other options don’t perform this role: HDI combines health, education, and income but doesn’t adjust for local prices; renewable energy is unrelated to income comparisons; microfinance concerns lending and financial inclusion, not price-adjusted income across countries.
