Which informal metric compares purchasing power parity by using the price of a Big Mac in different countries?

• A. Gross Domestic Product
• B. GNI
• C. Multidimensional Poverty Index
• D. Big Mac Index

Answer: (D)

The Big Mac Index is an informal way to compare purchasing power parity by using the price of a Big Mac in different countries. It takes how much local currency you need to buy a Big Mac, converts that to a common currency using current exchange rates, and compares it to the price of a Big Mac in the base country. If the local Big Mac is pricier than the base-country price after conversion, the local currency is seen as overvalued relative to PPP; if it’s cheaper, the currency looks undervalued. This simple, tangible benchmark helps illustrate how much a currency actually buys in practice, beyond official exchange rates. Of course, it’s not a precise measure—local costs, taxes, labor, and branding affect prices—so it’s best used for intuition rather than exact calculations. Other metrics like GDP, GNI, or the Multidimensional Poverty Index focus on overall output, income, or welfare, not a single consumer good used to compare price levels.
