The Big Mac Index is primarily a tool for comparing what across countries?

• A. Purchasing power parity
• B. Big Mac Index
• C. Tax rates
• D. Exchange rate stability

Answer: (A)

The Big Mac Index is a quick way to compare purchasing power parity across countries. Purchasing power parity means exchange rates should adjust so that the price of an identical good, like a Big Mac, is the same when priced in a common currency. By comparing the local price of a Big Mac in different countries and converting those prices to a common currency, we can infer whether a currency is under- or over-valued relative to PPP. This focuses on relative price levels and what money can buy, not on tax rates or how stable a currency’s exchange rate is over time. So, the main idea is to gauge PPP across nations using a single, globally standardized item.
