What is The Economist Big Mac Index?
The Big Mac index, published The Economist, is a novel way of measuring whether the market exchange rates for different countries’ currencies are overvalued or undervalued. It does this by measuring each currency against a common standard – the Big Mac hamburger sold by McDonald’s restaurants all over the world.
How accurate is the Big Mac Index?
Our results indicate that the Big Mac Index is surprisingly accurate in tracking exchange rates over the long-term, which is consistent with previous PPP research findings.
How does the Big Mac index work as a measure of economic performance?
The Big Mac index is an informal way of measuring the purchasing power parity (PPP) between two currencies. By comparing the price of a McDonald’s hamburger in the US versus other countries, traders can establish the disparity between the purchasing power of the nations’ currencies.
What is a drawback of the Big Mac Index?
The index’s limitations are as follows: In many countries, dining at McDonald’s is relatively expensive when compared to dining at a local restaurant. Hence, the demand for a burger is relatively less. Hence, it doesn’t stand as globally acceptable.
Is the Big Mac Index a good measure of PPP?
This may sway the price of the Big Mac and throw off the ratio relative to the cost of the U.S. version. Despite this, the Big Mac Index is still a good starting point in determining currency discrepancies. The Index is an example of how PPP is used, but should not be considered the definitive comparison tool.
How do you tell if a currency is overvalued or undervalued?

Is the Big Mac Index accurate?

What does the GDP-adjusted index tell us about the economy?
The GDP-adjusted index addresses the criticism that you would expect average burger prices to be cheaper in poor countries than in rich ones because labour costs are lower. PPP signals where exchange rates should be heading in the long run, as a country like China gets richer, but it says little about today’s equilibrium rate.
