The Big Mac Index: Law of One Price vs. PPP

From The Economist, "The Big Mac index (see chart above) is based on the idea of purchasing-power parity (PPP), which says currencies should trade at the rate that makes the price of goods the same in each country."

Technically, the Big Mac Index is more of a test of the Law of One Price, an economic law that says "In an efficient market all identical goods must have only one price." Purchasing Power Parity generally applies to a basket of goods.

  1. I wonder how much of the local prices are taxes? Is it possible to present this data tax-adjusted?

  5. Considering the top countries are Sweden, Norway, and Denmark, I'd bet taxes have something to do with it. I am surprised that it was cheaper in Australia. As for Malaysia, I wonder how much high price items cost there like cars. I've heard there is a high tariff on foreign cars.
