The Big Mac economy
Our hypothesis has not been proven to be true. As the GDP per capita of the country increases, the price of the Big Mac does not necessarily increase.
The currencies of some countries are undervalued or overvalued due to foreign exchange trading. The Big Mac Index was created to test the exchange rates in an informal way, by comparing the buying power of consumers in different countries using the Purchasing Power Parity (PPP).
The project can be repeated by comparing prices of other international food chains like Pizza Hut or Burger King.
Try to repeat the project to compare prices for countries within Asia and countries within Europe.
