Switzerland where you can eat the most expensive Big Mac

Invented in 1986 as a light-hearted guide to purchasing power parity, the Big Mac Index compares the cost of a McDonald’s Big Mac burger in countries across the world, published by the Economist.
Using the US dollar as the base rate, Switzerland won the top spot again for the most expense burgers. A Swiss Big Mac costs $ 6.35 (CHF 6.50), compared to $ 5.06 in the US, meaning the Swiss franc is overvalued by 25.5%. 
 
The exchange rate that would equalize the price of a burger in the two countries is 1.28 francs to the dollar, while the actual exchange rate is 1.02 francs.
 
Norway has the second priciest Big Mac in the world at $5.67, followed by Sweden $5.26, Venezuela $5.25, Brazil $5.12 and the U.S. $5.06, according to the so-called Big Mac index.
The raw index doesn't take into account the cost of labour – how much people are paid to make the burger – which is likely to be much less in poorer countries – making the burgers much cheaper. 

The Economist also produces Big Mac index numbers using the euro and British pound as base currencies. In January 2017, in raw numbers, using the British pound as a base, a Swiss Big Mac was 70.3% overvalued. Using a euro base it was 56.3% overvalued. On a purchasing power basis, the Swiss franc was 26.9% overvalued in pounds, and 6.1% overvalued in euros. A year earlier, Swiss franc overvaluation against both of these currencies was 11% on a purchasing power basis.
 
The index's latest results were released ahead of the annual meeting of the World Economic Forum (WEF) in Davos, Switzerland.
