You probably do not know that in 1986 the Economist magazine invented a BigMac Index with the objective of estimating the standard of living in the countries where the McDonalds Group was present.  This particular product which is sold by the company in all the countries where it is present therefore enables the calculation of the estimated purchasing power of a country’s population by its price. Only one country is not included, India, as McDonalds does not sell beef products there.
