McDonald's has become emblematic of globalization, sometimes referred to as the "McDonaldization" of society. "The Economist" newspaper uses the "Big Mac Index": the comparison of the cost of a Big Mac in various world currencies can be used to informally judge these currencies' purchasing power parity. Switzerland has the most expensive Big Mac in the world as of July 2015, while the country with the least expensive Big Mac is India (albeit for a Maharaja Mac—the next cheapest Big Mac is Hong Kong).
