According to the Big Mac Index, the U.S. dollar is sizzling
The U.S. dollar is getting stronger, according to the closely watched or at least, heavily seasoned index of global currencies known as the Big Mac Index.
A series of world currencies have weakened against the dollar over the past year, according to The Economist, which puts this really-only-half-joking measure together.
The idea is that all things being equal the price paid for the same product around the world will tend toward equaling out. The theory is called purchasing-power parity and the index uses the concept and what it calls the notion of burgernomics to gauge the relative strengths of different currencies.
The Economist prices one product the Big Mac around the world and measures the change in its local cost over time. Oh, and in India, where there are wide religious objections to eating beef, they use the Maharaja Mac, a chicken sandwich.
