Despite its humorous origins, the index has become a global standard for comparing currency valuations and the relative cost of living in different countries. It is often cited in academic papers and economic textbooks as a practical example of PPP. The index is based on the theory of Purchasing Power Parity (PPP) . This economic theory states that in the long run, exchange rates should adjust so that a basket of goods (in this case, a Big Mac burger) costs the same in different countries when priced in the same currency.
