While economists widely cite the Big Mac index as a reasonable real-world measurement of purchasing power parity, the burger methodology has some limitations. This value is then compared with the actual exchange rate if it is lower, then the first currency is under-valued (according to PPP theory) compared with the second, and conversely, if it is higher, then the first currency is over-valued. The Big Mac PPP exchange rate between two countries is obtained by dividing the price of a Big Mac in one country (in its currency) by the price of a Big Mac in another country (in its currency). For these reasons, the index enables a comparison between many countriesвЂ™ currencies. The Big Mac was chosen because it is available to a common specification in many countries around the world as local McDonaldвЂ™s franchisees at least in theory have significant responsibility for negotiating input prices. In the Big Mac Index, the basket in question is a single Big Mac burger as sold by the McDonaldвЂ™s fast food restaurant chain.

One suggested method of predicting exchange rate movements is that the rate between two currencies should naturally adjust so that a sample basket of goods and services should cost the same in both currencies. The index also gave rise to the word burgernomics.

The Big Mac index was introduced in The Economist in September 1986 by Pam Woodall as a semi-humorous illustration of PPP and has been published by that paper annually since then. It вЂњseeks to make exchange-rate theory a bit more digestibleвЂќ. The Big Mac Index is published by The Economist as an informal way of measuring the purchasing power parity (PPP) between two currenciesВ and provides a test of the extent to which market exchange rates result in goods costing the same in different countries. However, in some cities, the price of a Big Mac can be as high as 156 rubles ($2.50), according to economist Kirill Tremasov, cited in news website The Bell.McDonaldвЂ™s prices around the world are an incredibly useful means to measuring purchasing power parity between countries but how much does a McDonaldвЂ™s meal cost around the world for a South African. at $5.74 and in Russia at just 130 rubles ($2). The Big Mac index is calculated according to data that puts the price of a Big Mac in the U.S. Today, the index measures the price of a Big Mac in every country that has a McDonald's restaurant.Д«ut itвЂ™s not always been a happy meal for The Economist, which has faced criticism for not taking into account variations in the price of a Big Mac in different cities. The Economist launched the Big Mac index in 1986 as a handy guide for assessing whether currencies are at the correct level according to the theory of purchasing-power parity. The Big Mac index suggests it should cost 22.65 rubles for $1, but in reality the price of a dollar is 63 roubles. The publicationвЂ™s research indicated that the Russian currency is undervalued by a whopping 64.5%, up from 70.4% six months ago. The ruble is the most undervalued currency on The EconomistвЂ™s Big Mac index.
