It's really not a good idea, is it my own fault? The Big Mac Index is a very small number.

The Big Mac index is not formally known as the Big Mac index, but rather as the Big Mac index. This index is a world of goods in the world price difference to indirectly reflect the other currencies around the world relative to the dollar exchange rate is reasonable. The theory of this index was launched in September 1986 by the editors of The Economist.

The reason for using McDonald's Big Macs is that they are available in many countries and are made to the same specifications everywhere, with the local McDonald's distributor being responsible for bargaining for the materials. Because of this, the use of the Big Mac allows the index to easily and relatively accurately reflect the real purchasing power of currencies around the world, i.e., to show the parity of currencies around the world. The index is based on the price of Big Macs in the United States, and compares the price of Big Macs converted to U.S. dollars, so as to understand the extent to which currencies are overvalued or undervalued. If the price of a Big Mac is more expensive than in the United States, it means that the currency is overvalued.

While it may seem fair to use a single price that is distributed around the world, the cost of a Big Mac varies from place to place and does not include data such as rents and wages, which are relatively low in less developed areas, nor does it take into account that the demand for Big Macs varies from one country to the next. Therefore, the Big Mac index alone is not a formal currency speculation and can only be regarded as an informal economic index.

The real value of a currency is not based on the internal value of the economy

Even if a country is starved of money, it can still be the strongest economy with the largest GDP,
