Purchasing power parity methods

Explanation:

Purchasing power parity (PPP) method compares the productivity and the standards of living between countries by using the 'basket of goods approach'.   The basket approach implies a determination of the quantity of money needed to purchase a common unit(basket) of goods and services in different countries.  Two countries will be said to be at par if a 'basket of goods' costs the same considering the exchange rates.

Cost of living and the inflation rate in a country determine the purchasing power of its currency. Purchasing power parity attempts to equalize different currencies by considering inflation and purchasing power in each country.
