Make sure you are at least 35 years old and born in the United States. You must also have lived 14 years in America to run for President. (If you are not 35 yet, you can start planning early!). 1  There is no way around this. 2  No, Barack Obama was not born in Kenya.
What is 'Purchasing Power'. Purchasing power is the value of a currency expressed in terms of the amount of goods or services that one unit of money can buy. Purchasing power is important because, all else being equal, inflation decreases the amount of goods or services you would be able to purchase.
The concept of purchasing power parity allows one to estimate what the exchange rate between two currencies would have to be in order for the exchange to be at par with the purchasing power of the two countries' currencies.stimation of purchasing power parity is complicated by the fact that countries do not simply differ in a uniform price level; rather, the difference in food prices may be greater than the difference in housing prices, while also less than the difference in entertainment prices.
