Relative Purchasing Power Parity Formula Example

The relative purchasing power parity definition discussed in the introduction can be expressed as a single formula thus the change in the spot price a b equals the inflation of the price currency a minus the inflation of the base currency b. Relative purchase power parity.

Purchasing Power Parity

Relative ppp versus absolute ppp.

Relative purchasing power parity formula example. The us and as such the formula can also be modified by dividing the cost of good x in currency 1 by the cost of the same good in the us dollar. Purchasing power parity ppp is an economic theory that allows the comparison of the purchasing power of various world currencies to one another. Purchasing power parity cost of good x in currency 1 cost of good x in currency 2.

According to the ppp when a country s inflation rate rises relative to that of the other country the former s currency is expected to depreciate. Purchasing power parity ppp is an economics theory which proposes that the exchange rate of any two currencies will remain equal to the ratio of their respective purchasing powers. In terms of the different ppp concepts such as absolute and relative ppp.

It is a theoretical exchange rate that allows you to buy the same amount of goods and services in every country. Purchasing power of a currency is measured as the amount of the currency needed to buy a selected product or basket of goods commonly available in different countries. An expansion of the purchase power parity theory which suggests that prices in countries vary for the same product but that they differ by the same proportional.

A popular practice is to calculate the purchasing power parity of a country w r t. The purchasing power parity ppp implies that the changes in two countries price levels affect the exchange rate. In this equation s is equal to the exchange rate of currency 1 and currency 2.

Rppp is calculated as follows. S p1 p2. This video discusses relative ppp its formulas and some examples.

Relative purchasing power parity formula. Purchasing power parity is an economic indicator used to calculate the exchange rate between different countries for the purpose of exchanging goods and services of the same amount. S p1 p2.

Meanwhile p 1 is the cost of a particular good let s say good x in currency 1 while p 2 is the cost of good x in currency 2. Purchasing power parity ppp is a popular metric used by macroeconomic analysts that compares different countries currencies through a basket of goods approach. What is relative purchasing power parity ppp and how does it link inflation to expected exchange rates.

So the formula of purchasing power parity can be defined as.
