Purchasing power parity (PPP) [1] is a measure of the price of specific goods in different countries and is used to compare the absolute purchasing power of the countries' currencies. PPP is effectively the ratio of the price of a market basket at one location divided by the price of the basket of goods at a different location.
Relative Purchasing Power Parity is an economic theory which predicts a relationship between the inflation rates of two countries over a specified period and the movement in the exchange rate between their two currencies over the same period. It is a dynamic version of the absolute purchasing power parity theory. [1] [2]
Consistent with PPP economic theory, the Big Mac index also provides a method to analyse a currency's level of under/over-valuation against a base currency. [9] In order to calculate whether a currency is under/over-valued, the implied exchange rate (as defined by the Big Mac index) must be compared to the actual exchange rate.
Similarly, the impact of economic activity on the environment is not measured in calculating GDP. Comparison of GDP from one country to another may be distorted by movements in exchange rates. Measuring national income at purchasing power parity may overcome this problem at the risk of overvaluing basic goods and services, for example ...
GDP (PPP) means gross domestic product based on purchasing power parity. This article includes a list of countries by their forecast estimated GDP (PPP). [2] Countries are sorted by GDP (PPP) forecast estimates from financial and statistical institutions that calculate using market or government official exchange rates.
Key takeaways. Inflation is a sustained increase in prices of goods and services, which can negatively impact purchasing power and lead to tough financial decisions for consumers.
A country's gross domestic product (GDP) at purchasing power parity (PPP) per capita is the PPP value of all final goods and services produced within an economy in a given year, divided by the average (or mid-year) population for the same year.
The deviation in Purchasing power parity allows rural Indians to survive on an income below the absolute subsistence level in the rich world (One can use this link to calculate PPP difference between currencies).If the money income levels are taken as given, then all else being equal, the Penn effect is beneficial.
