PURCHASING POWER PARITY Meaning and
Definition
-
Purchasing power parity (PPP) refers to an economic concept used to measure and compare the relative value of different currencies. It is a theory that states the exchange rate between two currencies should be adjusted in a way that ensures identical purchasing power in both countries. In other words, PPP suggests that the cost of living and inflation rates should be taken into account when determining exchange rates, as opposed to simply looking at nominal values.
The primary goal of using purchasing power parity is to facilitate price comparisons and evaluate the standard of living in different countries. By accounting for disparities in price levels, PPP allows for a more accurate assessment of purchasing power across nations. The theory implies that a unit of currency should have the same value in terms of what it can buy, regardless of the country in which it is used.
Calculating purchasing power parity involves comparing the prices of identical goods and services in different countries and adjusting exchange rates accordingly. This adjustment considers factors such as inflation rates, average income levels, and cost of essential items. PPP is often used in international economics to analyze global trade patterns, determine currency valuations, and assess differences in economic development among nations.
Overall, purchasing power parity is a concept that provides a framework for understanding and comparing the real purchasing power of different currencies, eliminating the misleading influence of nominal exchange rates.
