## Purchasing power parity exchange rate models

Purchasing power parities (PPPs) are the rates of currency conversion that try to equalise the purchasing power of different currencies, by eliminating the  Monopolistic competition The model of monopolistic competition describes a common market structure in which firms have many competitors, but each one sells a  It is a theoretical exchange rate that allows you to buy the same amount of goods and services in every country. Government agencies use PPP to compare the

Purchasing power parity refers to the exchange rate of two different currencies that are going to be in equilibrium and PPP formula can be calculated by multiplying the cost of a particular product or services with the first currency by the cost of the same goods or services in US dollars. Using market exchanges rates, such as \$1 = ¥200, or: Using purchasing power parities (PPPs) Market exchange rates. Using market exchange rates creates two main difficulties: Firstly, market exchange rates can quickly change, which artificially changes the value of the variable in question, such as GDP. For example, a one-month appreciation of the US\$ by 5% against the Japanese Yen would reduce the dollar value of the Japanese economy by 5%. As a country develops, it is generally believed that more goods will be traded and that the gap between the PPP exchange rate and the market exchange rate will diminish. PPP ratios help in making more meaningful comparisons of living standards in different countries. Uses of Purchasing Power Parity Purchasing-power parity (PPP) is an economic concept that states that the real exchange rate between domestic and foreign goods is equal to one, though it does not mean that the nominal exchange rates are constant or equal to one. Updated August 29, 2019. Purchasing power parity is a theoretical exchange rate that allows you to buy the same amount of goods and services in every country. It's a theoretical rate because no country actually uses it. But government agencies use it to compare the output of countries that use different exchange rates.
