## What is purchasing power equality?

Purchasing power parity (PPP) is a theory which states that exchange rates between currencies are in equilibrium when their purchasing power is the same in each of the two countries.

Purchasing power is the value of a currency expressed in terms of the number of goods or services that one unit of money can buy. It can weaken over time due to inflation. That’s because rising prices effectively decrease the number of goods or services you can buy.

What is purchasing power parity with example?

This means that goods in each country will cost the same once the currencies have been exchanged. For example, if the price of a Coca Cola in the UK was 100p, and it was \$1.50 in the US, then the GBP/USD exchange rate should be 1.50 (the US price divided by the UK’s) according to the PPP theory.

How is PPP measured?

Purchasing power parity (PPP) is measured by finding the values (in USD) of a basket of consumer goods that are present in each country (such as pineapple juice, pencils, etc.). If that basket costs \$100 in the US and \$200 in the United Kingdom, then the purchasing power parity exchange rate is 1:2.

### Why is purchasing power parity important?

Purchasing power parity is important for developing reasonably accurate economic statistics to compare the market conditions of different countries. For example, purchasing power parity is often used to equalize calculations of gross domestic product.

Purchasing power refers to the number of goods or services that a certain amount of money can buy at a given time.

What are the different types of purchasing power?

There are two forms of the Purchasing Power Parity: absolute and relative.
