## How do you calculate relative purchasing power parity?

How to Calculate Relative Purchasing Power Parity

1. Subtract one country’s inflation rate from the reference country’s inflation rate.
2. Add 1 to the compared country’s inflation rate.
3. Divide the difference in Step 1 by the sum in Step 2.

## What is the purchasing power parity method?

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. The basis for PPP is the “law of one price”.

## What does PPP mean in economics?

The other approach uses the purchasing power parity (PPP) exchange rate—the rate at which the currency of one country would have to be converted into that of another country to buy the same amount of goods and services in each country. To understand PPP, let’s take a commonly used example, the price of a hamburger.

## Why is relative purchasing power parity important?

The theory holds that inflation will reduce the real purchasing power of a nation’s currency. RPPP also complements the theory of absolute purchasing power parity (APPP), which maintains that the exchange rate between two countries will be identical to the ratio of the price levels for those two countries.

## What is the difference between relative and absolute PPP?

Note the difference between the absolute and relative PPP. The absolute PPP indicates that the exchange rate has to reflect the ratio of two countries’ price levels. All the relative PPP requires is the changes in the exchange rate equal the changes in the ratio of the price level.

## What is the difference between GDP and PPP?

Gross domestic product (GDP) in purchasing power standards measures the volume of GDP of countries or regions. it is calculated by dividing GDP by the corresponding purchasing power parity (PPP), which is an exchange rate that removes price level differences between countries.

## Why is PPP used?

Purchasing power parity (PPP) is a popular metric used by macroeconomic analysts that compares different countries’ currencies through a “basket of goods” approach. Purchasing power parity (PPP) allows for economists to compare economic productivity and standards of living between countries.

## Why is relative PPP better than absolute?

The absolute PPP indicates that the exchange rate has to reflect the ratio of two countries’ price levels. However, this is not easy. Therefore, the relative PPP takes these market imperfections in consideration and relaxes the relationship between the exchange rate and the price levels of two countries.
