Purchasing power parity: understanding exchange rates and inflation

Posted on Jun 15, 2023 at 08:06 PM

The Purchasing power parity concept is a crucial indicator of converting different currencies into a single currency and comparing the two currencies with each other standard of living, wealth, and productivity.

Macroeconomics uses the so-called "commodity approach" to compare countries' growth and productivity.  As to analysing the inflation potential in each using data analysis tools.

The Purchasing power parity calculation depends on the Uniform Rate Act by converting currencies into one currency for easy comparison and eliminating the vast amount of data making it difficult to compare and analyse inflation and exchange rates. 

We will discuss the Purchasing power parity concept and its advantages and impact on the value of currencies and GDP.

What is Purchasing power parity?

Gustav Castle developed the purchasing power parity theory in 1920 to eliminate price differences between different countries when calculating purchasing power parity rates between them at a constant rate.

I am measuring purchasing power parity by converting different currencies into the distinct purchasing power equation. To help detect countries' total exchange rates and inflation globally.

The Purchasing power parity method provides a better understanding of the strength of the country's economy by knowing the country's wealth and the strength of its domestic currency because purchasing power parity-based GDP is the highest level showing the strength of different currencies based on its current economy.

How does Purchasing power parity determine exchange rates?

The Purchasing power parity theory between States determines exchange rate behaviour by codifying an individual's price for two different types of goods, calculating their respective exchange rates using the geometric mean. Thus obtaining the required joint integration.

In this way, we collect the economic data of the two commodities using Data Analysis Methods to show the difference between the currency's strength based on internal prices denominated in the local currency first and global prices denominated in the United States dollar currency, the most used globally.

What are the advantages of Purchasing power parity?

Now, here are the advantages to achieve when calculating the prices of products and services in different countries and parity of purchasing power after comparing the two currencies achieving price parity, which you can take advantage of if you enjoy procurement training courses in Dubai that provide you with a comprehensive and practical understanding of purchasing power parity:

• The Purchasing power parity calculation helps measure the country's current wealth.
• Shows which country suffers from inflation in its economy.
• Discover trade differences between the two countries and currencies' purchasing power efficiency rate.
• Use this effective measure to detect the country's economic health state.
• Identify the country with higher purchasing value according to purchasing power parity.
• Collect data on countries' economies subject to purchasing power parity theory to determine which economy is better than theirs.
• Calculating gross product gives Purchasing power parity and a better understanding of the differences between the two countries living standards.
• Give economists the ability to balance trade differences by making some adjustments.

What is Purchasing power parity's relationship to GDP?

GDP refers to the total monetary value of the country's services and products.

This hypothesis dropped when comparing any product or service between two different countries.

For example, let's say that the value of buying a cup of coffee in the United States is $4, and the importance of purchasing the same cup in Germany is €2.5 if you want to calculate the Purchasing power parity between the two countries for this cup of coffee. You first have to convert the currency of the euro to the United States dollar.

When calculated, a cup of coffee in Germany would equal approximately US $2.70, depending on the country's real exchange rate. 

Thus, the Purchasing power parity value here is 4/2.70, approximately 1.48.

How does it affect the value of currencies?

It is worth noting that the country's rate of domestic inflation affects the value of currencies influenced. as it affects the local currency concerning the United States dollar.

If the value of domestic Purchasing power parity is high, the currency exchange rate relative to the United States dollar will also be increased. 

Thus, affecting the value of the currency and the country's economy.

Suppose the domestic Purchasing power parity is low. In that case, the value of the country's currency will fall against the US dollar, and the government could suffer long-term inflation and affect it.

This shows the need to use the Purchasing power parity measure to detect inflation prospects and analyse the value of each country's exchange rates, to reduce the many economic risks that can occur, and to conduct profitable trade deals between countries based on the state of their economy.

In conclusion, 

GDP measurement of purchasing power parity (Purchasing power parity) at a constant rate between different countries shows a country's purchasing capacity levels by the Uniform Currency Act and the country's local currency exchange rate.

The purchasing power parity between each country for purchasing products and services to get all the advantages of this effective indicator.

It is necessary to see specialised training courses that use the correct theory to study Purchasing power parity globally and compare different currencies of different countries by a global economic measure known as the "commodity approach".
