Based on purchasing power parity, GDP per capita (PPP). PPP GDP stands for buying power parity GDP, which is gross domestic product translated to foreign currencies using purchasing power parity rates. The purchasing power of an international dollar is equal to that of the US dollar in terms of GDP.
With an example, what is PPP GDP?
Purchasing power parity is an economic phrase that refers to the comparison of prices in different places. It is based on the law of one price, which states that if an item has no transaction costs or trade obstacles, its price should be the same everywhere. In an ideal world, a computer in New York and Hong Kong should cost the same. If a computer costs $500 in New York and 2,000 HK dollars in Hong Kong, according to PPP theory, the exchange rate should be 4 HK dollars for every 1 US dollar.
Poverty, taxes, transportation, and other frictions make it difficult to trade and buy a variety of items, so measuring only one can result in a big error. The PPP phrase accommodates for this by utilizing a basket of products, which consists of a variety of goods in various quantities. The ratio of the price of the basket in one location to the price of the basket in the other location is then computed using PPP as an inflation and exchange rate. If a basket containing one computer, one ton of rice, and one ton of steel costs 1,800 US dollars in New York and 10,800 HK dollars in Hong Kong, the PPP exchange rate is 6 HK dollars for every 1 US dollar.
The concept behind purchasing power parity is that with the proper exchange rate, consumers in all locations will have the same purchasing power.
The PPP exchange rate’s value is highly reliant on the goods basket chosen. In general, commodities that closely follow the law of one price are picked. As a result, ones are freely traded and widely available in both regions. Organizations that calculate PPP exchange rates utilize a variety of product baskets and can come up with a variety of results.
The PPP exchange rate may differ from the market rate. Because it reacts to variations in demand at each place, the market rate is more volatile. Tariffs and wage differentials (see BalassaSamuelson theorem) can also contribute to longer-term discrepancies between the two rates. PPP can be used to forecast longer-term exchange rates.
PPP exchange rates are utilized for many international comparisons, such as comparing countries’ GDPs or other national income figures, because they are more stable and less impacted by tariffs. These figures are frequently labeled as PPP-adjusted.
Purchasing power adjusted incomes and incomes translated using market exchange rates can differ significantly. The GearyKhamis dollar is a well-known buying power adjustment (the international dollar). According to the World Bank’s World Development Indicators 2005, one GearyKhamis dollar was worth around 1.8 Chinese yuan by purchasing power parity in 2003, a significant difference from the nominal exchange rate. This disparity has significant ramifications; for example, when converted using nominal exchange rates, India’s GDP per capita is roughly US$1,965, whereas it is about US$7,197 on a PPP basis. Denmark’s nominal GDP per capita is roughly US$53,242, but its PPP figure is US$46,602, which is comparable to other wealthy countries.
What does it mean to have a high PPP?
Prices are higher in richer nations, according to empirical evidence: there is a positive cross-country link between average earnings and average prices. This is demonstrated in the graph below, which graphs GDP per capita (in US dollars) against price levels (relative to the US). In the 1960s, Balassa and Samuelson formalized this observation, which is now known as the ‘Penn effect.’
It’s difficult to pinpoint the sources of the Penn effect, but economic theory offers some clues.
One theory, which has gotten a lot of attention in the academic literature, revolves around cross-country productivity differences, specifically the fact that labor in affluent countries is more productive due to the adoption of more modern technologies.
The ‘Balassa-Samuelson model’ boils down to this. The wider the variations in wages and prices of services between countries, the larger the gap between purchasing power parity and the equilibrium exchange rate. In terms of purchasing power parity, if international productivity gaps are greater in the production of tradable products than in the production of non-tradable items, the currency of the country with the higher productivity will appear to be overvalued. As a result, the ratio of purchasing power parity to the exchange rate will rise as income rises.1

Is a high PPP beneficial?
As a result, PPP is widely viewed as a more accurate indicator of overall happiness. PPP’s disadvantages include: The most significant disadvantage is that PPP is more difficult to calculate than market-based rates. The ICP is a massive statistical project, and new pricing comparisons are only released seldom.
What is the difference between nominal and PPP GDP?
Macroeconomic parameters are crucial economic indicators, with GDP nominal and GDP PPP being two of the most essential. GDP nominal is the more generally used statistic, but GDP PPP can be utilized for specific decision-making. The main distinction between GDP nominal and GDP PPP is that GDP nominal is the GDP at current market values, whereas GDP PPP is the GDP converted to US dollars using purchasing power parity rates and divided by the total population.
What is the formula for PPP?
The exchange rate of two different currencies in equilibrium is referred to as purchasing power parity. The PPP formula is computed by multiplying the cost of a product or service in one currency by the cost of the same products or services in another currency.
The economic theory that argues that the exchange rate of two currencies will be in equilibrium or at par with the ratio of their respective purchasing powers is known as “purchasing power parity.” By dividing the cost of a given good basket (e.g., good X) in nation 1 in currency 1 by the cost of the same item in country 2 in currency 2, the formula for purchasing power parity of country 1 vs. country 2 may be derived.
Is PPP preferable to nominal?
PPP stands for purchasing power parity, and GDP (PPP) stands for gross domestic product. This article covers a list of countries ranked by their expected GDP prediction (PPP). Countries are sorted based on GDP (PPP) prediction estimates derived from financial and statistical organisations using market or official exchange rates. The information on this page is in international dollars, which is a standardized unit used by economists. If they are different jurisdiction areas or economic entities, several territories that are not usually recognized countries, such as the European Union and Hong Kong, appear on the list.
When comparing the domestic market of a country, PPP comparisons are arguably more useful than nominal GDP comparisons because PPP considers the relative cost of local goods, services, and inflation rates of the country rather than using international market exchange rates, which may distort the real differences in per capita income. It is, however, limited when comparing the quality of similar items between countries and evaluating financial flows between countries. PPP is frequently used to determine global poverty thresholds, and the United Nations uses it to calculate the human development index. In order to estimate a representative basket of all items, surveys like the International Comparison Program include both tradable and non-tradable goods.
The first table shows estimates for 2020 for each of the 194 nations and areas covered by the International Monetary Fund’s (IMF) International Financial Statistics (IFS) database (including Hong Kong and Taiwan). The figures are in millions of dollars and were estimated and released by the International Monetary Fund in April 2020. The second table contains data for 180 of the 193 current United Nations member nations, as well as Hong Kong and Macau, largely for the year 2018. (the two Chinese Special Administrative Regions). The World Bank compiled the data, which is in millions of international dollars. The third table provides a summary of the 2019 CIA World Factbook GDP (PPP) data. The data for GDP at purchasing power parity has also been rebased and projected to 2007 using the latest International Comparison Program price surveys. In cases where they exist in the sources, non-sovereign entities (the world, continents, and some dependent territories) and nations with restricted recognition (such as Kosovo, Palestine, and Taiwan) are included in the list. These economies are not ranked in the graphs, but are instead listed in order of GDP for comparison purposes. Non-sovereign entities are also highlighted in italics.
In the European Single Market, the European Union shares a common market with Iceland, Liechtenstein, Switzerland, and Norway, which ensures the free movement of commodities, capital, services, and labor (the “four freedoms”) among its member states. The EU is also a participant in international trade discussions, and thus may appear on various lists. The EU could be placed above or below the US, depending on the approach used. The World Bank, for example, projects the European Union’s GDP (PPP) to be $20.78 trillion in 2019.
What is the difference between real GDP and purchasing power parity (PPP)?
The nominal gross domestic product is adjusted for inflation to produce real GDP. Some accounting, on the other hand, goes even further, adjusting GDP for the PPP value. This adjustment aims to transform nominal GDP into a value that can be easily compared across nations with various currencies.
What is an example of PPP?
Purchasing power parity (PPP) is an economic theory for determining exchange rates. It stipulates that the pricing levels of two countries should be comparable.
This means that once the currencies have been swapped, commodities in each country will cost the same. According to the PPP hypothesis, if a Coca-Cola costs 100 pence in the UK and $1.50 in the US, the GBP/USD exchange rate should equal 1.50 (the US price divided by the UK price).
However, if you look at the GBP/USD market exchange rate, you’ll notice that it’s closer to 1.25. The disparity arises from the fact that the purchasing power of various currencies differs. There is the true worth of a currency and the notional value, which financial markets trade at, just like any other asset. The purpose of the PPP calculation is to make comparisons between two currencies more relevant by compensating for differences in local buying power.
Global institutions such as the World Bank, the United Nations, the International Monetary Fund, and the European Union also employ PPP measurements.
What is the India PPP?
India’s GDP per capita based on PPP was 6,461 international dollars in 2020. India’s GDP per capita increased from 2,022 international dollars in 2001 to 6,461 international dollars in 2020, expanding at a 6.39 percent annual pace.
How do you compare two countries’ PPPs?
Cupcakes, on the other hand, aren’t exchanged, thus the market exchange rate doesn’t account for the fact that they’re “cheaper” in India. Similarly, in both countries, all non-traded items are not represented in the market exchange rate. As in this situation, it is often assumed that the official exchange rate will understate developing country living standards.
Because developing countries are more likely to attain factors of production, such as lower unit labor costs, non-traded items are often cheaper (the Balassa-Samuelson effect, among others, provides a different explanation regarding the price differential between traded and non-traded goods). It is usually assumed that as a country develops, more items will be exchanged and the difference between the PPP and market exchange rates will narrow.
PPP ratios allow for more accurate comparisons of living levels between countries.
Uses of Purchasing Power Parity
Large disparities in inflation rates around the world make it difficult to compare and quantify the relative outputs of economies and their living standards. Variables based on PPP are in real terms, allowing for comparisons. Based on the most recent estimates, the difference between nominal GDP and PPP-based GDP is depicted in the diagram below.
Because they do not exhibit substantial oscillations in the short run, PPPs serve an important role and are chosen in analyses conducted by politicians, researchers, and private institutions. In the long run, PPPs provide some insight into which way the exchange rate is likely to shift as the economy grows.
Constructing Purchasing Power Parity
A PPP ratio is calculated by taking a weighted average of the prices in both nations for a comparable basket of goods and services consumed by the average citizen in both countries (the weights representing the share of expenditure on each item in total expenditure). The PPP rate of exchange will be used to calculate the price ratio.
To compare living conditions between countries, indexes like the Big Mac Index and the KFC Index use the pricing of a Big Mac burger and a bucket of 12-15 pieces of chicken, respectively. These are fairly standardized products that comprise input costs from a variety of local economic sectors, making them appropriate for comparison.
Reliability of Purchasing Power Parity
PPP ratios, despite their widespread use, may not necessarily reflect a country’s true level of living for the following reasons:
- It’s possible that the underlying expenditure and price levels that represent consumption patterns aren’t accurately recorded.
- It’s difficult to compare diverse countries using identical baskets of products and services since people have varied interests and preferences, and the quality of the items varies.
- Because of trade prohibitions and other trade barriers, prices of traded items are rarely seen as equal, resulting in a departure from PPP.
