Gross domestic product, also known as GDP, is among the most common measures of economic activity. Governments, central banks, and business organizations often cite it in newspapers, on TV, and in reports. A wide range of national and global economies use it as a reference point. Generally, businesses and workers are better off when GDP grows, especially if inflation does not pose a problem.
What is GDP?
In economic terms, GDP is the sum of all items sold in the market during a specified period that compose the country’s economy. GDP refers to the final value of a good or service that has been produced in a country in a given period of time. The period can either be a quarter or a year. Economic activity and output are measured using the GDP worldwide.
GDP measures the total monetary value or market value of all the goods and services produced within the borders of a country. It is a comprehensive measure of a country’s economic health because it provides a broad picture of its overall domestic production.
The GDP is generally calculated annually, but sometimes it is calculated quarterly as well. For example, the U.S. government releases annualized GDP estimates every quarter and every year. As this report includes real-term data sets, the data is adjusted for inflation and adjusted for price changes.
Types of GDP
Let us now talk about different types of GDPs which are commonly used in an economy:
Nominal GDP
Statistically, nominal GDP measures the amount of economic production for an economy considering current prices. It is used to compare output within a year in terms of different quarters of the same year. Nominal GDP is calculated by valuing all goods and services at the prices they sell for in the given year. Real GDP is used when comparing two years’ GDP.
Real GDP
It is a macroeconomic statistic that measures the impact of inflation or deflation on the trend in output over time by adjusting the value of GDP for inflation. Real GDP measures the total value of goods and services produced in a given year and is adjusted for inflation.
GDP is affected by inflation since goods and services are valued in money. A price increase tends to increase a country’s GDP, even when the quantity of goods produced remains the same.
GDP Per Capita
A country’s GDP per capita measures its GDP per person. It states that the income or output per person in an economy is a good indicator of average productivity and living standards. It is possible to express GDP per capita in nominal terms, real terms, or PPP terms. As a measure of economic production value, per-capita GDP shows how much each individual contributes to economic production.
GDP Growth Rate
Economic growth is measured by a country’s GDP growth rate, which compares its growth from year to year (or quarter to quarter). Inflation and unemployment rates are among the key policy targets used to measure the growth rate of GDP. The GDP growth is usually expressed in percentage.
GDP Purchasing Power Parity
In economics, purchasing power parity (PPP) is a method used by economists to compare the economic productivity and standards of living in different countries. When GDP is measured in purchasing power parity, it measures the volume of GDP for different countries or regions in international dollars, even though it is not directly a measure of GDP. It is calculated by dividing GDP by the corresponding PPP. To compare real outputs, real incomes, and living standards across countries, the method adjusts for differences in local prices and costs of living.
Nominal vs Real GDP
Compared to nominal GDP, real gross domestic product (GDP) more accurately reflects an economy’s output. Economists can use real GDP to measure a country’s annual growth or contraction by eliminating distortions caused by inflation or deflation or fluctuations in currency rates.
A simple explanation for why real GDP is the most accurate way to measure national economic performance can be provided.
Imagine, for instance, a hypothetical country whose nominal GDP has increased from $100 billion in 2000 to $150 billion in 2010. As a result of inflation, the local currency’s relative value decreased by 50% over the same period.
In terms of nominal GDP alone, the economy has grown by 50% over the past decade. It would, however, be $75 billion if the GDP was expressed in 2000 dollars.
Why GDP is important
A financial system is an indicator of its size, performance, and widespread fitness for all its stakeholders, consisting of traders, politicians, and citizens. GDP is an important dimension of an economy. GDP is calculated on an annual as well as quarterly basis. The Central Statistics Office, which comes under the Ministry of Statistics and Program, calculates GDP using statistics accumulated from across the nation.
If the GDP number is developing, then the economic system has ended up being more efficient. If the GDP is shrinking, then the economy has ended up much less productive. This assessment may be especially insightful when performed over an extended duration, as it allows long-term developments to emerge.
The metric can be utilized in several approaches, making it an invaluable tool:
- A corporation or firm looking to amplify into new markets might use GDP to evaluate which markets are the healthiest.
- An investor interested in rising markets might look at GDP to apprehend which nations are growing at the quickest quotes and, consequently, would possibly provide the greatest return on investment (ROI).
- A policymaker may use GDP to understand how guidelines have impacted the economy.
How To Calculate GDP
There are three main ways to calculate the GDP. If calculated properly, the results from all three methods should be the same.
- The Expenditure Approach
The expenditure approach, also referred to as the spending approach, determines how much is spent by the various economic groups. The following formula can be used to calculate GDP through this approach:
GDP = C + G + I + NX
In which,
- C = consumption;
- G = government expenditure;
- I = investment; and
- NX = net exports
All of these factors contribute to the GDP of a country.
- The Income Approach
The income approach determines the income generated by each factor of production in an economy, including labor’s wages, land’s rent, capital’s return in the form of interest, and businesses’ profits.
GDP = Total National Income + Sales Taxes + Depreciation + Net Foreign Factor Income
- The Production Approach
The production approach is the opposite of the expenditure approach. The production approach estimates the total value of economic output and subtracts the cost of intermediate goods that are consumed in the process rather than measuring the input costs that go into economic activity.
Wrap Up
GDP isn’t always a degree of the overall widespread development of an economy. However, changes within the output of products and offerings per person are often be used as a degree of whether the average citizen in a country is doing better or worse. The best economies also rely on the distribution of GDP to calculate the growth and development of their economy.
