GDP quantifies the monetary worth of final goods and services produced in a country over a specific period of time, i.e. those that are purchased by the end user (say a quarter or a year). It is a metric that measures all of the output produced within a country’s borders.
In basic terms, what is GDP in economics?
The total monetary or market worth of all finished goods and services produced inside a country’s borders in a certain time period is known as GDP. It serves as a comprehensive scorecard of a country’s economic health because it is a wide measure of entire domestic production.
Explain GDP using an example.
The Gross Domestic Product (GDP) is a metric that measures the worth of a country’s economic activities. GDP is the sum of the market values, or prices, of all final goods and services produced in an economy during a given time period. Within this seemingly basic concept, however, there are three key distinctions:
- GDP is a metric that measures the value of a country’s output in local currency.
- GDP attempts to capture all final commodities and services generated within a country, ensuring that the final monetary value of everything produced in that country is represented in the GDP.
- GDP is determined over a set time period, usually a year or quarter of a year.
Computing GDP
Let’s look at how to calculate GDP now that we know what it is. GDP is the monetary value of all the goods and services generated in an economy, as we all know. Consider Country B, which exclusively produces bananas and backrubs. In the first year, they produce 5 bananas for $1 each and 5 backrubs worth $6 each. This year’s GDP is (quantity of bananas X price of bananas) + (quantity of backrubs X price of backrubs), or (5 X $1) + (5 X $6) = $35 for the country. The equation grows longer as more commodities and services are created. For every good and service produced within the country, GDP = (quantity of A X price of A) + (quantity of B X price of B) + (quantity of whatever X price of whatever).
To compute GDP in the real world, the market values of many products and services must be calculated.
While GDP’s total output is essential, the breakdown of that output into the economy’s big structures is often just as important.
In general, macroeconomists utilize a set of categories to break down an economy into its key components; in this case, GDP is equal to the total of consumer spending, investment, government purchases, and net exports, as represented by the equation:
- The sum of household expenditures on durable commodities, nondurable items, and services is known as consumer spending, or C. Clothing, food, and health care are just a few examples.
- The sum of spending on capital equipment, inventories, and structures is referred to as investment (I).
- Machinery, unsold items, and homes are just a few examples.
- G stands for government spending, which is the total amount of money spent on products and services by all government agencies.
- Naval ships and government employee wages are two examples.
- Net exports, or NX, is the difference between foreigners’ spending on local goods and domestic residents’ expenditure on foreign goods.
- Net exports, to put it another way, is the difference between exports and imports.
GDP vs. GNP
GDP is just one technique to measure an economy’s overall output. Another technique is to calculate the Gross National Product, or GNP. As previously stated, GDP is the total value of all products and services generated in a country. GNP narrows the definition slightly: it is the total value of all goods and services generated by permanent residents of a country, regardless of where they are located. The important distinction between GDP and GNP is based on how production is counted by foreigners in a country vs nationals outside of that country. Output by foreigners within a country is counted in the GDP of that country, whereas production by nationals outside of that country is not. Production by foreigners within a country is not considered for GNP, while production by nationals from outside the country is. GNP, on the other hand, is the value of goods and services produced by citizens of a country, whereas GDP is the value of goods and services produced by a country’s citizens.
For example, in Country B (shown in ), nationals produce bananas while foreigners produce backrubs.
Figure 1 shows that Country B’s GDP in year one is (5 X $1) + (5 X $6) = $35.
Because the $30 from backrubs is added to the GNP of the immigrants’ home country, the GNP of country B is (5 X $1) = $5.
The distinction between GDP and GNP is theoretically significant, although it is rarely relevant in practice.
GDP and GNP are usually quite close together because the majority of production within a country is done by its own citizens.
Macroeconomists use GDP as a measure of a country’s total output in general.
Growth Rate of GDP
GDP is a great way to compare the economy at two different times in time. This comparison can then be used to calculate a country’s overall output growth rate.
Subtract 1 from the amount obtained by dividing the GDP for the first year by the GDP for the second year to arrive at the GDP growth rate.
This technique of calculating total output growth has an obvious flaw: both increases in the price of products produced and increases in the quantity of goods produced result in increases in GDP.
As a result, determining whether the volume of output is changing or the price of output is changing from the GDP growth rate is challenging.
Because of this constraint, an increase in GDP does not always suggest that an economy is increasing.
For example, if Country B produced 5 bananas value $1 each and 5 backrubs of $6 each in a year, the GDP would be $35.
If the price of bananas rises to $2 next year and the quantity produced remains constant, Country B’s GDP will be $40.
While the market value of Country B’s goods and services increased, the quantity of goods and services produced remained unchanged.
Because fluctuations in GDP are not always related to economic growth, this factor can make comparing GDP from one year to the next problematic.
Real GDP vs. Nominal GDP
Macroeconomists devised two types of GDP, nominal GDP and real GDP, to deal with the uncertainty inherent in GDP growth rates.
- The total worth of all produced goods and services at current prices is known as nominal GDP. This is the GDP that was discussed in the previous parts. When comparing sheer output with time rather than the value of output, nominal GDP is more informative than real GDP.
- The total worth of all produced goods and services at constant prices is known as real GDP.
- The prices used to calculate real GDP are derived from a certain base year.
- It is possible to compare economic growth from one year to the next in terms of production of goods and services rather than the market value of these products and services by leaving prices constant in the computation of real GDP.
- In this way, real GDP removes the effects of price fluctuations from year-to-year output comparisons.
Choosing a base year is the first step in computing real GDP. Use the GDP equation with year 3 numbers and year 1 prices to calculate real GDP in year 3 using year 1 as the base year. Real GDP equals (10 X $1) + (9 X $6) = $64 in this situation. The nominal GDP in year three is (10 X $2) + (9 X $6) = $74 in comparison. Because the price of bananas climbed from year one to year three, nominal GDP grew faster than actual GDP during this period.
GDP Deflator
Nominal GDP and real GDP convey various aspects of the shift when comparing GDP between years. Nominal GDP takes into account both quantity and price changes. Real GDP, on the other hand, just measures changes in quantity and is unaffected by price fluctuations. Because of this distinction, a third relevant statistic can be calculated once nominal and real GDP have been computed. The GDP deflator is the nominal GDP to real GDP ratio minus one for a particular year. The GDP deflator, in effect, shows how much of the change in GDP from a base year is due to changes in the price level.
Let’s say we want to calculate the GDP deflator for Country B in year 3 using as the base year.
To calculate the GDP deflator, we must first calculate both nominal and real GDP in year 3.
By rearranging the elements in the GDP deflator equation, nominal GDP may be calculated by multiplying real GDP and the GDP deflator.
This equation displays the distinct information provided by each of these output measures.
Changes in quantity are captured by real GDP.
Changes in the price level are captured by the GDP deflator.
Nominal GDP takes into account both price and quantity changes.
You can break down a change in GDP into its component changes in price level and change in quantities produced using nominal GDP, real GDP, and the GDP deflator.
GDP Per Capita
When describing the size and growth of a country’s economy, GDP is the single most helpful number. However, it’s crucial to think about how GDP relates to living standards. After all, a country’s economy is less essential to its residents than the level of living it delivers.
GDP per capita, calculated by dividing GDP by the population size, represents the average amount of GDP received by each individual, and hence serves as an excellent indicator of an economy’s level of life.
The value of GDP per capita is the income of a representative individual because GDP equals national income.
This figure is directly proportional to one’s standard of living.
In general, the higher a country’s GDP per capita, the higher its level of living.
Because of the differences in population between countries, GDP per capita is a more relevant indicator for measuring level of living than GDP.
If a country has a high GDP but a large population, each citizen may have a low income and so live in deplorable circumstances.
A country, on the other hand, may have a moderate GDP but a small population, resulting in a high individual income.
By comparing standard of living among countries using GDP per capita, the problem of GDP division among a country’s residents is avoided.
What is GDP and what does it mean?
- It indicates the total value of all commodities and services produced inside a country’s borders over a given time period.
- Economists can use GDP to evaluate if a country’s economy is expanding or contracting.
- GDP can be used by investors to make investment decisions; a weak economy means lower earnings and stock values.
What is the best way to explain GDP to a child?
The gross domestic product, or GDP, is a metric used to assess a country’s economic health. It refers to the entire value of goods and services produced in a country over a given time period, usually a year. The gross domestic product (GDP) is the most widely used indicator of output and economic activity in the world.
Each country’s GDP data is prepared and published on a regular basis. Furthermore, international agencies like the World Bank and the International Monetary Fund publish and retain historical GDP data for many nations on a regular basis. The Bureau of Economic Analysis of the US Department of Commerce publishes GDP data quarterly in the United States.
An economy is regarded to be in expansion when it grows at a positive rate for several quarters in a row (also called economic boom). The economy is generally regarded to be in a recession when it experiences two or more consecutive quarters of negative GDP growth (also called economic bust). GDP per capita (also known as GDP per person) is a measure of a country’s living standard. In economic terms, a country with a greater GDP per capita is considered to be better off than one with a lower level.
Gross domestic product (GDP) is different from gross national product (GNP), which comprises all goods and services generated by a country’s citizens, whether they are produced in the country or outside. GDP replaced GNP as the primary indicator of economic activity in the United States in 1991. GDP was more consistent with the government’s other measurements of economic output and employment because it only covered domestic production. (Also see economics.)
In 2021, what would India’s GDP be?
In its second advance estimates of national accounts released on Monday, the National Statistical Office (NSO) forecasted the country’s growth for 2021-22 at 8.9%, slightly lower than the 9.2% estimated in its first advance estimates released in January.
Furthermore, the National Statistics Office (NSO) reduced its estimates of GDP contraction for the coronavirus pandemic-affected last fiscal year (2020-21) to 6.6 percent. The previous projection was for a 7.3% decrease.
In April-June 2020, the Indian economy contracted 23.8 percent, and in July-September 2020, it contracted 6.6 percent.
“While an adverse base was expected to flatten growth in Q3 FY2022, the NSO’s initial estimates are far below our expectations (6.2 percent for GDP), with a marginal increase in manufacturing and a contraction in construction that is surprising given the heavy rains in the southern states,” said Aditi Nayar, Chief Economist at ICRA.
“GDP at constant (2011-12) prices is estimated at Rs 38.22 trillion in Q3 of 2021-22, up from Rs 36.26 trillion in Q3 of 2020-21, indicating an increase of 5.4 percent,” according to an official release.
According to the announcement, real GDP (GDP) or Gross Domestic Product (GDP) at constant (2011-12) prices is expected to reach Rs 147.72 trillion in 2021-22, up from Rs 135.58 trillion in the first updated estimate announced on January 31, 2022.
GDP growth is expected to be 8.9% in 2021-22, compared to a decline of 6.6 percent in 2020-21.
In terms of value, GDP in October-December 2021-22 was Rs 38,22,159 crore, up from Rs 36,22,220 crore in the same period of 2020-21.
According to NSO data, the manufacturing sector’s Gross Value Added (GVA) growth remained nearly steady at 0.2 percent in the third quarter of 2021-22, compared to 8.4 percent a year ago.
GVA growth in the farm sector was weak in the third quarter, at 2.6 percent, compared to 4.1 percent a year before.
GVA in the construction sector decreased by 2.8%, compared to 6.6% rise a year ago.
The electricity, gas, water supply, and other utility services segment grew by 3.7 percent in the third quarter of current fiscal year, compared to 1.5 percent growth the previous year.
Similarly, trade, hotel, transportation, communication, and broadcasting services expanded by 6.1 percent, compared to a decline of 10.1 percent a year ago.
In Q3 FY22, financial, real estate, and professional services growth was 4.6 percent, compared to 10.3 percent in Q3 FY21.
During the quarter under examination, public administration, defense, and other services expanded by 16.8%, compared to a decrease of 2.9 percent a year earlier.
Meanwhile, China’s economy grew by 4% between October and December of 2021.
“India’s GDP growth for Q3FY22 was a touch lower than our forecast of 5.7 percent, as the manufacturing sector grew slowly and the construction industry experienced unanticipated de-growth.” We have, however, decisively emerged from the pandemic recession, with all sectors of the economy showing signs of recovery.
“Going ahead, unlock trade will help growth in Q4FY22, as most governments have eliminated pandemic-related limitations, but weak rural demand and geopolitical shock from the Russia-Ukraine conflict may impair global growth and supply chains.” The impending pass-through of higher oil and gas costs could affect domestic demand mood, according to Elara Capital economist Garima Kapoor.
“Strong growth in the services sector and a pick-up in private final consumption expenditure drove India’s real GDP growth to 5.4 percent in Q3.” While agriculture’s growth slowed in Q3, the construction sector’s growth became negative.
“On the plus side, actual expenditure levels in both the private and public sectors are greater than they were before the pandemic.
“Given the encouraging trends in government revenues and spending until January 2022, as well as the upward revision in the nominal GDP growth rate for FY22, the fiscal deficit to GDP ratio for FY22 may come out better than what the (federal) budget projected,” said Rupa Rege Nitsure, group chief economist, L&T Financial Holdings.
“The growth number is pretty disappointing,” Sujan Hajra, chief economist of Mumbai-based Anand Rathi Securities, said, citing weaker rural consumer demand and investments as reasons.
After crude prices soared beyond $100 a barrel, India, which imports virtually all of its oil, might face a wider trade imbalance, a weaker rupee, and greater inflation, with a knock to GDP considered as the main concern.
“We believe the fiscal and monetary policy accommodation will remain, given the geopolitical volatility and crude oil prices,” Hajra added.
According to Nomura, a 10% increase in oil prices would shave 0.2 percentage points off India’s GDP growth while adding 0.3 to 0.4 percentage points to retail inflation.
Widening sanctions against Russia are likely to have a ripple impact on India, according to Sakshi Gupta, senior economist at HDFC Bank.
“We see a 20-30 basis point downside risk to our base predictions,” she said. For the time being, HDFC expects the GDP to rise 8.2% in the coming fiscal year.
Who determines GDP?
To collect and compile the data needed to calculate the GDP and other statistics, the Central Statistics Office collaborates with numerous federal and state government agencies and departments. The Price Monitoring Cell at the Ministry of Consumer Affairs, for example, collects and calibrates data points pertaining to manufacturing, crop yields, and commodities, which are used to calculate the Wholesale Price Index (WPI) and the Consumer Price Index (CPI).
What is the formula for GDP?
Gross domestic product (GDP) equals private consumption + gross private investment + government investment + government spending + (exports Minus imports).
GDP is usually computed using international standards by the country’s official statistical agency. GDP is calculated in the United States by the Bureau of Economic Analysis, which is part of the Commerce Department. The System of National Accounts, compiled in 1993 by the International Monetary Fund (IMF), the European Commission, and the Organization for Economic Cooperation and Development (OECD), is the international standard for estimating GDP.
Is GDP calculated per capita?
The Gross Domestic Product (GDP) per capita is calculated by dividing a country’s GDP by its total population. The table below ranks countries throughout the world by GDP per capita in Purchasing Power Parity (PPP), as well as nominal GDP per capita. Rather to relying solely on exchange rates, PPP considers the relative cost of living, offering a more realistic depiction of real income disparities.
What’s the distinction between GDP and GNP?
- Both the gross domestic product (GDP) and the gross national product (GNP) are widely used indicators of a country’s total economic output.
- The value of goods and services generated within a country’s borders, by citizens and non-citizens equally, is measured by GDP.
- The value of goods and services produced by a country’s population, both locally and internationally, is measured by GNP.
- The most often utilized metric by global economies is GDP. In 1991, the United States stopped using GNP and instead used GDP to compare itself to other economies.
