Introduction
- Gross Domestic Product (GDP) is a critical economic indicator that measures the total value of goods and services produced within a country’s borders over a specific period.
- GDP serves as a barometer of a nation’s economic health and is used to assess economic growth, productivity, and standards of living.
Current Stats of Indian economy
According to the National Statistical Office (NSO), the real GDP or GDP at constant (2011-12) prices in India for the year 2022-23 is estimated to be ₹160.06 lakh crore, which is approximately $2.15 trillion. The growth rate of real GDP during 2022-23 is estimated at 7.2 percent compared to 9.1 percent in 2021-22. The nominal GDP or GDP at current prices in India for the year 2022-23 is estimated to be ₹272.41 lakh crore, which is approximately $3.67 trillion. The growth rate of nominal GDP during 2022-23 is estimated at 16.1 percent compared to 19.5 percent in 2021-221.
Please note that these estimates are provisional and subject to change as more data becomes available.
“In FY22/23, India’s real GDP expanded at an estimated 6.9 percent. Growth was underpinned by robust domestic demand, strong investment activity bolstered by the government’s push for investment in infrastructure, and buoyant private consumption, particularly among higher income earners.”
GNP, NNP, NDP: Understanding National Income Metrics
Introduction
- Gross National Product (GNP), Net National Product (NNP), and Net Domestic Product (NDP) are economic metrics used to assess a nation’s economic performance.
- They provide insights into the total economic output, accounting for various factors like depreciation, income earned by residents, and domestic production.
Gross National Product (GNP)
- GNP measures the total economic output produced by a country’s residents and businesses, both domestically and abroad, over a specific period.
- It includes income earned from foreign investments and subtracts income sent abroad by foreign workers.
- GNP reflects the overall economic well-being of a country’s citizens, regardless of where they reside.
Net National Product (NNP)
- NNP is GNP adjusted for depreciation (wear and tear) on a country’s capital assets.
- It provides a more accurate picture of the nation’s income available for consumption and investment.
- NNP is useful for assessing long-term economic sustainability and growth.
Net Domestic Product (NDP)
- NDP measures the net economic output produced within a country’s borders over a specific period.
- It accounts for depreciation (capital consumption) and reflects the value of goods and services available for domestic use.
- NDP provides insights into the economic well-being of a country’s residents in terms of domestic production.
Differences Between GNP, NNP, and NDP
Depreciation (Wear and Tear)
- GNP does not account for depreciation, while NNP does by subtracting it.
- NDP, like NNP, also considers depreciation, further refining the measure of available economic output.
Income from Abroad
- GNP includes income earned from abroad and subtracts income sent abroad by foreign workers.
- NNP focuses on income earned by residents, both domestically and abroad.
- NDP concentrates solely on domestic production and income within a country’s borders.
Examples
1. GNP Example
- Imagine an Indian software engineer working in the United States. Her income earned in the U.S. contributes to India’s GNP, even though she’s working abroad.
2. NNP Example
- Consider a factory in India that produces smartphones. To calculate NNP, you would subtract the depreciation of the factory’s machinery from the GNP.
3. NDP Example
- Suppose you want to determine the economic well-being of an Indian state. You would use NDP, considering the depreciation of state-owned infrastructure like roads and bridges.
Best Form of Income Assessment Method
Real GDP and Real NNP
- Real GDP and Real NNP, adjusted for inflation or changes in price levels, provide a more accurate assessment of economic well-being.
- They help evaluate whether growth is due to increased production or merely higher prices.
Factors Influencing the Choice
- The choice between GNP, NNP, and NDP depends on the specific economic analysis and the factors that need consideration.
- For a more comprehensive assessment of a nation’s economic well-being, Real NNP or Real GDP is often preferred.
Associated Concepts of GDP
GDP at Factor Cost (GDPFC)
- GDPFC calculates the total value of goods and services produced within a country before accounting for indirect taxes and subsidies.
- It provides a more accurate reflection of production within the country.
- In India, GDPFC is used to estimate national income.
GDP at Market Prices (GDPM)
- GDPM accounts for indirect taxes (like sales tax and excise duty) and subtracts subsidies from GDPFC.
- It represents the market value of goods and services, including the effect of taxes and subsidies.
- GDPM is often used for policy analysis and fiscal planning.
Nominal GDP
- Nominal GDP is the total value of goods and services produced using current market prices.
- It doesn’t account for inflation or changes in price levels.
- Nominal GDP is useful for comparing economic performance over time but doesn’t provide a true picture of economic growth.
Real GDP
- Real GDP adjusts Nominal GDP for inflation or changes in price levels, allowing for a more accurate measurement of economic growth.
- Real GDP helps evaluate whether growth is due to increased production or merely higher prices.
Base Price and Base Year
Base Price
- The base price is the price level or set of prices used as a reference point for calculating real GDP.
- It represents the price levels prevailing during the chosen base year.
- The base price helps remove the impact of price changes over time when calculating real GDP.
Base Year
- The base year is the specific year selected as a benchmark for measuring changes in economic variables.
- It’s typically chosen to represent a period of economic stability.
- The base year serves as the reference point for calculating real GDP and adjusting for inflation.
The base year for calculating Gross Domestic Product (GDP) in India is chosen to enable inter-year comparisons and to calculate inflation-adjusted growth estimates. The last series changed the base year to 2011-12 from 2004-05. The Ministry of Statistics and Programme Implementation (MOSPI) is considering changing the base year for GDP calculation from 2011-12 to 2017-18.
The base price is the price of goods and services in a particular year, which is used to calculate the value of GDP in that year. The base price for GDP calculation in India is 2011-12.
GDP Calculation Method in India
Current Calculation Method: Production Approach
- India primarily calculates GDP using the production approach, which focuses on the value-added by various sectors of the economy.
- It includes the following steps:
1. Data Collection
- Collection of data from various sectors and economic activities, including agriculture, manufacturing, and services.
2. Gross Value Added (GVA)
- GVA is calculated for each sector, reflecting the total value of goods and services produced within that sector.
- GVA is calculated both at factor cost and at market prices.
Gross Value Added (GVA) is a key indicator for assessing the economic output of different sectors in a country . It measures the value of goods and services produced, excluding taxes and subsidies . GVA is essential for understanding the performance of sectors and their impact on overall economic growth .
In India’s context 🇮🇳, GVA estimation is crucial for evaluating the contributions of sectors like agriculture , manufacturing , construction , and services to the country’s GDP . Policymakers rely on GVA data to make informed decisions about economic policies, resource allocation, and targeted interventions .
For instance, a recent study revealed that India’s core digital economy grew from 5.4% of GVA in 2014 to 8.5% in 2019. This study also emphasized the strong connections between the digital economy and non-digital sectors, showing the ripple effects it has on the overall economy.
In conclusion, GVA is an indispensable metric for assessing economic size and growth , offering valuable insights into sector-wise contributions to GDP and guiding policymakers in shaping effective economic strategies.
3. Factor Income
- Factor income includes wages, rents, interest, and profits earned in each sector.
- It reflects the income generated by the factors of production, such as labor and capital.
4. Net Factor Income from Abroad
- India’s income earned abroad minus foreign income earned in India is determined to calculate Net Factor Income from Abroad.
5. Gross National Income (GNI)
- GNI is calculated by adding Net Factor Income from Abroad to the Factor Income.
- GNI reflects the total income earned by Indian residents, both domestically and abroad.
6. Depreciation Adjustment
- Depreciation (wear and tear) on capital assets is subtracted from GNI to calculate Net National Income (NNI).
7. Indirect Taxes and Subsidies
- Indirect taxes (such as excise duty) and subsidies are added to NNI to calculate Gross Domestic Product at Market Prices (GDPM).
8. Market Price to Factor Cost
- Adjustments are made for indirect taxes and subsidies to calculate GDP at factor cost, providing a closer look at production.
Market price is the final cost at which the manufacturer sells the goods to customers, and it includes all the applicable taxes. Factor cost is the total amount which the manufacturer had to invest in production of a good or commodity, and it doesn’t include any taxes imposed on the final product.
Market Price = Factor Cost + Indirect Taxes – Subsidies.
National income calculated at market price includes taxes and presents a more accurate picture of expenditure and consumption, while national income at factor cost can show the efficiency of each factor of production.
9. Final GDP
- GDP at factor cost is adjusted for depreciation to determine the final GDP.
Challenges in GDP Calculation in India
- Informal Sector: A significant portion of India’s economy operates informally, making data collection challenging.
- Agriculture: Variability in agricultural output due to weather conditions can impact calculations.
- Services Sector: The services sector’s growth poses challenges in accurately measuring output and incomes.
- Unrecorded Transactions: Informal and unrecorded economic activities are often excluded from official calculations.
