ECA01 — National Income

GNP = GDP + NFIA (Net Factor Income from Abroad). NFIA = income earned by Indian nationals abroad minus income earned by foreigners in India. GNP captures national output regardless of location; GDP captures territorial output regardless of nationality. NNP = GNP − Depreciation.

Per Capita Income = National Income ÷ Total Population. It measures average income per person and is used to compare living standards internationally. India has a high total GDP but lower per capita income due to its large population (~1.4 billion).

GDP (Gross Domestic Product) = market value of all final goods and services produced within a country's territory in a given year, regardless of the nationality of producers. 'Final' goods avoid double counting of intermediate goods.

NNP at factor cost = NNP at market price − Net Indirect Taxes (indirect taxes minus subsidies). This is also called National Income. Factor cost = market price − indirect taxes + subsidies. It represents income paid to factors of production.

Resale of used goods (like second-hand cars) is NOT included in GDP because those goods were counted in GDP when first produced. Only new production in the current year is included. GDP counts current production — not transfers of ownership of existing goods.

The Value Added Method sums the value added (output minus intermediate inputs) at each stage of production. This avoids double counting. Value Added = Output − Intermediate Consumption. Sum of all value added across all sectors = GDP at factor cost.

Real GDP = Nominal GDP adjusted for inflation using a price deflator (base year prices). Nominal GDP is valued at current prices; Real GDP removes the effect of price changes and reflects actual change in output. GDP Deflator = (Nominal GDP / Real GDP) × 100.

The Services sector (tertiary sector) contributes approximately 55–57% of India's GDP — the largest share. Agriculture contributes ~15–17%, and Industry (manufacturing, mining, construction) contributes ~25–28%. India is called a service-led economy.

Depreciation (also called Capital Consumption Allowance) = wear and tear or reduction in value of capital assets (machinery, buildings, equipment) used in production. NNP = GNP − Depreciation. It represents the amount of capital that must be replaced to maintain productive capacity.

Transfer payments (pensions, unemployment benefits, scholarships) are excluded from National Income because they involve no corresponding production of goods or services — money is simply transferred from one party to another without creating new output. Including them would cause double counting.

The Income Approach (Factor Income Method) sums all factor incomes: wages (labour), rent (land), interest (capital), and profit (entrepreneurship) earned in production. This equals National Income at factor cost. All three approaches — output, income, expenditure — should give the same GDP.

GDP Deflator = (Nominal GDP / Real GDP) × 100. It measures the overall price level of an economy. To get Real GDP: Real GDP = (Nominal GDP / GDP Deflator) × 100. Unlike CPI, GDP Deflator covers ALL goods and services in the economy, not just a consumer basket.

National Income is a flow concept — it is measured over a period of time (usually one year). Stock concepts are measured at a point in time (e.g., money supply, wealth, foreign exchange reserves). GDP, investment, savings, and exports are all flow variables.

India's National Income is estimated by the Central Statistics Office (CSO), now part of the National Statistical Office (NSO) under the Ministry of Statistics and Programme Implementation (MoSPI). The RBI handles monetary data; NSO handles GDP and national accounts data.

Green GDP = conventional GDP − cost of environmental degradation (pollution, resource depletion, ecosystem damage). It gives a more accurate measure of sustainable economic growth. Conventional GDP ignores the depletion of natural capital, which Green GDP attempts to account for.

OMO: RBI buys/sells government securities. Buying securities → money supply increases → lower interest rates → more investment → higher output (National Income rises). Selling securities → reverse effect. This is an indirect monetary policy tool affecting income through investment.

India's current GDP series uses 2011–12 as the base year (adopted in January 2015 when the new GDP series was released). The previous base year was 2004–05. The base year is used to measure Real GDP by eliminating the effect of price changes.

HDI is published annually by the UNDP in the Human Development Report. HDI combines three dimensions: Life Expectancy (health), Education (mean and expected years of schooling), and GNI per capita (standard of living). It was developed by Mahbub ul Haq and Amartya Sen.

National Income = NNP at factor cost = Net National Income. It equals: GNP − Depreciation − Net Indirect Taxes. This represents the actual earnings of factors of production (land, labour, capital, enterprise) before any redistributive transfers.

GDP counts output produced within India's territory — regardless of nationality. An Indian working in the USA produces output outside India's territory, so it is NOT in India's GDP (but IS in India's GNP). The foreign company in Mumbai produces within India → counted in India's GDP.
