This chapter explains the basic concepts of macroeconomics and the methods used to measure national income. It shows how circular flows link production, income, and expenditure, and distinguishes between nominal income, real income, and economic welfare. Source: NCERT Introductory Macroeconomics (Reprint 2026-27) , Chapter 2, National Income Accounting Final goods are meant for final consumption or capital formation and undergo no further transformation within the production boundary. Intermediate goods are used up as raw materials or resold during the year. Capital goods are durable producer goods like machinery that assist production over many years. In a simple two-sector economy of households and firms, households supply factor services and receive factor payments. Firms produce goods and services which households purchase with their income, making aggregate production equal to aggregate income and aggregate expenditure. Gross value added by a firm is the value of its total output minus the intermediate goods consumed. Summing the gross value added across all producing units in the domestic territory gives gross domestic product at market prices, avoiding the error of double counting. The income method sums factor payments, which comprise compensation of employees, rent, interest, and profits, along with mixed income. The expenditure method sums final consumption expenditure of households and government, gross domestic capital formation, and net exports. Gross domestic product can be adjusted for consumption of fixed capital to get net domestic product, and adjusted for net factor income from abroad to get national product. Market prices include net indirect taxes, which are subtracted to arrive at factor cost. Nominal GDP measures output at current prices, while real GDP evaluates output at constant base year prices to remove the effect of inflation. The GDP deflator is the ratio of nominal GDP to real GDP. GDP is an imperfect indicator of welfare because it does not reflect the distribution of income, leaves out non-monetary exchanges like domestic labour, and ignores positive or negative externalities like environmental pollution.

Value of output = Sales + Change in inventory = 800 + 100 = ₹900 GVA = Value of output - Intermediate consumption = 900 - 450 = ₹450 ₹450 NNP at market prices = GDP at market prices - Consumption of fixed capital + NFIA = 1,200 - 150 + (-20) = ₹1,030 NNP at factor cost = NNP at market prices - Net indirect taxes = 1,030 - 100 = ₹930 ₹930 GDP deflator = (Nominal GDP / Real GDP) × 100 120 = (8,400 / Real GDP) × 100 Real GDP = (8,400 × 100) / 120 = ₹7,000 ₹7,000 Money and Banking .

Start free to see how it works. - Ch 2 NCERT book - 80 marks, theory paper - 3 quick checks - Adding intermediate consumption to final output when calculating GDP . Always subtract intermediate consumption from total value of output to avoid the problem of double counting. - Including transfer payments in national income calculations . Include only factor payments earned by rendering factor services. Exclude unilateral transfers like old age pensions, gifts, and scholarships. - Adding net indirect taxes when converting from market prices to factor cost . Factor cost represents payments to producers before taxes and subsidies. Subtract net indirect taxes from market price to obtain factor cost. - Treating real GDP growth and welfare improvement as identical . A rise in real GDP does not guarantee higher welfare if income distribution becomes unequal or if negative externalities like pollution increase. ## Key Links - [CBSE](https://www.swavid.com/cbse) - [Class 12](https://www.swavid.com/cbse/class-12) - [Economics](https://www.swavid.com/cbse/class-12/economics/chapters) - [Start free →](https://www.swavid.com/signup) - [All 13 chapters](https://www.swavid.com/cbse/class-12/economics/chapters) - [NCERT Introductory Macroeconomics (Reprint 2026-27)](https://ncert.nic.in/textbook.php) - [Open notes](https://www.swavid.com/cbse/class-12/economics/chapter/money-and-banking) - [Open notes](https://www.swavid.com/cbse/class-12/economics/chapter/macroeconomics-introduction) - [Open notes](https://www.swavid.com/cbse/class-12/economics/chapter/determination-of-income-and-employment) - [Class 12 Economics](https://www.swavid.com/cbse/class-12/economics/chapters) - [Start free →](https://www.swavid.com/signup)
