Economics: Meaning, Scope, Basic Concepts, and the Indian Economy Before and After Independence
This unit opens the BSEB Matric Social Science (Economics) paper and rewards exact definitions, the micro/macro and positive/normative distinctions, the central problems of an economy, and the contrast between the colonial economy of 1947 and the planned, liberalised economy after independence.
Definitions you must be able to attribute
- Adam Smith (1776, Wealth of Nations): economics is the science of wealth.
- Alfred Marshall: economics studies material welfare, 'the ordinary business of life'.
- Lionel Robbins (1932): the science studying human behaviour as a relationship between scarce ends and means having alternative uses - a science of choice.
- Paul Samuelson: growth definition, stressing choice over time.
Scope and basic concepts
Microeconomics studies a single unit - one household, one firm, the price of one good. Macroeconomics studies aggregates - national income, the general price level, unemployment. Positive statements are verifiable facts; normative statements are opinions and cannot be proved. Every economy answers three questions: what to produce, how to produce, for whom to produce. Opportunity cost is the next best alternative forgone.
1947 and after
Colonial India had about two-thirds of its workforce in agriculture, was deindustrialised by British machine-made imports, suffered the drain of wealth (Dadabhai Naoroji), and carried zamindari with insecure tenancy, literacy near 16 per cent and life expectancy around 32 years. After 1947 came five-year plans, land reform and public-sector heavy industry; the 1991 reforms (liberalisation, privatisation, globalisation) enlarged the role of markets.
Worked example
GDP is ₹100 lakh crore with a population of 100 crore, so per capita income is ₹1,00,000. Next year GDP is ₹105 lakh crore and population 105 crore, so per capita income is again ₹1,00,000. Reasoning: output grew exactly as fast as population, so the average living standard did not change - which is why comparisons use per capita income and distribution, not GDP alone.
Traps that cost marks
Mixing Robbins (choice) with Marshall (welfare); labelling an opinion as a positive statement; calling national income a micro concept.
