Definitions of economics
Economics has been defined as the science of wealth (Adam Smith), of welfare (Alfred Marshall), of scarcity and choice (Lionel Robbins) and of growth (Paul Samuelson).
What it means
- Wealth definition: Adam Smith, The Wealth of Nations (1776).
- Welfare definition: Alfred Marshall, Principles of Economics (1890).
- Scarcity definition: Lionel Robbins (1932): human behaviour as a relationship between ends and scarce means with alternative uses.
- Growth definition: Paul Samuelson: choice of scarce resources over time.
- 'Ends and scarce means with alternative uses'
Answer: Lionel Robbins
Related terms

Economic systems
Capitalist economies use the price mechanism, socialist economies use central planning, and mixed economies combine both.
What it means
- Capitalism: private ownership, profit motive, price mechanism decides what, how and for whom.
- Socialism: collective ownership, central planning authority decides.
- Mixed economy: public and private sectors together, markets with regulation; India is an example.
- Public sector railways and banks alongside private companies
Answer: Mixed economy
Related terms
- Price mechanism: allocation of resources by demand and supply
Exam tip: Remember who decides: markets (capitalism), the planner (socialism), both (mixed).
Scarcity, choice and opportunity cost
Because resources are scarce, every choice has an opportunity cost: the value of the next best alternative given up.
What it means
- Scarcity: unlimited wants, limited resources with alternative uses.
- Central problems: what, how and for whom to produce, and providing for growth.
- Opportunity cost counts only the next best alternative, not all alternatives.
- Options: coaching, a ₹800 part-time job, or watching a match
- She chooses coaching; the job was her next best option
Answer: Opportunity cost = ₹800
Related terms
- Production possibility curve: shows the trade-off between two goods
Exam tip: Opportunity cost is about what you give up, not what you pay.
