Economics studies how individuals and societies allocate scarce resources to
satisfy unlimited wants.
2. Three Major Views of Economics
(a) Wealth View – Adam Smith
• Focus: Wealth creation and accumulation
• Defined economics as the science of wealth
• Criticism: Ignores human welfare
(b) Welfare View – Alfred Marshall
• Focus: Human welfare
• Economics studies wealth and its impact on well-being
• More humane approach than wealth view
(c) Scarcity View – Lionel Robbins
• Focus: Scarcity and choice
• Economics: “Study of human behavior as a relationship between ends and
scarce means with alternative uses”
• Most accepted modern definition
3. Positive vs Normative Economics
Positive Economics
• Based on facts and data
• Example: “Inflation is 6%”
Normative Economics

,4. Business Economics
Definition
Application of economic theory to business decision-making.
Scope
• Demand analysis
• Cost and production
• Pricing decisions
• Profit management
Importance
• Helps in decision making
• Improves resource allocation
• Reduces uncertainty
📊 Key Economic Concepts
5. Production Possibility Frontier (PPF)
• Shows maximum output combinations of two goods
• Assumes limited resources
Key Points:
• Downward sloping
• Opportunity cost increases
6. Opportunity Cost
• Cost of the next best alternative foregone
Example: Choosing study over watching TV → TV time is opportunity cost
7. Time and Discounting Principles
• Future money is worth less than present money
• Uses discounting
Example: ₹100 today > ₹100 next year
, 8. Accounting Profit vs Economic Profit
Type Meaning
Accounting Profit Revenue – Explicit Cost
Economic Profit Revenue – (Explicit + Implicit Cost)
9. Incremental and Marginal Concepts
Incremental Concept
• Change due to a decision
Marginal Concept
• Change per unit
Example:
• Marginal Cost = Cost of producing one extra unit
10. Concept of Efficiency
Types:
• Productive Efficiency (minimum cost)
• Allocative Efficiency (optimal resource use)
Business Cycle
Meaning
Fluctuations in economic activity over time
Phases:
1. Expansion
2. Boom
