Introduction to Economics
1. What is Economics?
Economics is the study of how people use scarce resources (wealth) to satisfy their unlimited wants.
Origin of the Word
The word Economics comes from two Greek words:
- Oikos = Household
- Nemein = Management
Together, they mean "Management of Household."
Main Objective of Economics
Since human wants are unlimited and resources are limited, economics helps in:
- Maximizing consumer satisfaction
- Maximizing producer profit
- Maximizing social welfare
Scarcity and Choice: The Essence of Economics
Scarcity
Scarcity means a situation where available resources are less than human wants.
- Scarce – Resources are limited.
- Alternative Uses – A resource can be used in different ways.
Choice
Choice means selecting one option from several alternatives because resources are limited.
Economic Logic
- Scarcity leads to Choice
- Choice leads to Decision-Making
- Decision-making helps achieve maximum satisfaction, profit, and welfare.
2. Microeconomics and Macroeconomics
Microeconomics
- Derived from Mikros (small).
- Studies individual economic units like households, firms, and industries.
- Examples: Demand for a product, price determination.
- Demand Theory
- Production Theory
- Price Determination
- Factor Pricing
Macroeconomics
- Derived from Makros (large).
- Studies the economy as a whole.
- Examples: National income, employment, inflation, aggregate demand.
Difference Between Micro and Macro
| Basis | Microeconomics | Macroeconomics |
|---|---|---|
| Study Level | Individual units | Economy as a whole |
| Concern | Individual prices and output | Aggregate output and price level |
| Assumption | Macro variables constant | Micro variables constant |
| Driving Force | Market forces | Government policies |
3. Positive and Normative Economics
Positive Economics
Studies facts and actual economic conditions.
- Based on facts and data
- Verifiable
- No value judgement
- Deals with "What is" or "What will be"
Normative Economics
Studies opinions and value judgements.
- Based on personal views
- Not verifiable
- Leads to debates
- Deals with "What ought to be"
Difference Between Positive and Normative Economics
| Basis | Positive Economics | Normative Economics |
|---|---|---|
| Focus | Facts and reality | Opinions and ideals |
| Nature | What is | What ought to be |
| Verification | Can be verified | Cannot be verified |
| Value Judgement | No | Yes |
4. What is an Economy?
An economy is a system through which people earn their livelihood and satisfy their needs.
Examples of Economic Activities
Teachers, doctors, farmers, and workers performing different economic activities.
5. Simple Economy vs Complex Economy
People depend on each other because they cannot produce everything themselves.
Simple Economy
An economy with a limited degree of interdependence and exchange.
Difference Between Simple and Complex Economy
| Feature | Simple Economy | Complex Economy |
|---|---|---|
| Income Level | Low | High |
| Wants | Limited | Numerous and complex |
| Interdependence | Low | Very High |
| Exchange | Moderate | Very High |
