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
Economics is the science that studies human behavior in allocating scarce resources to maximize satisfaction, profit, and social welfare.
Scarcity and Choice: The Essence of Economics
Scarcity
Scarcity means a situation where available resources are less than human wants.
Characteristics of Resources
- 1. Scarce – Resources are limited.
- 2. 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.
Unlimited wants + Limited resources = Need for Choice.
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.
Scope
- Demand Theory
- Production Theory
- Price Determination

Macroeconomics
- Derived from Makros (large).
- Studies the economy as a whole.
- Examples: National income, employment, inflation, aggregate demand.
Difference Between Micro and Macro

| 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

4. What is an Economy?
An economy is a system through which people earn their livelihood and satisfy their needs.
Examples: 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.

|---|---|---|
| Income Level | Low | High |
| Wants | Limited | Numerous and complex |
| Interdependence | Low | Very High |
| Exchange | Moderate | Very High |

Economies are classified based on the extent of government control over economic activities.
1. Centrally Planned Economy
- Government controls production and distribution.
- Main aim: Social welfare.
