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
Definition
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
- 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.
Essence of Economics: 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
- 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.
Features
- Based on facts and data
- Verifiable
- No value judgement
- Deals with "What is" or "What will be"
Normative Economics
Studies opinions and value judgements.
Features
- 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: 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 |
6. Types of Economies
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.
- Public sector dominates.
- Prices decided by the government.
2. Free Market Economy
- Market forces determine production and prices.
- Main aim: Profit maximization.
- Private sector dominates.
- Consumers have complete freedom of choice.
3. Mixed Economy
- Combination of government control and market forces.
- Aim: Profit + Social Welfare.
- Both public and private sectors operate.
- Government regulates essential goods and services.
Comparison of Types of Economies
| Feature | Centrally Planned | Free Market | Mixed Economy |
|---|---|---|---|
| Control | Government | Market Forces | Government + Market |
| Motive | Social Welfare | Profit | Profit + Welfare |
| Consumer Sovereignty | Limited | High | High with Regulation |
| Ownership | Government | Private | Both |
| Price Determination | Government | Market | Market with Regulation |
| Dominant Sector | Public | Private | Public & Private |

Key Points for Revision
1. Core Definition
Economics comes from Oikos (Household) and Nemein (Management). It studies human behavior in allocating scarce resources to maximize satisfaction, profit, and social welfare.
2. The Core Equation
Unlimited Wants + Limited Resources (with Alternative Uses) = Scarcity → Need for Choice → Decision-Making.
3. Micro vs Macro
Micro focuses on individual economic agents (Price Theory, demand/supply of a product). Macro focuses on the aggregate economic system (Income Theory, national income, general price levels, employment).
4. Positive vs Normative
Positive is factual and verifiable ('What is'). Normative is opinion-based and advisory ('What should be').

Very Short Answer Questions (1 Mark)
1. Name the two Greek words from which 'Economics' is derived.
2. Define the term 'Scarcity'.
3. State the main driving force of a Centrally Planned Economy.
4. Give an example of a Microeconomic variable.
5. What is meant by Consumer Sovereignty?
Short Answer Questions (3-4 Marks)
1. Explain the relationship between scarcity and choice.
- Limited Resources: Resources are limited in supply relative to their infinite demands.
- Alternative Uses: Resources can be put to multiple different purposes.
2. Distinguish between Microeconomics and Macroeconomics based on 'Study Level' and 'Driving Force'.
- Study Level: Microeconomics studies economic behavior at an individual level (such as an individual consumer, household, or firm). Macroeconomics studies economic variables at the level of the economy as a whole (such as national income, aggregate demand, and inflation).
- Driving Force: Microeconomics is primarily driven by market forces of demand and supply (the invisible hand). Macroeconomics is heavily influenced by government policy interventions (fiscal policy, monetary policy, etc.).
3. How does a Simple Economy differ from a Complex Economy in terms of interdependence and exchange?
Long Answer Questions (6 Marks)
1. Discuss the three main types of economies, highlighting their features, motives, ownership, and price determination.
1. Centrally Planned Economy:
- Control: Completely controlled by the government or central authority.
- Motive: Social welfare maximization.
- Ownership: Public ownership. Resources are owned and controlled by the state.
- Price Determination: Decided entirely by the government based on planned welfare targets.
2. Free Market Economy:
- Control: Guided entirely by market forces of demand and supply.
- Motive: Profit maximization.
- Ownership: Private ownership. Resources are owned and managed by private individuals or firms.
- Price Determination: Determined automatically by the market mechanism.
3. Mixed Economy:
- Control: Co-existence of both government regulations and market forces.
- Motive: Balances profit maximization (private sector) and social welfare (public sector).
- Ownership: Dual ownership. Both private individuals and the government own resources.
- Price Determination: Determined by market forces, but regulated or administered by the government for essential commodities (like price ceilings on medicines or support prices for farmers).
Case-Based & Competency Questions
Case Study: Price Surge and Vaccine Distribution during a Pandemic
Question: What would happen to social welfare if vaccine distribution was left entirely to private market forces?
Answer: Social welfare would decrease drastically. Private suppliers would price vaccines to maximize profit, rendering them completely unaffordable for low-income populations, leading to incomplete immunization across society.

Explanation: Oikos translates directly to 'Household', and Nemein translates to 'Management' in the Greek language.
Show Correct Answer & Explanation
Explanation: Resources are not only scarce but can also be put to different alternative uses, which makes decision-making necessary.
Show Correct Answer & Explanation
Explanation: 'How to produce' concerns selecting the optimal production technique, such as Labor-Intensive versus Capital-Intensive techniques.
Show Correct Answer & Explanation
Explanation: National Income is an economy-wide variable studied under Macroeconomics.
Show Correct Answer & Explanation
Explanation: Positive economics focuses strictly on objective facts, data, and conditions that can be empirically verified.
Show Correct Answer & Explanation
Explanation: The presence of 'should' indicates a subjective value recommendation, classifying it as Normative.
Assertion & Reason Questions
Options Guide:
- Option A: Both Assertion and Reason are true, and Reason is the correct explanation.
- Option B: Both Assertion and Reason are true, but Reason is NOT the correct explanation.
- Option C: Assertion is true, but Reason is false.
- Option D: Assertion is false, but Reason is true.
Assertion: Scarcity is a universal economic problem applicable to all countries and individuals.
Reason: Even the richest nations and wealthiest individuals have limited resources relative to their unlimited wants.
Show Answer & Analysis
Analysis: Both statements are absolutely true. Scarcity is universal because human desires are infinite, whereas productive resources will always remain finite.
Assertion: Microeconomics is also referred to as Price Theory.
Reason: It focuses heavily on how prices of individual commodities and factors of production are determined.
Show Answer & Analysis
Analysis: Price determination of products and resources represents the primary core of microeconomics, which justifies why it is termed Price Theory.
True or False Exercises
1. If resources did not have alternative uses, the problem of choice would still exist.
2. Macroeconomics studies individual firms and their price decisions.
3. A mixed economy aims to achieve both private profit maximization and social welfare.
Common Mistakes & Exam Tips
Students often think wealthy people or highly developed nations do not face scarcity. Scarcity is a relative concept. No matter how rich a nation is, its collective desires always exceed its productive capacity. Every country must manage a national budget and make trade-offs.
Whenever asked to differentiate between concepts (like Micro vs Macro, or Positive vs Normative), always draw a structured table with a dedicated "Basis of Comparison" column. It makes your answer extremely clear, precise, and easily earnable of full marks.
