Introduction & Overview
Economics is a social science concerned with the production, distribution, and consumption of goods and services. It studies how individuals, businesses, governments, and societies make decisions about allocating scarce resources to satisfy their unlimited wants. An economy refers to the complex system of interrelated production, consumption, and exchange activities that ultimately determines how resources are allocated among all the participants. Understanding these fundamental concepts is crucial for analyzing economic policies, national income, and the overall functioning of a country's economic landscape. This module introduces the core building blocks of economic thought, different economic systems, and the basic challenges every economy faces.

1.1.1. Basic Concepts & Scarcity
Scarcity
Scarcity is the fundamental economic problem of having seemingly unlimited human wants and needs in a world of limited resources. It states that society has insufficient productive resources to fulfill all human wants and needs. It is universal, affecting all individuals and societies, rich or poor, and necessitates choice.
(NCERT Class 11 Microeconomics, Chapter 1)
Choice
Since resources are scarce, individuals and societies must make choices among alternatives. For example, an individual may choose between buying a book or a meal; a society may choose between funding healthcare or defense. Economic decision-making is essentially the process of making choices.
Opportunity Cost
The opportunity cost of a chosen alternative is the value of the next best alternative foregone. It represents the real sacrifice involved in making a decision. Example: If a government decides to build a highway, the opportunity cost could be the hospital or school that could have been built with the same resources.
(NCERT Class 11 Microeconomics, Chapter 1)
Production Possibility Frontier (PPF)
The PPF (also called Production Possibility Curve) is a graphical representation showing all the different combinations of two goods that can be produced with given resources and technology, assuming full and efficient utilization of these resources.
Characteristics of PPF:
- Downward Sloping: To produce more of one good, some units of the other good must be sacrificed (due to scarcity).
- Concave to the Origin: This shape reflects the increasing marginal opportunity cost. As we produce more and more of one good, the opportunity cost (in terms of the other good sacrificed) tends to increase. This is because resources are not equally efficient in the production of all goods.
Points on the PPF:
- On the PPF (e.g., Point C): Represent efficient utilization of resources.
- Inside the PPF (e.g., Point B): Represent inefficient utilization or underutilization of resources.
- Outside the PPF (e.g., Point A): Represent unattainable combinations with current resources and technology.
Shifts in PPF:
- Rightward Shift (Outward): Indicates economic growth due to an increase in resources (e.g., labor, capital) or technological advancement.
- Leftward Shift (Inward): Indicates a decrease in productive capacity, perhaps due to natural disasters, war, or resource depletion.

Microeconomics vs. Macroeconomics
| Feature | Microeconomics | Macroeconomics |
|---|---|---|
| Unit of Study | Individual economic units (consumers, firms, markets) | Economy as a whole (national income, inflation, unemployment) |
| Focus | Price determination, resource allocation, consumer behavior, firm behavior | Aggregate demand & supply, economic growth, monetary/fiscal policy |
| Tools | Demand and Supply, Market Structures | Aggregate Demand (AD) & Aggregate Supply (AS), National Income concepts |
| Examples | How a rise in sugar price affects its demand; a firm's output decision. | Causes of inflation; policies to combat unemployment; determinants of GDP. |
| Other Names | Price Theory | Income and Employment Theory |
(NCERT Class 11 Microeconomics, Chapter 1; Class 12 Macroeconomics, Chapter 1)
1.1.2. Types of Economies
Economies can be classified based on the ownership of resources and the mechanism used for resource allocation.
Capitalist Economy (Market Economy)
- Ownership: Means of production are privately owned.
- Decision Making: Driven by market forces of demand and supply (price mechanism).
- Motive: Profit maximization.
- Role of Government: Minimal, primarily focused on maintaining law and order, enforcing contracts, and providing public goods.
- Examples: USA (largely), UK (historically strong market orientation).
- Pros: Efficiency, innovation, consumer choice, economic growth.
- Cons: Income inequality, potential for monopolies, market failures, economic instability.
Socialist Economy (Centrally Planned/Command Economy)
- Ownership: Means of production are collectively owned by the state/society.
- Decision Making: Central planning authority decides what, how, and for whom to produce.
- Motive: Social welfare.
- Role of Government: Dominant role in all economic activities.
- Examples: Former USSR, Cuba, North Korea (to a large extent).
- Pros: Greater income equality, provision of basic necessities, stability.
- Cons: Inefficiency, lack of consumer choice, slow innovation, potential for authoritarianism, misallocation of resources.
Mixed Economy
- Ownership: Coexistence of public and private sectors.
- Decision Making: Combination of market forces and government regulation/intervention.
- Motive: Balances profit motive with social welfare.
- Role of Government: Regulates private sector, provides public goods, undertakes welfare activities, and may own key industries.
- Examples: India, Sweden, France.
- Pros: Combines benefits of both capitalism and socialism, allows for government intervention to correct market failures.
- Cons:s Potential for inefficiencies in public sector, excessive regulation, political interference.
India as a Mixed Economy: An Evolution
Post-Independence Adoption (1947)
India adopted a mixed economy model, influenced by socialist ideals and the need for rapid industrialization and equitable development. Significant role for the public sector.
(NCERT Class 11 Indian Economic Development, Chapter 2)
Industrial Policy Resolutions (1948, 1956)
Demarcated roles for public and private sectors, with strategic industries reserved for the public sector. Planning Commission (now NITI Aayog) guided resource allocation.
LPG Reforms (1991)
Liberalization, Privatization, and Globalization marked a significant shift towards a more market-oriented economy, reducing the direct role of the state. Driven by a balance of payments crisis.
(Economic Survey, various years)
Contemporary Status & New Initiatives
India continues to be a mixed economy with increasing reliance on market mechanisms. Government focuses on regulation, facilitation, and welfare. Initiatives like "Make in India," PLI schemes, and NITI Aayog's vision further integrate market principles while ensuring inclusive growth.
(PIB, Budget Speeches, NITI Aayog)
(NCERT Class 11 Indian Economic Development, Chapter 2; IGNOU B.A. Economics Material)
1.1.3. Sectors of Economy
Economic activities are broadly classified into different sectors based on the nature of their operations.
Primary Sector (Agriculture & Allied)
Involves activities that directly use natural resources. Examples: Agriculture, fishing, forestry, mining, quarrying.
- Contribution to Indian GDP: Around 18.3% (FY23, 2nd Advance Estimates, Economic Survey 2022-23).
- Employment: Around 45-46% (PLFS 2021-22).
Secondary Sector (Industry)
Involves the transformation of raw materials into finished goods through manufacturing processes. Examples: Manufacturing, construction, electricity, gas, and water supply.
- Contribution to Indian GDP: Around 28.2% (FY23, 2nd Advance Estimates, Economic Survey 2022-23).
Tertiary Sector (Services)
Provides services rather than tangible goods. Examples: Trade, transport, communication, banking, insurance, real estate, public administration, defense, education, healthcare, tourism, IT services.
- Largest contributor to Indian GDP: Around 53.5% (FY23, 2nd Advance Estimates, Economic Survey 2022-23).
Quaternary & Quinary Sectors
Quaternary (Knowledge): Focuses on knowledge-based activities like R&D, IT, consultancy, education. Example: Software developers, scientists.
Quinary (Decision-making): Involves highest level of decision-making. Examples: CEOs, top government officials, senior research scientists.
(Often discussed in advanced economic texts and IGNOU materials)
(NCERT Class 10 Economics, Chapter 2: Sectors of the Indian Economy)
Formal vs. Informal Sector
| Feature | Formal Sector | Informal Sector (Unorganized Sector) |
|---|---|---|
| Registration | Registered with government, follows rules & regulations | Generally not registered, operates outside formal rules |
| Employment | Regular terms, job security, social security benefits (PF, gratuity, pension) | Casual, irregular, no job security, no social security |
| Taxation | Liable to pay taxes | Often evades taxes |
| Scale | Often larger scale operations | Typically small scale, household-based |
| Examples | Large corporations, public sector enterprises, government employees | Street vendors, domestic workers, small farmers, daily wage laborers |
| Contribution (India) | Lower share in employment, higher in organized output | Over 90% of workforce (NSO, e-Shram data), significant contribution to GDP (estimated 40-50%) |
Recent Developments:
- The e-Shram portal launched by the Ministry of Labour & Employment aims to create a national database of unorganized workers. As of early 2024, over 29 crore workers have registered. (PIB, Ministry of Labour & Employment website)
- Schemes like PM-SVANidhi (for street vendors) aim to provide formal financial access to informal sector workers.
1.1.4. Basic Economic Problems
Every economy, regardless of its type, faces three fundamental economic problems arising from scarcity.
What to produce (and in what quantities)?
This involves deciding which goods and services to produce and how much of each. In a market economy, determined by consumer demand; in a command economy, by central planning; in a mixed economy, a combination of both.
How to produce?
Concerns the choice of production techniques: labor-intensive or capital-intensive. Depends on availability and relative prices of factors of production. Market economies choose efficient methods; command economies may consider employment.
For whom to produce?
Relates to the distribution of produced goods and services among society members. In a market economy, based on purchasing power; socialist aims for equity; mixed economies combine market distribution with government intervention (e.g., PDS, subsidies, taxation).
(NCERT Class 11 Microeconomics, Chapter 1)

Current Affairs and Recent Developments (Last 1 Year)
- National Logistics Policy (2022): Aims to reduce logistics costs, improve efficiency, impacts "how to produce" by improving resource utilization. (PIB, Ministry of Commerce & Industry)
- Digital Public Infrastructure (DPI): India's DPI (Aadhaar, UPI, ONDC) gaining global recognition. ONDC democratizes e-commerce, benefiting small informal businesses and changing "for whom" and "how" goods are sold. (PIB, The Economic Times)
- Focus on "Sunrise Sectors": Government push for sectors like AI, semiconductors, green hydrogen, drones through policies and incentives influences "what to produce" and aims for future economic growth. India Semiconductor Mission (ISM) launched. (Budget Speeches, PIB)
- Debate on Freebies vs. Welfare: Ongoing discussion on economic impact of "revdi culture" versus genuine welfare expenditure, relating to "for whom to produce" and the state's role in a mixed economy. (Newspaper Editorials, Statements by PM, RBI reports)
- Labour Codes Implementation: The four labour codes (on Wages; Industrial Relations; Social Security; and Occupational Safety, Health and Working Conditions) are yet to be fully implemented by all states. Their implementation will significantly impact the formal-informal sector dynamics. (PIB, Ministry of Labour & Employment)
- Rise of Gig Economy and Platform Workers: The Code on Social Security, 2020, includes provisions for gig and platform workers. Rajasthan government's Platform Based Gig Workers (Registration and Welfare) Act, 2023 is a pioneering state-level initiative. This directly addresses the evolving nature of the informal/unorganized sector. (The Hindu, PRS India)
UPSC Previous Year Questions (PYQs)
(a) The cost of the next best alternative foregone.
(b) The total cost of production.
(c) The marginal cost of producing an additional unit.
(d) The average fixed cost.
Answer: (a)
Hint/Explanation: Opportunity cost is the value of what you lose when choosing between two or more options.
(a) 1 only
(b) 2 only
(c) Both 1 and 2
(d) Neither 1 nor 2
Answer: (a)
Hint/Explanation: This question relates to the broader economic environment. Inflation erodes the real value of money. Debtors repay loans with money that is worth less, so they benefit. Bondholders (creditors) receive fixed interest payments that are worth less in real terms. This connects to "for whom to produce" as inflation redistributes wealth.
- Inadequate infrastructure
- Restrictive labor laws
- Complex regulatory environment
- Lack of technological upgradation
Select the correct answer using the code given below:
(a) 1 and 2 only
(b) 2 and 3 only
(c) 1, 3 and 4 only
(d) 1, 2, 3 and 4
Answer: (d)
Hint/Explanation: All these factors have contributed to challenges in the manufacturing sector, influencing decisions on "how to produce" and the overall sectoral contribution.
