Microeconomics studies how individual consumers, producers and markets make economic decisions under scarcity. Scarcity forces every economy to choose what to produce, how to produce and for whom to produce.
Economics begins with one basic fact: wants are unlimited, but resources are scarce. Important Questions Class 12 Micro Economics Chapter 1 help CBSE 2026 students revise the Introduction chapter through NCERT-based answers and school-exam patterns. The NCERT 2026-27 chapter covers a simple economy, scarcity, central problems, production possibility frontier, opportunity cost, economic systems, positive and normative economics, and the difference between microeconomics and macroeconomics.
Key Takeaways
- Scarcity: Every individual and society has limited resources compared to unlimited wants.
- Central Problems: Every economy decides what to produce, how to produce and for whom to produce.
- PPF: Production possibility frontier shows maximum possible combinations of two goods.
- Microeconomics: It studies individual consumers, producers and markets for specific goods.

Important Questions Class 12 Micro Economics Chapter 1: CBSE 2026 Exam Focus
The first chapter builds the language of Microeconomics. Students need clean definitions because later chapters use consumer, producer, market and price concepts.
CBSE 2026 questions can ask direct definitions, differences, examples and short explanations from NCERT Chapter 1.
1. What is Microeconomics in Class 12?
Microeconomics studies the behaviour of individual economic agents in markets for different goods and services. It explains price and quantity determination.
It studies consumers, producers and individual markets.
For example, it can study the market for rice or mobile phones.
2. What is the main idea of Chapter 1 Introduction in Microeconomics?
The main idea is that scarcity creates choice and economic problems. Every economy has limited resources.
People want many goods and services. Resources cannot satisfy all wants together.
This creates the need for allocation and distribution.
3. Why does scarcity create economic problems?
Scarcity creates economic problems because resources have alternative uses. A resource used for one good cannot be used for another at the same time.
For example, land can grow food crops or support housing.
This forces society to choose between alternatives.
4. What are goods and services in Economics?
Goods are physical objects, while services are intangible activities that satisfy wants. Food, clothes and machines are goods.
Teaching, medical treatment and transport support are services.
NCERT uses goods and services to explain everyday economic needs.
5. What is a simple economy?
A simple economy is a society where people produce some goods or services and exchange them for others. Each decision-making unit owns limited resources.
A farmer may produce corn. A weaver may produce cloth.
Both need other goods and services through exchange.
Class 12 Micro Economics Chapter 1 Questions and Answers for NCERT Exercise
NCERT exercise questions cover the most reliable school-exam prompts. These questions test definitions, differences and core reasoning.
Class 12 Micro Economics Chapter 1 questions and answers should stay close to scarcity, choice and economic systems.
6. Discuss the central problems of an economy.
The central problems of an economy are what to produce, how to produce and for whom to produce. These problems arise due to scarcity.
- What to produce:
The economy must choose goods and quantities.
- How to produce:
The economy must choose labour-intensive or machine-intensive methods.
- For whom to produce:
The economy must decide how output gets distributed.
These problems affect resource allocation and final goods distribution.
7. What do you mean by the production possibilities of an economy?
Production possibilities mean all possible combinations of goods and services an economy can produce. Resources and technology remain given.
For example, an economy may produce different combinations of corn and cotton.
Each combination uses the available resources in a different way.
8. What is a production possibility frontier?
A production possibility frontier is the curve showing maximum possible combinations of two goods. It assumes given resources and technology.
Points on the PPF show full and efficient resource use.
Points below the PPF show underemployment or inefficient use.
9. Discuss the subject matter of Economics.
Economics studies production, consumption, exchange, allocation and distribution under scarcity. It explains how people use limited resources.
It also studies how goods and services reach different people.
Microeconomics and macroeconomics form two broad branches of the subject.
10. Distinguish between a centrally planned economy and a market economy.
A centrally planned economy uses government decisions, while a market economy uses price signals.
| Basis |
Centrally Planned Economy |
Market Economy |
| Decision-maker |
Government or central authority |
Buyers and sellers |
| Resource allocation |
Planned by authority |
Guided by prices |
| Main focus |
Socially desirable allocation |
Free exchange |
In reality, most economies are mixed economies.
11. What do you understand by positive economic analysis?
Positive economic analysis studies how economic mechanisms function. It deals with facts and cause-effect relationships.
Example: “A rise in price reduces demand” is a positive statement.
It can be checked with data or observation.
12. What do you understand by normative economic analysis?
Normative economic analysis studies whether an economic outcome is desirable. It involves value judgement.
Example: “The government should provide free basic healthcare” is normative.
It expresses what ought to happen.
13. Distinguish between microeconomics and macroeconomics.
Microeconomics studies individual markets, while macroeconomics studies the economy as a whole.
| Basis |
Microeconomics |
Macroeconomics |
| Unit of study |
Individual consumer, firm, market |
Whole economy |
| Main variables |
Price and quantity of one good |
Output, employment, price level |
| Example |
Market for wheat |
National income |
NCERT describes microeconomics as individual market analysis and macroeconomics as aggregate analysis.
Central Problems of an Economy Class 12 Important Questions
An economy cannot produce everything in unlimited quantities. The central problems arise because resources remain scarce.
Central problems of an economy Class 12 answers should connect scarcity, choice and allocation.
14. Why does every economy face central problems?
Every economy faces central problems because resources are scarce and wants are unlimited. Resources also have competing uses.
A machine can produce consumer goods or capital goods.
Society must choose one allocation over another.
15. What is meant by “what to produce”?
“What to produce” means deciding which goods and services an economy should produce. It also includes quantity decisions.
An economy may choose more food or more luxury goods.
It may choose more education services or more military services.
16. What is meant by “how to produce”?
“How to produce” means choosing the technique of production. The economy must select labour or machines.
Labour-intensive methods use more workers.
Capital-intensive methods use more machinery.
17. What is meant by “for whom to produce”?
“For whom to produce” means deciding how goods and services get distributed. It asks who gets more and who gets less.
An economy may ensure minimum consumption for everyone.
It may also provide basic education and health services.
18. Why is allocation of resources important?
Allocation of resources is important because resources can produce different goods. Wrong allocation can create shortages or wastage.
If people want more corn, resources may shift from other goods to corn.
This keeps production closer to social needs.
19. What is distribution in Economics?
Distribution means sharing final goods and services among people in an economy. It decides who consumes what amount.
Distribution can depend on income, ownership and policy.
It forms one central concern of Economics.
20. How are central problems solved in a market economy?
Market economies solve central problems through price signals. Higher demand raises price.
Producers see higher price as a signal.
They produce more of the demanded good.
21. How are central problems solved in a planned economy?
A planned economy solves central problems through government decisions. The central authority decides production and distribution.
It may produce more health or education services.
It may also intervene for equitable distribution.
Production Possibility Frontier Class 12 Questions with Answers
A PPF helps students see scarcity in a diagram. It shows that producing more of one good has a cost.
Production possibility frontier Class 12 questions often ask meaning, assumptions, shifts and opportunity cost.
22. What does a production possibility frontier show?
A production possibility frontier shows maximum possible combinations of two goods. It assumes fixed resources and technology.
For example, an economy can produce corn or cotton.
Each point on the frontier uses resources fully.
23. What is a production possibility set?
A production possibility set is the collection of all possible output combinations. It includes combinations possible with given resources and technology.
The PPF forms the boundary of this set.
Points inside the set are attainable.
24. What does a point below the PPF show?
A point below the PPF shows underemployment or inefficient resource use. The economy produces less than its capacity.
Some resources may remain unused.
Some resources may also face wasteful use.
25. What does a point on the PPF show?
A point on the PPF shows full and efficient use of resources. The economy produces the maximum possible output combination.
More of one good needs less of another good.
This shows scarcity and trade-off.
26. What does a point outside the PPF show?
A point outside the PPF shows an unattainable production combination. Current resources and technology cannot produce it.
The economy needs more resources or better technology.
Growth can shift the PPF outward.
27. Why is the PPF generally downward sloping?
The PPF slopes downward because resources are scarce and have alternative uses. More of one good needs resources from another good.
Producing more corn means producing less cotton.
This shows opportunity cost.
28. Why is the PPF usually concave to the origin?
The PPF is usually concave because opportunity cost tends to rise. Resources are not equally efficient in all uses.
As more resources shift to one good, larger amounts of the other good get sacrificed.
This creates increasing marginal opportunity cost.
29. What is the difference between movement along PPF and shift of PPF?
Movement along PPF shows reallocation, while shift of PPF shows change in capacity. Movement means more of one good and less of another.
Outward shift shows economic growth.
Inward shift shows loss of resources or technology.
Opportunity Cost Class 12 Micro Economics Questions
Opportunity cost explains the real cost of choice. It measures what a person or society gives up.
Opportunity cost Class 12 Micro Economics questions often connect directly with PPF.
30. What is opportunity cost?
Opportunity cost is the value of the next best alternative sacrificed. It arises because resources have alternative uses.
If land produces wheat instead of cotton, cotton is the opportunity cost.
NCERT calls it the cost of having more of one good.
31. Why is opportunity cost called economic cost?
Opportunity cost is called economic cost because it measures sacrifice in real choice. It includes the alternative forgone.
Money cost may not show the full sacrifice.
Economics studies choices under scarcity.
32. How is opportunity cost shown on a PPF?
Opportunity cost appears as the amount of one good sacrificed for another good. Movement along PPF shows this trade-off.
If corn output rises, cotton output falls.
The lost cotton is the opportunity cost of extra corn.
33. Give one example of opportunity cost in student life.
The opportunity cost of studying Economics for one hour may be one hour of another subject. Time is scarce.
Choosing one activity means giving up another.
This makes opportunity cost useful beyond production.
34. Why does opportunity cost rise on a concave PPF?
Opportunity cost rises because resources are specialised. Some resources suit cotton better than corn.
When these resources shift to corn, cotton loss becomes larger.
This creates increasing marginal opportunity cost.
Market Economy and Centrally Planned Economy Class 12 Questions
Economic systems differ in how they coordinate decisions. NCERT explains market coordination through prices and planning through government decisions.
Market economy and centrally planned economy Class 12 questions usually ask comparison and examples.
35. What is a centrally planned economy?
A centrally planned economy is an economy where the government controls major economic decisions. It decides production, exchange and consumption.
The central authority tries to achieve desired resource allocation.
It may prioritise education, health or equity.
36. What is a market economy?
A market economy is an economy where economic activities happen through markets. Buyers and sellers interact freely.
Prices coordinate their decisions.
Markets may exist physically or through phone and internet.
37. What is a market in Economics?
A market is a set of arrangements where buyers and sellers exchange goods or services. It need not be a physical place.
A market can work through a village chowk, shop, phone or internet.
Free exchange defines a market.
38. How do prices coordinate a market economy?
Prices coordinate a market economy by sending signals to buyers and sellers. Higher demand usually raises price.
Producers read higher price as a signal to increase output.
This helps solve what and how much to produce.
39. What is a mixed economy?
A mixed economy uses both government planning and market mechanisms. Some decisions come from the government.
Other activities happen through markets.
NCERT states that real economies are usually mixed economies.
40. Why is India called a mixed economy?
India is called a mixed economy because both government and markets play important roles. Since Independence, the government has planned many activities.
In recent decades, market activity has increased.
Both systems influence production and distribution.
Positive and Normative Economics Class 12 Questions
Positive analysis explains facts. Normative analysis evaluates outcomes and suggests what should happen.
Positive and normative economics Class 12 questions often ask students to classify statements.
41. What is positive economics?
Positive economics studies how an economic mechanism works. It deals with factual statements.
Example: “Higher prices reduce quantity demanded” is positive.
It can be tested with data.
42. What is normative economics?
Normative economics studies whether an economic outcome is desirable. It includes value judgement.
Example: “The government should reduce income inequality” is normative.
It cannot be tested like a pure fact.
43. Give two examples of positive statements.
Positive statements describe facts or cause-effect relations.
- A rise in petrol price can reduce petrol demand.
- Higher income can increase demand for normal goods.
Both statements can be checked with evidence.
44. Give two examples of normative statements.
Normative statements express opinions about what should happen.
- The government should provide free basic education.
- Rich people should pay higher taxes.
Both statements involve value judgement.
45. Why is the distinction between positive and normative economics useful?
The distinction helps separate factual analysis from value judgement. Positive analysis explains how things work.
Normative analysis judges whether outcomes are desirable.
NCERT notes that both issues remain closely related.
