The Scope of Economics: What Does Economics Actually Study?
Think about your day so far. You woke up, had breakfast, came to school. Every single thing you used — the bed you slept on, the food you ate, the bus or bicycle you took — was produced by someone, somewhere, using limited resources. And you made choices: Which dish to eat? Which route to take? That's the seed of economics.
Economics is not just about money, stock markets, or government budgets. It is the study of choice under scarcity. Scarcity means our wants are unlimited, but the resources to satisfy them — time, land, labour, capital — are limited. So every society must answer three fundamental questions:
- What to produce? (Should we make more phones or more food?)
- How to produce? (Should we use more machines or more workers?)
- For whom to produce? (Who gets to consume what?)
The scope of economics is the answer to: What all does this subject cover? It is the boundary of the field — the topics, methods, and questions that economics deals with.
The Two Broad Branches of Economics
Economics is divided into two main parts, and understanding this division is the first step in grasping its scope.
Microeconomics vs Macroeconomics
Microeconomics (from the Greek mikros = small) studies individual economic units — a single consumer, a single firm, a single market. It asks: How does a household decide what to buy? How does a firm decide how much to produce? How is the price of a particular good determined?
Macroeconomics (from makros = large) studies the economy as a whole. It looks at aggregates — total output, total employment, the general price level, national income. It asks: Why does the whole economy sometimes slow down? What causes inflation? How does the government manage the overall level of economic activity?
The NCERT Class 11 textbook (Introductory Microeconomics) and Class 12 textbook (Introductory Macroeconomics) are built exactly on this division.
What Falls Within the Scope? (The Core Topics)
Here is what the NCERT syllabus actually covers under the scope of economics:
| Microeconomics (Class 11) | Macroeconomics (Class 12) |
|---|---|
| Consumer behaviour (utility, demand) | National income accounting |
| Producer behaviour (cost, supply) | Money and banking |
| Market forms (perfect competition, monopoly) | Determination of income and employment |
| Price determination under different markets | Government budget and the economy |
| Simple applications (price controls, taxes) | Balance of payments and foreign exchange |
The scope also includes normative and positive economics. Positive economics deals with "what is" — facts and cause-effect relationships (e.g., "A rise in price reduces demand"). Normative economics deals with "what ought to be" — value judgments and policy recommendations (e.g., "The government should provide free education"). Both are part of the scope, but positive economics forms the core of your syllabus.
Why Does the Scope Matter?
Knowing the scope tells you what tools you will learn and what questions you can answer.

›Reveal solutionSolution
Economic agents are the decision-makers of an economy — consumers, producers, firms and the government.
In economics, an economic agent (or economic unit) is any individual or institution that takes economic decisions and carries out economic activities. Examples include consumers deciding what to buy, producers and firms deciding what and how much to produce, and the government deciding on taxes and spending. The whole study of economics is about the decisions these agents make and how those decisions interact in markets. This is a basic defini …

Robbins defined economics as a science of scarcity (and choice), so the answer is (d).
Lionel Robbins defined economics as 'the science which studies human behaviour as a relationship between ends and scarce means which have alternative uses'.

Inventory is a stock concept and the change in inventory is a flow concept, so the answer is (a).
Inventory (the stock of unsold goods or raw materials a firm holds) is measured at a particular point of time, so it is a stock. The change in inventory over a period of time (for example, during a year) is measured over an interval and therefore is a flow. Thus inv …

›Reveal solutionSolution
The problem of choice arises from scarcity of resources — option (b).
Since resources are scarce (limited) and have alternative (competing) uses while human wants are unlimited, an economy cannot satisfy all wants at once and must choose how to allocate its resources. Thus scarcity of re …

›Reveal solutionSolution
Microeconomics studies individual units — families, firms, and industries alike.
Microeconomics focuses on the economic decisions and behaviour of individual, specific units within the economy: an individual family/household (how it allocates its budget among goods, theory of consumer behaviour), an individual firm (how it decides output and price, theory of the firm), and an individual industry (how price and quantity are determined in a specific market, e.g., the sugar industry or the steel industry). All three are 'micro' in the sense of being individual, specific unit …
- CBSE 2026Set ANNUAL1 markMCQQ.Macroeconomics studies : (A) the behaviour of individual prices (B) the behaviour of individual quantity of a particular commodity (C) the behaviour of individual income (D) the behaviour of large aggregates such as the general price level of the economy
›Reveal solutionSolution
Macroeconomics studies economy-wide aggregates, not individual prices/quantities/incomes.
Economics is traditionally divided into microeconomics and macroeconomics. Microeconomics studies the behaviour of individual economic units -- a single consumer's choices, a single firm's output decision, the price and quantity of one particular commodity, or one person's income. Macroeconomics, by contrast, studies the economy in aggregate: total output (national income), the general (average) price level of all goods and services, aggregate employment and unemployment, the total money supply, and the overall balance of payments. Options (A), (B) and (C) all describe the behaviour of a single/individual …
