Positive economic analysis is concerned with explaining how economic mechanisms function and identifying the objective outcomes likely to result from them. It is based on facts and observable relationships rather than value judgments.

Positive economic analysis examines how different economic mechanisms function and predicts the allocation of resources and the resulting mix of goods and services under each mechanism.

Normative economic analysis is concerned with evaluating economic mechanisms and judging whether their outcomes are desirable or undesirable. Hence, both the Assertion and Reason are correct, and the Reason explains the Assertion.

Normative analysis first identifies the available mechanisms, then studies the resource allocations and outcomes produced by each mechanism, and finally evaluates which mechanism is most desirable for society.

Positive Economic Analysis → Explains how mechanisms function. Normative Economic Analysis → Evaluates whether mechanisms are desirable. Microeconomics → Studies price and quantity determination in individual markets. Macroeconomics → Studies aggregate economic performance.

Normative economics judges whether an economic mechanism or its outcomes are desirable. However, to evaluate an outcome, one must first understand how the mechanism works, which is the role of positive economics. Hence, normative economics cannot be properly understood in isolation from positive economics.

Microeconomics studies the behaviour of individual consumers and producers and explains how prices and quantities of goods and services are determined through market interaction. The aggregate price level is a macroeconomic concept.

In microeconomics, individual consumers and producers participate in the market. Through their interaction, demand and supply determine the price and quantity of the commodity.

Economy as a whole → Aggregate price level. Individual market → Price of a single commodity. Macroeconomics → Total output and employment. Microeconomics → Individual consumers and producers.

Macroeconomics examines aggregate measures such as total output, employment, and the general price level to understand the overall performance of the economy, rather than individual markets.

Unlike microeconomics, which studies individual markets, macroeconomics focuses on the overall performance of the economy through aggregate measures such as total output, employment, and the aggregate price level.

The Assertion is true because macroeconomics examines how total output is determined and grows over time. The Reason is false because the behaviour of individual economic agents is the subject matter of microeconomics, not macroeconomics.

Aggregate price level → Why do prices rise? Total output → How is it determined and how does it grow? Employment → Are the economy's resources fully employed? Economic growth → How does total output increase over time?

Macroeconomics examines whether the economy's resources are fully employed and investigates the causes of unemployment. The production decisions of a single family farm belong to microeconomics.

A major objective of macroeconomics is not only to measure employment but also to identify the reasons behind the unemployment of resources so that policies can improve overall economic performance.

The introductory text focuses on: Individual consumers → Microeconomics Individual producers → Microeconomics Total output → Macroeconomics Aggregate price level → Macroeconomics

According to the plan of the textbook, the topics are introduced in the following sequence: 1. Basic ideas in Microeconomics 2. Consumer's Behaviour 3. Basic Ideas of Production and Cost This order builds a foundation before moving to production and market analysis.

The textbook first explains production, cost, and producer behaviour, which form the basis of the supply side of the market. Only after understanding supply does it analyze price and quantity determination in a perfectly competitive market. Therefore, both the Assertion and Reason are true, and the Reason correctly explains the Assertion.

The later chapters of the textbook cover: Price determination in a perfectly competitive market. Quantity determination in a perfectly competitive market. Other forms of market structures beyond perfect competition. Hence, all three statements are correct.

The passage states that the distinction depends on the purpose of analysis: Positive economics studies how economic mechanisms function. Normative economics evaluates whether those mechanisms and their outcomes are desirable. Therefore, Option B is correct.

The passage clearly concludes that the distinction between positive and normative economic analysis is not a very sharp one, because understanding one often requires knowledge of the other.
