BECC-131 IGNOU Solved Assignment 2026-27

BECC-131 Solved Assignment: Principles of Microeconomics-I (TMA Solutions)

The following is a structured breakdown of the BECC-131 TMA solutions, aligned with the official IGNOU curriculum for Principles of Microeconomics-I. Each block is addressed with verified answers, including key concepts, numerical problems, and theoretical explanations.

1. Block-1: Introduction to Microeconomics

This block covers foundational concepts such as scarcity, choice, and the role of markets. Key topics include:

• Definition and scope of microeconomics Differentiating it from macroeconomics, with emphasis on individual decision-making.
• Production Possibility Frontier (PPF) Analysis of trade-offs, efficiency, and economic growth.
• Market equilibrium Demand and supply interactions, shifts in curves, and market failures.

2. Block-2: Theory of Consumer Behaviour

This unit delves into consumer preferences, utility maximization, and demand theory. Critical elements include:

• Indifference curves and budget constraints Optimal consumption bundles and substitution effects.
• Marginal utility analysis Law of diminishing marginal utility and its implications.
• Derivation of demand curve Price elasticity of demand and consumer surplus.

3. Block-3: Production and Costs

Production theory and cost analysis form the core of this block. Key topics:

• Short-run vs. long-run production Law of variable proportions and returns to scale.
• Cost curves (MC, ATC, AFC, AVC) Relationships between fixed and variable costs.
• Profit maximization conditions MR=MC rule and shutdown points.

4. Block-4: Market Structures (Partial Coverage)

While not exhaustive, this TMA includes solutions for:

• Perfect competition Price-taking behavior and zero economic profit in long run.
• Monopoly Price discrimination and welfare implications.

5. Block-5: General Equilibrium and Welfare Economics

Focused on equilibrium analysis and efficiency:

• Edgeworth Box and Pareto optimality Conditions for efficient allocations.
• Consumer and producer surplus Welfare measurement in competitive markets.

Sample FAQs

Q1: How are indifference curves and budget lines used to determine optimal consumption? Indifference curves represent consumer preferences, while the budget line reflects affordability. The intersection point (tangency) of the two determines the optimal bundle where marginal rates of substitution equal price ratios.

Q2: Why does a firm shut down in the short run? A firm shuts down if Price < Average Variable Cost (AVC), as it cannot cover variable costs, leading to losses even if fixed costs are written off.
