Advanced Microeconomics (Course Code: ECO5CJ301) is the premier Major Core paper taught in Semester 5 of the BA Economics Honours programme under the University of Calicut Four-Year Undergraduate Programme (CUFYUGP 2026 / FYUGP).
This course elevates microeconomic analysis from basic consumer theory to strategic interdependence, non-cooperative game theory, general equilibrium systems, and Pareto welfare economics.

Essential Theoretical Frameworks
1. Non-Collusive Oligopoly Models
- Cournot Model: Duopolists choose quantities simultaneously assuming the rival's output remains constant. Reaction curves intersect at the Cournot equilibrium output ($Q_1 = Q_2 = \frac{A - c}{3B}$).
- Bertrand Model: Duopolists compete on prices rather than output, driving price down to marginal cost ($P = MC$), replicating competitive equilibrium despite only two firms (Bertrand Paradox).
- Stackelberg Leader-Follower Model: First-mover advantage where the leader anticipates the follower's reaction function, capturing a higher market share and profit.
- Paul Sweezy's Kinked Demand Curve: Explains price rigidity in oligopolistic markets through asymmetric demand elasticity (elastic for price increases, inelastic for price cuts).
2. Game Theory & Strategic Interaction
- Normal Form Game Representation: Players, strategies, and payoff matrix.
- Dominant Strategy Equilibrium: A strategy that yields the highest payoff regardless of what rivals do.
- Nash Equilibrium: A strategy profile where no player has a unilateral incentive to deviate.
- Prisoner's Dilemma: Illustrates how rational individual behavior leads to a Pareto sub-optimal outcome, explaining cartel instability in OPEC.
3. General Equilibrium & The Edgeworth Box
- Partial vs. General Equilibrium: Partial equilibrium (Marshall) examines a single isolated market with ceteris paribus; general equilibrium (Walras) models all interconnected markets simultaneously.
- Edgeworth Box in Pure Exchange: Dimensions represent total endowments of Goods X and Y. The contract curve traces the locus of Pareto-efficient allocations where marginal rates of substitution are equal:
$\text{MRS}_{xy}^A = \text{MRS}_{xy}^B$
- Production Equilibrium: Efficiency in factor allocation along the production contract curve where marginal rates of technical substitution are equalized:
$\text{MRTS}_{lk}^X = \text{MRTS}_{lk}^Y$
4. Welfare Economics & Market Failure
- Pareto Criterion: An allocation is Pareto optimal if no individual can be made better off without making someone else worse off.
- First Fundamental Theorem of Welfare Economics: Any competitive market equilibrium is Pareto optimal, provided there are complete markets, perfect information, and no externalities.
- Second Fundamental Theorem: Any Pareto optimal allocation can be sustained as a competitive equilibrium through lump-sum transfers.
- Sources of Market Failure: Externalities (Pigouvian tax solutions), public goods (non-rivalry and non-excludability leading to free-riding), asymmetric information (adverse selection and moral hazard).
Proven Exam Tips for ECO5CJ301
- Master Mathematical Derivations: Practice deriving Cournot reaction functions from linear demand equations ($P = A - B(Q_1 + Q_2)$) and solving for equilibrium output and prices.
- Label the Edgeworth Box Carefully: Draw both origins ($O_A$ and $O_B$), label indifference curves with increasing utility directions, and mark the contract curve clearly.
- Contrast Collusive vs. Non-Collusive Oligopoly: Use a comparative table highlighting assumptions, decision variables, equilibrium price, output, and social efficiency.
