Assess students' ability to analyze strategic pricing and output decisions in oligopolies using game-theory tools. Scope: identify and compute Nash equilibria in Cournot- and Bertrand-style payoff matrices, derive best-response functions and equilibrium quantities/prices, evaluate incentives and stability of collusion (including repeated-game enforcement), compare collusive vs competitive outcomes for firm profits, consumer surplus, and social welfare (producer surplus, consumer surplus, deadweight loss), and interpret policy implications for antitrust enforcement and market efficiency.
