[Assess students' ability to apply Cournot and Bertrand oligopoly models to derive Nash equilibria and compute equilibrium prices, outputs, and profits. Scope includes linear demand with constant marginal cost (symmetric and simple asymmetric cases), homogeneous vs. differentiated products, and the effects of number of firms and capacity constraints. Require algebraic derivations, a short numerical example, and interpretation of consumer surplus, producer surplus, deadweight loss, and policy implications.]
