[Assess students' ability to analyze how own-price and cross-price elasticities shape optimal pricing and bundling strategies in differentiated-product oligopolies. Scope includes calculating and interpreting elasticity coefficients, modeling strategic responses (e.g., Bertrand/Hotelling contexts), evaluating demand interdependence and profit trade-offs, and composing short quantitative and analytical justifications for single-product pricing, mixed bundles, and pure bundles.]
