Assess students' ability to analyze how first-, second-, and third-degree price discrimination affect consumer surplus, firm profit, and total welfare in a single-product monopoly context. Tasks should include: using demand and marginal-cost diagrams to illustrate allocations and transfers under each discrimination type; computing changes in consumer surplus, producer surplus (profit), and deadweight loss from supplied numeric examples; and explaining key assumptions (no arbitrage, market segmentation, information requirements) and policy implications in short-answer form.
