Test students' ability to analyze strategic pricing and bundling by dominant platforms in two-sided markets with network effects; cover first-, second-, and third-degree price discrimination, single and mixed bundling, platform fee structures, multi-homing effects, and demand externalities. Tasks include deriving equilibrium strategies, performing comparative statics, calculating consumer and total welfare implications, identifying exclusionary harms (foreclosure, raising rivals’ costs), and proposing regulatory/policy responses using formal two-sided market models and case scenarios.
