Network Effects• Definition: where value of a product to one
consumer depends on number of other consumers using it
• Examples– Actual networks: e.g. telephone, fax machines,
instant messaging, etc.– Standards: e.g. QWERTY keyboard, MP3, etc.– Compatible products: e.g. VCRs, DVD, computer
operating systems, etc.

Costs and Benefits
• Benefits– Competing standards can be inefficient– Lower training costs, portability– Wider selection in complementary markets
• Costs– Lock in to suboptimal standard– Issues of market power where standard owned
