Which statement best defines network effects?

• A. The value of a product increases as more users join
• B. A platform reduces switching costs for users
• C. Owners can benefit from scale economies
• D. A product's value remains constant with user count

Answer: (A)

Network effects describe a situation where the product’s value to each user grows as more people use it. When more users join, the platform becomes more useful—there are more connections, more content, more opportunities to transact, or more complementary services. That positive feedback loop is the essence of network effects, and that’s why the statement that the value increases as the user base expands is the best definition. For example, a social network becomes more valuable as more friends and acquaintances are on it, and a marketplace becomes more valuable as more buyers and sellers participate. The other ideas touch on related business concepts but don’t capture this core idea: reducing switching costs helps retention, but not the value growth tied to the growing user base; economies of scale concerns costs, not user-perceived value with more users; and if value stayed constant regardless of users, there would be no network effect at all.
