Knowra Network effect Network effect A network effect occurs when a product or service becomes more valuable to each user as its user base grows. Its strength depends on how users’ participation changes value for other users.
Metcalfe's law : A heuristic that estimates a network’s value as proportional to the square of its number of users. It captures the intuition behind direct effects, though real networks rarely gain value at that exact rate.
Two-sided market : A market in which a platform connects two distinct groups whose participation affects each other. Platforms often grow by coordinating interdependent groups such as buyers and sellers.
Economies of scale : A reduction in average production cost as the quantity of output increases. Cost advantages come from production volume, not necessarily from users making the product more valuable.
Winner-takes-all market : A market in which one firm captures most demand, leaving little business for competitors. Feedback between user growth and value can make one network pull far ahead.
Digital platform regulation : Government rules addressing the conduct, access, and market power of digital platforms. Regulators debate whether interoperability and access rules can preserve competition between networks.
Direct network effect : A network effect in which additional users directly increase value for other users of the same service. Telephone and messaging networks gain usefulness when more people can be reached.
Platform economy : Economic activity organized around digital platforms that connect users, businesses, or service providers. Network effects help explain why platform businesses can expand rapidly and dominate markets.
Switching cost : A cost, effort, or loss a customer faces when moving from one product or service to another. A strong network can raise the value users would give up by switching.
Path dependence : A process in which earlier choices constrain later outcomes, even when alternatives become available. An early lead can persist because users, developers, and businesses coordinate around one network.
Interoperability : The ability of different systems or products to exchange information and work together. Interoperability can let users connect across rival networks, reducing the advantage of size.
