Network effects
Network effects occur when the value of an offering to a user depends on participation by other users or complementary groups. Direct effects can arise within one user group, while indirect effects can connect different sides of a platform. More participation is not always beneficial: congestion or low-quality interactions can reduce value. Network effects are different from lower unit costs caused by scale.
Worked example
A marketplace can become more useful to buyers when more suitable sellers participate, while sellers value access to relevant buyers. Poor matching or congestion can weaken that benefit even as registrations rise.
Common mistake
Do not equate network effects with a company having a large computer network or assume user numbers alone guarantee profitability or permanent advantage.
