Limits of network effects

Social networks, marketplaces, and payment systems become more useful as more people use them. Economists call this a network effect.

Network effects help explain why a few platforms dominate many digital markets.

Direct network effects

A messaging app is more valuable the more of your contacts use it. Each new user directly benefits existing users.

Indirect network effects

In two-sided markets such as app stores or ride-hailing, more users attract more providers, which attracts more users.

Tipping points

Once a platform gains a lead, network effects can make it very hard for rivals to catch up, leading to winner-takes-most outcomes.

Competition concerns

Regulators examine whether dominant platforms use their position to disadvantage competitors, for example through self-preferencing or restrictive terms.

Limits of network effects

Network effects are not unbeatable. Users who use several platforms at once (multi-homing), changing technology, and declining quality can all weaken them.
