võrgufektid

Võrgufektid, also known as network effects, is a phenomenon where the value or utility of a good or service increases as more people use it. This concept is particularly relevant in the context of platforms, social networks, and online marketplaces.

There are typically two main types of network effects: direct and indirect. Direct network effects occur when the value of a service for a user increases with the number of other users of the same service. A prime example is a telephone network: the more people who have telephones, the more useful the telephone becomes for everyone. Similarly, social media platforms benefit greatly from direct network effects; the more users a platform has, the more content and connections are available for each user.

Indirect network effects, also known as cross-side network effects, arise when the value of a service for one group of users increases with the number of users in a different, complementary group. This is commonly seen in two-sided markets, such as app stores or ride-sharing platforms. For instance, in an app store, the more users there are, the more attractive it is for developers to create apps, and the more apps there are, the more valuable the app store becomes for users. Conversely, in ride-sharing, more drivers mean shorter wait times for riders, and more riders mean more potential customers for drivers.

Network effects can create powerful positive feedback loops, leading to the dominance of certain platforms or services. Once a critical mass of users is reached, it can become very difficult for competitors to challenge the established player, as new entrants lack the existing network's value. This can lead to "winner-take-all" or "winner-take-most" market structures. Understanding network effects is crucial for businesses operating in digital and platform-based economies.
