Study Notes

Network Effects

Products display positive network effects when more usage by one user increases value for other users.
Network effects are similar to network externalities, although they are formally different.
Network effects are commonly found in IT industries, including software, microprocessors, telecommunications, e-commerce, and electronic marketplaces.
Examples include spreadsheets, databases, networking equipment, and DVD players.

Types of Network Effects

Direct: Increased usage directly increases value (e.g., telephone service).
Indirect: Increased usage leads to more valuable complementary goods increasing the original product's value (e.g., Windows and its applications).
Two-sided: Increased usage by one user group increases the value of a complementary product for another user group (e.g., hardware/software platforms).
Local: Product value depends on the actions of a small subset of users within a connected network (e.g., instant messaging).

Economic Consequences of Network Effects

Increasing returns in usage lead to substantial changes in competition.
Early leads are crucial in network markets.
Dominant firms (or products) often emerge, as seen in Microsoft's control of productivity software.

Strength of Network Effects

When strong, platform value increases significantly with user numbers (e.g., Facebook).
Network effect strength varies and may change over time (e.g., Windows).

Risk of Disintermediation

Network members bypassing a central hub can be problematic for the platform.
Platforms employ techniques to deter this (e.g., terms of service restrictions).
Actions that make platforms more cumbersome can risk disintermediation (e.g., offering streamlined alternatives)..

Multihoming

Multihoming is using multiple platforms simultaneously.
When widespread on both sides of a platform, it can be challenging for a platform to remain profitable (e.g., ride-hailing).

Network Clustering

Network fragmentation into local clusters decreases platform stability.
