High multi-homing and low switching costs create what effect for platform competition?

• A. Intensifies competition, requiring differentiation or stronger loyalty mechanisms
• B. Decreases competition
• C. Eliminates the need for governance
• D. Automatically increases profits

Answer: (A)

When users can use multiple platforms (high multi-homing) and moving between them is easy (low switching costs), platforms must compete more fiercely for each user and for each side of the market. No single platform can rely on being the default or on lock-in to harvest profits. Instead, they need to differentiate—offering unique features, better experiences, and broader ecosystems—and implement loyalty mechanisms to keep users from drifting to rivals. In this setup, competition intensifies because users can switch with little friction, so platforms must continuously improve and incentivize continued use. The other options miss this dynamic: competition isn’t decreased, governance remains relevant, and profits aren’t automatically increased when switching costs are low.
