Network Effects: The Moat Competitors Can't Match
Network effects are among the most powerful sources of an economic moat, enabling companies to sustain excess returns by increasing value as more users join. Unlike supply-side economies of scale, network effects are demand-driven, making them difficult for competitors to replicate. Firms like Amazon, Uber, and Airbnb exemplify businesses where network effects play a critical role in long-term defensibility. These effects create a self-reinforcing cycle that strengthens the market position of dominant platforms.
