Scale economies
What are Scale economies?
A business in which per-unit cost declines as volume increases. The benefit is lower cost; the barrier is that a challenger must accept a prohibitive loss to reach comparable scale, and the incumbent can retaliate on price. Named by every author in the canon.
How Scale economies work
Requires high fixed or sunk costs relative to variable (software development, content, infrastructure, advertising), or purchasing leverage. Helmer notes it must be scale relative to competitors, not absolute size.

The question to ask of a company
What is the fixed-cost base, and how far below the leader's unit cost would a #2 sit at half the volume? Does the leader's cost advantage let it price challengers out?
