Scale economies shared
The rule
A business that hands its size savings back to customers as lower prices builds a wall rivals cannot cross. The cost is thinner margins today.
Where it flips
A company with no size advantage cutting prices is not sharing savings, it is just losing a price war. Where it misleads: you praise every price cut. The fix: check that real size savings sit behind the lower prices.
Instead of keeping the savings from its size as fatter margins, the company passes them to customers as lower prices. Lower prices bring more buyers. More buyers bring more size. More size cuts the cost again. It is a loop rivals cannot match without also giving the savings away. The margins look ordinary; the protective wall is huge.
A worked example
A retailer keeps its gross margin flat for a whole decade while its revenue grows six times over. That flat margin is the strategy at work, not a sign of standing still. [illustrative]
