Definition
Economies of Scale
Economies of scale are cost advantages that arise when producing in larger volumes lowers the average cost per unit, a key source of competitive advantage.
As output rises, fixed costs spread over more units and bulk buying cuts input costs, so average cost falls. This lets large firms underprice rivals and is a barrier to entry that can foster oligopoly or monopoly.
India's manufacturing push and large-scale production incentives (like PLI schemes) aim to help firms achieve economies of scale to compete globally. Beyond a point, diseconomies of scale (bureaucracy, coordination costs) can set in, raising average costs again.
