Internal economies of scale happen when a firm's average costs decrease as the industry as a whole expands.
Increased profits - Economies of scale produce larger profits, which in turn boost returns on capital and give enterprises a platform to expand. Greater business scale - As a company expands, it becomes more stable and less prone to external challenges, such as hostile takeover offers.
When an item or service can be produced in greater quantities with (on average) lower input costs, economies of scale arise. It is also possible to achieve external economies of scale, when a single industry gains from a change like better infrastructure.
