Scale of operations — FAQ
Frequently asked questions for 9609 Scale of operations. Direct answers first, then deeper explanation — then practise with marking.
Are economies of scale the same as 'spreading fixed costs'?
Not exactly. 'Spreading fixed costs' (or technical economies) is one important type of economy of scale, but it's not the whole story. The concept of spreading fixed costs over higher output also applies in the short run. Economies of scale is a broader, long-run concept that includes many other factors like bulk-buying discounts, managerial specialisation, and cheaper finance, where all factors of production are considered variable.
Can a small business ever be more efficient than a large one?
Yes. A small business operating at its own minimum efficient scale (MES) can have lower average costs than a very large business that has grown too big and is suffering from significant diseconomies of scale (e.g., bureaucracy, poor communication). The optimal scale varies by industry; for some niche markets or service-based industries, a small scale is the most efficient.
Do all businesses eventually suffer from diseconomies of scale if they keep growing?
While the theoretical model suggests this, it is not inevitable in practice. Many of the largest global companies are highly successful and have not been crippled by diseconomies of scale. They use strategies such as decentralisation, creating smaller autonomous divisions, and investing in advanced communication technologies to overcome the potential problems of large size. This can create a long, flat section on their LRAC curve, allowing them to operate efficiently across a wide range of outputs.
