The saying “the bigger the factory, the lower the cost” refers to the concept of economies of scale.
This is an economic principle where the average cost per unit of output decreases as the scale of production increases.
Essentially, as a company produces more goods, it becomes more efficient, and the cost of producing each individual item goes down.
How It Works?
Economies of scale occur for several reasons:
- Spreading Fixed Costs: A factory has many fixed costs that don’t change regardless of how much is produced, such as rent, machinery, and management salaries. When you produce more goods, these fixed costs are divided among a larger number of units, significantly lowering the average cost per unit. For example, if a factory’s rent is $10,000 per month and it produces 1,000 units, the rent cost per unit is $10. If it increases production to 10,000 units, the rent cost per unit drops to just $1.
- Bulk Buying: Large factories can buy raw materials, components, and other inputs in much larger quantities. Suppliers often offer discounts for bulk orders, which lowers the cost per unit of these materials.
- Specialization and Division of Labor: In a larger factory, workers can specialize in a single task on an assembly line. This specialization makes them highly skilled and efficient at that one job, leading to faster production and fewer errors.
- Technological Advantages: Bigger companies have the capital to invest in advanced, large-scale machinery and technology that are more efficient and can produce more goods at a lower cost per unit. This technology might be too expensive or complex for a smaller factory to justify.
Internal vs. External Economies of Scale
- Internal Economies of Scale: These are cost savings that a company achieves due to its own growth and expansion, as described above (e.g., bulk buying, specialization).
- External Economies of Scale: These are cost advantages that benefit all firms within an industry due to the growth of that industry as a whole. For example, as an industry grows in a particular city, specialized infrastructure, a skilled labor pool, and a network of suppliers might develop, which lowers costs for all companies in that area.
The Limit: Diseconomies of Scale
While “bigger is better” holds true for a while, it doesn’t last forever. If a factory or company grows too large, it may experience diseconomies of scale. This is when the average cost per unit begins to increase due to problems associated with large-scale operations, such as:
- Managerial Inefficiency: Managing a very large and complex organization can be difficult, leading to communication breakdowns and slower decision-making.
- Worker Alienation: In a very large factory, workers can feel disconnected from the company and their work, leading to lower morale and reduced productivity.
