Diseconomies of Scale
What are Diseconomies of Scale?
Diseconomies of scale lead the marginal cost of a product to increase as a company grows. This is the opposite of economies of scale which cause the marginal cost for a product to decrease as a result of efficiencies achieved as a company grows and can spread its fixed costs over a larger quantity of products/services offered.
How Do Diseconomies of Scale Work?
As a firm grows, it seeks to reduce the marginal cost of its products, increasing efficiency as it increases production. Improved efficiency results in greater profit per unit of production. However, when there are diseconomies of scale, after a certain point, which varies by industry and by business, the marginal cost for the product begins to rise. Factors contributing to inefficiency may include cumbersome bureaucracy, high costs of geographical expansion, high legacy costs (such as pension liabilities from an aging workforce), and overlapping product lines that compete for the same market and production resources. The standard curve showing the relationship between product cost and quantity and the downward curve toward economies of scale and the upward curve into diseconomies of scale demonstrates this process.
Why Do Diseconomies of Scale Matter?
When a company/product reaches the point where its marginal cost increases, it becomes a target for smaller, more efficient firms to compete for its business. A company at this point may evaluate restructuring its operations, spinning off various production units, or closing some of its operations. Companies also use a variety of strategies to minimize diseconomies of scale, such as flattening management structure, investing in technology to improve communication, careful market segmentation, and decentralizing production.
