Background
Diseconomies of scale occur when increasing production leads to a higher average cost per unit. This phenomenon is contrasted with economies of scale, where costs per unit decrease as production increases.
Historical Context
The term “diseconomies of scale” has roots in classical economic theory. The evolution of large industrial firms in the late 19th and early 20th centuries spotlighted the negative aspects of scale, prompting economists to examine and articulate the conditions under which expansion could become counterproductive.
Definitions and Concepts
Diseconomies of scale arise when a firm produces beyond the minimum point of the long-run average cost (LRAC) curve. This results in the average cost of each successive unit of output increasing.
Key Concepts:
- Long-Run Average Cost (LRAC) Curve: A graphical representation showing the lowest possible cost at which any output level can be produced when all inputs are variable.
- Minimum Efficient Scale (MES): The level of output at which a firm can produce at the lowest average cost.
Major Analytical Frameworks
Classical Economics
Classical economists didn’t delve deeply into the concept of scale diseconomies, primarily focusing on production and cost in simpler economies.
Neoclassical Economics
Keynesian Economics
Marxian Economics
Institutional Economics
Behavioral Economics
Post-Keynesian Economics
Austrian Economics
Development Economics
Monetarism
Comparative Analysis
Various economic schools offer distinct views on scale economies and diseconomies. Neoclassical economics provides the foundational concept using simplifications and modeled assumptions. Contemporary analyses extend these ideas in more complex and realistic scenarios.

Related Terms with Definitions
- Economies of Scale: Reduction in average cost per unit as scale of operation increases.
- Marginal Cost: The additional cost of producing one more unit of output.
- Fixed Cost: Costs that do not change with the level of output produced.
- Variable Cost: Costs that vary directly with the level of output.
By understanding diseconomies of scale, firms can recognize when expansion may become detrimental to cost efficiency and overall profitability.
