Decreasing costs, a fundamental concept in economics, refer to a situation where the per-unit cost of production decreases as the volume of production increases. This phenomenon is often associated with economies of scale and results in more efficient resource usage and cost savings for businesses as they scale their operations.
Types of Decreasing Costs
Internal Economies of Scale
Internal economies of scale arise from within the firm itself. These can be due to several factors such as:
- Technical Economies: Improved production techniques and machinery can lead to higher efficiency.
- Managerial Economies: Better management practices and specialized managerial functions can enhance productivity.
- Financial Economies: Larger firms often have better access to capital at lower costs.
- Marketing Economies: Bulk buying and selling lower the average cost of supplies and marketing respectively.
External Economies of Scale
External economies of scale occur outside the firm but within an industry. These include:
- Industry Growth: As an industry expands, suppliers of components or raw materials also scale up, reducing costs.
- Technological Advancements: Innovations and shared research within an industry can benefit all participating firms.
Causes of Decreasing Costs
- Production Techniques: Advanced technology and automation reduce the need for manual labor, lowering production costs.
- Bulk Purchasing: Buying raw materials in larger quantities often reduces cost per unit.
- Specialization and Division of Labor: Specialization increases efficiency and productivity, reducing costs.
- Learning Curve Effect: As firms produce more, they become more efficient over time due to improved skills and processes.
Practical Examples
Automobile Industry
In automobile manufacturing, economies of scale are achieved by producing a large number of vehicles using automated assembly lines. This reduces the average cost per vehicle.
Tech Industry
Tech companies, such as those producing microchips, benefit from decreasing costs as their production scales up, leading to lower costs per chip and enhanced market competitiveness.
Historical Context
The concept of decreasing costs and economies of scale has long been recognized, with its roots tracing back to the works of Adam Smith in “The Wealth of Nations” (1776). Smith introduced the idea of the division of labor improving productivity and reducing costs, a precursor to modern concepts of economies of scale.
Comparisons and Related Terms
Economies of Scale vs. Diseconomies of Scale
- Economies of Scale: Cost advantages gained by increasing the scale of production, lowering the per-unit cost.
- Diseconomies of Scale: When a firm or industry becomes too large and inefficiencies start to increase per-unit costs.
Fixed Costs vs. Variable Costs
- Fixed Costs: Costs that do not change with the level of output, such as rent and salaried employees.
- Variable Costs: Costs that vary directly with the level of output, such as raw materials and hourly wages.
FAQs

Summary
Decreasing costs are central to understanding how firms can grow efficiently and profitably by leveraging internal and external economies of scale. By optimizing production techniques, management practices, and purchasing strategies, businesses can reduce per-unit costs and gain a significant competitive edge. Understanding this concept is essential for anyone involved in economics, business strategy, and financial planning.
