What is the Difference Between Economies of Scale and Returns to Scale?
🆚 Go to Comparative Table 🆚Economies of scale and returns to scale are concepts related to the efficiency of production processes. However, they differ in their focus and implications:
- Economies of scale refers to the feature of many production processes in which the per-unit cost of producing a product falls as the scale of production rises. In other words, it becomes cheaper to produce the average unit as the scale of production increases. This can be characterized by a decreasing average cost curve.
- Returns to scale refers to the feature of many production processes in which productivity per unit of labor rises as the scale of production rises. In other words, output per unit of labor input increases as the scale of production rises. If a firm enjoys increasing returns to scale, it means that a k-fold increase in output can be achieved by increasing all inputs k-fold.
In summary, economies of scale focus on the reduction of per-unit costs, while returns to scale focus on the increase in productivity per unit of labor input as the scale of production increases.
Comparative Table: Economies of Scale vs Returns to Scale
Economies of scale and returns to scale are related concepts in economics, but they have distinct meanings and implications. Here is a table summarizing the differences between the two:
| Economies of Scale | Returns to Scale |
|---|---|
| Refers to the reduction in the per-unit cost of production as the scale of production increases | Describes the production ratios of inputs and outputs, and how the percentage change in outputs compares to the percentage change in inputs |
| Occurs when the cost per unit of output decreases as output increases | Can be increasing, constant, or decreasing, depending on the relationship between input and output changes |
| Typically observed in large-scale, capital-intensive industries | Holds constant for price-taking firms in competitive markets |
| Higher output can be achieved at a lower cost | The percentage change in output is higher than the percentage change in inputs, leading to increasing returns to scale |
| Can involve economies or savings in production | Increasing returns to scale indicate that a proportional increase in inputs results in a larger increase in outputs |
In summary, economies of scale focus on the reduction of per-unit costs as production increases, while returns to scale describe the relationship between input and output changes. Economies of scale are a specific type of returns to scale, where the increase in output leads to lower costs per unit of production.
