Definition
Decreasing Costs, also known as economies of scale, refer to the scenario in which the unit cost of production or output reduces as the volume of production increases. This phenomenon often results from increased operational efficiency, bulk purchasing of raw materials, and better utilization of fixed costs, which leads to a decrease in the average cost per unit.
Examples
-
Manufacturing Industry: A car manufacturer invests in automated assembly lines. As production increases, the cost per car decreases due to the efficiency brought by automation and the high volume of production.
-
Retail Industry: A large retail chain purchases goods in bulk. The bulk purchase leads to discounts from suppliers, reducing the cost per unit of goods sold in its stores.
-
Tech Industry: A software company invests in scalable cloud infrastructure. As the number of users increases, the average cost per user decreases because the infrastructure cost is spread over a larger user base.
Frequently Asked Questions (FAQs)
Q1: What is the primary cause of decreasing costs?
A1: The primary causes include economies of scale, improved production techniques, advanced technology, and increased bargaining power for bulk purchasing.
Q2: Can decreasing costs be observed in all industries?
A2: While many industries can achieve decreasing costs, it is more prevalent in industries with high fixed costs and where production can be significantly scaled up.
Q3: How do decreasing costs impact a firm’s pricing strategy?
A3: Firms experiencing decreasing costs might lower prices to gain more market share or maintain prices and increase profit margins. The strategy chosen depends on the firm’s objectives and market conditions.
Q4: What are the limitations of economies of scale?
A4: The main limitations include diminishing returns to scale, where after a certain point, efficiency gains decrease, and increased complexity in managing larger operations.
Q5: How do decreasing costs affect competition?
A5: Firms with lower unit costs can offer lower prices, potentially driving competitors with higher costs out of the market. This can lead to increased market share for the cost-efficient firms.
- Economies of Scale: The cost advantage that arises with increased output of a product.
- Fixed Costs: Costs that do not change with the level of output.
- Variable Costs: Costs that vary directly with the level of production.
- Marginal Cost: The cost added by producing one additional unit of a product.
- Bulk Purchasing: Buying goods in large quantities, which often reduces the overall cost per unit.

Fundamentals of Decreasing Costs: Economics Basics Quiz
### What is the core reason behind the concept of decreasing costs?
- [x] Economies of scale
- [ ] Fixed costs increase
- [ ] Variable costs increase
- [ ] Decreased output volume
> **Explanation:** Economies of scale are the core reason behind decreasing costs, as they allow firms to reduce the cost per unit by increasing the volume of production.
### Which industry commonly experiences decreasing costs due to economies of scale?
- [x] Manufacturing
- [ ] Real estate
- [ ] Healthcare
- [ ] Legal services
> **Explanation:** The manufacturing industry often experiences decreasing costs due to economies of scale, as efficiency can be significantly increased with higher production volumes and automation.
### What is a critical factor in achieving decreasing costs in retail?
- [ ] Increasing prices
- [x] Bulk purchasing
- [ ] Reducing product range
- [ ] Decreasing store numbers
> **Explanation:** Bulk purchasing is a critical factor in achieving decreasing costs in retail, as it allows retailers to buy goods at lower prices due to volume discounts.
### Which term refers to the cost added by producing one more unit of a product?
- [x] Marginal Cost
- [ ] Fixed Cost
- [ ] Variable Cost
- [ ] Total Cost
> **Explanation:** Marginal cost refers to the additional cost incurred by producing one more unit of a product.
### What often remains unchanged despite increasing output?
- [ ] Marginal Cost
- [x] Fixed Costs
- [ ] Variable Costs
- [ ] Total Costs
> **Explanation:** Fixed costs typically remain unchanged despite increasing output, as they do not vary with the level of production.
### Why might a firm experiencing decreasing costs lower its prices?
- [ ] To reduce market share
- [x] To gain more market share
- [ ] To increase production costs
- [ ] To decrease competition
> **Explanation:** A firm might lower its prices to gain more market share, leveraging its reduced unit costs to attract more customers.
### At what point do the advantages of decreasing costs diminish?
- [x] Diminishing returns to scale
- [ ] Increasing variable costs
- [ ] Fixed cost saturation
- [ ] Output contraction
> **Explanation:** The advantages of decreasing costs diminish when diminishing returns to scale occur, as efficiency gains decrease beyond a certain point of production scale.
### What is the relationship between output volume and unit cost in the context of decreasing costs?
- [ ] Unit cost increases as output increases
- [x] Unit cost decreases as output increases
- [ ] Unit cost remains constant
- [ ] Unit cost fluctuates without a fixed pattern
> **Explanation:** In the context of decreasing costs, unit cost decreases as output volume increases due to economies of scale.
### What term describes cost savings achieved through increased bargaining power in bulk purchasing?
- [x] Economies of scale
- [ ] Fixed cost efficiency
- [ ] Variable cost savings
- [ ] Marginal return improvements
> **Explanation:** Cost savings achieved through increased bargaining power in bulk purchasing are part of economies of scale.
### Which of the following is a suggested book for further study on decreasing costs and economies of scale?
- [x] "Economics of Scale and Scope" by Panzar, John C
- [ ] "Legal Environmental Issues" by June Davis
- [ ] "Clinical Medicine" by G.H. Carr
- [ ] "Real Estate Principles" by Charles J. Jacobus
> **Explanation:** "Economics of Scale and Scope" by Panzar, John C is a suggested book for further study on decreasing costs and economies of scale.
