Economies and Diseconomies of Scale

Jojo owns a small bakery.
As your business grows, Jojo discovers that buying ingredients in bulk reduces costs, and investing in specialized equipment speeds up production.
However, as Jojo expands further, communication issues arise, and managing a larger team becomes challenging.

This journey illustrates economies of scale and diseconomies of scale, two critical concepts in business growth.

Economies of Scale: Lowering Costs as You Grow

Definition

Economies of scale

Economies of scale occur when a business's average cost per unit decreases as its production scale increases.

Internal Economies of Scale

Internal economies of scale occur due to factors within the business, leading to increased efficiency and reduced costs.

Example

Cost savings that result from factors inside the business, such as improved production techniques, bulk purchasing, or specialized labor.

1. Automatic Production

Using automated production processes increases efficiency and reduces labor costs, lowering the cost per unit.

Example

A car manufacturer might use robotic assembly lines to produce vehicles more efficiently.

2. Purchasing Economies

Buying raw materials in bulk often leads to discounts, reducing the cost per unit.

Example

Walmart leverages its size to negotiate lower prices from suppliers.

3. Managerial Economies

Larger businesses can hire specialized managers, improving efficiency and decision-making.

Example

A dedicated finance manager might optimize tax strategies, reducing overall costs.

4. Financial Economies

Big firms often secure loans at lower interest rates because they are seen as less risky by lenders.

Example

A multinational corporation can borrow money more cheaply than a small startup.
