What occurs as a firm increases its size of operation regarding costs?

As a firm increases its size of operation, average costs generally decrease due to the advantages of economies of scale. When a firm expands, it can spread its fixed costs, such as administrative expenses, over a larger output, which reduces the average cost per unit. Additionally, larger firms may benefit from operational efficiencies, bulk purchasing of materials at lower prices, specialized labor, and optimized production processes. These factors contribute to a decline in average costs as the scale of production grows, making the firm more competitive in its market.

Understanding this concept is crucial for firms as they plan their growth strategies, allowing them to optimize operations and maintain profitability while scaling.
