Which statement best differentiates economies of scale and economies of scope?

• A. Economies of scale are cost advantages from increased production of a single product; economies of scope arise when producing multiple products together reduces average costs due to shared resources.
• B. Economies of scale arise from joint production of multiple products; economies of scope arise from increasing output of one product.
• C. Economies of scale and economies of scope are the same concept; there is no meaningful difference.
• D. Economies of scale relate only to labor costs, while economies of scope relate only to capital costs.

Answer: (A)

The idea being tested is how cost advantages arise from different production choices: producing more of one product versus producing multiple products together. Economies of scale occur when increasing the output of a single product lowers the average cost per unit, mainly because fixed costs are spread over more units and efficiency improves with larger volumes. Economies of scope occur when producing several different products in combination lowers the average total cost because shared inputs or capabilities—like machinery, distribution networks, or managerial expertise—are used across products. That makes the best statement the one that says economies of scale come from higher production of a single product, while economies of scope come from producing multiple products together to share resources and reduce costs. For example, a car factory becomes cheaper per car as it builds more cars (scale). A company that makes both cars and car parts using the same factory might lower costs overall by sharing equipment and labor (scope). The other ideas mix up the distinctions: treating joint production of multiple products as economies of scale, or claiming they are the same concept, or tying scale to labor costs and scope to capital costs, would not accurately reflect how these cost advantages arise.
