Economies of scope is an economic theory that reflects the cost advantages a business can achieve by producing a wide variety of products instead of specializing in just one product or service. This concept is closely related to, but distinct from, economies of scale[1], which pertains to cost benefits gained from increasing production volume of a single product. Economies of scope are often demonstrated in industries with high joint costs, such as cable networks and airlines, where the same resources can be used to deliver different services. It plays a key role in natural monopolies and has significant implications for a company’s product design[2], response to market changes, cost predictability, and risk reduction. The theory contributes to overall economic efficiency and supports strategies such as mass customization and optimal cost structures.
Economias de gama are "efficiencies formed by variety, not volume" (the latter concept is "economies of scale"). In economics, "economies" is synonymous with cost savings and "scope" is synonymous with broadening production/services through diversified products. Economies of scope is an economic theory stating that average total cost of production decrease as a result of increasing the number of different goods produced. For example, a gas station that sells gasoline can sell soda, milk, baked goods, etc. through their customer service representatives and thus gasoline companies achieve economies of scope.
