What Is Economies of Scope?

Economies of scope refers to the cost advantages that arise when a business produces a variety of products or services together rather than producing each one separately. It is a fundamental concept within microeconomics and business strategy. These cost savings occur because the joint production of multiple goods allows for the more efficient utilization of shared resources, capabilities, or processes across different product lines. For instance, a company might use the same manufacturing facility, distribution channels, or marketing efforts for several different products, thereby spreading fixed costs and lowering the overall average cost per unit across its diversified offerings.³⁹, ⁴⁰

History and Origin

The concept of economies of scope gained prominence in economic theory in the late 1970s and early 1980s, notably through the work of economists John C. Panzar and Robert D. Willig. Their contributions helped formalize the idea that cost efficiencies could be achieved through variety, not just volume, of production. The theoretical underpinnings of the multi-product firm, which is inherently linked to economies of scope, were further explored in academic papers, such as David J. Teece's 1982 work, "Towards an Economic Theory of the Multiproduct Firm".³⁸

Beyond theoretical development, the historical significance of economies of scope was extensively documented by business historian Alfred D. Chandler Jr. In his seminal 1990 book, Scale and Scope: The Dynamics of Industrial Capitalism, Chandler argued that the ability of large American corporations to integrate and coordinate diverse business activities to exploit both economies of scale and economies of scope was crucial to their rise and sustained competitive advantage in the 20th century.³⁶, ³⁷ He detailed how companies made strategic investments in new production technologies and widespread distribution networks to capitalize on producing multiple goods from similar materials or with shared labor, thereby reducing costs.³⁵

Key Takeaways

• Cost Efficiency: Economies of scope enable businesses to achieve cost savings by producing a wider range of products or services collectively, rather than individually.³⁴
• Resource Sharing: The primary mechanism for economies of scope is the shared use of resources such as technology, production facilities, distribution channels, and marketing expertise across multiple product lines.³¹, ³², ³³
• Diversification Benefits: Leveraging economies of scope can support a company's diversification strategy, allowing it to reduce dependence on a single product and potentially increase market share.²⁹, ³⁰
• Competitive Edge: By lowering per-unit costs and offering a broader product portfolio, companies can gain a significant competitive advantage in the marketplace.²⁷, ²⁸
• Synergistic Effects: The simultaneous production of complementary goods or services often creates synergy, where the combined value or efficiency is greater than the sum of their individual parts.²⁶

Formula and Calculation

Economies of scope exist when the total cost of producing two or more distinct products or services together is less than the sum of producing each product or service separately. The degree of economies of scope (DSC) can be represented by the following formula:

Where:

• ( S ) represents the degree of economies of scope. A value greater than 0 indicates economies of scope.
• ( C(Q_1) ) is the cost of producing quantity ( Q_1 ) of product 1 alone.
• ( C(Q_2) ) is the cost of producing quantity ( Q_2 ) of product 2 alone.
• ( C(Q_1, Q_2) ) is the cost of producing quantities ( Q_1 ) and ( Q_2 ) of both products together.²⁵

If ( S > 0 ), economies of scope exist, implying that joint production is more cost-effective. If ( S < 0 ), diseconomies of scope are present, suggesting that separate production would be more efficient.

Interpreting the Economies of Scope

Interpreting economies of scope involves understanding how integrated operations lead to cost efficiencies. When a firm exhibits positive economies of scope, it means that the incremental cost of adding a new, related product to its existing production line is less than what it would cost a standalone firm to produce that new product.²⁴ This often stems from shared infrastructure, common inputs, or transferable knowledge.

For example, a technology company that already manufactures smartphones can often introduce smartwatches or tablets to its product portfolio with a relatively lower additional cost compared to a new entrant. This is because they can leverage existing research and development, manufacturing facilities, and supply chain networks.²³ Effective resource allocation across these varied products is key to realizing these benefits.

Hypothetical Example

Consider "FlavorFusion," a hypothetical food company that initially produces only organic fruit juices. FlavorFusion has invested significantly in a juicing plant, a bottling line, and a distribution network tailored for perishable liquid goods. They notice that their juicing plant sometimes operates below full capacity.

To leverage economies of scope, FlavorFusion decides to introduce organic fruit purees for baby food. This new product development allows them to use the same fruit suppliers, the same juicing equipment (with minor modifications for puree consistency), and the same cold storage facilities already in place. The bottling line can be adapted for smaller puree jars. Furthermore, their existing distribution network can deliver both juices and purees to grocery stores and health food shops. By sharing these resources, the total cost of producing both juices and purees together is significantly lower than if FlavorFusion were to set up a separate operation for purees, or if a different company produced only purees.

Practical Applications

Economies of scope are widely observed across various industries, underpinning many corporate strategies and structures.

• Consumer Goods: Companies like Procter & Gamble effectively utilize economies of scope by sharing marketing campaigns and distribution channels across a vast array of personal care and household products. This allows them to reach a wide customer base efficiently.²²
• Financial Services: Banks often offer a wide range of services including checking accounts, loans, credit cards, and investment products. They leverage their existing branch networks, customer databases, and regulatory compliance infrastructure to deliver these diverse financial products, making it more cost-effective than offering each service through separate entities.
• Media and Entertainment: A media conglomerate might produce movies, television shows, and streaming content, sharing production studios, creative talent, and distribution platforms (e.g., streaming services) to reduce costs and maximize audience reach. The strategic use of product bundling also frequently arises from efforts to capture economies of scope.
• Transportation: Airlines often carry both passengers and freight on the same flights, optimizing the use of aircraft, fuel, and flight crews already in place for passenger services. This exemplifies a classic application of economies of scope in action.²⁰, ²¹

These applications highlight how firms can expand their offerings and increase their profitability by maximizing the utility of their existing assets and capabilities.

Limitations and Criticisms

While economies of scope offer significant advantages, they also come with potential drawbacks and criticisms. The pursuit of diversification can sometimes lead to diseconomies of scope, where expanding into new product lines or businesses actually increases costs or creates inefficiencies instead of reducing them.¹⁹

One major limitation is the increased complexity and coordination challenges that arise from managing a diverse portfolio of products or services. Different product lines may require distinct management skills, marketing approaches, or operational processes, which can strain an organization's resources and managerial capacity.¹⁷, ¹⁸ For example, integrating vastly different business units acquired through mergers and acquisitions can be challenging, potentially leading to a lack of focus or reduced overall performance. Professor Michael Roberto highlights how the expansion of scope can sometimes harm a company's brand image or diminish the value of its existing businesses, citing examples like Citigroup's diversification across private banking, investment banking, and insurance.¹⁶

Furthermore, the assumed "synergies" may not always materialize as expected. Overestimating the benefits or underestimating the costs of integrating diverse operations can lead to poor investment decisions. In some cases, the benefits of shared resources might be limited if the products or services are not sufficiently complementary, or if the costs of adapting existing resources for new uses outweigh the potential savings.¹⁵

Economies of Scope vs. Economies of Scale

Economies of scope and economies of scale are both concepts describing cost efficiencies, but they stem from different sources. The key distinction lies in whether the cost savings come from producing more of the same product or from producing a variety of products.

While distinct, these two concepts are not mutually exclusive. Many large corporations strive to achieve both economies of scale in the production of their core products and economies of scope by expanding their product lines.

FAQs

What causes economies of scope?

Economies of scope are primarily caused by the efficient sharing of common resources and capabilities across the production of multiple products or services. This includes sharing production facilities, distribution networks, research and development (R&D) efforts, marketing campaigns, and management expertise.⁴, ⁵

How do economies of scope benefit a business?

Economies of scope benefit a business by reducing the overall average cost of production, which can lead to increased profitability and a stronger competitive advantage. They allow companies to diversify their revenue streams, respond more flexibly to market changes, and leverage existing investments more effectively.², ³

Can small businesses achieve economies of scope?

Yes, small businesses can achieve economies of scope, though perhaps on a smaller scale than large corporations. For instance, a local bakery might produce a variety of bread, pastries, and cakes using the same oven and staff. A freelance designer might offer both web design and graphic design services, using similar software and creative skills. The core principle of utilizing existing resources more broadly for cost savings applies to businesses of all sizes.

What is the relationship between economies of scope and product diversification?

Economies of scope are a key driver and enabler of product development. They provide a strong economic rationale for companies to expand their product offerings, as the cost efficiencies gained through shared resources make it financially attractive to introduce new, related goods or services. This allows firms to grow and potentially capture a larger market share.

Is there a downside to pursuing economies of scope?

Yes, there can be downsides. If the products are not sufficiently complementary, or if managing the expanded scope becomes too complex, a company might experience diseconomies of scope. This can lead to increased coordination costs, diluted management focus, and a loss of efficiency, ultimately offsetting the potential benefits.¹
