Increasing marginal costs eventually cause increasing average costs and make it more difficult to compute break-even prices. When negotiating contracts, it is important to know what your costs curves look like; otherwise, you could end up accepting contracts with unprofitable prices.

If average cost falls with output, then you have increasing returns to scale. In this case you want to focus strategy on securing sales that enable you to realize lower costs. Alternatively, if you offer suppliers big orders that allow them to realize economies of scale, try to share in their profit by demanding lower prices. 2 ©2018 Cengage Learning. All Rights Reserved.

If average costs rise with output, you have decreasing returns to scale or diseconomies of scale. Learning curves mean that current production lowers future costs. It’s important to look over the life cycle of a product when working with products characterized by learning curves. If the cost of producing two outputs jointly is less than the cost of producing them separately — that is Cost(Q1,Q2) < Cost(Q1) + Cost(Q20) — then there are economies of scope between the two products.

This can be an important source of competitive advantage and shape acquisition strategy. 3 continued ©2018 Cengage Learning. All Rights Reserved.

In 1996, The Thomas H.

Lee Company acquired Rayovac – taking advantage of easy credit availability the company then bought many other battery production companies as well. A move the company said they made to take advantage of efficiencies and economies of scale. They expected that as they produced more of the same good, average costs would fall. The company also bought many unrelated companies at the same time as the battery binge – the reasoning being that because of synergies, if they centralized the production of many different goods the costs of production would be lower. By February 2009 the new conglomerate was bankrupt Moral of the story?

In business investments if you hear the words “efficiency†or “synergy,†hold on to your money. 4 ©2018 Cengage Learning. All Rights Reserved.

Example: Akio Morita and the Sony Transistor radio In 1955, Akio Morita found a retailer that would sell his .95 transistor radio under his “Sony†brand name The problem: the retailer wanted to buy 100,000 for its 150 stores, 10 times more than Mr. Morita’s capacity. Mr.

Morita had to turn down the offer He knew that he would lose money producing 100,000 units because increasing output would require hiring/training more workers and an expansion of facilities This would raise his average costs. The retailer agreed to settle for 10,000 units, the rest is history Lesson: know what your costs look like! 8 ©2018 Cengage Learning. All Rights Reserved.

Understanding the Economies of Scale and Scope

Economies of scale and scale, as fundamental concepts in economics, describe how the average cost of production changes as the scale of production increases. When understanding these concepts, it is essential to consider how they affect business strategy, operational efficiency, and pricing decisions.

Economies of Scale

Definition and Types
Economies of scale refer to the cost advantages that a business obtains due to the scale of operation, with cost per unit of output generally decreasing with increasing scale as fixed costs are spread out over more units of output. They can be categorized into three types:
1. Internal Economies of Scale: Cost benefits arising from internal factors such as more efficient production techniques or better utilization of labor (Mankiw, 2017).
2. External Economies of Scale: Cost advantages that accrue to all firms in an industry as the industry grows, such as improved infrastructure and increased skilled labor (Koot, 2019).
3. Constant and Decreasing Returns to Scale: If average costs stay constant as output increases, then it is constant returns. If they increase, it indicates decreasing returns, often due to inefficiencies creeping into the production process (Samuelson & Nordhaus, 2010).
Graphical Representation
When plotted on a graph, the average cost curve typically slopes downwards at first, representing increasing returns to scale, then flattens out, and may eventually rise, indicating decreasing returns to scale (Tucker, 2020). Understanding these curves is crucial for determining the optimal production level.
Examples of Economies of Scale
The poultry industry provides a prime example of economies of scale, where advances in technology have allowed large processing plants to operate more efficiently (Economist, 2020). More broadly, companies like Rayovac have sought to consolidate and increase production volumes to drive down costs but must be cautious of overspending and operational inefficiencies that can result from rapid expansion (Cengage Learning, 2018).

Economies of Scope

Definition
Economies of scope refer to the cost advantages that enterprises obtain by producing multiple products together rather than separately. If the cost of producing two outputs jointly is less than the cost of producing them separately, economies of scope exist (Pindyck & Rubinfield, 2013).
Importance in Business Strategy
Economies of scope can be leveraged to create competitive advantages. Companies may merge or acquire others to provide a larger portfolio of products, thus enjoying reduced costs through shared resources or market strategies (Hitt et al., 2017). For instance, major companies like Kraft and ConAgra enjoy economies of scope by packaging and distributing multiple products together, lowering distribution and marketing costs (Cengage Learning, 2018).
Examples of Economies of Scope
The production of guitar fingerboards exemplifies economies of scope, where different grades of wood—such as rosewood for budget guitars and ebony for high-end models—are used to produce complementary products. The ability to leverage lower-quality materials to produce accessible instruments helps companies maintain profitability across diverse product lines (Smith et al., 2018).

Learning Curves

Learning curves indicate that every time an organization produces more of a product, it learns and improves its processes, thereby reducing costs for future production (Nadler, 2016). For example, in aerospace manufacturing, when production doubles, marginal costs may drop, allowing for more competitive pricing (Cengage Learning, 2018).

Marginal Costs and Pricing Strategies

Understanding the relationship between average costs, marginal costs, and break-even pricing is essential for businesses (Pignataro, 2020). For instance, if a company begins its production at a high average cost of per unit and manages to cut this to by refining its operations, the business must strategically set prices to ensure margin sustainability across the production lifecycle.

Risks and Misconceptions

While aiming for economies of scale and scope can be beneficial, pitfalls exist. Rapid expansion without careful consideration can lead to increased complexities and costs, as seen in the case of Rayovac, which faced bankruptcy following aggressive expansions that ignored the cost implications ("Economies of Scale and Scope: A Raw Deal," 2014). Merging under the assumption that larger operations will always yield reduced costs often leads to diseconomies of scale if not managed properly (Mukherjee, 2020).

Conclusion

Achieving economies of scale and scope requires an insightful understanding of production processes, market demands, and cost structures. Businesses must be strategic about growth to ensure that increased production does not lead to diminishing returns. Emphasizing the critical balance between optimizing production methods and managing costs can lead to enhanced competitiveness and profitability in the market.
