5 External Diseconomies of Scale External diseconomies of scale are by Jerry Grzegorzek

All firms in a particular industry receive equal access to the benefits of external economies of scale. External diseconomies of scale are diseconomies of scale that occur within the industry (outside the firm) and are largely beyond an individual firm’s control. Larger businesses can isolate employees and make them feel less appreciated, which can result in a drop in productivity. Technical diseconomies of scale involve physical limits on handling and combining inputs and goods in process. These can include overcrowding and mismatches between the feasible scale or speed of different inputs and processes.

Returns are decreasing if, say, doubling inputs results in less than double the output, and increasing if more than double the output. If a mathematical function is used to represent the production function, and if that production function is homogeneous, returns to scale are represented by the degree of homogeneity of the function. Homogeneous production functions with constant returns to scale are first degree homogeneous, increasing returns to scale are represented by degrees of homogeneity greater than one, and decreasing returns to scale by degrees of homogeneity less than one. Firms might be able to lower average costs by buying the inputs required for the production process in bulk or from special wholesalers. By negotiating with suppliers for volume discounts, the purchasing firm takes advantage of economies of scale.

External economies of scale can be achieved a number of different ways. Technological advancements may drive down production costs for an entire industry, as can government support in the form of infrastructure investments or tax subsidies. In economics, economies of scale dictate that the more units a business produces, the less it costs to produce each unit. Any industry-wide effects that make it more difficult or more costly to perform business operations is called an external diseconomy of scale.

Additional Resources

1. Some economies of scale, such as capital cost of manufacturing facilities and friction loss of transportation and industrial equipment, have a physical or engineering basis.
2. For instance, a firm might be able to implement certain economies of scale in its marketing division if it increased output.
3. Internal economies of scale are different from external ones since the former include factors that are unique to an individual firm.
4. In other words, it is the point at which economies of scale are fully realized, and any further increase in production would result in diseconomies of scale.
5. Each of these factors reduces the long run average costs (LRAC) of production by shifting the short-run average total cost (SRATC) curve down and to the right.

A similar example is the depletion of a critical natural resource below its ability to reproduce itself in a tragedy of the commons scenario. As the resource becomes ever more scarce and ultimately external diseconomies of scale runs out, the cost to obtain it increases dramatically. Many manufacturing facilities, especially those making bulk materials like chemicals, refined petroleum products, cement and paper, have labor requirements that are not greatly influenced by changes in plant capacity. Firms might be able to lower average costs by improving the management structure within the firm. For instance, a firm may hold a patent over a mass production machine, which allows it to lower its average cost of production more than other firms in the industry.

3. The graph above plots the long-run average costs (LRAC) faced by a firm against its level of output.
4. In economics, a key result that emerges from the analysis of the production process is that a profit-maximizing firm always produces that level of output which results in the lowest average cost per unit of output.
5. These factors are typically referred to as positive externalities; industry-level negative externalities are called external diseconomies.
6. A production function has constant returns to scale if increasing all inputs by some proportion results in output increasing by that same proportion.

Large producers are usually efficient at long runs of a product grade (a commodity) and find it costly to switch grades frequently. They will, therefore, avoid specialty grades even though they have higher margins. Often smaller (usually older) manufacturing facilities remain viable by changing from commodity-grade production to specialty products.3a Economies of scale must be distinguished from economies stemming from an increase in the production of a given plant.

Internal Economies of Scale

Sometimes, diseconomies of scale happen within an organization when a company’s plant cannot produce the same quantity of output as another related plant. For example, if a product is made up of two components, gadget A and gadget B, diseconomies of scale might occur if gadget B is produced at a slower rate than gadget A. This forces the company to slow the production rate of gadget A, increasing its per-unit cost. External economies of scale refer to the phenomenon in which production costs fall for all firms in a certain sector. This is different from economies of scale as the idea is commonly understood, in which production costs decline for a single company.

A technological advancement might drastically change the production process. For instance, fracking completely changed the oil industry a few years ago. However, only large oil firms that could afford to invest in expensive fracking equipment could take advantage of the new technology. Firms that operate below their MES may not be able to compete effectively due to higher production costs, while those operating above it may experience inefficiencies and increased costs.

The elimination of discriminatory pricing ensures that no firm pays a higher amount for inputs, and it reduces the overall average cost. External diseconomies of scale can arise due to constraints imposed by the environment within which a firm or industry operates. Essentially, diseconomies of scale are the result of the growing pains of a company after it’s already realized the cost-reducing benefits of economies of scale.

Firm X can reduce its average cost of production by $11 if it sets up its premises near the cluster. A common error made by students is asserting that production costs will fall as output increases. A firm needs continuous information from the industry like the cost of the inputs, products, policies, and other services are required by the organization. If two or more separate industries are incidentally beneficial to one another, there can be external economies of scale across the entire group. This phenomenon is sometimes called an “agglomeration economy,” in which businesses are located close to one another and can share resources and efficiencies.

Growth of supporting industries

If a particular firm formulates a technique of production that saves time and cost, then the benefit is internal to the firm and will not impact other firms in the industry. Price inelasticity of supply for key inputs traded on a market is a related cause of diseconomies of scale. In this case, if a firm attempts to increase output, it will need to purchase more inputs, but price inelastic inputs will mean rapidly increasing input costs out of proportion to the increase in the amount of output realized. Thus, firms employing less than 10,000 workers can potentially lower their average cost of production by employing more workers. This is an example of an external economy of scale – one that affects an entire industry or sector of the economy.

The graph above plots the long-run average costs (LRAC) faced by a firm against its level of output. When the firm expands its output from Q1 to Q2, its average cost falls from C1 to C2. Thus, the firm can be said to experience economies of scale up to output level Q2. When the government of a country offers tax concessions on the production of a certain product or subsidies on the purchase of certain raw materials, it reduces the cost of production of all firms in that particular industry.

It makes sense for industries to concentrate in areas where they are already strong. For example, a film studio might determine that California is a particularly good location for year-round film-making, so it moves to Hollywood. New movie producers also move to Hollywood because there are more camera operators, actors, costume designers, and screenwriters in the area. Then, more studios might decide to move to Hollywood to take advantage of the specialized labor and infrastructure already in place, thanks to the success of the first firm. Likewise, an external diseconomy (negative externality) occurs when a person or business imposes some cost or hardship on others without having to (or being able to) compensate them. The classic example is a factory that has a smokestack that is dirtying the property of those living nearby.
