Chapter 11: Problem 3

What are economies of scale? What are four reasons that firms may experience economies of scale?

Short Answer

Expert verified
Economies of scale refer to the cost advantages a business obtains due to expansion. Four reasons for firms experiencing economies of scale could be: 1) Purchasing economies - the ability to negotiate better prices with suppliers, 2) Technical economies - efficiency of large-scale operations, 3) Financial economies - better loan or investment terms for larger firms due to lower risk, and 4) Managerial economies - benefits from specialization of labor and management.

Step by step solution

01

Definition

Economies of scale can be defined as the cost advantages that a business obtains due to expansion. It is a situation in which the cost per unit of output decreases with the increase in the scale of output.
02

Explanation of the first reason

The first reason could be Purchasing economies. When firms increase their scale, they buy more inputs, and this may enable them to negotiate for better prices from their suppliers.
03

Explanation of the second reason

The second reason could be Technical economies. As firms grow larger, they can take advantage of the increased efficiency of large-scale machines and processes.
04

Explanation of the third reason

The third reason could be Financial economies. Larger firms may get better interest rates or terms on loans or investments because lenders or investors see them as less risky.
05

Explanation of the fourth reason

The fourth reason could be Managerial economies. As firms grow, it is possible to hire specialized workers and managers, which can lead to increased efficiency and productivity.

Key Concepts

These are the key concepts you need to understand to accurately answer the question.

Cost Advantages
Economies of scale primarily result in cost advantages for businesses. This means as a company grows and produces more, its cost per unit decreases.
Imagine a factory making toys; as they produce more toys, their cost for each toy drops. Why? Well, a significant factor is fixed costs.
  • Fixed costs are things like rent or salaries that don't change with production levels.
  • As production increases, these fixed costs are spread over more units, lowering the cost per individual unit.
Moreover, variable costs also decrease due to efficiencies gained from large-scale production like bulk purchasing and streamlined processes. These cost advantages empower companies to offer competitive prices, ultimately benefiting consumers.
Purchasing Economies
Purchasing economies occur when firms get better prices on buying inputs. As companies expand and buy in bulk, they often secure discounts or better terms from suppliers.
Think of it like shopping at a wholesale club versus a regular store. At the wholesale club, you buy in larger quantities but pay less per item.
  • Buying in large volumes opens up opportunities for negotiations with suppliers.
  • Firms may obtain bulk discounts, reducing the cost of materials or products.
This leverage in negotiation leads to lower costs and higher profit margins, giving businesses a competitive edge.
Technical Economies
Technical economies arise from increased efficiency using advanced technology and large-scale operations. As firms grow, they can afford and justify investing in high-tech, efficient equipment.
Picture a small bakery using hand mixers versus a massive automated bakery line.
  • Large-scale machinery often operates at higher efficiency with greater output.
  • Automation reduces labor needs and minimizes human error.
By maximizing technology and processes, firms cut costs and increase productivity, enhancing their competitive position.
Financial Economies
Financial economies are advantages larger firms have due to better financial terms and access. As businesses grow, they are seen as more stable and reliable, attracting investments.
Consider how banks treat large corporations versus small businesses.
  • Lenders often offer larger firms lower interest rates on credit and loans because they present lower risk.
  • Big companies can offer more collateral and may have established relationships with financial institutions.
This access to favorable financial terms enables further growth and investments in business expansions.
Managerial Economies
Managerial economies stem from employing specialized managers and staff as firms expand. A growing company has more resources to hire talent and optimize management practices.
Consider a small startup versus a multi-department corporation.
  • Specialized managers bring expertise, enhancing decision-making and operations.
  • Efficiency and productivity increase as tasks are delegated to individuals with specific skill sets.
This specialization enhances overall business performance, meeting objectives efficiently while promoting growth.

A writer for the Wall Street Journal, discussing the relatively poor performance of \(\mathrm{HSBC},\) a global bank with headquarters in the United Kingdom, noted, " [The poor performance] is further reason to ask whether the structure of such a large, global bank is working against it.... There remains a legitimate question whether the group is too big to manage." After reading this article, a student remarks: "It seems that the firm is suffering from diminishing returns." Briefly explain whether you agree with this remark.

Is it possible for average total cost to be decreasing over a range of output where marginal cost is increasing? Briefly explain.

We saw in the chapter opener that some colleges and private companies have launched online courses that anyone with an Internet connection can take. The most successful of these massive open online courses (MOOCs) have attracted tens of thousands of students. Suppose that your college offers a MOOC and spends a total of \(\$ 200,000\) on one-time costs to have instructors prepare the course material and buy additional server capacity. The college administration estimates that the variable cost of offering the course will be \(\$ 20\) per student per course. This variable cost is the same, regardless of how many students enroll in the course. a. Use this information to fill in the missing values in the following table: $$ \begin{array}{c|c|c|c|c} \hline \text { Number of } & & \\ \begin{array}{c} \text { Students } \\ \text { Taking the } \\ \text { Course } \end{array} & \begin{array}{c} \text { Average } \\ \text { Total Cost } \end{array} & \begin{array}{c} \text { Average } \\ \text { Variable } \\ \text { Cost } \end{array} & \begin{array}{c} \text { Average } \\ \text { Fixed Cost } \end{array} & \begin{array}{c} \text { Marginal } \\ \text { Cost } \end{array} \\ \hline 1,000 & & & & \\ \hline 10,000 & & & & \\ \hline 20,000 & & & & \\ \hline \end{array} $$ b. Use your answer to part (a) to draw a cost curve graph to illustrate your college's costs of offering this course. Your graph should measure cost on the vertical axis and the quantity of students taking the course on the horizontal axis. Be sure your graph contains the following curves: average total cost, average variable cost, average fixed cost, and marginal cost.

Which of the following are examples of a firm experiencing positive technological change? a. A fall in the wages JetBlue pays its mechanics leads it to lower its ticket prices. b. A training program makes a firm's workers more productive. c. An exercise program makes a firm's workers healthier and reduces the number of days the typical worker is absent. d. A firm cuts its workforce and is able to maintain its initial level of output. e. A firm rearranges the layout of its factory and finds that by using its initial set of inputs, it can produce exactly as much as before.
