Production of Goods and Services

Get ready to step into the world of real business decisions! In this section, you will learn how firms grow or face challenges through economies and diseconomies of scale, discover how firms and industries reach equilibrium, explore different business objectives and examine how price discrimination operates in real markets. You have already explored how businesses choose where to locate, how they organise their resources and what makes production efficient. You have tackled ideas like the factors of production, specialisation and how costs and revenues affect decision-making. All of these give you the tools to understand how real firms grow, compete and sometimes struggle in the market. Now it is time to bring everything together and see how firms make smart (or risky) decisions in real markets using what you have learned!

KEY IDEAS

• A firm is in equilibrium when it produces at an output level where marginal cost equals marginal revenue, and it has no incentive to adjust production, even if it’s earning zero, positive, or negative profit.

• An industry reaches equilibrium when the total amount producers are willing to supply matches the amount consumers want to buy at the market price.

• Comparing economies and diseconomies of scale helps firms decide the ideal size for growth by weighing cost savings against rising costs from growing too large.

• Economies and diseconomies of scale show how increasing a firm’s output can either reduce or raise average costs depending on how growth is managed.

• Firms set different goals such as making profits, expanding operations or gaining market leadership based on their overall business objectives.

• Price discrimination is when a firm charges different customers different prices for the same product based on factors like time, income or location.

Economies of scale are the cost advantages a business enjoys when it increases production. As a firm produces more goods, the average cost per unit decreases. This happens because some costs, such as rent, salaries or electricity, among others, are spread across increasing outputs. This simply means that when a business grows and produces more, it becomes cheaper to produce each product if the business is managed properly.

Types of Economies of Scale

As a business grows, it can enjoy lower costs per unit. These cost savings are called economies of scale, and they can come from within the business (internal) or from outside (external).

1. Internal Economies of Scale

Internal economies of scale are cost advantages or cost savings enjoyed by a firm as a result of an increase in its scale of production, arising from factors within the firm. As the firm expands, it becomes more efficient and reduces its average cost of production.

These cost advantages that come from within the firm include:

a. Technical Economies Big firms can afford better machines and technology, which help them produce faster and at a lower cost. For example, Ghacem, a large cement company in Ghana, uses advanced equipment that small cement producers in Ghana cannot afford.

b. Managerial Economies Large companies can hire specialists and experts to handle different departments like finance, production or marketing. This improves efficiency. For example, Unilever Ghana employs professionals to manage its operations efficiently.

c. Purchasing Economies Big firms buy raw materials in bulk, which helps them get discounts from suppliers.

For example, Kasapreko, a beverage company, buys bottles, caps and labels in large quantities at lower prices.

d. Marketing Economies Larger businesses can advertise to a wider audience at a lower cost per customer.

For example, MTN Ghana can run nationwide ads, while a small network provider in Ho may only advertise locally and spend more to reach a consumer.

e. Financial Economies Banks trust bigger and stable firms more than smaller firms and as a result, they offer loans with low interest rates to the bigger firms. For example, GCB Bank can give loans at cheaper interest rates to Kasapreko Company Limited than a small clothing shop in Kumasi because Kasapreko Company is seen as more reliable.

f. Welfare economies A large firm can provide better working conditions for its workers, such as good salaries, health services, and safe workplaces. This improves worker motivation and productivity, which reduces the cost of production.

g. Research economies Big firms can afford to invest in research and development. This helps them discover new methods of production, improve product quality, and reduce waste, leading to lower costs.

2. External Economies of scale External economies of scale are cost savings advantages that come from outside the firm. These happen when many firms are in the same industry or located in the same area.

Examples in Ghana:

a. Pool of skilled labour When many firms in the same field operate in the same area, it is easy to hire skilled workers. This will reduce the training cost of companies.

For example, in Suame Magazine (Kumasi), where many vehicle repair shops are located, mechanics are always available, so businesses save time and training costs.

b. There is shared infrastructure Firms in the same area can share roads, water, electricity and storage, reducing individual costs.

For example, in an agro-processing zone in the Eastern Region, different food- processing companies use the same power supply and storage facilities.

c. Support Services Nearby services such as transport, repairs and suppliers help businesses operate more cheaply and efficiently. For example, on Spintex Road in Accra, many businesses benefit from being close to delivery vans, ICT technicians, packaging suppliers and printing presses.

Scenario A small sachet water producer in Accra begins by producing 2,000 sachets per day using a manual sealing machine. As sales increase, the owner invests in a high-speed automatic machine and starts producing 20,000 sachets daily. They now buy water treatment chemicals and packaging in bulk at a discount and share distribution trucks with two nearby producers.

The cost per sachet drops. This is an example of economies of scale.

Key Benefits of Economies of Scale

Type of Economy Benefit

Technical Nestlé Ghana uses automated machines to produce more milk tins at a lower cost.

Managerial Voltic hires specialists to improve efficiency and reduce waste.

Purchasing A large cocoa exporter buys sacks in bulk at lower prices.

Marketing Vodafone runs a nationwide ad campaign, reducing the cost per customer reached.

Financial A large company gets cheaper loans than a small, unknown business.

External (Infrastructure) Businesses at Tema Port benefit from shared transport networks.

Activity 3.1Bottom of Form Recap on Production of Goods and Services Purpose: The purpose of this activity is to help you connect Year One and Year Two production concepts through a real Ghanaian business story and practice collaborative discussion skills.

Instructions: Work in groups of 4-5 learners.

Read the scenario together and discuss each question as a group.

Prepare short answers to the questions in your notebook.

Each group will share one response with the class.

Scenario: Adinkra Textiles- A Ghanaian

Success Story.

Adinkra Textiles is a family-owned business in Kumasi that has grown from a small home-based operation to a successful textile company over the past decade.

When Kofi started the business five years ago, he used his savings (capital), rented a small workshop (land), hired three skilled weavers (labour) and took on the role of manager (entrepreneurship). He paid rent for the workshop, wages to the weavers, interest on a small loan and kept the remaining profit.

Kofi chose Kumasi because of its proximity to cotton suppliers and the large market for textiles. Initially, each weaver made complete cloth pieces alone, but productivity was low.

As demand increased, Kofi introduced division of labour - one weaver focused on spinning, another on dyeing and the third on weaving patterns. This specialisation dramatically increased their daily output from 5 pieces to 15 pieces of cloth.

Page 1 Today, Adinkra Textiles operates differently based on time periods. In the short run, they can hire more temporary weavers during festival seasons but cannot expand their workshop space. However, in the long run, they plan to build a larger factory and purchase modern looms.

The business now tracks costs carefully.

They pay GH¢2,000 monthly rent (which stays the same regardless of production), GH¢50 per cloth for materials and temporary labour (which increases with each cloth produced), making their total monthly cost the sum of both fixed and variable expenses.

When they sell 100 pieces at GH¢80 each, they earn GH¢8,000 in total revenue.

The average revenue per piece is GH¢80 and if they sell one additional piece, their marginal revenue increases by GH¢80.

Page 2 Discussion questions

1. What are the four factors of production Kofi used, and what reward does each factor receive?

2. How did introducing specialisation change the productivity at Adinkra Textiles?

3. Why do you think Kofi chose Kumasi as the location for his textile business?

4. Give one example each of what Adinkra Textiles can change in the short run versus the long run.

5. If Adinkra Textiles produces 50 pieces of cloth in a month, what would their total cost be? [Show your calculation using the formula Total Cost = Fixed Costs + (Variable Cost per Unit × Quantity Produced)]

6. If Adinkra Textiles wants to calculate how much additional revenue they earn from selling one more piece of cloth, which type of revenue concept should they use?

Closure: As a group, share one of your answers with the class.

Step 4: Class Synthesis

a. Highlight connections between internal/external economies.

b. Relate your findings to the Ghanaian business context.

Diseconomies of scale happen when a business expands too large and its average cost per unit increases. This means the business is no longer enjoying a reduction in cost from expansion. Instead, the cost of producing each unit becomes more expensive.

In simple economic terms, as a company expands beyond a certain level, it faces new problems like poor management, low worker motivation and communication issues.

This makes production expensive.

Types of Diseconomies of Scale

₁. Internal Diseconomies of Scale These are the disadvantages that occur within the firm when it becomes too big. They include the following:

a. Managerial Diseconomies When a business grows, it employs more managers and creates more departments.

This can cause slow decision-making and increase the costs of management. For

example, a large cocoa processing factory in Tema and branches in other areas, such as Takoradi and Kumasi, may have too many managers. When one branch wants to make a change, it must wait for approval from other branches. This delays production and increases costs.

b. Labour Diseconomies In large companies, workers may feel ignored or less motivated. This can lead to low productivity, more mistakes and higher costs. For example, at a big clothing factory in Accra, workers feel like no one notices their efforts. They lose interest, work slowly and make more errors. The company then spends more money fixing those mistakes.

c. Technical Diseconomies Large businesses often use complex machines that are connected to other machines. If one machine breaks down, it can stop the whole production process and increase repair and maintenance costs. For example, a cement company in Takoradi depends on one large machine. When it breaks, the entire factory shuts down. This increases the cost of repairs and maintenance for the company.

d. Communication Diseconomies As firms grow, they may have many offices and departments. This makes communication slower and harder, causing a delay in decision-making. For

example, a bank with branches in Accra, Kumasi and Tamale may struggle to pass messages quickly between branches. This slows down customer service, leading to an increase in costs.

2. External Diseconomies of Scale

These are the disadvantages that come from outside the firm due to many firms operating in the same area. This increases the average cost of production for firms.

Examples are:

a. Overcrowding and congestion: In an industrial area like Tema, roads become congested. This delays the delivery time of trucks, leading to an increase in fuel costs.

b. Increase in input prices: When many firms operate in the same area, their demand for raw materials increases, causing an increase in prices of raw materials. This increases the cost of operation of each firm. For example, in Dormaa, where there are many poultry farms, the demand for chicken feed always increases. This increases the price of chicken feed, resulting in an increase in the operation costs for all the poultry farmers.

c. Environmental Pollution and fines: When too many firms operate in the same area, they cause environmental pollution. Therefore, District Assemblies may impose a pollution and noise levy on each of the firms. This increases business costs for firms. For instance, in Tarkwa, several mining companies release waste into rivers and land. As pollution worsens, the government brings in new environmental laws and fines, making it more expensive for each company to operate.

Scenario:

A fruit juice company in Koforidua started with just 2 workers. They used fresh local fruits and blended juices in a small kitchen to produce fruit juice, which was sold at schools and bus stations. They were making good profits.

As more people got to know their product orders for the juice started increasing and the owner therefore decided to expand the company. She rented a bigger space, bought larger machines and employed 15 new workers.

However, after the expansion:

1. It became difficult to manage all the workers properly.

2. Some workers had no clear duties, so they spent time doing nothing.

3. The quality of the Juice reduced, and customers began complaining about taste and packaging problems.

4. The cost of buying fruits in large quantities increased because many other juice companies in the area were also buying from the same suppliers.

As a result, the average cost per bottle of juice increased, even though they were producing more. This is an example of diseconomies of scale.

Key Causes of Diseconomies of Scale

Cause Explanation

Managerial Problems

Large firms like Total Energies may face delays in decision-making due to many branches and managers.

Poor Worker

Motivation Workers in shopping malls may feel they are not noticed, and they work with less effort.

High Maintenance

Cost Companies like Aluworks that use heavy machines will spend more on repairs and maintenance.

Communication Breakdown

Large companies with many branches, like GCB Bank, face difficulty in sending information across all branches at the same time.

Increased Regulation

Companies like plastic manufacturers face EPA regulations and compliance costs.

Traffic & Congestion Firms in Accra Central face traffic congestion, which delays deliveries and increases fuel costs.

Activity 3.3 Understanding Diseconomies of Scale

Purpose: The purpose of this activity is to help you explore what happens when businesses grow too large and learn to identify warning signs through case study analysis.

Duration: 50 minutes Group Size: 4-5 learners per group Materials needed: Notebook, Pen, Pencil, Ruler, Manila card (if available) Instructions:

Step 1: Group Formation & Research Preparation (5 minutes)

a. Form groups of 4-5 learners

b. Assign roles: Lead Researcher, Case Study Analyst, Discussion Leader, Presenter, Recorder

Step 2: Research & Definition Phase (15 minutes) Using textbooks, smartphones or available resources:

a. Define diseconomies of scale (5 minutes)

b. Identify and discuss at least three main causes of diseconomies of scale.

e.g., Managerial diseconomies (10 minutes)

Step 3: Case Study Analysis (20 minutes) Read the MegaMart case study and analyse the questions that follow:

MegaMart’s Management Struggles

MegaMart is a large retail chain that expanded rapidly across Ghana. Within five years, it opened over 200 branches and hired thousands of employees. However, profits began to fall despite increasing sales.

Local store managers complained about slow decision-making from the head office.

Employees became demotivated due to a lack of recognition and communication breakdowns. Again, there was a duplication of roles, causing inefficiencies and rising administrative costs. Customer service quality also declined across branches. Inventory management became chaotic with frequent stockouts and overstocking.

Questions

1. What types of diseconomies of scale is MegaMart facing?

2. How could the company restructure to reduce these issues?

3. What lessons can other Ghanaian businesses learn from MegaMart’s experience?

Step 5: Class Discussion and closure (10 minutes) Compare your findings and suggest other practical solutions for MegaMart’s challenges.

Comparison of Economies and Diseconomies of Scales

Feature Economies of Scale Diseconomies of Scale

Meaning A situation where the cost per unit falls as the firm expands.

A situation where the average cost per unit increases as the firm over-expands.

Effect on Average

Cost It reduces the average cost of production.

It increases the average cost of production.

Impact on Profit Profit margins increase due to lower costs.

Profit margins may decrease due to higher operating costs.

Business Size Occurs when a firm expands or becomes larger.

Occurs when a firm becomes too large and difficult to manage.

Causes Specialisation, buying in bulk, better technology, getting cheaper loans and finance.

Poor management, low worker motivation, overcrowding and poor supervision.

Managerial Efficiency

Management is very easy and organised because every worker knows his/her role.

There is confusion and repetition of roles due to unclear roles.

Workforce Productivity

Workers become more skilled and efficient through repetition.

Workers may feel bored and less motivated and underused.

Examples in

Ghana A local bakery in Accra buys flour and butter in bulk, reducing the costs of baking each loaf.

The bakery expands with many branches in Kumasi and Koforidua but faces difficulty with vehicle maintenance and driver delays.

Communication Becomes easier with better systems.

Communication slows down as more branches or departments are added.

Customer Service Often improves due to better facilities and training.

May decline if customer concerns are lost due to delays.

Financial Effect Leads to a decrease in cost, which helps to save money for improvement in product quality Leads to an increase in cost, causing the business to struggle.

Example

• A rice processing plant in Tamale buys tractors, dryers and packaging materials in bulk. It becomes cheaper to process each bag of rice.

• As more rice processing plants are established in Aveyime and Asutuare, more workers are employed. Supervision becomes difficult, decision-making delays and production mistakes may occur; this is known as diseconomy of scale.

Activity 3.4 Economies vs Diseconomies of Scale Analysis Purpose: The purpose of this activity is to help you compare both concepts and develop strategies to help businesses grow efficiently while avoiding common pitfalls.

Duration: 55 minutes Group Size: 4-5 learners per group Materials needed: Notebook, Pen, Pencil, Ruler, Manila card (if available) Instructions

Step 1: Group Formation & Task Division (5 minutes) Form groups of 4-5 learners Assign roles: Chart Designer, Case Analyst, Strategy Developer, Presenter, Timekeeper

Step 2: Comparative Analysis (20 minutes) Create a Venn diagram or comparison table covering:

a. Definitions of economies and diseconomies of scale (5 minutes)

b. Main causes of each concept in ‘a’ above (10 minutes)

c. Effects on average cost - how each impacts business costs (5 minutes)

Step 3: Case Scenario Analysis (20 minutes) Analyse the CocoaDelight Ghana Ltd.

CocoaDelight Ghana Ltd. (Cocoa-based products) Background: CocoaDelight started as a small family-owned cocoa processing business in Ghana. Due to rising demand locally and internationally, the company expanded by buying new machines, hiring more workers and building two new production centres in different regions.

In a few months, the bulk purchase of cocoa beans reduced the raw material costs of the company. Modern machines have also increased productivity significantly. The skilled technicians reduced wastage and errors, leading to access to larger markets through multiple locations.

As the company continued its expansion projects, managers began to complain of longer decision-making chains. Some workers reported that they felt disconnected and demotivated.

Transportation costs rose due to operations spread across regions. Eventually, quality control became inconsistent between the different locations of the same company.

Questions

1. What economies of scale are CocoaDelight benefiting from?

2. What diseconomies of scale are starting to appear?

3. What advice would you give to maintain efficient growth?

Closure: Each group summarises their findings and shares with the entire class.

A firm is said to be in equilibrium when it has no reason to change the amount of goods or services it produces. This is because it is either making the highest profit possible or minimising loss.

In Ghana, this idea applies to all types of businesses, whether a larger company like Nestlé Ghana or a small business like a bread-baking shop in Kumasi. Each of them aims to reach a point where they are making the highest profit while keeping their cost low.

Conditions for Firm Equilibrium

A firm reaches equilibrium when:

Marginal Cost (MC) = Marginal Revenue (MR) MC curve cuts MR from below.

This is the point where the firm earns the highest possible profit at the least cost.

Let us break it down:

If MR > MC, the firm should produce more, because the extra product brings in more revenue than it costs to make.

If MR < MC, the firm should produce less, because producing more would cost more than it earns.

If MR = MC, the firm is at equilibrium and profit is at its highest.

It is important to produce at the equilibrium output because at the optimal output level, when a firm is making positive profit, it achieves the highest by producing at the equilibrium output. On the other hand, if a firm is making loses, it makes the least when it produces at the equilibrium output level.

Example:

Nana K. Ofori Limited, a popular dealer and distributor of building and construction materials in Ghana, is in equilibrium when it supplies exactly the number of building materials at the point where the marginal cost is equal to the marginal revenue.

If Nana K. Ofori limited supplies are less than the equilibrium output, its profit margin will be low.

If it supplies more than equilibrium output, the marginal cost is higher than the revenue, leading to losses.

But at MR = MC, the firm is at its best output level. Therefore, there is no need to increase or reduce production.

Short-Run Equilibrium Condition

In the short run, a firm can still operate even if it is making losses, as long as it covers its variable costs such as electricity, raw materials and wages.

For example, the tomato processing factory in Techiman may continue production during a season when sales are low, as long as it can pay workers and buy tomatoes.

The hope is that in the future, sales will pick up again.

The following graph shows how the equilibrium condition of a firm operates in the short run, under perfect competition. Equilibrium is shown at the point where the revenue curve cuts the cost curve, MR = MC.

Short-run equilibrium of the firm Long-run equilibrium condition In the long run, all the costs incurred in a business can change, including rent, salaries, equipment and raw materials. This means that, in the long run, the firm can expand or reduce its size, change its production methods or even leave the market.

For a firm to stay in business in the long run, the average revenue must be greater than or equal to the average total cost (AR ≥ ATC). This is enough to cover all its costs and allow production to continue.

If AR is less than ATC (AR < ATC), the firm is making losses. It must therefore shut down and exit the market. This is shown in the graph below. Note that AC is interchangeable with ATC

Activity 3.5 Understanding Firm Equilibrium

Purpose: The purpose of this activity is to help you understand firm equilibrium and practice explaining economic reasoning through talk for learning approaches.

Duration: 50 minutes Instructions

Step 1: Individual Definition (5 minutes)

a. Write down a definition of «firm equilibrium» in your own words

b. Think about the situation when a firm has found the best production level

Step 2: Partner Sharing (5 minutes)

a. Turn to a partner and explain your definition out loud

b. Listen carefully to your partner’s definition

Step 3: Think-Pair-Explain Scenario (20 minutes) Scenario: A firm is producing 200 units of a commodity at a cost of GH₵4 per unit and selling them at GH₵6 per unit.

a. Given the information below

i. Total Cost (TC) = 200 units × GH₵4 = GH₵800

ii. Total Revenue (TR) = 200 units × GH₵6 = GH₵1,200

iii. Marginal Cost (MC) = Additional cost of producing one more unit = GH₵4

iv. Marginal Revenue (MR) = Additional revenue from selling one more unit = GH₵6

b. Individual Think Time (5 minutes) Based on the information above, consider these questions silently:

i. Should the firm increase or reduce output? Why?

ii. Is the firm in equilibrium at 200 units?

iii. What information do you need to confirm equilibrium?

iv. How do marginal cost and marginal revenue relate here?

c. Pair Discussion (10 minutes)

i. Partner A explains their reasoning for 2 minutes whilst Partner B listens

ii. Partner B explains their reasoning for 2 minutes whilst Partner A listens

iii. Discuss and compare your answers (6 minutes)

d. Class Sharing and closure (5 minutes)

i. Summarise what your partner said before sharing your view with the class

ii. Focus on explaining the relationship between MC and MR in determining equilibrium

Note for the learner: A firm reaches equilibrium when Marginal Cost (MC) equals Marginal Revenue (MR). If MR > MC, the firm should increase production.

If MC > MR, the firm should reduce production.

An industry is in equilibrium when the forces of supply and demand are balanced, resulting in a stable market price and quantity that show no tendency to change. At this point, the market is stable, and all firms are earning normal profit.

Conditions for Industry Equilibrium

An industry reaches equilibrium when:

1. All firms are in equilibrium, meaning Marginal Cost (MC) = Marginal Revenue (MR)

2. Firms make normal profit — no abnormal profits or losses

3. Market demand equals market supply, so the price stays stable Industry Equilibrium in Different Market Structures Perfect Competition A perfectly competitive industry has many firms selling identical products, with no single firm controlling the price.

Conditions in long-run equilibrium;

1. Firms are free to enter or leave the market

2. All firms earn normal profit (zero economic profit)

3. Price = Marginal Cost (P = MC)

Example

At the Tamale Central Market, many sellers offer the same type of groundnuts at similar prices. When profits increase due to high demand during festival periods, more sellers enter. Later, as profits fall, some sellers switch to other goods like beans or millet. Prices stabilise and the remaining sellers earn normal profit.

Short-Run Industry Equilibrium

In the short run, firms may earn supernormal profits or make losses because;

1. Barriers to entry prevent new firms from entering immediately.

2. Some costs (like rent or equipment) are fixed in the short run.

Example:

When the price of maize rises due to inadequate rainfall, maize farmers in Ejura earn supernormal profits. Because it takes time to clear land, buy seeds and grow the crops, not every farmer can quickly switch to maize farming. Therefore, in the short run, only existing maize farmers enjoy the high profits, and new farmers cannot enter the market immediately.

Long-Run Industry Equilibrium

In the long run, the industry is in equilibrium when;

1. All firms in that industry earn normal profit

2. There is no entry and exit of firms

3. Industry supply is equal to industry demand

Example

Over the years, many young people opened barbering salons because it looked profitable. They made supernormal profits at the beginning. As more people joined the business, competition increased. Now, the number of barbering shops is enough to meet customer demand. Most barbers earn normal profit. This shows that the barbering industry is in long-run equilibrium. The point on the graph below where the supply curve meets the demand curve represents normal profits.

Monopolistic Competition

In this case, an industry has many firms selling slightly different products. These products are differentiated through branding and quality.

In the long run, equilibrium leads to the following;

1. Firms in the industry earn normal profits

2. They operate with excess capacity (not at full efficiency)

Example

In Koforidua, many bakeries produce bread with different tastes and packaging. Each tries to attract customers. But as more bakeries open, competition increases, prices become stable and all the firms earn normal profits over time. In the graph below, in the long-run equilibrium for a monopolistically competitive firm, the point where the firm’s demand curve (AR) is tangent to its Average Total Cost (ATC) curve represents normal profit.

Oligopoly An oligopoly is a market structure where a few large firms dominate the industry.

These firms are interdependent, meaning each one considers the actions of the others when making decisions. Oligopolies have several key characteristics: there are few dominant firms, high barriers to entry that prevent new competitors from joining easily, and price rigidity, where prices do not change frequently even if costs or demand change. Because firms watch each other closely, this interdependence often leads to behaviours like price leadership, where one firm sets the price and others follow, and collusion, where firms secretly agree to fix prices or limit production. Understanding these characteristics helps explain why oligopoly firms behave differently from those in more competitive markets.

Example

Firms like MTN, Vodafone and Telecel dominate Ghana’s mobile network industry.

While they compete through data bundles and mobile money offers, one firm (usually MTN) often sets pricing trends and the others follow. In the graph below the point where MC = MR defines the profit-maximising output level for each firm. The demand curve shows that firms in the industry must stick with agreed pricing or quantity, or their marginal revenue might fall.

Monopoly A monopoly is a market with only one firm with barriers to entry.

Equilibrium occurs when;

1. The industry maximises profit where MR = MC

2. New firms cannot enter due to high barriers

Example

GWCL is the sole provider of pipe-borne water in most parts of the country. Because the operational cost is so high, no other firm competes directly. The company is regulated and sets prices to cover operational costs while serving the public. In the graph below, the regulated price would be below the monopolist’s profit-maximising price, possibly closer to average cost (AC). This shifts the equilibrium to the right, increasing output and reducing price. In this situation, the single firm in the water industry may still earn normal profit, but supernormal profit is constrained.

How Industry Equilibrium Adjusts Over Time

If an industry is not in equilibrium:

1. Supernormal profits attract new firms into the market, thereby increasing supply and reducing prices until only normal profits remain.

2. Firms exit the industry due to losses, reducing supply and increasing prices until normal profit is earned.

Example

Poultry farming became very profitable in Dormaa Ahenkro, attracting many new farmers. Over time excess supply of chickens caused prices of eggs and chicken to drop. As profits reduced, some farmers left the business. Supply was reduced to match demand, where remaining poultry farmers earned normal profit.

Activity 3.6 Understanding Industry Equilibrium

Purpose: The purpose of this activity is to help you understand how entire industries reach equilibrium and practice explaining market dynamics through discussion.

Duration: 45 minutes Instructions

Step 1: Individual Writing (5 minutes)

a. Write down what you think an industry is. (2 minutes)

b. Write what it means for an industry to be in «equilibrium»(3 minutes)

Step 2: Think-Pair-Explain Scenario (15 minutes) Scenario: In the bottled water industry in Ghana, new firms entered the market because existing companies were making high profits. However, over time, prices dropped and some firms had to exit the market.

a. Individual Think Time (5 minutes) Think about these questions silently:

i. What stage of industry equilibrium does this describe?

ii. What will likely happen to supply, demand and prices next?

b. Pair Discussion (10 minutes)

i. Partner A explains their thinking for 3 minutes whilst Partner B listens

ii. Partner B explains their thinking for 3 minutes whilst Partner A listens

iii. Discuss and agree on your answers, write them in your notebook (5 minutes)

c. Class Sharing (10 minutes) Share your pair›s conclusions with the class when called upon.

Note for the learner: Industries move towards equilibrium as firms enter when profits are high and exit when profits are low, until normal profits are earned.

Firms operate with different goals depending on their size, type of ownership and the market they operate in. In Ghana, firms exist across various sectors like agriculture, manufacturing and services. Their goals are shaped by factors such as economic conditions, government policies, available resources and consumer demand.

Below are the main objectives that firms in Ghana aim to achieve:

1. To maximise profit Most firms aim to make the highest possible profit. The higher the profits they make, the more the firm expands and the higher the reward to owners or investors. For

example, FanMilk Ghana Ltd may increase production of yoghurt during hot seasons to meet high demand and maximise sales revenue.

2. To promote growth and expansion Firms aim to increase their size, sales, enter new markets and produce new products.

Growth may be internal (by producing more) or external (by partnering or merging with others). For example, Kasapreko Company Limited, a beverage manufacturer, may open a new bottling plant in the Ashanti Region and Western Region to increase output. A local bakery in Ho may buy more ovens to produce more bread and serve more customers.

3. To ensure market dominance Some firms try to become the most popular or biggest in their industry by attracting more customers than competitors. For example, MTN Ghana uses aggressive marketing and wide network coverage to remain the leading telecom company. A cement company like Dangote may reduce prices and advertise heavily to become the top brand in Ghana’s construction market.

4. To increase customer satisfaction Firms aim to meet customers’ needs by offering high-quality goods and services, which builds customer loyalty and demand. Satisfied consumers may advertise the product or service by recommending to others. For examples, CalBank uses mobile apps to make banking easier and faster. Also, KFC Ghana offers quick service and consistent food quality to satisfy customers.

5. Social and Community Responsibility

Some firms aim to contribute to society through improvement in infrastructure in areas where they are located even if it does not increase profit in the short term. This is called Corporate Social Responsibility (CSR). For examples, Newmont Ghana, a mining company in Akyem offered scholarship packages for about 10,000 students in Akyem and sponsored TVET and apprenticeship programmes.

6. To create employment Firms help reduce unemployment by providing jobs, especially in areas where they are located. This helps to reduce unemployment in the country. For examples, a cassava processing factory under 1D1F in Addo-Nkwanta in the Krachi East District employs most people in the area. Similarly, Blue Skies in Nsawam employs a lot of people to process fruits for export.

7. Survival Firms aim to continue operation even in tough economic times, like high inflation or cedi depreciation and pandemics. They may not aim for high profit but could attempt to cover costs, reduce losses and avoid shutdown. For example, an importer of car spare parts in Abossey Okai may reduce the number of items imported and cut costs to survive when the dollar rate rises sharply. Again, a private school in Gomoa Potsin may lower school fees or offer flexible payment plans during economic hardship, just to retain students and avoid collapse.

8. Innovation and Efficiency

In order to be competitive, some firms aim to improve their production processes, reduce costs and offer unique products. For example, Nestlé Ghana upgraded its Tema factory with automated machines to speed up production of Milo and Cerelac while cutting down costs.

Step 4: Group Presentations (5 minutes) Each group shares one key insight from their discussions (1 minute per group)

Step 5: Class Synthesis (5 minutes) Summarise the main objectives of a firm and the factors that influence them Discussion Prompts

i. Think about local businesses: What drives a small chop bar vs. a large company like MTN?

ii. How might a firm›s goals change during economic difficulties?

iii. What happens when firms face new competitors?

Price discrimination happens when a seller charges different prices for the same product or service to different customers. The difference in price is not due to production costs but because of factors like a buyer’s income level, age, location or willingness to pay.

It usually happens in imperfect markets, especially in a monopoly or monopolistic competition, where the firm has some control over prices.

Types of Price Discrimination

₁. First-Degree Price Discrimination (Perfect Price Discrimination) Under this, the seller charges each customer the highest price they are willing to pay.

This is not common because it requires knowing each person’s exact willingness to pay. For example, a private basic school in Accra may charge different school fees to different parents based on their ability to pay. A wealthy parent might be charged GHS 3,000 per term while a low-income parent may be charged GHS 2,000 for the same tuition. This is not because of cost differences, but because the school knows each parent›s willingness or ability to pay.

2. Second-Degree Price Discrimination (Quantity-Based)

The price the buyer pays depends on the amount of goods bought or the type of service chosen. Bulk buyers usually get lower unit prices. For example, ECG allows consumers who use less than 50 kWh per month to enjoy a lower rate per unit (lifeline users).

Those who use more electricity pay higher rates per additional unit. This is to ensure there is no wastage of electricity.

3. Third-Degree Price Discrimination (Group-Based)

Different groups of customers are charged different prices based on age, location or occupation. For example, MTN Ghana sometimes offers location-based discounts through its “Zone bundles.” Customers in urban areas like Accra may get data at a different price, while those in rural areas may enjoy cheaper rates or special promos.

Here, prices vary based on the geographical location.

Conditions for Price Discrimination

For a firm to charge different prices, the following must be present:

1. There must be some level of market power: The firm must have control over pricing (not in perfect competition).

2. The Market must be separated: The firm must be able to divide customers into different market groups with different price elasticities of demand. For example, Hospitals can separate NHIS cardholders from private patients.

3. There should be no possibility for resale: Consumers must not be able to buy at a low price and sell to others.

4. There must be different price elasticities: Firms charge more to people with inelastic demand (less sensitive to price) and less to those with elastic demand (very price-sensitive).

Reasons for Price Discrimination

1. To make more profit by capturing more consumer surplus.

2. To attract low-income groups who cannot afford the full price.

3. To clear excess supply by offering discounts.

4. To reward loyalty or promote social groups (e.g. discounts for students).

Advantages of Price Discrimination

₁. It increases revenue for producers, which may help increase production and improve service. For example, ECG uses extra revenue to maintain power lines.

2. To help low- income earners have access to goods.

3. It helps in efficient use of resources during low-demand periods. For example, cheaper night-time electricity promotes off-peak use.

4. It helps to ensure that profits from more profitable areas are used to support the delivery of services in rural or low-income areas. For example, Telecom firms use urban profits to support rural services.

Disadvantages of Price Discrimination

1. It can be seen as unfair, especially if rich people get lower prices.

2. It can lower the benefits consumers receive from a purchase and widen the gap between high-income and low-income groups.

3. Difficult to apply without enough market information.

4. May reduce competition in monopoly markets.

Practical examples

a. Movie cinemas charging lower ticket prices for students and children compared to adults. For example, Silverbird Cinemas may offer discounted tickets to students who show a valid student ID.

b. Internet cafés offering cheaper hourly rates in the morning than in the evening.

c. MTN or Vodafone offering cheaper call/data rates in rural areas than in cities.

d. Private schools charging different fees based on parent’s income or number of children enrolled.
