Q

What is divorce of ownership from control ?

A

As firms grow, they may sell shares to finance their expansion.
Shareholders do not run the company, managers do.
So, there is a divorce of ownership and control.

Q

What is the principle agent problem ?

A

Due to divorce of ownership from control
The interests of the manager may not be in the interest of the shareholder but shareholders are not able to very easily monitor the behaviour of managers.
The manager may benefit more from revenue maximisation than profit maximisation, and so the manager may not act in the shareholders best interest.

Q

How can shareholders regain control from managers/realign their values ?

A

This can be done by holding them accountable for the firms performance, adding pressure for them to perform in the shareholder’s interest.
Managers could also have their pay linked to the share price over a number of years, for example.
This realigns the goals of managers and shareholders

Q

What are reasons owner’s objectives keep a firm from growing ?

A

Some business owners or founders may decide that they don’t want to grow.

Growing and hiring more employees increases the amount of legal, accounting and bureaucratic burden for a firm.

Owners may be risk-averse and just want to run a ‘lifestyle business’ that can fund their own desired income. Satisficing
For example, a software developer setting up a company to sell his services may not want to hire other developers and grow, preferring to focus on funding his own income.

Q

How does access to capital stops a firm from growing ?

A

If a business cannot access capital, then it is unable to spend anything other than profits to grow. When companies are small, often they don’t make huge profits because they have to cover both their fixed and variable costs, but don’t have many customers to spread their fixed costs over.

After the 2008 financial crisis, many businesses reported that banks would not lend to them.
CB Insights research finds that 29% of failed startups failed because they ran out of cash.
If a company cannot issue equity or borrow from banks, then it has bad access to capital.

Q

How can the type of firm stop a firm from growing ?

A

Not for profit firms may only hope to improve one social issue in one area - e.g. homelessness in Leeds. They may have no incentive to grow, even if they could.

Firms or departments in the public sector may have no incentive to grow. The UK Department for Education has no funds allocated and no desire to expand internationally.

Q

How can the size of market stop a firm from growing ?

A

Sometimes the size of a company’s market is not large enough for a firm to grow anymore. If a company sells Chilli-flavoured ice cream, there may not be enough demand outside of very niche ice cream shops. This can limit growth because the firm is in a ‘niche market’.

Research by CB Insights found that 42% of startups failed because the market didn’t need their product and 9% failed because of a failed geographic expansion.

Q

How is opening a new store organic growth ?

A

Opening a new store is a common way for a company to expand as it allows them to be closer to customers in another location. It can be low risk if the business model is already proven to work.

Aldi and Byron burger shop are examples of this. They opened up lots of stores in different towns, all using a similar business model and operations.
However, internal expansion can need a lot of investment and can be costly.

Q

How is launching new products organic growth ?

A

Launching new products can help businesses to expand their customer base as well as potentially selling more products to people who are already customers.
For example, Virgin Records then launched the Virgin Trains, Virgin Atlantic (airline) and Virgin Active (gyms) businesses.
This can be risky due to the large investment required and the fact the business owner may not be as knowledgeable in other product markets

Q

How is increasing production capacity an example of organic growth ?

A

Investing in new capital and technology can allow a business to produce more goods.
If for example, a firm’s products are consistently selling out and they are unable to produce more, then the production capacity is restricting their expansion.

Q

What is conglomerate integration?

A

Conglomerate integration is a merger/acquisition between two completely unrelated businesses.

Apple purchasing Tesco would seem to be an example of this.

However, Amazon buying Whole Foods may not be an example of conglomerate integration, rather backward vertical integration by Amazon, as Amazon already distributed some food to consumers.

Q

How is reduction of competition an advantage of external expansion ?

A

A firm can merge with or take over a competitor.
This can reduce the amount of competition that a business faces. It can also increase market share and let the company benefit from economies of scale.

For example, in 2004, the Morrisons supermarket company took over Safeway supermarkets. This increased the number of Morrisons stores to over 500 from 120. Morrisons’ market share rose from 6.4% to almost 15%. This was another example of horizontal integration

Q

How is rapid expansion a benefit of external expansion ?

A

The key benefit of external expansion is the speed with which firms can expand.

For example, in 2014 Facebook bought WhatsApp for $19 billion. This is a large amount of money but it instantly gave Facebook 700 million customers. This was an example of vertical integration.

Q

How is diversifying (spreading risk) an advantage of external expansion ?

A

A firm can merge or take over a firm in a different industry. This makes the company less reliant on its existing products/services and can diversify (or spread) a company’s risk.

For example, in 2011, Microsoft (an operating system company) bought Skype (a video calling company). This was either a conglomerate integration or a horizontal integration.

Q

Why may employees become demotivated after integration ?

A

Employees may be demotivated due to different management style and culture.

When Virgin Active took over Esporta Health Clubs, personal trainers and other gym staff became frustrated with new working practices. Staff turnover increased significantly after this takeover.
Daimler (the company that makes Mercedes cars) merged with Chrysler in the late 1990s. The company had very different cultures and in 2007, Chrysler was sold by Daimler to an investment company.

Q

Why may tension and job loss occur when integration occurs ?

A

Mergers and takeovers often lead to attempts to cut costs.
Attempts to cut costs often lead many people to lose their jobs and this can create tension in a workforce.
This happened when Morrisons took over Safeways supermarkets in the UK in 2004.

Q

How does complication happen when integration occurs ?

A

The costs of a merger/takeover can outweigh the benefits.

For example, the two businesses’ operations will have to merge.
If 2 businesses employ 5,000 people in 30 countries, combining this operations would not be easy or straightforward. This can lead to diseconomies of scale.

Q

Why is underperforming business unit a reason for a demerger ?

A

If only one part of the business area is underperforming then it may make sense to demerge that part of the business so that management can focus more on the more successful business areas or units.
Equity markets may increase the ‘multiple’ that investors will pay for a business if it only contains 1 successful business instead of 1 successful business and 3 underperforming businesses. Therefore a demerger could create shareholder value.

Q

How is antitrust a reason for a demerger ?

A

Like how governments block some takeovers, a firm may demerge because of government intervention.
If a government views a monopoly market structure as a market failure, then the government may force the firm to be broken up.

Q

What is the impact of a demerger on business ?

A

A business is likely to have a better focus after a demerger.
The total equity value of the business units may rise after a de-merger. If the businesses were unrelated, then a ‘conglomerate discount’ may vanish.
If a business was suffering from diseconomies of scale, then a demerger may increase efficiency and lower average cost. However, if the business was operating at the minimum efficient scale, then a lower output may increase average cost.
Selling a loss-making business is difficult. People are more likely to want to buy a successful business. ‘Realising a loss’ on a past acquisition and accepting it was a bad choice may harm management’s power in the business.

Q

What is the impact of a demerger on workers ?

A

Some workers may be forced to work for a new legal entity or employer. There may be cultural clashes or a fall in morale.
If the demerger happens to fund investment, then some of this investment may be in machinery or automation tools that reduce the need for labour.
Operating in a smaller firm may be good for workers. Dunbar’s number finds that people can operate in groups of up to 150 whilst maintaining strong social relations with all of the other members of the group.

Q

What is the impact of a demerger on customers ?

A

If demerging stops a firm suffering from diseconomies of scale, efficiency could rise, costs could fall and prices could also fall, increasing the level of consumer surplus.
But if the firm loses economies of scale, costs could rise and prices could rise. This is likely to reduce consumer surplus and consumer welfare.
But having more firms in an industry may increase choice and competition, leading to higher quality products/services and lower prices.

Q

What is the point of profit maximisation ?

A

Firms maximise profit when the marginal revenue (MR) is equal to the marginal cost (MC).

Any extra units produced from here will have a negative impact on profit.
This is because of diminishing returns. So marginal cost will be higher than marginal revenue past this point of MC=MR.

Q

A

To make profit, firms may have to achieve a number of other objectives first.
E.g to gain long run profit, it might be more important to gain revenue and market share in the short term so that economies of scale and price-setting power can be first achieved, even if profit must be sacrificed.
Amazon has made very little profit in the last 10 years and seems to have aimed to maximise market share in the short run. A challenge for Amazon would be how to increase their profit margin (how much is charged to the customer over and above costs) without making itself vulnerable to competition.

Q

What is market share as a firms objective ?

A

Firms may try to maximise market share (without making a loss), also known as sales maximisation.
To do this, a firm would produce where average revenue is equal to average cost.
A company such as Tesco may focus on this; it would allow them to achieve economies of scale and greater price-setting power in the long-run.
This could be beneficial to managers due to the prestige, and the perks they may receive from managing a large firm.

Q

What is satisficing as a firms objective ?

A

Bounded rationality can limit our ability to make choices that lead to profit maximisation.
As a result, profit maximisation is not always possible.
Some firms will satisfice instead. The theory of satisficing was proposed by Herbert Simon.
This involves reaching a minimum requirement in a number of areas.
E.g setting a minimum goal for profit, sales and revenue

49
Q

What is not for profits as a firms objective ?

A

These are firms that don’t aim to maximise supernormal profits.
But rather, to operate in ways that are beneficial to society.
E.g a student union.

50
Q

What is revenue maximisation as a firms objective ?

A

Firms may try to maximise revenue.
To do this, a firm must produce where marginal revenue is equal to zero.
Revenue maximisation increases the size of the firm, this could be beneficial to managers due to the prestige, and the perks they may receive from managing a large firm.
Amazon seems to be a company that has aimed to maximise revenue, at least in the short run.

51
Q

With reference to satisficing, explain why it may not be possible for a firm to profit maximise.

A

Bounded rationality can limit our ability to make choices that lead to profit maximisation.
As a result, profit maximisation is not always possible.
Some firms will satisfice instead. This involves reaching a minimum requirement in a number of areas.
E.g setting a minimum goal for profit, sales and revenue.

52
Q

What are the types of revenue ?

A

Total revenue
Average revenue
Marginal revenue

53
Q

What is total revenue ?

A

Total revenue is the income brought into the firm from selling its products.
Total revenue = price × quantity.

54
Q

What is average revenue ?

A

Average revenue = total revenue (price × quantity) ÷ quantity.
So, average revenue = price.
So, if price is equal to average revenue, you could simply rewrite the average revenue curve as the demand curve.

55
Q

What is marginal revenue ?

A

This is the additional revenue gained from selling the last output unit.
If marginal revenue is positive, total revenue could be increased from expanding output.
So, total revenue is maximised when marginal revenue is equal to zero.

56
Q

What’s the relationship between marginal and average revenue ?

A

The midpoint of the average revenue curve is where total revenue is maximised.
The marginal revenue curve has twice the steepness of the average revenue curve.

57
Q

Define marginal revenue and explain its relationship with total revenue.

A

Marginal revenue is the additional revenue gained from selling the last output unit.
If marginal revenue is positive, total revenue could be increased from expanding output. So, total revenue is maximised when marginal revenue is equal to zero.

58
Q

What are price makers ?

A

Price makers have partial control over the price at which their goods are sold.

Firms can maximise total revenue by operating at the point where the price elasticity of demand is equal to -1.

59
Q

Hate re price takers ?

A

If selling price cannot be controlled (and so the firm is a price taker), there is perfectly elastic demand.
Increasing the price causes the quantity to fall to zero.
Here, marginal revenue is equal to average revenue.

60
Q

If a product is price elastic of demand what will decreasing price do to revenue ?

A

Decreasing price = increases total revenue.

61
Q

If a product is price elastic of demand what will increasing price do to revenue ?

A

Increasing price = decreases total revenue

62
Q

If a product is price inelastic of demand what will decreasing price do to revenue ?

A

Decreasing price = decreases total revenue.

63
Q

If a product is price inelastic of demand what will increasing price do to revenue ?

A

Increasing price = increases total revenue

64
Q

How does price elasticity of demand (PED) change along the demand curve?

A

Straight-line demand curve

At zero demand or high price - minus infinity.
At midpoint - elasticity is minus one.
At zero price or high quantity - elasticity is zero.
PED of +/- one = maximised total revenue.
The closer a product’s price is to the midpoint, the higher the revenue.

65
Q

What are marginal costs ?

A

Marginal cost is the change in total cost divided by the change in output for each possible level of output.
These are usually rising.
Only variable costs affect marginal costs.

66
Q

What does average cost measure ?

A

Average cost measures cost per produced unit. Average cost is total cost over total output

67
Q

What is average total cost ?

A

the total cost divided by total output at each level of output

68
Q

What is average variable cost ?

A

variable cost divided by total output at each level of output

69
Q

What are fixed costs ?

A

Fixed costs do not change regardless of the level of production (or output). Fixed costs cannot be changed in the short run.
E.g machinery.

70
Q

How are variable costs generated ?

A

Variable costs are generated in the act of producing. The more you produce, the greater the variable cost.
These can be changed in the short run.
E.g the amount of material bought by Zara to make clothes

71
Q

What do marginal costs effect ?

A

When marginal cost changes, it affects average cost

72
Q

When marginal cost < average cost, what does this mean for a average cost ?

A

When marginal cost < average cost = average cost is decreasing

73
Q

When marginal cost > average cost, what does this mean for average cost ?

A

When marginal cost > average cost = average cost is increasing

74
Q

Where is average cost at its lowest ?

A

where average cost is equal to marginal cost.

75
Q

What is total cost ?

A

the sum of the fixed and variable costs

76
Q

What shape is a marginal cost curve ?

A

A tick/U-shaped

77
Q

Why is a marginal cost curve a tick/U-shaped ?

A

Initially as output increases, marginal cost falls.
But diminishing returns start to take place at a certain level, and so marginal cost will start to rise

78
Q

What shape is the average cost curve ?

A

U-shaped

79
Q

Why is the average cost U-shaped ?

A

When the marginal cost is below the average cost, the average cost is falling.
When marginal cost is above average cost, the average cost will rise.

80
Q

Why is average total cost U-shaped ?

A

This curve declines at first, as marginal cost is falling.
This is because fixed costs stay the same, over an increasing level of output.
As marginal cost starts to rise, the average total cost curve will follow

81
Q

What happens to the average cost if the marginal cost is above the average cost?

A

Average costs rise

82
Q

What is diminishing marginal returns ?

A

the concept that the more of something you add, the lower the impact of each additional unit, assuming all else is fixed

83
Q

What is diminishing marginal product ?

A

When firms choose to create goods or services they will select the most productive factors of production to use.

As they produce more goods, the firm will have to use less and less productive factors of production (because they have already used the best).

84
Q

What is an example of diminishing marginal productivity?

A

If you were a farmer, you would choose the most fertile field and effective workers available to you when you start producing.
If you want to produce any more you have to start using less fertile fields and less effective workers.
As a result, each extra field used and worker employed will be able to produce less than the ones before.

85
Q

How do the SRAC curve and LRAC curves link together?

A

The LRAC is the ‘envelope curve’. We usually draw the LRAC as smooth, but it is created by joining all the minimum points on lots of SRAC curves.

Each SRAC curve shapes is U-shaped. Assuming capital is fixed, diminishing marginal returns set in. When they become zero, the SRAC is at its lowest point. After that the marginal return is negative.

86
Q

What does economies of scale refer to ?

A

as the quantity of output goes up, the cost per unit goes down

87
Q

What are internal economies of scale ?

A

Internal economies of scale is the long run process that sees firms learn and adapt, reducing average costs as output increases.

E.g using a new management system that increases efficiency may bring internal economies of scale.

88
Q

What are external economies of scale ?

A

External EoS is when the change that brings about economies of scale happens outside of the firm.

E.g If a new road opens and this allows Ocado to deliver products more quickly and cheaply, this is a case of external economies of scale.

89
Q

How do monopolies occur because of economies of scale ?

A

If having high output reduces a firm’s average costs, then they can sell their products at lower prices than competitors who have lower output.
This can eventually lead to the firm having a monopoly over the market if it’s able to force its competitors out of the market.

Producing aeroplanes is expensive and there are very high fixed (and R&D) costs. The average cost of a plane falls with a higher output. Airbus and Boeing produce most of the planes in the world.

90
Q

What are the types of economies of scale ?

A

Managerial economies of scale
Purchasing economies of scale
Specialisation and division of labour
Technical economies of scale
Marketing economies of scale
Financial economies of scale
Risk-bearing economies of scale

91
Q

What are managerial economies of scale ?

A

Large firms can afford to invest in management technology and employ dedicated managers.
The managers and their systems can improve the productivity of the whole production process by overseeing it effectively.
Project management tools like JIRA and Trello can help businesses to be more efficient.

92
Q

What are purchasing economies of scale ?

A

Larger firms have more power in a market place than small firms. As firms grow they can use this power to reduce the cost of purchasing inputs from their suppliers.
Suppliers are willing to negotiate discounts on their goods and services to increase the quantities that they sell.
As a result, larger firms can buy more at a lower price per good, reducing their costs. This is often known as bulk buying and is a form of price discrimination.
A prominent example of this is in supermarkets who buy a lot of their goods from small suppliers and can force them to take lower and lower prices due to their relative size.

93
Q

What is specialisation and division of labour as economies of scale ?

A

As firms grow, they can designate particular tasks to individuals or groups of workers.
With these workers now only doing one or a small number of jobs it becomes cost effective to give them specific training and equipment which makes them more efficient.
Specialized workers are more productive which reduces average costs.

94
Q

What are technical economies of scale ?

A

Larger firms can afford to invest in specialist technologies (or capital) which reduce the cost of production.
They can do this by spreading the initial cost of buying this technology across the large number of goods and services they sell.
A manufacturing firm can invest in specialist machines to produce their goods more efficiently as long as they produce enough for the lower cost of production to offset the upfront cost of the machines.

95
Q

What is marketing economies of scale ?

A

Mass market advertising on TV and sponsoring large events or places (like Arsenal FC’s Emirates football stadium) has a very large cost. Large businesses can spread this cost over a lot of output, whereas the local corner shop would not even be able to access this type of marketing.

96
Q

What are financial economies of scale ?

A

Larger firms are viewed by financial institutions (like banks) as less risky (less likely to go bankrupt) relative to smaller firms.
Banks are therefore willing to lend money at a cheaper rate as they can be more certain that the money will be repaid.

97
Q

What are risk-bearing economies of scale ?

A

Large firms are considered less of a risk because they tend to be in more markets. As a result the firm overall is less exposed to changes in individual markets.
Firms can be in more markets by diversifying the range of goods and services they produce or by selling to different geographical areas.
The independent shop owner selling a small number of goods is more reliant on its market than the international conglomerate who could survive having to stop selling in a particular country or stop selling a particular good.

98
Q

Hat are diseconomies of scale ?

A

the situation when output rises but this causes average cost to rise too

99
Q

What are internal diseconomies of scale ?

A

Internal diseconomies of scale occur when firms growth begins to cause LRAC to increase (decreasing returns to scale).
As companies grow, they develop tiers of management.
These tiers of management can increase the social distinction between employees.
Communication can worsen, which can reduce overall efficiency.
Managers can find it increasingly difficult to oversee and coordinate actions.

100
Q

What are external diseconomies of scale ?

A

External diseconomies of scale is when the change that brings this about happens outside of the firm.
Increased market performance means raw materials may go up in price.
This will increase average cost for all firms in the industry.

101
Q

How can the LRAC curve show economies of scale and diseconomies of scale ?

A

The long-run average cost curve is U-shaped.
As the curve is decreasing, there are increasing returns to scale as there are increasing economies of scale.
When the curve is flat, there are constant returns to scale.
When the curve is increasing, there are decreasing returns to scale. The upward slope of the curve shows diseconomies of scale.

102
Q

What is the Minimum efficient scale (MES) ?

A

The MES is the lowest output at which average cost is minimised in the long run.
All possible economies of scale have been achieved.
If the fixed costs of an industry are high, the MES will be large.
E.g Building aeroplanes or the National Grid.

103
Q

What is the term meaning the lowest output at which average cost is minimised in the long run?

A

Minimum efficient scale

104
Q

What is profit ?

A

Profit = total revenue - total costs

105
Q

What is normal profit ?

A

When total revenue is equal to total cost, a firm is said to be generating normal profit.
In the long run, normal profit is the minimum a firm can be making to be sustainable.
In a perfectly competitive industry, firms can only make normal profit.

106
Q

What is supernormal profit ?

A

When total revenue exceeds total costs, a firm is said to be generating supernormal profits.
The existence of supernormal profits signals to firms that they should enter the market.
Their ability to do this depends on the barriers to entry and level of contestability.

107
Q

Why are normal profits made in the short run ?

A

In the long run, a firm must make at least normal profits.
But in the short run, at least one factor of production is fixed.
If the firm makes enough revenue to cover its variable costs, and begin to pay off its fixed costs, operations can continue.
The shut down point is the revenue where a firm just covers its variable costs. Below this point the firm will cease production immediately.

108
Q

A firm may continue to function in the short-run, but not in the long-run when price is what?

A

When price is more then variable costs but less than average costs

109
Q

How can profits be signals to potential entrants that they should enter the market ?

A

The existence of supernormal profits in an industry signals to potential entrants that they should enter the market.
Supernormal profits will be competed away if new firms enter.
This logic relies on a number of assumptions about the contestability of markets.

110
Q

When is profit maximised ?

A

When marginal cost is equal to marginal revenue, a firm is profit maximising.

If marginal cost is less than marginal revenue, the firm could increase total revenue by expanding production.

If marginal cost is greater than marginal revenue, the firm could increase revenue by reducing output.

111
Q

Explain the difference between normal and supernormal profits.

A

Normal profit is when total revenue is equal to total cost. In the long run, normal profit is the minimum a firm can be making to be sustainable.

Supernormal profit is when total revenue exceeds total costs. The existence of supernormal profits signals to firms that they should enter the market.

112
Q

What is the assumption which implies that firms will only be able to make supernormal profit in the short run?

A

Contestability of the market

113
Q

What are characteristics of price takers ?

A

To maximise profit they produce where MC=MR.
Only normal profits can be made in the long run.

114
Q

What are the characteristics of price makers ?

A

To maximise profit, again they produce where MC=MR, but supernormal profits can now be made.

115
Q

Why are firms hard to shut down in the short run, and at what point do they shut down ?

A

In the short run the firm is unable to get out of contracts or sell its assets so will continue producing with prices below the minimum average total cost as long as the price covers the average variable cost of production so it can start to pay off some of its fixed costs.

If the situation persists then the firm will look to sell off its assets and get out of contracts (e.g. rent agreements)
If in the short run the market price doesn’t cover the variable costs then the firm will cease production immediately as continuing production will only increase its debt

116
Q

Why would firms shut down in the long run ?

A

In the long-run a firm will stop producing and shut down if it can’t make normal profit.
A firm can’t make normal profit if the market price is below the minimum average total cost.

117
Q

Are mergers always successful for businesses?

A

Define mergers
Mergers are a form of external business growth whereby firms acquire other businesses who are typically suppliers, distributors or competitors. The Asda-Sainsburys proposed merger is an example of horizontal integration between competitors.

Mergers are successful
Firms can acquire competitors which reduces the competition that a business faces. Market share also increases and so companies can benefit from increased economies of scale which may lead to lower average costs. These can then be passed on to consumers in the form of lower prices. Growth from merging can also be rapid, for example, Facebook’s acquisition of WhatsApp in 2014 gave it 700 million customers instantly.

Mergers are not successful
Mergers can be disastrous. The merging of businesses usually requires operations teams to combine and, if the firms are large, this can be complex and costly. This can lead to diseconomies of scale. Different management styles and work cultures may also come into conflict. For example, Daimler’s merger with Chrysler in the late 1990s suffered from this and they separated in 2007.

Evaluate
Overall, mergers are not always successful and more than half fail. The success of a merger depends on whether the firms will be able to synergise production and the workforces. It may also depend on the extent to which market share will increase and whether the firms can take advantage of scale economies.

118
Q

Bounded rationality
Herbert Simon developed a theory which argued that firms aim to reach a minimum requirement in a number of areas like profit, revenue, and sales.
He believed that profit maximisation is not always possible due to bounded rationality.

What is this theory called ?

A

Satisficing

119
Q

How might long-run average costs increase with output for a firm?

A

Internal diseconomies of scale
Diseconomies of scales describe the situation average costs rise as output rises. Internal diseconomies of scale happen when a firm’s growth causes the LRAC to rise. If output rises, the firm is likely to get bigger. This growth can lead to more layers of management, with a higher likelihood of miscommunication & poor co-ordination, with costs rising as a result.

External diseconomies of scale
External diseconomies of scale is when the change that brings higher costs about happens outside of the firm. Increased market performance means raw materials may go up in price. This will increase average cost for all firms in the industry. For example, 3 new coffee chains entering a market could cause LRAC to rise for all firms because they may be competing for inputs like baristas and coffee beans.
