Unit 3 Flashcards

1
Q

Why do some Small Businesses tend to Remain Small?

A

Lack of finance for expansion

Fear of expansion

Avoiding diseconomies of scale- in a quickly grown firm there could be poor organisation, x-inefficiency, or having to higher wages

Providing niche products to maximise profit- due to more inelastic demand

Providing a more personal service

Acting as local monopolies

Q

What are the Motives for the Growth of Firms?

A

To generate more profits

To benefit from economies of scale, meaning lower costs of production

To get more market power

Firms may want to diversify; so if sales drop in 1 market they can still generate sales

Senior managers may wish to grow, to control a larger business

Q

What is the Principal-Agent Problem?

A

When the agent makes decisions for the principal, but the agent is inclined to act on their own interests, rather than those of the principle.

e.g. Shareholders and managers have different objectives which may conflict.

Can be linked to the theory of asymmetric information

Q

What are Not-For-Profit Organisations?

A

A not-for-profit organisation has a goal which aims to Maximise Social Welfare.

They can make profits, but they cannot be used for anything apart from this goal and the operation of the organisation.

Q

What are Public Sector Organisations?

A

When the government has control of an industry.

There could be natural monopolies in the public sector- where only 1 firm may provide something, because it is insufficient to have multiple sets

Some public sectors yield strong positive externalities (e.g. public transport and education)

Q

What are the Incentives of Public Sector Organisations?

A

Public sector industries have different objectives to private sector industries, which are mainly profit driven.

Social welfare may be a priority of a public sector industry. It could also lead to a fairer distribution of resources

Q

What are Private Sector Organisations?

A

When a firm is left to the free market and private individuals

Benefits:
1) Firms have to produce the goods and services consumers want, which increases allocative efficiency and might mean goods and services are of a higher quality

2) Competition might also result in lower prices. This is because firms operating on the free market have a profit incentive, which public sector firms do not.

Q

What are the advantages of internal growth?

A

Easier for the owner to manage and control the direction the business goes.

Relatively low risk

Firms grow by building on their own strengths, and using their own funds; which builds up less debt, making it more sustainable.

Q

What are the constraints on business growth?

A
  1. Size of the market
    Small market- firms only access a limited consumer market, and so there’s limited opportunities for innovation and expansion
  2. Access to finance
    Smaller/ Newer firms are seen as more risky, and so get less loans. With insufficient credit, firms can’t invest + grow, nor innovate
  3. Owner objectives
    Owners’ objectives may be different- e.g. Maximising social welfare, maximising profits, environmental objectives, personal gain (reputation)
  4. Regulation
    Red tape can limit the quantity of output a firm produces. They also impose taxes (corporation tax, environmental laws + taxes)

Q

What are the reasons for demerging?

A

Lack of Synergies: A synergy is when creating a whole company is worth more than each company on its own. Without this, firms are likely to demerge because they will be worth more.

Growth of businesses at different rates: The faster growing part might be separated

Diseconomies of Scale: If the firm is so large that DoS start to occur, the firm may choose to split

Focused Companies: Firms may grow faster if they focus on a few markets, rather than several

Lack of resources: If firms can no longer invest the business due to a lack of a resources, they might sell off a part

Selling off parts of the firm can raise finance

Q

What is the law of Diminishing Marginal Returns?

A

Adding more units of a variable input to a fixed input increases product and reduces cost at first.

After a certain amount of input, the marginal increase in output becomes constant.

Eventually, an increase in input will lead to a fall in output/ increase in cost.

Q

Why does MC cut AC at its lowest point?

A

When MC < AC, AC falls.
When MC > AC, AC rises.
When MC = AC, AC doesn’t change.

At first, MC < AC, and thus AC falls until they meet. After that, MC > AC, and so AC rises.

Q

Why is the MC curve a J-curve?

A

( i don’t think you have to learn this)

The MC curve is a reflection of the MP curve (via the x axis)

MP increases until DMR comes in. When this happens, each worker is less productive for most of the time, and so the MP falls, and thus MC rises.

Q

What is an Evaluation point regarding Diseconomies of scale?

A

Depends on the Output:

If they’re performing before the minimum efficient scale, they’ll not reach diseconomies of scale

If they’re after the minimum efficient scale, they may be able to stay at that low cost for a while before the cost coming back up

Also: If fixed costs are too high, it will take them forever to get to the minimum efficient scale; yet alone diseconomies of scale

Q

What does the LRAC curve look like, and why?

A

In the short run, firms want to lower their cost and avoid DMR, and will do this by expanding their capital. This shifts the SRAC curve to the right. Firms keep on doing this, to not be constrained to the amount of capital they have, and to avoid DMR

The LRAC curve enveloped the SRAC curves, where it is always equal to or lower than the SRAC curve.

SRAC falls at first, then rises due to DMR
LRAC falls at first, then rises due to economies of scale.

Marketing: Firms can divide their marketing budgets across larger outputs (e.g. dubbed adverts)

Financial: Banks are willing to give out cheaper loans to firms

Technical: Larger firms use smaller scale machinery + factories, which leads to lower costs of production per unit

Managerial: Firms can specialise, and divide their labour

Q

What are the Types of External economies of scale?

A

Labour: Often a pool of skilled labour will develop in areas in which similar firms operate (e.g. Sillicone Valley)

Ancillary Services: Often support industries (e.g. suppliers) will develop in areas in which similar firms operate. The growth of tourism and travel agents has led to the growth in travel insurance.

Good Reputation: If a country or area builds up a good reputation for producing a good quality product, all the firms in the industry benefit from this.

Improved Infrastructure: The growth of an industry can encourage the government or the private sector to improve infrastructure that services the industry.
(e.g. growth of tourism in the UK has led to the expansion of UK airports

A

Normal Profit:
The minimum required to keep entrepreneurs supplying their enterprise.
It’s when TR = TC
It is considered to be a cost, and so included in the costs of production

Supernormal Profit:
The profit above normal profit
TR > TC

Loss:
When firms fail to cover their total costs

Q

What is the Short Run and Long Run Shut Down point?

A

A firm which profit maximises continues to operate in the short run if P > AVC –

When shutting down, no variable costs are incurred by the firm. However, fixed costs have to be paid whether the firm shuts down or continues to produce. This means fixed costs are not considered when a decision to shut down is being made.

The shut-down point is P < AVC, when variable costs cannot be covered. This is at the lowest point on the AVC curve.

When a firm shuts down, it is a short run decision. This means production is only temporarily stopped.

However, in the long run, the firm can leave the industry. This will happen when TR < TC.

Q

Where does the Shut Down Point occur in the short run?

A

The short-run shut-down point occurs when AVC=AR. Firms shut down when AVC > AR

AR>AVC: each additional unit sold will reduce the size of any losses and go towards covering fixed costs. The firm will be better off continuing to operate as they will be reducing the size of their losses.

Firms will shut down when AVC>AR because every additional unit sold will add to losses.

Achieved when the value consumers place on a good or service (reflected in the price they’re willing to pay) equals the cost of the resources used up in production

AR / P = MC

(P=AR= Demand, MC = Supply)

Q

What is Productive Efficiency?

A

About minimised cost and maximised output; exploiting all economies of scale

All resources are being used, and EoS are exploited. It occurs at the minimum point on the AC curve. It’s good to the consumer if the low cost is passed on to them as a low price

What is Dynamic Efficiency?

A

Efficiency over a period of time. It focuses on changes in the amount of consumer choice available in markets, together with the quality of G+S available.

Q

What is X Efficiency?

A

When there is no waste

Any Point on the AC Curve

Libenstein (1966) pointed to potential cost inefficiencies arising from a lack of effective competition within a market. Companies that face no or little real competition often allow their fixed costs to rise (e.g. Monopolies)

Q

How does a Supernormal Profit making firm in a Monopolistic Competition go to Normal Profit in the Long Run?

A

In the long run, supernormal profits will be eroded because new firms will enter the market owing to lack of barriers to entry.

The entry of new firms will increase supply, shifting the average revenue curve downwards to the point where AR=AC, as in the diagram.

Q

What would happen if a firm in an Oligopoly Increased the Price of their product?

A

Elastic Curve:

A firm increases the price

Those demanding that firm’s product will new switch to the substitutes
They lose market share (elastic demand- a price inc. will reduce a lot of demand)

Q

Why do prices tend to remain Stable in an Oligopoly?

A

Total revenue is maximise ‘at the kink’.

If price increases and demand is elastic, total revenue falls.
If price decreases and demand is inelastic, total revenue decreases.

As a result of the above, prices tend to remain stable as firms are reluctant to change prices up or down

136
Q

What is Overt Collusion?

A

A price-fixing agreement with a producer cartel responsible for allocating output/supply within the market

137
Q

What is Tacit Collusion?

A

A dominant firm is the price leader, and others follow

138
Q

Are Cartels legal or illegal?

A

Illegal

Firms that operate a cartel can now be fined up to 10% of their UK turnover for up to 3 years

139
Q

When is Collusion Easier?

A

Collusion is easier when..

There is only a small number firms in the industry (??)
The industry has substantial high barriers (??)
Firms output can be easily manipulated (??)
Total market demand not too variable
Low YED, Inelastic PED

140
Q

What is Price Leadership?

A

Price leadership occurs when one firm changes their prices, and other firms follow.

Other firms are often forced into changing their prices too; otherwise they risk losing their market share.

The price leader is often the 1 judge to have the best knowledge of prevailing market conditions

This explains why there is price stability in an oligopoly

141
Q

What is Game Theory?

A

Game theory refers to the interdependence between firms in an oligopoly.

It is used to predict the outcome of a decision made by one firm, when it has incomplete information about the other firm.

142
Q

What is the Prisoner’s Dilemma?

A

A model based around two prisoners, who have the choice to either confess or deny a crime.

The consequences of the choice depends on what the other prisoner chooses.

The two prisoners are not allowed to communicate, but they can consider what the other person is likely to choose.

This relates to the characteristic of uncertainty in an oligopoly.

143
Q

What is meant by the Dominant Strategy?

A

The dominant strategy is the option which is best, regardless of what the other person chooses.

This is for both prisoners to confess since this gives the minimum number of years that they have to spend in prison.

It is the most likely outcome.

144
Q

What is meant by the Nash Equilibrium?

A

The dominant strategy is still higher than if both prisoners deny the crime.
However, if collusion is allowed in this dilemma, then both prisoners would deny. This is the Nash equilibrium.

A concept in game theory which describes the optimal strategy for all players, whilst taking into account what opponents have chosen.

(However: Even if both prisoners agree to deny, it would have an incentive to cheat and therefore confess, since this would reduce the potential sentence from 2 years to 1 year – this makes the Nash equilibrium unstable)

145
Q

What is meant by Price Strategies?

A

When firms use the price of their product to influence market share.

It’s not very much used, as prices tend to be stable

146
Q

What are the Types of Pricing Strategies?

A

Price Wars
Predatory Pricing
Limit Pricing

Psychological Pricing: Giving prices that end in 9; It’s psychologically seen as a separate, cheaper price. (eg 99p vs £1)

Price Skimming: Giving a high price at the launch of a product. Once the top end of the market (those willing to pay the most) has been ‘skimmed’, they lower their prices. iPhones tend to do this.

Price Penetration: Giving a low price initially, in order to gain market share/ customer base/ hope. This tends to occur when the business is targeting a mass market

Loss Leader: When a business sets the price below the cost of the product. This can attract customers to a store, where they will also buy additional products. Some firms sell the core product as a loss leader and make additional sales by selling accessories of the product

147
Q

What is meant by Non-Price Strategies?

A

When firms don’t use the price of their product to influence market share. These aim to increase the loyalty to a brand, which makes demand for a good more price inelastic.

These strategies are mainly used within firms in an oligopoly

148
Q

What are the Types of Non-Price Strategies?

A

Advertising and Marketing: Used to make their brand more known, and influence consumer preferences. However, it’s unknown how significant A+M is to each firm- if it’s ineffective, this leads to more sunk costs, which are unrecoverable

Customer service: e.g. Having more available delivery times, longer opening time, after sales service (guarantees + warranties, etc)

Differentiation of the product: e.g. Brand name, logo, catchphrases, unique selling point. If firms can increase brand loyalty, demand comes more price inelastic. This attracts + keeps customers, increasing market share.

Quality of products

149
Q

What are the Benefits of Collusion?

A
  1. Industry standards could improve
    (especially true in the pharmaceutical industry/ car safety technology; as firms can collaborate and improve on it.)
  2. Excess profits could be used for investment, which might improve efficiency in the long run. It may also be used on dividends.
  3. It saves on duplicate research + development
  4. By inc. their size, firms can exploit economies of scale, leading to lower prices.
150
Q

What are the Costs of Collusion?

A
  1. There’s a loss of consumer welfare (as prices are raised + output is reduced)
  2. Less competition means efficiency falls
  3. Reinforces the monopoly power of existing firms, making it hard for new firms to enter
  4. Lower quantities supplied leads to a loss of allocative efficiency.
151
Q

What are Price Wars?

A

Price Wars occur when price cutting leads to retaliation and other firms cut prices, meaning the original firm again wants to cut prices.

+: The lower prices increase demand; Consumers benefit from low prices

-: All firms lose revenue.

152
Q

What is Predatory Pricing?

A

Cutting prices below the average cost of production. (It can even go below AVC)
This is a short term measure only, and once other firms are forced out of the market they rise their prices back up

This is almost always illegal.

+: Forces firms out of the market

  • :Illegal
  • :Is it really worth it in the long term?
153
Q

What is Limit Pricing?

A

It ensures the price of good is below that which a new firm entering the market would not be able to sustain. Potential firms are therefore unable to compete with existing firms.

  • : The low profits received by that firm dissatisfying shareholder, since they receive lower dividends

Q

What is a Natural Monopoly?

A

A firm who managed to enter the market first, and so have huge cost advantages.

156
Q

What is a Monopoly?

A

A situation in which the market is dominated by one seller/producer.

(By law, it occurs when 1 firm has a market share of at least 25%)

156
Q

Why do Natural Monopolies occur?

A

Costs are so expensive; it’s wasteful for others to join the market, duplicate it and be in business.

It’s also pointless, as the cost advantages are so high it can drive other competition out of the market

It just makes sense for one firm to be operating

157
Q

What are the Assumptions/ Characteristics of a Monopoly?

A

Only one firm in the industry/country;
High barriers to entry, preventing new firms from entering the market
Short-run profit maximiser
Price Makers

157
Q

What are some Examples of Natural Monopolies?

A

Rail Network
Water Utility
Gas Pipelines

All of these require huge fixed costs to run, and all are needed for the general consumption of society

158
Q

What does a Monopoly look like in the Short Run?

A

It makes supernormal profit, because high barriers prevent new businesses from entering the market

158
Q

What does a Natural Monopoly Diagram look like?

A

http://www.economicsonline.co.uk/Business%20economics%20graphs/Natural-monopoly-Basic.png

Due to ridiculously high fixed costs, it takes forever for firms to reach the minimum efficient scale

159
Q

What does a Monopoly look like in the Long Run?

A

It makes supernormal profit, because high barriers prevent new businesses from entering the market

159
Q

What happens when Naturally Monopolistic firms produce at a Low Quantity?

A

http://www.economicsonline.co.uk/Business%20economics%20graphs/Natural-monopoly-Basic.png

They get supernormal profit, but the quantity is quite restricted. This is hugely concerning for the government, because people who need their product to survive can no longer get it.

This then leads to regulation to produce an output at allocative efficiency (AR = LRMC)

This, however, is lower then LRAC, leading to loss. This loss is in fact huge due to the large quantity

The government starts to understand this, so they subsidise the firm so they won’t be in loss

160
Q

What factors influence Monopoly Power?

A

Barriers to Entry
Number of Competitors
Advertising
Degree of Product Differentiation

161
Q

What barriers to entry are there in a monopoly?

A 
Patents
Limit pricing
Cost advantages
Advertising + Marketing
Research + Development expenditure
Sunk Costs
International Trade restrictions
162
Q

How does advertising affect monopoly power?

A

Advertising can increase consumer loyalty, making demand price inelastic, and creating a barrier to entry

163
Q

How does the degree of product differentiation affect monopoly power?

A

The more the product can be differentiated (through quality, pricing and branding), the easier it is to gain market share.

this is because the more unique the product seems, the fewer competitor the firm faces (a bit like a niche product)

164
Q

What are the advantages to a monopoly?

A
  1. Abnormal profit means:
    ● finance for investment to maintain competitive edge
    ● reserves to overcome short-term difficulties and provide funds for research and development / invention and innovation
  2. Cross-subsidisation (using profits from one sector to finance losses in another sector) may lead to an Increased Range of goods or services available to the consumer.
  3. Price discrimination may raise total revenue to a point that allows survival of a product or service. It is often said that economy-class flights are funded by those flying business and first class.
  4. Monopolists can take advantage of Economies of Scale, which means that average costs may still be lower than the most efficient average of a small competitive firm
  5. Monopolies could generate Export Revenue (e.g. Microsoft generates a lot of it for the US)
  6. High profits could be a source of government revenue through taxation
165
Q

What are the disadvantages to a monopoly?

A
  1. Abnormal profit means:
    ● less incentive to be efficient and to develop new products
    ● efforts are directed to protect market dominance.
  2. Monopolists avoid undesirable duplication of services and therefore a misallocation of resources
  3. Monopoly power means higher prices and lower output for domestic consumers.
  4. Monopolies may waste resources by undertaking cross-subsidisation, (using profits from one sector to finance losses in another sector).
  5. Monopolists may undertake price discrimination to raise producer surplus and reduce consumer surplus.
  6. Monopolies lead to a misallocation of resources by setting prices above marginal cost, so that price is above the opportunity cost of providing the good.
  7. Monopolists do not produce at the most efficient point of output (i.e. at the lowest point of the average cost curve).
167
Q

What is meant by ‘Barriers to Entry’?

A

Barriers to entry are designed to block potential entrants from entering a market profitably.

They seek to protect the monopoly power of incumbent (existing) firms in an industry, and therefore maintain supernormal (monopoly) profits in the long run.

Barriers to entry have the effect of making a market less contestable.

168
Q

What do Patents do?

A

Patents involve giving the firm the legal protection to produce a patented product for a number of years.

169
Q

What is meant by ‘Cost Advantages’ as a barrier to entry?

A

Lower costs, perhaps through experience of being in the market for some time, allows the existing monopolist to cut prices and win price wars

171
Q

What is Price Discrimination?

A

Price discrimination is when a firm charges different consumers different prices for an identical product, by exploiting the fact that different consumers have a differing willingness and ability to pay.

It happens in a monopoly.

172
Q

What are some Ways to Split the Market?

A

Time (peak/off-peak)
Location (e.g. East London vs. Central London)
Income (high/low income)
Age (barbers)
Gender (car insurance is cheaper for females)

173
Q

What are the Degrees of Price Discrimination?

A

First Degree Price Discrimination: occurs a firm charges each consumer the maximum price they are prepared to pay.

Second Degree Price Discrimination: when a different price is charged per unit according to how many units are purchased (e.g. petrol)

Third Degree Price Discrimination: involves charging prices to different groups of consumers who are separated into different markets

(You only need to know the third one <3)

174
Q

What are the Conditions needed for Price Discrimination?

A
  1. Monopolists must face different demand curves from different groups of buyers (elasticity of demand must differ)
  2. Monopolists must be able to split the market into distinct groups of buyers
  3. Monopolists must be able to keep to market separate at relatively low cost to prevent selling between groups

176
Q

What is the Output under Price Discrimination?

A

The 2 markets have different outputs

The whole market’s output is the sum of the 2 markets’ outputs.

177
Q

What is the Price under Price Discrimination?

A

The price in the inelastic market would be higher than the elastic market

178
Q

What are the Profits under Price Discrimination?

A

Profits from the 2 markets combined is higher than the whole market when a single price is charged.

179
Q

What happens to Consumer Surplus under Price Discrimination?

A

In 3rd degree price discrimination the monopoly is extracting consumer surplus and turn it into extra supernormal profit

One group gets the product sold at a lower price, and another gets it sold at a higher price.
(Profit = (R-C) x Quantity)

http://www.digitaleconomist.org/monopoly_2_degree.gif

180
Q

What are the Advantages of Price Discrimination?

A

Firms will be able to increase revenue. This will enable some firms to stay in businesses who otherwise would have made a loss.
(e.g. Price discrimination is important for train companies who differ prices depending on peak times)

Increased revenues can be used for research + development which benefit consumers

Some consumers will benefit from lower fares (e.g. elderly people and those who are poor)

181
Q

What are the Disadvantages of Price Discrimination?

A

Some consumers will end up paying higher prices. These higher prices are likely to be allocatively inefficient, as P>MC

Those paying higher prices may not be the poorest (e.g. adults could be unemployed, OAPs well off)

There may be administration costs in separating the markets (extra paperwork required)

Profits from price discrimination could be used to finance predatory pricing (opp. cost)

182
Q

What Evaluation points could be taken into account when discussing Price Discrimination?

A

1) How easily they can meet the conditions- It may be more difficult if:
More competition entered (increasing elasticity)
Is there any way the goods could be re-sold?
Can markets be kept geographically separate? (consider the internet)

2) The regulator may fine them

183
Q

What is a (pure) Monopsony?

A

A monopsony is a firm which is the sole buyer of resources or suppliers.
There is a single buyer in the market.

184
Q

What is meant by Monopsony Power?

A

A monopsonist has buying power in their market.

This buying power means that a monopsonist can exploit their bargaining power with a supplier to negotiate lower prices. The reduced cost of purchasing inputs increases their profit margins.
Many firms have some degree of monopsony power, which means firms have some control over their suppliers

A firm with monopsony power is able to negotiate lower prices, because their suppliers have nowhere else to sell to (there is only one buyer). They are also able to set the market price.

(suppliers accept it because the firm is well respected; and the quantity sold is huge- imagine McDonalds; big businesses can influence cheaper supply)

185
Q

What are the assumptions about Monopsonies?

A

It is assumed that monopsonists are profit maximisers.

They aim to minimise costs by paying suppliers the lowest possible price.

Monopsonists will pay lower prices to suppliers than if the market was competitive but suppliers will also supply less to the market.

186
Q

What are the Benefits of Monopsonies?

A
  1. Improved value for money; allowing an increase in productivity. Also, lower buying costs might be passed on to the customer in retail prices
  2. Lower input costs can raise profitability that can fund investment/ research +development
  3. The growth of the fair trade label and organisation is evidence of how pressure from consumers can lead to improved contracts and prices for farmers in developing countries – this increase in inome and profit will have important economic and social benefits of exporting industry
  4. Monopsony Power can give power to buyers in the face of monopoly supply or resources. For sample, cosmetic produces (e.g. L’Oreal) can charge very high prices for their products, but supermarkets good for supplies to cut their costs
187
Q

What are the Costs of a Monopsony?

A
  1. Suppliers can be squeezed out of business - The price may be so low that they can’t cover their costs, forcing it out of the market
  2. Choice for consumers could be limited, as monopsony acts as a barrier to entry for new firms
  3. Higher profits from monopsonies can mean inequality - they make higher profit, new firms can’t compete as much, and so miss out on power
188
Q

Who developed the Contestable Markets theory, and when?

A

William J. Baum, John Panzar + Robert Willig

1982

189
Q

What is a Contestable Market?

A

A contestable market exists when an entrant has access to all production techniques available to the incumbents’customers, and entry decisions can be reversed without cost.

(They can exit and enters the market easily, and without cost)

190
Q

What are the Assumptions of Contestable Markets?

A 
Freedom of entry + to exit from the industry
Low/No sunk costs
Potential for hit and run competition
Number of firms vary from one to many
Firms compete and do not collude
Firms profit maximise
Goods may be homogeneous or branded
Perfect knowledge of prices
191
Q

Why is the Threat of Competition important in a Contestable Market?

A

Prices are kept competitive, and profits are low.

Even if they haven’t entered the market, the threat will make incumbent firms behave as if they were in competition

191
Q

Why do firms want to Profit Maximise?

A

Keeps shareholders happy

Reinvestment opportunities

Greater efficiency - this lowers costs and lowers prices

192
Q

What is Hit and Run Competition?

A

When a business enters the industry, takes the profit and gets out quickly (possibly because of the freedom of entry + exit)

193
Q

What are the Implications of Contestable Markets?

A

In the long run, only normal profit is earned (due to so many businesses being in the market)

The ability to earn abnormal profit in the long run depends solely on barriers to entry + exit (how many firms are in the industry)

194
Q

How do Contestable Markets benefit themselves, and the Public Interest?

A

Contestable markets can brig the benefits of competitive markets such as:

Lower prices
Increased incentives for firms to cut costs
Increased incentives for firms to respond to consumer preferences
The firm will be closer to allocative + productive efficiency than in a monopoly
There could also be significant economies of scale, because the theory of contestable markets doesn’t require there to be 1000s of firms.

195
Q

What are some examples of low contestable markets?

A

Airlines
Banking
Energy Supplies

196
Q

What is Contestability?

A

A measure of the ease with which firms can enter/exit an industry.

Focus is on the potential threat of competition, rather than actual competition

197
Q

What is the Index of Contestability?

A

High Contestability: easier to enter + leave

Low Contestability: harder to enter + leave

198
Q

What are the Signs of High Contestability?

A 
Low levels of supernormal profits
Low barriers to entry + exit
Low concentration ratios
Low sunk costs
Low collusion levels, or other signs of oligopoly
New firms entering/ leaving the market
198
Q

Who are Stakeholders?

A

People influenced some way from the company

Owners (shareholders-want profit)
managers (want more salary)
workers (want breaks, high wages)
consumers (want low prices)
government (want revenue)
199
Q

Are all contestable markets perfectly competitive?

A

Not all contestable markets are perfectly competitive

You can be contestable, but have a differentiated product

199
Q

What is Profit Satisficing?

A

Satisficing is a mix of satisfy and sacrifice

It occurs due to divorce of ownership and control; and due to conflict between the stakeholders.

It’s important to profit satisfice, so everyone is happy

200
Q

What is the Relationship between Sunk costs and Perfectly Contestable Markets?

A

Sunk costs are a barrier to contestability.

They are costs which cannot be recovered one they have been spent. For example, advertising incurs a sunk cost. A market with high sunk costs is less favourable to enter, because the risks associated with entering the market are high.

High sunk costs are likely to push a market towards a price and output that is similar to a monopoly.

201
Q

What are the Types of Barriers to entry/exit in a Contestable Market?

A

The greater the economies of scale a firm exploits, the less likely a new firm will enter the market

Legal barriers (e.g. patents and exclusive rights)

Predatory Pricing

Limit Pricing

Some firms may employ Anti-Competitive Practices (e..g refusing to supply retailers which stock competitors)

Brand Proliferation (e.g. the many brands of laundry soaps are provided by only a few large conglomerates- which disguises consumers from actual market concentration)

The cost of making workers redundant may discourage firms from leaving an industry

202
Q

What is meant by Behavioural Economics?

A

Behavioural Economics is a field of economics which looks directly at the way human behaviour and decision-making is modelled. It refers to how individuals react and make decisions when there are changes in the economy.

203
Q

Why don’t firms choose Profit Maximisation?

A
  1. They don’t know where MC = MR is
  2. Divorce between ownership and control may lead to other objectives (managerial aims) - conflict of interest
  3. Firms could be aiming for profit maximisation in the long run
204
Q

What is Sales Maximisation?

A

The maximum level of output that can be produced without making a loss

AC = AR

205
Q

Why do firms Sales Maximise?

A

Long term strategy to gain market share

Deters new entrants who have higher costs - puts off new potential competition

206
Q

What is Revenue Maximisation?

A

The maximum level of output that can be produced, before total revenue starts to fall

MR = 0

207
Q

Why do firms Revenue Maximise?

A

Managers may wish to max revenue to satisfy managerial aims (e.g. bigger perks, bigger bonuses, move to headquarters, etc)

208
Q

What is Satisficing Behaviour?

A

This is when managers may behave in a certain way for a quiet life and therefore do not push for the profit maximising position

They do enough to keep shareholders off their backs (keep them satisfied). This is called satisficing behaviour, or profit satisficing because managers produce Satisfactory Profits, rather than maximum profits

209
Q

What is Derived Demand?

A

Demand from one thing comes from demand of another thing

Labour is derived demand; e.g. Restaurants + Chefs

210
Q

Who Supplies/ Demands for Labour?

A

Businesses demand labour

Workers supply labour

211
Q

What Factors affect demand for labour?

A

Technology/Machinery (as a substitute)

Demand for Final Product

212
Q

What Factors affect supply of labour?

A

Social Trends (more supply for certain sectors, etc)
Retirement Age
Availability of Benefits
Income Tax

213
Q

What is Wage Elasticity of Labour Demand?

A

A measurement of responsiveness of demand of labour when wages change

A change in the demand for labour in response to the change in the cost of wages

214
Q

What factors affect wage elasticity of labour demand?

A

Proportion of Labour Costs to Total Cost
Ease + Cost of Substitutes
PED for Product Being Made
Time Period to Look for Alternatives

215
Q

Why is the Labour Market a Market Failure?

A

30 million are in the UK workforce, and 2.5 million are unemployed

If resources were allocated efficiently, everyone would be employed

216
Q

What is Geographical Immobility of Labour?

A

Geographical immobility refers to barriers people moving from one area to another to find work.

217
Q

What are the reasons for geographical immobility?

A

Family + Social Ties
Lack of Employment Info
Costs (esp. into London)

218
Q

How can Geographical Immobility of Labour be Corrected?

A

Reforms to Housing Market: improve supply and reduce cost of rented properties

Specific subsidies for people moving into areas with labour shortages

Encourage part ownership

219
Q

What is Occupational Immobility of labour?

A

Occupational immobility occurs when there are barriers to the mobility of factors of production between different sectors of the economy; leading to these factors remaining unemployed, or being used in ways that are not efficient.

220
Q

What are the reasons for Occupational Immobility?

A

Structural Unemployment

mismatch of employees’ skills, and employers skill requirements

221
Q

How can Occupational Immobility be corrected?

A

More spending on Higher Education

Subsidise provision of Vocational Training

Invest in Training Schemes for the Unemployed to boost human capital

222
Q

What is the aim of Competition Policy?

A

To promote competition, make markets work better, and contribute towards improved efficiency in individual markets and enhance competitiveness of UK businesses within the European Union single market.

223
Q

What do competition policies aim to Ensure?

A

Wider consumer choice

Technological innovation, which promotes dynamic efficiency

Effective price competition between suppliers

224
Q

What are the 4 Key Pillars of competition policy in the UK and EU?

A

Antitrust + Cartels: involves the elimination of agreements that seek to restrict competition, including price-fixing and other abuses dominant firms

Market liberalisation: Introducing fresh competition in previously monopolistic sectors

State aid control: state aid measures (e.g. subsidies) to ensure that such measures do not distort competition in the single market

Merger control: involves the investigation of mergers and take-overs between firms (e.g. a merger between two large groups which would result in market domination)

225
Q

Who are the Competition Regulators for the UK economy?

A

The Competition Markets Authority (CMA) is responsible for strengthening business competition and preventing + reducing anti-competitiveness.

They began fully operating on April 1 2014; when it assumed many of the functions of the previously existing Competition Commission (CC) and Office of Fair Trading (OFT), which were abolished.

The European Union Competition Commission is another important body for the U.K. economy.

226
Q

What are Other Roles of Competition Regulators?

A

To monitor and regulate prices:
They aim to ensure that companies do not exploit their monopoly power by charging excessive prices (e.g. The EU Competition Commission put a maximum price on phones ‘roaming’ charges)

Monitoring Standards of Customer Service: Companies that fail to meet specified service standards can be fined, or have their franchise/license taken away

Opening up Markets;: encourages competition by removing barriers to entry. A key task for the regulator is to fix a fair access price for firms wanting to use the existing infrastructure (Dominating firms are forced to allow others to use its infrastructure network)

Being the Surrogate Competitor: Regulation can act as a form of surrogate competition, – attempting to ensure that prices, profits and service quality are similar to what could be achieved in competitive markets

227
Q

What are the Barriers to Entry?

A

Economies of Scale

High start up costs/ capital costs

Legal Barriers (patents, licenses, healthy + safety services, etc)

Branding and Advertising

Sunk Costs (costs that aren’t recoverable when a firm shuts down or changes. You can’t get the money back or sell it on)

Anti-Competitive Practices (eg predatory prices)

228
Q

What Power do Regulators have?

A

The OFT and CC can impose fines, enforce the break up of a monopoly, force the sale of an asset, force the dominant firm in the industry to allow others to use its infrastructure network, and put company directors/managers in prison.

Any business found to be a member of a cartel can be fined up to 10% of its worldwide turnover. Any serious types of cartel found can result in a criminal conviction

228
Q

What are the Barriers to Exit?

A

Re-Sale of Assets (if you can’t get your money back, etc)

Redundancy Costs (costly to pay for redundant workers)

Costs for Ending License Agreements (e.g. Rent. Thing of it like leaving before your mobile contract ends)

229
Q

Why does Collusive behaviour occur?

A

Collusive behaviour occurs if firms agree to work together on something. For example, they might choose to set a price or fix the quantity of output they produce, which minimises the competitive pressure they face.

229
Q

What are the two Types of Oligopolies?

A

Competitive Oligopoly

Collusive Oligopoly

230
Q

Why does Non-Collusive Behaviour occur?

A

Non-collusive behaviour occurs when the firms are competing. This establishes a competitive oligopoly.

230
Q

What is the Breakeven Point?

A

The break even point for a firm is the level of output sufficient for revenue to cover all its costs.

At the break-even price, the firm neither makes a loss or profit.

The break-even price occurs where AR = ATC

231
Q

What are some examples of Industries where Monopsony power exists/persists?

A
  1. Electricity Generators can negotiate lower prices for coal + gas supply
  2. Leading supermarkets have oligopsony power when it comes to purchasing products from businesses at earlier stages of the supply chain (meat + poultry farmers, milk producers, etc.)
  3. Low-cost airlines get a favourable price when purchasing a new fleet of aircraft
  4. Amazon’s buying power in the retail book market- it gets a better price than booksellers; giving it a competitive advantage
  5. The increasing buying power of countries - e.g. China - securing deals to buy mineral deposits from other countries (often LEDCs in Africa)
231
Q

What are the Factors that promote a Competitive Oligopoly?

A

High numbers of firms

New market entry is possible

One firm with significant cost advantages

Homogeneous goods

Saturated market (A lot of price wars and price competition)

232
Q

What are Sunk Costs?

A

They are costs which cannot be recovered one they have been spent. For example, advertising incurs a sunk cost.

232
Q

What are the Evaluation points to a Competitive Oligopoly?

A

All points involving efficiency and economies of scale within a Perfectly Competitive firm

233
Q

What are the Benefits of Behavioural Economics?

A

By integrating economics with psychology, economists can benefit from the experience psychology has in examining our behaviour. Many psychologists are teaming up with economists in an attempt to study human beings in the economic forum, the most recent team being the 2002 noble prize winners Daniel Kahneman + Vernon Smith.

For the first time, lab experiments are being used to provide serious empirical data for economists to study. These experimental economists use techniques borrowed from psychology to test human studies within a controlled environment. As methodology improves, such experiments are slowly going more credibility within the economic academia

233
Q

What are the factors promoting a Collusive Oligopoly?

A

They use Overt or Tacit Collusion (price leadership)

Small number of firms
Similar costs
High entry barriers
Ineffective competition policy

Consumer loyalty
Consumer inertia
(These two link to cheating – it doesn’t matter what you do if you don’t have these two things)

234
Q

Why are Cartels Unstable?

A

Firms can cheat on any agreement, and there’s always the threat of being caught by competition authorities.

234
Q

What are the Evaluation points to a Collusive Oligopoly?

A

All points involving efficiency and economies of scale within a Monopoly

235
Q

How can firms continue to run in the short run?

A

Firms continue to produce in the short run as long as variable costs are covered.

235
Q

What are Regulatory Bodies?

A

They are specialised regulators looking over specific industries and the companies operating within them. They work beneath the CMA and report to the CMA.

A

Government intervention to…

Control Monopolies
Control Mergers
Promotes Competition + Contestability
Protect Employees + Suppliers

257
Q

How can Monopolies be Regulated/Controlled?

A

Price Regulation

Quality Control/Performance Targets

Profit Control covering costs and adding % return on capital employed

Windfall Taxes on profit

258
Q

What is RPI?

A

RPI is the rate of inflation.
If everyone’s income rises, and the firms products rise as well, this can be seen as fair because they’re covering their costs.

However, it can go stricter.

259
Q

What is RPI-X?

A

Restricts levels by which firms can increase their prices below RPI, whilst X represents a percentage.

260
Q

Why do firms like RPI-X?

A

A firms incentive is to cut costs as low as possible below X.

This allows firms to raise price by RPI-X, but the costs have been cut more, giving a larger profit margin

Therefore, there’s strong incentives for RPI-X.

261
Q

What is RPI(+/-)K?

A

Seen a lot in the water industry.

K represents a % whereby enough profits can be made to allow for capital investment

RPI+K: RPI price increases on their own won’t generate high enough profit to sustain big capital inestments in a company

RPI-K: Prices don’t need to rise above RPI; they can rise below RPI, giving enough profit for firms to make to allow for capital investment

262
Q

What is the Price Capping Diagram?

A

https://www.tutor2u.net/_legacy/blog/files//mob_price_cap_2.jpg

263
Q

What are the Problems with Price Regulation?

A

It depends on the level of x/k; and asymmetric information can lead to bodies regulating it at a value that harms all firms

Regulating is very costly and time consuming

Regulatory Capture- those in the firm become close w/ regulators, and influence their decision as a result

264
Q

How do Quality Control/Performance Targets control Monopolies?

A

Found in trains, gas + electricity, NHS, etc.

They have to reach certain targets, or are allowed a certain amount of failure, etc.

265
Q

What are the Problems of Quality Control/Performance Targets controlling Monopolies?

A

Unintended Consequences: shortcuts may be taken to ensure targets are met, meaning the quality of service is reduced

‘Gaming the System’- the adapt to the system and change things to avoid exceeding rules, which results in inefficient service

266
Q

How does Profit Regulation control Monopolies?

A

Regulatory bodies may give a greater rate of return (which reflect high profit it will bring) if they employ more capital

Using the equation whereby costs are going to be covered, but also adding a % rate of return on capital employed.

We know that capital employed on investment is risky and costly; but it looks at paying the costs now to ensure high productivity and hopefully high profits in the future

267
Q

What are the Problems with Profit Regulation to control monopolies?

A

Asymmetric Information: They may not give the correct rate of return and harm firms

Incentive to increase costs, as they will always be covered

Incentive to Over-Employ Capital in order to get higher returns

268
Q

How do Windfall Taxes on Profit control Monopolies?

A

They don’t re-invest as much money into things that will further dominate their firm; nor can they benefit from as much economies of scale

269
Q

What are the Problems with Taxes on Profit to control monopolies?

A

Worsens monopoly outcomes

Tax exemption/evidence

Less innovation

Under-reporting of profit

270
Q

What are the Evaluation points about Monopoly Control?

A

Level of information

Costs / Benefits of Regulation - the taxpayers pay for all regulation, which is expensive

Regulatory Capture

Benefits of a Monopoly that are now controlled

These all lead to Government Failure

271
Q

What are the Merger Controls?

A

If a merger between companies creates a market share greater than 25%, competition authorities can investigate and do 1 of 2:

  1. Break up the merger if it goes heavily against public interest
  2. If they create monopoly outcomes in certain locations, they can force them to sell off their stores in those locations to promote competition
272
Q

How can Competition + Contestability be Promoted?

A

o privatisation
o deregulation
o enhancing competition between firms through promotion of small business
o competitive tendering for government contracts

273
Q

What is Privatisation?

A

The transfer of ownership of a firm/industry, from the public sector to the private sector

274
Q

What happens in Publicly Owned Firms?

A

Publicly owned firms are owned by the government, and will act in the best interests of the consumers.

Prices tend to be low and output tends to be high, and they may not know how to make profits

275
Q

What does Privatisation Cover?

A

Contracting out services
Competitive tendering
Public Private Partnerships (PPP)

276
Q

How may Privatisation involve contracting out services?

A

A government pays a private firm to carry out work on its behalf

277
Q

How may Privatisation involve competitive tendering?

A

Private firms bid/compete to gain a contract to provide a service for the government.

This firms will complete on the price and quality of the service offered

278
Q

How may Privatisation involve Public Private Ownerships?

A

A private firm works with the government to build a service for the public

An example of a PPP is a Private Finance Initiation (PFI)
A private firm is contacted by the government to run a project

In the UK, some hospitals/schools are built by a private firm, then the government leases the buildings from the firm (usually for a long period of time)

279
Q

What are the Advantages of Privatisation?

A

Increased competition means improved efficiency, lower X inefficiency

Lower taxes in the short run
(The government won’t pay for the new facility immediately)

280
Q

What are the a Disadvantages of Privatisation?

A

A privatised public monopoly is likely to become a private monopoly, so extra measures (e.g. the regulation) need to be taken to avoid this

Privatised firms means more focus on reducing cost and profits, instead of focusing on safety and quality

PFIs mean taxes for future generations

281
Q

What is meant by Regulation?

A

Rules that are enforced by authority (e.g. a government); and they are usually back with legislation

282
Q

What is meant by Deregulation?

A

Removes/ reduces regulation. It removes some barriers to entry to increase competition (particularly at monopolistic market) and tackle market failure

283
Q

What are the Advantages of Deregulation?

A

Improves resource allocation removing regulation makes the market more contestable, so new firms are more likely to enter the market

The increased rate of competition means prices go down closer to MC, and output increases

Improves efficiency

284
Q

What are the Disadvantages of Deregulations?

A

It’s difficult to deregulate some natural monopolies – these require large infrastructures (e.g. The water industry needs a pipe network). These infrastructures are expensive to build and maintain; and there’s only a need for one of them

Deregulation can’t fix of the market failures, such as negative externalities, consumer inertia or immobile factors of production

285
Q

What would happen if Deregulation + Privatisation occur together?

A

Deregulation can be used alongside privatisation of a public monopoly to prevent the privatised firm from becoming a private monopoly

Privatising can remove legal barriers to entry, and the regulation removes further barriers to entry

286
Q

How can Regulation Encourage the use of Renewable Energy?

A

The government has introduced Renewable Obligation Certificates (RCOs) to encourage the use of power generated from renewable energy sources

Energy suppliers are given a set minimum percentage of power that must come from renewable sources

Company who generate the renewable energy issued with ROCs which link to the amount of renewable energy they’ve generated. They then sell these certificates on to suppliers

Suppliers that fall short of the target % have to pay a financial penalty. The money raised from those penalties is distributed between the suppliers who did reach the target

287
Q

How can ‘enhancing competitions between firms through promotion of small business’ promote competition + contestability?

A

Small and Medium Sized Enterprises (SMEs) are important for creating a competitive market. They create jobs, stimulate innovation and investment and promote a competitive environment.

Governments aim to improve access to finance and reduce barriers to entry, which will make it easier for smaller firms to enter the market.

288
Q

What is the ‘Red Tape Challenge’?

A

The UK government has established the ‘Red Tape Challenge’, which aims to simplify regulation for businesses.

It is especially aimed towards small businesses. This aims to make it cheaper + easier to meet environmental targets and create new jobs.

289
Q

What is Creative Destruction?

A

Schumpter, an economist, proposed the idea of ‘creative destruction’ - the idea that new entrepreneurs are innovative, which challenges existing firms.

The more productive firms then grow, whilst the least productive are forced to leave the market. This results in an expansion of the economy’s productive potential.

290
Q

How can Competitive Tendering promote competition + contestability?

A

The government provides some goods and services because they are public or merit goods, and they are underprovided in the free market. The government could contract out this provision, so that private firms operate things such as roads or hospital.

The firm which offers the lowest price and best quality of provision wins the government contract. This saves the government money, since the public sector can be bureaucratic and inefficient.
The private sector has an incentive to reduce their costs, since they operate in a competitive market.It also frees the government of maintenance, since the private sector might have the expertise and knowledge to fulfil the project and maintain the infrastructure.

This can be evaluated by considering how the private sector might not meet the specification of the contract.

Moreover, the private sector firm might try and cut costs by lowering wages, and they are less likely to have social welfare as a priority.

291
Q

How can Suppliers + Employees are promoted?

A

Restrictions of Monopsony Power on Firms

Nationalisation

292
Q

How can restrictions of monopsony power of firms protect suppliers + employees?

A

Monopsony power of supermarkets lead to negotiating lower prices, meaning many farmers lose profits. In supermarket price wars, supermarkets keep negotiating lower prices from farmers, to lower their own prices.

Supplying firms are unlikely to make more than normal profit.

Governments can regulate this to ensure that farmers are receiving a fair deal.

For example, farmers in the UK might receive grants and subsidies to support their production. The CMA might investigate supermarket buying power to ensure they are not abusing their monopsony power.

293
Q

How can Nationalisation protect suppliers + employees?

A

This occurs when private sector assets are sold to the public sector. In other words, the government gains control of an industry, so it is no longer in the hands of private firms.
The railway industry in the UK was nationalised after 1945.

By nationalising an industry, natural monopolies are created. This is because it is inefficient to have multiple sets of water pipes, for example. Therefore, only one firm provides water.

Some nationalised industries yield strong positive externalities. For example, by using public transport, congestion and pollution are reduced.Nationalised industries have different objectives to privatised industries, which are mainly profit driven. Social welfare might be a priority of a nationalised industry.

The diagram shows where nationalised and privatised firms operate. Privatised firms operate at Q1 P1, which is the profit maximising level of output and price. A nationalised firm is more likely to operate at Q2 P2, which is the allocatively efficient level of output (AR=MC).

Q

What is the Impact of Government Intervention on Price?

A

Governments can prevent monopolies charging consumers excessive prices, which might result in a loss of allocative efficiency.

This can make services from utility companies, such as water, gas and electricity more affordable, which is especially beneficial to low and fixed income households.

Limiting how much a firm can increase its prices by also encourages the firm to become more efficient. This is so that they can lower their costs and increase their profit margins.

If corporation tax is high, firms might pass the extra cost onto consumers, resulting in higher prices, rather than losing their own profits.

Q

What is the Impact of Government Intervention on Profit?

A

If governments impose strict price caps, investment could be limited, since the amount of profit that a firm makes is restricted.

However, the recent fall in UK corporation tax from 21% to 20% will help firms keep more profits. The size of the fall can be evaluated- is 1% a significant fall?

Q

What is the Impact of Government Intervention on Efficiency?

A

Public Firms are more Efficient:
Private sector firms are more likely to operate at the profit maximising level of output and price. A public sector firm is more likely to operate at the allocatively efficient level of output (AR=MC).
Therefore, government intervention might lead to an increase in economic efficiency, since the objectives change from profit maximisation to maximising social efficiency.

Private Firms are More Efficient:
Free market economists argue that by operating in a competitive environment, firms have an incentive to become efficient.
This is because they are forced to lower their average costs in order to profit maximise. This makes private sector firms more productively efficient.
They might also argue that private sector firms have to produce the goods and services that consumers want in order to keep earning profits. This might increase allocative efficiency.

Q

What is the Impact of Government Intervention on Quality?

A

Governments can ensure firms are meeting minimum targets, which ensures firms focus on increasing social welfare.

For example, firms in the gas and electricity markets are regulated to ensure vulnerable groups, such as the elderly, are kept warm during colder months.
Firms which profit maximise might compromise on quality.

However, if private sector firms have the expertise and knowledge which the government might not have, then they might be able to produce goods and services of a higher quality.

298
Q

What is the Impact of Government Intervention on Choice?

A

If governments regulate monopolies and encourage the start-up and growth of SMEs, consumer choice in the market widens, since there are more firms competing.

A stringent price ceiling might force some suppliers out of the markets, which reduces the quantity supplied and narrows choice for consumers.

If governments can reduce the price of a good or service, it could allow those on low and fixed incomes to access goods and services they previously could not afford to.
