Q

What demand side factors affect labour productivity?

A

When demand is high businesses make more intensive use of existing inputs e.g. overtime shifts

High demand creates increased profits which can then be used to fund investment in newer more efficient capital.

Q

What are the key advantages from specialisation?

A

Higher labour productivity and rising business profits

Specialisation creates a surplus output of goods and services that can be traded internationally

Lower prices cause higher real incomes and gdp growth

Q

How does specialisation increase labour productivity and business profits?

A

Learning by doing (specialisation) increases output per hour worked, higher productivity lowers the unit cost of supply. Increased productivity leads to higher profits for businesses.

Q

What are the disadvantages of a firm implementing specialisation?

A

Unrewarding, repetitive work that requires little skill can lower motivation and eventually causes lower productivity.

Workers may take less pride in work and quality suffers

Dissatisfied workers causes absenteeism to increase

People move to less repetitive jobs causing higher labour turnover and increased hiring/training costs.

Can cause structural unemployment as workers receive little training and may struggle to find employment when out of work.

Q

What are economies of scale?

A

The unit cost advantages from expanding the scale of production in the long run, the effect is to reduce average costs over a range of output.

These lower costs represent an improvement in productive efficiency and can give a business a competitive advantage, via lower prices and higher profits.

Q

What does diseconomies of scale mean for a firm?

A

A business has moved beyond their optimum size

Businesses are suffering from productive inefficiency because of organisational slack.

Worker morale can suffer which reduces productivity and increases unit cost.

Businesses may have to raise prices to cover increased costs

Lost competitiveness could lead to declining market share and a fall in the share price.

Q

What does satisficing mean?

A

Satisficing behaviour is an alternative business objective to maximising profits. It means a business is making enough profit to keep shareholders happy or it’s sufficient for investors to maintain confidence in the management they appoint.

124
Q

What does cross subsidised mean?

A

A strategy where support for a product comes from the profits generated by another product. This is usually done to attract customers to a newly introduced product by giving them a lower price. The low price is sustained by the earnings of another product sold by the same company.

125
Q

What is monopolistic competition?

A

A monopolistic competitive market is one with freedom of entry and exit, but firms can differentiate their products. There are many producers and many consumers, with a low industry concentration ratio.

Non price competition is strong and lots of consumers switching takes place.

Producers are price makers.

126
Q

What are some examples of monopolistic competition?

A 
Shoe repairs and key makers
Taxi
Sandwich bars 
Coffee shops
Hairdressing salons
Dry cleaners 
Bars
127
Q

A concentration ratio is the ratio of the combined market shares of a given number of firms to the whole market size. E.g. three firm concentration ratio.

128
Q

How does having low barriers to entry and exit an advantage to a firm?

A

This allows producers to respond to changing profit signals.

129
Q

What is a pure monopoly?

A

A pure monopolist is a single supplier that dominates the entire market, the market has a 100% concentration ratio.

130
Q

What do the UK competition and Markets authority define a monopoly as?

A

A firm that has more than 25% market share.

131
Q

How much market share does a ‘dominant firm’ have?

A

At least 40%

132
Q

If a business has a downward sloping demand curve, it is able to…..?

A

Set prices in the market as it would have price marketing power.

133
Q

How to barriers to entry help monopolists maintain monopoly power?

A

As it is more difficult to enter the market monopolists have less competition and are able to maintain their power.

134
Q

What is assumed the general objective of a monopoly?

A

Profit maximisation but the actual conduct of firms with market power is often different in each market.

Often firms with market power do not profit maximise as one of their aims as they aim to maintain their market share.

135
Q

What are potential barriers to entry to a monopoly market?

A 
Economies of scale
Vertical integration
Brand loyalty
Control of important technologies
Expertise
Goodwill
Reputation
136
Q

What is strategic entry deterrence?

A

Is any move by existing firms to reinforce their position against potential rivals.

137
Q

What are some examples of strategic entry deterrences?

A

Hostile takeover/acquisitions
Product differentiation
Capacity expansions (Exploit economies of scale)
Predatory pricing (Losses in the short run to force competitions out of the market)

138
Q

What are the main arguments against monopoly?

A

Produces a welfare loss

Prices are higher

Leads to a loss of allocative efficiency

Regressive effects on lower income households

Absence of market competition may lead to production inefficiencies (High advertising spending)

Higher prices=Lower output and lead to fewer economies of scale being used

Less drive to research and innovate as no competition so no need to improve

Monopoly may get too big leading to dis-economies of scale

139
Q

If a market has a high market concentration ratio, why may it not always signal the absence of competition?

A

It can instead signal the success of firms in providing better quality products, more efficiently than their rivals.

140
Q

What are the key advantages from Monopoly?

A

Profits can be used to fund capital investment and research

Natural monopoly benefits from significant economies of scale- leading to lower prices

Domestic monopoly faces global competition- domestic monopolies are needed to compete successfully in international markets.

Price discrimination may help some lower income consumers.

141
Q

What is a natural monopoly?

A

A natural monopoly occurs when the most efficient number of firms in the industry is one.

142
Q

Why is it most efficient to only have one firm in natural monopolies?

A

A natural monopoly will typically have very high fixed costs meaning that it impractical to have more than one firm producing the good.

143
Q

Give an example of a natural monopoly?

A

An example of a natural monopoly is tap water. It makes sense to have just one company providing a network of water pipes and sewers because there are very high capital costs involved in setting up a national network of pipes and sewage systems. To have two different companies offering water wouldn’t make sense as the average cost would be very high compared to just one firm and one network. There would also be the inconvenience of having two firms dig up the road to lay a duplicate set of water pipes.

144
Q

Why must natural monopolies be regulated?

A

Natural monopolies are incontestable and firms have no real competition. Therefore, without government intervention, they could abuse their market power and set higher prices. Therefore, natural monopolies often need government regulation.

145
Q

What is price discrimination?

A

Price discrimination is when a business charges different consumers different prices for the same good or service.

146
Q

What is 1st degree price discrimination?

A

This involves charging consumers the maximum price that they are willing to pay. There will be no consumer surplus.

147
Q

What is 2nd degree price discrimination?

A

This involves charging different prices depending upon the quantity consumed. For example:

After 10 minutes phone calls become cheaper

148
Q

What is 3rd degree price discrimination?

A

This involves charging different prices to different groups of people. E.g.

Student discounts,
Senior citizen rail card

149
Q

What are the main aims of price discrimination?

A

To increase total revenue by extracting consumer surplus and turning it into producer surplus

To increase total profit providing the marginal profit from selling to consumers is positive

To generate cash flow especially during a recession

To increase market share and customer loyalty

To make more efficient use of a firm’s spare capacity

To reduce waste and cut the cost of keeping products in storage.

150
Q

What is dynamic pricing?

A

When the market demand exceeds the available supply e.g. at peak times, the firm raises the average price to encourage more supply e.g. taxi drivers to take to the roads to the expand the supply.

151
Q

What are the benefits to the economy of a firm using price discrimination?

A

Social benefits- charging lower prices for drugs in lower and middle income countries

Making better use of spare capacity can result in less waste

It brings new customers into the market, whom otherwise may not of been able to afford it.

Profit can be used for research or innovation that increases dynamic efficiency.

152
Q

When evaluating price discrimination, what factors are against the use of it?

A

Exploitation of consumer the majority of consumers still pay more than marginal cost

If successful it reinforces monopoly power in the market

Possible use of discrimination as a limit pricing tactic and thus a barrier to entry to rival firms.

153
Q

What is an oligopoly?

A

A market dominated by a few large firms

158
Q

What are examples of strategic behaviour?

A

Tacit collusion
Price leadership
Price fixing cartel
Game theory

159
Q

A

When firms co-operate but not formally, e.g. price leadership or quiet co-operation.

160
Q

What is price leadership?

A

When one firm has a dominant position and firms with lower market shares follow pricing changes prompted by the the dominant firm.

161
Q

What is explicit collusion?

A

An explicit agreement between suppliers to avoid competition, e.g. by fixing prices or sharing a market.

162

Competitive
Destroyer/Predatory
Psychological
Penetration

164
Q

Who are the winners of a price war between firms?

Non price competition refers to all forms of competition other than through the price mechanism.

167
Q

What are examples of non price competition?

A 
Quality of product
Design
Environment impact
After sales services/replacement parts

173
Q

What are global brands?

A

The ultimate brands- “household” names based on familiarity, availability and stability that are effective across global markets. E.g. Mcdonalds

174
Q

In an oligopoly why do firms not raise prices?

A

Rivals are assumed to not follow price increases so the the acting firm will lose market share- therefore demand will be relatively elastic and a rise in price will lead to less revenue.

175
Q

In an oligopoly why do firms not reduce prices?

A

Rivals are assumed to match the price fall to avoid a loss of market share. If this happens demand will be more inelastic and a fall in price will also lead to a fall in total revenue.

176
Q

Why do oligopolies focus on non price competition?

A

As an increase or decrease in the price a good or service offered by firm will result in a decrease in total revenue either way.

177
Q

Why do oligopolies collude?

A

Collusion lowers the cost of competition, e.g. expensive marketing wars which can run into millions.

Collusion reduces uncertainty in a market

Higher profits increase producer surplus/ shareholder value leading to higher share prices

178
Q

Collusion in an oligopoly is easier to achieve when:

A

Industry regulations are ineffective- a source of regulatory failure

Penalties for collusion are low relative to the gains in profits-(fines therefore do not act as a deterrent)

Few firms in the market

Participating firms have a high percentage of total sales- allowing them to control market supply

Firms can communicate well and trust each other and they have similar strategic objectives

Products are standardised

Brands are strong so that consumers will not switch demand when collusion raises prices.

179
Q

Why do businesses join together to form cartels and collude?

A

Businesses in a cartel recognize their mutual interdependence and act together- the main aim is to maximise joint profits.

180
Q

Why do business cartels break down?

A

Economic recession creates spare capacity

Entry of non cartel businesses into market

Over-production within the cartel- falling prices

Whistle blowers expose cartel to authorities

181
Q

What are the aims of a business cartel?

A

To restrict production to maximize their total profits.

182
Q

How may entry of non cartel businesses into the market cause business cartels to break down?

A

Other firms who are not members of the cartel may opt to sell just under the cartel price, resulting in decreased demand for the cartel business.

183
Q

How could a recession cause a business cartel to break down?

A

Falling market demand creates excess capacity in the industry and this puts downward pressure on profits and cash-flow in the cartel.

184
Q

How could whistle blowers cause a cartel to fail?

A

The exposure of price fixing by a whistle blower firm, would mean that the authorities would issue large fines to all the firms associated with the cartel and causing a breakdown in the cartel.

185
Q

What are the costs to the economy of oligopoly collusion?

A

Damages consumer welfare-
Higher prices/lost consumer surplus
Loss of allocative efficiency
Hits lower income families has a regressive impact.

Absence of competition hits efficiency
X-inefficiencies leads to higher unit costs
Less incentive to innovate/ loss of dynamic efficiency
Output quotas penalize firms who want to expand.

Reinforces the cartels monopoly power
Harder for new businesses to enter the market this reduces market contestability

186
Q

What are X-inefficiencies?

A

X Inefficiency occurs when a firm lacks the incentive to control costs. This causes the average cost of production to be higher than necessary. When there is this lack of incentives, the firm will not be technically efficient.

187
Q

What is dynamic efficiency?

A

Dynamic efficiency is concerned with the productive efficiency of a firm over a period of time.

A firm which is dynamically efficient will be reducing its cost curves by implementing new production processes. Dynamic efficiency will enable a reduction in both SRAC and LRAC.

188
Q

What are the benefits to the economy of oligopoly cartels?

A

Possible increase in capital investment projects
Research and development leading to dynamic efficiency
Higher wages for employees-more consumption

189
Q

What is a co-operative outcome?

A

An equilibrium in a game were the players agree to co-operate.

190
Q

What is a dominant strategy?

Q

What is Nash equilibrium?

A

Any situation where all participants in a game are pursuing their best possible strategy given the strategies of all of the other participants.

192
Q

What is Tacit collusion?

A

Where firms undertake actions that are likely to minimize a competitive response.

E.g. avoiding price-cutting or not attacking each other’s market.

193
Q

What is whistle blowing?

A

When one or more agents in a collusive agreement report it to the authorities.

194
Q

What is a zero sum game?

A

An economic transaction in which whatever is gained by one party must be lost by the other.

195
Q

What is pareto efficiency/optimal?

A

Pareto efficiency is said to occur when it is impossible to make one party better off without making someone worse off.

196
Q

What is pareto improvement?

A

A Pareto improvement is said to occur when at least one individual becomes better off without anyone becoming worse off.

197
Q

What is break even pricing?

A

Break-even price is when the price of the good or service is equal to the average total cost.

198
Q

What is cost plus pricing?

A

Where a firm fixes the price by adding a fixed percentage profit margin to the average cost of production.

199
Q

What is limit pricing?

A

Limit pricing is a pricing by a firm to deter entry or the expansion of fringe firms. The limit price is below the short run profit maximizing price but above the competitive level.

200
Q

What is peak pricing?

A

When a business raises its prices at a time when demand has reached a peak might be justified due to higher marginal costs of supply at peak times.

201
Q

What is penetration pricing??

A

Pricing policy used to enter a new market usually by setting a low price.

202
Q

What is predatory pricing?

A

Predatory pricing is a deliberate strategy of driving competitors out of the market by setting low prices or selling below average variable costs.

203
Q

What is a contestable market?

A

A contestable market occurs when there is freedom of entry and exit into the market. In a contestable market, there will be low sunk costs.

204
Q

What are sunk costs?

A

Costs which can’t be recovered when leaving the market

205
Q

What are the conditions for a contestable market?

A

A pool of new businesses who are willing and ready to enter the market.

No significant entry or exit costs- this lowers the risk of market entry

Equal access to available industry technologies

Higher rates of customer switching (low brand loyalty)

206
Q

What are some examples of Sunk costs?

A

Asset-write-offs

Project cancellation costs

The loss of business reputation and goodwill

207
Q

What is efficiency?

A

Is about society making optimal use of scarce resources to help satisfy changing wants and needs.

208
Q

What is allocative efficiency?

A

When no-one can be made better off without making someone else worse off.

Where production is at an output level where the price equals the Marginal Cost (MC) of production

209
Q

What is productive efficiency?

A

Productive efficiency exists when producers minimize the wastage of resources. In the economy there can only be an increase in production of a good if there is a decrease in production of another.

210
Q

Where is productive efficiency on a PPF?

A

When a firm operates at its PPF its productive efficient.

211
Q

Where would productive efficiency be seen on a average cost curve?

A

The lowest point.

212
Q

What is innovation?

A

Changes to products or production processes- innovation is important in delivering improvements to dynamic efficiency leading to better goods and services.

213
Q

What is product innovation?

A

Small scale and frequent

214
Q

What is process innovation?

A

Changes to the way in which production takes place or is organised.

215
Q

Where is productive efficiency on a average cost curve?

A

Productive efficiency is when a firm is operating at the lowest point of their average cost curve.

216
Q

What does X-inefficiency mean?

A

X Inefficiency occurs when a firm lacks the incentive to control costs. This causes the average cost of production to be higher than necessary. When there is this lack of incentives, the firm will not be technically efficient.

217
Q

What can cause shifts in demand for labour?

A

A change in consumer demand

A change in the price of the product

A change in productivity of labour

Employment subsidy

A change in the cost of capital equipment

Wage rate

218
Q

What is marginal revenue product of labour?

A

Is the extra revenue generated when an additional worker is employed.

219
Q

If a firm is trying to maximize profits it should employ workers until?

A

Marginal revenue product of labour=Marginal cost labour

220
Q

What does a elastic labour demand curve look like?

A

Less steep like a normal demand curve

221
Q

What does a inelastic labour demand curve look like?

A

Steep demand curve.

222
Q

What does elasticity of labour demand measure?

A

The responsiveness of demand when there is a change in the wage rate.

223
Q

What does elasticity of labour demand depend on?

A

Labour costs as a percentage of the total costs of the firm. When labour expenses are a high percentage of total costs labour demand is more elastic.

Ease and cost of substitution: Labour demand is more elastic when a firm can substitute easily and cheaply between labour and capital inputs.

Price elasticity of demand for the product: If the product has inelastic demand then higher costs can be passed on.

Time period: In the long run is it easier for firms to switch factor inputs, e.g. bring more capital in perhaps replacing labour.

224
Q

What is labour supply?

A

Hours that people are willing and able to supply at a given wage rate.

225
Q

What factors are there that influence the supply of labour?

A 
Real wage rate
Extra pay
Job risk
Job security
Career opportunities 
Anti social hours
Generosity of occupational pensions
Working conditions
Quality of training
Wages on offer in substitute occupation
Barriers to entry (Degree)
Non-Monetary characteristics of specific jobs(Job risk, need to work anti-social hours)
Net migration of labour
Demographic factors
Peoples preferences.
226
Q

What factors affect the elasticity of supply of labour?

A

Nature of skills and qualifications required to work

Specific skills and education requirements=More inelastic

Lengthy and costly training periods=more inelastic

Skill factor needed, low skill=more elastic

Time period:
in the SR supply curve tends to be inelastic

Takes time for people to respond to changes in wages

227
Q

What is the equilibrium wage rate?

A

The equilibrium wage rate is at the intersection of the supply and demand for labour.

228
Q

What is wage differentials?

A

The difference in wages between workers with different skills in the same industry, or between workers with comparable skills in different industries or localities.

229
Q

What are some key causes of wage differentials in the labour market?

A

Compensating wage differentials

Different skill levels

Differences in labour productivity

Trade unions

Artificial barriers to labour supply

Employer discrimination

230
Q

How can compensating wage differentials cause wage differentials?

A

When firms reward people for risk taking, working in poor conditions and during unsocial hours. These create wage differentials as employees whom do these things get paid more.

231
Q

How can people having different skill levels cause wage differentials?

A

Market demand for skilled labour grows more quickly than for semi-skilled workers. This increased demand results in wage differentials as firms will pay more for these skilled laborers.

232
Q

How can differences in labour productivity cause wage differentials?

A

Workers whose efficiency is high and generate revenue for a firm often have higher pay.

233
Q

How can trade unions cause wage differentials?

A

Trade unions might use their collective bargaining power to achieve a markup on wages compared to non-union members.

234
Q

How can employer discrimination to labour supply cause wage differentials?

A

Some employers will pay more to male employees causing wage differentials.

235
Q

What are the arguments for a higher minimum wage?

A

Poverty reduction-Increases the pay to poorer workers

Training-Encourages firm to train workers that can lead to higher productivity.

Incentives-Will improve incentives for people to look for paid work rather than stay on benefits

Anti-discrimination-Minimum wage is a way of tackling discrimination that affects younger workers.

Equity justification

236
Q

What are the arguments against a rise in the national minimum wage?

A

Loss of jobs-Higher MW adds to the cost of employing workers and might cause higher unemployment

Small businesses may struggle to make a profit- a risk of higher business closures

Competitiveness-Might make many UK businesses less competitive in some global markets

Inflation- Higher labour costs might cause higher inflation which then lowers real income for households.

237
Q

What is the Living wage policy?

A

An optional alternative to the minimum wage.

238
Q

What is the policy income tax reforms?

A

Cutting the basic rate of income tax or lifting the tax free allowance will improve work incentives

239
Q

What is the policy benefit reforms?

A

Linking benefits to participation on work programs

240
Q

What is the policy measures to raise labour productiviity?

A

Most important in the long run- higher productivity lifts wages and incomes.

Geographical immobility- Barriers to changing local to find a new job

244
Q

How does disincentives to find/take work cause labour market failure?

A

Unemployment trap where economic incentives to take a job are poor, leading to people staying unemployed

Poverty trap where there are disincentives to earn extra income.

Geographical

Occupational

249
Q

A

Factor immobility occurs when it is difficult for factors of production (e.g. labour and capital) to move between different areas of the economy.

250
Q

A

When it is difficult to move from one geographical area to another.

251
Q

What is occupational immobility?

A

Difficultly to move from one type of work to another

252
Q

What are causes of occupational immobility?

A

Skill gaps

Training gaps

Experience gaps

Confidence and motivation

253
Q

How can skill gaps cause occupational immobility?

A

New jobs may require different skills from those that unemployed workers can offer.

254
Q

How can training gaps cause occupational immobility?

A

Unemployed workers may not have access to affordable training schemes that would allow them to improve their human capital and employabilty.

255
Q

Stimulate stronger work incentives
Higher minimum wage or living wage
Reductions in income tax/national insurance
Welfare reforms to reduce the risk of the povery trap

258
Q

Women more likely to do part time jobs. In 2010, some 88% of men work full-time, but only 58% of women worked full-time. Part-time work tends to be lower paid and have fewer opportunities for job promotion.

261
Q

What is a monopsony in labour markets?

A

A monopsony occurs when there is one major employer and many workers seeking to gain employment.

If there is only one main employer of labour, then they have market power in setting wages and choosing how many workers to employ

262
Q

What are the problems with monopsony in the labour markets?

A

Monopsony can lead to lower wages for workers. This increases inequality in society.

Workers are paid less than their marginal revenue product.

Firms with monopsony power often have a degree of monopoly selling power. This enables them to make high profits at the expense of consumers and workers.

Firms with monopsony power may also care less about working conditions because workers don’t have many alternatives to the main firm.

263
Q

What is the profit maximising employment level for a monopsony employer?

A

When Marginal cost of labour is equal to the Marginal revenue of product labour.

264
Q

What are two disincentives to being part of the labour market?

A

The poverty trap affects people on low incomes. It creates disincentive to look for work or work longer hours because of the affects of the tax and benefits system.

266
Q

What is the unemployment trap?

A

When the prospect of the loss of unemployment benefits dissuades those without work from taking a new job- this creates a disincentives problem in the labour market.

267
Q

A

This might lead to an excess supply of labour and a contraction of total employment.

269
Q

Will trade unions have better success raising wages for their members if the demand for labour is elastic or inelastic?

A

Inelastic as there will be less substitutes/alternatives available to the firm meaning that there is a greater chance of success.

270
Q

Has trade union membership been increasing or decrease in recent years?

A

Decreasing.

271
Q

A

Measures to reduce entry barriers in an industry

Higher taxes on monopoly profits e.g. a windfall tax.

287
Q

Evaluate the effectiveness of price capping in an industry?

A

To be effective the capped price must be set by the regular below the normal profit maximizing price.

A price cap lowers the monopoly’s super-normal profit made by dominant firms in the market

May stimulate attempts to improve cost efficiency

In theory it leads to an improvement in allocative efficiency and consumer welfare

May also lead to the exit of some businesses from the industry which might actually reduce competition.

288
Q

Why may the government regulate a industry?

A

Can create incentives for firms to control their costs

Can limit the impact of monopoly power on consumers

Can encourage new firms to enter an industry

289

296
Q

What is privatisation?

A

Privatisation involves selling state-owned assets to the private sector.

297
Q

What is the case for privatisation?

A

Private companies have a profit incentive to cut costs and be more efficient and raise productivity

Government gains revenue from sale of assets
