price discrimintaion

why are adults charged higher prices and students lower prices for train tickets?

A

Adult demand = more inelastic, adults have higher incomes and less responsive to price changes. can charge adults higher prices.

Student demand = more elastic, students have less money to spend and more responsive to price changes. have to charge students lower prices.

123
Q

deregulation is where

A

regulations are removed to lower barriers to entry

the result: lower prices, better customer service and increased efficiency (taxis and uber)

124
Q

Privatisation

A

Privatisation is when the government transfers ownership of a public sector firm to the private sector.

pressure to cut costs and max profits which help improve efficiency
e.g. BT, British gas, British airways

125
Q

what usually follows privatisation?

A

deregulation -

e.g.. sky and virgin, easy jet, EDF ->competeing

126
Q

negative of privatisation

A

cut cost too low - reducing quality

increase prices - to exploit consumers

127
Q

Competitive tendering is when

A

The government outsources specific job contracts to the private sector. Private sector firms bid to win the contract, by offering the best deal - the highest quality for the lowest cost. The government then chooses the firm which offers the best value for money - and awards them the contract!

128
Q

Competitive tendering beneficial for the government because,

A

by getting private sector firms to bid against each other for the contract, private sector firms will undercut each other’s prices and offer better quality. This means the government can make sure it’s getting the best deal possible - saving money, and increasing quality.

129
Q

anti-competitive practises

A

Anti-competitive (or restrictive) practices include anything a firm might do, to restrict competition.

130
Q

Predatory pricing is when

A

a firm aggressively cuts its prices below AVC to force out competitors from the market.

In the short run, the firm incurs a loss.
But in the long run, firm forces out its competitors, so they can take over the market - restricting competition.

131
Q

price collusion

A

Collusion is when two or more firms agree to limit or restrict competition.

132
Q

anti-competitive practices include

A

Predatory pricing
price collusion
vertical integration

133
Q

If the CMA catches firms engaging in anti-competitive practices, they can:

A

Set a fine up to 10% of annual revenue
Sentence CEOs to jail time
Name and shame the firm publicly

134
Q

ways to help small business grow

A

subsidies, tax breaks and loans.

135
Q

Access to loans

A

enterprise capital funds to lend out to new business for super low interest rates to help them expand and benefit form economies of scale and compete with big businesses

this will increase contestability and decrease prices

136
Q

R&D tax breaks

A

small to medium size enterprises receive reduce tax rates if they are using their profits to invest into R&D and increase dynamic efficiency

the lower corporation tax will reduce costs and increase supernormal profit so they can do more R&D and come up with new innovations

137
Q

Subsidies

A

gov gives subsidies to small firms
the subsidie will reduce firms costs decreasing AC and MC so firms will be able to drop its prices from P max to P1

makes it easier to compete with big incumbent firms

138
Q

Nationalisation is when

A

the private sector transfers ownership of a private sector firm to the government.
e.g.. railways were nationalised prices set price =to mc allocatively efficient to maximise welfare but at this price making a huge loss

139
Q

who demands labour

A

producers

Q

Labour market diagram: Demand curve is downwards sloping because

A

when wages go down can afford to hire more workers

when wages go up they can afford to hire any more workers the demand for labour will decrease

141
Q

Labour market diagram: supply curve is upwards sloping because

A

as wages go up ppl realise they can make more money and will be willing to work more, quantity of labour supplied will increase

as wages go down ppl can’t make as much money working so will be willing to work less, quantity of labour supplied will decrease

142
Q

as wages increase

A

Workers will supply more labour and firms will demand less labour

143

a welfare loss

218
Q

social efficient point is

A

MSB=MSC

219
Q

In a free market, producers and consumers only consider their…

A

own private costs and private benefits

So they produce where MPC = MPB

220
Q

indirect taxes make production more

A

costly for firms

221
Q

after the indirect tax…

if a firm is finding it difficult to reduce pollution and another firm is finding it easy and cheap they can sell their pollution permits to the other firm so that they can producer a bit more pollution.

226
Q

the cap and trade system works by

A
  • first they government sets a cap, how much pollution it will allow each year
  • gives out permits to firms -shared between
227
Q

Firms finding it expensive to reduce their pollution will:

A

Buy permits from firms finding it cheaper to reduce their pollution

when people take advantage of being able to use a common resource, or collective good, without paying for it, as is the case when citizens of a country utilize public goods without paying their fair share in taxes.

262
Q

the government deals with incomplete information by using

A

regulation
providing information and advertising
subsidising

263
Q

Incomplete information is when

A

someone doesn’t have full information about the benefits or costs of their decisions.

264
Q

what can incomplete information lead to?

A

under consumption as consumers can see the long term benefits of consuming
also over consumptions were consumers aren’t informed of the long term costs

265
Q

Asymmetric information is when

A

one party knows more than another party in a transaction.

266
Q

the market can fail in four different ways:

A

Negative externalities, positive externalities, public goods, information gaps

267
Q

how the government can step in to address these market failures with a range of different policies

A

Taxes, subsidies, tradable pollution permits, minimum and maximum prices, regulation and information provision.

268
Q

max prices is set

A

below the eq

269
Q

examples of government failure

A
  1. distortion of the price mechanism
  2. the law of unintended consequences
  3. administration costs
  4. information gaps
270
Q

was does max price cause and why

A

excess demand/ shortage

lower price reduces the incentive to supply but more is demanded at this lower price

271
Q

maximum prices can distort the price mechanism by

A

Reducing price below equilibrium, creating excess demand

272
Q

Government failure is when

A

the government intervenes to correct a market failure but makes the allocation of resources even worse than before.

273
Q

minimum prices cause

A

excess supply/ surplus

274
Q

minimum prices can distort the price mechanism by

A

over producing and causing a wastage can lead to dumping

275
Q

Government intervention intends to correct market failures and help society…but

A

Unintended consequences eg. speed bumps

The law of unintended consequences

276
Q

explain how information gaps can lead to gov failure

A

underestimated costs

277
Q

explain how administration costs can lead to gov failure

A

regulation means people needed to regulate

278
Q

what is The law of unintended consequences

A

Government intervention intends to correct market failures and help society…but can cause Unintended consequences eg. speed bumps and ambulances

279
Q

what are the 3 functions of the price mechanism

A

Rationing
incentivising
signalling

280
Q

Free market economies allocated their resources by

A

the government

283
Q

Division of labour enables:

A

specialisation

284
Q

what is the division of labour

A

where the production process is split up into smaller tasks where each worker is assigned to a different task this allows workers to specialise

opportunity cost is

A

the lost opportunity of the next best alternative

290
Q

291
Q

Elasticity of demand for labour, tells us

A

How responsive demand for labour is to changes in wage

292
Q

few substitute =

A

inelastic demand

293
Q

lots of substitutes =

A

elastic demand

294
Q

wages are a small % of total cost

A

unresponsive inelastic demand

295
Q

wages are a large % of total cost

A

v responsive elastic demand

296
Q

in the short run, if wages increase, demand will be:

A

inelastic because there’s not enough time to find substitutes

297
Q

in the long run, if wages increase, demand will be

A

elastic because there is enough time to find substitutes

298
Q

if demand is inelastic wages will be

A

higher

299
Q

if demand is elastic wages will be

A

lower

300
Q

What are the three key factors which affect labour elasticity of demand?

A

Substitutes
% of total cost
Time

301
Q

in markets where workers require lots of skills and qualifications, supply will be:

A

inelastic

302
Q

in markets where workers require few of skills and qualifications, supply will be:

A

elastic

303
Q

in the short run if wages increase

A

workers don’t have time to train and apply for a job so workers are unresponsive to a change in price, so inelastic supply

304
Q

in the long run if wages increase

A

workers will have lots of time to apply and train for the job so elastic supply

305
Q

Derived demand is

A

demand for a factor of production (like labour) that is derived from the demand of another good/service.
