Q

What is the signalling function

A

That prices provide information to buyers and sellers about the scarcity of a good and shows them about the cost of their actions

Consumers that pays a high price for a good has a high opportunity cost
Producers that is selling a cheap good has a high opportunity cost

Q

What is the incentive function

A

Firms are incentivised by potential profit and as prices change the profitability of production changes
The function refers to movements along the supply curve

Q

What is the rationing function

A

It is the method of changing prices to decide who gets the limited good by increasing prices if there is too much demand and vise versa
This refers to extensions and contractions along the demand curve

Q

How is the problem of what to produce solved

A

Private firms compete against each other to meet consumer demand and earn profit
The firms which meet consumer preferences will make the lost profit
Consumers decide what to produce by deciding what to buy
This is called Consumer Sovereignty

Q

How is the problem of how to produce goods decided

A

Firms engage in free and open competition and are motivated by profits
The firm which uses its resources most effectively are able to sell at the lowest price and earn the most profit
This is known as competition

Q

How is the problem of for whom to produce solved

A

Prices are set at a price so quantity demanded equals quantity supplied and so price acts as a rationing mechanism and the goods given to people able to pay

Q

What are externalities

A

They are a type of allocative inefficiency when external effects are placed on third parties who are not involved in the production or consumption of the good or service
This causes too many or too few resources to be used bu over or under producing

Q

What are public goods

A

They are non-rivalry - consumption of the good doesn’t leave any less for others

There is non-excludability - No one can be prevented from enjoying the benefits of the good if they didnt pay - Free Riders

There is non-rejectability - Consumers cant decide whether to consume the good or not

Q

What problem does public goods cause

A

They have the free rider problem which means private firms cant force people to pay so providing the good isnt profitable so isnt produced

This causes the good to not be produced at all and a market goes missing

Q

Why is the new demand curve named like that

A

Because a rational buyer will be assessing the extra benefits, or marginal utility, that he will receive from consuming the good

25
What is another name for the supply curve
Marginal private cost
26
Why is the new supply curve named like that
A rational seller will think how much it costs to make the next unit of output and whether it can be sold profitably
27
Where is free market welfare maximised on a MPB and MPC graph
At the equilibrium where MPB = MPC Move to far too the right and there is more cost than benefit
28
What are the names of the demand and supply curve changed to when they take into account externalities
Marginal Social Costs Marginal Social Benefits
29
How do you measure the size of an externality
It is the vertical distance between the new supply or demand curve and the old one
30
What curve will move when the externality happens at the point of production
The MPC Supply
31
What curve will move when the externality happens at the point of consumption
The MPB Demand
32
When externalities are present what point is most allocatively efficient
MSB = MSC
33
What is the welfare or deadweight loss on an allocativly inefficient graph
The triangle that represents the net benefit to society that is lost because not enough or too many resources were produced Triangle connects the three lines together Triangle points left when the externality is negative Triangle points right when the externality is positive
34
What are goods called with positive externalities
Merit Goods
35
What are goods with negative externalities called
Demerit Goods
36
What do negative externalities lead to
Overproduction of a good
37
What does positive externalities lead to
Underproduction of a good
38
What is information failure
When consumers and producers are not fully aware of all the costs and benefits of a transaction
39
What does information failure cause
It means that it will be impossible for consumers and producers to trade the right amount of output
40
What are the causes of information failure
Consumer ignorance of the costs and benefits The disconnection in time between the costs and benefits being felt Consumers are deceived Complex Information Asymmetric Information
41
What will happen if consumers underestimate the costs or overestimate the benefits of consumption
They will overconsume the good The MPB will shift inwards when they have full information
42
What will happen if consumers overestimate the costs or underestimate the benefits of consumption
The consumers will under consume the good The MPB would move outwards when they have the full information
43
What happens when there is information failure with a demerit good
There is over consumption
44
What happens when there are negative production or consumption externalities with a demerit good
Over consumption and over production
45
What happens when there is information failure for merit goods
Under consumption and production
46
What happens when there are positive production and consumption externalities with merit goods
Under consumption and production
47
Examples of supply side policies
Deregulation of markets e.g. Banking, energy supply Industry Privatisation e.g. Royal Mail Work Visa's for occupations like doctors, engineers, vets - Points based immigration system Industry Regulation e.g. environmental laws affecting waste - drive innovation Fiscal supply side policies e.g. early year childcare Tax incentives for specific sectors - life sciences
48
What are property rights
It is when a firm or group is given the rights to a common resource
49
What are the advantages of property rights
It incentives the owners not to exploit common resources The negative externalities are internalised Will reduce the quantity to socially optimal level
50
What are the problems with property rights
Hard to distribute efficiently Enforcement costs money Hard to judge equity
51
What is 1st degree price disrimination
Charging different prices for each individual unit purchased
52
What is 2nd degree price discrimination
Prices varying by quantity sold Prices varying by time of purchase
53
What is 3rd degree price discrimination
Charging different prices to groups of consumers segmented by price elasticity of demand, income, age, sex
54
How do you show 3rd degree price discrimination in a diagram
2 different diagrams One with elastic price elasticity of demand and one with inelastic The MC is a flat line and the same for both diagrams
55
What are the advantages of price discrimination
Makes better use of spare capacity - less waste and unsold stock Helps generate cash flow for firms which can ensure they survive in recession Can help fund cross subsidy of goods and services Higher monopoly profit can finance research which improves dynamic efficiency and lead to social benefits
56
What are the disadvantages of price discrimination
Price discrimination mainly benefits producers as they turn consumer surplus into profit Can be used as a pricing tactic to reduce competition May lead to manipulation of groups with inelastic demand Can be perceived as unfair or inequitable to certain groups
57
What is the evaluation of price dicrimination
Assumes the same marginal cost of supply Impact of price discrimination depends on how the profit is used Some buyers must pay more to cover development costs Is a fair price only ever a fixed price - valuer judgements
58
What are examples of price dicrimination
Coca Cola selling cans for more when its hot Uber increasing prices during peak times Higher prices for heavier people on airlines- Samoa airlines
59
What are the conditions required for price discrimination
Firms must have sufficient monopoly power Identifying different market segments Ability to separate different groups: Requires information on the purchasing behaviour of consumers Ability to prevent re-sale (arbitrage): No secondary markets where arbitrage can take place at intermediate prices
60
What are the aims of price dicrimination
To increase total revenue by extracting consumer surplus To increase total profit To generate cash-flow especially during a recession To increase market share and build customer loyalty To make more efficient use of a firm’s spare capacity To reduce waste and cut the cost of keeping products in stock / storage
