Q

Benefits of taxes

A
  1. internalises the externality

Q

3 evaluation points of indirect taxes

A
  1. if demand is price inelastic consumption may not decrease
  2. hard to assign correct level of tax as govt has imperfect info
  3. can cause unemployment as demand for the product falls.
  4. may reduce dynamic efficiency in the long term as revenues are smaller

Q

evaluation of free provision of services such as NHS or libraries

A

universal provision is not as effective as targeted provision.

Eg some areas in Cambridge may be better educated with heavier investment into school and may not need libraries. Whereas an area such as Glasgow north east

25
Q

Why may property rights benefit the environment

A

there is better incentive to maintain the resource as firms are profit maximisers

if producer have their own resource they are less likely to overexploit this for short term profits. instead they may better manage the resource to avoid extinction and guarantee longevity and sales in the future

26
Q

Why might the government intervene

A

When the invisible hand is not effective in allocating the socially maximum equilibrium

27
Q

What are the 4 economic assumptions

A
  1. There are unlimited want but limited resources
  2. There is an opportunity cost to every decision
  3. each consumer seeks to maximise their satisfaction
  4. The consumer is rational and will consider all costs and benefits before making a decision (homo economicus)
28
Q

what’s the goal of market economies

A

to maximise profits

29
Q

what’s the goal of public economies

A

to maximise social welfare and allocatively efficient

30
Q

what negative impacts may a market have if it is run by the government

(command economies)

A
  1. poor variety
  2. lack of innovation to cut down prices
  3. slower to react to changes in demand
31
Q

why do consumers over consume some demerit goods

A
  1. goods may have addictive properties
  2. information failure (undervalued long term impacts
  3. social norm
32
Q

what is the diminishing marginal utility

A

the decrease in satisfaction a consumer has by consuming an extra good or service

33
Q

what does diminishing marginal utility show

A

why the demand curve is downward sloping

34
Q

why does rising incomes leas to diminishing marginal utility

A
  1. if you have zero income then the first 100 means a lot as it finances food ect
  2. if you are earning 1000’s an extra hundred has less of an impact as it can’t improve standard of living to the extent that the first 100£ did
35
Q

how to work out tax revenue on the diagram

A

work out the size of the tax per unit. (vertical distance between the two supply curves)
the times it by the quantity where the tax is implemented

36
Q

how does an indirect tax cause an inward shift in supply

A

it increases the cost of production

37
Q

define market failure

A

This occurs when there is an inefficient allocation of resources in a free market

38
Q

what is the tragedy of the commons

A

where the is overconsumption in a particular good because rational decisions lead to an outcome which is damaging to overall welfare.

39
Q

what does the tragedy of the common assume

A

that everyone maximises utility.

eg. If one individual fisherman holds back on his catch to try and preserve overall fish stocks, it may prove futile because many other fishermen continue to catch as much as possible. The net result is that fisherman don’t have any incentive to hold back, so they might as well try and catch as much as possible.

40
Q

how can government intervention help overcome the tragedy of the commons

A
  1. limit fish catches
  2. prevents fishermen from exploiting the seas to maximise profit as they risk a large a fine or other punishment otherwise
41
Q

evaluation of government regulation

A
  1. if there is appropriate enforcement (if nobody checked speed cameras everyone would speed)
  2. depends on what the punishment is (if you only had to pay a pound for speeding you would)

This process is expensive (eg setting up speed cameras on every road in the UK)

42
Q

how can property rights help overcome the tragedy of the commons

A
  1. if a common land is given ownership, the owner is given better incentive to manage the resource
  2. in order to make long term profit
43
Q

evaluation of property rights in order to overcome the tragedy of the commons

A

the owner may be pressured by shareholders to increase profits and satisfy short term goals. this may result in the same problem

44
Q

free rider problem

A

when individuals can consume a good without paying. This is why public goods are not provided in the free market.

45
Q

why is the free rider problem so likely

A

because individuals are rational utility maximisers and will look to benefit from a public good without having to pay for it.

46
Q

what are ways information can be provided to combat obesity

A

eg the number of calories a meal is now displayed in restaurants so consumers can make the correct decision

Adverts to parents

47
Q

examples of industries that suffer from regulatory capture

A

OFGEM- office of gas and electricity markets

oil and gas drilling regulators in the US- made it easier to drill in offshore areas.

48
Q

how may regulatory capture occur

A
  1. bribery and corruption
  2. Spending time with people makes you more sympathetic to their viewpoint. If the regulator is in close contact and communication
49
Q

consumer surplus

A

the difference between the price that consumers pay and the price that they are willing to pay

50
Q

how can firms reduce consumer surplus

A

if the are a monopoly or have brand loyalty they can charge higher prices

51
Q

producer surplus

A

the difference between the price a firm receives and the price it would be willing to sell it at.

52
Q

what is regulation

A

Rules or law implemented by the government that must be abided by economic agents to encourage change in behaviour

53
Q

examples of regulation

A
  1. no diesel cars by 2030
  2. public smoking ban (can’t smoke in enclosed areas)
  3. deposit return scheme (people are charged higher prices for plastic but are given some money when recycled)
54
Q

evaluation on a ban of an inelastic good

A

a ban on a good such as cigarettes which has addictive properties isn’t likely to stop a smoker from smoking. they are just going to do it somewhere else

55
Q

evaluation of the deposit return scheme

A
  1. Some consumers may be too lazy/ busy to return their goods and the money that they could be given is too little for the utility they gain by staying at home (spending more time with family)
  2. some consumer may not need the money and therefore may not be attracted to recycle
56
Q

what is a pollution permit

A

Pollution permits involve giving firms a legal right to pollute a certain amount. The aim is to provide market incentives for firms to reduce pollution

If firms pollute less than expected they can sell them creating a market

57
Q

problems with using pollution permits

A
  1. similarly to taxes its hard to assign the right level of pollution permits.
  2. Pollution permits may be unfairly allocated. those high profit making firms will buy all permits and may increase barriers to entry as new entrants can’t pollute which may be required in some industries

THEY SHOULD BE PHASED OUT OVERTIME TO REDUCE THE RELIANCE

58
Q

Tradable pollution permits

A

Permit to reduce co2 emissions

59
Q

Tradable pollution permits chain of reasoning

A

Cap set a Q -socially optimum
Permits issued to match the cap
Firms make decision on least cost - permits or new technology
With the required enforcement
Pollution decreases to socially optimum, allocative efficiency
Always LR incentive to invest in LR (Profit from selling and wont be burdened when permit prices rise as gov reduces amount of permits in order to incentive green tech)

60
Q

Tradable pollution permits evaluation

A

Enforcement = expensive and resources
Imperfect info for gov = risk of gov failure
Unintended consequences = move country or close firms or higher prices for consumer
Need for international cooperation to have an effect
