Q

evaluate restrictions/laws as a method to reduce NCE

A

cons:
- unemployment might increase in the specific sector
- loss of government revenues from taxes
- smokers in the SR will be worse-off as they will enjoy less of the good
- need to monitor that laws are followed or else they will be broken
pros:
- but in the LR they will be better-off if their health improves
- non-smokers will be better off as the externality will decrease

Q

evaluate indirect taxes as a method to reduce NCEs

A
  • tax is regressive so poorer groups are worse-off
  • Qd will not fall significantly if PED is inelastic
  • difficult to accurately measure externality and thus correct it (you might over or under shoot). So difficult to set the tax at the right level to internalise the external costs.

Q

congestion charge as an eg of decreasing NCEs

A

the effectiveness depends on how close or weak substitutes drivers think cars and public transportation are. Public transportation is usually less comfortable and takes longer

(-) Domestic businesses might see a decrease in their customers if it is harder for them to access the city centre and there are no other substitutes. Consumers might switch to online shopping.
(-) higher income groups will not be significantly affected as it is a small percentage of their income
(+) part of the externality is internalised

  • subsidies
  • legislation/regulation
  • positive advertising

elsewhere

31
Q

give 3 ways in which negative production externalities can be reduced

A
  • legislation & regulation
  • carbon taxes
  • tradable pollution permits
32
Q

explain legislation and regulation as a method of reducing NPEs

A

supply decreases; MPC decreases and shifts to the left

33
Q

define MPC

A

marginal private cost; the change in the producer’s total cost brought about by the production of an additional unit of a good or service.

34
Q

evaluate legislation and regulation as a method of reducing NPEs

A

pros:
- cost of production might increase if firms need to pay to have their waste burnt or if they need to buy filters -> maybe higher prices for consumers
- less pollution -> sustainable growth

cons:
- need to monitor that laws are followed or else they will be broken
- high administrative costs to regulate all industries
- fines should be high in order to deter firms from breaking the law
- higher unemployment in specific industries
- firms might relocate to countries with more relaxed laws
- Regulatory capture

35
Q

explain carbon taxes as a method of reducing NPEs

A

cost of production increases -> supply decreases; MPC decreases and shifts to the left

36
Q

evaluate carbon taxes as a method of reducing NPEs

A
  • cost of production will increase -> maybe higher prices for consumers
  • producers might switch to “green” technologies in order to avoid carbon taxes
  • less pollution -> sustainable growth
  • more government revenues
  • domestic firms might shut down if consumers import from abroad from countries with weaker environmental regulations
  • difficult to accurately measure externality so usually tax doesn’t equal the externality (over or under shoot). If tax equaled externality then it would be internalised.
  • higher unemployment in specific industries
  • externality is internalised
37
Q

is internalising an externality a good or bad thing?

A

Internalising externalities helps to create a more efficient and equitable allocation of resources by ensuring that the costs and benefits of economic activities are reflected in the prices paid by the participants, rather than being imposed on third parties.

38
Q

explain tradable permits/cap and trade scheme as a method of reducing NPEs

A

supply falls; MPC decreases and shifts left

39
Q

evaluate tradable permits/cap and trade scheme as a method of reducing NPEs

A
  • cost of production will increase -> maybe higher prices for consumers
  • difficult to set acceptable pollution level & measure how much each firm is polluting
  • less pollution -> sustainable growth
  • need to monitor that laws are followed or else they will be broken
  • higher unemployment in specific industries
  • externality is internalised
  • Firms may relocate to other countries with more relaxed laws
  • administrative costs to the government
40
Q

give an example of tradable permits

A

EU Emissions Trading System (ETS)
- The permits for greenhouse gas emissions are distributed between the EU member countries
- Then each EU country distributes the permits to the firms
- Firms can trade permits. If they exceed their allowance then they will be fined if they are caught
- In order to help reduce pollution, each year the number of permits decreases in order for firms to strive to lower their emissions

41
Q

draw a diagram for the EU trading system

A

elsewhere

42
Q

ETS Main Disadvantage

A

The price per permit is very low because initially the EU issued many permits

43
Q

state 2 policies to address pollution

A

subsidise cleaner firms and international agreements

44
Q

why are international agreements required?

A

pollution is a global problem

45
Q

explain how subsidising green firms helps reduce pollution

A

cost of production decreases-> supply increases for “greener” firms

46
Q

evaluate subsidising green firms as a way to reduce pollution

A
  • cost to the government
  • subsidies should be given to such an extent that it is cheaper for the firms to use cleaner energy (e.g. solar power) instead of buying fossil fuels (substitutes)
  • fossil fuel producers will be worse off but renewable energy producers will be better off
  • less pollution -> sustainable growth
  • higher unemployment in specific industries
  • renewable energy (e.g. wind farms) may create visual and noise pollution and decrease property prices
47
Q

give an example of international agreements as a way to help reduce pollution

A

e.g. KYOTO protocol (goal: reduce greenhouse gases), Paris agreement and SDGs

48
Q

give 4 problems of using fossil fuels as energy sources

A

Demand for fossil fuels has increased (depleted)
When fossil fuels are burned, GHG are emitted into the atmosphere (a CAR) -> climate change: floods, extreme weather
Furthermore, sometimes when they are extracted oil spills occur which damage the area, the local communities and lead to many animals dying.
Their extraction & use generate external costs that threaten the future generations’ access to them (Negative production externalities)

49
Q

how is sustainability threatened by LDCs?

A

LDCs rely primarily on agricultural goods or commodities for income-> pressure on land resources for subsistence purposes and for more intensive cultivation to support their livelihood-> deforestation and soil erosion

50
Q

how do more developed countries exacerbate LDCs’ threat to sustainability?

A

LDCs often have debts
They are pressured by the IMF or the World Bank to increase export revenue and facilitate foreign direct investment (FDI) to repay their debts
Result: pollution and depletion of natural resources -> unsustainable growth in LDCs

51
Q

give 2 characteristics of common access resources

A

Non-excludable- everyone can use it
Rivalrous- when one person uses it, this diminishes the utility for someone else

52
Q

what is the problem with CARs?

A

over-used -> depleted-> Threat to sustainability:
Tragedy of the commons- Individuals benefit from exploiting the resource but the cost of exploitation is shared amongst everyone

53
Q

define sustainable development

A

Sustainable development is the development that meets present needs without compromising the ability of future generations to meet their own needs.

54
Q

give 6 examples of CARs

A

Common fishing grounds
Sheep grazing a pasture
Black rhinos
Forests
Oceans
Atmosphere

55
Q

give 4 reasons why CARs are exploited

A

lack of price
lack of ownership
high poverty & pursuit of economic growth (mainly LDCs)
lack of regulations

56
Q

6 ways in which governments try reduce exploitation of common access resources

A

Legislation (e.g. fishing seasons)
Tradable Permits (e.g. 10 fish/day)
- The EU fish quotas might be set at a high level because depletion of fish stocks continues
- Fishing boats throw back smaller dead fish in order to catch bigger ones and meet their quota
Fence areas (conservation areas)
Assign property rights
Privatize communal areas
Education

57
Q

evaluate assigning property rights as a way to try and reduce exploitation of common access resources

A

(+) The negative externalities created can now be accounted for (e.g. individuals with property rights over a lake can sue companies that pollute the river)

(-) Individuals may not sue companies as it is very expensive and may take many years

(-) It may be difficult to determine the polluter in some cases (e.g. if a river is very long and there are many firms set near that river- Thames)

58
Q

give the main strengths and limitations of govt policies to correct externalities and approaches to managing common pool resources

A
  • challenges involved in the measurement of externalities
  • degree of effectiveness
  • consequences for stakeholders
59
Q

pros and cons of international cooperation

A
  • global nature of sustainability issues
  • challenges faced in international cooperation
  • monitoring and enforcement
60
Q

Define positive production externalities

A

When the production of a good or service benefits a third party and the third party doesn’t pay for it

61
Q

give an example of a positive production externality

A

firms producing using green technology and less harm to the environment, thus sustainable growth

62
Q

draw a diagram for a positive production externality

A

underproduction of merit good as MPC, S < MSC

63
Q

give 3 ways that govt could increase positive production externalities

A

Laws & fines (ie making it mandatory to do something)
subsidies (increase supply)
taxes (increase supply)

64
Q

pros and cons of laws & fines as a way to increase positive production externalities

A

(-) cost of production might increase-> maybe higher prices for consumers (poorer consumers will be severely affected if the price of necessities increases)

eg for greener production technologies:
(+) less pollution -> sustainable growth

(-) need to monitor that laws are followed or else they will be broken

(-) fines should be high in order to make the firms adhere to the laws

65
Q

pros and cons of subsidies as a way to increase positive production externalities

A

(-) higher cost to the government ->maybe higher future taxes

(-) opportunity cost -> less spending on other areas

eg (+) less pollution -> sustainable growth (in this case)

(-) difficult to accurately measure externality so usually subsidy doesn’t equal the externality (over or under shoot).

(-) higher unemployment in industries that aren’t subsidised

eg (-) subsidies should be given to such an extent that it is cheaper for the firms to use cleaner energy (e.g. solar power) instead of buying fossil fuels (substitutes)

66
Q

pros and cons of taxes as a way to increase positive production externalities

A

(-) less tax revenues to the government

eg (+) less pollution -> sustainable growth (in this case)

(-) difficult to accurately measure externality so usually subsidy doesn’t equal the externality (over or under shoot).

(-) higher unemployment in industries that don’t use that technology

67
Q

Define a public good

A

goods that are non-excludable and non-rivalrous

68
Q

Why would public goods not be provided at all in a free market?

A

Due to the free rider problem- This occurs when people can benefit from a good/service without paying anything towards it.

69
Q

what does non-excludable mean?

A

it is costly or impossible for one user to exclude others from using a good
when one person uses it, this diminishes the utility for someone else

70
Q

3 types of goods:
- pure public
- quasi public
- private

A
  • Pure public goods: goods that are non-excludable and non-rivalrous
  • Quasi public goods: goods that are either non-excludable or non-rivalrous (e.g. roads with tolls)
  • Private goods: goods that are excludable and rivalrous (e.g. diet coke)
71
Q

Policies to overcome the lack of public goods in the free market

A

direct govt provision or public-private partnerships
