- B

- D
D the elasticity of supply of the good
- A
5Negative externalities exist in a market for a good giving rise to a misallocation of resources.
This misallocation is most likely to have resulted from- AA the product being over-priced.
- B
B over-production of the product. - C

- D
D too few resources devoted to producing the product
- AA the product being over-priced.

9The price mechanism helps to allocate resources efficiently because

output they produce increases. - B
B it will lead to a distribution of output amongst individuals on the basis of greatest need.
- C

has estimated their price elasticity of demand is -2.0?- AA 17.5

15‘Electricity suppliers are required to buy a growing amount of electricity from renewable
energy generators. By 2010, this must amount to at least 10 per cent of total electricity bought
from all generators. Green energy generators are paid more for their electricity because there is
a scarcity of supply of electricity generated from renewable resources.’

- B
B the social cost of electricity generated from renewable resources is greater than the
private cost. - C
C the government is subsidising the negative externalities arising from the production of
‘green energy’. - D
D electricity suppliers are paying higher average prices for their electricity because some
of the electricity is generated from ‘green sources’.
- AA the government is subsidising the production of renewable energy.
16One reason why specialisation raises labour productivity is because
- AA specialisation shifts the production possibility boundary to the left.
- B
B labour replaces capital to produce goods and services. - C
C specialisation requires an economy to produce on its production possibility boundary.
- D
D the division of labour makes it cost-effective to provide workers with specialist
equipment.

C a rise in the quantity supplied of one product reduces the supply of the other product.
- D
D a fall in the price of one product reduces the cost of supplying the other product.

B the amount consumers spend on the product will increase.
- C
C the quantity demanded will increase by 75%. - D
D the amount consumers spend on the product will fall.

- D
D consumer satisfaction is maximised
- AA there is maximum output at minimum cost.
21ëAccording to the Environment Secretary, the country has to ìface up to the need to make
some difficult choicesî on reducing its growing mountain of waste. Household waste is
growing at about 3% a year, creating a need for a doubling of waste disposal capacity by
2020. But landfill and incineration are unpopular, while the introduction of recycling and
composting has been hampered by a lack of demand for recycled materials.í
It can be inferred from the data that- AA the opportunity cost of landfill is incineration.
- B
B greater composting of waste would reduce the annual rate of growth of waste.
- C
C the private cost of waste disposal is greater than the social cost. - D
D prices for recycled materials are low.
- AA the opportunity cost of landfill is incineration.
