Answer any five (5) of the following questions.
Each question is worth 10 marks.
Question 1:
(a) Suppose that oil prices rise sharply for years as a result of a war in the Middle East.
Illustrate witha diagram what happens to the:
(i)Demand for automobiles?
(ii)Demand for home insulation?
(iii) Demand for coal?
(iv) Demand for tyres?
(v) Demand for bicycles?
(b) Explain the impact of external costs and external benefits on resource allocation; (2.5 marks)
(c) Why are public goods not produced in sufficient quantities by private markets? (2.5 marks
Question 2:

(b) Suppose a chocolate bar manufacturer promotes its products by advertising and opportunity to win a 'free car'. Is this car free
because the winner pays zero for it? Illustrate and explain using a diagram. (2.5 marks)
(c) Why is the production possibility frontier bowed outwards? (2.5 marks)
Question 3:
In some large cities, motorists pay a fee when they bring their vehicles into the busiest part of the city (congestion charge).
(a)Illustrate with a diagram and explain how this charge is an example of the price system at work; (2.5 marks for diagram plus 2.5 marks for explanation)
(b) How do you think that the authorities would determine the level of the charge if they have a particular target for the reduction in the number of vehicles entering the congestion charge zone? (2 marks)
(c) Given that revenues from these congestion charges are invested in the city's transport system, how will this affect the charge level holding all other variables constant? (3 marks)
Question 4:(a)Suppose the income elasticity of demand for pre-recorded music compact disks is +7 and the income elasticity of demand for a cabinet maker's work is +0.7.
Compare the impact on pre-recorded music compact disks and the cabinet maker's work of a recession that reduces
consumer incomes by 10 per cent. (2 marks)Please check the attachment and answer all the seven questions mentioned in attached file.
