QUESTION 3
[25 Marks]
If we assume that a given bus market is in perfect competition which charges a flat fare
of £1, and if the formula for the total demand (in thousands) in the market is given by
= the equation: QD 250 - 60P
Where; QD is the quantity demanded in thousands at a given price P.
If we further assume constant returns to scale, then:
(a) What is the total market demand at the fl flat fare?
(3)
(b) If the market is shared equally by 4 firms, what is the number of passengers
carried by each company?
(2)
(c) If the cost per vehicle kilometre is £1.60, average utilisation is 20 passengers per
vehicle kilometre and average trip distance 10 kilometres:
i. What is the level of bus kilometres required to service this market? (2)
ii. What profits are being made?
(3)
iii. What type of profit is this, normal or abnormal?
(2)
iv. What is the cost per passenger carried (as opposed to the cost per
vehicle kilometre)?
(3)
(d) As this is perfect competition, new firms may enter the market and compete
these profits away. What price therefore will ensure that only normal profits are
made?
(2)
(e) At the lower flat fare, why has market efficiency now been achieved?
(3)
(f) This exercise assumes that the four firms in the market will behave consistent
with the perfect competition model, however is that in their own best interests?
What does this tell us about market structures where only a few firms exist? (5)
