The government is considering a congestion charging scheme in Manchester, UK. The scheme will cost and initial 52 million to implement (consider this year 0), and a further 16m in year 1, in order to ensure efficiency (including maintenance). The scheme will yield estimated benefits (through charging car users 5 for entry/exit into Manchester) of 30m in year 1, 28m in year 2, and 20m in year 3. The expected rate of interest (discount) is 5%. Discount these figures to present value, and perform a cost benefit analysis on the scheme. Should the scheme go ahead? (15 marks)
