5. Suppose that you are the governor of Istanbul and trying to decide whether you should support the third Bosporus Bridge construction project. The project is estimated to take 5 years to complete. The project will require $50 million in construction materials per year and $20 million in labor costs per year. In addition, the project will disrupt transportation within the city for the duration of the construction. The transportation disruption lengthens transport times for 1 million workers by 20 hours a year. The project, when finished, will ease transportation within the city. Each of the 1 million workers will have their transport time reduced by 60 hours a year as compared to the pre-construction transport time for 10 years. Assume that all workers are paid $10 per hour (in other words, one hour of a worker lost/gained is worth $10), the discount rate is 5% and the benefits of the project is accrued between years 6 and 15. (a) (10 points) Show the yearly benefits and costs of this project on a table. (b) (10 points) Calculate the present value of the net benefits of this project.
