Suppose there is a ten-kilometre-long two-lane highway from the suburbs to the city centre. It costs drivers twenty cents per kilometre in monetary costs plus ten cents per minute in the (opportunity) cost of their time travelling. Therefore, the total cost of the trip depends positively on the travel time. a. The number of vehicles per lane per hour (V) is the quantity and the total cost of the trip is the price. Suppose the (inverse) demand for travel is estimated to be = 34.76 0.0183 and the (inverse) supply of travel is estimated to be = 0.04 + 0.0034 . Find the competitive equilibrium price (total cost) and number of vehicles per lane per hour. (4) b. Since the more vehicles per lane per hour causes the average speed to be reduced, an additional vehicle per lane per hour not only increases the time travelled for that driver but also for all the other drivers as well. Suppose the extra time is estimated to be 0.016 additional minutes per vehicle per lane per hour. What is the cost in dollars to other drivers when an additional vehicle per lane per hour goes on the highway? Note this will be a function of the number of vehicles per lane per hour Costto other drivers(V)
