Consider an urban highway that is subject to traffic congestion. The average cost of
travel per mile on that highway is (in cents):
AC= 10 + 4T,
where Tis traffic volume per hour, measured in 100s of vehicles per hour. For example,
if T = 500 cars per hour, AC = 30 cents per mile. Assume that the demand for traffic per
hour (during rush hour) is
T = 46 – P,
where P is the "price" paid by the driver.
а.
Assume that no congestion toll is imposed. Compute equilibrium T and P.
b.
Assume that it is possible to impose the efficient congestion toll. Find the toll, and
the efficient levels of T, P, and AC.
Suppose that you are in charge of a toll bridge over the Mississippi River. The demand for
bridge crossing Q is given by the following:
2P = 20 - Q
a) How many people would cross the bridge if there were no toll? (YOU MUST SHOW
YOUR WORK TO RECEIVE CREDIT)
b) The toll bridge operator is considering setting up a price of $5.00. At that price, how
many people will cross the bridge? (YOU MUST SHOW YOUR WORK TO RECEIVE
CREDIT)
c) How many people would cross the bridge if the toll is set at $10.00? (YOU MUST
SHOW YOUR WORK TO RECEIVE CREDIT)
Suppose that managers at Honda are deciding how to price the new Honda Accord. The managers estimate that their total costs
increase by $20,000 for each car they produce. They also estimate the demand curve they face; it is described by the equation:
Q = -0.4 P + 16,000,
where Q represents the quantity of Honda Accords they will sell and P represents the price they charge in US dollars.
We can re-write that demand curve as:
P = 40,000 - 2.5 Q.
Take every possibly quantity that the managers might choose between
and 7,000 in units of 100. For each possible quantity,
calculate the associated price the managers would need to charge, the revenue they would earn, and the total costs. You can then
calculate profits for each level of quantity. Highlight the cell that contains the highest value of profit.
Finally, you can also approximate marginal revenue here as the change in total revenue after the next 100 cars are produced. At what
quantity does marginal revenue roughly equal marginal cost?…

Suppose the government is considering an increase in the toll on a certain stretch of highway from $3 to $4. At present, 1 million cars per week use that highway stretch; after the toll is imposed, the number of cars per week will change according to its price elasticity of demand of -0.8 (this elasticity value is estimated based on the initial-value method). If the marginal cost of highway use is constant (i.e., the supply curve is horizontal) and equal to $3 per car, what is the net annual cost to society attributable to the increase in the toll? (your answer must be rounded off to the nearest million dollars per year, i.e., no decimal places; there are 52 weeks in a year)arrow_forwardIn the Current Events article, it mentioned how DoorDash is trying to increase its amount of subscription users (DashPass). The price for DashPass is $10 per month. Assume the demand for regular DoorDash deliveries (non-subscription) is: P = 20 - 0.04Q where P is the delivery fee on the order. Assume the goal of the company is to maximize combined revenue from both regular deliveries (delivery fees) and the subscription fees (DashPass). A different manager suggest pricing the deliveries at $14 per delivery. Which of the following actions would you select as a manager? Group of answer choices Advise that it should be a $10 fee per delivery Advise that the$14 delivery fee is too low Advise that it should be a $20 fee per delivery Agree that $14 per delivery is optimal in this situationarrow_forward
- You provide your services primarily to educational providers, helping them understand how much to charge for their schooling. Imagine that there two types of consumer – high revenue (H) and low revenue (L). Assume demand is given by PL = 1,000–QL/10 and PH = 2,500 – 2QH. In both equations, quantity is in hours of consulting provided. The marginal and average total cost of providing an hour of consulting is $50 per hour. a. Suppose you cannot see who is an H and who is a L, and you can only charge one price. What price do you charge, and how many units do you sell? b. Now imagine you can charge different prices for different quantities, e.g., quantity discounts. Propose a pricing “schedule” (that is, what prices you would offer under what quantity rules) that will allow you to earn greater profit than you would in part a. State how many hours of consulting are sold to each type of consumer.arrow_forward9. Application: Elasticity and hotel rooms The following graph input tool shows the daily demand for hotel rooms at the Big Winner Hotel and Casino in Las Vegas, Nevada. To help the hotel management better understand the market, an economist identified three primary factors that affect the demand for rooms each night. These demand factors, along with the values corresponding to the initial demand curve, are shown in the following table and alongside the graph input tool. Initial Value Demand Factor Average American household income $50,000 per year Roundtrip airfare from New York (JFK) to Las Vegas (LAS) $200 per roundtrip Room rate at the Lucky Hotel and Casino, which is near the Big Winner $250 per night Use the graph input tool to help you answer the following questions.

- Shell has over 13,000 gas stations in the United States. In addition to gasoline, the gas stations also sell convenience items, such as snacks, non-alcoholic beverages, wine, beer, and hot food. Suppose you work for a gas station and your boss asks you to develop a pricing strategy for bottled local wine. The demand function is ? = 100 – 4?, where ? is the monthly quantity demanded of the bottled wine and ? is the price of the bottled wine. The marginal cost per bottle of wine is $5. Complete the following tasks: 1) (Calculating) In the worksheet “Q2 Calculations” of the provided Excel file, enter formulas in columns B-D to calculate Q (quantity demanded), MC (marginal cost), and MR (marginal revenue). Please round your results to one decimal place. Note that the inverse demand function is ? = 25 − 0.25? and that the MR function can be derived from the inverse demand function using the formula introduced in Module 5. You may find it helpful to review the Excel file for Chapter 11.arrow_forwardThe quantity of a product demanded by consumers is a function of its price. The quantity of one product demanded may also depend on the price of other products. For example, if the only chocolate shop in town (a monopoly) sells milk and dark chocolates, the price it sets for each affects the demand of the other. The quantities demanded, q₁ and q2, of two products depend on their prices, p₁ and P₂, as follows: If one manufacturer sells both products, how should the prices be set to generate the maximum possible revenue? What is that maximum possible revenue? Enter the exact answers.
