Consider a simple, homogeneous
monocentric city with a circular shape. If the
location rent premium at the center is $6,000
per year per acre, the rent at the edge of the
city is $10,000 per year per acre, and the
density is 3 persons per acre. Supposing that
the annual transportation cost per person per
mile of distance from the CBD is $200 (round-
trip), and if the population increases by 10%
(density and transportation cost do not
change), what will be the new rent at the
center of the city per year per acre?

Your boss has asked you to evaluate the economics of replacing 1,000 60-Watt incandescent light bulbs (ILBs) with
1,000 compact fluorescent lamps (CFLs) for a particular lighting application. During your investigation you discover that
13-Watt CFLs costing $2.00 each will provide the same illumination as standard 60-Watt ILBs costing $0.50 each.
Interestingly, CFLs last, on average, eight times as long as incandescent bulbs. The average life of an ILB is one year
over the anticipated usage of 1,000 hours each year. Each incandescent bulb costs $1.90 to install/replace. Installation
of a single CFL costs $2.90, and it will also be used 1,000 hours per year. Electricity costs $0.12 per kilowatt hour
(kWh), and you decide to compare the two lighting options over an 8-year study period. If the MARR is 10% per year,
compare the economics of the two alternatives and write a brief report of your findings for the boss. Assume that both
installation cost and cost of the bulbs occur at the…

The two processes have radically different cost structures. Specifically let Qool = -10 + P where Qoo is the quantity of kilowatt hours supplied by coalfired plants, and P is the price per kilowatt hour, and let Qwind =-200 +2P where Qwind IS the quantity kilowatt hours supplied by wind turbines, and Pis the price per kilowatt hour. Let demand for electricity in Minnesota, measured in kilowatt hours, be given by the equation: Qwh= 410- P. Finally, let the marginal damages (MD) imposed on the environment as a result of electricity production by coal-fired plants be equal to: MD = 0.60 Qcoal where, as before, Qcoais the quantity of kilowatt hours supplied by coalfired plants. What happens to the amount of wind energy produced and consumed in Minnesota if coal-fired plants were forced to pay for the damages they impose on the environment? a.

- Paccar Winch makes winch components for its different product lines. The firm operates its production facility three hundred and five days per year. It has orders for about twelve thousand winch components per year and has the capability of producing one hundred and five per day. Setting up the winch production costs fifty five dollars. The cost of each winch component is one dollar and ten cents. The holding cost is fifteen cents per winch component per year. a) What is the optimal size of the production run? b) What is the average holding cost per year? c) What is the average setup cost per year? d) What is the total cost per year, including the cost of the winch components?arrow_forwardThe Federal Motor Carrier Safety Administration (FMCSA) along with state transportation agencies in 41 states (as of 2012) administer interstate trucking licenses through the United States Carrier Registration Agreement. However, the registration process is complex, time consuming, and expensive. There are many fees and costly regulations that a trucker or firm must meet to operate. For example, for a large truck, the annual federal interstate registration fee can exceed $8,000. These largely lump-sum costs-which are not related to the number of miles driven-have increased substantially in recent years. Instead of being collected annually, if the lump-sum costs are collected only once (when the firm starts operation), then O A. firms would no longer produce more because the fees would be fixed costs. O B. nothing changes because the fees would still be fixed costs. O C. the market price would decrease and the market quantity would increase because the fees would be variable costs. O D.…arrow_forwardJenny Tanaka wants to buy a new car, and the annual gasoline expense is a major consideration. Her present car gets 25 miles per gallon (mpg), and she is considering purchasing a new car that gets 40 mpg. Jenny now drives about 12,000 miles per year and pays $3.25 per gallon of gasoline. She therefore calculates an annual gasoline consumption of 480 gallons for her 25 mpg car (12,000 miles/25 mpg) compared to 300 gallons consumed per year for the 40 mpg car (12,000 miles/40 mpg). Since driving the higher- mileage car would use 180 gallons less per year, Jenny estimates the new car will save her $585 in gasoline expense per year (180 gallons 3 $3.25 per gallon). Suppose Jenny buys the 40 mpg car. According to economic theory, Jenny's actual annual savings on gasoline will be 7 1 C 1 U C VI 10 V K W S TACAZEC 10 GUNS TOMBER 2 than her initial estimate of $585.arrow_forward
- Two of your classmates have an idea for a new food truck called Funk Seoul Brother, that sells Korean street food and sushi burritos. It would be the only supplier of this food in Athens. Market research suggests that the demand curve for the food will be P=40-(Q/80). It will cost $2000 to set up the food truck, which is necessary before any food can be made. In addition to the setup cost, there is a marginal cost of $6 per entrée for every entrée made. a. What is the profit-maximizing price and quantity?What profit will this food truck generate? b. If this market were instead perfectly competitive, what would be the equilibrium price and quantity? c. How much deadweight loss occurs under the monopolist?arrow_forwardA large company in the communication and publishing industry has quantified the relationship between the price of one of its products and the demand for this product as Price = 160 -0.02 × Demand for an annual printing of this particular product. The fixed costs per year (i.e., per printing) = $51,000 and the variable cost per unit = $35. What is the maximum profit that can be achieved? What is the unit price at this point of optimal demand? Demand is not expected to be more than 4,000 units per year. The maximum profit that can be achieved is $144,313. (Round to the nearest dollar.) The unit price at the point of optimal demand is $ per unit. (Round to the nearest cent.)arrow_forwardKen’s firm is committed to reducing greenhouse gas by 10 tons per year.

- There are two types of car, distinguished by how fuel eficient they are. Type O is the less fuel efficient type, and type 1 is the more fuel efficient. The inverse demand curves for the two types of car are: Po = 250 – Qo – Qı/2, P = 120 – Q1 – Qo/2. (1) Cost functions are Co(Qo) = 50Q0, C:(Q1) = 20Q1 (2)arrow_forwardThree firms in a single industry are the only source, in a given airshed, of emissions of a uniformly mixed pollutant, say, CO₂. Their emissions levels are currently e₁ = 300, e2 = 200, and e3 100, where the subscript denotes firms. The environmental regulator has decided that emissions should be reduced by half, to E=300. The firms' abatement cost functions are given by C₁ (a₁) = 0.1a₁, C₂(a₂) = 0.2a2, and C3 (a3) = 0.3a²3 respectively. (It is assumed that these functions describe the firms' entire cost structure, including the cost of producing the optimal level of output given e;.) Enforcement costs are zero and there is no uncertainty. Suppose the regulator decide to employ a Command-and-Control scheme, requiring that each firm reduce its emissions in proportion to ej. Calculate the aggregate cost of abatement and each firm's emissions level.arrow_forward(1) A company in Scotland bottles sparkling water.
