The following three mutually exclusive alternative proposals are being considered for flood proofing a factory building that is located in an area subject to occasional flooding by a
nearby river.
1. Do nothing: Damage to the building in a moderate flood is $11,000 and in a severe flood it is $24,000.
2. Protect the building with a one-time initial expenditure of $20,000 so that the building can withstand moderate flooding without any damage and withstand severe flooding with
only a $10,000 damage.
3. Protect the building with a one-time initial expenditure of $32,000 so that the building can withstand any flooding with no damage at all.
In any year, there is a 19% probability of moderate flooding and a 9% probability of severe flooding. Using a MARR of 6% per year and a service life of 8 years, determine which of
the three alternatives is the most economical.

U.S. route 83 passes through the village of Burr Ridge, IL. The engineers of the Transportation Department have proposed constructing a new highway through existing farmland to bypass the city for use by through traffic. The new bypass would however entail an initial construction cost of $40 million and an average annual maintenance cost of $50,000. Assuming the overall user and non-user costs (associated with the positive and negative impacts) of the new project amount to $2 million per year, facility life of 25 years, and an annual nominal discount rate of 6% compounded quarterly, determine whether the project is worthwhile on the basis of agency costs, user costs, and non-user costs.

- A new road is being proposed to create a shortcut from a major residential area to an industrial complex 15 miles away. The current drivers with an AADT of 10,000 travel 27 miles each direction on a curvy, hilly road to the industrial park. Many do not go to the shopping center near the industrial park because of the present substandard road. The new alignment would put a new bridge over the river and cross some wetlands to shorten the distance to 16 miles. The AADT is expected to increase to 12,000. The cost of the new highway will be $80 million, including the bridge. Some rehabilitation estimated at $5 million would have to be done by the state transportation agency on the existing road in 10 years if the new road is not built. If the new road is built, the old road will be turned over to the local governments. The maintenance cost will decrease from $300,000 per mile on the old road to $250,000 per mile on the new road.

Program 1, which is expected to cost an average of $60 per household, provides a rebate of 75% of the purchase and installation costs of an ultra-low-flush toilet ($100 max). This program is projected to achieve a 5% reduction in overall household water use over a 5-year evaluation period. This will benefit the citizenry to the extent of $1.25 per household per month. Program 2 involves turf replacement with xeric (low water need) landscaping. The program is expected to cost $500 per household, but it will result in reduced water cost estimated at $8 per household per month (on the average). Use the B/C method at a discount rate of 0.5% per month to determine which program, if any, the utility should undertake.

- Five years ago a dam was constructed to impound irrigation water and to provide flood protection for the area below the dam. Last winter a 100-year flood caused extensive damage both to the dam and to the surrounding area. This was not surprising, since the dam was designed for a 50-year flood. The cost to repair the dam now will be $250,000. Damage in the valley below amounts to $750,000. If the spillway is redesigned at a cost of $250,000 and the dam is repaired for another $250,000, the dam may be expected to withstand a 100-year flood without sustaining damage. However, the storage capacity of the dam will not be increased and the probability of damage to the surrounding area below the dam will be unchanged. A second dam can be constructed up the river from the existing dam for $1 million. The capacity of the second dam would be more than adequate to provide the desired flood protection. If the second dam is built, redesign of the existing dam spillway will not be necessary, but…arrow_forwardCost of the Plan projects Cost of the Land and expropriation Cost of the Roads and preparation costs Cost of the Retaining wall Cost of the Filling and ground consolidation Cost of the Treatment facilities 520,000 TL 1,680,000 TL 1,300,000 TL 15,800,000 TL 3,650,000 TL 10,900,000 TL 17,500,000 TL Cost of the 70 km 1.25 m diameter transmission line Annual repair-maintenance costs are increased by 1,250,000 TL in the first year and by 6% every year.

Sandra has a dog that she walks every day. Sandra has to walk past Mary's front lawn and her dog always pees on Mary's flowers, which causes them to eventually die. Mary will move in a few months but, until then, she estimates she will spend $100 on flowers to replace the ones that die as a result of the daily visits from Sandra's dog. The only solution to this problem is a $50 fence that can be put around Mary's flowers that will protect them from Sandra's dog. a. What term do economists use for the consequences of Sandra's daily walks in this setting? b. Is it socially optimal to have the fence put around the flowers in this case? Why or why not? c. What does the Coase theorem say about how the social optimum could be achieved? Explain what an agreement between Sandra and Mary would look like if Mary has the right to not be bothered by her neighbour's dog.arrow_forward
- The state of Glottamora has $300 million remaining in its budget for the current year. One alternative is to give Glottamorans a one-time tax rebate. Alternatively, two proposals have been made for state expenditures of these funds. The first proposed project is to invest in a new power plant, costing $300 million and having an expected useful life of 20 years. Projected benefits of the new power plant are as follows: Years Benefits per Year ($ Millions) 1 - 5 0 6 - 20 60 The second alternative is to undertake a job retraining program, also costing $100 million and generating the following benefits: Years Benefits per Year ($ Millions) 1 - 5 60 6 - 10 42 11 - 20 12 The state Power Department argues that a 5 percent discount factor should be used in evaluating the projects because that is the government’s borrowing rate.

The fixed cost to produce the doll is $100,000. The variable cost, which includes material, labor, and shipping costs, is $34 per doll. During the holiday selling season, FTC will sell the dolls for $42 each. If FTC overproduces the dolls, the excess dolls will be sold in January through a distributor who has agreed to pay FTC $10 per doll. Demand for new toys during the holiday selling season is extremely uncertain. Forecasts are for expected sales of 60,000 dolls with a standard deviation of 15,000. The normal probability distribution is assumed to be a good description of the demand. FTC has tentatively decided to produce 60,000 units (the same as average demand), but it wants to conduct an analysis regarding this production quantity before finalizing the decision.
