Focus on the difference between feasible alternatives. Insulated concrete forms (ICF) can be used as a substitute for conventional wood framing in building construction. Heating and cooling bills will be about 50% less than in a similar wood-framed building in upstate New York. An ICF home will be approximately 10% more expensive to construct than a wood-framed home. For a typical 2,000 ft2 home costing $120 per ft2 to construct in upstate New York and costing $200 per month to heat and cool, how many months does it take for a 2,000 ft2 ICF home to pay back its extraconstruction cost?

- EXAMPLE 11-2 Two Alternative Breakeven Analysis: Hybrid Vehicles Gas-electric (so-called hybrid) vehicles save on gasoline consumption by shutting off the vehicle's engine while idling, giving the vehicle a boost of electric power during acceleration, and capturing electrical energy while braking. In addition to environmental benefits, the primary monetary benefit to the owner is reduced fuel cost as a result of improved gas mileage. The trade-off, however, is that the purchase price of the hybrid vehicle is higher than that of a standard gasoline-only fueled vehicle. Consider a hybrid vehicle with a sticker price of $31,500. This vehicle will average 30 miles per gallon of gasoline. A tax credit of $1,500 for the hybrid vehicle effectively reduces its sticker price to $30,000. A comparably equipped gasoline-only vehicle will cost $28,000 and will average 25 miles per gallon of gasoline. Assuming an interest rate of 3% per year and a study period of five years, find the breakeven cost…arrow_forwardSandra and Mary live next to each other. 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_forwardThe sheriff of Los Lunas county along the Arizona- Mexico border asked the county to build a new minimum security detention facility for personscaught while attempting to enter the United States illegally. The construction cost will be $22 million, with annual operating costs of $2.1 million. The new facility will create jobs that produce benefits for many local businesses including realtors, restaurants, etc. The benefits are estimated to be $5 million in years 1 and 2, $2.8 million in year 3, and $1.12 million per year beginning in year 4 and continuing through the 30-year life of the facility. At a discount rate of 8% per year, does the conventional B/C ratio indicate that the project is economically justified?arrow_forward
- In the design of a jet engine part, the designer has a choice of specifying either an aluminum alloy casting or steel casting. Either material will provide equal service, but the aluminum casting will weigh 1.2 kg compared with 1.35 kg for the steel casting. The aluminum can be cast for $ 80.00 per kg and the steel one for $35.00 per kg. The cost of machining per unit is $ 150.00 for aluminum and $ 170.00 for steel. Every kilogram of excess weight is associated with a penalty of $ 1,300 due to increased fuel consumption.
