Suppose the City of Oolagah is considering building a new water treatment facility to better address nutrient pollution from agricultural runoff. The plant will cost the city $4 million and take one year to build, after which point it will generate $375,000 per year in health benefits over a 20 year time horizon. a)The city has a discount rate of 6%. Please neatly fill in the table below. Time Benefits Costs Net Benefits Present Value of Net Benefits 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 b)What is the Net Present Value of this proposed project? If efficiency was the only objective for making the decision and we have fully accounted for all costs and benefits would you recommend the project go ahead or not? c) Now suppose that the new plan would only generate health benefits for 17 years. What is the NPV of this proposed project? If efficiency was the only objective for making the decision and we have fully accounted for all costs and benefits would you recommend the…

Suppose we are interested in reducing the carbon footprint associated with heating/cooling buildings oncampus. The functions below describe marginal costs ofCO2abatement (expressed as a function of pollution)for two buildings on the Hendrix College campus. These are hypothetical but are influenced by buildingcharacteristics like age, size, and types of usage. (This information is used for questions 1-4) MCMills = 100−10xM MCSLTC = 75−2.5xS 1. If the College pursued its abatement target by directing each building manager to cut emissions in halffor their respective building, what is the total cost of abatement? 2. If the abatement were pursued with an on-campus carbon tax of$30, would there be the same level ofabatement? Show your work and/or explain. 3. If the goal of the college is to meet the abatement target from question 1, what is the appropriate taxrate? 4. If the appropriate tax rate is used (answer from Q3), how much money can be saved compared to thecommand & control…

Ella lives in Flint Michigan where the city water was contaminated with harmful chemicals and lead. Ella’s infant now suffers from mental retardation due to lead poisoning. This is an example of Group of answer choices social cost for Ella and her family because they bear some cost derived from the water distribution activity. private cost for Ella and her family because they do pay for the water they receive from the city of Flint. external cost for Ella and her family because they bear some cost derived from the water distribution activity.
