Define (a) externalities and (b) sunk costs, andthen give examples of each that might be involvedin a proposal by an energy company to build anew coal-fired electric power generating unit. Howwould these factors be worked into the analysis?

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…
