Textbook Question
Chapter 14, Problem 14P
The additive weighting model is a decision tool that aggregates information from different independent criteria to arrive at an overall score for each course of action being evaluated. The alternative with the highest score is preferred.
The general form of the model is
where
Vj = the score of the jth alternative;
ωi = the weight assigned to the ith decision attribute (1 ≤ i ≤ n);
xij = the rating assigned to the ith attribute, which reflects the performance of alternative j relative to maximum attainment of the attribute.
Consider Table P14-14 (p. 597) in view of these definitions and determine the value of each “?” shown. (14.7)

- Don't used Ai solutionarrow_forward"Whether the regulator sells or gives away tradeable emission permits free of charge, the quantities of emissions produced by firms are the same." Assume that there are n identical profit-maximising firms where profit for each firm is given by π(e) with л'(e) > 0; π"(e) < 0 and e denotes emissions. Individual emissions summed over all firms gives E which generates environmental damages D(E). Show that the regulator achieves the optimal level of total pollution through a tradeable emission permit scheme, where the permits are distributed according to the following cases: Case (i) the firm purchases all permits; Case (ii) the firm receives all permits free; and Page 3 of 5 ES30031 Case (iii) the firm purchases a portion of its permits and receives the remainder free of charge.arrow_forwardcompare and/or contrast the two plays we've been reading, Antigone and A Doll's House.arrow_forward
- Please answer step by steparrow_forwardSuppose there are two firms 1 and 2, whose abatement costs are given by c₁ (e₁) and C2 (е2), where e denotes emissions and subscripts denote the firm. We assume that c{(e) 0 for i = 1,2 and for any level of emission e we have c₁'(e) # c₂' (e). Furthermore, assume the two firms make different contributions towards pollution concentration in a nearby river captured by the transfer coefficients ε₁ and 2 such that for any level of emission e we have C₂'(e) # The regulator does not know the resulting C₁'(e) Τι environmental damages. Using an analytical approach explain carefully how the regulator may limit the concentration of pollution using (i) a Pigouvian tax scheme and (ii) uniform emissions standards. Discuss the cost-effectiveness of both approaches to control pollution.arrow_forwardBill’s father read that each year a car’s value declines by 10%. He also read that a new car’s value declines by 12% as it is driven off the dealer’s lot. Maintenance costs and the costs of “car problems” are only $200 per year during the 2-year warranty period. Then they jump to $750 per year, with an annual increase of $500 per year.Bill’s dad wants to keep his annual cost of car ownership low. The car he prefers cost $30,000 new, and he uses an interest rate of 8%. For this car, the new vehicle warranty is transferrable.(a) If he buys the car new, what is the minimum cost life? What is the minimum EUAC?(b) If he buys the car after it is 2 years old, what is the minimum cost life? What is the minimum EUAC?(c) If he buys the car after it is 4 years old, what is the minimum cost life? What is the minimum EUAC?(d) If he buys the car after it is 6 years old, what is the minimum cost life? What is the minimum EUAC?(e) What strategy do you recommend? Why?

The corporation is a profitable one that has a 22% combined incremental tax rate. At the end of 5 years the mining company changed its method of operation and sold the production machinery for $40,000. During the 5 years the machinery was used, it reduced mine operation costs by $32,000 a year before taxes. If the company MARR is 12% after taxes, was the investment in the machinery a satisfactory one? Please show every step with formulas and don't use excel. The answer should be 14.8%, thank you.arrow_forward
