Suppose 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

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.
Bill’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.

- An engineer is working on the layout of a new research and experimentation facility. Two operators will be required. If, however, an additional $100,000 of instrumentation and remote controls were added, the plant could be run by a single operator. The total before-tax cost of each plant operator is projected at $35,000 per year. The instrumentation and controls will be depreciated by means of a modified accelerated cost recovery system (MACRS). If this corporation (22% combined corporate tax rate) invests in the additional instrumentation and controls. how long will it take for the after-tax benefits to equal the $100,000 cost? In other words, what is the after-tax payback period? Please write out every step and formula, don't use excel. The answer should be 3.08 years, thank you.arrow_forwardThe effective combined tax rate in a firm is 28%. An outlay of $2 million for certain new assets is under consideration. Over the next 9 years, these assets will be responsible for annual receipts of $650,000 and annual disbursements (other than for income tax) of $225,000. After this time, they will be used only for stand-by purposes with no future excess of receipts over disbursements. (a) What is the prospective rate of return before income taxes? (b)What is the prospective rate of return after taxes if straight-line depreciation can be used to write off these assets for tax purposes in 9 years?

Once recovered, an individual cannot be re-infected and remains immune for life. The transmission rate, t, is 1/20. The recovery rate, k, is 1/5. Each person interacts randomly with others in the population and has contacts with 10 people each time period. There is no birth or death in the population. -Initially all people are susceptible. - No one dies from the disease and there is no treatment. a) Draw a compartmental model for this infectious disease.arrow_forward
