Assume that incidental management cost are $3 per acre per year.Quali Assume that incidental management cost are $3 per acre per year.Quali hunters will pay$5.35 per acre per year for hunting rights for plantation five years old or less. At age 17,a selection thinning can generate$335 per acre.In year 34,clear-cutting the tract can generate $2765/acre.If your discount rate is 4%,then what is the B/C ratio?In addition,if this is the optimalmanagement regimem then what is the soil expectation velue based on this management? 7.<Benefit/Cost ratio for road development>Suppose your company is studying a potential contract with the federal government to construct a 3-mile road prior to harvesting the public timber,If calculating the benefit/cost ratio is your companny's primary tool for evaluating any contract,then what is the ratio if expected present value of timber revenues is $7000000 and the road building costs are $1000000 per mile? What does the ratio tell you? Is the activity feasible? What if the expected yield from the future timber harvest were only $2500000 due to major errors in the precontract inventory? What does your benefit/cost ratio say? How does it compare to the first scenario? 8.<Terminating periodic net revenues>Suppose you need to evaluate the cash flow derived for a terminating periodic net revenue stream that ends in 20 years and a perpetual periodic net revenue stream.If you were evaluating these two net revenue streams on a present value basis, then what would you expect the relative value to be? In other words,would you expect them to ne the same? Why or Why not? Assume periodic net revenue of $500 that occurs every five years and a real risk-free alternative rate of returen is 4.5%. After evaluating the results for the two revenue streame do you get the relationship you expected from answeing the first question? What happens if you add a 3% risk factor to your alternative rate of return? Do you get the same results? What happens to the magnitude of your results? 9.P22~23 问题2.7 10.P62~63 问题4.5 11.名词解释 每题3分 共30分 ˙Non-timber Forest Products ˙Diameter Distribution of Trees ˙Mean Annual Increment ˙Internal Rate of Return ˙Soil Expectation Value ˙Scenic beauty index ˙Habitat suitability index ˙Site Index ˙Objective function ˙Shadow price --
