Companies considering new cost-cutting manufacturing processes often compare the projected results of making the investment against the alternative of not making the investment with costs, selling prices, and share of market remaining constant.

Which of the following, assuming that each is a realistic possibility, constitutes the most serious disadvantage for companies of using the method above for evaluating the financial benefit of new manufacturing processes?

(A) The costs of materials required by the new process might not be known with certainty.

(B) In several years interest rates might go down, reducing the interest costs of borrowing money to pay for the investment.

(C) Some cost-cutting processes might require such expensive investments that there would be no net gain for many years, until the investment was paid for by savings in the manufacturing process.

(D) Competitors that do invest in a new process might reduce their selling prices and thus take market share away from companies that do not。

(E) The period of year chosen for averaging out the cost of the investment might be somewhat longer or shorter, thus affecting the result.

1 - 17 (就是原贴中的第二题)答案是D.

这题,我也不是很明白.我从以下两个角度想可是都没想通,请教各位前辈,思路错在哪里了?

1. 题目中提到: ...with costs, selling prices, and share of market remaining constant.

那么我觉得是不是当上述三种变量发生不可控制的变化时,会对经济模型的可靠性造成影响,那么我觉得A(讲成本的不可控制)也是可以的

2. 如果纯粹从未来现金流量的经济模型来考虑这个题目,那好象A(成本), B(折现率), D(价格销售收入)和E(投资回报年数)都可以了.

彻底晕菜了!
