OG11补充材料第4题,是不是涉及到金融啊

4,the price the government pays for standard weapons purchased from military contractors is determined by a pricing method called "historical costing ."hostorical costing allows contractors to protect their profits by adding a percentage increase ,based on the current rate of inflation ,to the previous year's contractual price .

which of the following statements ,if ture ,is the best basis for a criticism of historical costing as an economically sound pricing method for military contracts ?

a)the government might continue to pay for past inefficient use of funds .

b)the rate of inflation has varied considerably over the past twenty years .

c)the contractual price will be greatly affected by the cost of materials used for the products .

d)many taxpayers question the amount of money the government spends on military contracts .

e)the pricing method based on the historical costing might not encourage the development of innovative weapons .

答案是A,OG 上解释是if the original contract price accommodated the contractors' inefficients , the government 's overpayments for these inefficiencies are simply perpetuated .我不明白这里的INEFFICIENT与PRICE , INFLATION 都有什么关系?为什么解释C的时候说identifying the importance of the cost of material ,which also varies with inflation , is a strength of the method .请问COST 和INFLATION 有什么关系?? 这是不是涉及到金融的知识,还是我不知道的一般常识??

再问, 我现在做的是OG11紫色的补充材料, 看大家在公布的一些资料和讨论怎么没有涉及到这本书的? 是排序不一样吗? 旧版的OG 是不是就是OG11及补充材料的综合??

希望大家能给我指点, 万分感激!

这题无需金融知识也能做的出

题目告诉我们什么是historical costing ，就是在去年的价钱的基础上加上一定比例的提升。这种提升的依据是通货膨胀的因素。至于通货膨胀怎么影响了制造商使得他们要提价我们不需要知道，只需知道这是个提价的理由即可。

所以现在的价格就是＝去年的价格+提升的百分比（有理由）。

问的是weaken

A说的比较婉转，对于去年的钱，有一部分钱是没有充分使用的，但是呢，基于上述的“只加不减”的定价系统呢，这样的钱将会再被支付一次，这样的话，显然这个支付系统相当的不合理。
