in process product不计入GDP？ 前面视频不是说中间商品不计入GDP吗，所以这里的Add-valued不属于中间商品 而是附加值 属于计算GDP的其中一种是吧

能不能详细说一下呢？

第十四题怎么写

第四题怎么写

根据利率期限结构理论，利率曲线呈下降趋势，表面短期利率水平大于长期预期利率水平，那么请老师解释一下A、C错在哪里？

55 The Industry and Business Risk excerpt states that, “Increased competition may lead to lower unit sales and excess production capacity and excess inventory. is may result in a further downward price pressure.” The downward price pressure could lead to inventory that is valued above current market prices or net realisable value. Any write-downs of inventory are least likely to have a significant effect on the inventory valued using: A weighted average cost. B first- in, first-out (FIFO). C last-in, first-out (LIFO). 这一题不懂，1）B选项当价格下降的时候，FIFO下最不可能减值是因为FIFO下ending inventory反映的是最新的存货价格，所以不容易减值吗？2）原版书答案后半段是什么意思，为什么又说通常LIFO下不容易减值，是因为通常情况下存货成本是上升的吗？3）题目中说的downward price pressure是产品的价格还是存货的价格是下降的？

这个第七题不太理解。请老师讲解一下逻辑

total factor productivity在GDP的恒等式里指的是哪一部分？为什么不能被直接计量？

54 Note 2 indicates that, “Inventories valued on the LIFO basis totaled¥94,578 million and ¥50,037 million at December 31, 2017 and 2018, respec-tively.” Based on this, the LIFO reserve should most likely:A increase.B decrease.C remain the same.为什么LIFO下存货下降说明LIFO reserve下降？

第一行是截距B0 第二行不是自变量x吗？还是默认是斜率？
