生产率增加不也能导致产能增加么！那么雇佣率不一定就增加啊！？

In the short run, an increase in output at low levels of production will most likely cause: A an increase in the marginal cost due to the rising total fixed cost. B an increase in the marginal cost due to the law of diminishing returns. C a decrease in the marginal cost due to economies from greater specialization.

Given the following condition: the inventory—sales ratio has risen, unit labor cost is stable, and real personal income has decreased, it is most likely that a peak in the business cycle: A Has occurred. B Will occur sometime into the future. C Is just about to occur.

这题如果当做计算器计算IRR应该怎么计算？ 可不可以这样认为？初始投资100元，第一年分红10元，第二年分红4.4元(110*1.04-110),第三年收回97.712元(100-114.4*0.02) 但是这样用计算器算出的IRR为4.21， TWRR=(1.1*1.04*0.98)^(1/3)=3.88% 这样的话TWRR<MWRR 帮忙看看哪里有问题？谢谢！

请问这道题PMT在年初 计算器上怎么按呀

老师，这道题是否可以理解为“一国可直接控制的是其进口，但进口因为非弹性而无法调整量，而出口量不受一国直接控制，因为不能强卖，所以进出口比例无法由该国控制，只能依靠外国对本国出口商品的价格弹性”？

money supply下降，紧缩货币政策，削减需求，AD下降。

这道题的数字满迷惑的，其实是两部分费用，一部分是重组费用20m，一部分是减值费用15m，也就是20x7的EBT是少35，对吗？而不是说20分成了5和15。。。虽然不影响最后解题，但这里英文and连接得好迷，读了好久好久。。。

老师你好，讲义视频中说使用FIFO,COGS 低 但是inventory ending 是高的。这道题为什么inventory 也是低呢？

Given that nominal spot exchange rate(USD/HKD) increase by 8.5%, the Hong Kong price level decreased by 5%, and the US price level increases by 3.5%, then the change in the real exchange rate(%) is closest to: A 14.8%. B –0.41%. C 0.7%. 上一题 这个题需要详细讲下，讲义上没听懂
