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！
