标题[请益] 有关tax revenue
时间Mon Nov 11 15:12:24 2013
assume the price of gasoline is 2.4 per gallon and the equilibrium quantity of
gasoline is 12 million per day with no tax on gasoline . Starting from this
inotial situation,which of the following scenarios would result in the largest
deadweight loss?
A 10 percent increase in the price of gasoline reduces the quantity of gasoline
demanded by 2 percent and it increses QS by 7 percent. The tax is 0.4 per gallon
B 10 percent increase in the price of gasoline reduces QD by 1 percent and it
increases QS by 8 percent. The tax is 0.35 per gallon
我想知道是否价格与数量变化可代表整条斜率？斜率可代表某条需求县Or供给线的弹性？
而整条线的弹性可称the price elasity of demand/supply?还是要线上的点才行?

2F：推 ChrisOvO:需求或供给弹性的构成中包含斜率，但不能说斜率就是弹性 11/12 01:16
3F：→ ChrisOvO:而线上的每ㄧ点都有自己的弹性值 11/12 01:19
