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
我想知道是否價格與數量變化可代表整條斜率？斜率可代表某條需求縣Or供給線的彈性？
而整條線的彈性可稱the price elasity of demand/supply?還是要線上的點才行?

2F：推 ChrisOvO:需求或供給彈性的構成中包含斜率，但不能說斜率就是彈性 11/12 01:16
3F：→ ChrisOvO:而線上的每ㄧ點都有自己的彈性值 11/12 01:19
