Question

微观经济学英文分析，解答一下，谢谢．

Exercise 1
The price-quantity data in the following table will graph a straight line demand curve. Use both the
elasticity measure and the total revenue curve to determine the elasticity of demand for each price
change. What can you conclude about the relationship between the slope of the demand curve and its
elasticity ? Answer the question using both numerical and graphical methods.
Product Price ($) Quantity Demanded Total Revenue($)
7 0
6 1
5 2
4 3
3 4
2 5
1 6

Answer 1

mpb（marginal
private
benefit）
边际个人收益
meb（marginal
external
benefit）
边际内部收益
msb（marginal
social
benefit）
边际社会收益
msb=mpb+meb
可以用税收政策给予改善。c&rqmsc=mpcd=mpbmsb征税
tec=技术
mec(
marginal
external
cost)
边际内部成本
msc=marginal
social
cost
边际社会成本

Answer 2

练习 1
The price-quantity data in the following table will graph a straight line demand curve. 下面数据表上的“价格—数量”数据会显示一条呈直线的需求曲线。
Use both the elasticity measure and the total revenue curve to determine the elasticity of demand for each price change.用弹性测量和总收入曲线来决定每个价格变化的需求弹性。 What can you conclude about the relationship between the slope of the demand curve and its elasticity ? 你能从需求斜率和弹性之间总结出什么关系？同时用数据和图标答题。
Product Price 产品价格($) Quantity Demanded 需求量Total Revenue 总收入($)

Answer 3

练习1
下列曲线图反映了需求与价格的关系。使用弹性测量和总收入曲线来决定每一种价格变化的需求弹性。您能从需求曲线的斜率和它的弹性中间发现什么关系？使用数字与图标的形式来回答该问题。产品价格 ($) 数量需求 总收入($)
