標題[作業] 總需求和總供給曲線求方程式
時間Thu Apr 29 22:08:33 2010
Consider an economy characterized by the following relationships :
Consumption C=20+0.8(Y-T)
Investment I=620-4000r
Government Expenditure G=400
Taxes T=0.25Y-100
Money Demand Md=P(25+0.2Y-1000r)
Money Supply Ms=345
Nominal Wage W=10
Production Function Y=200N^1/2
(1) Derive the IS and LM equations and demonstrate that each has the “proper
” slope.
(2) Derive the aggregate demand equation and demonstrate that it has the ‘
proper” slope.
(3) Derive the aggregate supply equation and demonstrate that it has the ‘
proper” slope.
我主要是問2和3 is和lm的曲線就由g+i=s+t和money demand=money supply求就可以了
那as和ad呢 我記得這兩條線都是由畫圖找出來的
可是方程式要怎麼寫呢

2F：→ celestialgod:你可以記b信給我 加我msn 我教你寫= = 04/30 00:21
3F：推 rekp:這題是89年成大企管，AD是維持商品市場與貨幣市場同時達到 04/30 00:27
4F：→ rekp:均衡的P/Y組合，即IS與LM聯立。AS為勞動市場與生產函數達均衡 04/30 00:30
5F：推 celestialgod:而且eco101班版 版主那篇文章 開燈有答案 04/30 00:30
6F：→ celestialgod:670篇....按\選2/3開燈 即可看到連結 04/30 00:31
7F：推 rekp:本題可用MPn=W/P代入生產函數得其解，其實應該翻翻書可以找到 04/30 00:33
8F：→ rekp:該怎麼寫的線索才是:) 04/30 00:34
9F：推 celestialgod:樓上超認真回答 04/30 00:34
