Perfect substitutes: U = a*x + b*y where a,b>0

Fixed proportions: U = min(a*x,b*y)

Cobb-Douglas: U = x^a*y^b

What would happen to x,y and π,when w2 increase?

π是什么形式?这个问题不全.通常w2增加,π会减少,但是x,y的变化取决于π的形式还有你要保持产量还是成本不变.

问题3：西方经济学——宏观经济政策方面的题目已知某国的投资函数为I=300-100r ,储蓄函数为 S=-200+0.2Y,货币需求为 L=0.4Y-50r,该国的货币供给量M=250 ,价格总水平P=1 .(1) 写出IS和LM曲线方程；(2) 计算产品[数学科目]

根据均衡条件：

I=S：300-100r=200+0.2y y=500-500r 即IS曲线y=500-500r

L=M：0.4y-50r=250 即LM曲线y=625+125r

联立方程组：y=500-500r

y=625+125r

y=250 r=-0.2
