Question

宏观经济问题,技术方面
以下三种技术的特征
lPerfect substitutes
lFixed proportions
lCobb-Douglas
还有,
What would happen to x,y andπ,when w2 increase?

Answer 1

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.
