就是讨论下科技是个不可忽视的因素参与在经济发展中。
SOLOW MODEL Y=A.F(K,L) in which we include technology since it has been identified as a key contributor to economic growth.
Using the formula Δ(C*D)= ΔC*D+C*ΔD where ΔC and ΔD represent small increments of C and D, show starting from Y=AF(K,L) that
ΔY/Y=(ΔA/A)+(ΔF/F)and that ΔA/A=(ΔY/Y)-A * [(mpk.ΔK+mpl.ΔL)/Y] 不好意思,公式不会用分子分母样子打出来,所以搞的很复杂,加了很多括号。
where mpk=F’K and mpl=F’L stand for the marginal productivity of capital and labour respectively
有没有高人可以指点下,万分感谢,实在搞不清楚怎么写。。。谢谢
