问题如下:
习题4
(This problem requires the use of calculus.)
Consider a Cobb-Douglas production function with three inputs.
K is capital (the number of machines)，
L is labor (the number of workers)，and H is human capital (the number of
college degrees among the workers).The production function is
Y=K^1/3 L^1/3 H1/3 .
a. Derive an expression for the marginal product of labor. How does an
increase in the amount of human capital affect the marginal product of labor?
b. Derive an expression for the marginal product of human capital.
How does an increase in the amount of human capital affect
the marginal product of human capital?
可以请能人指点指点吗> < 我不清楚他有关於微积分的地方要怎麽做~~~
谢谢!
P.S 函数的地方写得有点怪 用念的就是K的三分之一次方*L的三分之一次方*H
的三分之一次方

2F：→ ALegmontnick:查一下微积分的书,印象会深很多.easy come,easy go. 10/19 20:19
3F：推 oldhand:a.对h微一次 b对h微两次 因该是这样吧XD 话说这有点像作业 10/19 21:24
4F：→ patriciachen:恩~想问一下 为什麽人力资本的改变影响的不是Y而是 10/19 23:13
5F：→ patriciachen:MARGINAL PRODUCT OF LABOR???是因为影响了labor就会 10/19 23:14
6F：→ patriciachen:影响总产出吗?? 10/19 23:15
