Consider the following production function:
Y; = AK“H?-«L%
where Ktis capital, Htis human capital, Leis the amount of workers and A is the (constant) level of technology.
(i) Does this production function satisfy all the neoclassical properties. Discuss the meaning of each property INTUITIVELY.
Imagine that parents invest in the human capital of their children up to the point where the MARGINAL PRODUCT OF PHYSICAL
CAPITAL, Kt, is equal to the MARGINAL PRODUCT OF HUMAN CAPITAL, Ht.
