The manufacturing sector of a given country is endowed with 100 units of capital and operates under the production function

Q=AL0.5K0.5 (0.5都是指0.5次方)

Where Q is the quantity of output, L and K are the inputs of labor and capital respectively, and A is a content equal to 100.

B. If the planners’ preference function W – expressed in monetary terms – includes both Q and the amount of employment in the manufacturing sector (L) explicitly and is defined over the relevant range as

W=V1Q+V2L; V1=2 and V2=4

Where V1 and V2 are the relative weights of Q and L in the objective function W, what is the most which the planners would be willing to pay for an additional unit of K?

不太清楚什么是preference function, 是不是要把它最大化啊？可是constraint function 没有啊。 大家帮忙看看
