科目: 经济学
问题:
Concerning the maximizationo of output subject to a cost constrant, which
of the following statement (if any) are true?
(A) At the optimal input combination, the slope of the isoquant must equal
the slope of the isocost line.
(B) The optimal solution occurs at the boundary of the feasible region of
input combinations.
(C) The optimial solution occurs at the point where the isoquant is tangent
to the isocost lines.
(D) all of the above (E) none of the above
我的想法:
我知道这是很基本的问题... 但我想问的是，如果是一般凸向原点的等产曲线
那答案应该是选D。但若考虑到特殊形状(ex.完全替代、完全互补)的等产曲线
是否答案就只剩B可以选?? 那我要如何知道出题者想问的是哪种情况呢?
敬请大大们不吝指教~谢谢
