[考試] 經濟學
來源: 94成大企研經濟學
科目:經濟學
問題:The slope of a production possibility frontier that displays increasing
oppotunity cost is ?
(A) positive and constant
(B) negative and constant
(C) steeper near the horizontal intercept than near the vertical intercept
(D) steeper near the vertical intercept than near the horizontal intercept
ans:(C)
我的想法:我一開始寫D ，當初是想X機會成本上升，那就會少X多Y 。
請問是我誤解題意，還是誤解答案，還是根本想法出錯 。 感謝
我覺得應該是我想錯了，因為如果想成Y機會成本上升，那答案就是C
但是我找不到適當的理由解釋。
