兩題選擇題 - 經濟

1. The demand curve for a unique product without substitutes is
a. upward sloping
b. downward sloping
c. vertical
d. horizontal

我選c 參考解答是b
想說沒有替代品 即需求彈性為0
需求曲線為直線

2. "Given the long run implication of Solow's growth model with respect to
the rate of savings, the low savings rate in Taiwan is not a problem."
This statement overlooks that over time it appears that
a. total factor productivity(TFP) and the growth rate of capital per person
are inversely related.
b. TFP and the growth rate of capital per person are positively related.
c. TFP and the difference between the growth rates of capital per capita and
population are not related.
d. saving rates and per capita growth rates are inversely related.
e. saving rates and per capita growth rates are not related.

這題在考古題出現好多次
但參考解答的答案皆不同
我找到的答案是c
有人可以解釋一下這題到底想問什麼嗎?


煩請各位高手解答 謝謝!
