1.if the economy moves from a steady state with positive population
growth to a zero population growth rate,then in the new steady state
total output will be-------and growth of output per person will be
-----.

(B)lower;the same as it was before
答案是這個。

但我的想法是運用
dY/Y=dA/A+dK/K+dL/L..假如dL/L變為0，則dY/Y變小
畫圖呈現steady state時，n假如變成0了，(n+d)線會變嗎??
假如不變，則k*就不會變了，對嗎?
(我是我的想法，打字到一半才知道今天想錯方向了orz)

2.assume that some large foreign countries decide to subsidize investment
by instituting an investment tax credit.assuming that the home country
is a small open economy,then the home country's real exchange rate.
(B)will rise and its net exports will fall

答案是這個，但是我覺得有點怪怪的
因為今天外國在實行投資租稅減免，導致國內資金流出至國外增加，匯市出現ED
E上升，又E上升表本國貨幣貶值，而有利出口，因此淨出口增加。

因此我選
(D)will rise and its net exports will rise
請各位幫小弟看一下，是否我有分析錯誤的地方..
