標題[討論] neoclassicl real wage & rental pric of captial
時間Sun Jun 22 04:43:48 2008
原題如下
Based on the neoclassical theory of distribution , the real wage
will fall and real rental price of capital will rise if immigrant labor
force raises significantly.
ANS : yes
有解答
但不懂的地方是 real wage = MPn= f(k*)-k*f'(k*)
rental price of capital = MPk = f'(k*)
MPk 知道如何求出
MPn 呢??
懇請高手回答

1F：推 daniel955377:K不變 N↑ k↓ 61.229.98.191 06/22 16:01
2F：→ daniel955377:dMPn/dk = f'(k) - f'(k) - f''(k) 61.229.98.191 06/22 16:02
3F：→ daniel955377:= - f''(k) > 0 61.229.98.191 06/22 16:03
4F：→ daniel955377:k↓使MPn↑ 61.229.98.191 06/22 16:03
5F：→ lemonkai:我不懂的是MPn 為何 = f(k*)-k*f'(k*)218.166.206.117 06/22 17:19
6F：推 yivtfa:解答是用成長理論來解釋..翻一下後面幾章吧 210.209.188.19 06/22 17:29
7F：→ yuekun:樓樓上 這在romer ch2 用力給他微下去答案 61.228.105.123 06/22 17:31
8F：→ yuekun:會出來 主要是F裡面那個F/L會衍生一堆東西 61.228.105.123 06/22 17:32
9F：→ yuekun:我手邊沒書但我確定是這樣算沒錯 61.228.105.123 06/22 17:33
10F：→ lemonkai:樓上的 romer CH2 是??218.166.206.117 06/22 17:35
11F：→ yivtfa:翻一下總經"內生成長"的章節看一下你就懂了 210.209.188.19 06/22 17:41
12F：→ yivtfa:圖形上MPK是切線斜率.MPN剛好是那中間的差 210.209.188.19 06/22 17:43
13F：→ lemonkai:MPN=每人平均消費嗎??218.166.206.117 06/22 19:24
14F：→ lemonkai:從y=MPk*K+MPn*N 來推 因該還要在除N才對218.166.206.117 06/22 20:06
15F：推 daniel955377:MPn是marginal product of labor 61.229.111.219 06/22 21:29
16F：推 daniel955377:MPn = dN*f(k)/dN 61.229.111.219 06/22 21:31
17F：→ daniel955377:= f(k) + N*df(k)/dN 61.229.111.219 06/22 21:32
18F：→ daniel955377:= f(k) + N*df(k)/dk*dk/dN 61.229.111.219 06/22 21:33
19F：→ daniel955377:= f(k) + N*f'(k)*d(K/N)/dN 61.229.111.219 06/22 21:35
20F：→ daniel955377:= f(k) + N*F'(k)*(-K/N^2) 61.229.111.219 06/22 21:36
21F：→ daniel955377: f才對 61.229.111.219 06/22 21:36
22F：→ daniel955377:= f(k) - f'(k)*k 61.229.111.219 06/22 21:37
