生產函數 Y=AL^(0.5)K^(0.5) K為資本 L為勞動 A=10
(1) 假如 資本成長率=0.06 勞動成長率=0.04 總合要素生產力(TFP)=0.1
試問產出成長率?
第一題很基本 就此略過
(2)base on the information given in (1) , determine the steady-state
values of the output per capital(Y/L) and consumption per capital(C/L)
in a solow growth model if the saving rate equals 0.3 and the capital stock
is depreciation at a rate 10% (0.1)?
這應該是個很簡單的經濟成長計算題
steady-state條件
s*y=(資本折舊率+勞動成長率)*k y=10*k^(0.5)
0.3*y=(0.1+0.04)*k
可解出k=459.1836
但是怎麼對到後面的解答居然不一樣
這位老師是解
0.3*y=(0.04+0.01)k
所以k=3600
接著我叫我同學算一次
他的解法
s*y=(0.1+0.04+0.1(TFP))k
k=12.5
哪個是對的阿?
我記得我的步驟應該沒錯阿
請大家幫忙一下
