A. (1) and (3) only
B. (1) and (4) only
C. (2) and (3) only
D. (2) and (4) only
題目問長期LRAS/Yf的影響因素,有一定數量同學見到「amnesty (特赦) to illegal immigrants」一項太新穎,選左B,結果非常慘烈。
我們學長期Yf時,有4大因素可以增加潛在產出:
人力資源human capital、實際資本physical capital、科技tech、天然資源natural resources
看看題目4項選擇:
(1) 環境保護法規限制廠商生產,絕對談不上增加Yf
(2) 特赦是給illegal immigrants居民身分(同學如有留意(例如港大醫學院的Betty就是非常好的例子),human capital 增加,Yf增加
(3) 少左外勞,human capital減少,Yf減少
(4) 辦教育吸引專才,human capital 增加,Yf增加
Ans: D
