[考試] 兩題總體經濟學題目

[decrepit (破舊的)]

科目:總體經濟學

問題:

1. One new technology is invented to increase production of automobiles
   and reduces the marginal product of labor. Then, the labor demand
   and the wage rate will decrease.

這題是是非題。我的疑問是，為何看題目敘述是技術進步，卻又提到MPL下降
那生產曲線和勞動需求線究竟是上移還下移?

2. Which are the properties of a Cobb-Douglas production function
   that is constant scale to return: (字很多...我只寫出我有疑問的喔@@)
   (A) zero accounting economic profit
   (E) zero ecnomic profit

是複選題。我這邊的參考解答是兩個都有選
但我不知道生產函數和利潤是如何扯上關係的?
可以請高手們說明一下嗎? 謝謝您的解答~

推 moondark92:"accounting economic profit" 題目打錯?
→ moondark92:市場完全競爭時,規模報酬就會和profit扯上關係
→ decrepit:對@@ 應該是accounting profit而已 打錯拍謝
