『正確答案』ACD 【例題2單選題】（2009年）在其他條件不變的情況下，如果連續(xù)增加勞動的投入，在總產量達到最大值時，勞動的邊際產量（?。?。
A.大于零
B.小于零
C.等于零
D.等于平均產量

『正確答案』C

規(guī)模報酬也稱規(guī)模收益，是指在其他條件不變的情況下，企業(yè)內部各種生產要素按照相同比例變化時所帶來的產量的變化。規(guī)模收
9、益研究的是企業(yè)的長期生產決策問題。
根據生產規(guī)模和產量的變化比例的比較，可以將規(guī)模報酬分為三類：
（1）規(guī)模報酬不變，就是產量增加的比例等于各種生產要素增加的比例。
（2）規(guī)模報酬遞增，即產量增加的比例大于各種生產要素增加的比例。
（3）規(guī)模報酬遞減，即產量增加的比例小于各種生產要素增加的比例。
多數行業(yè)會有一個適度最佳規(guī)?；蜻m度規(guī)模，此時企業(yè)的單位生產成本最小。
三、成本函數和成本曲線
（一）成本的含義（掌握）
1.機會成本：當一種生產要素被用于生產單位某產品時所放棄的使用相同要素在其他生產用途中所得到的最高收入。
2.顯成本與隱成
10、本
顯成本是指企業(yè)購買或租用生產要素所實際支付的貨幣支出。
隱成本是指企業(yè)本身所擁有的、并且被用于該企業(yè)生產過程的那些生產要素的總價格。實際上是自有要素的機會成本。
3.經濟利潤
在經濟學中，企業(yè)所有的顯成本和隱成本之和構成了企業(yè)的總成本。企業(yè)的經濟利潤是指企業(yè)的總收益和總成本之間的差額。企業(yè)所追求的最大利潤，指的是最大的經濟利潤。
經濟利潤也稱為超額利潤，企業(yè)的隱成本一般稱為正常利潤。
【例題1單選題】（2007、2008年）機會成本是指當一種生產要素被用于生產某產品時所放棄的使用該生產要素在其他生產用途中所得到的（?。?
A.最高收入

1.成本函數的含義和類型
成本函數：表示企業(yè)總成本與產量之間關系的公式。
由于考察期的不同，分為短期成本函數和長期成本函數。
短期成本函數：有固定成本與可變成本之分。C=b+f（q）
長期成本函數：無固定成本， C=f（q）
短期成本函數和長期成本函數的區(qū)別
13、在于是否含有固定成本，是否有固定成本和可變成本之分
2.短期成本函數分析
?。?）短期總成本
短期總成本=總固定成本+總可變成本
TC=TFC+TVC
固定成本是指在短期內不隨產量增減而變動的那部分成本，如廠房和設備的折舊、管理人員的工資費用等。
（2）平均成本
平均成本（平均總成本，單位產品成本）分為平均固定成本與平均可變成本
ATC= TC /Q=AFC+AVC=TFC/Q+TVC/Q
?。?）邊際成本
邊際成本是增加一個單位產量時總成本的增加額。
邊際成本是產量變動引起的可變成本的變動。
【例題1單選題】
14、短期成本函數和長期成本函數的區(qū)別在于是否含有（ ）。
A.固定成本
B.可變成本
C.邊際成本

A.0
B.150
C.100
D.300
[答疑編號2883030113]
『正確答案』C （三）短期成本曲線（熟悉）
1.總成本、總固定成本和總可變成本曲線
在成本曲線中，橫軸時表示產量，縱軸表示成本
16、。
?。?）總固定成本曲線是一條平行于橫軸的直線。
?。?）總成本曲線是從縱軸一個截點，即產量為零時總成本等于固定成本的那個點開始，隨產量增加而逐步上升的曲線。剛開始以遞減的速度上升，之后以遞增的速度上升。
?。?）總可變成本曲線從原點出發(fā)，之后隨產量增加而上升。
總可變成本曲線和總成本曲線的變動規(guī)律是一致的。

"If we dont do that it will go on and go on. We have to stop it; we need the courage to do it."
His comments came hours after Fifa vice-president Jeffrey Webb - also in London for the FAs celebrations - said he wanted to meet Ivory Coast international
22、Toure to discuss his complaint.
CSKA general director Roman Babaev says the matter has been "exaggerated" by the Ivorian and the British media.
Blatter, 77, said: "It has been decided by the Fifa congress that it is a nonsense for racism to be dealt with with fines. You can always find money from
23、 somebody to pay them.
"It is a nonsense to have matches played without spectators because it is against the spirit of football and against the visiting team. It is all nonsense.

They defeated Australia in the Four Nations final in 2010 and the last World Cup, and know they can rise to the big occasion.
