※ 引述《dododino (喔耶~)》之銘言:
: 1.
: The opportunity cost of pushing the production possibility frontier outward is
: (A)the value of the increase in new capital resources required.
: (B)the value of the increase in technical improvement required.
: (C)the value of the reduction in current consuption required.
: (D)the amount by which the production possibility frontier shifts.
: 答案是C (成大國企)
: 但我覺得他是要問PPC外移的原因 不是技術進步嗎?? (相同要素生產更多產量)
推動PPF外移,不外乎技術進步、資本累積等等因素
這題應該是以S上升,導致當期C下降,進而資本累積PPF外移,所以犧牲了當期消費
: 2.
: As long as the firm is not operating efficiently, which cost always increases
: with increases in output?
: (A)MC
: (B)AFC
: (C)TFC
: (D)AVC
: (E)TVC
: 答案是E (中山財管)
: 我覺得能夠理解 但AVC也是上升的啊 如果沒說單選或複選是否該都選?
: (寫了一些題目後發現有時候題目會註明"複選"卻是單選 會沒標複選卻是負選)
TVC隨產量增加而上升是鐵不變的事實,然而AVC可能會地增或遞減,
端視產量在LAC最低點的左方還右方
: 3.
: The long run supply curve is likely to slpe upward if:
: (A)additinal firms are attended into the industry in the long run.
: (B)not all firms have the same cost of production.
: (C)diminishing marginal product sets in.
: (D)there are no barriers to entry in the industry.
: (E)economies of scale exists.
: 答案是A (93台大國企)
: 應為成本遞增產業 所以我選的是C 這樣想錯在哪? (也不知道為啥要選A)
C選項好像只能看到短期MC正斜率,但長期好像無法以邊際產量遞減解釋
但為什麼是A可能是因為獨佔就不會有長期供給線?
: 4.
: A monopolist does not produce the product as efficiently as is possible because
: (A)the average total cost of producing it is not a minimum.
: (B)the marginal cost of producing it is not a minimum.
: (C)it is earning a profit.
: (D)AR is greater than the cost of producing an extra unit of output.
: 答案是A
: 但我覺得沒有在效率生產點生產(P=MC) 也就是在AR>MR=MC處生產啊? 所以我選D
生產效率是指在AC最低點生產,所以應該是A
P=MC是達到配置效率的樣子
: 5.
: 若一獨佔者將其產品銷售至A&B兩個阻隔的市場,A市場之需求彈性為-0.8,
: B市場之需求彈性為-0.6,試問該獨佔者若依第三級差別取價則AB哪一市場之價格較高?
: 答案是A (交大管科)
: 利用反彈性定價原則會得到答案是A
: 但實際上帶數字進去算就會發現會是B
: 因為獨佔廠商應該只會在MR=MC>0的地方生產 也就是MR=P(1-1/|Ed|)要>0
: 如果彈性得絕對值<1 那就會得到負值 所以是題目的概念根本完全錯嗎?
: 或者能有更好的解釋 謝謝
這題反彈性定價不是高彈性低定價嗎?我直覺會是B較高
但MR負值的確也蠻奇怪,請高手解釋
: 6.
: 哪一個不是價格歧視?
: (A)airline charging different fares for adults and children.
: (B)dentists charging different fees for unemployment benefis recipients
: and other person.
: 答案是A (中正企管)
: 是因為大人的飛機餐跟小孩子不一樣嗎? 但同樣都是坐一個坐位啊?
: B選項是說牙醫對領失業金的人和一般人取價不同 嗎? 好怪的選項@@
A如你所述是因為成本就不同
B可能是國外的案例?不過確實是差別取價,因為看醫生花費佔所得比例較高,彈性較高
: 7.
: 假設遊樂場提供十項遊樂設施,消費者對該遊樂場設施的需求函數為P=100-10Q
: 並且玩透十項設施,如果該遊樂場收取門票四百元,並且前五項每項收費20元,
: 後五項每項收費10元,則消費者不願意買票進入該遊樂園玩,用經濟學原理說明原因
: 答案是因為門票的收取不能超過消費者剩餘 (92東海國貿)
: 這題如果要用圖示的話是畫出拗折的需求線嗎? 覺得畫不太出來
: 現在只能用需求函數算 若Q=10則P=0 CS=0.5*100*10=500
: 門票400+20*5+10*5>500 所以不買 這樣解釋好像沒用到CS的概念
: 有沒有更完善的解釋呢?
這...門票就超過保留價格,當然就不會去玩
: 8.
: Thomas Edison once said that he began making real profit on light bulbs when
: he dumped his surplus on the European market at less than the "cost of
: production". From this we can deduce:
: (A)Edison was crazy and did not want to maximize profit.
: (B)Edison understood the difference between marginal and average cost.
: (C)Edison had a peculiar definition of the term "profit"
: (D)Edison did not understand the difference between fixed and variable cost.
: 答案是A (90交大科管)
: 這題我完全看不懂他將剩餘的燈泡丟棄是在怎樣的條件下
: 又是為啥要選A 麻煩解答了
我會選B,但好像沒什麼依據..直覺是先達到生產效率後,丟棄多出來的商品會比成本低
: 再次謝謝你看完這篇文章<(_ _)>
