II、簡答題(35%，寫出重點即可，亦可利用數學或圖形做輔助)
1.(20%)假設現在處於均衡狀態，請分析以下事件發生將對括號中的市場的供需曲線造成
何種影響？在原均衡價格之下，產生超額供給或超額需求？價格將如何調整？
a. 台電調整電費，牛肉麵店老闆大喊吃不消。(牛肉麵)
b. 林來瘋席捲全世界，林書豪身價水漲船高。(球員卡)
c. 天秤颱風重創南台，高麗菜收成慘不忍睹。(高麗菜)
d. iPhone5 隆重上市，iPhone4 乏人問津。(iPhone4)
2.(15%)薄利多銷是一種商場的經營策略。意圖在於降低每單位的利潤，提高銷售數量以彌
補價降的部分。但學過經濟學的你，應該明白並不是每樣商品都適合這樣的銷售策略。試
利用彈性的觀念回答下列問題：
a. 何種市場較有可能採用薄利多銷之策略？請舉例出1~2種市場。
b. 試說明彈性大小和總收益之關係
c. 為何同樣遭受到鉅額虧損，鐵路局的策略是提高票價，而中國造船公司卻採取降價求
售呢？
III、計算問答題(25%)
a. 假設一經濟體有10個偏好相同的人，每個人的需求函數為P=40-Q；且市場中存在20家
相同的供給商，每家的供給函數為Q=10+2P。
請算出市場的均衡價格以及均衡數量。(6%)
b. 承上題，若今天廠商的生產技術改變，
使得每家供給商的供給函數變成Q=15+2P
請算出改變前後兩點均衡點的弧彈性值(8%)，並註記是何種彈性。(2%)
(請簡化為最簡分數，若取小數則計算至第二位四捨五入)
c. (9%)給定一財貨的需求函數如下：
Qx = 130 -2Px + 0.3Py - 0.7I
請回答以下問題：
(1) X財貨符合需求法則嗎？為什麼？
(2) X財貨是正常財還是劣等財？為什麼？
