學校:國立暨南國際大學教師:賴法才科目:個體經濟學題目來源：Varian 的 Test-Item File 題目: 1.Vincent Smudge's Paintings are unappreciated now. Nobody is willing to pay anything to have them on the walls. In 5 years Smudgee's work will gain enduring popularity. People will suddenly be willing to pay ＄1000 a year to have an original Smudge on their walls and will continue to be willing to do so ever after. If investors realize that this is the case and if the interest rate is and always will be r, a painting by smudge will currently be worth about a. (1000/r)[1/(1+r)^4] b. 1000/r-5000/r c. 1000(1+r)^5 d. 1000(1/r)^5 e. 200/r 我的想法:不太懂為什麼會變成a選項那樣跟以往的折現值不同嗎？ 2. A certain wine costs ＄3 a bottle to produce. It improves in taste if stored properly for a period of time. When it is newly bottled, people are willing to pay only ＄2 a bottle to drink it. But the amount that people are willing to pay to drink a bottle of this wine will rise by ＄3 a year for the next 50 years. Storage costs, not including interest, are ＄.50 per year. If the interest rate is 5% and the wine is kept by rational investors, how old will it be when it is drunk and what will be its price at that time? a. 50 years old and ＄152 b. 16 years old and ＄50 c. 50 years old and ＄153 d. 20 years old and ＄63 e. 4 years old and ＄14 我的想法：是不是酒經過儲藏的價值，到達跟人們對酒的保留價格時的那個時間跟價格啊？ p.s.我真的把課本看了很多遍了orz 很努力想看更通但是面對題目我對這章毫無招架之力不是我想當free rider Orz 拜託各位點醒我一下了Q_Q -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 125.231.11.171
