※ 引述《Expsun (无限燃烧)》之铭言： : 学校:国立暨南国际大学 : 教师:赖法才 : 科目:个体经济学 : 题目: : The price of an antique is expected to rise by 8% during the next year. : The interest rate is 12%. You are thinking of buying an antique and : selling a year from now. You would be willing to pay a total of 800 dollars : for the pleasure of owning the antique for a year. How much would you be : wiliing to pay to buy this antique? : a.6,666.67 dollars : b.20,000 dollars : c.800 dollars : d.16,800 dollars : e.8,000 dollars : 我的想法:不知道为什麽这题答案会是直接用800/0.04=20000 : 4%似乎是实质利率？12%-8%=4% : 跟这题...的关联性何在？多谢指教。 : 要从书本上的概念想出这麽多东西真的好困难... : 有没有人可以推荐一下读Varian课本如何切入理解？ 还没看过 Varian 这部份的内文与习题 但小弟对於此题目的直觉是： 享受持有古董一年乐趣所愿意花的钱 = 直接买进古董并於一年後出售其此期之机会成本 等号右边就是把钱省下来拿去存的利息所得减去古董的增值，X * 12% - X * 8% 故，800 = X * (12%-8%) X = 20,000 (dollars) 有错还请指正。 --
