來源: (例如: XX 年度高考, XX 年度研究所考)
科目:經濟學
問題:Richard Miller,a wall street trader,says he is a risk neutral.
Suppose we let 0 be the utility he attaches to $100000 and 1 be
the utility he attaches to $200000.If what he says is true,
what is the utility he attaches to $40000?
我的想法:由題目可以知道
U(100000)=0 U(200000)=1
利用風險中立者的特性 預期所得=預期效用
但算出來機率是負的 有點奇怪
不知道可不可以利用風險中立者的圖形去求出相對應的值
想了老半天想不出來 煩請各位高手解答摟 謝謝
