微观经济学问题,说出为什么
Suppose Tim enjoys coffee (C) but is sickened by tea (T).Which of the following utility functions would best represent Tim's utility function for coffee and tea?
AU = C * T
B U = C / T
C U = T / C
D U = CT
答
基数效用论（边际效用）：假设 Uc是10,Ut是-5（Tim喜咖厌茶）U=Uc+Ut
序数效用论（无差异曲线）：Tim偏好咖啡,厌恶茶.所以总效用与咖啡成正比与茶成反比.
U = Uc / Ut
综上是B
