Indifference Curves Cannot Intersect!(不相交!) 2 From I1,X-y. From 12> Xz Therefore y cZ

Indifference Curves Cannot Intersect ! (不相交!) x2 x1 x y z I1 I2 From I1 , x ~ y. From I2 , x ~ z. Therefore y ~ z

Indifference curves cannot Intersect From I1,xy. From I2, X MZ. Therefore y aZ. But from I1 and l2 we see >Z, a contradiction

Indifference Curves Cannot Intersect x2 x1 x y z I1 I2 From I1 , x ~ y. From I2 , x ~ z. Therefore y ~ z. But from I1 and I2 we see y z, a contradiction. p
