如果偏好是单调的,经由原点的对顶线与每一条无差异曲线只会相交一次。你能严格地证明这一点吗?(

如果偏好是单调的,经由原点的对顶线与每一条无差异曲线只会相交一次。你能严格地证明这一点吗?(提示:如果它同某条无差异曲线相交两次,会出现什么情况呢?) We claimed in the text that if preferences were monotonic,then a diagonal line through the or i-gin would intersect each indifference curve exactly once.Can you prove this rigorously?(Hint:what would happen if it intersected some indifference curve twice?)
