求教平狄克《微观经济学(第七版)》第3章练习题第2题的b问:
Draw indifference curves that represent the following individuals’ preferences for hamburgers and soft drinks. Indicate the direction in which the individuals’ satisfaction (or utility) is increasing.
b. Jane loves hamburgers and dislikes soft drinks. If she is served a soft drink, she will pour it down the drain rather than drink it.
给出的答案如下:请问为什么图形会是这样?
我的答案如下。因为即使Jane虽然会表现的礼貌一点,但是只要自己可以选择,则一定会把所有钱拿去买hamburgers。而且即使是如答案所示,那么Jane最终也是选择与budget line相交且utility最大的一点,那么这一点照样是在Y轴上,与我的答案无异。如果有不对的请指出来,真心求教,拜谢!
