消费函数中的自发消费和边际消费倾向变动时,IS曲线会有什么样的变动?

答案

参考答案:

自发消费增加会使IS曲线右移,自发消费减少,IS曲线左移。边际消费倾向增大,将使IS曲线的斜率变小。因为边际消费倾向的增大,意味着一定的收入中会有更多的收入用于消费,更少的收入用于储蓄。为使储蓄和一定利率水平上的投资相等,就需要有更多的收入来提供相应的储蓄。当更多的收入和一定的利率对应时,IS曲线就会变得更平坦。同理,边际消费倾向变小,IS曲线的斜率变大。

      Japanese students work very hard but many are unhappy. They feel heavy pressures (压力) from their

parents. Most students are always told by their parents to study harder and better so that they can have a

wonderful life in the future. Though this may be a good idea for those very bright students, it can have terrible

results for many students who are not gifted (有天赋的) enough. Many of them have tried very hard at school

but have failed in the exams and have their parents lose hope. Such students felt that they are hated by

everyone else they meet and they don't want to go to school any longer. They become dropouts.

      It is surprising that though most Japanese parents are worried about their children, they do not help them

in any way. Many parents feel that they are not able to help their children and that it is the teachers' work to

help their children. To make matters worse, a lot of parents send their children to those schools opening in the

evenings and on weekends-they only help the students to pass the exams and never teach them any real sense

of the world.

      Many Japanese schools usually have rules about everything from the students' hair to their clothes and

things in their school bags. Child psychologists (心理学家) now think that such strict rules are harmful to

the feelings of the students. Almost 40% of the students said that no one had taught them how to get on with

others, how to tell right from wrong and how to show love and care for others, even for their parents.
