Study the following graph carefully and write an essay. You should:
1) describe the graph and interpret its meaning, and
2) point out the problems and give your comments.
Your composition should be more than 150 words. You should write your composition neatly on ANSWER SHEET 2 .
写出程序运行结果。
classPoint{
intx,y;
Point(intx,inty){
this.x=x;
this.y=y;
System.out.println("父类构造函数被调用!");
}
}
classCircleextendsPoint{
intradius;
Circle(intr,intx,inty){
super(x,y);
this.radius=r;
System.out.println("子类构造函数被调用!");
}
}

publicstaticvoidmain(Stringargs[]){

}
运行结果:
(1)假定其中一种产品实施配给。解释为什么消费者的境况可能变差。
(2)假定其中种产品被固定在当前市场价格以下的水平,因此消费者不能想买多少就买多少。你觉得消费者的境况是变好了还是变差了?
Draw a budget line and then draw an indifference curve to illustrate the satisfaction - maximizing choice associated with two products. Use your graph to answer the following questions.
a Suppose that one of the products is rationed. Explain why the consumer is likely lo be worse off.'
b. Suppose that the price of one of the products is fixed at a level below the current price. As a result, the consumer is not able to purchase as much as she would like. Can you tell if the consumer is better off or worse off?
