一道宏观经济学题

一道宏观经济学题a）看表Cakes。帕特正在开一家面包店制作和销售特别的生日蛋糕。如果她购买一台，两台或三台搅拌机，她估计的固定和平均可变成本如表所示。假设平均可变成本不随输出量而变化。假设Pat曾经生产过100个蛋糕，但她的需求突然增加，因此她开始生产200个蛋糕。解释她的平均总成本在短期和长期内将如何变化。
b）看表Cakes。帕特正在开一家面包店制作和销售特别的生日蛋糕。如果她购买一台，两台或三台搅拌机，她估计的固定和平均可变成本如表所示。假设平均可变成本不随输出量而变化。假设Pat曾经生产200个蛋糕，但她的需求突然增加，因此她开始生产400个蛋糕。解释她的平均总成本在短期和长期内将如何变化。

a) Look at the table Cakes. Pat is opening a bakery to make and sell special birthday cakes. Her estimated fixed and average variable costs if she purchases one, two, or three mixers are shown in the table. Assume that average variable costs do not vary with the quantity of output. Suppose that Pat used to produce 100 cakes, but she has a sudden increase in demand, so that she begins to produce 200 cakes. Explain how her average total cost will change in the short run and in the long run.

Answer 1

算不来，不过制造业一直都这样。需求小成本高，需求大成本低，然需求是线性的还是突发的非常重要，否则增加制造就是加速死亡。

Answer 2

首先理解MPC指的是边际消费倾向， I指的是投资。 1/（1-0.6）X 100=250万 这是一个公式。

Answer 3

我们这里都是去专门包办酒席的饭店，这样都省事！每桌不过200元，当地的特色美食也很实惠！
