巴罗中级宏观经济学习题第1章

Barro Chapter 1

TRUE/FALSE

1. Macroeconomists study the amount of employment and unemployment.

错。宏观经济学研究的是一个国家的全面的或总的经济运行情况。我们研究以GDP衡量的一个国家的总的商品和服务的产值是如何决定的。我们将GDP分解为各个重要的组成部分并进而分析他们：消费、总投资、政府采购的商品和服务、以及商品和服务的净出口。我们还要考察就业和失业。

2. Macroeconomists study the price of individual products like beer.

错。我们考察一个国家中生产的商品和服务的美元价格。我们考察一个典型的或平均的价格时，我们指的是一般物价水平，我们也研究工资率、租赁价格、利率。我们研究一个以上国家的经济时，我们可以研究汇率。研究单个产品的价格只是一种商品的价格而已。

3. When the gross domestic product is growing, it is called inflation.

错。通胀指物价水平的持续地上涨，商品和服务的价格一直在增长或维持在一个很高的价位。

4. A recession is when GDP is falling toward a trough.

当实际GDP下降或跌到低谷时，经济就处于衰退期。当实际GDP增加并向高点或顶点移动时，经济就处于景气期，或称经济扩张。

5. If price is below equilibrium in a market, then quantity supplied will be less than quantity demanded.

对。
