宏观知识点总结
Chapter26 the exchange rate and balance of payment 1. 名义利率和实际利率的概念,要区分;二者的关系,那个公式。明白一国货币升值表示什么意思。(掌握)
2. traded weighted index(了解)
3. 对一国货币的供给和需求的分析
一,供给和需求决定汇率,要知道哪些因素影响一国货币的供给和需求,相应的曲线在图上会怎么移动(重点)。
二,对一种货币的需求是对另一种货币的供给,要清楚某一种货币供给需求变化后,另一种货币的供给和需求会如何变化。(重点)
4. 利率平价和购买力平价(掌握)
5. international trade (了解)
6. 汇率政策。理解什么是浮动汇率、固定利率和crawling peg。注意区分。(掌握)
Chapter 27 (AD-AS model)
The main purpose of AD-AS model: explain changes in real GDP and price level, which leads to business cycle fluctuations around potential GDP.
1、区分宏观中的长短期
宏观中的长短期主要以价格行为加以区分:在长期中,价格是具有伸
缩性的,价格水平能够调整到充分就业的均衡状态;在短期中,价格是具有粘性的(sticky ),实际GDP 可能等于、大于、小于潜在GDP.
2、总供给(Aggregate Supply )
2.1总供给是描述实际GDP 供给量与价格水平的关系。
The quantity of labor employed The quantity of physical, human capital
Quantity of real
GDP
supplied The state of technology
AS
Price level
2.2
总供给关系取决于时间范围
企业的产品服务价格具有伸缩性---长期总供给曲线
企业的产品服务价格具有黏性—
短期总供给曲线
2.2.1长期总供给(long-run aggregate supply )
a 、In the long run, the money wage rate changes in step with the price level;
b 、Try to explain why the LAS curve is vertical.(重点)
the price level
change by the money wage the same percentage does not change
rate
LAS curve is vertical
2.2.2短期总供给(short-run aggregate supply )
a 、in the short run, the money wage rate, the prices of other
resources and potential GDP remain constant;
b、Try to explain why the SAS curve slopes upward.
In the short run, when the price rises real wage
declines
the cost of production employ labors
increases production(real GDP) 黏性工资模型
在超短期中,总供给曲线是水平的。
2.3总供给的变动

3、总需求(Aggregate demand )
3.1 总需求是描述实际GDP 需求量与价格水平的关系
Basic formula: Y (实际GDP 需求量)= C+I+G+(X-M) aggregate Price level demand
3.2 总需求曲线 Try to explain why the AD curve slopes downward.

Effcts Method 2 To analysis the relationship between the price level and real GDP by using the quantity theory of money.
3.3影响总需求变动的因素
Expectation ,Fiscal and monetary policy ,The world economic (这部分的变化分析要求理解掌握,课本上有具体的总结解释)
4、短期均衡与长期均衡
