宏观经济学-导论
• 一、宏观经济学与微观经济学
• 1、微观与宏观的界定
• 微观经济学是研究个别厂商与家庭在市场上如何扮演 产品供给者、消费者和要素供给者等行为，这些供需 行为如何决定个别物品、劳务的价格、数量；以及这 些市场的机能与政府如何影响资源的配置。分析的目 的是要了解资源的配置是否满足人们的要求。由于分 析的焦点是“相对价格”的决定与影响，因此又称为 价格理论。
• 二、宏观经济问题
• 1、国内问题
• Inflation • Unemployment • The Rate of Economic Growth • Movements in the Business Cycle
• 2、国际问题 • 外汇收支平衡 • 贸易发展与汇率
Macro Problem #1: Inflation
– Since he never had any trouble moving the inventory, Jim decided to do the same thing again -- even though it meant taking out a big short term loan to finance the expansion.
Some Inflation Indices
• The Producer Price Index is based on a number of important raw materials.
• The Consumer Price Index or “CPI” is calculated by pricing a basket of goods and services purchased by a typical household.
