✅The concept of macroeconomics
一开始肯定少不了define macroeconomics
Macroeconomics是学country‘s economic activities。例如，problem of inflation， level of unemployment，balance of payment等
Compare between macroeconomics and microeconomics
左边是microeconomics，右边是macroeconomics。
Macroeconomic goals
1.Achieving Full Employment
🔎少于6%的失业率就代表达到full employment
🔎如果失业率高，代表资源没有用到optimum
2.Maintaining Price Stability
🔎没有price fluctuation
🔎general price increase会导致inflaction
🔎general price decrease会导致deflaction
3.Sustainable Good Economic Growth
🔎提高生活水平
🔎增加output
4.Fair Equitable Distribution of income
🔎解决贫富悬殊的问题
🔎达到相近的收入
5.Competitive International Trade
🔎达到更高的生产
🔎经济福利
6. Satisfactory Equilibrium in Balance of Payments
🔎import>export 亏
🔎import<export 赚
The problem of Macroeconomics Goals无法同时达到两个macro goal
1.To achieve full employment and maintain price stability
🔎政府为了减少失业率，减少tax税，增加津贴。 当政府给予津贴后，市场上就需要很多人手，随之失业率会减少。当失业率减少后，达到了full employment，人民的经济能力就会提高，这会导致demand增加，人民开始疯狂购物，故此general price就也会增加，导致inflation。Inflation发生后，消费者的消费能力就下降，接而导致investment下降，失业率又增加。
2.To achieve economic growth and maintain price stability
🔎为了达到economic growth，政府必须要鼓励investment。怎样鼓励investment？减少interest rate，那么investment level就会增加。Investment增加会导致就业机会增加，国家生产力也会增加。就业机会增加，那么消费能力就会增加，general价格就会增加（inflation），那么就达不到price stability了。为了让general price stable，政府就必须调高interest rate，减少investment，就业机会减少，人民消费能力减少，那么economic growth就无法达到。
3.To achieve economic growth and equilibrium in balance of payment
🔎当我们的经济成长速度过高，人民就会增加消费奢侈品。当人民收入增加，自然而然会购买更多import的货多过local的货，会造成 import>export，就导致deficit in the balance of payment。政府只能减少economic growth来减少人民不断购买进口货
