宏觀知識點總結(jié)Chapter26theexchangerateandbalanceofpayment1.名義利率和實際利率的概念，要區(qū)分；二者的關(guān)系，那個公式。明白一國貨幣升值表示什么意思。（掌握）2.tradedweightedindex(了解)3.對一國貨幣的供給和需求的分析一，供給和需求決定匯率，要知道哪些因素影響一國貨幣的供給和需求，相應(yīng)的曲線在圖上會怎么移動（重點）。二，對一種貨幣的需求是對另一種貨幣的供給，要清楚某一種貨幣供給需求變化后，另一種貨幣的供給和需求會如何變化。（重點）4.利率平價和購買力平價（掌握）5.internationaltrade(了解)6.匯率政策。理解什么是浮動匯率、固定利率和crawlingpeg。注意區(qū)分。（掌握）Chapter27(AD-ASmodel)ThemainpurposeofAD-ASmodel:explainchangesinrealGDPandpricelevel,whichleadstobusinesscyclefluctuationsaroundpotentialGDP.1、區(qū)分宏觀中的長短期宏觀中的長短期主要以價格行為加以區(qū)分：在長期中，價格是具有伸縮性的，價格水平能夠調(diào)整到充分就業(yè)的均衡狀態(tài)；在短期中，價格是具有粘性的（sticky），實際GDP可能等于、大于、小于潛在GDP.2、總供給（AggregateSupply）2.1總供給是描述實際GDP供給量與價格水平的關(guān)系。外生變量外生變量ThequantityoflaboremployedThequantityofphysical,humancapitalQuantityofrealGDPsuppliedThestateoftechnology
