2、條件才能讓模型得以認(rèn)定。第一種方法是以結(jié)構(gòu)性向量自迴歸模型(structuralVARmodel)為架構(gòu)，並透過(guò)額外認(rèn)定條件賦予干擾項(xiàng)經(jīng)濟(jì)意義。這種方法主要係藉由經(jīng)濟(jì)理論對(duì)干擾項(xiàng)變異數(shù)，共變異數(shù)矩陣中待定係數(shù)找出認(rèn)定所需的額外條件。由於額外條件僅讓結(jié)構(gòu)性向量自迴歸模型足以認(rèn)定(justidentified)，故有無(wú)法利用統(tǒng)計(jì)檢定方法檢驗(yàn)認(rèn)定這些條件是否成立缺點(diǎn)。第二種方法則是利用完整設(shè)定的經(jīng)濟(jì)模型以及理性預(yù)期假設(shè)說(shuō)導(dǎo)出對(duì)模型待估的結(jié)構(gòu)性

3、參數(shù)(structuralparameters)的跨式限制條件(crossequationrestrictions)。介紹不同類型認(rèn)定條件後，本課程亦將介紹如何估計(jì)結(jié)構(gòu)性時(shí)間序列模型以及檢定不同型式的限制條件。II.II.II.課程內(nèi)容課程內(nèi)容課程內(nèi)容課程內(nèi)容3KingRobertG.WatsonMarkW.(1994).“ThePostWarU.S.PhillipsCurve:ARevisionistEconometricHisty.
