本研究以1972年第一季到2015年第四季的年資料和季資料探討是民間消費領先股票市場報酬,還是股票市場報酬領先消費。本文採用向量自我迴歸模型及Granger因果關係檢定,分析民間消費與股票市場報酬之間的因果關係與其領先效果,最後再用變異數分解及衝擊反應分析,來研究在其他衝擊不變之下,變數變動對相互之間的影響。本文另外將1982年到2015年的消費細分為耐久財、半耐久財、非耐久財和服務財等再進行實證研究。本文的實證結果發現(1)股票市場報酬對民間消費具有因果關係,亦具有領先效果,分別在年度上領先一年,在季資料上則領先兩季,顯示股票市場報酬具有領先效果。(2)在消費細項上,消費性耐久財對股票市場報酬具有弱顯著的因果關係,並且反過來領先股票市場報酬一年。
This paper investigates the lead or lag relationship between consumption and market return. The sample period is covering about 44-year period from 1972 to 2015. The results of VAR model and Granger Causality test show that market return is to be a leading indicator for consumption. In addition, this study also investigates the lead or lag relationship between market return and consumption classified items. The sample period is covering about 34-year period from 1982 to 2015. Overall, the results show that market return roles a price discovery (predictability) and can be a good predictor for competent authority in consumption. Additionally, the result also shows that consumption-durable goods play a weakly significantly price discovery (predictability) role for market return whereas other classified items show an insignificant results.
