指導教授 : 聶建中

摘要


研究以黃金價格、石油價格及美元指數為研究標的,實施期間, 2006年1月至2015年12月,共120個月期間,利用非線性門檻誤差修正模型架構,分別研究美元指數對黃金價格與石油價格其相互間之長短期非線性因果關係。在研究方法上,採用Enders and Granger(1998)門檻自我迴歸模型(TAR)以及動差門檻自我迴歸模型(M-TAR)進行門檻共整合檢定,再進一步利用Enders and Granger(1998)及Enders and Siklos(2001)門檻誤差修正模型(TECM)來捕捉黃金價格、石油價格及美元指數之長短期非線性不對稱效果。 從實證結果發現在線性PP、KPSS與NP單根檢定法,檢測石油價格及美元指數資料皆為I(1)數列。而在門檻共整合檢定部份,綜合發現,黃金價格、石油價格及美元指數皆存在有長期均衡的非對稱共整合關係。最後,由門檻誤差修正模型因果關係檢定綜合發現,在短期,黃金價格對美元指數具有單向的短期因果關係;而原油價格和美元指數不具有短期因果關係。在長期,黃金價格、石油價格和美元指數之間具有單向的長期因果關係。

並列摘要


This paper empirically investigates US dollar effects of Gold price and Oil price. This study employs the newly threshold error-correction model (TECM) elaborated by Enders and Granger and Enders and Siklos, assuming the nature of the relationship between the variables is on the basis of non-linearity. The empirical evidence suggests that there is a long-run equilibrium relationship between Gold price , Oil price and US dollar. In addition, the results of TECM Granger-Causality tests show a short-run causal relationship exists between Gold price and US dollar. And no short-run causal relationship exists between Oil price and US dollar.
