期貨巿場效率性之再探討-季節性單根檢定

周曉萍 Unknown Date (has links)
本研究利用ADF單根檢定以及新觀點的季節性單根檢定做為分析工具,去檢測期貨巿場與現貨巿場是否存在一長期均衡關係。研究對象共有十種,分別為:能源期貨-輕原油、煤油,外匯期貨-日圓、瑞士法郎(對美元),短期利率期貨-一個月期倫敦銀行拆款利率、90天期美國國庫券,公債期貨-2年的美國中期公債、15至30年的美國長期公債,S&P500指數期貨,金屬期貨-高等級銅期貨。 過去檢測長期均衡關係所使用的單根檢定觀點假設其他頻率的單根並不存在,因此當拒絕虛無假設時,我們無法確知拒絕的原因是資料真的沒有單根的存在,抑或是資料具有季節性現象,因此納入季節性考量的HEGY檢定法,將是比較一般化的檢定方法,而且因為HEGY能夠同時檢定季節性及某些非季節性單根的存在與否,而不必假設所有季節性頻率的單根皆同時存在,所以ADF單根檢定法可視為HEGY季節性單根檢定法之特例,因此一般來說,HEGY檢定法之檢定力較ADF單根檢定法為高。 而本文實證結果亦證明,ADF單根檢定法的確無法檢定出季節性單根的有無,當季節性因素存在時,使用ADF單根檢定將可能導致錯誤的推論。

歐元利率平價說之實證研究

陳悅治, chen ,yueh-chih Unknown Date (has links)
歐元的問世,代表的是從1970年代固定匯率被打破以來,世界金融體系最大一次的變革,其對全球之金融及社會文化有很深遠的意義;因此,有關美國與歐元區間之匯率、利率及物價關係的探討遂成為國際金融市場所關心的焦點之一;本文以Frankel (1992)所提出衡量國際間資本移動性的三種利率平價說:拋補利率平價說(Covered Interest Parity,CIP) 、無拋補利率平價說 (Uncovered Interest Parity,UIP)、實質利率平價說 (Real Interest Parity,RIP)為基礎,來檢驗此三種利率平價說是否成立。在實證方法上,本文以Dickey & Fuller (1979,1981)之ADF單根檢定來確定變數之數列特性,再採Johansen (1988)之最大概似估計法,對CIP、UIP與RIP進行實證分析。實證結果發現,於1999 年 1 月至 2004 年 7 月期間,美國與歐元區間 CIP 與 UIP 同時成立,表示當兩國資產報酬率有差異時,可以經由國際間資本的移動,使得報酬率最後有趨於相等的傾向;並且接受遠期匯率為未來即期匯率的不偏估計值之虛無假設,顯示歐元與美元間外匯市場具有效率性。另外,本文之實證結果並不支持 RIP 的成立,其有可能歐元區與美國在編制物價指數時,所使用的物價項目和比重情況不同而異,因此難以表示出公正之匯價;再者由於現實之貨幣、商品市場之不完全,與人民不一定能完全預期及存在貨幣幻覺等許許多多未考慮因素下,故在諸多驗證 RIP之文獻中,亦大多顯示無法找到其均衡之平價關係。 / The emergence of Eurodollar exemplified a significant reformation in the world financial system since the fixed rate had been broken in 1970, which brings far-reaching significance to the global finance and social culture. Therefore some discussions on exchange rate, interest rate and price relationship in the range of US Dollar and Eurodollar are one of focuses the international financial market concerns; On the basis of the three kinds of interest rate parity Frankel brought forward (1992) including Covered Interest Parity (CIP), Uncovered Interest Parity (UIP) and Real Interest Parity (RIP), this research mainly proves their feasibility. For the empirical methods, the Dickey & Fuller (1979, 1981)’s ADF unit root test was used to confirm the characteristics of variable series in this research; additionally, Johansen’s maximum likelihood method (1988) was adopted to do the empirical analysis on CIP, UIP and RIP. Based on the empirical results, we found out that the CIP and UIP are tenable simultaneously in the range of tenable US Dollar and Eurodollar from 1999 January to 2004 July. That means when return on asserts between two counties has some differences, it would become towards equality lastly on the basis of international capital mobility. And the null hypothesis that the forward rate is an unbiased predictor of the future spot rate can be employed, revealing the foreign exchange market in the range of Eurodollar and US Dollar has certain efficiency. Additionally, The empirical results of this research do not support the RIP, because it would vary with different prices and proportion used while making the price index in the range of Eurodollar and US Dollar, and cannot present equitable exchange rate; furthermore, because of imperfect current currency and commodity markets, and many unconsidered factors such as people’ incompletely anticipation and money illusion, most researches for validating RIP fail to find out its balanced parity relation.

台灣貨幣政策信用傳導機制之研究

鄭輝培 Unknown Date (has links)
關於貨幣政策傳導機制的探討,包含了傳統的貨幣觀點以及信用觀點,由於傳統貨幣觀點之貨幣政策傳導機制並無法完全解釋經濟變數之變動,因此信用觀點逐漸受到許多學者的重視與討論。信用觀點所探討的貨幣政策傳導機制稱為信用管道,包含了廣義的信用管道(資產負債表管道)與狹義的信用管道(銀行借貸管道)兩種。在本文中,擬從狹義的信用觀點出發,探討不同金融機構是否存在銀行借貸管道。 在本文對信用管道的研究中,我們有別以往以向量自我迴歸模型(VAR模型)、結構化向量自我迴歸模型(SVAR模型)、或將資料一階差分進行一般最小平方法(OLS法)實證研究分析,我們從資料的原始值出發並探討變數之共整合關係(Cointegration),並利用完全修正最小平方法(FMOLS法)對迴歸式進行係數之估計,探討貨幣政策變動下,不同銀行,包括一般銀行、中小企銀、及基層金融機構(農漁會信用部與信用合作社)之放款對於貨幣政策的反應,探討信用管道是否存在於台灣的事實。
