無風險利率平價說之檢定--台灣的實證研究

林意萍 Unknown Date (has links)
我國自1979年2月1日成立外匯市場,實施浮動匯率制度,1987年7月15日解除大部份外匯管制,1989年4月3日進一步廢止中心匯率制度,實施外匯交易自由化,1991年11月央行公佈重開遠匯市場的遠期外匯買賣辦法,遠期外匯市場再度放,及近來致力發展台灣成為區域金融中心,陸績採行多項金融自由化與國際化的措施,使得國際間的資本移動愈趨活絡,卻也增加了匯率波動的風險(exchange rate risk),因此有必要在遠期外匯市場上操作以規避匯率波動的風險。 Frenkel(1992)曾提出無風險利率平價均衡(covered interest rate parity,簡稱CIP)可以反應國際間資本移動性的大小。鑑於國內過去文獻研究的樣本期間並未涵蓋晚近解除外匯管制措施後的時期,而這些管制的解除會促進國際間的資本移動,影響CIP的檢定結果,因此有必要對無風險利率平價說再做探討,以了解金融環境的日趨開放、資本移動限制放寬對無風險利率平價的影響。 由於台灣資金的匯進與匯出主要是以美元做為媒介通貨(vehicle currency),此外由於美國本身對國際資本移動的限制很少,不同期間CIP檢定的差異較能反應台灣資本管制程度的變動,因此選擇以美國和台灣的匯率及利率資料來檢定CIP。遠期外匯市場在1989年4月至1991年10月關閉,沒有遠期匯率的掛牌交易資料,故本文實證分析將期間分成兩段,分別估計,並檢視政策開放措施對無風險利率平價的影響。 另外為改進過去文獻在計量方法上的缺失,本文以單根檢定和共整合分析的概念從事CIP實証檢定分析。我們的實證結果發現第一段期間並不接受弱式及強式的無風險利率平價,第二段期間弱式及強式的無風險利率平價在5%的顯著水準值下則被接受,而觀察台灣的資本管制措施發現,在第一段期間管制較為嚴格,第二段期間則較為寬鬆。

台灣股票市場的長期超額報酬與股票風險溢酬值 / The Equity Excess Return and Risk Premium of Taiwan Stock Market

簡瑞璞, Chien, Dennis Jui-Pu Unknown Date (has links)
已實現投資報酬率與無風險利率之差、被稱為超額報酬,而股票的預期報酬率超過無風險利率的部份則為股票風險溢酬,是許多資產評價模型的重要依據,例如資本資產定價模型。有不同的理論架構解釋說明風險溢酬值,例如;股票風險溢酬的迷思、短期損失的憎惡、生還存留因素和回歸與偏離平均值等等。 研究台灣股市的超額報酬與股票風險溢酬,有助投資大眾和企業理性面對股市的預期報酬和風險,對台股才有合理的期望報酬值。分析1967年迄2003年的台灣金融市場,計算過去37年長期的幾何平均年報酬率,以臺灣證券交易所發行量加權股價指數為台股市場報酬率,已實現台股實質年報酬率為6.71%。無風險報酬率使用第一銀行的一年期定期存款利率,實質台幣存款年利率為3.07%,消費者物價指數年增率則為4.80%。以年資料計算的台股實質超額報酬,算術和幾何值分別為12.48%和3.63%(年),計算月資料算術平均和幾何平均值分別為0.77%和0.25%(月)。過去37年長期的台股超額報酬現象未較歐美市場的情況更加明顯,也比一般市場的預期報酬率低。 因資料取得的限制、台股的理論超額報酬方面,1991年迄2003年的近十三年來,經固定股利成長模式和盈餘成長模式的兩種計算方式,台股的實質超額報酬分別為 0.6%和-4.3%,此時期台股的投資報酬率比起台幣存款並不突出、且是低超額報酬。同期的已實現的實質超額報酬值;算術平均1.69%和幾何平均-3.35%。評估目前台股風險溢酬,將十分接近過去37年長期歷史資料得到的超額報酬數值,算術年均值為12.48%(年)和0.77%(月),幾何平均分別為3.63%(年)和0.25%(月),低風險溢酬是當前台灣股票市場的一般現象。 / The difference between the observed historical investment return and the risk-free interest rate is the excess return. The equity risk premium, ERP is the expected rate of return on the aggregate stock market in excess of the rate of risk-free security. ERP is one of important factor of many asset-pricing models, including Capital Asset Pricing Model, CAPM. There were many theories and factors to explain the equity risk premium; equity premium puzzle, myopic loss aversion, survivorship bias, mean reversion & aversion and etc. Studying the value of Taiwan equity excess return and risk premium is fundamental for investors and institutions evaluating the expected market investment return and risk. Analyzing the data from year 1967 to 2003 for thirty-seven years long holding period, Taiwan Stock Exchange Capitalization Weighted Stock Index as Taiwan stock market return, the realized real return was 6.71%. One-year bank time deposit rate as NT dollars risk-free asset rate and real interest rate was 3.07% and consumer price index, CPI annual growth rate was 4.80%. The historical real yearly excess return was 12.45% for arithmetic mean and 3.63% geometric mean; the historical real monthly excess return was 0.77% for arithmetic mean and 0.25% geometric mean. Taiwan realized equity excess returns were not higher than the returns in the developed countries and were also lower than the market's expectation. Due to the limits of available data, the theoretical equity excess returns that were calculated on two theoretical models; Constant Growth Dividend Discount Model (dividend yield model) and earnings yield model were 0.6% and -4.3% from year 1991 to year 2003. Comparing the same period of historical realized excess returns of 1.69% for arithmetic mean and -3.35% geometric mean, Taiwan stock market returns were not spectacular. The current equity risk premium of Taiwan stock market is low and should be near the level of the long historical realized equity excess return.
