    台灣對外貿易依存度高,而匯率在國際貿易活動中,又一值扮演著重要的角色,在未來市場面臨國際化、自由化,以及我國加入WTO的趨勢下,面對匯率風險乃是在所難免,所以本研究是以美元兌換國際間主要貨幣之即期匯率,包括有加拿大幣、英鎊、德國馬克、法國法郎、日圓和台幣為實證對象,評估不同模型估計出的風險值與預測績效。模型分為有母數模型與無母數模型兩大類。有母數模型假設資產報酬率為隨機、獨立之常態分配且序列不相關,分別包含了均等權數移動平均法、RiskMetric模型及含有異質變異的GARCH模型;無母數模型對於資產報酬並不假設任何分配,主要是透過歷史資料模擬而得,分別包含了歷史模擬法及蒙地卡羅模擬法。此外,本研究為了探討風險值間具有自我相關(autocorrelated)的特性,也更進一步的加入了Engle and Manganelli (2000) 提出的條件自我相關VaR模型 - CAViaR, CAViaR是將傳統衡量出風險值具有跳躍的情況予以平滑化(smoothly),亦即表示風險值間具有前後期的自我相關性。
    本研究得到的結論為,以成功率來比較各模型,在短期平均而言,以蒙地卡羅模擬法最佳,中長期而言以RiskMetric較適;以均方差標準根來比較,RiskMetric所計算出的風險值相較於實際發生損失值間的差距較小,對於中長期風險值的估計,必須考量異質變異的情況下,CAViaR相較於其他傳統模型所估計出來的風險值之RMSE值較小,為值得考慮的較佳模型。本研究建議,投資人或金融機構要進行各外幣的短期投資以RiskMetric模型及5%的顯著水準來衡量風險值最佳,若進行中長期投資,在不考慮異質變異的情況下,建議以歷史模擬法為估計考量,發生異質變異之外幣,則以CAViaR模型較佳。就中央銀行或金融機構將VaR值作為風險控管的角度,在確定的資產持有期間下,本研究建議以歷史資料視窗長度一年(250天)及顯著水準5%的條件下,以Engle and Manganelli(2000)提出的CAViaR模型評估各外幣的風險值最為的恰當,因為CAViaR模型是預估出來的風險值和實際損失值較為接近的模型。
