dc.description.abstract (摘要) | 本研究在資產報酬率之波動具有緩長記憶(long memory)的部分整合指數廣義自迴歸條件異質變異數(fractionally integrated exponential generalized autoregressive conditional heteroskedasticity;簡稱FIEGARCH)模型下,配合極端值理論(extreme value theory)計算風險值(value at risk)。本研究以新台幣兌美元匯率為例,實證結果發現其日報酬率之波動具有緩長記憶現象,且FIEGARCH模型配合極端值理論之風險值計算法的表現較為穩定。 | - |
dc.description.abstract (摘要) | In this paper, we use the FIEGARCH model combined with extreme value theory to compute Value at Risk (VaR) measure for daily asset returns. Our empirical example in using TWD/USD exchange rate returns shows that the data reveal long memory phenomenon and the FIEGARCH model combined with extreme value theory provides a good representation in VaR estimation framework. | - |
