Long Memory Features Evolve in the Time-varying Process in Asia-pacific Foreign Exchange Markets

Abstract
We investigated the presence of, and changes in, long memory features in the returns and volatility dynamics of six Asia-Pacific foreign exchange markets (Australian dollar, Japanese yen, Korean won, New Zealand dollar, Singaporean dollar, and Taiwan dollar) using time-varying Hurst exponents. In particular, instead of relying on a single static measure of long memory, we explored time-varying long memory features over time to assess changes in market efficiency by analyzing the returns and volatility of the markets. Furthermore, considering a time-varying rolling approach, we estimated values of the Hurst exponent for time windows with 1,000 observations (about 4 years of data) in each window. The estimation results indicated that both the returns and the volatility series possessed strong long memory features and that the degree of the long memory features changed over time. Additionally, the Hurst exponent showed an upward trend during the 1997 Asian currency crisis and 2008 global financial crisis, indicating that exchange rate markets became inefficient and predictable during the financial crisis.

PO 文注意事項 (Notes about your posts required for this course)

每位同學必需建立與維護 2 個網頁: (updated on 2010.9.19)
Every registered student MUST post and maintain TWO pages at this site.

1. 你的期末報告想要仿照的原始 paper 重點摘要頁, 見 [範例]
A summary of the paper you choose to follow in your term-project. (see a suggestive [summary example ]).

2. 你的學習紀錄頁, 見 [範例]
A "learning weblog" of your progress during this course (see [example]). This example is demonstrative rather than required to conform to.

3. 記得每一頁要在頁尾處輸入你的「標籤」, 包含學號後5碼, 名字或暱稱, 和 其它你自訂的關鍵字, 例 ADF、共整合、PPP、等
When you edit your pages, be sure to write appropriate "Tags" (as many as you wish) (around the bottom of editing screen) for your posted pages to let me identify your required contributions. The tags should at least include your last 5-digit student ID and keywords about the page.

4. 請同學在你所選的 paper 加上標籤:「已選」
If you have already decided a paper to follow and post a page for it. Please be sure to attach that page a specific tag named "selected or 已選." It is of course possible that two or more students may choose the same paper to follow as their term-project. BUT only one of them can be authorized to follow the specific paper. The decision will be based on a first-come-first-serve rule. That is, the one who posts the summary page of a paper gets the first priority to follow that paper posted with a tag named"selected" paper .

5. 在你的 學習紀錄頁加上標籤:「學習記事」
Don't forget to stick a tag "weblog" with your "learning weblog" page in addition to your last 5-digit student ID.
