Cointegration and Tests of Purchasing Power Parity

Cointegration and Tests of Purchasing Power Parity
摘要
如果PPP成立,來自及其匯率、國內外的物價水準的線性組合的誤差應該要是定態。
如果實質匯率是定態,則長期絕對購買力平價理論有效。
基本理論
PPP理論認為均衡匯率應由兩國通貨水準之相對購買力平價決定,而購買力可用物價水準來衡量,即基於單一價格法則,在無運輸成本、交易成本和關稅及非關稅貿易障礙的假設下的理論。
本篇報告分為五個部分:
1. 摘要
2. 需要的資料
3. ADF、PP單根檢定(Phillips and Perron unit roots test)、共整合檢定 (Engle and Granger test)、Von Neumann Ratio.
4. 結論
5. 未來如何去做:
需要的統計數據
Data and Period : The data are monthly averages of daily and beginning July 1973 and ending September 1986.
主要實證結果
使用ADF和PP檢定,我們無法去拒絕一個單根的虛無假設對實質的匯率,因此,長期的絕對PPP被拒絕。
如果我們解釋共整合為一個長期均衡關係的證明,然而這文章的發現建議在長期之下可能會偏離
困難處或遭遇之問題
對於Von Neumann Ratio還沒有到很熟悉的了解、和實際操作,所以一開始有很大的疑惑。
在文章中對於Von Neumann Ratio內容定義沒有解釋的很清楚,眾多檢定方法之間似乎都有相關性,還無法整理出大架構。

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.
