工資調整與外匯干預之分析

陳畊麗 Unknown Date (has links)
早期文獻上有關工資調整與外匯干預的研究,多半獨立進行。近年來,有些學者體認到工資調整與外匯干預其實是相互影響,而非互不關連,方有將兩者結合研究的趨勢。   本文即在探討工資調整與外匯干預政策間的相互影響問題,共分三個部份。第一部份在「同質勞動且資本完全移動」假設下,探討當局最適外我匯干預與最適工資詷整法則的制定以及之間的相互影響。第二部份則建立等損失曲線的概念,重新詮釋第一部份所得的結果。第三部份進一步將“勞動異質”與資本移動程度考慮在內,以了解兩者在當局政策制定上所扮演的角色。茲將本文主要結果摘述如下:   1.政策工具間的相互影響具有不對稱性,需視干擾來源而定。同時,由於政策工具間相互影響的不對稱性,兩政策工具對付各種來源干擾的能力勢將有所不同。在本文架構下,最適外匯干預政策應用於穩定貨幣、國外物價、國外利率干擾,最適工資調整法則應用於穩定實質供給面干擾。   2.「等損失曲線分析」具有兩點特色:第一、以相當對稱的方式解釋當局最適外匯干預與最適工資調整法則的訂定,第二、將當局係依據損失極小化決定最適政策的精神表露無遺。   3.勞動異質對最適政策的影響視干擾來源、勞工團體採用工資指數的情形及當局賦予產出波動的權數而定。其中,就「勞工團體採用工資指數的情形」一項而言,若只有部份蔻力採行工資指數,勞動異質在政策制定上扮演重要角色;但如兩種類型勞工團體採用相同的工資指數,勞動異質將變得較不重要。

我國外匯干預與貨幣政策及匯率變動之相關性分析--訊息傳遞管道

蔡宜靜, Tsai, Yi Ching Unknown Date (has links)
過去文獻探討干預政策影響匯率的管道主要有三個:貨幣管道、資產組合管道與訊息管道。在沖銷干預不改變貨幣基數下,無法透過貨幣管道影響匯率;而過去文獻中對於資產組合管道之實證結果非常不一致,因此,Mussa在1981提出訊息管道認為央行目前的沖銷干預政策可能隱含未來的匯率與貨幣政策進而改變市場參與者的預期而影響目前的匯率水準。 Lewis (1995)使用1985年至1990年美國公開的外匯干預日資料估計一個兩變數的VAR模型,探討干預與貨幣政策之間的關係。同時檢定現在的外匯干預是否隱含未來貨幣政策的改變以及貨幣政策的改變是否引起央行採行逆勢操作的干預政策。Lewis的研究結果顯示,此兩個假設皆成立,表示外匯干預可能預測未來貨幣政策的改變以及貨幣政策的改變也可能使央行進場干預匯率。此外,Lewis也利用衝擊反應函數估計不同貨幣政策變數的衝擊對匯率的影響,發現非借入準備 (nonborrowed reserve) 的衝擊對匯率的影響較M1顯著。 本文參考Lewis的分析架構並且使用台灣資料進行實證分析並進一步估計一個三變數的VAR模型欲探討干預與匯率之直接影響效果。結果發現訊息管道與逆勢操作政策皆存在,且干預對新台幣兌美元的影響較日圓顯著;在貨幣政策變數上,非借入準備對匯率之影響較M1顯著,此結果與Lewis相符。

匯率波動與外匯干預 / Exchange Rate Volatility and Central Bank Intervention

謝柏笙 Unknown Date (has links)
本文章使用 Lin (2010) 的動態追蹤資料分量迴歸(DPQR)來分析匯率波動與外匯干預之間的關係。此外,本文更探討新興市場國家與非新興市場國家樣本間外匯干預對匯率波動的影響。實證結果發現,匯率波動較低時與外匯干預較不具有顯著的正向關係,然而當匯率波動較高時則與外匯干預呈現顯著 的正向關係。此外,在新興市場國家中,可發現在高匯率波動下,外匯干預與匯率波動之間為顯著的正向關係;而非新興市場國家樣本所得到的結果為外匯干預與匯率波動之間在為不顯著的正向關係。

Strategic Trade Policy and Exchange Rate Subsidies: A Study of American Auto Markets

林季陽, Lin,Chi-Yang Unknown Date (has links)
Can intervention by the Bank of Japan on the yen/dollar rates be used as a strategic policy to promote Japanese exports to the U.S. markets? We develop theoretical models based on strategic trade policy literature to explain possible impacts on U.S. automobiles. During the last decade, the changes of yen/dollar rates have coincided with dramatic market-share gains by Japanese automakers in the U.S. market. In the meantime, intervention by the Bank of Japan on the yen/dollar market has reached a record high. Our models assume interventions have two channels to influence U.S./Japan trade. First, we hypothesize that official currency manipulation by the Bank of Japan was implemented as a means to subsidize Japanese. The second channel resulted from the relationship between the expectation of an unavoidable foreign exchange rate appreciation and automobile purchase behavior of U.S. consumers. We assembles the famous “peso problem” in international finance. By preventing the prompt appreciation of JPY using intervention strategy, we argue that intervention by the Bank of Japan create a notion of unavoidable appreciation of JPY rate. This prompts U.S. consumers to purchase cars earlier. We explore the effects of intervention of Bank of Japan on the changes of sale volume and market shares of U.S. and Japan automakers and the results show that the sale volume and market share of American automakers decrease while these of Japanese automakers increase. Empirical results also indicate that U.S. consumers tend to purchase more Japanese automobiles when the Yen’s appreciation is withheld temporary level they have expected. After comparisons, we conclude that interventions by the Bank of Japan affect American automakers through cost disadvantage and Japanese automakers through another channel. Results also imply that the effects of intervention on Japan/U.S. trade lie more through the channel of cost subsidy.
