貨幣為生產要素之通貨替代模型蔡佩君 Unknown Date (has links)
本文為一採行浮動匯率的小型開放經濟體系,在完全預期的預期模式下,我們設立一代表性個人最適化的通貨替代模型。我們採用的模型是以Liviatan (1981)貨幣進入效用函數的模型為基礎,納入Fisher (1983)視實質貨幣為可節省如勞動、資本等其它生產要素的一種投入要素,而將實質貨幣直接引入生產函數之概念,設立一最適化模型。藉以分析當本國貨幣成長率增加時,對外國貨幣名目存量、本國貨幣實質餘額、實質匯率水準等經濟變數的長期均衡與動態調整行為所產生的影響。本文得到不同於Liviatan (1981)的結果,即長期實質匯率水準會上升,而短期實質匯率水準,則有調整不足、錯向跳動和調整過度等現象。

股票市場與匯率動態理論之研究李秀賢, LI, XIU-XIAN Unknown Date (has links)
自從1973年Bretton Woods 國際貨幣制度崩潰後,各主要工業國家均採行浮動匯
率制度,而各國的匯率水準則呈現劇烈的變動與不安定的現象,如何解釋此一匯率波
動現象。乃成為大家所郤探討的主題。
以往在探討匯率動態的決定理論時,大致可以分為商品對外貿易不均衡時所造成的匯
率動態,以及因某些政府政策或其它外生變數(如國外利率、國外物價等)變動時,
造成資產調整所引起的匯率動態,但是所有的分析均沒有將股票市場考慮進來。但在
最近一年來,我們可以發現股票市場與匯率的波動間有著相互影響的關係存在。而為
了探討此一關係,最近朱美麗、曹天旺(1987)將Blanohard (1981)的模
型擴充為開放體系,來研究貨幣政策及國外利率水準變動時,匯率與股票價格的動態
調整理論。不過,他們的分析止於物價水準固定時的情況,而本文擬進一步分析當物
價水準可以調整的情況下,股票價格與匯率的動態調整。並在此假設下,我們將分別
探討物價調整緩慢與物價調整具有伸縮性的情況下,貨幣政策、財政政策與國外利率
水準變動時所引起的股票價格與匯率的動態調整。
本文的討論共分為五章。第二章先就模型的設立做一詳細的說明。第三章則分析物價
調整緩慢的情況下,各種政策及外生變數變動時的效果及其對體系動態調整的影響。
第四章則分析物價調整具有伸縮性時,各種政策及外生變數變動時的效果及其對體系
動態調整之影響。第五章則為本文的結論。

開放經濟體下納入信用市場之匯率動態 / Exchange Rate Dynamics in a Small Open Economy with Credit Market林育聖, Lin,Yu-Sheng Unknown Date (has links)
In the literature, a considerable theoretical and empirical works have investigated the credit channel of monetary transmission mechanism. This dissertation extends the Bernanke and Blinder (1988) model to an open-economy setting with flexible exchange rate and perfect capital mobility. By means of the framework, we examine the exchange rate dynamics and the adjustment of real output. It turns out that, with a significant credit channel effect, the exchange rate puzzle may occur in the short run and in long run. Moreover, in contrast to Dornbusch (1976), this dissertation shows that, depending upon the strength of the credit channel effect, overshooting, undershooting and counter-shooting impact effect may occur when international capital mobility is perfect. / In the literature, a considerable theoretical and empirical works have investigated the credit channel of monetary transmission mechanism.
