| Abstract: | 這篇論文主要探討的是現任央行總裁彭淮南上任後，央行對於匯率管理上的政策行為。
我們觀察從19991年到2009年這段期間的名目有效匯率發現，雖然匯率波動於一個區間之內，
但名目有效匯率在大部份的期間都是被低估的，尤其是近幾年來更是相當的偏低。
所以我們懷疑臺灣央行所管制的匯率目標區他們較希望能維持新臺幣在被低估的水準，當新臺幣匯率受到高估時，央行則希望能將其下修。
為了探討這個情況，我們透過Krugman(1991)所發表的匯率目標區模型來試著得到新臺幣的最適匯率行為。又因為臺灣的特殊經濟背景，
我們融合了Chen，Funke和Glanemann(2009)的寬鬆邊界匯率目標區模型和Torres(2000)的隨機邊界內的央行干預模式來修正傳統的Krugman模型。
然而，傳統的Krugman模型我們得到最重要的結論是，當匯率越接近上下邊界時會有越強烈的蜜月效果，也就是說匯率的波動越平緩。
但是當我們融入上面兩種修正在配合新臺幣的名目有效匯率實際資料時，我們發現蜜月效果僅僅存在於下界，就算是央行所保護的區間有變動時，
在下界還是相對於上界穩定相當多。這就是因為在下界存在著強烈的蜜月效果，所以匯率在越接近下界時會越穩定，甚至有很大機率維持在下界附近。
這個結論跟我們觀察實際資料所發現的現象是相當符合的，所以能夠解釋為什麼新臺幣的名目有效匯率會總是被低估。
This paper discusses the policy rule used by Central Bank of the Republic of China(Taiwan) with target zone to the exchange rate dynamics. We focus on the recent phenomena on the exchange rate of NTD, and try to figure why the NEER of NTD is always underestimated. Due to the regime of Central Bank of the Republic of China(Taiwan), we combine two extensions into the basic Krugman(1991) target zone model which are Chen, Funke and Glanemann`s soft edge target zone model(2009) and Torres`s stochastic intra-marginal intervention pattern. And we estimate the parameters with
simulated method of moments(SMM). By this two extensions, we conclude that there is strong honeymoon effect to the exchange rates at the lower bound, but the honeymoon effect is very weak at the upper bound. This conclusion is matched with the empirical data, and explains why the NEER of NTD is always underestimated. |
