本篇文章設計一個價格具僵固性 (stickiness) 之不完全競爭市場的貨幣經濟體系,且消費受限於所持有貨幣餘額的想法,建立一般化的模型。同時考慮不完全競爭市場及貨幣面因素,並於政府預算平衡的前提,探討政府採取通貨膨脹的穩定政策而釘住特定的通貨膨脹率時,對相關總體經濟變數和經濟成長率的影響。研究所得之主要結論為,中央銀行利用通貨膨脹目標法則執行通貨膨脹目標政策時,必須先清楚的了解體系內的經濟結構,使得中央銀行政策變動時可幫助民眾了解到未來通貨膨脹的變化,迅速調整對物價的預期,進而達成物價穩定與充分就業的目的,對於中央銀行來說可以消除對於未來物價水準的不確定性。反之,若中央銀行對於經濟體系結構不清楚明瞭的話,中央銀行執行通貨膨脹目標政策欲逹成政策目標時,反而會造成不確定性的經濟影響。 This is paper use inflation targeting as monetary policy to control money growth rule in a cash-in-advance economy with capital under imperfect competition. We present analytical results showing that, when the central authorities understand economy framework to use inflation targeting as monetary policy can increase economy’s growth rate and stable price level. On the other hand, when the central authorities do not understand economy framework to use inflation targeting as monetary policy can result in real indeterminacy.
