匯率變動對台灣國際收支之影響

劉瑞垣, LIU, RUI-YUAN Unknown Date (has links)
國際收支理論的分析,共有三個學派,而晚近發展的貨幣學派,深為一般學者專家的 重視與探討,此學派認為國際收支是一種貨幣現象,國際收支的不均衡即反應於國內 貨幣市場的不均衡,因此國際收支的失衡與調整,必須以貨幣為分析中心。當由於國 際收支斥字而採行貶值政策時,產生直接支出效果,降低國內支出水準,出口增加, 進口減少,外匯增加,短期間國際收支改善,但外匯增加,貨幣供給量亦增加,在貨 幣需求不變的情況下,長期間貨幣市場又恢復均衡,國際收支平衡,貶值政策無效。 台灣過去二十餘年來,常以匯率政策作為調整國際收支的手段,從台灣的經濟發展過 程與各項經濟統計資料分析,台灣外貿依存度高,易受世界經濟變動的衝擊,頗能符 合貨幣派所主張的小型開放經濟模型,因此本文乃從貨幣學派的理論模型來分析匯率 政策的國際收支效果。 全文共分為六章,第一章為緒論,第二章對貨幣派貶值政策效果的分析與主張作一檢 閱,第三章為將各國經濟學者對貶值政策效果的實證。研究加以綜合分析,第四章依 經濟統計資料,分析台灣的經濟背景,第五章從貨幣市場依貨幣分析法的理論觀點, 採直接迴歸法與殘差檢驗法來驗證台灣六十二年二月、六十七年七月及七十年八月三 次匯率政策對台灣國際收支的效果,第六章為結論。

X bar-S square區域管制圖的最適設計 / The Optimal Design of X bar-S Square Zone Control Charts

陳智鴻, Chen, Chih-Hon Unknown Date (has links)
自Duncan在1956年提出管制圖的經濟設計以來,陸續有許多學者提出各種不同型態管制圖的經濟設計,但是在這些文章中,尚無將描點的連串檢定列入考慮者,然而在管制圖中加入描點的連串檢定實有其必要性,加入描點的連串檢定可增加管制圖的偵測能力,但是這種作法頗為麻煩,因此Jaehn(1987)提出了區域管制圖來取代傳統管制圖加上連串檢定的不便,本研究提出X Bar-S Square 區域管制圖的經濟設計以改善一般經濟管制圖未將描點的連串檢定列入考慮的缺點.我們以製程中各項製程和成本資料為因子,對經濟區域管制圖的最佳設計參數值做敏感度分析,以找出製程中的關鍵參數.另外我們應用Saniga(1989)經濟統計管制圖的觀念設計經濟統計區域管制圖.雖然經濟統計區域管制圖所計算出的成本會比經濟區域管制圖稍大,但是在統計表現上卻符合我們的要求.

最小成本下,規格及X-bar-S管制圖之設計 / The design of specification and X-bar-S charts with minimal cost

沈依潔, Shen, I Chieh Unknown Date (has links)
最小成本下,規格及X-bar-S管制圖之設計 / The design of economic statistical control charts and specification are both crucial research areas in industry. Furthermore, the determination of consumer and producer specifications is important to producer. In this study, we consider eight cost models including the consumer loss function and/or the producer loss function with the economic statistical X-bar and S charts or Shewhart-type economic X-bar and S charts. To determine the design parameters of the X-bar and S charts and consumer tolerance and/or producer tolerance, we using the Genetic Algorithm to minimizing expected cost per unit time. In the comparison of examples and sensitivity analyses, we found that the optimal design parameters of the Shewhart-type economic X-bar and S charts are similar to those of economic statistical X-bar and S control charts, and the expected cost per unit time may lower than the actual cost per unit time when the cost model only considering consumer loss or producer loss. When considering both consumer and producer tolerances in the cost model, the design parameters of the economic X-bar and S charts are not sensitive to the cost models. If the producer tolerance is smaller than the consumer tolerance, and the producer loss is smaller than the consumer loss, the optimal producer tolerance should be small.
