We introduce transaction costs into the international capital market to explore the effects of international capital mobility on business cycles. We also compare the fit of the small open economy model with a colsed economy model. We determine the fit of the models in two ways. The first is the traditional method comparing the model's moments with those of the actual economy and the second is the method developed by Watson (1993). Both approaches indicate that, with imperfect international capital mobility, the-small-open economy model can successfully mimic the characteristics of post-war Taiwan business cycles. Furthermore, the technology shock and foreign interest rate shock are the important sources of the post-war Taiwan's business cycles.本文試圖建立一個跨期選擇模型,從小型開放經濟的角度,解釋臺灣景氣循環的特徵。為了檢視國際資本移動程度與臺灣景氣波動之間的關連,在國際資本市場加入交易成本函數,據以描繪不同的國際資本移動程度。結果本文得到,在國際資本不完全移動的假設下,國內技術進步與世界利率衝擊,是解釋臺灣景氣波動的重要衝擊來源,至於政府消費衝擊則由於干擾項之標準差過小,因而影響甚微。本文也對封閉模型與小型開放模型(國際資本完全移動、國際資本不完全移動)的配適度做比較。評估的方法,一為直接比較模型與實際資料的各級動差;另一則是應用Watson(1993)的「Measure of Fit」來評估模型的配適度。結果不論使用何種評估方式,國際資本不完全移動的小型開放模型,對於臺灣景氣波動的解釋能力都最佳。由本文的分析可知,探討臺灣的景氣循環,國外部門應納入考慮,亦即開放經濟較封閉體系更具說服力。再者,國際資本不完全移動的經濟環境是不可忽略的重要因素,而國內技術進步與世界利率變動則是影響臺灣景氣循環的人衝擊來源。159 bytestext/html實質景氣循環小型開放經濟臺灣Real business cyclesSmall open economyTaiwanPost-War Taiwan's Business Cycles: The Small Open Economy and the International Capital Mobility戰後臺灣景氣循環分析:小型開放經濟與國際資本移動journal articlehttp://ntur.lib.ntu.edu.tw/bitstream/246246/282213/1/index.html
