在全球併購浪潮興起之時,併購活動可能受市場競爭的影響,促使強強合 併,但也可能發生不理性的追隨行為。本文係研究在併購動能中宣告併購,對 主併公司的短期與長期併購績效之影響,並且進一步討論在併購案採現金交易、 主併公司為成長型公司、主併公司過去有成功併購經驗三個條件之下,對主併 公司於併購動能下宣告併購的短期與長期併購績效是否有顯著影響。 本研究之貢獻為,採過去併購績效是否顯著作為併購動能之衡量,而非單 純採用市場上所累積的併購績效之規模。另外,除了探討每個變數與併購績效 之直接關係外,亦特別著重於該變數與主併公司在併購動能中宣告併購之交乘 作用,剖析對主併公司短期及長期併購績效的影響。 而本研究發現,在併購動能當中,若主併公司為成長型公司,能夠顯著提 升其宣告併購之短期與長期績效。因此,對於併購動能下指併公司的績效表現 而言,該公司特性為關鍵因素,特別是對長期的併購績效來說。 / When merger waves occur, the M&A activities may be affected by competitive market. This may cause the win-win cooperation, but also may result in blind following. The primary purpose of this paper is to test the correlation of mergers in momentum and the short-term and long-term merger performance. Furthermore, this paper is also focus on three conditions which may influence the above-mentioned correlation, including cash payment, glamour bidders and bidders’ past successful experience of M&A. The major contribution of this paper is using the significance of past merger performance to measure the merger momentum, instead of simply using accumulated performance. Second, in addition to the direct relation between variables and merger performance, this paper also aims to emphasize the interaction of those variables, analyzing its influence to short-term and long-term performance. It is reported in this paper that, in the merger waves, glamour bidders significantly perofrm better in both short-term and long-term period. Thus, “Glamour” is a key characteristic for the bidders, which would lead to better performance in merger wave, especially long-term one.

本文引用Zhang(1996)和Suen and Yip(2005)提出的貨幣具有降低交易成本的特性，建構封閉經濟體的貨幣內生成長模型，分別探討在投資有或沒有調整成本的情況下，政府採取釘住通貨膨脹目標政策對於經濟成長的影響，以及經濟體系的安定性。 本文的結論可以歸納為：(1)當投資不具有調整成本時，政府調高目標通膨率會使得經濟成長率下降，且經濟體系呈現確定性；(2)當投資調整成本時，政府調高目標通膨率也會使得經濟成長率下降，但經濟體系卻呈現不確定性。 / This thesis sets up a monetary endogenous growth model for a closed economy, in which monetary authorities implement a monetary policy of inflation rate targeting. The main feature of the model is that, in line with Zhang (1996) and Suen and Yip (2005), money plays a role to facilitate transactions of output, and hence holding money can lower the transaction cost. This thesis then uses the model to investigate whether the economy’s growth rate and the dynamic stability are closely related to the implementation of inflation rate targeting. Two main findings emerge from the analysis. First, when investment does not involve adjustment costs, a rise in the inflation rate lowers the balanced economic growth rate and the equilibrium is characterized by local determinacy. Second, when investment involves adjustment costs, a rise in the inflation rate lowers the economic growth rate and the equilibrium is featured with local indeterminacy.
