In the knowledge economy era, a firm¡¦s competitive edge increasingly depends on the possession of knowledge and intellectual capital. Knowledge becomes the key resource for firms, and firms must increase the attention they pay to knowledge management. A very important issue regarding intra-firm knowledge transfer is to identify the model and circumstances in which knowledge can effectively be transferred. The objective of this study is to demonstrate the typology of intra-firm knowledge transfer executed by different semiconductor firms. Multiple case study approach is adopted to identify the pattern of knowledge and technology transfer in this study. In order to analyses knowledge transfer activities, four semiconductor firms were studied with qualitative method. Multiple sources of evidence are gathered, including documents, interviews, and internal reports. Synthesizing the knowledge transfer practices of these firms, this study demonstrates three models for intra-firm knowledge transfer. These knowledge transfer models have important implications for technology and knowledge management. First, deploying these transfer models, replication strategies can apply to the manufacturing sector, including high-tech firms. Manufacturing firms can transfer manufacturing processes between business units and achieve synergy effects or performance consistency. Second, these transfer models validate the contingency theory since various situations induce different transfer models. Third, from these cases we can understand that external benchmarking may not always be the best way to solve problems and maintain competitive advantage. Resource-based theory maintains that firms can retain competitive edge by efficiently and effectively applying practices developed in-house.

券商和投資大眾越來越了解價格風險管理的重要性，但是對於波動度風險管理工具及其重要性的認知卻較為貧乏。論文探討的即是美歐新興的波動度管理工具：波動度交換契約(volatility swaps)和變異數交換契約(variance swaps)。藉著波動度交換契約，交易者就可以將所暴露的不確定風險轉換為固定的風險。 論文的焦點在於變異數交換契約(variance swaps)公平履約價的訂定。文章中所使用的評價方法是複製法(replictions strategy)，在唯一的假設條件下：股價的變動是連續的，用已知的金融商品複製成新的商品，而複製成本也就是變異數交換契約的公平價格。 在完美的市場中，我們用履約價從零到無限大的選擇權複製變異數交換契約，但是現實的情況下並不允許如此，改用有限範圍的選擇權複製其損益。故再加以討論當假設不成立：股價跳空時，以及用有限範圍履約價對複製策略的影響。 而波動度交換契約(volaility swaps)不管在理論上或是實務上的評價、避險的難度都遠高於變異數交換契約，在第七章節中，引用泰勒展開式和Heston的波動度模型，求得波動度交換契約公平履約價Kvol的評價公式。 一、中文部分： 1.、 寶來金融創新雙月刊 p31-p38 ‘波動性風險可以規避嗎？’ 陳凌鶴、林瑞瑤 2 、國際金融市場泛論與分析 陳松男著 3 、選擇權與期貨：衍生性商品 陳松男著 4 、期貨市場分析 朱浩民著 二、英文部分： 1.
