多元资本网络:理论框架的构建

企业价值创造来源于财务资本与非财务因素的耦合,而该耦合机理的研究,则演变为对于多元化的资本网络的框架研究,因此多元资本网络的形成机理、演化规律和治理机制构成了本论文的研究主题。本研究认为资本网络是结构性地嵌入在企业网络和企业价值网络中,其演化是通过多元资本结构和资本转换来实现的,多元资本结构影响企业价值创造,资本转换实现企业价值创造。多元资本网络的治理则是传统科层治理和网络治理的有效融合,本论文还提出了多元资本网络治理中控制权相机配置的理论框架。     

辗辊式井下采油筛管的研制及应用

针对油田在用井下采油筛管防砂过程中出现的砂堵等问题,依据能量转换原理,研制出一种辗辊式井下采油筛管。辗辊式筛管既防砂又不发生砂堵,还具有穿透性和节能效果明显等特点,不仅可用于一般的采油井、含砂量大和压裂的井,还可用于污水泵的保护。     

Post-SARS tourist arrival recovery patterns: An analysis based on a catastrophe theory

In 2003, the Severe Acute Respiratory Syndrome (SARS) ravaged many Asian countries. The outbreak of SARS caused a crisis in the tourism industry in many parts of Asia in that year. The purpose of this study is to examine and to compare the post-SARS recovery patterns of inbound arrivals from Japan, Hong Kong and USA in Taiwan. Taking the cusp catastrophe model as its foundation, this study proposes a well-grounded approach to understanding the nature of the recovery processes and to explaining the difference between the recovery patterns displayed by arrivals from Japan and those from Hong Kong and USA. Implications regarding tourism promotion policies are drawn from the analysis.     

流动性平衡、价值创造及金融产品设计原则——基于符号经济系统和实体经济系统互动的视角

本文运用含有实际余额效应的瓦尔拉斯模型描述了符号经济系统与实体经济系统的基本平衡条件,并指出流动性(信用)是通过影响价值创造过程而间接地创造价值,但流动性的过度扩张可能导致符号经济系统独立于实体经济运行而与价值创造无涉,打破两系统的基本平衡关系。本文最后通过对美国新金融模式的分析,说明我们仍需按照资金转移及分配和风险转移及分配两种基本中介功能相分隔的原则来设计金融产品,才能避免信用过度扩张而导致的流动性危机。     

Corporate Risk Management under Information Asymmetry

This paper examines the financial and operational hedging activities of US pharmaceutical and biotech firms that are subject to a high level of information asymmetry stemming from R&D investments during 2001–2006. We find evidence in support of the information asymmetry hypothesis à la Froot, Scharfstein and Stein (1993) that hedging helps mitigate the under‐investment problem. Specifically, we find that the use of financial derivatives is associated with greater firm value and that the value enhancement is larger for firms subject to greater information asymmetry and better growth opportunities. There is a synergy between financial hedging and operational hedging where the latter is used to counter product development risk. The results are robust with respect to alternative performance measures, industry‐specific growth measures, and the endogeneity problem. Our work is differentiated from existing studies that examined commodity‐based industries without addressing information asymmetry.

Why firms issue callable bonds: Hedging investment uncertainty

This paper analyzes a firm's dynamic decisions: i) whether to issue a callable or non-callable bond; ii) when to call the callable bond; and iii) whether to refund it when it is called. We argue that a firm uses a callable bond to reduce the risk-shifting problem in case its investment opportunities become poor. Our empirical findings support this argument. We find that a firm facing poorer future investment opportunities is more likely to issue a callable bond than a firm facing better investment opportunities. In addition, a firm with a higher leverage ratio and higher investment risk is more likely to issue a callable bond. Finally, after a callable bond is issued, a firm with a poor performance and a low investment activity tends to call back a bond without refunding; a firm with the best performance and highest investment activity tends to call back a bond and refund its call; and a firm with mediocre performance and investment activity tends to not call its bonds.
