The Wealth Effect of Domestic Joint Ventures: Evidence from Taiwan

This study presents important international evidence by examining the wealth effect of domestic joint ventures by Taiwanese firms. In opposite to United States evidence, we find that announcements of domestic joint ventures by Taiwanese firms are, on average, associated with significantly negative abnormal stock returns. We also find that the stock market response to announced domestic joint ventures is significantly positively related to the announcing firms' investment opportunities, size of investment and debt ratio, and is significantly negatively related to the business relatedness variable. In contrast, free cash flow, firm size, relative firm size and managerial ownership are found to have no significant power in explaining the market response. Our results support the investment opportunities, synergy and complementarity hypotheses as well as a broad interpretation of the free cash flow hypothesis, but reject the absolute size, relative size and alignment-of-interests hypotheses. This study makes valuable contributions to the literature by providing the first direct evidence on the role of investment opportunities, synergy and alignment-of-interests in explaining the wealth effect of domestic joint ventures     

纳税人诉讼基本问题探讨

美国、英国、日本等发达国享均建立纳税人诉讼制度，事实证明，纳税人诉讼制度对于监督政府征税和使用税收均发挥了重大的作用。作为社会主义国家的中国能否建立纳税人诉讼制度以及应该怎样建立一套适合中国的纳税人诉讼制度是摆在我们面前需要解决的一个重要问题。     

电力标准化需要重点解决的两个问题

电力标准化--存在问题与扩展空间 一、搞好标准化需要一个机构 为了加强对企业标准化工作的领导,国家技术监督局于1990年以第13号令的形式发布了<企业标准化管理办法>,其中第21条要求"企业根据生产、经营需要设置标准化工作机构,配备专、兼职标准化人员,负责管理企业标准化工作",同时还规定了该机构、人员的任务.这个办法虽然发布较早,但是其中的绝大部分要求都对今天电力企业开展标准化工作具有重要的规范与指导作用,并不过时.     

一个培育我国外贸新增长点的设想--发展环渤海区域外贸城市群

对外贸易的拉动作用是实现我国十六大经济增长目标的重要保证。但是，反观当前的国内外环境，我国进出口贸易的发展遇到了诸多困难。欲解决这些问题，必须进行制度创新，其中培育城市群是一种可行的办法。而环渤海区域以其特有优势，成为培育对外贸易城市群的首选。为此，我国需要在环渤海区域大力发展高新技术产业，培育产业集群，引导民营企业发展，以及发挥政府的政策作用。     

荷兰：领军欧洲物流

就像性格决定命运一样,一个国家所处的地理位置常常决定了这个国家的内在气质和发展命运。荷兰作为欧洲门户的战略位置必然决定了它开放、自由、灵活、新鲜、充满理想的性格特征。而事过境迁之后的今天,这个国家依然以蔑视常规、热衷冒险,野心勃勃的心态努力开创新世界。

An empirical analysis of the relationship between the hedge ratio and hedging horizon: A simultaneous estimation of the short‐ and long‐run hedge ratios

This article analyzes the effects of the length of hedging horizon on the optimal hedge ratio and hedging effectiveness using 9 different hedging horizons and 25 different commodities. We discuss the concept of short‐ and long‐run hedge ratios and propose a technique to simultaneously estimate them. The empirical results indicate that the short‐run hedge ratios are significantly less than 1 and increase with the length of hedging horizon. We also find that hedging effectiveness increases with the length of hedging horizon. However, the long‐run hedge ratio is found to be close to the naïve hedge ratio of unity. This implies that, if the hedging horizon is long, then the naïve hedge ratio is close to the optimum hedge ratio. © 2004 Wiley Periodicals, Inc. Jrl Fut Mark 24:359–386, 2004     

QUADRATIC TERM STRUCTURE MODELS FOR RISK-FREE AND DEFAULTABLE RATES

In this paper, quadratic term structure models (QTSMs) are analyzed and characterized in a general Markovian setting. The primary motivation for this work is to find a useful extension of the traditional QTSM, which is based on an Ornstein–Uhlenbeck (OU) state process, while maintaining the analytical tractability of the model. To accomplish this, the class of quadratic processes, consisting of those Markov state processes that yield QTSM, is introduced. The main result states that OU processes are the only conservative quadratic processes. In general, however, a quadratic potential can be added to allow QTSMs to model default risk. It is further shown that the exponent functions that are inherent in the definition of the quadratic property can be determined by a system of Riccati equations with a unique admissible parameter set. The implications of these results for modeling the term structure of risk-free and defaultable rates are discussed.
