Futures Trading Activity and Commodity Cash Price Volatility

Abstract:   This paper examines the lead‐lag relationship between futures trading activity (volume and open interest) and cash price volatility for major agricultural commodities. Granger causality tests and generalized forecast error variance decompositions show that an unexpected increase in futures trading volume unidirectionally causes an increase in cash price volatility for most commodities. Likewise, there is a weak causal feedback between open interest and cash price volatility. These findings are generally consistent with the destabilizing effect of futures trading on agricultural commodity markets.

Information flows within and across sectors in Chinese stock markets

We examine the patterns of information flows within and across sectors of the two Chinese stock exchanges in Shanghai and Shenzhen during 1994–2001. Using the generalized forecast error variance decomposition, we find a high degree of interdependence, indicating that the sectors are highly integrated and sector prices reflect information from other sectors. Industry is the most influential sector in both exchanges, while Finance in Shenzhen is the least integrated with other sectors. Implications of the findings for investors and policymakers are also discussed.

战略管理理论在港口企业管理中的应用

近年来,全国各地掀起了港口建设的高潮,投资金额动辄数百亿元,其规划之大、投资之巨,均属空前.然而,巨资建设港口背后的主要力量是地方政府,地方政府这只有形的手在发挥着主力作用,而港口企业并没有真正走向前台,根据企业自身的战略需求来发展企业,在一定程度上出现了"战略迷失".笔者认为,港口企业要实现可持续发展,应当切实关注企业自身的战略.基于此,本文将简要回顾战略管理理论的历史演变,并给出战略管理理论在港口企业中应用的基本模式.     

Collaboration between industry and research institutes/universities on industrial innovation in Beijing, China

Most R&D resources in China were allocated to public research institutes/universities until the economic transition of the mid 1990s. To maximize the return from these resources, it is important to have a healthy collaboration between industry and research institutes/universities on industrial innovation. This paper examines that relationship and discusses some empirical evidence on its efficiency with particular reference to industry in Beijing. Following a survey of 950 industrial enterprises, the influences of the collaboration relationship on industrial innovation were analyzed. The main findings indicate that the technology novelty of industrial innovation is positively related to that relationship, i.e. the more the collaboration, the higher the technology novelty of the innovation. However, the collaboration relationship is less efficient in terms of economic performance indicators such as innovation sales and profit ratios, to measure innovation. Moreover, the collaboration relationship is still far from efficient in stimulating industrial innovation in China. The major barriers to successful collaboration have also been addressed in this paper with the aim of devising policies and suggesting possible improvements to collaboration efficiency.
