A Stakeholding Society — What Does It Mean for Business?

The paper describes the differences between stakeholding and shareholding views of the objects of business. In the former, the object of business is to develop good businesses. This is defined by the criteria normally associated with good businesses and valued by good businessmen themselves—satisfying customers, developing the skills and motivation of employees, earning good returns for investors. In the latter, profit is the defining purpose of business; and other objectives, although often pursued, are purely instrumental to that end. By emphasising the difference between a characteristic of an organisation— behaviour that is developed and valued for its own sake—and the policy of an organisation—behaviour that is adoped for the time being because of its hoped for consequences—I explain the greater capacity of the stakeholding company to make commitments in implicit contracts with all stakeholders. For this reason, it may perform better for all stakeholders, including shareholders.     

Agility index in the supply chain

To achieve a competitive edge in the rapidly changing business environment, companies must align with suppliers and customers to streamline operations, as well as working together to achieve a level of agility beyond individual companies. Consequently, agile supply chains are the dominant competitive vehicles. Embracing agile supply chain requires asking some important questions, namely: what exactly is agility and how can it be measured? Moreover, how can agility be effectively achieved and enhanced? Due to the ambiguity of agility assessment, most measures are described subjectively using linguistic terms. Thus, this study develops a fuzzy agility index (FAI) based on agility providers using fuzzy logic. The FAI comprises attribute’ ratings and corresponding weights, and is aggregated by a fuzzy weighted average. To illustrate the efficacy of the method, this study also evaluates the supply chain agility of a Taiwanese company. This evaluation demonstrates that the method can provide analysts with more informative and reliable information for decision.     

Population Density and Infrastructure Development

A model is proposed with the following features: (1) there is a publicly accessible transport technology, which is more advanced when there is more specialized labor in it; (2) a high population density facilitates the development of the transport technology; (3) an improved transport technology facilitates a finer division of labor, which in turn increases per capita income. These features are compatible with the phenomena of economic development described by Boserup in 1981. It is also shown that, provided the infrastructure sector can charge the users, and individuals are free to choose jobs, the competitive equilibrium will be Pareto-optimal.     

A Likelihood Ratio Test of Price Volatilities: Comparing Stock Index Spot and Futures

This paper uses three methods to estimate the price volatility of two stock market indexes and their corresponding futures contracts. The classic variance measure of volatility is supplemented with two newer measures, derived from the Garman-Klass and Ball-Torous estimators. A likelihood ratio test is used to compare the classic variance measure of price volatilities of two stock market indexes and their corresponding futures contracts during the bull market of the 1980s. The stock market volatilities of the Standard & Poor's 500 (S&P 500) and New York Stock Exchange (NYSE) indexes were found to be significantly lower than their respective futures price volatilities. Since information may flow faster in the futures markets than in the corresponding stock market, our results support Ross's information-volatility hypothesis. It was also noted that the NYSE spot volatility was lower than the S&P 500 spot volatility. If the rate of information flow and firm size are positively related, then the lower NYSE spot volatility is explained by the size effect. The futures price volatilities for the two indexes were insignificantly different from each other. With stock index spot-futures price correlations approaching unity, one implication of our results for index futures activity is that smaller positions in futures contracts may suffice to achieve hedging or arbitrage goals.

工厂自动化物流系统——企业物流技术选型

在制造业中，物流贯穿于工厂生产的各个环节．它们的联系是那样的紧密．甚至已经融入到生产工艺过程之中。无论原材料配送、零部件配送．还是成品酉B送，都需要进行合理的安排，生产过程中的工件和工具的存储、搬运、装卸更需要精密地规划设计。只有合理组织生产物流过程．才有可能使生产过程始终处于最佳状态．避免因物流不畅而导致的生产停顿现象的发生．同时还可以大大缩短生产周期．节约劳动力．提高生产效率．做到柔性化生产．．正是基于这样的认识，我们决定做这个专题。但是当我们用“自动化”这个词来限定专题的范围的时候，其实是很有些犹豫的。因为．就目前而盲．工厂自动化物流系统高投入的特点．足以让很多中国制造企业望而却步。但我们想．这并不妨碍制造企业去了解工厂自动化物流系统的装备特点、应用前景以及供应商的情况。毕竟．自动化是制造业未来的方向。
