A theoretical framework to evaluate different margin‐setting methodologies

The margin system is the first line of defense against the default risk of a clearinghouse. From the perspectives of a clearinghouse, the utmost concern is to have a prudential system to control the default exposure. Once the level of prudentiality is set, the next concern will be the opportunity cost of the investors, because high opportunity cost discourages people from hedging futures, and thus defeats the function of a futures market. In this article, we first develop different measures of prudentiality and opportunity cost. We then formulate a statistical framework to evaluate different margin‐setting methodologies, all of which strike a balance between prudentiality and opportunity cost. Three margin‐setting methodologies, namely, (1) using simple moving averages; (2) using exponentially weighted moving averages; (3) using a GARCH approach, are applied to the Hang Seng Index futures. Keeping the same prudentiality level, it is shown that the one using a GARCH approach by and large gives the lowest average overcharge. © 2004 Wiley Periodicals, Inc.

The index futures markets: Is screen trading more efficient?

This article uses a nonparametric test based on the arc‐sine law (see, e.g., Feller, 1965 ), which involves comparing the theoretical distribution implied by an intraday random walk with the empirical frequency distribution of the daily high/low times, in order to address the question of whether the abandonment of pit trading has been associated with greater market efficiency. If market inefficiencies result from flaws in the market microstructure of pit trading, they ought to have been eliminated by the introduction of screen trading. If, on the other hand, the inefficiencies are a reflection of investor psychology, they are likely to have survived, unaffected by the changeover. We focus here on four cases. Both the FTSE‐100 and CAC‐40 index futures contracts were originally traded by open outcry and have moved over to electronic trading in recent years, so that we are able to compare pricing behavior before and after the changeover. The equivalent contracts in Germany and Korea, on the other hand, have been traded electronically ever since their inception. Our results overwhelmingly reject the random‐walk hypothesis both for open‐outcry and electronic‐trading data sets, suggesting there has been no increase in efficiency as a result of the introduction of screen trading. One possible explanation consistent with our results would be that the index futures market is characterized by intraday overreaction. © 2004 Wiley Periodicals, Inc.

How similar is the world in the internet era? A comparison of e‐business in China,Russia, and Sweden

Much has been written about how e‐business can serve as a strong homogenizing influence and essentially make the world into one market. Yet, little research has empirically investigated this question. This study seeks to describe e‐business activity in China, Sweden, and Russia to identify similarities and differences in the portfolios of e‐business applications in these countries. Our results indicate that different e‐business applications are emerging as more prevalent in different countries. © 2006 Wiley Periodicals, Inc.     

Trends in international business thought and literature: Parallels between the east and the west: The teachings of ancient Chinese philosophers and the echoes from western management theorists

This article aims to bridge the gap between an oriental culture and a western approach to management concepts and practice with a view to exploring a culturally fit style of management for China. Comparisons are drawn between the teachings of early Chinese philosophers and scholars with those of their western counterparts. It is envisaged that hidden links may be eventually found so that management as a universal concept with cultural variations may be the trend in the nineties and beyond.     

Confucian Business Ethics and the Economy

Confucian ethics as applied to the study of business ethics often relate to the micro consideration of personal ethics and the character of a virtuous person. Actually, Confucius and his school have much to say about the morals of the public administration and the market institutions in a more macro level. While Weber emphasizes the role of culture on the development of the economy, and Marx the determining influence of the material base on ideology, we see an interaction between culture – specifically Confucian business ethics – and the economy. In this paper, we are going to study this interaction in several crucial stages of development of Confucianism. The paper concludes by postulating the relevance of Confucian business ethics to the global knowledge economy.

Do executive stock option grants have value implications for firm performance?

Consistent with predictions of agency theory, we find direct evidence that executive stock option grants have value implications for firm performance. This inference is drawn from evaluation of various motivations for the use of such grants in executive compensation: value enhancement, risk taking, tax benefit, signaling and cash conservation. We find consistent evidence for the value enhancement motivation to reduce agency costs. As well, they signal for positive price sensitive information. Our results reject the tax benefit and cash conservation motivations. This finding is robust after controlling for the endogenous character of executive stock option grants and other equity-based grants. JEL Classification G32 • J33 • M52
