This paper explores the relationship of various trait emotions to the ethical choices of 189 college students who completed
a managerial decision-making task as part of an in-basket exercise in a laboratory setting. Prior research regarding emotion
influences on ethical decision-making and linkages between emotions and cognition informed hypotheses about how different
types of emotions impact ethical choices. Findings supported our expectations that positive and negative emotions classified
as active would be more strongly related to interpersonally-directed ethical choices than to organizationally-directed ones,
and that passive emotions would be less related to ethical choices than active emotions. Implications for ethical decision-making
research and organizational practices are discussed. 相似文献

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.

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.

This study examines the long memory behavior in gold returns during the post-Bretton Woods period using a new rescaled range technique. Unlike the conventional rescaled range analysis, the new rescaled range analysis is robust to short-term dependence and conditional heteroscedasticity found in the gold data. Statistical results suggest that the long memory behavior in gold returns is rather unstable. When only few observations corresponding to major political events in the Middle East, together with the Hunts event, in late 1979 are omitted, little evidence of long memory can be found. 相似文献

Because of the importance of Confucian doctrines in shaping ethical business practices under Chinese leadership, revealing the roles of other Chinese ethical doctrines in modern Chinese leadership is informative. A thorough understanding of the ethical foundations of Chinese leadership is necessary for fruitful interaction with Chinese leaders, according to cultural fit theory. The present study illustrates the philosophical foundations of business management, based on dialogues with five eminent corporate executive officers (CEOs). It reveals that the CEOs practice a style of Chinese leadership synthesizing Confucian, Daoist, Mohist, and Legalist doctrines. The Confucian doctrines advocate benevolence, harmony, learning, loyalty, righteousness, and humility. They are the most prevalent tenets that support paternalism and collectivism. The Daoist doctrines emphasize flexibility and reversion (e.g., the principle that the weak can defeat the strong). They bolster the leader’s forbearance. The Mohist doctrines underpin thrift and working with the masses whereas the Legalist doctrines inculcate self-control and innovativeness. Hence, contemporary Chinese leadership does not rely exclusively on Confucian ethics and this reflects evolution over 1000s of years. 相似文献
