There is a growing need to increase our understanding of ethical decision making in U.S. based organizations. The authors examine the complexity of creating uniform ethical standards even when the meaning of ethical behavior is being debated. The nature of these controversies are considered, and three important dimensions for ethical decision making are discussed: leaders with integrity and a strong sense of social responsibility, organization cultures that foster dialogue and dissent, and organizations that are willing to reflect on and learn from their actions. Leaders with integrity demonstrate consistency between vision and action that promotes trust, regularly concern themselves with developing moral standards, and are proactive agents of change in an increasingly complex world. Organizational cultures that support dialogue suspend judgments and increase their capacity to think together towards new levels of understanding. Ethical concepts evolve in these organizational cultures, and actions are informed and responsible. Organizations that reflect on their actions engage in double loop learning so that the time taken to reflect on the past and present leads to a more judicious and ethical future. In essence, the authors point to organizational guidelines for ethical decision making that lead to an increase in members' capacity to think and act ethically. Jonathan Z.

Three general types of problems entail different strategies. Continuing to seek solutions to tame problems when we face messes, let alone wicked problems, is potentially catastrophic hence fundamentally irresponsible. In our turbulent times, it is therefore becoming a strategic necessity to learn how to solve the right problems.

But then, you may agree that it becomes morally objectionable for the planner to treat a wicked problem as though it were a tame one, or to tame a wicked problem prematurely, or to refuse to recognize the inherent wickedness of social problems. Rittel and Webber (1973).

This study investigates the impact of acquisitions on the operating performance of Australian firms. For a sample of 36 Australian acquisitions occurring between 1986 to 1991 inclusive, and using matched firms to control for industry and economy-wide factors, the results based on four accrual and four cash flow performance measures show that corporate acquisitions do not lead to significant improvements in post-acquisition operating performance. The consistency of the results with the agency, the hubris and the financial motivation hypotheses suggests that corporate acquisitions in Australia may be undertaken for other than synergistic reasons. The results assist in explaining inconsistent findings reported in the literature.  相似文献

High-Water Marks and Hedge Fund Management Contracts   总被引:1,自引:0,他引:1  
Incentive fees for money managers are frequently accompanied by high‐water mark provisions that condition the payment of the performance fee upon exceeding the previously achieved maximum share value. In this paper, we show that hedge fund performance fees are valuable to money managers, and conversely, represent a claim on a significant proportion of investor wealth. The high‐water mark provisions in these contracts limit the value of the performance fees. We provide a closed‐form solution to the cost of the high‐water mark contract under certain conditions. Our results provide a framework for valuation of a hedge fund management company.  相似文献

We apply the modified rescaled range test to the return series of 1,952 common stocks. The results indicate that long memory is not a widespread characteristic of these stocks. But logit models of the event of a test rejection reveal that rejections are linked to firms with large risk-adjusted average returns. The maximal moment of a return distribution is also found to influence the event of a rejection, but not in a way suggestive of moment-condition failure. Evidence suggestive of survivorship bias is also uncovered. We conclude that there is some evidence consistent with persistent long memory in the returns of a small proportion of stocks.  相似文献

In search markets, greater spatial concentration of sellers increases price competition. At the same time, though, a greater concentration of sellers can create a shopping externality by attracting more buyers to the site. Using housing sales data, we test for spatial competition and shopping externality effects on prices and marketing time. We find that they reflect both competitive and shopping externality effects from surrounding houses, although the relative strength varies with how fresh the house is in the market, the freshness of surrounding houses, and the phase of the market cycle. New listings have the strongest shopping externality effect on neighboring houses that have been on the market for some time. Vacant houses have their strongest competition effects in the declining market and externality effects in the rising market. Fresh houses on the market reap little benefit from shopping externalities in all phases of the market cycle.  相似文献

This paper investigates the influence of industry uncertainty on the decision by established firms to enter a new industry. Specifically, we examine the tension between the option to defer , which discourages entry in the presence of uncertainty, and the option to grow , which may encourage entry in the presence of uncertainty when there are early mover advantages. Empirical analysis on data from a broad array of industries revealed that the effect of uncertainty on entry is not monotonic. Our findings are the first to find support for the nonmonotonic effect of uncertainty that has only recently emerged in theoretical treatments of real options theory, and amplify the importance of considering both the option to defer and the option to grow when contemplating entry. Furthermore, we found evidence that the relationship between uncertainty and entry is moderated by: (a) irreversibility, which influences the value of the option to defer; (b) the total value of growth opportunities; and (c) early mover advantages, which magnify the value of growth options.

This study investigates the effectiveness of the Tokyo Stock Exchange (TSE)-traded Japanese 10-year JGB futures contract to hedge portfolios of Japanese bonds of differing maturity and credit quality. The bond portfolios examined are Government, AAA-, and AA-rated Eurobonds with maturities of 2, 3, 5, 7, 10, and 20 years. Consistent with the recent literature, the study employs univariate methods for calculating hedge ratios based on levels, first differences, and percentage change of each series. Out-of-sample forecasting is used to determine the effectiveness of the calculated hedge ratios for each of the bond portfolios and to determine which approach to calculating hedge ratios is the most effective. The results show that this particular futures contract does provide a good hedge, particularly for those bond terms closest to the 10-year term of the contract. There is some evidence, although not strong, that JGBs are better hedged than AAA and AA bonds. Investors should take some caution when using this futures contract to hedge bond portfolios of different maturities and credit ratings.  相似文献
