While univariate nonparametric estimation methods have been developed for estimating returns in mean-downside risk portfolio optimization, the problem of handling possible cross-correlations in a vector of asset returns has not been addressed in portfolio selection. We present a novel multivariate nonparametric portfolio optimization procedure using kernel-based estimators of the conditional mean and the conditional median. The method accounts for the covariance structure information from the full set of returns. We also provide two computational algorithms to implement the estimators. Via the analysis of 24 French stock market returns, we evaluate the in-sample and out-of-sample performance of both portfolio selection algorithms against optimal portfolios selected by classical and univariate nonparametric methods for three highly different time periods and different levels of expected return. By allowing for cross-correlations among returns, our results suggest that the proposed multivariate nonparametric method is a useful extension of standard univariate nonparametric portfolio selection approaches. 相似文献

This paper applies Plato’s cave allegory to Enron’s success and downfall. Plato’s famous tale of cave dwellers illustrates
the different levels of truth and understanding. These levels include images, the sources of images, and the ultimate reality
behind both. The paper first describes these levels of perception as they apply to Plato’s cave dwellers and then provides
a brief history of the rise of Enron. Then we apply Plato’s levels of understanding to Enron, showing how the company created
its image and presented information to support that image, and how the public eventually emerged from the cave to realize
the truth about Enron’s actual accounting practices and financial state, which led to the corporation’s downfall. We find
Plato’s allegory both useful in analyzing the relationship between Enron and the public and instructive about the power and
moral responsibility of Enron’s executives. 相似文献

We employ cooperative bargaining theory and Nash’s ‘rational threats’ idea to cast light on the biodiversity bargaining problem. The problem of global environmental negotiations is argued to be of the nature of a bargaining problem, in which bargainers
must agree on the distribution of cooperative surplus in order to move to the bargaining frontier. We discuss the importance
of both efficiency (bargaining frontier) and fairness (recognition of characteristics of bargainers) in the choice of the
appropriate contract. We show that the incremental cost contract, used to resolve the biodiversity bargaining problem, is
of the form of an extreme point contract that fails to recognise the contributions of the South to the production of cooperative
surplus. A rational response to such a contract is the use of threats of biodiversity destruction. Contracts must evince both
efficiency and fairness in order to represent lasting solutions. 相似文献

The electronics industry is often regarded by scholars as an example of a sector driven by endless technological innovation and major competition between a few large companies, thus embodying the common view whereby the free market leads firms to innovate. On the other hand, some business historians have also emphasised that, since the beginning of the twentieth century, most of these companies were engaged in various international cartel agreements. The business and economic history literature on this industry reveals a clear-cut divide between the inter-war years and the post-war era. In this paper, however, we argue that technical and commercial cooperation between large electronics companies continued in various forms despite the spread of anti-trust policies after 1945. In this case study, we explore the global X-ray equipment industry from its beginnings around 1900 to the advent of the CT scanner in the early 1970s. The paper focuses on Siemens and Philips, the two largest manufacturers of radiological equipment. It demonstrates that both companies pursued their commercial and technical cooperation at least until the 1970s, although it was much less overt as during the interwar years. 相似文献

Heineman BW 《Harvard business review》2007,85(4):100-8, 142
How does a large multinational keep thousands of employees, operating in hundreds of countries, honest in a high-pressure business environment? As the chief legal officer at General Electric for nearly 20 years, Ben Heineman was part of the senior management group that sought to do just that--to make sure its executives and employees are moved to do the right thing as strongly as they are motivated to make their numbers. Heineman describes a set of systems that combine the communication of clear expectations with oversight, deterrence, and incentives. Nowhere are the expectations higher--and the sanctions more powerful--than for top executives. Heineman recounts example after example of senior leaders terminated for ethical lapses even when the business consequences of doing so were painful--and even when they had no direct knowledge of the violations occurring on their watch. To make expectations clear throughout the company, GE has systematically sought to set uniform standards that stay well ahead of current legal developments and stakeholders' changing attitudes about corporate accountability. Responsibility for implementing those standards, which are embedded in GE's operating practices, rests with the business leaders in the field. Oversight is both methodical and multifaceted. A host of auditing and assessment systems enables GE to compare the performance of its various business units against one another and against industry benchmarks. Perhaps the most powerful is the company's ombudsman system, which doesn't just allow but requires employees to lodge concerns. Failures to report into the system or up the line, or retaliation in any form, are firing offenses. The current intense focus on board-level governance has missed the point, Heineman argues. It is time to shift the debate from board oversight of the CEO to how top company leaders can most effectively infuse integrity at all levels of the corporation. 相似文献

This study examines the moderating effects of corporate social responsibility (CSR) on the association between market orientation
and firm performance in the context of an emerging economy. The results from a sample of firms that operate in Dubai indicate
that CSR has a synergistic effect on the impact of market orientation on business performance. The results of our research
on the moderating effects of CSR on market orientation subsets reveal that although CSR moderates the association between
customer orientation and business performance, it does not moderate the association between competitive orientation and inter-functional
coordination and performance. The results of this study are discussed, and implications for practitioners and researchers
are presented. 相似文献
