Predicting Corporate Failure and Global Financial Crisis： Theory and Implications

The purpose of this paper is to discuss corporate failure issues in the context of the global financial crisis. After considering some key issues, the paper shows how relevant these issues are relevant in the present financial fiasco. It is clear that corporate failure brings untold hardships to all stakeholders. Again the problem of predicting corporate failure in the midst of the financial contagion could be overcome with sound risk management structure in place. The discussion mainly focuses on corporate failure within the context of the global financial distress. To the best of our knowledge this study is the first of its kind, which provides conceptual insights on predicting corporate failure and the global financial distress.

Controlling the Risk of Construction Delay in the Middle East： State-of-the-Art Review

The financial crisis in late 2008 arrested economic development in the construction sector in the Middle East, with the result that investors＇ confidence in the sector is severely depressed. Delays constitute one of the highest impediments to project success. In this respect, the traditional management is no longer sufficient for construction project success. The objective of this study is to conduct a literature review to identify additional effective measures for controlling the potential delays risks in construction projects in order to maximize the opportunities for success in those projects. Thirty-six scholarly articles published between 2000 and 2011 are reviewed to identify related MDRC （measures for delays risks control）. This survey reveals that 60% of the studies are related to decision-making, performance, risk management variations and poor management knowledge of stakeholders and that 20% of these studies are undertaken in the Middle East. A further 25% of the studies are related to the lack of financial risk by stakeholders, and of these 14% are in the Middle East. A knowledge gap is identified in terms of project performance, stakeholder management and risk management, which are seen as significant measures of success in controlling project delay.

Corporate Sustainability and Ethical Codes Effectiveness

In the last years, the issues regarding both sustainable development and business global responsibility have qualified the corporate governance effectiveness. Many international institutions have intervened and the companies, at least formally, have increased their attention to the interaction between stakeholder relationship management and economic, social, and environmental responsibility. The numerous and frequent scandals underline the discrepancy between the firms＇ formal statements and the substantial behaviors. Most of the companies, in the industrialized country, publish well-structured code of ethics and conduct, explicating the strategic values assigned to the global responsibility. The research considers the capability of the code of conduct to influence effectively the behaviors, in relation with the needs of transparency, sharing, coherent individual behavior, and control. In relation to the importance conferred to the sustainable development by the European Union （EU）, the analysis examines listed companies with the greatest market capitalization operating in the Great Britain, Germany, and Italy, in order to verify the firms＇ behavioral uniformity and the effectiveness of sustainability policies. The analysis shows that the codes of ethics seem to remain only formal declarations. Conscious and rational governance not only transfers values and principles of sustainability to the firm＇s behaviors and its result system, but also goes beyond a mere diffusion and formalization of codes of ethics and conducts. To achieve that, it is necessary to develop productive behaviors focused on the risk control and on managing behaviors of all the organization＇s members, in particular in reference to the stakeholder relationship management. The codes of ethics, in fact, seem to assume a poor relevance for the corporate sustainability promotion if a correct formal structure does not occur integrated with strategies and processes which assure a constant workability. It requests especially： the ethic culture diffusion and sharing of related values and principles; definition and integration of critical success dimensions in relation to economic, environmental, and ecological responsibility; and identification of relevant ethical parameters and control of their observance.

Covariance Estimation Using High-Frequency Data： An Analysis of Nord Pool Electricity Forward Data

The modeling of volatility and correlation is important in order to calculate hedge ratios, value at risk estimates, CAPM （Capital Asset Pricing Model betas）, derivate pricing and risk management in general. Recent access to intra-daily high-frequency data for two of the most liquid contracts at the Nord Pool exchange has made it possible to apply new and promising methods for analyzing volatility and correlation. The concepts of realized volatility and realized correlation are applied, and this study statistically describes the distribution （both distributional properties and temporal dependencies） of electricity forward data from 2005 to 2009. The main findings show that the logarithmic realized volatility is approximately normally distributed, while realized correlation seems not to be. Further, realized volatility and realized correlation have a long-memory feature. There also seems to be a high correlation between realized correlation and volatilities and positive relations between trading volume and realized volatility and between trading volume and realized correlation. These results are to a large extent consistent with earlier studies of stylized facts of other financial and commodity markets.
