Using internal records of board meetings, this research explores issues relating to the motivation of directors' action during takeover negotiations. The records relate to a time period when regulation was low and directors had ample opportunity to engage in adverse selection and moral hazard. In such circumstances, it might be supposed that they would have sought to protect their own tenure rather than seek to maximize shareholder wealth by recommending acceptance of a bid. However, in the case study under examination the directors worked hard to maximize the bid price by auctioning the company despite having little equity exposure themselves. The directors also sought to protect the interests of the staff when negotiating with bidders. Intentionally this behaviour was not disclosed to the shareholders and, on occasion, threatened the success of the negotiations. The article concludes that the actions of the directors were motivated by strong reputational effects not widely recognized in the contemporary literature as being a force that powerfully drives corporate governance.  相似文献

Value-at-Risk Prediction: A Comparison of Alternative Strategies   总被引:4,自引:0,他引:4  
Given the growing need for managing financial risk, risk predictionplays an increasing role in banking and finance. In this studywe compare the out-of-sample performance of existing methodsand some new models for predicting value-at-risk (VaR) in aunivariate context. Using more than 30 years of the daily returndata on the NASDAQ Composite Index, we find that most approachesperform inadequately, although several models are acceptableunder current regulatory assessment rules for model adequacy.A hybrid method, combining a heavy-tailed generalized autoregressiveconditionally heteroskedastic (GARCH) filter with an extremevalue theory-based approach, performs best overall, closelyfollowed by a variant on a filtered historical simulation, anda new model based on heteroskedastic mixture distributions.Conditional autoregressive VaR (CAViaR) models perform inadequately,though an extension to a particular CAViaR model is shown tooutperform the others.  相似文献

More than 100 miles from Bangalore, India, there's a rural area called Kuppam where one in three citizens is illiterate, more than half of the households have no electricity, and there's a high rate of AIDS. It's exactly this challenging atmosphere that prompted Hewlett-Packard to choose Kuppam as one of its first "i-communities" initiatives. Through the program, HP creates public-private partnerships to accelerate economic development through the application of technology while simultaneously opening new markets and developing new products and services. HP brings to these initiatives the management disciplines of a successful technology business. For example, it unearths customer needs using an iterative cycle that involves prototyping products and services and then closely observing residents' experiences with them. It fields a diversely talented team that brings many skills to the initiative, including deep technical ability, management acumen, and market knowledge. It takes a systems approach, simultaneously examining all the elements that must come together to create a working solution to a given problem. It establishes a "leading platform" on which other players--comapnies, nonprofits, and government agencies--can build technologies and applications. Practices like these help ensure that HP's investment yields real, sustainable results for the community in question. But HP also sees returns to its own business. In Kuppam, the company is discovering the need for (and developing) new products like a solar-powered digital camera, with printer, that fits in a backpack. By engaging the community and its leaders and working with them to design valuable new tools and capabilities, HP is gaining the knowledge it needs to be a stronger competitor in other developing regions.  相似文献

We investigate the efficacy of government guarantee programs for mortgage loans made on tribal lands by comparing lending outcomes for White applicants and Native Americans (NAs) living on- and off reservation lands. Simultaneous equations models with the loan-to-income ratio endogenous indicate both on- and off-reservation NA applicants experience higher conditional denial rates compared with otherwise similar White applicants. NAs living on-reservation are equally as likely to be approved for mortgage loans as off-reservation NAs. On-reservation applicants self-select lower loan-to-income ratios, and are held to a higher standard for this credit variable, likely because lower housing values and other economic variables challenge on-reservation applicants. Our findings suggest lack of financial resources, lack of applicant education about and experience with the mortgage process, low creditworthiness, and lender reluctance to confront burdensome bureaucracy limit on-reservation guarantee program success.  相似文献

Technical change will cause problems in the OECD area in all three sectors of manufacturing industry : consumer, intermediate, and capital goods. The author describes the factors influencing this process : the changes in demand, resource costs, competition, and technology. He discusses the growth and employment prospects for various sectors. It is a mistake to assume that the service sector will be able to absorb either the number or the type of workers displaced: structural unemployment poses a serious threat. Those countries able to adapt well to technical change are identified.  相似文献

This paper empirically analyses the relationship between the shadow banking system and implementation of monetary policy in China using the VECM methodology. We show that an increase in the size of shadow banking sector increases the independence of bank lending from the policies of the People Bank of China. We also find that Shadow Banking works in an asymmetric fashion in that it amplifies increases in the money supply but weakens the effects of restrictive interest rate-based monetary policy decisions.  相似文献
