Program instability, low levels of capital investment and uneconomical production rates have been recognized as significant problems in defense acquisition programs. In this paper, we use a dynamic programming model under uncertainty to investigate the relations among these problems. We show that capital investment and production rates that appear to be too low may be the result of cost minimizing responses by contractors to program instability. Attempts to change the level of capital investment or production rate on defense programs without regard to the nature of program instability may hinder efficient resource allocation.The refereeing process of this paper was handled through J.F.

The phenomenon of mass fun running in Britain dates from the early 1980s and displays much of the ideology of the ‘Sport For All’ campaign. While running as an activity can be viewed as a natural pastime, the notion of mass jogging, as exemplified by the Great North Run and the London Marathon, is more difficult to comprehend and requires further analysis. This paper argues that the mass fun run is an example of the ‘Society of Spectacle’: a commercial creature which is heavily reliant on media coverage and sponsorship and which serves as an endorsement and symbol of postmodern society. The media stresses the ‘tradition’ of such events and uses them as images of human decency and national unity. Yet the relationship between audience, participant and spectacle remains fragile and dependent upon commercial considerations.  相似文献

In this conceptual article, the authors propose a framework for how progressive human rights outcomes may be obtained in the context of bidding, planning and implementing major sport events (MSEs) through the implementation of four pathways, including good governance, the democratic participation of stakeholders, the formalisation of human rights agendas and the deployment of sensitive urban development. The authors argue that there is a need for adherence to internationally recognised standards, such as the Universal Declaration of Human Rights and the United Nations Guiding Principles on Business and Human Rights if rhetorical statements from MSE awarding bodies and host organisers are to be accountable to a wider set of actors. If researchers and practitioners want to address some of the critical issues related to human rights and MSEs, it is imperative that key actors working in the rights sphere are involved in shaping the research agenda and monitoring its implementation. Academics need to take a proactive approach aimed at achieving both theoretically grounded and practically relevant solutions, with engagement occurring over an extended period of time. This approach, avowedly political and concerned with genuine action, is a key way in which MSE stakeholders can be held to account for their actions in regard to human rights.  相似文献

This study examines the underlying dynamics of strategic decisions that are subject to upward influence activity. The results suggest that the strategymaking process deviates considerably from typical rational comprehensive approaches in that strategies are affected by: initial sense-making activity, perceptions of risk and return, and power and negotiation skills. Differences due to functional area of the manager involved in the influence activity are discussed.  相似文献

Bundled coverage of different losses and distinct perils, along with differential deductibles and policy limits, are common features of insurance contracts. We show that, through these practices, insurers can implement multidimensional screening of insurance applicants who possess hidden knowledge of their risks, and thereby reduce the externality cost of adverse selection. Competitive forces drive insurers to exploit multidimensional screening, enhancing the efficiency of insurance contracting. Moreover, multidimensional screening allows competitive insurance markets to attain pure strategy Nash equilibria over a wider range of applicant pools, resolving completely the Rothschild–Stiglitz nonexistence puzzle in markets where the perils space is sufficiently divisible.  相似文献

In this paper, we examine whether nominal stock price can help to explain the ex-dividend day anomaly where stock prices drop by less than the dividend amount on the ex-dividend date. We find that stocks with lower nominal prices have ex-dividend day price drops that are more consistent with theoretical predictions based on an efficient market. After controlling for factors that have been previously documented to influence ex-dividend day stock price behavior, price-drop-to-dividend ratios are closer to one for lower priced stocks. To further explore this phenomenon, we examine the change in the price-drop-to-dividend ratio around stock splits. Firms that split their shares have a larger price-drop-to-dividend ratio after the split, and companies that reverse split their shares have a smaller price-drop-to-dividend ratio after the split. Our evidence indicates that ex-dividend day stock price behavior is influenced by the nominal price of a share and that this relation could also influence the decision to split a firm’s shares.  相似文献

In this discussion that took place at the SASB 2016 Symposium, the former Chair of the Securities and Exchange Commission explores recent developments in corporate sustainability reporting with three Directors—two past and one current—of the SEC's Division of Corporation Finance (or “CorpFin”). The consensus of the panelists was that investors want companies to provide more and better disclosure of their ESG exposures, particularly climate change, and their plans to manage those exposures. According to the current director of CorpFin, the most common demand expressed in the thousands of “comment letters” elicited by the SEC's recent concept release was for more and better sustainability information. And among the many issues cited by investors in those letters, including economic inequality, corruption, indigenous rights, and community relations, the subject of greatest interest by far was climate change. While none of the panelists claimed to see private‐sector demand for SEC action and a new set of mandatory requirements, all seemed to agree that many companies would welcome the establishment of voluntary guidelines and standards for providing ESG information—and that the guidelines recently developed by the Sustainability Accounting Standards Board are a promising model. For companies in each of 79 different industries, the SASB has identified a specific set of “material” concerns along with metrics or KPIs that can be used to evaluate corporate performance in responding to those concerns. Perhaps the most important advantage of this approach is that, by limiting such reporting to material exposures (and so adhering to a principle that has long informed SEC requirements), the SASB guidelines should significantly increase the relevance and value to investors—while possibly holding down the costs—of the sustainability reports that large companies in the U.S. and abroad have been producing for decades. But, as the former SEC Chair also notes in closing, the adoption of such guidelines by companies should be viewed as just a first step toward improving disclosure. To help companies develop the most useful and cost‐effective disclosure practices, investors themselves will have to become more active in communicating their own demands and preferences for information.  相似文献

In an integrated corporate tax system, resident shareholders receive a tax credit for corporate tax paid that can be used to offset personal tax on dividend income. Nonresident and tax-exempt (pension plan) investors cannot use the tax credit on corporate dividends and thus prefer to invest in flow-through entities. We estimate the value of the flow-through entity to nonresident and pension plan investors by examining the price change around the date of an unexpected announcement of a change in tax law related to Canadian publicly traded income trusts units creating an entity-level tax that makes them no longer tax-favored to these investors.  相似文献
