A small group of academics and practitioners discusses four major controversies in the theory and practice of corporate finance:
  • • What is the social purpose of the public corporation? Should corporate managements aim to maximize the profitability and value of their companies, or should they instead try to balance the interests of their shareholders against those of “stakeholder” groups, such as employees, customers, and local communities?
  • • Should corporate executives consider ending the common practice of earnings guidance? Are there other ways of shifting the focus of the public dialogue between management and investors away from near-term earnings and toward longer-run corporate strategies, policies, and goals? And can companies influence the kinds of investors who buy their shares?
  • • Are U.S. CEOs overpaid? What role have equity ownership and financial incentives played in the past performance of U.S. companies? And are there ways of improving the design of U.S. executive pay?
  • • Can the principles of corporate governance and financial management at the core of the private equity model—notably, equity incentives, high leverage, and active participation by large investors—be used to increase the values of U.S. public companies?

The success of an innovating firm often depends on the efforts of other innovators in its environment. How do the challenges faced by external innovators affect the focal firm's outcomes? To address this question we first characterize the external environment according to the structure of interdependence. We follow the flow of inputs and outputs in the ecosystem to distinguish between upstream components that are bundled by the focal firm, and downstream complements that are bundled by the firm's customers. We hypothesize that the effects of external innovation challenges depend not only on their magnitude, but also on their location in the ecosystem relative to the focal firm. We identify a key asymmetry that results from the location of challenges relative to a focal firm—greater upstream innovation challenges in components enhance the benefits that accrue to technology leaders, while greater downstream innovation challenges in complements erode these benefits. We further propose that the effectiveness of vertical integration as a strategy to manage ecosystem interdependence increases over the course of the technology life cycle. We explore these arguments in the context of the global semiconductor lithography equipment industry from its emergence in 1962 to 2005 across nine distinct technology generations. We find strong empirical support for our framework. Copyright © 2009 John Wiley & Sons, Ltd.  相似文献

This paper has a number of purposes. First, it revisits the older theory of reserve adequacy and optimality to see whether this can still be used and perhaps strengthened in ways that would inform the current debate. Second, it explores the connection between reserve adequacy and currency crisis in the light of recent experience and empirical research. Third, it critically investigates alternative rule‐of‐thumb measures of reserve adequacy. Fourth, and drawing on the foregoing analysis, it examines the extent to which crisis countries should seek to replenish and build up their international reserves in the post‐crisis period. Additional owned reserves represent a guaranteed and unconditional source of liquidity; is this what is needed?  相似文献

Objectives: Complexities in the neuropathic-pain care pathway make the condition difficult to manage and difficult to capture in cost-effectiveness models. The aim of this study is to understand, through a systematic review of previous cost-effectiveness studies, some of the key strengths and limitations in data and modeling practices in neuropathic pain. Thus, the aim is to guide future research and practice to improve resource allocation decisions and encourage continued investment to find novel and effective treatments for patients with neuropathic pain.

Methods: The search strategy was designed to identify peer-reviewed cost-effectiveness evaluations of non-surgical, pharmaceutical therapies for neuropathic pain published since January 2000, accessing five key databases. All identified publications were reviewed and screened according to pre-defined eligibility criteria. Data extraction was designed to reflect key data challenges and approaches to modeling in neuropathic pain and based on published guidelines.

Results: The search strategy identified 20 cost-effectiveness analyses meeting the inclusion criteria, of which 14 had original model structures. Cost-effectiveness modeling in neuropathic pain is established and increasing across multiple jurisdictions; however, amongst these studies, there is substantial variation in modeling approach, and there are common limitations. Capturing the effect of treatments upon health outcomes, particularly health-related quality-of-life, is challenging, and the health effects of multiple lines of ineffective treatment, common for patients with neuropathic pain, have not been consistently or robustly modeled.

Conclusions: To improve future economic modeling in neuropathic pain, further research is suggested into the effect of multiple lines of treatment and treatment failure upon patient outcomes and subsequent treatment effectiveness; the impact of treatment-emergent adverse events upon patient outcomes; and consistent and appropriate pain measures to inform models. The authors further encourage transparent reporting of inputs used to inform cost-effectiveness models, with robust, comprehensive and clear uncertainty analysis and, where feasible, open-source modeling is encouraged.  相似文献

A large body of literature points to sharply growing income inequality over the past half century. The Piketty and Saez dataset that measures income distribution provides empirical support for this claim. Our article evaluates three prominent criticisms of this dataset as well as the responses of Piketty and Saez to these criticisms. One key argument against using their dataset is that Piketty and Saez do not control for income shifting by top income earners in response to the Tax Reform Act of 1986 (TRA86) and thus overstate income inequality. In evaluating this criticism we find that a segment of their dataset likely understates income inequality; this is just the opposite of what critics assert. This implies that the Piketty–Saez dataset is a valuable resource for income inequality research and that scholars can use it to build more refined, accurate and insightful measures of income inequality.  相似文献

This paper uses a large panel of data with up to 19 time-series observations for almost 150 countries to estimate models of arms imports. Qualitative evidence suggests a non-linear relationship. As income and military expenditure grow, the propensity to import first rises and then falls as a domestic arms industry develops. We face the difficulty that there is virtually no data on domestic arms procurement or production capability. We respond to this difficulty by adopting a random coefficient approach in order to identify any systematic influences on import propensity, through the impact of military expenditure, size of the armed forces or income on unobserved domestic production capability. While a clear non-linear pattern is apparent in the cross-section relationship, once one allows for parameter heterogeneity such a pattern is not apparent in the time-series.  相似文献

This paper investigates national and organizational cultural influences among managers in three types of companies: Japanese companies in Japan, South Asian domestic companies and Japanese subsidiaries/joint ventures in South Asia. The findings suggest that a Japanese parent company's culture tends to have a much stronger influence with Japanese companies operating in Japan. Japanese parent company culture tends to have less influence than the South Asian national culture in shaping the HRM styles and practices in Japanese subsidiaries/joint ventures operating in South Asia. While some South Asian firms are in the initial stages of learning about participative HRM from foreign companies, most still tend to maintain their national culture and traditional ways in the operating systems of their organizations.  相似文献
