This article describes the results of a research project which examined 171 alliances set up by competing firms in an international context. It presents an empirically-based taxonomy of such alliances constructed on the basis of a set of variables chosen for their demonstrated or assumed influence on the evolution and outcomes of strategic partnerships. Three contrasted types of alliances are identified: quasi-concentration alliances, market penetration alliances and shared supply alliances. They differ according to two fundamental dimensions: their symmetrical or dissymmetrical nature and the way in which they alter competition. Legal structure, often emphasized in previous research on the subject, does not emerge as a strongly discriminating factor. Hypotheses on the likely evolution and outcomes of each type of alliance are derived from the taxonomy.We are grateful to Barbara Gray, Stuart Hart, Aneel Karnani, Will Mitchell, Michel Tenenhaus, and to two anonymous reviewers for their very valuable and helpful comments on earlier drafts of this article. Our research project was funded by Fondation HEC, whose support we gratefully acknowledge. 相似文献

In standard portfolio theories such as Mean–Variance optimization, expected utility theory, rank dependent utility heory, Yaari’s dual theory and cumulative prospect theory, the worst outcomes for optimal strategies occur when the market declines (e.g. during crises), which is at odds with the needs of many investors. Hence, we depart from the traditional settings and study optimal strategies for investors who impose additional constraints on their final wealth in the states corresponding to a stressed financial market. We provide a framework that maintains the stylized features of the SP/A theory while dealing with the goal of security in a more flexible way. Preferences become state-dependent, and we assess the impact of these preferences on trading decisions. We construct optimal strategies explicitly and show how they outperform traditional diversified strategies under worst-case scenarios. 相似文献

This study proposes a new approach to the estimation of daily realised volatility in financial markets from intraday data. Initially, an examination of intraday returns on S&P 500 Index Futures reveals that returns can be characterised by heteroscedasticity and time-varying autocorrelation. After reviewing a number of daily realised volatility estimators cited in the literature, it is concluded that these estimators are based upon a number of restrictive assumptions in regard to the data generating process for intraday returns. We use a weak set of assumptions about the data generating process for intraday returns, including transaction returns, given in den Haan and Levin [den Haan, W.J., Levin, A., 1996. Inferences from parametric and non-parametric covariance matrix estimation procedures, Working paper, NBER, 195.], which allows for heteroscedasticity and time-varying autocorrelation in intraday returns. These assumptions allow the VARHAC estimator to be employed in the estimation of daily realised volatility. An empirical analysis of the VARHAC daily volatility estimator employing intraday transaction returns concludes that this estimator performs well in comparison to other estimators cited in the literature. 相似文献

University of Texas Roundtable on Financing and Managing Energy Investments in a Low‐Price Environment 下载免费PDF全文
Marshall Adkins Greg Beard Bernard “Buddy” Clark Gene Shepherd George Vaughan Sheridan Titman 《实用企业财务杂志》2016,28(1):30-45
During the past 18 months, the U.S. oil industry has seen oil prices plunge from well over $100 a barrel to under $30. In a session that was part of a recent Private Equity Conference at the University of Texas in Austin, the CEO of a small independent producer and a representative of a large global oil and gas company discussed the challenges of financing and operating energy companies in today's low‐price environment with the director of energy research at a brokerage firm, the senior partner responsible for the natural resource investments of a well‐known private equity firm, and the head of the oil and gas restructuring practice of a national law firm. The panelists appeared to reach a consensus on at least the following three arguments:

In this paper the concept of a municipal welfare function is defined. It reflects the evaluation by local authorities of several levels of local expenditures. On the basis of an extensive survey among all Dutch municipal authorities these functions are estimated for about 550 Dutch municipalities with respect to total expenditures and differentiated with respect to several portfolios, like public works, education, etc. The variation of the estimated municipal welfare parameters is explained by objectively measurable municipal characteristics like the number of the inhabitants, age distribution of inhabitants and houses, number of unemployed, regional situation. 相似文献

Drawing on evidence from twenty-five case studies from different sectors and parts of the country, the authors challenge Ramsay's influential ‘cycles of control’ theory of participation as a managerial response to industrial relations pressures from below. Through a series of ‘ideal type’ scenarios, they indicate the range of management motives behind the new ‘wave’ of employee involvement schemes. 相似文献

Our Collaborative Future: Activities and Roles of Stakeholders in Sustainability‐Oriented Innovation
Jennifer Goodman Angelina Korsunova Minna Halme 《Business Strategy and the Environment》2017,26(6):731-753
While stakeholders have long been at the forefront of sustainable development debates, the emphases have tended to be on different stakeholder pressures, or managing stakeholder expectations about controversial issues. In this paper we bring a fresh direction to these debates and ask in what ways different stakeholders can contribute to sustainable innovation in firms. Based on 80 semi‐structured interviews, we conduct a fine‐grained qualitative analysis of stakeholder activities in sustainability‐oriented innovation (SOI) processes in 13 different companies across Europe. Our analysis identifies eight roles that stakeholders play in SOI processes: stimulator, initiator, broker/mediator, concept refiner, legitimator, educator, context enabler and impact extender. More traditional roles such as legitimator and educator are less common in our cases. However, emerging roles such as stimulator, concept refiner, context enabler and impact extender are clearly identifiable and could be particularly valuable for SOI. We enhance a collaborative perspective of stakeholder theory, finding that stakeholders can play highly collaborative and proactive roles, and argue that secondary stakeholders may actually be more relevant for SOI than primary stakeholders.

This study examined the effect of definitions for organic and natural on willingness to pay a premium for organic over natural chicken. Data were collected using surveys and experimental auctions that were conducted before and after information was presented. Before information, approximately two‐thirds of participants inaccurately equated the requirements of natural with those for organic. After information, nearly 50% increased their premium, while 30% decreased their premium. Logistic regression results showed that consumers who had overestimated the requirements for natural were most likely to have an increased premium after information, with significantly higher bids for organic. For those who decreased their premium after information, awareness of consuming genetically modified (GM) foods was a key variable. The non‐genetically modified (non‐GM) requirement of organic appears to be of low value to some consumers. Overall, consumer confusion regarding organic and natural standards may be having substantial impacts on the two markets. 相似文献
