The relative performance of several portfolio selection strategies is assessed empirically. These strategies vary in sophistication from a ‘naive’ strategy of maintaining equal dollar investments in each stock available to a strategy that periodically uses updated parameter estimates to calculate new optimal proportions of portfolio value to be invested in the stocks available. Although it is to be expected a priori that relatively sophisticated strategies will perform at least as well as the more naive strategies, implementation costs will clearly differ across strategies and across investor-specific parameters such as total portfolio value. Thus estimation of the various strategies' performance gross of these costs is a necessary consideration in rational strategy selection by any given investor. 相似文献

In this panel that also took place at the recent SASB Symposium, senior representatives of four leading institutional investors—BlackRock, Ca lPERS, Ca lSTRS, and Wells Fargo—emphasize the relevance of ESG data for “mainstream” investors and the importance of integrating it with traditional fundamental analysis rather than viewing it as a separate set of reporting responsibilities. Moreover, the logical place for integrating ESG information is in the most forwardlooking section of financial reports, the “Management Discussion and Analysis,” or “MD&A,” which would be strengthened by including more and better information about the companies' ESG risks and initiatives. Some panelists noted that ESG information is likely to be valued by investors because of its ability to shed light on “idiosyncratic” risks that are not captured by the traditional risk factors that have long dominated asset pricing models. Others described ESG information as helpful in evaluating and comparing the “quality” of management in portfolio companies. But all agreed that efforts like the SASB's to standardize ESG data are essential to successful integration of that data into the decision‐making process of large mainstream investors. And as the panelists also made clear, there is an important generational component to the growing movement to integrate ESG into mainstream investing, with Millenials—and particularly Millenial women—showing especially strong support. 相似文献

Prior research on the effectiveness of ethics education has yielded mixed results. In this sample of 686 employed adults, we found the majority felt there was little or no emphasis on ethics in their undergraduate program, and they felt poorly prepared to deal with ethical dilemmas at work. Among business, sciences, and liberal arts majors, those who majored in the sciences reported the lowest level of preparation for dealing with ethics issues. Management and law classes were the ones most frequently recalled by respondents as emphasizing ethics. Respondents made suggestions for improving undergraduate ethics preparation. 相似文献

Journal paper No. J-18684 of the Iowa Agriculture and Home Economics Experiment Station, Ames, Iowa, Project No. 3566, and supported by Hatch Act and State of Iowa funds. Using a world agricultural model, we analyze the impact on dairy markets of the Berlin Accord on the European Union (EU) Common Agricultural Policy (CAP) Reforms. We also investigate the consequences of enlargement of the EU to include the Czech Republic, Hungary and Poland for the same markets. We produce a market outlook up to 2010 for these two scenarios. The Berlin Accord induces lower EU milk and dairy prices. A change in relative prices between cheese and butter-skim milk powder (SMP) occurs after 2005 and induces an expansion of cheese production, consumption and exports at the expense of the butter–SMP sector. Accession of the three central and eastern European countries (CEECs) leads to a permanent but moderate decrease in EU prices of milk and dairy products. For the three acceding CEECs, domestic prices increase dramatically. Their final consumption of milk decreases and dairy product consumption drops considerably. The derived demand of milk in dairy production increases, however, because of the higher prices for dairy products, benefiting dairy producers in these CEECs. Dairy exports of the three acceding countries to the EU–15 increase by one to three orders of magnitude, despite building large inventories. The impact of accession on world markets is small. À l'aide d'un modèle agricole à l'échelle mondiale, nous analysons l'impact des accords de Berlin sur la réforme de la Politique agricole commune (PAC) de l'Union Européenne, en ce qui touche les marchés laitiers. Nous examinons aussi les conséquences éventuelles de l'élargissement de l'Union Européenne à la République Tchèque, à la Hongrie et à la Pologne. Ces deux scénarios nous ont servi de base d‘élaboration de perspectives du marché jusqu'en 2010. Les accords de Berlin déclenchent une hausse duprix du lait et desproduits laitiers dans l'UE. Selon nos prédictions, on assiste après 2005 à un changement du prix relatif du fromage par rapport à celui de la poudre de lait écremé (PLE). II s‘ensuit une expansion de la production et de la consommation et des exportations defromage aux dépens du segment de la PLE. L'entrée des trois pays de l'Europe, du centre et de l'est (PECE) conduit à une baisse permanente, encore que modeste, des prix du lait et des produits laitiers dans l'UE. Chez les trois nouveaux arrivés, les prix intérieurs grimpent de façon spectaculaire, ce qui entraîne une chute de la consommation du lait particulièrement de celle des produits laitiers transformés. En revanche, la demande de lait industriel augmente à cause des prix plus élevés des produits dérivés, ce qui profite aux producteurs laitiers des trois pays. Les exportations laitières de ces pays augmentent de 1 à 3 ordres de grandeur, ce qui n'empèche pas la constitution de stocks importants. L'impact de l'accession sur leur marchés mondiaux devrait être de peu d'importance. 相似文献

The open source model provides a valuable framework for collective knowledge production and dissemination. Open knowledge networks and other cooperative strategies (classified as open source discovery initiatives) are enabling biopharmaceutical companies to access disembodied knowledge‐based resources critical to downstream drug development. The objective of these cooperative strategic alliances is to preserve the downstream technological opportunities for multiple firms. When upstream discovery research cannot yield commercial products and when the costs associated with excessive upstream competition are too high, companies jointly benefit from cooperative knowledge production and open knowledge dissemination. An analysis of 39 open source initiatives (consortia) provides us with information on: the likely participants in such initiatives, the focus of knowledge production activities, the characteristics of the knowledge generated, and the management of joint knowledge assets. Based on this analysis, we use game models to understand the decision to participate in such strategic alliances better. Our game models provide a simple but elegant framework for understanding the impact of changing knowledge structures on the payoffs associated with cooperation and defection in knowledge production, and therefore on behaviour. 相似文献

The Heterogeneity of Socially Responsible Investment 总被引:1,自引:0,他引:1
Joakim Sandberg Carmen Juravle Ted Martin Hedesstr?m Ian Hamilton 《Journal of Business Ethics》2009,87(4):519-533
Many writers have commented on the heterogeneity of the socially responsible investment (SRI) movement. However, few have
actually tried to understand and explain it, and even fewer have discussed whether the opposite – standardisation – is possible
and desirable. In this article, we take a broader perspective on the issue of the heterogeneity of SRI. We distinguish between
four levels on which heterogeneity can be found: the terminological, definitional, strategic and practical. Whilst there is
much talk about the definitional ambiguities of SRI, we suggest that there is actually some agreement on the definitional
level. There are at least three explanations which we suggest can account for the heterogeneity on the other levels: cultural
and ideological differences between different regions, differences in values, norms and ideology between various SRI stakeholders,
and the market setting of SRI. Discussing the implications of the three explanations for the SRI market, we suggest that there
is reason to be sceptical about the possibilities of standardisation if not standardisation is imposed top-down. Whether this
kind of standardisation is desirable or not, we argue, depends on what the motives for it would be. To the extent that standardisation
may facilitate the mainstreaming of SRI, it could be a good thing – but we entertain doubts about whether mainstreaming really
requires standardisation. 相似文献

Conventional wisdom might lead us to conclude that the various disciplines involved in product development and management are often at cross-purposes. For example, practitioners from R&D and engineering have been known to suggest that marketing fails to understand the technical trade-offs involved in product management decisions. Conversely, marketing professionals sometimes complain that their technology-oriented colleagues pursue product development initiatives without adequate market awareness. And practitioners from both sides of this debate have asserted that research on new product development tends to be of the ivory tower variety, with little or no relevance for industry. Are such complaints valid? Perhaps it is time for a reality check. By searching academic literature on product development, Roger J. Calantone, C. Anthony Di Benedetto, and Ted Haggblom have compiled a list of 40 fundamental principles of new product development. This list forms the basis for a survey of new product practitioners from marketing and technical disciplines. The study provides a means for assessing whether practitioners agree with the fundamental principles of new product development that are identified in current academic literature. By obtaining responses from both marketing and technical professionals, the survey also sheds light on whether those two groups hold fundamentally different beliefs regarding new product development. The survey results reveal strong overall agreement among practitioners regarding these fundamental principles of new product management. Managers believe that 80% of the principles are either usually or almost always true. In other words, the survey results support the idea that the academic community is pursuing research issues that are relevant to practitioners, and that they are reaching valid conclusions. There are only a few cases in which the responses from the technical and marketing practitioners differ. Those disagreements probably result from differences in the basic orientations of the two groups. For example, it is not surprising that marketing managers would be more likely to agree that “product users and the marketplace form the most important source for new product ideas,” while technical managers more strongly support the idea that “radically new technologies constitute an important source of new product ideas.” The respondents noted overall disagreement with only a few of the 40 principles. In many of these cases, the academic literature has reached mixed conclusions. In other words, these “principles” might actually be oversimplifications, and further research is probably needed before we can fully understand the issues involved. 相似文献
