While an increasing number of philosophers and community activists argue in favor of corporate philanthropy, the practice is not without its critics. A number of firms that have restated suspect earnings also appear on lists of top corporate givers or are ranked among most ethical firms, prompting the suspicion that companies are using philanthropy as a kind of moral window-dressing. This paper explores whether restating firms are (1) using philanthropy to divert public attention away from suspect financial results; or (2) making donations to buy good will or a better reputation after they have been required to restate suspect earnings. Our results paint a mixed picture of the morality of corporate philanthropy. Firms forced to restate suspect earnings do seem to be using philanthropy either to divert attention away from their lackluster earnings or to elicit good will from the large community after such restatements. However, the reverse is not true. Just because a firm is a top giver, it does not follow that it is more likely to be a restater of earnings. Nor did we find evidence that firms ranked as very ethical are more likely to be restaters than non-restaters. Firms engage in philanthropy for a variety of reasons. We should not uncritically praise them for their giving, but neither should we regard with a cynical eye all corporate reputations for goodness or all corporation donations.  相似文献

Ensemble species distribution models combine the strengths of several species environmental matching models, while minimizing the weakness of any one model. Ensemble models may be particularly useful in risk analysis of recently arrived, harmful invasive species because species may not yet have spread to all suitable habitats, leaving species‐environment relationships difficult to determine. We tested five individual models (logistic regression, boosted regression trees, random forest, multivariate adaptive regression splines (MARS), and maximum entropy model or Maxent) and ensemble modeling for selected nonnative plant species in Yellowstone and Grand Teton National Parks, Wyoming; Sequoia and Kings Canyon National Parks, California, and areas of interior Alaska. The models are based on field data provided by the park staffs, combined with topographic, climatic, and vegetation predictors derived from satellite data. For the four invasive plant species tested, ensemble models were the only models that ranked in the top three models for both field validation and test data. Ensemble models may be more robust than individual species‐environment matching models for risk analysis.  相似文献

We study a continuous‐time principal–agent model in which a risk‐neutral agent with limited liability must exert unobservable effort to reduce the likelihood of large but relatively infrequent losses. Firm size can be decreased at no cost or increased subject to adjustment costs. In the optimal contract, investment takes place only if a long enough period of time elapses with no losses occurring. Then, if good performance continues, the agent is paid. As soon as a loss occurs, payments to the agent are suspended, and so is investment if further losses occur. Accumulated bad performance leads to downsizing. We derive explicit formulae for the dynamics of firm size and its asymptotic growth rate, and we provide conditions under which firm size eventually goes to zero or grows without bounds.  相似文献

This paper presents an approach to assessing the potential of countries to lead the global adoption of an innovation and to set a global product or process standard. It can be observed that the specific design of an innovation diffuses worldwide after it has been adopted in a single country. We suggest that there are nation-specific characteristics that increase the likelihood that a locally preferred innovation design will become successful in other countries, too. Once users in a market that has lead market characteristics have adopted a specific innovation design, the possibility increases that users in other countries subsequently adopt it as well. We present a lead market concept for the development of global innovation designs. By focusing on the design of the innovation that responds to the preferences within the lead market, a company can leverage the success experienced in the lead market for a global market launch. In order to follow a lead market strategy of new product development, it is necessary to assess the lead market potential of countries before an innovation is developed and tested in the market. We use an indicator-based methodology that approximates the lead market attributes of countries. The assessment methodology is applied to two innovation projects at the truck division of DaimlerChrysler.  相似文献

Uses and gratifications (U&G) is a media use paradigm from mass communications research that guides the assessment of consumer motivations for media usage and access. It has been used previously in research and decision making related to the promotion of emerging radio and television media. Recent adaptations of U&G research to the Internet are incomplete and have not identified important new Internet‐specific gratifications. This paper empirically derives dimensions of consumer Internet use and usage gratifications among customers of a prominent Internet Service Provider (ISP). Results describe three key dimensions related to consumer use of the Internet, including process and content gratifications as previously found in studies of television, as well as an entirely new social gratification that is unique to Internet use. All three dimensions of gratification are relevant to managing the Internet as a commercial medium, and measures developed from the gratification profiles identified here can serve as trait‐valid scales in future Internet and e‐commerce research.  相似文献

This article uses the Deming management model developed by Anderson et al. (1994b) as an initial template to analyze total quality in services. While the literatures addressing quality management have developed separately for products and services, the founders of total quality portrayed this management philosophy as universally oriented. Our study first replicates two earlier studies that tested the Deming management model in manufacturing industries. Using hospitals as our unit of analysis, we realized findings similar to the earlier manufacturing studies. Next, we used contributions from the MBNQA literature to test an enhanced model. Our subsequent findings support the MBNQA concept that “leadership drives the system that creates results” and provides evidence of the ubiquitous importance of leadership for ensuring the success of a quality improvement program. Finally, an anomaly of this study and those published earlier is the inability to find support for the relationship between continuous improvement and customer satisfaction. Integrating the substantial work in the service quality literature focused on customer satisfaction measurement is recommended to future researchers to help resolve this issue and further enhance the model.  相似文献

In the emerging knowledge economy many companies are forced to access globally dispersed technological and market knowledge to maintain their competitive advantage. A conceptual model is presented to analyze the relationship between the globalization of the innovation function and firm performance. Longitudinal data from 10 multinational companies are used to support the proposed model. The analysis concludes that the relationship between global innovation reach and firm performance is concave and time lagged. The results suggest the strategic importance of globalization decisions. The managerial implications are structured in five distinctive strategic challenges to successfully manage global innovation.  相似文献

We study a newsvendor who can acquire the services of a forecaster, or, more generally, an information gatherer (IG) to improve his information about demand. When the IG's effort increases, does the average ex ante order quantity rise or fall? Do average ex post sales rise or fall? Improvements in information technology and in the services offered by forecasters provide motivation for the study of these questions. Much depends on our model of the IG and his efforts. We study an IG who sends a signal to a classic single‐period newsvendor. The signal defines the newsvendor's posterior probability distribution on the possible demands and the newsvendor uses that posterior to calculate the optimal order. Each of the possible posteriors is a scale/location transform of the same base distribution. When the IG works harder, the average scale parameter drops. Higher IG effort is always useful to the newsvendor. We show that there is a critical value of order cost. For costs on one side of this value more IG effort leads to a higher average ex ante order and for costs on the other side to a lower average order. But for all costs, more IG effort leads to higher average ex post sales. We obtain analogous results for a “regret‐averse” newsvendor who suffers a penalty that is a nonlinear function of the discrepancy between quantity ordered and true demand.  相似文献

In this paper we attempt to identify the research frontier in corporate governance using three different approaches: (1) what challenges does the financial crisis 2007–2009 pose for corporate governance research? We show that the financial crisis is a huge natural experiment which has exposed gaps in our knowledge of corporate governance and is likely to lead of a rethink of central concepts like shareholder value, debt governance, and management incentives (2) what do we know and what do we need to how about the impact of national institutions on corporate governance? (3) What research questions are raised by a focus on current corporate governance practices?  相似文献

Of Polls, Mountains: U.S. Journalists and Their Use of Election Surveys   总被引:1,自引:0,他引:1  
Polls are a prominent feature of U.S. election news coverage.Although polls are used to explain voter opinion, they are employedmostly to fuel horse-race coverage and to craft images consistentwith the candidates’ positions in the race. Moreover,U.S. journalists sometimes misinterpret polls by slighting thepossibility that changes in candidate preference are the resultof survey error rather than real change. On balance, U.S. journalists’dependence on polls adversely affects the quality of Americanelection coverage.  相似文献
