This article provides empirical evidence and contributes to theory building concerning business model fit and dynamics in the area of solutions business. Business models are seen in this context as going beyond considerations such as offerings and internal processes or even relationships, and as including network and market considerations. Indeed the paper highlights the fact that a business model is not firm-focused, nor dyad-focused, but rather network-, and even market-focused, demonstrating that a business model is not static, but dynamic. Manufacturer and customer continuously shift form and content of their respective business models to adapt both to the needs of the counterpart and to market context. A qualitative case study approach is adopted, with subsequent content analysis. The case study relates to the aerospace industry with focus on a complex engineering firm, one of the largest aircraft manufacturers in the world, its customer — a national airline — and their network partners of various kinds. The data were collected through multiple face-to-face interviews with managers in both companies, as a part and parcel of a network of actors that influences and is influenced by the supplier–buyer relationship. Relationships over time between these firms and network partners are described, highlighting the interplay of products and services related to the provision of solutions. Findings highlight the dynamic nature of business models over the relationship lifecycle between supplier and customer in a complex engineering environment, and the need for reciprocal adjustment of models.  相似文献

This study investigates the relevance of reported earnings in the context of an institutional environment, i.e., Switzerland, in which investors focus on dividends. In conjunction with a dividend focus, the financial reporting environment faced by Swiss firms provides their managers with more accounting discretion than managers of Anglo-Saxon firms typically have. From a contractual perspective, dividendbased earnings management is expected since Swiss corporate law explicitly states that dividends, which must be voted on by stockholders, are to be based upon a firm's reported earnings. From a value perspective, thin trading conditions and a long-term investment horizon are expected to increase the importance of dividend payments and to influence the informativeness of reported earnings. Results indicate that Swiss managers do engage in dividend-based earnings management, that earnings quality signals are used by managers to voluntarily constrain their accounting choices and that the value relevance of earnings is conditional upon dividend payments.  相似文献

Proponents argue that mergers should be encouraged as a legitimate strategy to avert (presumably undesirable) hospital closures. More recently, antitrust activity directed at not-for-profit hospitals has intensified. This study attempts to shed some light on the policy debate by testing whether merger targets are indeed candidates for closure, namely hospitals with persistent losses. Acquisitions of independent not-for-profit hospitals by other hospitals and by multihospital corporations are observed from a national sample for the period 1982–1987. The likelihood of being acquired in during any year within that period is estimated using a discrete-time hazard rate model. We find no evidence to support the notion that hospitals with weak financial indicators are more likely to be acquired. Rather, we find that hospitals with high operating-margins that are located in less regulated markets, and to a certain extent in high-growth markets, are more likely to be acquired. These findings cast doubt on certain predictions found in the theoretical literature, but are in agreement with empirical studies of other industries.  相似文献

A bstract An international carbon tax has been the subject of considerable recent discussion as an economic incentive instrument to combat the perceived threat of global warming lesuking, primarily, from the use of the carbon emitting fossils–coal, oil, and natural gas–in the production of energy. During 1991, the European Union proposed the adoption of such a tax to be imposed by each member nation. The economic merits as well as the problems associated with the proposed European carbon tax are discussed along with the political prospects for its adoption. It is concluded that even though early adoption of the tax is unlikely, the economic merits of this tax instrument for the alleviation of global warming accompanied by changing political parameters may lead to its adoption in the long run.  相似文献

There is no clear consensus as yet concerning the possible regional agglomeration impacts of Japanese Just-In-Time manufacturing techniques. This paper attempts to provide a theoretical structure to discussing such questions and then uses a logit model to analyse evidence from the Scottish Electronics Industry. The results provide support to the suggestion not only that the adoption of such techniques within the UK will encourage the shortening of input linkages, but also that this phenmenon is not restricted purely to the case of the automotive industry.  相似文献

关于中国货币政策的分析与建议   总被引:1,自引:0,他引:1  
中国人民银行在货币政策战略方面已经取得了巨大成绩,但随着经济的日趋复杂,货币政策的有效性将会降低。实证研究表明中国需要维持对货币的盯住(a reference to money)战略以及加强利率在货币政策执行中的作用。我们建议采取折衷性战略,包括盯住若干指标,并将短期利率作为执行目标。应该赋予央行利率政策的自主权,在不远的将来实现这一目标不存在技术上的障碍。  相似文献

Firm level data for the manufacturing sector in Africa, presented in this paper, shows very low levels of investment. The importance of profit effects on investment is investigated using a flexible accelerator, a specification based on the Euler equation and a simple generalisation of these specificiations. There are controls for firm fixed effects. It is shown that the profit effect is very similar for both the accelerator and Euler equation specifications. A comparison with other studies shows that, for small firms, the effect is much smaller in Africa than for other countries. Reasons for the relative insensitivity of investment to profits in African firms are suggested. For the most general specification tested there are no significant differences in the size of the profit effect across the four countries in the study.  相似文献
