In most surveys, one is confronted with missing or, more generally, coarse data. Traditional methods dealing with these data require strong, untestable and often doubtful assumptions, for example, coarsening at random. But due to the resulting, potentially severe bias, there is a growing interest in approaches that only include tenable knowledge about the coarsening process, leading to imprecise but reliable results. In this spirit, we study regression analysis with a coarse categorical‐dependent variable and precisely observed categorical covariates. Our (profile) likelihood‐based approach can incorporate weak knowledge about the coarsening process and thus offers a synthesis of traditional methods and cautious strategies refraining from any coarsening assumptions. This also allows a discussion of the uncertainty about the coarsening process, besides sampling uncertainty and model uncertainty. Our procedure is illustrated with data of the panel study ‘Labour market and social security' conducted by the Institute for Employment Research, whose questionnaire design produces coarse data. 相似文献

Extant literature on sustainable business models highlights that value creation stems from resources exchanged in relationships between a focal firm and its stakeholders. In this context, the literature has, so far, focused on direct relationships. However, despite the acknowledged relevance of sustainability issues in supply chains, this relational view of the focal company and its direct stakeholders has not been extended toward value creation for and with indirect stakeholders, such as stakeholders of suppliers. Addressing this gap, this conceptual article integrates a relational view of sustainable supply chain management into the management of sustainable business models. It extends the scope of sustainable business models from relationships between the focal firm and its direct stakeholders to indirect relationships with stakeholders of suppliers. A framework is developed that supports analysis and management of value-creating relationships between the focal firm, suppliers, and stakeholders of suppliers. By extending the conceptualization of sustainable business models to consider relationship chains beyond direct relationships, this article proposes that a focal firm has to actively manage interactions both with suppliers and with suppliers' stakeholders. 相似文献

In the second half of 2009, the entire media agenda in Germany was dominated by the swine flu, next to the German Federal Parliament elections. Criticism was voiced in the media against the pharmaceutical industry for lobbying the nationwide swine flu vaccination, which was widely considered nothing but a product of the industry’s lobbying power. In order to avoid the usual interviews with lobbyists, we attempted to apply a new methodological framework approach in analysing lobbying processes and key stakeholders in the public sphere—and outside. Crucial to the diversified approach, which involves quantitative content analysis of media coverage and press releases, are interviews with journalists, lobbyists’ network analysis and internet research on biographies. Although a conspiracy could not be conclusively proven, the results do indicate associations that validate the criticism of the industry’s lobbying activities. 相似文献

In a fixed exchange rate regime, an exchange rate change can be a swift way to change the real exchange rate in the short
run. Fiscal policy also affects relative prices, and fiscal policy response to various types of shocks can therefore be crucial
for the credibility of an exchange rate peg. We develop a model within which fiscal policy plays a crucial role for ensuring
the viability and thus credibility of an exchange rate peg. We use the insights of this model to take a closer look at Denmark,
which has successfully pursued a fixed exchange rate policy since 1982.

Drawing on a qualitative case study of 51 organizational self-initiated expatriates (OSIEs) in a professional services firm, this article investigates the role of networks during expatriation and, specifically, in the development of learning that is beneficial to both the individual expatriate and the global operations of the firm. First, we investigate the extent to which individual motivations to engage in OSIE impact on the development of networks. Second, we investigate individual's experiences of network development. Third, we investigate individual perceptions of the benefits of networks for both organizations and individual actors. The paper will report that professionals initiating their own expatriation develop continually expanding and composite networks such that mobility and networks evolve in a seemingly symbiotic relationship. In doing so, it contributes to our understanding of the role of agency in network development and extends our understanding of organizational self-initiated expatriation as a relatively under-researched phenomenon. 相似文献

Firms are increasingly integrating sustainability into their supply chain management (SCM) practices. The goal is to achieve sustainable flows of products, services, information and capital to provide maximum value to all corporate stakeholders. Prior research on SCM integration has insufficiently addressed sustainability. The objective of this research is to provide for a coherent and testable model of sustainable supply chain management integration (SSCMI). By drawing on four cases from the German manufacturing industry, we seek to identify the most important factors that enable or impede the integration of sustainability into SCM. 相似文献

The aim of this study is to analyze similarities and differences between companies with traditional sustainability reporting (TSR) and those that publish integrated reports. Based on institutional theory we identify potential determinants of integrated reporting (IR) and test their relevance empirically in a sample of 309 companies. Our analysis shows that IR companies are different from TSR companies with regard to several country‐level determinants. In particular, investor and employment protection laws, the intensity of market coordination and ownership concentration, the level of economic, environmental and social development, the degree of national corporate responsibility and the value system of the country of origin proved to be relevant. Based on these results, both implications for practice and future studies are derived. Copyright © 2011 John Wiley & Sons, Ltd and ERP Environment. 相似文献
