This paper studies goodness-of-fit tests for the bivariate Poisson distribution. Specifically, we propose and study several Cramér–von Mises type tests based on the empirical probability generating function. They are consistent against fixed alternatives for adequate choices of the weight function involved in their definition. They are also able to detect local alternatives converging to the null at a certain rate. The bootstrap can be used to consistently estimate the null distribution of the test statistics. A simulation study investigates the goodness of the bootstrap approximation and compares their powers for finite sample sizes. Extensions for testing goodness-of-fit for the multivariate Poisson distribution are also discussed. 相似文献

The paper compares free trade with autarky in an asymmetric multi‐country world under Cournot competition with constant returns to scale and linear demand. We derive respective conditions under which free trade will hurt a country's consumers, benefit its firms, induce it to export, increase its output and raise its welfare. We show that these conditions are linked in a clear order, with one implying the next. We further demonstrate that free trade can reduce world total output and total consumer surplus as well as world welfare. Along the way, we correct several oversights in the literature. 相似文献

Patents serve as an indicator of the innovation capability of countries, industries, or firms. Many Indian firms are in a transition to move from labor intensive segments to areas with higher value added which has been reflected in this research. The purpose of this study is to analyze patents issued during the period of 1997–2009 from the European Patent Office database and the United States Patent and Trademark Office database from the top one hundred Indian information technology firms. This study represents a novel empirical look at information technology industry innovations in India. A comprehensive set of statistical patent analyses are presented to provide practitioners with valuable knowledge to assist in business strategic planning. 相似文献

Futures researchers have long been interested in studies that investigate the diffusion of innovations among consumers. Often this is simply as a basis for extrapolating future trends in access to technologies. But also this literature has been particularly useful in providing frameworks for understanding the processes by which new commodities come into circulation and spread across populations of adopters. In this paper we seek to deepen the analysis. We argue that many studies have oversimplified the issues by treating populations of potential adopters as being homogeneous. This, we believe, is inadequate for understanding the diffusion of products in consumer markets. Drawing on debates from cultural studies and the sociology of consumption, as well as emerging theories from evolutionary economics, and analysing household survey data, we show that there are discernible social groups that adopt products at different rates. These differential rates of adoption are attributable to the existence of groups with different tastes, and not simply a question of different income groups. 相似文献

As the implementation of corporate social responsibility (CSR) strategy requires promoting employee participation and initiating meaningful changes in organisational culture, the involvement of the human resource management (HRM) function in policy formulation and implementation is highly desirable. The relationship between the HRM and CSR functions is, however, under-investigated than other areas. Hence, there is a lack of clarity concerning HRM roles and the conditions under which they may be strategic or operational in nature. By drawing on data from interviews with 29 CSR and HRM professionals of large organisations in New Zealand, this paper argues that the role and contribution of the HR function in CSR is contingent on organisational variables such as the CSR structure, the scope and application of CSR and the nature of the HR functions. It concludes that in such contexts HRM is more likely to offer operational support in executing CSR rather than strategic input. 相似文献

This paper deals with consumer coping strategies when consumers experience difficulties in implementing an innovation. The particular setting for exploring this issue is a group of consumers in Michigan who are committed to eating local. The paper explores how these consumers cope or balance their commitment to eating local with the constraints they face on buying and preparing local food Following a literature review of coping strategy and consumer coping strategies in relation to innovations, the paper presents the results of three focus groups conducted with members of a Student Organic Farm, a food cooperative and a Slow Food Convivium. The consumers we interviewed mostly adopt problem‐centred, confrontative strategies: they change their food‐consumption habits including shopping, purchasing, cooking, storing and obviously, eating. None of these changes are easy to implement, and most require re‐allocations of time as well as trade‐offs to overcome time and cost barriers. In return, some of these consumers feel empowered. This study allows us to offer a working hypothesis that the process is dynamic: the more committed consumers are, the more they adopt problem‐centred, confrontative strategies and forget more fatalist emotion‐centred or avoidance strategies. These findings contribute to literature on consumers' coping strategies and suggest future research avenues. 相似文献
