When modelling rating transitions as continuous-time Markov processes, in practice, time-homogeneity is a common assumption,
yet restrictive, in order to reduce the complexity of the model. This paper investigates whether rating transition probabilities
change after the origination of debt. Accordingly, we develop a likelihood-ratio test for the hypothesis of time-homogeneity.
The alternative is a step function of transition intensities. The test rejects time-homogeneity for rating transitions observed
over 7 years in a real corporate portfolio. Especially 1-year transition probabilities increase over the first year after
origination. This time effect suggests that banks should manage their credit portfolios with respect to the age of debt.

Effects of scale economies and production seasonality on optimal hub locations: the case of regional fresh produce aggregation 下载免费PDF全文
Interest in supporting local and regional food systems is rising and food hubs have attracted considerable attention among Federal, State, and local policymakers. This study explores the problem of endogenous hub location in fresh produce value chains in the Northeastern United States. To overcome limitations in the literature, we incorporate the effects of economies of scale and production seasonality into our models. Three experimental models are designed to examine the effects of alternatively applying yearly, quarterly, and monthly data on model solutions. We explicitly assess how interactions of scale economies and seasonality influence the structure and spatial attributes of an optimal regional produce aggregation hub system. The three models generate marketed different solutions and in many respects they lead to different conclusions about developing local/regional supply chains. The monthly model allows for production seasonality and actual hub operation cycle frequency and thus leads to more efficient hub solution with rich policy implications. 相似文献

Even though management scholars have offered several views on the process of corporate sustainability, these efforts have focused mainly on the technical aspects of sustainability while omitting the fundamental role played by individual moral competences. Therefore, previous work offers an incomplete and somewhat reductionist view of corporate sustainability. In this article, we develop a holistic framework of corporate sustainability in which both the moral and technical aspects of sustainability are considered. We do so by integrating the ethical, normative perspective of the Catholic social teaching (CST) with the competitive view of the natural resource-based view. This framework highlights the importance of CST principles and ideas in developing executive moral competences such as moral sensitivity and awareness, and moral cognition and motivation. Moral competences, in turn, influence the organizational selection of environmental strategies, giving leaders the intrinsic motivation to promote both a longer-term stance on corporate sustainability efforts and a relentless search for greener business models. Such strategies move the firm closer towards achieving environmental sustainability. Hence, by bridging the individual, normative-ethical with the organizational, implementational levels of corporate sustainability, our framework provides a more realistic, coherent, and complete perspective on the complex process of achieving corporate sustainability. 相似文献

We investigate the moderating role of national openness to foreign markets on consumer responses (attitude to ad, brand and purchase intention) to different degrees of advertising adaptation in Belgium, Iran and India. We operationalize three levels of advertising adaptation (standardization, glocalization and adaptation) by manipulating the model (international versus local celebrity) and advertising copy (international versus local advertising copy). The results show that societies with a low openness to foreign markets respond more positively to fully adapted ads than to glocalized and standardized ads. The differences in responses decrease with national openness. 相似文献

Self-efficacy influences students’ activities, effort and persistence, and it can help predict their motivation and academic performance. This study attempts to investigate the relationship between self-efficacy, preferred learning methods, and academic performance under different learning methods in a unique hospitality course setting. The results indicate that hospitality management students prefer a “learn by doing” approach instead of computer-based learning and lecturing. This study concludes that self-efficacy affects the academic performance in both lecturing and practical learning in hospitality education. However, students’ preference in terms of learning methods does not influence their academic performance. Emphasizing “learn by doing” in the hospitality higher education curriculum is recommended in addition to recruiting faculty members with extensive industry experience. Conversely, it is recommended that faculty find the means to increase students’ self-efficacy when adopting different teaching approaches. 相似文献

We examined how factors from Indigenous entrepreneurship research (social capital, cultural capital, self-efficacy) help explain the high level of Māori entrepreneurial performance in the mainstream screen industry. Results, based on ten case studies and a one-year series of structured interviews, extend prior research by showing that these Indigenous entrepreneurs benefit jointly from two forms of capital: cultural and social. We found high levels of both forms to increase the desire for emancipation of cultural and community identity – not just individual identity – through entrepreneurship. Self-efficacy and storytelling helped ameliorate discontinuities across Indigenous and mainstream contexts. Our research sheds new light on how Indigenous ventures can pursue mainstream entrepreneurship while maintaining cultural identity. It also makes several distinct contributions to the Indigenous entrepreneurship literature. First, it provides an integrative theoretic review. Second, it illustrates a culturally appropriate methodology for researching Māori entrepreneurs with implications for other Indigenous communities. Third, it proposes cultural capital and social capital as a two-part framework for explaining Indigenous entrepreneurial action. Fourth, it shows how entrepreneurship can be empowering for Indigenous communities. Finally, our paper demonstrates that entrepreneurship is a promising mechanism for preserving and promoting the cultures of Māori and other Indigenous peoples. 相似文献

The main purpose of this study was to identify the influence of the consumer’s country of residence on hotel service attributes’ contribution to consumer satisfaction. The hospitality services of Disneyland Paris in Paris, France, were analyzed in the context of the study. Data came from their seven hotels and comprised 47,885 valid questionnaires. The Tetraclasse model was applied to identify hotel attributes’ contribution to satisfaction and compare them for consumer segments from eight European countries and between hotels. Results showed that the four service attributes’ contributions are influenced by country of residence and vary between hotels. 相似文献

This study examined cancellation policies and their role in shaping travelers’ deal-seeking behavior, exploring the impact of cancellation fees and deadlines on three, mutually exclusive, customers’ hotel booking behavior categories: “Book”, “Book and Search”, and “Search”. 291 subjects, who participated in a week long online “booking game”, attempted to book a room in a virtual hotel and get the best deal. The results were tested using small sample t-test for comparing proportions between two independent populations, non-parametric multiple pairwise comparisons, and multinomial logit regression models. The findings indicate that the cancellation deadline affected participants’ behavior while the size of the cancellation fee had no statistically significant impact. In addition, there was no significant difference between lenient cancellation deadline and no cancellation policy. 相似文献

Beef cattle producers were surveyed in Texas and Nebraska to investigate perceptions of sources of risk, the effectiveness of risk management strategies, and interest in further risk management education, particularly production risk, using probit analysis. Important decision variables identified are age, prior use of risk management tools, previous attendances of risk management education, and risk aversion. Severe drought and cattle price variability are identified as primary risk factors with potential to affect farm income. Extremely cold weather and disease are of less importance. Understocking pasture and storing hay are perceived most effective as risk management options. 相似文献
