This paper uses a reduced‐form approach to derive a closed‐form pricing formula for defaultable bonds. The authors specify the default hazard rate as an affine function of multiple variables which follow the Lévy jump‐diffusion processes. Because such specification allows greater flexibility in the generation of a valid probability of default, their pricing model should be more accurate than the valuation models in traditional studies, which ignore the jump effects. This paper also proposes a new method for estimating the parameters in a Lévy Jump‐diffusion process. The real data from the Taiwanese bond market are used to illustrate how their model can be applied in practical situations. The authors compare the pricing results for the influential variables with no jump effects, with jump magnitudes following the normal distribution, and with jump magnitudes following the gamma distribution. The results reveal that the predictive ability is the best for the model with the jump components. The valuation model shown in this paper should help portfolio managers more accurately price defaultable bonds and more effectively hedge their portfolio holdings. 相似文献

This paper uses a general two-sector model of endogenous growth to examine how the spirit of capitalism affects the relation between public finance and growth. The spirit of capitalism is defined as acquisitive personal objectives. We find that if the spirit of capitalism is present, an increase in the share of government spending in output reduces the long-run growth rate. The negative relationship between fiscal spending and growth is consistent with empirical evidence. 相似文献

In recent papers, Moon and Choi (1998) and Hariga and Ben-Daya (1999)considered a continuous review inventory model with a mixture of backordersand lost sales in which the lead time, the order quantity, and the reorder pointare decision variables was studied. Moreover, they also develop a minimaxdistribution free procedure for the problem. While the demands of differentcustomers are not identical in the lead time, then we can't only use a singledistribution (such as Moon & Choi (1998) and Hariga & Ben-Daya (1999))to describe the demand of the lead time. Hence, we correct and extend the modelof Moon and Choi (1998) and Hariga and Ben-Daya (1999) by considering thelead time demand with the mixture of distributions. In addition, we also applythe minimax mixture of distributions free approach to the model by simultaneouslyoptimizing the order quantity, the reorder point, and the lead time to devise a practical procedure which can be used without specific information on demand distribution. 相似文献

中国乡村公共品的提供:连带团体的作用 总被引:2,自引:0,他引:2
在威权和转轨体制下,民主和官僚政治制度通常很薄弱,为什么处于这种制度下的政府官员所提供的公共品,往往还超过了足够维护社会稳定所需的最低水平呢?案例研究表明,即使正式责任制度很薄弱,非官方惯例和规则的约束仍然能够促使当地官员设立并履行其公共责任。而这些非正式责任制度由特定类型的连带团体提供并在全社区发挥其道德权威。在其他条件都相同的情况下,存在这类集团的村庄比没有这类集团的村庄更有可能获得较好的公共品供应。 相似文献

This study develops a moderation model to examine the role of a proactive environmental strategy on eco‐innovation. Drawing upon the perspectives of contingency theory, this study argues that the impacts of sustainability strategy on eco‐innovation depend on market demand, innovation intensity and government subsidy. The sample used to test the hypotheses is obtained from the Community Innovation Survey in Taiwan. A total of 2955 manufacturing firms are included in the final sample. A logit moderating regression is adopted to analyze the models. The results reveal that market demand and government subsidy positively moderate the relationship between environmental strategy and eco‐innovation. Specifically, firms are more likely to adopt a proactive environmental strategy to improve eco‐innovation under high levels of market demand and government subsidy. Furthermore, the results indicate that innovation intensity affects the effect of environmental strategy on eco‐innovation, but the direction of the influence varies with different categories of eco‐innovation.

This paper constructed a pricing model for the asset with multi‐risks by specifying the risky factors (i.e., interest rate and termination hazard rates) to follow gamma distributions. The model not only avoids the possibility of the termination hazard rate taking an irrational (i.e., negative) value, but it also makes it easier to derive a valuation formula for a risky asset. Our model can also effortless apply because the parameters of the gamma distribution can easily be estimated from market data. An example using Taiwanese bond data illustrates how the model can be utilized for practical applications. To facilitate understanding of how accurately the different models price risky bonds, we compare their out‐of‐sample pricing errors for different hazard rate specifications assuming normal and gamma distributions. The results show that our pricing formula is realistic and accurate in its applications. Therefore, it should help market participants to accurately price risky assets and to effectively manage complicated portfolios. 相似文献

This study extended the research on the relationship between entrepreneurial self-efficacy and intention by developing a moderated mediation model. This model posits that the link between entrepreneurial self-efficacy and intention is mediated by attitudes toward entrepreneurship and planned entrepreneurial control, and that these mediation processes are further moderated by subjective norms. Based on a sample of 308 valid responses, regression analysis yielded two noteworthy results. First, entrepreneurial self-efficacy positively affects intention through attitudes toward entrepreneurship and planned entrepreneurial control. Second, the direct effect of entrepreneurial self-efficacy on intention decreases as subjective norms increase. By contrast, the indirect intention effects of entrepreneurial self-efficacy through attitudes toward entrepreneurship and planned entrepreneurial control increase as subjective norms increase. In addition, the results indicated that subjective norms positively affect entrepreneurial intention. These findings indicated that the model advances the use of the theory of planned behavior and can be used to define a person as an entrepreneur. 相似文献

The relationship-building approach, focused on the building of brand-to-consumer relationships conducive to brand loyalty formation, has become an extensively investigated topic in international brand management studies. However, the theoretical development of this approach manifests obvious diversities, causing managerial uncertainty about how to take appropriate strategic actions to put the relationship-building approach to best use. The current study, orchestrating the main concepts derived from three relationship-building paradigms with necessary adaptations and modifications, develops and validates the Relationship-Building for Strategic Brand Management Model. Its most noteworthy contribution lies in the coalescence of pragmatic utilitarianism, emotionalism and social symbolism, orienting the relationship-building approach to correspond to the principle of holistic consumer experience management. As explicated by the model, committed and attached relationships built upon the relationship foundation mirroring the holistic essentiality of holistic consumer experience are convertible into powerful driver of international brand loyalty. The model structure and causal path pattern prove to be applicable to different international product brand categories in different regions. Strategic implications are deduced from the research findings, which the international brand manager may take into consideration to maximize the effectiveness of relationship-building strategies for fostering brand loyalty in the international market. 相似文献

This paper applies a disaggregated approach to segment industrial markets under competitive structures taking the air-freight market for the high-technology product industry in Taiwan as a case study. Data from firms is used to examine the structure of the air freight industry and we find that carriers are clustered into two strategic groups, express and forwarder. Pricing is a leading strategy recognized by customers for forwarders, whereas service punctuality and freight security are the winning strategies for express. The high-tech freight market is classifiable by shipment destination and size. 相似文献
