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

In this paper, we first propose a multi-dimensional Bühlmann credibility approach to forecasting mortality rates for multiple populations, and then compare forecasting performances among the proposed approach, the CBD model, the Lee-Carter model (LC), the joint-k (JoK-LC), the co-integrated (CoI-LC), and the augmented common factor (ACF-LC) Lee-Carter models for multiple populations. Mortality data from the Human Mortality Database are fitted to the underlying mortality models for both genders of three well-developed countries (the US, the UK, and Japan) and both genders of a developed country (France) and a developing country (Poland) with an age span 25–84 and a wide range of fitting year spans. Empirical illustrations show that the proposed multi-dimensional Bühlmann credibility approach contributes to more accurate forecast results, measured by AMAPE (average of mean absolute percentage errors over all fitting year spans), than the CBD, LC, JoK-LC, CoI-LC and ACF-LC models for three forecasting year spans 2004–2013 (10-year wide), 1994–2013 (20-year wide) and 1984–2013 (30-year wide).  相似文献

This study integrates three methods for evaluating the interaction and importance of key factors, while mapping the differences between development and maintenance stages during the formation of marketing strategic alliances in the telecommunications industry. A systematic, quantitative, integrated measurement is proposed to evaluate the importance of factors. Moreover, it provides a holistic picture of similarities and differences across stages for establishing marketing strategic alliance relationships. The factors' evaluation results show that the maintenance stage is critical for the relationship as it relates to sustaining the collaboration and can determine whether a marketing strategic alliance will continue or terminate.  相似文献

As transportation is essential for tourism development, effectively utilizing its perishable resources has become an important issue. This study aims to analyse the relationship between airline fares and using conditions from the perspective of millennial tourists and taking the Taipei–Tokyo market as an example. The study attempts to show a revenue management practice in the manipulation of homogeneous seat service and give millennial tourists a better understanding of their preferences for ticket choices. We categorize availability of flight, advance booking, ticket validity, and changing conditions as main attributes and develop a stated-preference questionnaire with multiple hypothetical scenarios for respondents to select in the experiment. We effectively collect 390 valid samples for a mixed logit analysis and the results show that all applied attributes are statistically significant. Ticket validity is revealed to be the most important fence with the largest willingness-to-pay value and followed by availability of flight, advanced booking, and changing conditions.  相似文献

We examine the performance of U.S.‐based foreign and global funds after controlling for their regional and style exposure. We show that, on average, the total performance (TP) and security selection abilities of both foreign and global funds are significantly negative and exhibit short‐term predictability. Additionally, R2 reflects funds’ security selection abilities, consistent with previous findings for domestic mutual funds. Investors can earn higher abnormal returns and TP in the short run by purchasing past winners with low R2 than by purchasing past losers with high R2. However, there is no evidence of predictability in the funds' region‐shifting and style‐shifting abilities.  相似文献

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 explored tertiary hospitality students’ attitudes and overall perceptions about green and sustainable practices; and how these may impact their future career paths in the hotel industry. A thematic analysis with data from 12 semi-structured interviews with students in a hotel management school in Australia was used to identify patterns and interpretive themes. Results revealed positive attitudes among Generation Y hospitality students towards working in a green and sustainable hotel environment. Implications highlight the need for sustainability education in the curriculum of tertiary education providers and strong emphasis on sustainability practices in employee training programs. The results also suggest possible impacts of sustainability practices in recruiting and hiring in the hospitality industry and how this may affect future hospitality employees and leaders.  相似文献

Engaging in collaboration may be the best way for a firm to enhance its competitive advantages, since this can offer faster access to both resources and capabilities. This study aims to develop a framework for making collaboration partner choice decisions. The authors design a strategic game model of collaboration using Miles and Snow typology. An empirical data set collected from the S&P COMPUSTAT database is adopted to verify the model, and several managerial implications are derived. This model helps a company choose a competitor as a collaborative partner and helps in the selection of a collaboration strategy.  相似文献

To advance theoretical understanding of consumer engagement on social media, this cross-cultural study evaluates how culture influences consumers’ engagement levels and activities on brand pages of social network sites. It further evaluates the underlying motivations and engagement mechanisms in two culturally distinct countries, China and the USA. Specifically, social media dependency, parasocial interaction, and community identification are examined as the key antecedents of consumer-brand engagement. The results confirm the effects of the proposed antecedents and reveal both cultural differences and similarities between Chinese and American consumers’ engagement with brand pages on social network sites.  相似文献

To shed cultural insights on the complex interplay between globalization and local ideologies, this study presents an online experiment that tested the comparative effects of global and local consumer culture positioning strategies in China. Reflecting the prevailing trend of nationalism around the globe, the study findings highlight the power of consumer nationalism on driving the effects of these culture-oriented positioning strategies. Furthermore, self-brand connection was found to be a critical mediator of the effects of consumer nationalism on brand evaluation. Based on the findings, this study provides strategic guidelines for both domestic and global brands to craft culturally relevant campaigns that capitalize on the growing trend of consumer nationalism in transitioning markets such as China.  相似文献
