Câmara A. and Wang Y.‐H. ( 2010 ) introduce a simple square root option pricing model where the square root of the stock price is governed by a normal distribution. They show that their three‐parameter option pricing model can outperform the Black–Scholes option pricing model. We demonstrate that their assumption possesses an internal inconsistency in that the square root of the stock price can take on negative values. We generalize and revise their assumption so that the internal inconsistency can be avoided, and introduce a new square root option pricing model. The difference in option prices calculated from the two models may not be trivial. © 2011 Wiley Periodicals, Inc. Jrl Fut Mark 相似文献

This paper recounts the changing economic role of Chinese government, both at the central and local levels, in the reform process. The previously all-encompassing role of the central government has been greatly reduced, mandatory plans abolished, prices decontrolled, and administrative controls decentralised. Decentralisation has reoriented the interest of local governments towards reform and system innovation, fostered a climate for reform initiatives and spontaneous reform at local level, and induced competition among different localities that has again provided incentives for local governments to change, to adapt to changes, and to innovate. Decentralisation, however, has also led to dilemmas and problems, and created instability and uncertainty in China's macro-economic conditions and central-local relations. 相似文献

Los autores comparan las normativas sobre vacaciones y licencias susceptibles de facilitar el equilibrio entre vida profesional y familiar de Australia, Canadá, República de Corea, Estados Unidos, Europa occidental y Japón utilizando un índice compuesto para clasificarlas. Los Estados Unidos figuran en último lugar: la concesión de vacaciones anuales al trabajador no es obligatoria y las licencias por motivos familiares se limitan a 12 semanas al año. Este bajo nivel de reglamentación podría deberse, según los autores, a una concepción mercantilista del empleo sumada a la creencia de que empleador y trabajadores tienen idéntica capacidad de negociación, visión no compartida por las demás democracias industrializadas. 相似文献

Most firms tend to utilise various types of R&D collaboration partners simultaneously and partnerships between different types of partners show different properties. Thus, the effect of R&D collaboration may vary depending on partner types. This study considers four partner types: competitors, customers, suppliers and universities. It empirically examines the effect of R&D collaboration with each type of partner on product innovation, employing the Korean Innovation Survey data. Results show that R&D collaborations with customers and universities have a positive effect on product innovation, whereas R&D collaborations with suppliers and competitors have an inverted-U shape relationship with product innovation. This result can provide an explanation to the chaotic results of previous research and assist managers in selecting appropriate R&D partner. 相似文献

This note offers a generalization of Hausman and Taylor's equivalence of specification tests in the single-equation variance (error) components model to the two-factor multivariate variance components case. The relationship between the specification tests and the hypothesis test in the model proposed by Mundlak is also discussed. 相似文献

改革开放以来中国国民经济的持续快速发展,促进了城乡居民收入总体的不断提高,客观上也带来了经济利益在不同利益群体间的重新调整和分配及社会收入分层的加剧,居民收入差距在城乡、行业、地区之间的扩大,逐步成为现阶段收入分配领域的焦点问题。一些人把我国贫富差距拉大的原因归咎于没有建立起一套完善的税制,致使税收的调控功能没有有效发挥出来。笔者认为,这种说法是有失偏颇的。 相似文献

国防费:国防战略与宏观经济调控 总被引:1,自引:0,他引:1
国防支出对于一国经济增长有正、负两个方面的效应,如果处理得当,国防费对经济增长的正向效应是可以占主导地位的。合理地掌握它,可以建立巩固的国防体系用以保障国家安全和经济发展,调节社会总供给与总需求的均衡关系,推动科学技术的研究开发,促进经济增长。我国应加大财政支持国防现代化建设的力度,使我国国防费支出的绝对额和相对额都有实质性的增长,使中国成为名副其实的强国。 相似文献

Given the growing number of hotel brands, improving consumer experience has become an increasingly important area of interest to industry practitioners. The purpose of this study is to investigate the relationship between hotel guests' brand experience, knowledge and loyalty to name‐brand hotels. Confirmatory factor analysis and structural equation modeling with the incorporation of a second‐order factor analysis were employed to achieve the research goals. The findings indicate that brand experience was represented as a holistic concept with sensory, affective, behavioral and intellectual aspects. While brand experience influences brand loyalty, its impact is partially mediated by brand knowledge. This is a pioneer study that combines consumer experience with branding in the hospitality industry and offers practical suggestions to facilitate hotel managers in their development of effective branding strategies.
