Riding the swaption curve

We conduct an empirical analysis of the term structure in the volatility risk premium in the fixed income market by constructing long-short combinations of two at-the-money straddles for the four major swaption markets (USD, JPY, EUR and GBP). Our findings are consistent with a concave, upward-sloping maturity structure for all markets, with the largest negative premium for the shortest term maturity. The fact that both delta–vega and delta–gamma neutral straddle combinations earn positive returns that seem uncorrelated suggests that the term structure is affected by both jump risk and volatility risk. The results seem robust for macroeconomic announcements and the specific model choice to estimate the risk exposures for hedging.     

Corporate Stock and Bond Return Correlations and Dynamic Adjustments of Capital Structure

This paper analyses the effects of dynamic correlations between stock and bond returns issued by the same firm on the speed of adjustment towards target leverage. The results show that the estimated correlations are time varying, show persistence and differ among firms. Analysis of the potential explanatory variables reveals that the correlations decrease with negative expectations about future aggregate risks, but only for firms with a low default probability. In contrast, correlations are positively associated with specific risk measures, especially idiosyncratic stock risk and financial leverage. The positive relationship between the correlations and the leverage ratio suggests that target leverage can be achieved faster when the stock–bond correlation is high. Our results show that this is the case.

成本计量模式与企业成本控制机制研究

成本计量模式存在着制造环节、价值链与商业模式三个视角的划分,它们反映了不同成本效益对称情形,三者间具有层次演进性。从成本与利润的关系看,企业内部就是成本计量,利润则是市场角度的成本补偿计量,企业机制就可以视为在有意义的领域做出独特或某种与众不同的贡献而进行的成本流程安排。企业健康成本结构应该是一个开放的以接纳先进价值观的信息综合体。企业要获得可持续竞争力就必须树立科学的成本控制观念。     

发达国家对发展中国家的新直接投资

发达国家投资厂商对发展中国家的直接投资已发生了很大变化,传统直接投资以投资者持有足够股权对投资项目保持有效控制的活动方式,新直接投资是以其他方式不同程度地参与控制,或只参与收益分享而不参与控制。新直接投资是由传统直接投资、间接融资、纯国际贸易相结合而形成的国际经济活动,反映了投资的实质性特征。     

A Market and Spatial Perspective of Health Tourism Destinations: The Hungarian Experience

Since health tourism is one of the most popular and most dynamically developing products of modern tourism, this paper aims at studying the characteristic features of health tourism destinations from a regional and spatial perspective. Accordingly, the authors would like to introduce a new approach of spatial and product analysis of tourism where the market and spatial relations and relevance of health tourism were analysed through the example of Hungary. Although the classic medical tourism centres were established on natural medical water basis, by today, due to product diversification, continuous innovation and the involvement of medical services into health tourism, the geographical embeddedness seems to disappear, thus basically restructuring the market. The methodological novelty of the research is that exceeding the classic supply–demand algorithm, we compiled a complex viewpoint system adequate to the specialities of the given product characteristics. In our study, the authors intend to survey the special characteristics of health tourism focusing on medical destinations through Hungarian examples since the country's leading position in the global market is well recognized, including medical services.

居民货币需求的“结构性流动陷阱”及其对我国物价变动影响之研究

由于当前经济改革中的一些结构性问题使我国居民存在对货币需求的"结构性流动陷阱"."结构性流动陷阱"是我国近年来城乡居民储蓄存款高速增长的根本原因,也是对我国自1997年以来物价变动产生重要影响的一个基本因素.文章首先对当前转型期我国存在的居民货币需求"结构性流动陷阱"形成原因进行分析,其次,依据这个观点对我国近年来出现的通货膨胀和通货紧缩的基本原因和特点进行深入的分析和系统的研究,并就我国未来短期内物价走势进行分析和预测.     

论基于符号语义学的平面广告设计

就语义学特征而言,将视觉形象明显地区别于语言和其他传播形式的正是它们的标记性和形象性以及由此带来的视觉结构的不确定性特征,从平面广告角度说,视觉结构的相对不确定性在视觉说服中发挥着关键作用,更为视觉传播的形式和内客创新提供依据.     

旅游产业发展与居民消费结构——基于1994～2009年经验数据

旅游产业的发展和居民消费结构有重要的关联,研究居民消费结构的变化对旅游产业的发展具有十分重要的意义。通过对1994～2009年旅游消费和居民消费结构有关数据的分析,发现我国旅游消费的增长速度在不断放缓,导致旅游产业的发展可能面临瓶颈。城乡二元结构对旅游消费有重要影响,城镇居民旅游消费降低与住房、医疗和教育等支出有关,农村居民旅游消费可能会发展为新的增长点。     

中国外贸增长方式转变的评价指标体系与实证研究

从外贸规模、外贸结构、外贸效益、外贸可持续发展、外贸竞争力五个方面建立外贸增长方式及其转变的评价指标体系,以中国1995—2008年的数据,对外贸增长方式转变成效进行了实证研究表明,从总体上来看,外贸增长方式转变已有成效;规模指标显示外贸规模不断扩大;结构指标显示外贸结构在波动中优化,但优化程度与规模增长相比显得不足;效益指标、可持续发展指标、外贸竞争力指标,都有一定程度的上升。但贸易结构有待进一步优化,贸易条件需要进一步改善,环境、资源指标需要进一步提高,外贸增长方式转变的任务仍然十分艰巨。
