关于出境游组团社互为代理运作模式的探讨

随着组团社的激增，出境游市场的竞争日趋激烈，国家旅游局提出了出境游组团社之间互为代理的市场运作设想。本文对出境游组团社互为代理的内涵、必要性和可行性进行了探讨，并借助中性联合品牌和电子商务网络，从互为代理的市场运作流程、质量保障体系和财务结算等方面初步构建了出境游组团社互为代理的市场运作模式，以期为在全国范围内推行互为代理提供一个初步的市场运作框架。     

基于平衡计分卡的项目管理绩效评价模型研究

传统的项目管理往往仅将其管理领域局限于项目与项目实施间的行为,缺乏与组织战略相互因应的结合。以项目为导向(Project-base)的组织中,通过员工之间的互相支持,资源共同分享的方式,使企业能够快速地应变不同的需求与变动,动态的调整项目的分配,从而强化企业的竞争优势。本文的研究目标是试图采用平衡计分卡的模式作为项目管理与组织战略结合的桥梁,摆脱传统上单纯以量化模式评估绩效的方式,而从多个层面针对项目管理的绩效作一个较为全面的探讨,期望能使项目管理的绩效与组织战略更加紧密结合。通过平衡计分卡四个层面的绩效评价,充分地分析组织整体与项目个别的绩效表现,提供管理人员快速发现问题与制定决策的依据。     

资本流动、货币供给与价格总水平--一个理论分析框架

在国际收支的货币主义理论背景下，资本流动与货币供应量之间是一个循环反复的作用过程，二者的相互作用在内部经济与外部经济取得新的均衡时结束。借助IS—LM—BP模型可以将这种复杂的循环作用过程以及作用结果通过图形进行演绎。固定汇率制度下资本不完全流动时的IS—LM—BP模型与开放经济下的AS—AD模型分析表明，在固定汇率制度下，资本流出对国内货币供应量有紧缩效应，并使价格总水平下降；相反，资本流入对国内货币供应量有扩张效应．使价格总水平上升。

Interest-only and principal-only mortgage strips as interest-rate contingent claims

Interest-only (IO) and principal-only (PO) mortgage strips are valued in a stochastic interest-rate environment. The prepayment rate of the underlying mortgages is affected by two considerations not present in the pure financially rational model: (1) The property owner's holding period is assumed to follow a Gamma distribution, resulting in the possibility of prepayment due to the sale of the property (i.e., prepayment that is too early based on market interest rates); and (2) borrowers are assumed to face heterogeneous transaction costs related to refinancing the existing mortgage, and delay refinancing when market conditions make it optimal to do so (refinancing too late). Properties of IO/PO strips are identified by the finite difference method.     

Economic Risk Factors and Commercial Real Estate Returns

A great deal of research has focused on the links between stock and bond market returns and macroeconomic events such as fluctuations in interest rates, inflation rates, and industrial production. Although the comovements of real estate and other asset prices suggests that these same systematic risk factors are likely to be priced in real estate markets, no study has formally addressed this issue. This study identifies the growth rate in real per capita consumption, the real T-bill rate, the term structure of interest rates, and unexpected inflation as fundamental drivers or state variables that systematically affect real estate returns. The finding of a consistently significant risk premium on consumption has important ramifications for the vast literature that has examined the (risk-adjusted) performance of real estate, for it suggests that prior findings of significant abnormal returns (either positive or negative) that have ignored consumption are potentially biased by an omitted variables problem. The results also have important implications for dynamic asset allocation strategies that involve the predictability of real estate returns using economic data.     

The Lévy LIBOR model

Models driven by Lévy processes are attractive because of their greater flexibility compared to classical diffusion models. First we derive the dynamics of the LIBOR rate process in a semimartingale as well as a Lévy Heath-Jarrow-Morton setting. Then we introduce a Lévy LIBOR market model. In order to guarantee positive rates, the LIBOR rate process is constructed as an ordinary exponential. Via backward induction we get that the rates are martingales under the corresponding forward measures. An explicit formula to price caps and floors which uses bilateral Laplace transforms is derived.
