专利权价值评估的进一步探讨

在对现有专利权价值评估模型进行探讨的同时,又针对专利权的投入与产出均为随机的情况下,根据McDonald和Siegel是否继续生产期权计算公式,提出了修正期权定价法,作为对现有模型的补充。     

Efficiency measurement with multiple outputs and multiple inputs

This paper discusses modeling technical and allocative inefficiencies in both cost minimizing and profit maximizing frameworks with special emphasis on multiple inputs and multiple outputs. Both primal and dual models are considered for this purpose. In the primal approach we use a separable output and input function (the constant elasticity of transformation output function and Cobb-Douglas input function). The dual models assume translog cost or profit functions. Technical inefficiency is assumed to be random in the cross-sectional models, and fixed firm-specific parameter in the panel data models. Allocative inefficiencies are always treated as input-specific parameters. We derive exact relations linking technical inefficiency and allocative inefficiencies to cost and profit when the underlying technology is represented by a flexible functional form such as the translog. It is shown that appending a one-sided homoscedastic error term to model technical inefficiency, or neglecting technical inefficiency altogether in a translog profit tunciton results in model misspecification and inconsistent parameter estimates.     

REITs在商业地产发展中的运用

REITs是一种可以使广大中小投资者投资房地产并分享稳定收益的方式。随着我国房地产宏观调控政策作用的不断显现,房地产开发企业所面临的融资条件越来越严格。对于开发投资大,回收期长的商业地产开发来说,发展REITs具有重要意义,不仅能拓宽商业地产开发的融资渠道,还可以分散银行体系的经营风险,防范金融业风险。对国内商业地产开发中存在的问题和在商业地产中引入REITs时开发商应做的准备工作进行了讨论,同时结合美国REITs的经验提出了相关政策建议。     

论我国企业财务管理目标的现实选择

企业由于所面临的财务管理环境存在着差异，因而其财务管理的目标也并非是完全一致。所以．企业只有从自身的实际需要和客观条件出发，确定合理的财务管理目标。本文从现有的几种观点出发，探讨适合我国企业的切实可行的财务管理目标。     

外生冲击与房地产真实价格波动--对1998～2003年中国31省(市、区)的实证研究

文章首先根据经济学模型界定了两个重要指标:自相关系数与收敛系数.认为不同的外生冲击对这两个系数有不同的影响,而它们决定了房地产真实价格波动形态的差异.在此基础上,文章利用1998～2003年中国31个省(市、区)的面板数据对中国房地产市场进行了实证研究,其结论是,在真实人均可支配收入和真实建筑成本较高、真实税后住宅抵押贷款利率较低的地区有较大的自相关系数和较小的收敛系数,从而房地产真实价格具有更大的波动性.为使房地产真实价格在均衡价格附近平稳运行,降低开发成本和提高消费者购买成本能收到较好的效果.     

城市轨道交通的外部性对房地产的影响研究综述

城市轨道交通的外部性给房地产的发展造成巨大的影响,使沿线房地产得到增值,如何将这种外部效益转化为内部效益成为研究的课题.在综述了国内学者关于轨道交通对房地产外部经济性的研究成果,以及轨道交通与房地产联合开发的应用研究后,又结合我国实际,提出轨道交通应与房地产联合开发,实现双赢的建议.     

实际汇率、工资和就业--对中国贸易部门和非贸易部门的实证研究

在同时考虑贸易部门和非贸易部门的情况下,实际汇率贬值会增加贸易部门就业,但会减少非贸易部门就业,对实际工资的影响则是不确定的.按照理论分析的结果,文章对人民币实际汇率和中国两部门实际工资及就业的关系进行协整检验,结果发现:人民币实际汇率贬值显著增加贸易部门就业,但非贸易部门就业对实际汇率变动不敏感,而两部门的实际工资和实际汇率之间则都没有协整关系存在.进一步检验发现实际汇率变动对就业在贸易和非贸易部门之间的结构也没有影响.总的结论认为,即使考虑到非贸易部门,人民币实际汇率升值对整个就业也是不利的,而贬值有利于整个就业.     

INTEREG: A Twenty-region Input–Output Model for Italy

Since the regional scale turns out to be the scale at which fiscal devolution is likely to be accomplished in Italy, and that at which trade and growth interdependencies as well as regional convergence can be most conveniently investigated, a new 20-region input–output model for Italy seems to be a useful tool of analysis. Although various regional and interregional models have been constructed since the 1950s, none has been implemented for the whole system of 20 Italian administrative regions considered in their tight mutual dependence; also, the pool approach has not been greatly favoured, even in situations where direct information on regional trade is lacking. The main purpose of this paper is to report on the structure of the model, the rather complex procedure used in the model construction and the adopted solution technique. Some space is devoted to the problems encountered in handling regional trade endogenously in an input–output setting and to a comparison between the pool approach, used in the Italian model, and other current techniques. The paper also reports on some preliminary results regarding the regional impact of fiscal policy.
