Comparing the Accuracy of the Minimum-Variance Grid Method to Multiple Regression in Appraised Value Estimates

The adjustment-grid method and the multiple-regression method are the two most frequently used techniques in the sales comparison approach. This paper demonstrates that although both techniques provide unbiased estimators, the minimum-variance grid estimator should result in a smaller standard deviation than the multiple-regression estimator. A technique is also derived to estimate the confidence interval or to perform hypothesis tests for the minimum-variance grid estimator.

Futures market equilibrium under Knightian uncertainty

This paper examines the effects of Knightian uncertainty on a commodity futures market within the Newbery‐Stiglitz framework. It is shown that Knightian traders act more conservatively. In a partial trade equilibrium, risk aversion and Knightian uncertainty have qualitatively similar effects on the equilibrium price and the equilibrium trading volume. Full‐trade and no‐trade equilibria are likely to prevail when the producer and the speculator incur different Knightian uncertainty. Herein different impacts of risk aversion and Knightian uncertainty are observed. © 2003 Wiley Periodicals, Inc. Jrl Fut Mark 23:701–718, 2003     

Provincial Motor Vehicle Taxation in Indonesia

Vehicle-based taxes are collected by provincial governments in Indonesia and constitute their most important source of locally collected revenue. This paper evaluates the structure and revenue performance of the two vehicle-based taxes–-the vehicle registration tax and the vehicle transfer tax–-focusing in particular on their allocative efficiency. This is evaluated in terms of their potential to meet road maintenance resource requirements, and the study finds that objectives other than allocative efficiency have determined the structure of the two taxes.

中国制造业上市公司多元化经营与企业价值研究

上市公司多元化溢价或折价问题一直是学术界研究的焦点,本文选取上市的704家制造企业作为样本空间对这一问题进行分析,发现定性上可以认为多元化有利于企业价值的提升,但是在定量上来看这种提升无法通过显著性检验,而且不同的衡量多元化的指标与不同的衡量企业价值的指标之间得出的结论很可能不同,因此如何选取相应的衡量指标应该是相关研究的首要问题。     

DBASEⅢ中数值算法的实现

ＤＢＡＳＥⅢ，是一个数据库管理系统，但在数值计算上很弱，本文举出一些实例说明如何在ＤＢＡＳＥⅢ上实现数值计算上一些典型算法，同时也给出ＤＢＡＳＥⅢ的一些编程技巧。     

生态文化旅游的价值评价研究

旅游业已经成为现代经济增长一个新的亮点,特别是生态文化旅游的增长速度更是惊人,而其发展的价值平衡是生态学和经济学必须面对的一个难题。本文依据意大利经济学家帕累托的不均匀分布定律,运用埃奇渥斯盒状分析图,在某一选定的生态资源环境的承载量既定的基础上,从生态文化旅游的价值交换的角度考虑,并且从定性研究转向定量研究,分析研究生态文化旅游的价值帕累托最优曲线,用以筛选生态文化旅游的工程项目。
