On the performance of the ordinary least squares method under an error component model

Starting from the one-dimensional results by Wang et al (1994) we consider the performance of the ordinary least squares estimator in comparison to the best linear unbiased estimator under an error component model with random effects in units and time. Upper bounds are derived for the first-order approximation to the difference between both estimators and for the spectral norm of the difference between their dispersion matrices.     

Impact evaluation for tourism development using the fuzzy set model: A case study of Kyongju,Korea

The Community tourism industry is primarily influenced by facilities, traffic systems, capacity, and development of tourism commodities. To develop tourism industry on a local basis, it is unavoidable to make investments on a large scale. Factor analysis for impact evaluation prior to undertaking of development projects, which this study intends to make, is more reasonable when related to the fuzzy numeric analysis of words or sentences than to a quantitative analysis of measured information. In this study the Euclidean distance method and Zadeh's fuzzy extension principle were used as linguistic approximation to establish the validity of decision‐ making in each factor category of impact degree. Therefore, this study introduces a general concept of Fuzzy theory through literature review of linguistic expressions. This study examined availability of the Fuzzy model in analyzing investment priorities for tourist development and applied it to Kyongju area, which unveiled the priorities for Kyongju tourism future in order of traffic system improvement, early construction of horse‐ racing track now under planning, promotion of Kyongju as tourism special zone to visitors and positive tourism events. In terms of methodology, this study disclosed that Fuzzy Model approach is greatly useful to decision‐making processes in tourist development.

普惠金融的反贫困效应研究——基于西部地区的面板数据分析

本文基于2005~2015 年西部12 省市（区）数据,测度普惠金融发展水平、贫困程度,运用面板数据实证检验普惠金融的反贫困效应,研究表明：（1）西部地区普惠金融发展水平整体较低,发展速度缓慢,省际差异明显;（2）西部地区的扶贫开发取得了明显效果,贫困程度较轻;（3）从普惠金融的各个维度看：金融服务覆盖率、金融服务可得性以及金融资源的实际使用效率对贫困均有明显的减缓作用;（4）普惠金融对西部地区反贫困效应整体显著,但分省效果并不明显。最后,就发展普惠金融以减缓西部地区的贫困现状提出相关的政策建议。
