区域金融扭曲差异真的会一直促进FDI流入吗?

随着我国FDI流入量的逐年上升,现行金融体系能否适应外资的大量流入,已成为国内外学者关注的焦点.本文以我国1990～2007年间28个省区数据为样本,采用System GMM分析金融扭曲差异对FDI流入的影响.实证研究发现:在1990～2007年,我国总体上以及东部、中西部的金融扭曲差异显著地促进了外资的流入.在1990～1999年,我国总体、东部金融扭曲差异对FDI流入起显著地促进作用,而中西部对外资流入的作用不明显.在2000～2007年,我国总体、中西部金融扭曲差异显著促进了外资流入;而东部金融扭曲差异对FDI流量的作用不明显,却显著地抑制了外商直接投资存量的增长.因此,地区金融扭曲差异不会一直显著地促进FDI流入.     

试论民俗旅游中文化差异对主客交往的影响——以永定客家土楼民俗文化村为例

主客交往是旅游研究中的重要领域,而国内相关研究寥寥无几。文章在总结了相关研究文献的基础上,以一个民俗旅游景区为例,讨论了文化差异对主客交往的影响。研究证明,文化差异对主客交往既有促进作用,也有阻碍作用。在文化背景相差较大的情况下,文化差异对主客交往主要起阻碍作用。而在主客文化背景相差不大的情况下,文化差异对主客交往主要起促进作用。

Estimation of regression parameters in generalized linear models for cluster correlated data with measurement error

Liang and Zeger (1986) introduced a class of estimating equations that gives consistent estimates of regression parameters and of their asymptotic variances in the class of generalized linear models for cluster correlated data. When the independent variables or covariates in such models are subject to measurement errors, the parameter estimates obtained from these estimating equations are no longer consistent. To correct for the effect of measurement errors, an estimator with smaller asymptotic bias is constructed along the lines of Stefanski (1985), assuming that the measurement error variance is either known or estimable. The asymptotic distribution of the bias-corrected estimator and a consistent estimator of its asymptotic variance are also given. The special case of a binary logistic regression model is studied in detail. For this case, methods based on conditional scores and quasilikelihood are also extended to cluster correlated data. Results of a small simulation study on the performance of the proposed estimators and associated tests of hypotheses are reported.     

On best affine prediction

The theory of best affine prediction (BAP) is extended to the vector case with possibly singular variance matrix of the predictor variable. The theory is then applied to derive Thomson’s classical predictor for factor scores, allowing for a singular variance matrix of the factors. The results are formulated in a free distribution setting. Further, Bartlett’s estimator is considered and compared with Thomson’s predictor. The authors are thankful to the two referees, one for a suggestion that led to the Addendum of the paper, and the other one for several very useful remarks.

Comparison of telephone RDD and online panel survey modes on CPGI scores and co-morbidities

The purpose of this study was to compare the influence of two survey modes – telephone random digit dialling (RDD) and stratified sampling of an online panel – on Canadian Problem Gambling Index (CPGI) scores and co-morbidities. An identical gambling survey was administered to 4000 South Koreans selected via random dialling of cell phone numbers and to 4330 South Korean members of an online panel. The online panelists were found to have significantly higher levels of tobacco use, drug or alcohol problems and mental health problems, higher employment status and lower happiness levels. However, even when controlling for these variables, CPGI scores for the online panel were significantly higher than those for the telephone interview. This appears to be due to higher levels of pathology among online panelists combined with potentially more valid self-reports due to enhanced anonymity.     

Some linear and nonlinear rank tests for competing risks models

Using the methods of asymptotic decision theory asymptotically optimal for translation and scale families as well as for certian nonparmetric families. Moreover, two new classes of nonlinear rank tests are introduced. These tests are designed for detecting either “ omnibus alternatives ” or “ one sided alternatives of trend ”. Under the null hypothesis of randomness all tests are distribution - free. The asymptotic distributions of the test statistics are derived under contiguous alternatives.     

Rank Tests for Two-Sample Problems Based on Multiple Type-II Censored Data

In this article, we study the effect of censoring on the asymptotic efficiency of the two-sample rank tests based on multiple Type-II censored data. Since the scores generating functions associated with these test statistics have a finite number of jump discontinuities, we use a slightly modified version of a theorem of Dupac and Hajek (1969 Dupac , V. , Hajek , J. ( 1969 ). Asymptotic normality of simple linear rank statistics under alternatives II . Ann. Math. Statist. 40 : 1992 – 2017 .[Crossref] , [Google Scholar]) to obtain their asymptotic distributions under fixed alternatives. This modified version, which leads to a simpler centering constant, is proved by Dupac (1970 Dupac , V. ( 1970 ). A contribution to the asymptotic normality of simple linear rank statistics . In: Puri , M. L. , ed. Nonparametric Techniques in Statistical Inference . Cambridge : Cambridge University Press . [Google Scholar]) in the light of results of Hoeffding (1968 Hoeffding , W. ( 1968 ). On the Centering of Simple Linear Rank Statistics. Instit. Statist. Mimeo Series No. 585, University of North Carolina . [Google Scholar]), an earlier version of Hoeffding (1973 Hoeffding , W. ( 1973 ). On the centering of simple linear rank statistics . Ann. Statist. 1 : 54 – 66 .[Crossref], [Web of Science ®] , [Google Scholar]). Hence, we obtain the Pitman ARE's of these rank tests relative to the corresponding tests based on the complete samples. The ARE's are computed for some well known rank tests for two-sample location and scale problems, when the combined ordered samples from different underlying distributions are censored using triple and lower order Type-II censoring schemes. The effect of all these censoring schemes on the ARE's of the different tests is examined numerically. It is found that there is a gain in efficiency due to censoring in many of the cases considered here. This suggests that in such cases it is possible to improve the efficiency of rank tests by discarding suitable portions of the data.     

第三世界妇女的现实经验与西方女性主义思想的张力——浅析斯皮瓦克的女性主义

斯皮瓦克的研究让英语世界的读者熟悉了法国女性主义,但是同时她又质疑以法国女性主义为代表的西方女性主义。以西方女性主义自我为中心来解释妇女面临的问题,界定妇女的政治目标,忽略了妇女之间所存在的种族与阶级差异,遮蔽了第三世界妇女的经验。
