韩国公务员财产申报制度的构建路径及对我国的启示

摘要：从二十世纪六十年代起，韩国为了根治日益严重的腐败问题开始了公务员财产申报制度建设，经过几十年的努力最终对财产申报制度成功立法，并取得了显著成效。我国应借鉴韩国经验，在领导干部财产申报制度建设过程中，循序渐进，逐步推进，注重配套制度建设，突出财产申报的核心环节，注重领导示范及细节规定，切实加强宣传教育，努力改善制度实施的环境，争取尽早立法。     

录井参数辨别岩性方法探讨

在使用PDC钻头或者是在斜井以及水平井钻井时,不能充分地利用返出的岩屑来准确反映地层岩性的变化情况,综合录井实践表明,随地层岩性的变化,各录井参数也随之变化。本文建立了识别地层岩性变化的录井参数相对变化率和绝对变化率模型,定量的探讨录井参数的变化与地层岩性的变化之间的对应关系,通过现场使用证实,该方法对于识别岩性及其变化具有重要价值。     

财务比率截面数据分布特征研究

财务比率截面数据分布特征对于财务危机预测、信用评级等具有基础性的意义。通过对沪深全部上市公司2000年至2006年8种主要财务比率年度截面数据分布进行拟合分析后发现,高达90%的财务比率截面数据的最佳拟合分布为非正态分布,原始比率数据中有近一半的比率服从对数逻辑分布;经过数据转换后,财务比率的对数逻辑分布特性更为显著。从不同年份间比率截面数据的记忆特性来看,流动性比率表现出完全的记忆,现金负债比率也表现出较强的记忆。通过数据转换或异常值剔除,可以显著提升财务比率数据的正态特性。

有机质入侵后土体压缩性状试验研究

为了模拟不同种类有机质入侵红黏土对土体物理力学特性的影响,在红黏土中添加腐殖酸、富里酸、腐殖酸钾3种外掺有机质配制得到了不同种类和含量的人工有机质土,并进行了液、塑限对比试验;然后,对红黏土和重塑有机质土进行室内侧限压缩对比试验,分析了有机质含量、有机质种类、初始含水率对有机质土体压缩性状的影响.试验结果表明:随着有机...     

Is the Annual Earnings Response Coefficient Statistically Significant in Brazil?

The aim of this paper is to analyze the significance of firm-specific and pooled earnings response coefficients in the Brazilian market. The lag structure of earnings-return relations is also analyzed. The sample consists of 61 Brazilian public firms that represent all firms with a minimum of seven continual data from 1995 to 2008. The analysis is based on linear regressions of two different proxies of earnings and two different proxies of return. The results show that, for firm-regressions, few companies presented a significant relationship between earnings and stock returns, and for some firms a negative coefficient was found. In the pooled regressions a positive and statistically significant coefficient was found, and the tests suggest that variance in cross-sectional observation is more relevant in explaining the earnings response coefficient than the time-series variance.     

Comparisons of robust tests for shifts in trend with an application to trend deviations of real exchange rates in the long run

We study the finite sample properties of tests for structural changes in the trend function of a time series that do not require knowledge of the degree of persistence in the noise component. The tests of interest are the quasi-Feasible Generalized Least Squares (FGLS) procedure by Perron and Yabu (2009b Perron, P and Yabu, T. 2009b. Testing for shifts in trend with an integrated or stationary noise component. Journal of Business and Economic Statistics, 27: 369–96. [Taylor &; Francis Online], [Web of Science ®] , [Google Scholar]) and the weighted average of the regression t-statistics by Harvey et al. (2009 Harvey, DI, Leybourne, SJ and Taylor, AMR. 2009. Simple, robust, and powerful tests of the breaking trend hypothesis. Econometric Theory, 25: 995–1029. [Crossref], [Web of Science ®] , [Google Scholar]), both of which have the same limit distribution whether the noise component is stationary or has a unit-root. We analyse the finite sample size and power properties of these tests under a variety of Data-Generating Processes (DGPs). The results show that the Perron–Yabu test has greater power overall. With respect to the size, the Harvey–Leybourne–Taylor test exhibits larger size distortions unless a moving-average component is present. Using the Perron and Yabu procedure to test for structural changes in the trend function of long-run real exchange rates with respect to the US dollar indicates that for 17 out of 19 countries, the series have experienced a shift in trend since the late nineteenth century.     

中美信用评级市场发展比较与启示

本文结合中美信用评级市场发展脉络,从评级机构、收费模式、监管模式等方面分析两国信用评级市场发展过程中的不同特征,认为美国信用评级市场健康发展的原因在于评级机构重视市场声誉以及监管机构注重加强引导与监管。借鉴美国经验,我国的信用评级机构应该注重加强信用评级机构的内部治理,提高信用评级机构的国内外影响力;同时加强外部环境建设和信息披露制度建设,建立科学统一的外部评级机构管理制度。
