期刊参考文献著录格式的统计与分析——以湖北省期刊为例

以湖北省期刊为统计样本,分析《文后参考文献著录规则》（GB/T 7714—2005）的执行情况,针对其中存在的问题提出几点建议：人文社科类期刊要提高对参考文献著录规范的重视程度;不宜用注释代替参考文献列表;参考文献顺序编码制要优于著者-出版年制;文后列出的参考文献,在正文中必须对应标注;专业性较强的英文科技期刊可参照同专业的国际著名刊物进行参考文献著录。

Detecting Abnormal Bid-Ask Spread: A Comparison of Event Study Methods

This study examines empirical issues associated with the use of bid-ask spreads in event studies. The simulation results indicate that the distribution of average standardized abnormal spread shows little deviation from normality. Simulation results also indicate that the widely used percent spread metric results in test statistics with low power. In contrast, use of a standardized raw spread metric and a simple mean-adjusted expectation model results in well specified and reasonably powerful Patell and Brown-Warner type test statistics. As the abnormal spread series is characterized by high first order serial correlation, it is important to adjust for this serial correlation when using multi-day event windows.     

Capital and resolution policies: The US interbank market

We develop an empirically based simulation study to test two types of policies designed to control systemic risk: preventive policies targeting capital requirements and mitigation policies targeting default resolution. We find that capital buffers reduce both the number of defaults and the resulting losses. The loss reduction benefit increases as the magnitude of adverse shocks becomes higher. We find that a simple branch-breakup resolution strategy reduces the loss borne by the Federal Deposit Insurance Corporation (FDIC). The mitigation effect becomes higher as the fraction of assets resolved through auctions and auction competitiveness increase.

Testing equality of variances in the analysis of repeated measurements

The problem of comparing the precisions of two instruments using repeated measurements can be cast as an extension of the Pitman-Morgan problem of testing equality of variances of a bivariate normal distribution. Hawkins (1981) decomposes the hypothesis of equal variances in this model into two subhypotheses for which simple tests exist. For the overall hypothesis he proposes to combine the tests of the subhypotheses using Fisher's method and empirically compares the component tests and their combination with the likelihood ratio test. In this paper an attempt is made to resolve some discrepancies and puzzling conclusions in Hawkins's study and to propose simple modifications.
The new tests are compared to the tests discussed by Hawkins and to each other both in terms of the finite sample power (estimated by Monte Carlo simulation) and theoretically in terms of asymptotic relative efficiencies.     

复杂适应系统理论在股市模拟中的应用

资本市场是由金融产品提供者(如上市公司)、交易所和投资者组成的系统。随着经济的不断发展,股票市场已成为我国资本市场中最活跃、发展最快速的市场,因此它也成为众多专家学者研究的焦点。传统的金融学理论对于股票市场中许多普遍存在的特征性事实,如尖峰胖尾、波动聚集等现象难以解释。与此同时,传统的线性数学分析方法也陷入了前所未有困境。在环境的要求下,复杂适应系统理论在金融学中的应用所具备的优势逐渐显露出来。
