大股东控制下的股权再融资决策

不对称信息条件下,股权再融资的选择方式和认购量能作为信号向外部投资者表明公司的质量.本文发现:公开增发发行成本较高且大股东持股比例较小时,存在唯一的分离均衡,此时高质量公司定向增发,低质量公司配股;当公开增发成本较高且大股东持股比例较大时,定向增发是唯一的混同均衡;当公开增发成本较低且大股东持股比例较小时,公开增发是唯一的混同均衡.模型预测定向增发的公告效应为正,配股的公告效应为负,而公开增发的公告效应不明确,这与大量实证文献相吻合.     

发展中大国的金融发展与经济增长——基于规模效应的分析

近年来,发展中大国在其宏观经济诸多方面均表现出强劲的上升趋势。该发展浪潮往往被归因于规模效应——凭借规模经济、范围经济和聚集经济效应等导致了生产率的提高。通过将金融发展的特征嵌入到已有的增长和规模效应理论中,可以检验发展中大国金融发展和经济增长之间的关系,分析其产出、投资、贸易以及金融之间的相互关联效应,从而把握发展中大国的总体发展趋势。在金融危机发生时,经济刺激政策更应该倾向于贸易和投资领域,而不是金融领域,也就是说,在发展中大国,金融发展对经济的刺激作用非常明显地低于贸易和投资两个最重要的实体经济领域。     

Large Deviation Principles for Sequences of Maxima and Minima

In this article, we consider sequences of i.i.d. random variables and, under suitable conditions on the (common) distribution function, we prove large deviation principles for sequences of maxima, minima and pairs formed by maxima and minima. The i.i.d. random variables can be either unbounded or bounded; in the first case maxima and minima have to be suitably normalized.     

公司信息透明度与大股东资金占用研究

本文以2002-2006年非金融类的中国A股上市公司为研究对象,分析了公司信息透明度与大股东资金占用之间的关系.研究发现,在控制其它影响因素条件下,公司信息透明度越差,大股东资金占用问题越严重.该研究结论表明,提高公司信息透明度将有助于改善大股东与中小股东之间的信息不对称,缓解二者之间的代理冲突,减少大股东资金占用的可能性.

A new approach for disclosure control in the IAB establishment panel—multiple imputation for a better data access

For micro-datasets considered for release as scientific or public use files, statistical agencies have to face the dilemma of guaranteeing the confidentiality of survey respondents on the one hand and offering sufficiently detailed data on the other hand. For that reason, a variety of methods to guarantee disclosure control is discussed in the literature. In this paper, we present an application of Rubin’s (J. Off. Stat. 9, 462–468, 1993) idea to generate synthetic datasets from existing confidential survey data for public release.We use a set of variables from the 1997 wave of the German IAB Establishment Panel and evaluate the quality of the approach by comparing results from an analysis by Zwick (Ger. Econ. Rev. 6(2), 155–184, 2005) with the original data with the results we achieve for the same analysis run on the dataset after the imputation procedure. The comparison shows that valid inferences can be obtained using the synthetic datasets in this context, while confidentiality is guaranteed for the survey participants.     

Using Archival Datasets to Study Adoption-Related Questions

ABSTRACT

The Research Digest column describes the contents, availability and methods of accessing large datasets suitable for adoption research. With data collected by or funded by a variety of federal government agencies, the accessibility of these archival datasets enables researchers to pursue some of their investigative interests without all the problems related to data collection. Most of the data are relatively new, having become available to the public only in the 1980s. Secondary analysis of adoption-related material in these datasets could yield valuable insights into important adoption research questions.     

Robust Methods—Some Examples of Their Use

We describe several analyses in which robustness considerations have proved relevant. These examples exhibit the importance of (a) graphic displays as aids to formulating a preliminary model; (b) summary statistics that reduce the influence of outliers, that (c) give added opportunities of detecting relationships, and (d) are not unduly sensitive to granularity in the observations; and (e) techniques that pay due attention to anomalies in the data that superficially may appear to be negligible but that can obscure important effects. Finally, we make some general comments on the advantages and disadvantages of robust methodology.     

Large deviation for negatively dependent random variables under sublinear expectation

Abstract

In this article, first we give the definition of negatively dependent sequence of random variables under sublinear expectation then we establish large deviation principle for this kind of sequence. Moreover, we obtain the upper bound of moderate deviation principle.
