管理者过度自信、市场竞争与商业信用

基于行为金融视角,考量沪深两市2007～2011年上市公司管理者过度自信与商业信用的关系。结果表明,管理者过度自信与提供的商业信用正相关。民企面临的市场竞争大于国企,使得过度自信的管理者会提供更多的商业信用,而国有企业不存在这样的关系;同时,在竞争行业与管制行业之间,也表现出这种显著性关系。     

股权结构与企业股利政策选择关系:理论与实证分析

本文从公司治理视角出发,以中国上市公司为样本,对股权结构与企业股利政策关系进行了理论与实证分析。结果表明,管理者持股比例、股权集中度(包括第一大股东持股比例)与现金股利支付率显著正相关;国有股比例与现金股利支付率正相关;法人股比例和流通A股比例对现金股利支付率的影响可能是负向的,且极不显著。     

The impact of R&D on value added for domestic and foreign firms in a newly industrialized economy

This study compares the impact of R&D on value added between domestic and foreign firms in Singapore. The analysis is based on a comprehensive panel database from 1993 to 1999 provided by the Singapore Government. Our results found that R&D investments of foreign firms generated higher value added than those of domestic firms, and that the difference in value added contributed by R&D was moderated by the type of R&D and the technological level of industry. The study supports the argument that the ownership advantages possessed by foreign firms, relative to domestic firms, have positive effects on R&D performance.     

浅谈所有权保留

在现代商品交易活动中，赊销、分期付款已成为非常普遍的交易方式，在这种交易方式中如何保护出卖人利益成为合同法理论和实践中的重要课题。本通过对合同法第134条关于所有权保留制度的阐述，论述了所有权保留的含义、客体、登记及当事人权利义务等内容，希对买卖合同实务有积极的指导意义。     

Using mixed methods designs in the Journal of Business Research, 1990–2010

The purpose of this article is to examine the uses of mixed method research designs published in the Journal of Business Research. This study involves a content analysis of 2072 articles published between 1990 and 2010 in the Journal of Business Research. Seventeen mixed method studies implemented data collection procedures sequentially (68%), six implemented them concurrently (24%), and two combined both sequential and concurrent procedures (8%). On the whole, priority skews more toward quantitative strands with ten articles prioritizing quantitative data (40%), three articles prioritizing qualitative data (12%), and twelve articles prioritizing both equally (48%). Business scholars recognize the benefit of mixing qualitative and quantitative research; however, as a discipline, we are not demonstrating knowledge of the mixed method literature or procedures; none of the articles recognized or mentioned knowledge of mixed method procedures or cited mixed method research. This study provides guidance for researchers in identifying design types appropriate for various research objectives as well as the models of different design types appearing in the Journal of Business Research.     

Moments of Compound Mixed Poisson Distributions

Recursive formulae are derived for the evaluation of the moments and the descending factorial moments about a point n of mixed Poisson and compound mixed Poisson distributions, in the case where the derivative of the logarithm of the mixing density can be written as a ratio of polynomials. As byproduct, we also obtain recursive formulae for the evaluation of the moments about the origin, central moments, descending and ascending factorial moments of these distributions. Examples are also presented for a number of mixing densities.
