Social network contingency,symbolic management,and boundary stretching

A firm's structural position within corporate networks may affect the extent to which it engages in boundary stretching practices. Since social norms support low CEO compensation, offering high CEO compensation in China can be seen as a boundary stretching practice. Setting up a compensation committee (CC) may be viewed as a form of symbolic management in China. We argue that firms operating within central corporate network positions opt to pay higher CEO compensation without engaging in symbolic management. On the other hand, firms operating in structural hole positions tend to either pay lower CEO compensation or use CCs as a symbolic management tool in order to pay higher CEO compensation. Our hypotheses are largely supported based on 7,618 firm‐year observations in China. Copyright © 2013 John Wiley & Sons, Ltd.     

苯及其衍生物的密度泛函理论研究

采用密度泛函理论B3LYP/6-31G*方法对苯及其衍生物进行结构优化,并对其稳定性、电荷布局、振动频率进行分析讨论。结果表明:当苯环上的一个氢被-CH3、-NH2、-OH、-OCH3取代后,其结构稳定性依次增强;邻对位碳原子具有较高的负电荷,所以邻对位易于发生亲电取代反应;取代基为-CH3的C-H伸缩振动向短波方向移动,-NH2、-OH、-OCH3使C-H伸缩振动向长波方向移动。找到了苯及其衍生物之间存在的规律,为实验研究提供理论指导。     

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.     

Knowledge and Technology Transfer Relationship between a Research Center and the Production Sector: CIMAT Case Study

This article presents a study of the adoption of a knowledge and technology transfer model at the Center for Research in Mathematics in Guanajuato state, Mexico, in order to define the model that would produce the best outcomes for establishing a transfer relationship with industry, the government, and academia. The transfer of organizational models and practices is a phenomenon that occurs frequently in dynamic globalized organizational contexts that underpin ongoing quests for greater and faster development, while also adapting and exchanging innovative products and services. This article presents theoretical input from specialized entities and authors focused on knowledge and technology transfers at universities and research centers. The methodological strategy used in these research projects adopts a qualitative approach, with the study of an explanatory case study being the methodological tool, together with document analyses and semi-structured interviews. After the results have been obtained, the mechanisms used by the Center were identified for relating to the production sector, noting that this relationship involves high-level direct transfers. Positive outcomes were found that benefitted the Center and the company studied, underscoring the importance of government research centers having a knowledge and technology transfer model allowing identification of the contextual, technical and structural conditions that shape underlying transfer relationship at this Center, as well as the surrounding regions.

Marriage,cohabitation and women's response to changes in the male wage structure

Using microdata and grouped data that cover the period 1996 to 2006, we assess the extent to which cohabiting women adjust their labour supply to a lesser extent, if any, than married women in response to changes in male wages. Both microdata regressions and grouping estimators unambiguously indicate that cohabiting women respond less to variation in male wages than married women. However, the magnitude of the difference is not sizeable. We also assess the magnitude of married men's and cohabiting men's own wage elasticities and find that they do not differ much. Combined with the fact that male earnings account for roughly two-thirds of family earnings, these two findings explain why the impact of changes in male wages on family earnings is very similar for married couples and cohabiting couples: in both cases, a 10% decline in male wages appears to induce roughly a 6% drop in family earnings.     

Multidimensional risk and risk dependence

Evaluating multiple sources of risk is an important problem with many applications in finance and economics. In practice this evaluation remains challenging. We propose a simple non-parametric framework with several economic and statistical applications. In an empirical study, we illustrate the flexibility of our technique by applying it to the evaluation of multidimensional density forecasts, multidimensional Value at Risk and dependence in risk.     

基于SFA的我国汽车制造业技术效率的研究

本文以我国汽车制造行业为研究对象,选取10家具有代表性的汽车制造企业2000-2009年的面板数据,运用随机前沿分析(SFA)模型,实证研究了我国汽车制造企业的技术效率。研究结果表明,我国汽车制造业的技术效率总体呈波动趋势;客车、重卡企业技术效率最高,乘用车企业次之,轻卡、农用车企业最低;东部地区技术效率高于中部和西部;技术效率影响因素方面,库存过高、研发人员过多以及汽车产量过大不利于技术效率水平的提高,而企业与供应商和客户关系的加深,能提高企业的技术效率水平。

我国上市公司财务预警机制实证方法研究综述

财务预警机制,即搜集企业经营活动与成果的数据并设置为具有敏感性的指标体系,是对企业可能面临的财务危机实施的实时监控与预测警报。企业作为一国宏观经济的微观主体,其经营过程的顺畅与否直接决定整个国民经济的经济效益与发展速度,如何构建科学有效、误判率低的多元动态财务预警机制能系统地防范甚至解决财务危机的发生,对作为微观主体的企业、中观行业以及宏观国民经济都是急需解决的课题。
