Limit theorems for multivariate discrete distributions

According to the usual law of small numbers a multivariate Poisson distribution is derived by defining an appropriate model for multivariate Binomial distributions and examining their behaviour for large numbers of trials and small probabilities of marginal and simultaneous successes. The weak limit law is a generalization of Poisson's distribution to larger finite dimensions with arbitrary dependence structure. Compounding this multivariate Poisson distribution by a Gamma distribution results in a multivariate Pascal distribution which is again asymptotically multivariate Poisson. These Pascal distributions contain a class of multivariate geometric distributions. Finally the bivariate Binomial distribution is shown to be the limit law of appropriate bivariate hypergeometric distributions. Proving the limit theorems mentioned here as well as understanding the corresponding limit distributions becomes feasible by using probability generating functions.     

论我国环境保护中的路径依赖与超越

我国环境保护中存在着严重的路径依赖现象,且更多地表现为路径依赖Ⅱ.形成这种状况的主要原因是传统的发展模式、既得利益集团的压力和巨大的沉没成本等.要超越路径依赖,必须进行相应的技术和制度创新.     

How CEO hubris affects corporate social (ir)responsibility

Grounded in the upper echelons perspective and stakeholder theory, this study establishes a link between CEO hubris and corporate social responsibility (CSR). We first develop the theoretical argument that CEO hubris is negatively related to a firm's socially responsible activities but positively related to its socially irresponsible activities. We then explore the boundary conditions of hubris effects and how these relationships are moderated by resource dependence mechanisms. With a longitudinal dataset of S&P 1500 index firms for the period 2001–2010, we find that the relationship between CEO hubris and CSR is weakened when the firm depends more on stakeholders for resources, such as when its internal resource endowments are diminished as indicated by firm size and slack, and when the external market becomes more uncertain and competitive. The implications of our findings for upper echelons theory and the CSR research are discussed. Copyright © 2014 John Wiley & Sons, Ltd.     

广东省旅游业依赖度与经济增长关系的空间态势

运用面板数据的计量分析法,以广东省21个地级市、珠三角、东翼、西翼和山区为基本分析单元,利用2000—2011年旅游业依赖度、经济增长等多个指标面板数据,从不同的空间尺度对旅游业依赖度与经济增长关系进行分析,并探讨其形成机制。研究表明:广东省和山区旅游业依赖度与经济增长之间呈现倒U型曲线关系,其他三个区域二者关系并不显著;采用固定效应模型分析二者关系成因,发现对旅游业依赖达到一定程度时,旅游业对制造业产生抑制作用,导致"荷兰病效应",对技术创新投入水平产生挤出效应,增加政府干预,弱化制度质量,其中阻碍制造业发展是最主要的传导途径,但旅游业发展会促进人力资本和物质资本投入水平的提高。最后,结合得出的结论,提出发展意见。     

Youth Poverty,Employment, and Leaving the Parental Home in Europe

This paper studies the nature of youth poverty dynamics in Europe. First, it analyzes to what extent experiencing poverty in a given period is in itself positively related to the probability of living below the poverty line again in the future. That is, we assess the degree of poverty genuine state dependence among young people. Second, we study the interrelationships between poverty, employment, and residential emancipation. The results show that youth poverty genuine state dependence is positive and highly significant, but this scarring effect is short‐lived in Scandinavia compared to Southern or Continental Europe. Moreover, although we find a strong association between poverty and leaving home in Nordic countries, time spent in economic hardship does not last long. On the contrary, in Spain and Italy, young adults tend to leave their parental home much later in order to avoid falling into a poverty state that is more persistent.     

SDR货币篮子中人民币的国际化定位——汇率市场波动传染与波动聚类的实时甄别

随着人民币国际化进程的逐步推进,SDR货币篮子中人民币的国际化定位引人瞩目。本文基于非线性MSBIARCH模型,实时甄别人民币市场与美元市场、英镑市场、日元市场、欧元市场之间的波动传染关系,以及波动传染作用下汇率市场的波动聚类态势,进而识别SDR货币篮子中人民币的国际化定位,旨在为及时防范并规避人民币市场的波动风险提供参考。研究发现,汇率市场经由“经济基本面”“市场情绪”以及“市场预期”对外发挥波动传染作用,人民币市场与美元市场之间存在双向波动传染关系,与英镑市场、欧元市场以及日元市场之间存在单向波动传染关系。不同汇率市场之间的波动传染关系表现出时间区制转移特征,汇率市场的波动聚类态势也呈现时变特征。汇率市场发挥波动传染作用的时间与汇率市场呈现波动聚类态势的时间相匹配,均集中在极端经济事件期、不规则事件期以及政策颁布事件期。国际汇率市场的波动传染作用导致了人民币市场的波动聚类态势,而人民币市场的波动传染作用仅强化了国际汇率市场的波动聚类态势,SDR货币篮子中人民币的国际化程度有待进一步提高。     

Women’s Roles on U.S. Fortune 500 Boards: Director Expertise and Committee Memberships

This study examines the presence and roles of female directors of U.S. Fortune 500 firms, focusing on committee assignments and director background. Prior work from almost two decades ago concludes that there is a systematic bias against females in assignment to top board committees. Examining a recent data set with a logistic regression model that controls for director and firm characteristics, director resource-dependence roles and interaction between director gender and director characteristics, we find that female directors are less likely than male directors to sit on executive committees and more likely than male directors to sit on public affairs committees. There is little if any evidence of systematic gender bias in director assignment to other board committees. We find some evidence that boards evaluate resource dependence differently for women than men. Craig A. Peterson Western Michigan University, Grand Rapios, MI 49503, USA Craig A.

开放经济下的产业安全问题探析

本文认为,随着经济全球化进程的不断深化,开放经济、引进外资已经成为发展中国家促进本国经济发展的基本国策。但是如果不加限制地扩大外资的规模也会产生负面影响,即出现产业控制倾向,进而引发产业安全问题,这是事关国家经济安全的重大问题。对产业安全问题的研究,无论在现实经济运行还是在理论研究中,都具有非常重要的意义。随着国家经济结构的调整和产业升级的进程,产业安全的内涵和外延也将会有所拓展,金融安全、能源安全、网络安全、幼稚产业保护、经济结构、产业结构调整等都将成为产业安全研究所应关注的问题。     

The combined effects of dependence and relationalism on the use of influence in marketing distribution systems

This study uses data from the automotive replacement tire industry to test the proposition that dependence and relationship structure interact to determine frequency of influence-strategy use in distribution systems. The findings support the expectation that dependence is positively associated with recommendations, information exchanges, promises, requests, legal pleas, and threats. However, increases in dealer dependence increase the use of requests, legal pleas, and threats only in systems characterized by trivial levels of relationalism.The authors would like to express their gratitude to John Burnett, Robert Dwyer, Jule Gassenheimer, and Allen Wilhite for their helpful comments on this project.
