流动性约束下我国居民消费行为的二元结构与地区差异

本文构建了状态空间模型和跨省面板数据模型,就不确定性和流动性约束等对我国居民消费行为影响进行比较分析,结果表明:1978年以来,收入的不确定性对城镇居民消费行为的负面影响要大于农村居民;城镇居民面临的流动性约束相对小于农村居民;城镇居民面对利率的替代效应要大于收入效应,而农村居民与之相反。1995年以来,收入和支出的不确定性对我国居民整体消费行为的影响并不显著,但与东中部地区居民消费变动正相关;我国居民消费面临的流动约束整体来看并不严重,但中部地区居民相对而言面临更强的流动性约束。     

公众注意力影响买入行为吗？——基于投资者行为的分析

公众注意力衡量了一只股票受投资者关注的广泛程度。本文分析了公众注意力对不同类型投资者买入行为的影响,发现小投资者更倾向于买入引起他们注意的股票,中大类型投资者没有明显与注意力相关的买入行为,机构投资者则表现出了与公众注意力相关的策略性行为。小投资者的这种特性使得他们更容易成为市场操纵的受害者,对此本文提出了相应的政策建议。

How does the effect of pre-play suggestions vary with group size? Experimental evidence from a threshold public-good game

Numerous studies have examined factors influencing the likelihood of cooperative outcomes in nonzero-sum games, but there has been little study of the interaction between two of the most important: group size and pre-play cheap talk. We report results from an experiment in which groups of size between 2 and 15 play a one-shot multi-player threshold public-good game. In our random leader treatment, all group members select a suggestion (e.g., “Everyone should choose X”), with one randomly chosen to be broadcast to the group. In a choice only treatment, subjects choose suggestions but none is sent, and in a baseline treatment, there are no suggestions at all. We find a negative interaction between group size and this kind of communication: the beneficial effect of both suggestions overall and cooperative suggestions on cooperation, cooperative outcomes, and payoffs decreases sharply as the group size increases. We find a similar negative interaction in a follow-up treatment in which all group members’ suggestions are broadcast to the group. Our results suggest that care should be taken in generalising conclusions from small-group experiments to large groups.     

Information and Investor Behavior Surrounding Earnings Announcements

The goal of this paper is to analyze the impact of annual earnings announcements on the market through the order flow data in addition to the usual transaction data. In this respect, examining order flow data can potentially reveal valuable information that is not available from transaction data. In fact, the data allow us to test hypotheses about asymmetric information and investor behavior and to test if the behavior varies with investor sophistication. In addition, the paper tries to identify the determinants of the impact on a firm's value using assumptions about investor behavior.     

Public Leadership: A review of the literature and framework for future research

Abstract

This study analyses and reviews the literature on public leadership with a novel combination of bibliometric methods. We detect four generic approaches to public leadership (i.e. a functionalist, a behavioural, a biographical and a reformist approach) which differ with regard to their philosophy of science (i.e. objective vs subjective) and level of analysis (i.e. micro-level vs multi-level). From our findings, we derive four directions for future research which involve shifting the focus from the aspect of ‘leadership’ to the element of ‘public’, from simplicity to complexity, from universalism to cultural relativism and from public leadership to public followership.     

谦卑型领导行为、组织公民行为与团队效能关系

领导行为影响团队效能。探讨了谦卑型领导行为对团队效能的影响,系统分析了组织公民行为在谦卑型领导行为与团队效能间的中介作用。通过问卷调查和统计分析,研究发现,谦卑型领导行为与团队效能显著正相关,谦卑型领导行为的3个维度都对团队绩效、团队承诺有显著正向影响;开门纳言、欣赏他人对团队满意度有显著正向影响。领导开门纳言、欣赏他人对组织公民行为有显著影响,而组织公民行为又显著影响团队绩效、团队满意度与团队承诺;组织公民行为在开门纳言与团队绩效、开门纳言与团队承诺关系间起完全中介作用,在开门纳言和团队满意度关系间起部分中介作用,在欣赏他人与团队效能关系间起部分中介作用。     

Is the leadership style important in R&D departments in Spanish industrial companies? An empirical analysis

This paper aims to thoroughly look into the effects of the differences between the diverse leadership styles on innovative outputs (intensive, efficient and eco-efficient) in Spanish industrial companies. A questionnaire for the factories was sent and was received between the months of September 2013 and June 2014. A total of 142 valid questionnaires were received. Several regression models were used in the empirical analysis. The results show that charismatic leadership positively induces an intensive innovative output, at the same time as it improves firms’ eco-efficient innovative output. Likewise, the individualised consideration that characterises transformational leadership makes this leadership style produce positive results on the whole group of innovative outputs considered. At the other end of the leadership spectrum, the transactional style causes negative effects on the relationship between innovative activity and innovative outputs, and more specifically, on the efficient innovative output.     

技术权力、组织间信任影响领导行为的跨案例研究

在技术创新网络中,非对称的技术权力和不同程度的组织间信任引致了核心企业对合作企业采取不同领导行为。从心理定位视角出发,基于技术权力和组织间信任两个变量提出核心企业的4种领导行为——技术锁定、技术防御、技术扶持与技术标准,通过跨案例研究,分析论证了这4种领导行为,并对合作过程中核心企业的领导行为进行了科学解释,以帮助合作企业科学预测领导行为,进而提高运行绩效和网络地位。     

A股、H股市场羊群行为实证研究

本文采用分散度指标和偏离度指标对2005-2008年间交叉上市A股和H股市场的羊群行为进行了实证检验．发现A股市场存在羊群效应,但未发现H股市场上的羊群效应。本文认为两地市场在投资者理念、市场结构、信息披露、政府监管方面的差异是造成这种差异的根源,并在此基础上提出了政策建议。本文的研究将对企业在两地市场上投融资,各类投资者规避风险获得稳定收益,两地金融市场的一体化乃至中国资本市场的长远发展具有一定指导意义。
