农民生活型环境行为对农村环境的影响

农民环境行为对农村环境的影响具有直接性、根源性,农村环境问题是广大农民生产和生活活动直接作用的结果.农民的环境行为可以划分为生产型环境行为和生活型环境行为,二者互动互构,形成农村环境问题的内在生成机制.目前,学术界还很少关注农民日常生活行为对环境的影响.研究将以环境行为为研究视角、以日常生活为切入点,分析农民日常生活行为对环境的影响,建构一个农民生活型环境行为的分析框架,为解决农村环境问题、促进农村生态环境建设提供新思路、新途径.     

领地性对员工创新行为的影响机制——以知识隐藏和不信任为连续中介

本文以知识隐藏与同事不信任为连续中介,从个体层面探究了领地性对员工创新行为的消极影响机制。通过对221份员工与员工、员工与直接管理者配对的样本数据进行分析,结果表明:(1)领地性正向影响知识隐藏和同事不信任感,负向影响员工创新行为;(2)知识隐藏中介领地性对同事不信任的影响;(3)同事不信任中介知识隐藏对创新行为的影响;(4)知识隐藏与不信任连续中介领地性与员工创新行为之间的关系。本研究结合自我延伸理论和社会交换理论,揭示了领地性对创新行为的消极作用,研究结论对于管理员工领地性、减少知识隐藏与不信任关系,以及促进创新行为具有重要意义。     

Herding behavior in the Pakistan stock exchange: Some new insights

This study attempts to examine the presence of herding behavior in the Pakistan Stock Exchange (PSX). The novel contribution of this paper is that it investigates the herding phenomenon from a large number of facets such as herding of firms towards market, herding of firms towards industry portfolios, herding of industry portfolios towards market, herding in mostly traded stocks and in large and small stocks, and herding in the crisis period. For this purpose, we use the herding behavior model of Christie and Huang (1995) on the daily closing prices data of 609 firms listed on the PSX from January 2004 to December 2013. Results show that individual firms do not herd towards market index, except when the market experiences a negative return of 5%. However, when we sort firms into small and large groups based on median market capitalization, results indicate that large firms show herding behavior in extreme market movements. Further, we find that firms in several industries herd towards their industry portfolios. However, we find weak evidence of industry portfolios herding towards the market. We also segregate the impact of financial crisis of 2008 from normal times. These findings support results of our baseline estimation.     

试析西方经济学“经济人”假设的发展及其局限性——基于对马克思相关观点的理解

"经济人"假设关注个人的利益目标及实现目标的能力,而马克思在刻画个人时还特别强调了社会关系对个人行为选择的约束。笔者立足于对马克思相关观点的理解,探讨秉承斯密个人主义思想的西方经济学流派对"经济人"假设的继承和发展,试图揭示这一个人观念进一步发展遇到的困惑。遵循方法论个人主义原则,西方学者要从追逐自身利益的"经济人"出发,解释约束其实现自身利益的因素形成和变迁的原因,从而不得不面对引入另一种个人行为模式的尴尬。     

The intertemporal risk-Return relation,investor behavior,and technical trading profits: evidence from the G-7 countries

The intertemporal risk-return relation and investor behavior are both important pricing factors that jointly determine the expected market risk premium. Using the price adjustment process as a control variable, we find that the intertemporal risk-return relation is positive conditional on bad market news, but is non-positive conditional on good market news. This implies that good (bad) market news weakens (strengthens) the positive risk-return relation. The pattern in the distortion of the risk-return relation is consistent with short-term mispricing in which investors overvalue (undervalue) the stock market in reaction to good (bad) market news. We also show that ignoring the price adjustment process in the estimation of the risk-return relation leads to model misspecification and induces an upward (downward) bias in estimates of the relative risk aversion parameter conditional on good (bad) news. Our model of the asymmetric risk-return relation along with the price adjustment process is capable of generating the return dynamics that is attributable to technical trading profits. We suggest that the profitability of technical trading rules is not a violation of market efficiency, but a consequence of trading rules exploiting the asymmetric effect of price changes on the risk-return relation, along with the persistence property of price changes.     

Regular economies with ambiguity aversion

We consider a family of exchange economies with complete markets where consumers have multiprior preferences representing their ambiguity aversion. Under a linear independence assumption, we prove that regular economies are generic. Regular economies exhibit enjoyable properties: odd finite number of equilibrium prices, local constancy of this number, local differentiable selections of the equilibrium prices.Thus, even if ambiguity aversion is represented by non-differentiable multiprior preferences, economies retain generically the properties of the differentiable approach.     

民族地区集市交易行为的非经济因素分析——以湘西墟场集市为例

集市作为民族地区市场体系中的基层市场,在人们日常的生产和生活中发挥着重要的作用。笔者以湘西民族地区墟场集市为研究案例,以集市交易行为为研究起点,以非经济因素这一新颖性的角度来进一步研究民族地区市场问题。研究认为民族地区集市的运行更多的受到少数民族的伦理道德、文化习俗以及意识形态等非经济因素的影响。

When profession trumps potential: The moderating role of professional identification in employees’ reactions to talent management

Abstract

This study aimed to investigate the role that a professionalized context plays in shaping employee reactions to talent management decisions. We examined the mediating role of felt obligation in the relationship between talent ratings and organizational citizenship behavior. Further, the study tested whether professional identification moderates the relationship between talent ratings and felt obligation towards the organization. Five hundred and ninety-eight teachers that had recently received ratings of their talent status responded to a survey questionnaire. Felt obligation mediated the relationship between talent ratings and organizational citizenship behavior. Furthermore, professional identification moderated the relationship between ratings of potential and felt obligation in such a way that the relationship was strongest for the teachers expressing the lowest professional identification. At high levels of professional identification, the relationship was not significant. These results indicate that conventional talent management might be less effective for increasing favorable attitudes and behaviors among employees in highly professionalized contexts, such as the education sector.     

Towards a hybrid model? A systematic review of human resource management research on Chinese state-owned enterprises (1993–2017)

Abstract

Over the past two decades, there has been a proliferation of research on human resource management (HRM) in Chinese state-owned enterprises (SOEs) as a result of the wide-reaching state-sector reform of the late 1980s. This article aims to provide a systematic review of literature on this topic and capture the nature of HRM in Chinese SOEs, both in research and practice. The article draws on 178 studies from 43 English academic journals over a period of 25?years (1993–2017). In analysing this literature and by taking stock of theoretical frameworks, research methods, themes and analysis of academic articles in this area, we have gained a number of insights. The study has found that the research methods used have shifted from qualitative and interpretive methodology toward quantitative and sophisticated modelling. A further insight is that there has been a relatively heavy reliance on institutional theory in the earlier studies reviewed, and since then a switch towards organizational behaviour perspectives. The level of analysis has moved from macro to micro level and thematic foci have become more diverse and complex. We highlight a number of avenues, theoretical and empirical, for future studies in this field.
