在企业中,年功通常包含工龄(员工在组织中持续服务的时间长度)和年龄两个要素。强调年功的人力资源实践能否有效缓解员工的组织政治知觉,从而使员工安分守己,不会做出有损组织的行为,是一个值得探讨的问题。本文采用问卷调查法,以48家企业和918名员工的配对数据为样本,对这一问题展开了探讨。研究发现,年功导向人力资源实践能够有效降低员工组织越轨行为;同时,年功导向人力资源实践会促使员工形成较为保守和被动的策略倾向,产生保持沉默静待好处的组织政治知觉;并且,年功导向人力资源实践有助于缓解员工对其他个体自利行为的感知,以及在薪酬和晋升方面自己利益受到侵害的感知,从而降低一般政治行为的政治知觉以及薪酬和晋升政策的政治知觉;最后,年功导向人力资源实践能够通过使员工产生保持沉默静待好处的组织政治知觉,从而减少员工的组织越轨行为。研究结论为本土化人力资源实践的合理化解释提供了理论依据,扩展了对本土化人力资源实践影响效应的认识;同时也证明了组织政治知觉的跨文化差异性。  相似文献

We present a dual-process risk perception model that integrates cognitive and emotional as well as consequentialist and deontological components by distinguishing between two modes of evaluative processing: (a) a consequentialist evaluation that focuses on potential consequences and (b) a deontological evaluation that focuses on moral values. Each of these two modes is assumed to trigger specific cognitive evaluations, specific emotions, and specific behavioral tendencies concerning a perceived risk. We conducted an experiment (N = 270) that tested whether the relative dominance of the two evaluative modes would depend on the causal structure of the environmental risk being evaluated and on the social role of the evaluator. Three types of causal structure were varied by providing scenario information: (a) anthropogenic risks that endanger only nature, (b) naturally caused risks with potential harmful consequences for humans, and (c) anthropogenic risks that may harm humans. Participants evaluated each scenario from the perspective of one of three social roles: mayor, expecting parent, and environmental activist. For each scenario, participants specified their focus and evaluated the event’s morality and perceived risk, the intensity of specific emotions, and their preferences for prospective behaviors. Results showed that the consequentialist evaluation was generally stronger than the deontological evaluation and was less affected by the experimental manipulations. The deontological evaluation was substantially affected by the risk’s causal structure. It was stronger for anthropogenic than for natural causation; risks caused by humans were associated with greater perceived moral blameworthiness, more intense morality-based emotions (e.g. outrage), and a stronger tendency to perform agent-related behaviors (e.g. aggression) than naturally occurring risks. The effect of the social role was less pronounced than that of the causal structure. Furthermore, the effect of an evaluative focus on behavior was fully mediated by emotions for deontological evaluations and partially mediated for consequentialist evaluations. The implications for environmental risk perception and communication are discussed.  相似文献

The measurement of risk perception and risk attitudes, and their link to actual risk behaviors have been extensively discussed. However, the potential impact of perception of risk management instruments on the decision to use those instruments has rarely been addressed. This article hypothesizes that the degree of perception of insurance contracts and participation decisions could have substantial mutual influence depending on the development of the market. An empirical work is carried out based on a survey of data for paddy rice farmers in Hunan Province, China. It shows that the sampled farmers’ crop insurance perception was surprisingly low despite years of pilot programs and tens of billions of expenditure in government subsidies. The result of simultaneous equations model indicates that crop insurance perception and participation are simultaneously determined and mutually improving. Moreover, empirical evidence indicates that the impact of crop insurance participation on perception is slightly stronger than that of perception on participation, and thus provides weak evidence of a ‘learning-by-doing’ stage in China at present. Together with evidence of substantial local disparities in perception, implications for the Chinese government in further cultivating the crop and rural insurance market are discussed.  相似文献

This paper analyzes demographic determinants of incident experience and risk perception, as well as the relationship between the two, for eight different risk domains. Analyses were conducted by merging the results of a Swedish population-based survey, which includes approximately 15,000 individuals, with demographic and socio-economic register data. Being male was associated with higher incident experience yet a lower risk perception for nearly all risk domains. Lower socioeconomic status was associated with higher incident experience for falls, and being a victim of violence but lower incident experience for road traffic accidents. Lower socioeconomic status was also associated with higher risk perception for falls. On aggregate, ranking the different domains, respondents’ risk perception was in almost perfect correspondence to the ranking of actual incident experience, with the exception that the risk of being a victim of violence is ranked higher than indicated by actual incident experience. On a demographic group level, men and highly educated respondents perceive their risks to be lower than what is expected considering their actual incident experience.  相似文献

Climate change is a growing problem and has been highlighted as a global issue. Empirical evidence increasingly indicates its obvious potential risks to humans and society. As members of this society, business organizations face greatly diverse climate change-related risks that they must recognize and respond to. However, gaps exist between scientific evidence and the actions of business organizations. Few empirical studies have examined the business organizations’ actions taken in response to climate change in Korea. This paper addresses this critical gap in the climate change literature by examining business organizations’ behaviors and identifying the factors influencing their actions. We employ statistical models to compare corporate climate change actions, and we explain their variations using survey data. The results indicate that despite increasing concerns about climate change, businesses have implemented very limited precautionary mitigation and adaptation actions. In addition, the concerns of the businesses about future climate change impact, organizational capacity (leadership, staff capacity, existence of a relevant division or department), and business size are significant factors with respect to the implementation of climate change actions.  相似文献

创新是企业内涵式的增长方式,并购是企业外延式的增长方式。在资源有限的情况下,企业如何在这两种战略之间进行权衡?本文以2007-2018年沪深A股上市公司为研究样本,发现如果并购引起企业资产负债率增加,则会对并购后的R&D投资形成"财务侵占",从而对研发产生负面影响;这种抑制作用在主并企业存在融资约束的情况下会更加显著;按企业特征划分,这种抑制作用主要存在于小企业和民营企业。研究结果为基于边界条件的并购如何影响企业创新绩效提供了实证证据,同时也为企业进行相关战略变更和投资决策提供了有益参考。  相似文献

This ticle analyses the pre-emptive jump bidding equilibrium in takeover auctions when bidders’ valuations of the target firm follow truncated normal distribution. It shows that potential heterogeneity of the targets’ value, measured by the standard deviation of the bidders’ valuation function, is especially important when it is small and, for extremely small values, the second bidder is almost always pre-empted. It also shows that, contrary to regular clock-style auctions, the increase in standard deviation may negatively affect the expected profit of the first bidder.  相似文献

This research shows that the ACA health insurance exchanges have generated more merger activity in the health insurance market. The impact is robust to control for an extensive set of factors suggested by both neoclassical and behavioural frameworks. The economic impact of this ACA provision is substantial with 3.8 more months of unusually high merger activity or 52 more merger bids per year.  相似文献

The elimination of goodwill amortization in 2001 brought about significant change in how companies are required to account for goodwill. This change in accounting also brought with it new challenges for auditors, namely evaluating the reasonableness of management's assumptions related to goodwill valuation. In addition to introducing technical challenges, this task is particularly difficult given the misalignment in incentives it creates between managers who likely prefer to avoid recording an impairment and auditors who seek to minimize the bias in management's impairment testing. This study focuses on the consequences of the misaligned incentives that auditors face under the current goodwill assessment process. We find that the decision to record a goodwill impairment is associated with an increase in the probability of auditor dismissal. Consistent with the presence of significant friction with clients, our results also indicate that the likelihood of auditor dismissals is negatively related to the favorability of the impairment decision. Furthermore, we find that companies impairing goodwill prior to dismissing auditors subsequently employ auditors that are, on average, more favorable to clients in their impairment decisions.  相似文献
