How social distance affects the intention and behavior of collaborative consumption: A study based on online car-hailing service

In recent years, advances in mobile communications technology have enabled collaborative consumption or product sharing between consumers on a large scale. Unlike traditional consumption, collaborative consumption is based on collaboration among individuals, so that the decision-making mechanisms of individual consumers may be different from those in traditional consumption scenarios. The current study focuses on how the social distance between consumers and drivers affects collaborative consumption intention in the case of online car-hailing services. In this study, the theory of planned behavior (TPB) is used as the foundational framework, and we innovatively add the concept of social distance to the TPB to form a new, and integrated model. We test the model based on data collected from 315 online car-hailing users. The results shows that behavioral attitudes, subjective norms, and perceived behavioral control, positively influence collaborative consumption intention and behavior. More interestingly, we find that social distance has both direct and indirect impacts on collaborative consumption intention: The greater the social distance, the lower the collaborative consumption intention. Moreover, social distance also moderates the influence of subjective norms and perceived behavioral control on collaborative consumption intention. To be specific, the influence of subjective norms and perceived behavioral control on collaborative consumption intention is weakened when consumers perceive less social distance. The results suggest that the integrated model has a stronger explanatory power on collaborative consumption behavior. This study enhances the traditional TPB model and offers insight into promoting collaborative consumption in the context of the sharing economy.     

Do leveraged warrants prompt individuals to speculate on stock price reversals?

Using proprietary data on bank-issued knock-out warrants written on a stock index, we find that individual investors’ aggregate warrant portfolio speculates against the short-term trend of the index. We argue that contrarian trading is driven by the interaction of product design and investors’ preference for large leveraged positions. Investors tend to open larger positions whenever warrants offer higher leverage. As a result, investors open an aggregate long position when calls offer higher leverage than puts. Since knock-out leverages move systematically with the underlying, aggregate warrant positions become contrarian even if investors do not intend to speculate on reversals.     

基于Moran过程的PPP项目承包商机会主义行为演化动态

在PPP项目中，由于政府部门和承包商的目标不一致以及信息不对称等原因的存在，使得在其全寿命周期过程中，承包商的机会主义行为屡见不鲜。本文基于随机演化博弈理论，建构基于Moran过程的博弈模型，旨在探讨推动PPP项目承包商不采取机会主义行为策略的有利条件。研究表明，承包商数目不断扩大，通过降低承包商之间的举报成本，增大惩处力度，可使降低机会主义行为发生概率的效果显著。进一步，借助数值算例，对研究结果进行验证并给出相应的管理对策。     

化肥价格变化对粮食价格的影响研究--基于省际动态面板数据模型的系统GMM检验

基于我国粮食价格与化肥价格变动趋势的分析,运用2006年~2017年省际动态面板数据模型和系统GMM方法,实证检验了化肥价格变动对粮食价格的影响。结果表明:化肥价格变动对粮食价格存在显著的正向影响,在考虑化肥价格影响下,农业生产服务、种子等农资价格对粮食价格也存在显著的正向影响,机械化农具和农药价格对粮食价格不显著,"价补分离"政策对粮食价格存在显著负向影响。因此,在化肥减量行动背景下,适度调控化肥价格,避免化肥价格上升挤占粮农利润,大力发展农业生产性服务业和种子业,继续实行"价补分离"政策,提高补贴精准性,减少农民投入成本。     

网购食品消费者选择行为的影响因素

利用1 790份网络调查问卷数据,采用相关分析、交叉分析等统计方法,研究网购食品消费者选择行为,分析网购食品市场渗透率不高、用户黏性不足的主要原因,结果表明,消费者个性特征差异会导致对网购食品的不同态度,进而影响消费者对网购食品的选择行为;良好的网购环境、物美价廉的食品、优质的网购服务,是促使消费者选择网购食品的主要因素,对网购食品安全的担忧、习惯于传统购物方式、网购维权难度大,是抑制消费者选择网购食品的主要因素,尤其是网购食品"难维权、维权难"可能会放大消费者对网购食品产生的消极态度。为此,应加强网购食品多主体协同监管,消除消费者怀疑心理和不放心态度;建立以消费者需求为中心的网购食品质量安全供应链管理体系,推动线上市场和线下实体店紧密结合、融合发展;完善网购食品维权制度,畅通维权渠道。     

Representatives of future generations as promoters of sustainability in corporate decision processes

Current protests of the young generation emphasize that interests of future generations should be taken more into account by policy makers and in corporate decision processes. As organizations contribute to enduring environmental and social problems, they are required to promote sustainability in order to preserve options for the well-being of future generations. However, organizational decision makers often take a short-term perspective and neglect investments in intergenerational justice. Previous theoretical work has acknowledged the importance of representing future generations in today's decision-making processes to adopt a long-term perspective in order to promote intergenerational justice. In a laboratory experiment, we show that appointing representatives of future generations at the organizational level can foster investments in intergenerational justice. Although this outcome is more pronounced when aligned with the representatives' individual incentives, it even persists for a representative who is monetarily penalized for advocating the interests of future generations.     

员工企业社会责任感知影响人力资源管理效能？—基于领导行为的协同中介

通过对贵州、广东和福建3个省80家企业1148名员工进行调研,基于员工对企业社会责任、领导行为感知对人力资源管理效能带来积极影响为研究问题构建了一个中介模型。企业社会责任在组织微观层面的内涵越来越得到企业的重视,实现了员工的企业社会责任由产出需求转向投资视角,成为企业满足员工工作需要和工作资源的参照标准体系,有利于提升企业人力资源管理效能。本文研究发现:企业社会责任分别从企业经济责任、法律责任、伦理责任和自行裁量责任影响人力资源管理效能;变革型领导和交易型领导对企业社会责任和人力资源管理效能具有协同中介作用。研究结论对于企业社会责任、领导行为和人力资源管理三者匹配具有重要的理论和现实意义。     

Exploring the interdisciplinary potential of the Agenda2030—Interactions between five Danish societal demands for sustainable land use

This article explores the potential of the SDG framework for interdisciplinary research. The aim is to illustrate the process of creating a shared platform of operation by the clarifying the positive and negative interactions between societal demands for land use on a national and local level. The research question is answered by making use of the systemic approach introduced by Niklas Luhmann including his arguments about autopoietic communication systems reproducing themselves. An interdisciplinary research group is firstly applying the SDG framework to the demands for sustainable land use by activating the land consolidation in Denmark. By doing so a ‘national framework’ anchored in the SDG framework is created. Secondly, the national framework is applied to a multifunctional land consolidation project in a Danish case area. The findings from the mapping of interactions between societal demands on a concrete case area revealed that some indicators and societal demands are more prone to conflicts than others but also on the local level there may be variations. Thus, a localised and contextualised SDG framework has shown useful insight for future projects on sustainable land use including land consolidation projects. The paper concludes that the SDG framework may be used for facilitating interdisciplinary research, however there is also a need for guidelines and examples on how to integrate the framework in academia. The paper offers a suggestion for integrating the Agenda2030 and the SDG framework in projects about sustainable land use.     

THE ECONOMIC AND BEHAVIORAL CONSEQUENCES OF ONLINE USER REVIEWS

Online user reviews have become an increasingly relevant informational tool during product search and adoption. Recent surveys have shown that consumers trust and rely on online reviews more than they do on website recommendations and experts opinions. As a new way of driving consumer purchasing intentions, online user reviews have therefore come under scrutiny by researchers. The objective of this paper is to offer an overview of the literature regarding the impact of online user reviews on economic indicators (e.g., sales, marketing strategies) and on consumer behavior. Furthermore, following the growing interest of academics and professionals alike on the topic, the present work provides an exploratory analysis of the consequences of online reviews on individual rating behavior – empirical regularities showed that online rating distributions tend to be concentrated on extreme values, possibly because of rating biases. As consumers and firms incorporate the heuristic cues from such distributions into their decision-making processes, biased ratings might lead to suboptimal choices. This overview presents established results (e.g., the impact of volume on product sales) and insights as issues for future research.
