食品安全规制能提高生产者福利吗？——基于不同规制强度的检验

食品安全规制涉及政府、生产者和消费者三方利益主体的博弈。已有文献主要关注政府规制对减少生产者违规概率、提升食品安全水平和消费者福利所产生的作用。本文从生产者福利视角考察企业参与食品安全规制是否存在“收益率溢价”效应，以此对中国食品安全规制的间接效果进行实证检验。首先采用倾向得分匹配模型考察食品安全规制对企业资产收益率的平均影响效应，然后采用广义倾向得分匹配模型和门槛模型进一步考察不同规制强度与企业资产收益率的非线性关系。研究表明，当前食品安全规制对参与规制企业产生了“收益率溢价”的间接效果,但随着规制强度的扩展，企业资产收益率呈现先上升后下降的“倒U型”变化，具有显著的双重门槛特征，当企业持有4项质量认证证书时为“最优规制强度”。最后结合当前中国实际，解释了上述结论产生的原因及政策含义。     

The effects of power on consumers’ evaluation of a luxury brand's corporate social responsibility

This paper examines how power affects consumers’ responses to corporate social responsibility (CSR) initiatives of luxury brands. The results of three studies show that high‐power individuals evaluated a luxury brand's CSR campaign more positively than low‐power individuals. High‐power individuals viewed CSR activities as being more fluent than low‐power individuals. This study further demonstrates that power influences consumers’ responses to nonluxury brand's CSR activities. Low‐power individuals, who are more receptive to warmth, evaluated nonluxury brand's CSR more favorably rather than high‐power individuals.     

归因偏差视角下旅游行为失范成因研究

游客旅游行为失范时有发生,威胁着旅游资源与环境安全。心理归因影响个体行为逻辑,归因偏差是解释心理归因的经典理论。本文引入归因偏差理论,采用实证方法探究旅游行为失范背后的归因偏差因素,为减少旅游行为失范提供心理学依据。研究发现,归因偏差能够引致旅游者心理认知偏差,后者直接引发和助推旅游行为失范。心理环境和群体心理对引致旅游者的心理认知偏差和行为失范具有显著作用,归因偏差成为旅游者弱化旅游行为失范结果的心理屏障,可激发或促进旅游行为失范的发生或持续。研究认为旅游地可从完善硬件监控、控制游客流量、强化失范行为负面教育、发挥在场监督作用等方式削弱归因偏差效应。     

Effects of individual resources and team-member exchange on service quality

While workplace resources are generally viewed as positively affecting performance, some studies indicate that not all resources increase performance. This study addresses the controversial disparate effects of workplace resources on performance by exploring functionally classified workplace resources in self-managing service teams and their relative impacts on team service quality. Considering membership dynamics and consequences between members, a field experiment was conducted in a cafeteria, with data collected through a working diary for workplace resources and a customer survey to evaluate service quality. Results suggest that efficacy-resources in self-managing teams should be controlled with caution as they may adversely affect team service quality. Supporting the person–situation interactionism perspective, workplace resources interact dynamically with individual employees and with situations. Esteem-resources were found to increase team service quality, while team-member exchange not only improved team service quality but also moderated the impact of esteem-resources on team service quality.     

Climate for conflict management,exposure to workplace bullying and work engagement: a moderated mediation analysis

The present study investigates a potential preventive factor in relation to workplace bullying. Specifically, we examine how climate for conflict management (CCM) may be related to less bullying, increased work engagement, as well as whether CCM is a moderator in the bullying engagement relationship. The study was based on a cross-sectional survey among employees in a transport company (N = 312). Hypotheses were tested simultaneously in a moderated mediation analysis which showed that bullying and job engagement were related (H1), CCM was related to less reports of bullying (H2), CCM was related to work engagement (H3) and that CCM was indirectly related to job engagement through bullying (H4), but only when CCM was weak (H5). That is, CCM moderated the relationship between bullying and work engagement in that this relationship only existed when CCM was low. The present study contributes to theory within this research field by showing that organizational measures may not only prevent bullying, but may also affect how employees react when subjected to bullying. Furthermore, the effect of climate in relation to bullying may be down to the narrow bandwidth facet of CCM. The study informs employers how they may act to prevent bullying while also reducing the potential negative outcomes of those cases of bullying that inevitably will show up from time to time.     

Chinese consumers’ preferences for food quality test/measurement indicators and cues of milk powder: A case of Zhengzhou,China

Many food regulations focus on test/measurement indicators, such as hazard analysis and critical control points (HACCP) and traceability, etc. Other than these indicators, the food industry uses various cues such as product origin as indicators of product quality. However, in an environment where consumers’ confidence in food safety is low due to frequent food safety scandals, little is known about the efficiency of these test/measurement indicators and cues. This paper used the primary data collected in Zhengzhou (China) to estimate consumers’ preferences for test/measurement indicators and a new cue of “own farm” for milk powder. Our results show that country of origin is the most important cue attribute, followed by price and own farm. The importance of test/measurement indicators such as organic, traceability, and HACCP certification is relatively low. Also, the individual parameter estimates show that consumers’ preferences for test/measurement indicators currently in the market are weak and fragile. Interestingly, price has an inverse-U-shaped relationship with consumer utility, implying that Chinese consumers may perceive low-price milk powder as low quality. The results of this study provide important insight for regulatory authorities and the food industry to develop more effective policies and programs to improve consumer preferences for milk powder.     

Reconciling Alternative Theories for the Safety of Owner–Operators

Motor carrier safety is an important concern of shippers, carriers, policy makers, consignees, insurance providers, and the motoring public. One aspect of carrier safety that has garnered substantial attention is whether carriers making greater use of owner–operators are more or less safe vis‐à‐vis carriers making greater use of employee drivers. Currently, conflicting theoretical predictions exist regarding the direction of this relationship. In this article, we offer a reconciliation of the alternative theoretical predictions by developing a coherent theory that merges sociological rational choice theory and theory regarding motor carrier safety. We subject our theory to empirical testing by fitting a series of seemingly unrelated regression models to a vector of safety measures tracked as part of the Federal Motor Carrier Safety Administration's Compliance, Safety, and Accountability program. Our results are consistent with our proposed theory of owner—operator safety and provide meaningful theoretical and managerial implications and directions for future research.     

Viewpoint: Future of food safety and nutrition - Seeking win-wins,coping with trade-offs

The possible implications of global trends such as climate change and resource scarcity on food security are high on the political agendas. While the food sufficiency aspect of food security takes centre-stage, the future of food safety and nutritional quality of diets often seems to be taken for granted. This paper builds on the results of a foresight study on EU food safety and nutrition towards 2050 to discuss potential future points of tension for food policy. Increasing food production while using fewer resources and reducing food waste while ensuring food safety are just two examples. Innovation at different levels in the food system will be needed to address future challenges. Fast technology uptake and the launch of new food-related products can put pressure on the ability to deliver timely risk assessments, the scope of which might also need to cover other legitimate factors. Future food policies need to be more sensitive to impacts on food safety and nutrition and health aspects. A holistic food systems approach must be taken to identify and discuss in advance possible tensions and trade-offs and to address them upfront in a systematic and transparent manner.
