Designing a reverse logistics network for optimal collection, recovery and quality-based product-mix planning

This study proposes an integrated, reverse logistics supply chain planning process with modular product design that produces and markets products at different quality levels. A mixed integer programming (MIP) model formulates the overall planning process required to maximize profit by considering the collection of returned products, the recovery of modules and the proportion of the product mix at different quality levels. This paper proposes the collection of returnables (end-of life, defective, product under warranty) through retail outlets combined with the recovery of modules from the collected products using a network of recovery service providers. The proposed modular product design approach would create a design criterion that provides an improved recovery process at a lower cost. This study uses a total supply chain view that considers the production, transportation and distribution of products to customers, while a numerical problem illustrates the applicability of the models.     

How value and trust influence loyalty in wireless telecommunications industry

Despite making significant investments in enhancing the customer service experience, long-term customer loyalty remains an elusive dream for many service providers. Particularly in the telecommunications industry, switching providers even from within continuous contract relationships is easy and companies struggle to retain their customers. Trust and value are considered cornerstones of long-term relationships, so it is perhaps surprising that previous research on how relationship age and usage level actually affect value, trust and loyalty is inconclusive. The current research is set in the telecommunications services field and draws on a large-scale survey undertaken in Finland. The findings support the contention that perceived value relates positively to loyalty, and that trust mediates that relationship. Surprisingly, in the telecommunications industry, increasing relationship age and usage level strengthen neither value and loyalty nor the links between trust and loyalty. The results may be explained by the unique characteristics of the highly competitive mobile telecommunications sector, and confirm the view that loyalty does not pay without strategies that value long-term customers and thereby build trust with new customers.     

Consumers as time travellers: the moderating effects of risk perception and construal level on consumers’ responses to temporal framing

Abstract

This study investigated the conditions under which temporal framing is more effective in explaining consumers’ responses to ads. Two experiments were conducted with a 2 (temporal framing: near-future vs. distant-future benefits) × 2 (perceived risk: high vs. low) × 2 (construal level: high vs. low) between-subjects factorial design. In Experiment 1, the two-way interaction effect of temporal framing and perceived risk on ad attitudes and purchase intention was found, such that the near-future benefit frame generated more favourable responses to the ad under the high-risk condition. Incorporating construal level theory, the three-way interaction effect was found, with the temporal framing?×?perceived risk interaction appearing more pronounced for low construal consumers only. Experiment 1 also discovered that information diagnosticity mediated the interaction effect of temporal framing and perceived risk on ad attitudes and purchase intention and this mediating process appeared stronger for low construal consumers. Experiment 2 replicated the two-way and three-way interaction effects on purchase intention, providing evidence of the validity of the findings. Theoretical and managerial implications were discussed for researchers and practitioners.     

A mutuality perspective of psychological contracts regarding career development and job security

Psychological contracts are more likely to be fulfilled when the parties to the contract develop mutuality (agreement) concerning the expectations and obligations of both parties. This study explores the impact of psychological contract mutuality about career development responsibility and job security on the in-role and organizational citizenship behavior (OCB) performance of employees. These relationships are also tested to see if they vary by the managerial vs. non-managerial job level of the employee.

地区幸福感能提高企业的投资水平吗？——基于我国上市公司的经验证据

幸福感是一种综合性社会资本,会对经济主体的决策和行为产生积极影响。采用我国A股上市公司数据的实证分析表明：地区幸福感对企业投资具有显著的促进作用,地区幸福感水平越高则该地区企业的投资水平越高;与民营企业相比,地区幸福感对国有企业投资的促进作用更明显;地区幸福感对民营企业投资的正向影响随市场化程度的提高而减弱,但这一负向调节作用在国有企业中并不明显。因此,各级政府应该积极提高居民的幸福感水平,进而有效促进地区经济高质量发展。     

中国居民家庭收入流动性结构与影响因素研究——加入心理因素的城乡比较分析

收入流动将对收入分配格局产生重要影响,良好的收入流动性结构有利于缩小收入差距、优化收入格局。基于2010—2016年中国家庭追踪调查数据的分析表明,在2010—2012年、2012—2014年和2014—2016年三个时间段,整体样本、农村样本和城市样本家庭收入流动的向上/向下比率均大于1,表明当前中国居民家庭收入流动性结构合理,有利于收入分配格局优化;虽然低收入层级向上流动的几率较大,但高收入层级（尤其是城市地区）固化的现象也较为显著;长期来看,居民受教育水平和幸福感的提高有助于防范家庭收入层级向下流动。因此,应进一步提高教育质量,并切实增强人民群众的幸福感。

市场不确定性下的电影保底发行模式抉择机制探究

随着近年来不断增大的社交网络影响,电影市场中影片发行方式开始显现出其规避风险的特性.基于市场不确定性所带来的收益风险,在保底发行模式下考虑了一个电影制片方及一个影片发行方的多阶段博弈模型.研究发现,相较于传统的分账发行模式而言,保底发行模式牺牲了制片方的部分期望收益,但能够有效降低其市场风险.部分市场风险通过保底发行模式被转嫁给发行方,但同时,该模式为发行方带来更高的期望收益.此外,市场不确定性的提高会打击制片方的运营信心并使其降低前期努力投入,但是会促使发行方增加其努力投入以提高影片的最终票房.
