Brand effect on extended warranty valuation: Subjective value versus popularity

In five experiments, we explore the effect of brands on warranty valuation and the conditions under which two mechanisms – liking based and availability based – determine the effect. We explore the moderating role of focused deliberation, which accentuates the brand effect under availability mechanism but reduces the effect under subjective value-based mechanism. In Experiment 1, we consider brands that vary in terms of both subjective value and popularity. When a brand is better in both subjective value and popularity, it commands higher warranty WTP. Focused deliberation moderates this effect of brand on warranty valuation. In Experiment 2, we consider brands that vary only in terms of subjective values (but not popularity). While the warranty valuation of the two brands does not differ under no deliberation, deliberation decreases WTP for brands with higher subjective value. In Experiment 3, we consider brands that differ only in terms of popularity (and not subjective value). In this context, deliberation increases warranty WTP for the more popular brand. Experiments 2A and 3A use warranty choice as the dependent variable and conceptually replicate the effects obtained in experiments 2 and 3, respectively.     

关系型借贷视角下购房融资方式与家庭创业行为——基于2017年中国家庭金融调查的实证研究

本文利用2017年中国家庭金融调查数据深入考察购房融资方式对家庭创业行为的影响。研究结果显示,相较于民间借贷购房的家庭,按揭贷款购房的家庭参与创业活动的可能性更高,且更倾向于主动创业。进一步机制分析发现,相较于民间借贷购房,按揭贷款购房能够降低家庭的流动性约束,缓解家庭的资金压力,从而促进创业。同时,按揭贷款购房能使家庭获得充足的贷款额度与较长的贷款期限,进而有助于家庭创业。而且在偿还按揭贷款的过程中,家庭能与银行建立长期良好的信贷关系,从而有助于提高家庭获得正规信贷的可能性,促进家庭创业。为了积极推进创业创新的战略部署,应进一步健全银行信贷体系,发展和完善住房金融制度,从而有利于缓解小微企业融资难、融资贵的问题,释放和激发家庭创业活力。     

Prospects for food security in the 21st Century: with special emphasis on Africa

Food security for the world in 2025 is possible and probable if the right set of things are done, starting now. But the task will not be easy. It is both a technology and a political/economic challenge. The challenge for sub-Saharan Africa is even greater. While other regions improved per capita food availability over the last 30 years, Africa's availability declined. But food security is about more than supply. It is also about access which means income generating employment is critical. Meeting future requirements in Africa and the world will require sustainable intensification of complex production systems, appropriate national and international policies and continued investments in agricultural research. Without these conditions and increased employment intensive growth, prospects for the future are less bright.     

大数据环境特征对IT外包项目绩效的影响

对知识密集型的IT外包行业来说,大数据环境成为接包企业潜在的知识来源。然而,大数据环境是否真的促进IT接包项目绩效？如何从中获益？现有文献对这些问题缺乏研究。基于资源编排理论,探讨了大数据易得性和冗杂性对IT接包项目绩效的直接影响,检验了功能组合和专项突破两种软件开发策略的调节作用,提出6条假设,采用195个IT外包项目数据进行检验。研究发现,大数据易得性显著提高接包项目绩效,而大数据冗杂性显著降低项目绩效;功能组合策略增强而专项突破策略削弱了大数据易得性对项目绩效的促进作用;两种开发策略对大数据冗杂性与项目绩效关系的调节作用不显著。     

基于节点企业优选的生态工业园构建研究

本文首先介绍了生态工业园的概念。在此基础上,对当今国内外生态工业园构建情况进行论述,得出生态工业园构建的两条关键因素是共生链的建立与废弃物的处理。本文围绕两条关键因素,对生态工业园构建进行分析。根据生态工业园所需要完成的功能,列出达到共生链所需要六个条件,应用向量内积公式的方法,按照六个条件对企业进行两两内积运算,找出传统工业园中存在的或者潜在的共生链。传统工业园内的企业经共生链相连,形成传统工业园网络,可通过网络有向图表示。对传统工业园中的各个节点企业进行中心性分析,得出各节点企业的共生链占有率。分析和论述传统工业园中的企业废弃物的可用性以及污染度,研究废弃物的处理方法。将生态工业园构建两条关键因素分析向结合,对传统工业园内的节点企业进行优选,并给出处理对策,进而完成生态工业园的初步构建。     

The effect of customer service on retailers’ shareholder wealth: The role of availability and reputation cues

Retailer customer service has been shown to lead to increases in consumer attraction and retention, but what is less apparent is whether shareholders are fully rewarded for retailers’ customer service efforts. Results from an event study on 48 retailer announcements of customer service strategies indicate that customer service increases retailer market values by 1.09 percent on average. The magnitude of this abnormal return suggests that customer service is one of the more effective ways for firms to create shareholder wealth. Further, analysis of the abnormal returns suggests that the shareholder value created by the retailer's customer service is affected by the heuristics and cues used to judge the likelihood of service delivery. Consistent with the availability heuristic, we find that services that are difficult to bring to mind and non-vivid services create significantly less shareholder value. Results further show that the retailer's reputation can also significantly inhibit the customer service's shareholder wealth creation.     

新型货币政策担保品框架的绿色效应

本文以2018年6月我国央行开始接受绿色信贷资产作为MLF合格担保品这一事件为准自然实验,运用双重差分模型分析我国新型货币政策的担保品扩容对绿色信贷企业融资的影响。研究结果表明:第一,将绿色信贷资产纳入央行合格担保品范围增加了绿色信贷企业的信贷可得性,并降低了绿色信贷企业的信贷成本;第二,企业的异质性分析表明,民营绿色信贷企业在融资可得性方面对政策反应更显著,国有绿色信贷企业在融资成本方面对政策反应更显著;第三,分行业的扩展性检验表明,央行合格担保品扩容政策对于环保行业的绿色信贷企业主要通过提高融资可得性发挥作用,而对于重污染行业的绿色信贷企业则主要作用于其信贷融资成本。基于以上实证结果,本文认为央行担保品扩容具有绿色效应,可综合运用央行担保品框架和借贷便利类货币政策工具,加强我国新型货币政策的定向调控功能。     

贫困农户信贷可获得性影响因素的实证研究

本文运用判别抽样法,定点选取了16个省（市）国定贫困县中的1503户暂时性贫 困农户为对象,对其经济特征、信贷需求及贷款可获得性进行了调查分析,在此基础上,运用 Probit模型对其贷款可获得性影响因素进行了实证检验。调查发现：大多数暂时性贫困农户均 有信贷需求,且以中短期和小额为主,用途以消费为主,生产次之,信贷可获得性整体偏低, 且正规信贷获取难度大于非正规信贷。实证结果显示：户主受教育程度、家庭收入、社会关系 对贫困农户正规信贷和整体信贷可获得性均有正向影响;家庭社会关系及区域影响力对非正 规信贷可获性有显著正向影响,金融机构物理距离对贫困农户信贷可获得性产生了一定的排斥 效应。可见,户主文化程度、家庭收入、社会关系、金融网点已成为我国贫困农户信贷可获得 性的现实制约因素。
