Longitudinal analysis versus cross-sectional analysis in assessing the factors influencing shoppers’ impulse purchase behavior – Do the store ambience and salesperson interactions really matter?

Numerous studies in the marketing literature focused on consumer behavior in general, but relatively few studies have examined Impulse purchase behavior (IPB). Although few studies examined IPB, the vast majority of the studies were conducted using the cross-sectional design. These studies suffer from certain limitations like random measurement error, common method bias, causality & validity-related issues that are inherently associated with the cross-sectional design. Despite these limitations, very few studies have examined the IPB using the longitudinal design. Multilevel structural equation modeling (ML-SEM) is conducted in the study to analyze the longitudinal data for examining the changes in the causal effects of the factors influencing the shoppers' IPB over a period of time. Additionally, structural equation modeling (SEM) is conducted to examine changes in the causal effects of the factors influencing IPB at each time point of data collection. Drawing upon the stern's model and stimulus-organism-response model, the study examines the causal effects of the factors influencing the IPB. The results of ML-SEM indicate significant fluctuations in the factors influencing IPB over time. Similarly, the results of SEM indicates that few factors (like store ambience and salesperson interactions) have shown a significant influence on IPB in the initial time points (i.e., during the initial store visits of shoppers), but became insignificant over a period of time in their subsequent store visits. The findings suggest that the store crowd, secondary customers influence, and in-store promotions show a significant influence on the IPB, compared to the store ambience and salesperson interactions.     

An empirical examination of the effects of design elements of email newsletters on consumers’ email responses and their purchase

In this research, we empirically explore the effects of various design elements of email newsletters on consumers' email responses and their purchases. We capture the consumers' email responses using three metrics, namely email open, email click, and email reopen. We operationalize consumers' purchases as their spending on product items that are featured in email newsletters. Using a novel email marketing database, first, we model the influence of design elements of email newsletter on consumers' email responses at the individual consumer level. The email design elements constitute several email attributes, situational factors, and integrated marketing communication. Second, we quantify the effects of these three email responses, open, click, and reopen, on consumers' purchases. Our empirical results suggest a significant influence of email attributes, situational factors, and marketing communications on consumers' email responses. Furthermore, among open, click, and reopen, we find clicks tend to have the highest impact on consumers’ purchase, followed by email reopening and opening. However, email newsletters with higher opening probability are more effective in influencing purchases than those email newsletters with higher reopening probability. Furthermore, consumers who indulge in all three email responses, namely opening, clicking, and reopening, tend to purchase the most. Results from our study offer several critical insights for email marketing strategy helping managers improving the effectiveness of email campaigns by careful consideration for the design elements of email newsletters.     

电商不同类型促销对购买行为的长期影响——以亚马逊电子书为例

促销的长期影响在学术界一直备受争议,并且传统研究更多地关注实体企业的促销效果,而对电商平台的促销活动研究较少。为了厘清电商平台的不同促销方式对消费者购买行为的长期影响,本文基于亚马逊电子书的销售数据,建立固定效应模型考察了降价和优惠券两种价格促销的长期影响。结果表明,降价促销会导致消费者未来购买数量减少、购买金额增加、购买时间间隔缩短;优惠券促销则会使得消费者未来购买数量增加、购买金额减少、购买时间间隔不变。在此基础上,本文进一步分析了消费者购买经验的调节作用。本文不仅丰富了已有促销长期影响的研究成果,而且对电商如何制定促销策略以优化促销长期效果提供了科学可行的建议,具有重要的理论意义和实践价值。     

社会互动对规模养殖户环保饲料支付意愿的影响研究*——基于改进的目标导向理论模型分析框架

［目的］通过引入社会互动变量改进目标导向行为理论框架，探讨生猪规模养殖户对环保饲料的支付意愿及其影响因素，为完善畜禽养殖污染防治政策提供参考借鉴。［方法］以湖北省生猪规模养殖户为研究对象，应用Heckman两阶段模型，研究规模养殖户对环保饲料的支付意愿。［结果］大多数规模养殖户（8134%）愿意采用环保饲料，且平均意愿支付水平为每头生猪饲料成本的669%（4680元/头）。社会互动中的干群互动、同行互动均能显著提升规模养殖户对环保饲料的支付意愿，但同时同行互动不利于其意愿支付水平的提升。进一步的异质性分析表明，在环保饲料支付意愿决策上，社会互动较少的规模养殖户更容易受到制度规范的约束，而社会互动较多的规模养殖户则更易受到感知养殖热情的影响。［结论］政府部门应加大生态环保宣传力度，并借助多种方式推动规模养殖户进行社会互动； 同时可依据社会互动程度的不同，分别制定相应措施以促进规模养殖户对环保饲料支付意愿的提升。     

乡村振兴战略下要素国际流动的环境效果

乡村振兴战略和环境保护是当前经济工作中的重点。伴随经济全球化和“一带一路”战略的不断深入,生产要素国际流动日趋频繁。乡村振兴是国家重要发展战略,其重要抓手是实现农业现代化。因此,在小农户与现代农业共存的经济背景下,分析要素国际流动的环境效果,并根据现代农业发展的不同特征,对乡村振兴战略实施初始阶段和全面实施阶段分别进行分析后发现:在战略实施初始阶段,劳动流入加剧污染,反之改善环境;在战略全面实施阶段,资本流入改善环境,反之恶化环境。     

土地复垦监管行为规范的主体性合作治理形式选择

研究目的:根据相关主体性意愿的指引,阐明合作治理范式在土地复垦监管行为领域展开具体运用的现实性,及其可能的规范设定方向,进而尝试在相应行为规范维度来检视行政行为法理论的发展任务命题。研究方法:文献分析法。研究结果:土地复垦监管行为的形式选择往往与相应的合作治理主体性意愿有关,该意愿主要表征为利益导向、工具载体以及协同组织选择意愿。应厘清该类选择意愿指引于土地复垦监管行为规范所分别呈现的形式选择:逐利心态与信任习惯选择、科学事实工具与行政规制工具选择、内部协同组织与外部协同组织选择。研究结论:土地复垦监管行为在行为观念和当事人方面与合作治理的主体性意愿在一定程度上是相互耦合的,有必要构建一种合作行政模式下的治理型土地复垦监管行为规范。     

UGC信息类型及发布者头像对其他用户购买意愿的影响 ——基于社会化电商小红书社区的研究

社会化电商社区包含着丰富的用户生成内容,通过用户生成内容的生成、分享和传播,影响用户的购买意愿。从小红书社区“带货”现象出发,以心理距离理论为视角,探究具有不同信息类型的用户生成内容对其他用户购买意愿的影响,并且研究拥有肖像类头像的发布者特征的调节作用。通过实验研究发现,在社会化电子商务社区中,体验型用户生成内容对其他用户购买意愿具有正向的影响,且用户感知心理距离产生中介作用,对于以肖像形象作为头像的发布者而言,这种影响更为显著。     

The Impact of Public Expenditure and International Trade on Agricultural Productivity in China

The “industry nurturing agriculture” reforms and World Trade Organization accession led to dramatic growth in public expenditure and international trade in China’s agricultural sector. This article aims to estimate the effects of public expenditure and trade on agricultural productivity in China for 2004–2015. A semi-parametric production function with shape constraints is introduced to derive more accurate productivity before the productivity determinants are analyzed with an emphasis on public expenditure and trade. The empirical result shows that public expenditure and exports can effectively improve agricultural productivity, while imports have no significant effects. Policy implications are discussed in the context of supply-side reforms.     

What lies beneath: Climate change,land expropriation,and zaï agroecological innovations by smallholder farmers in Northern Ghana

Large-scale land acquisitions (LSLAs) are increasing in Ghana amid a weak legal and regulatory framework. This paper explores the impacts of this phenomenon on farmer innovations under recurrent environmental changes. Using a case study of zaï, an indigenous innovative farming practice, the paper makes two interrelated arguments. Firstly, it shows that the pervasive enclosures coerced by the Ghanaian state undermine how indigenous knowledge could be proactively deployed for climate risk management. Secondly, LSLAs produce a social barrier to climate change adaptation, as they lead to heightened uncertainty and apprehension among farmers, which affects decisions on climate risk management. More specifically, land expropriation is an example of how adaptation could be hindered by governance, institutions, and policy at the extra-local scale, including not only existing land use laws, but also the constitutional guarantee of private property. The evidence supporting these arguments come from survey data on 619 plots, 70 in-depth interviews, village-level transect walks, and participant observations. Overall, the paper contributes to emerging debates at the interface of land use policy, climate justice, and sustainable adaptation. Theoretically, it also contributes to understanding State-society relations, as well as the political economy of eminent domain, often justified through discourses of “public benefits.”
