New Cultures,New Strategies,New Formats and New Relationships in European Retailing

Abstract

During the last fifteen years there has been a substantial restructuring of retailing in Europe. The implications of this reach beyond Europe. The restructuring involves not only competitive relationships amongst retailers but also involves new forms of relationships with suppliers. A new perspective of the role of retailing is emerging that places retailing in a global framework of international store operations, international sourcing of products, international flows of management and managerial know-how, and international awareness by consumers of the retailers who are becoming international brands. The aim of this paper is to place the restructuring in context, to consider the nature of it and to explore how the new global framework will begin to have effects for distribution industries in Asia.     

Technologies of Translocality: Vegetables,Meat and Dresses in Arab Muslim Detroit

The diversification of US suburbs in terms of race, ethnicity and immigration has created invaluable opportunities for scholars to study technologies of translocality‐in‐the‐making. Translocal landscapes are described as spaces of ‘here' studded with ‘parts of elsewhere' (Allen and Cochrane, 2007 )—but which pieces of the landscape count as meaningfully ‘of elsewhere', how do those parts get there, and what range of meanings can they signify? This article is based on qualitative, in‐depth interviews and explores these questions in the context of an Arab Muslim ethnic enclave and retail district in an inner‐ring suburb of Detroit. The findings indicate that ‘parts of elsewhere' are more internally pluralized, multifunctional, multidirectional and aesthetically diverse than commonly recognized. The implications of these findings challenge scholars to develop more robust frameworks to explain how translocal geographies are produced, why they matter, and how they can be recognized.

城镇居民收入水平对零售业与批发业影响的实证研究——基于协整和向量自回归模型

文章选取1995年-2008年我国城镇居民家庭人均可支配收入和零售业销售总额、批发业销售总额的时间序列数据,通过基于VAR模型的协整分析、脉冲响应分析和方差分解的有机结合进行研究,发现上述序列间存在长期均衡。对标准化协整方程和误差校正模型的分析表明,我国城镇居民收入水平和零售业销售总额、批发业销售总额之间形成了长期的、稳定的关系,且城镇居民收入水平是零售业销售总额、批发业销售总额的格兰杰原因。脉冲响应分析和方差分解均显示,城镇居民收入水平在过去十四年内对零售业、批发业产生了持续性的影响。     

How much do plant guarantees reduce perceived risk?

Abstract

Consumers do perceive risk in purchase decisions and seek to reduce both uncertainty and probability of loss. Risk also varies across persons and purchasing situations. Retailers promote product guarantees as risk reducers, but the quantitative evidence is lacking. They offer guarantees to help resolve outcomes from post-purchase problems mainly, product performance. We used an online survey to investigate the role of risk mitigation by money-back guarantees (MBGs) on a live product: plants. We obtained online responses from 504?US residents?≥?age 18 years who had made at least one live plant purchase in the six months prior to the study. As MBG length increased, perceived risk (PR) decreased. PR was higher for men than for women and declined as income increased. Subjects with a higher level of product involvement, expertise, delight, repurchase intentions, and regret had a higher level of PR. We conducted separate Chow tests for annual and perennial plants by price and MBG length and found several break points. As price increased from $5 to $10, a 30-d MBG reduced PR for annual plants while the reduction in PR was incrementally decreased for all guarantee lengths when annuals were priced over $20. With perennial plants, the MBG had an increasingly larger effect on reducing PR for each $10 increase in price. Overall, for each day increase in MBG length, we observed a 0.0337 decrease in PR, which meant that a 90-d MBG on a plant would reduce PR by 3%. This quantitative evidence of reduction in PR should encourage the use and communication of MBGs which have the potential to improve purchases, customer retention, and profitability.
