Do myriad e-channels always create value for customers? A dynamic analysis of the perceived value of a digital information product during the usage phase

The academic literature generally asserts that omnichannel strategies create value throughout the customer journey based on the principle of synergy between channels. However, such strategies may appear complex to customers, notably when they face myriad e-channels that constitute all means of accessing the offer. Specifically, for digital information products, such as those of the press, digitalized content is now consumed through multiple e-channels. Our study aims to investigate the impact of e-channel combinations on the perceived value of a digital information product during the usage phase. We hypothesize that the similarity between the e-channels used by customers has a negative impact on the perceived value model. To test the research hypotheses, we conducted a longitudinal study of the readers of a digital version of an international newspaper. The results demonstrate that the similarity of e-channels impedes value creation. Our findings reintroduce a more ambivalent vision of the omnichannel strategy in a digital environment and provide insights into how managers should support customers by clarifying the usefulness of each e-channel proposed.

Consumer Protection Law in Ethiopia: The Normative Regime and the Way Forward

The 1960 Civil Code of Ethiopia and other laws have been providing a certain level of protection to consumers until the enactment of laws – in 2010 and 2014 – that expressly deal with consumer protection. This article examines consumer protection in Ethiopia with prime attention to the Trade Competition and Consumer Protection Proclamation No. 813/2013 (enacted in 2014). The social context which prompted the enactment of specific consumer laws in Ethiopia, sources that have influenced Ethiopia’s consumer law regime, rights of consumers, obligations of business persons, regulatory enforcement schemes and some features of consumer protection in digitalized services are highlighted. Moreover, the article briefly deals with the way forward regarding consumer enablement as a path to the effective implementation of consumer rights to choice, safety, information and redress. It is argued that the articulation of specific consumer laws can hardly be implemented unless consumers are adequately empowered to secure their rights and entitlements through effective redress which should include public interest litigation, class action and enhanced civil society engagement.

An ethnography of Electronic Shelf Labels: The resisted digitalization of prices in contemporary supermarkets

Contemporary retail markets have experienced and are experiencing an important digitalization shift in the form of computers and associated technologies. Among a large array of digital innovations, Electronic Shelf Labels (ESLs) deserve particular attention. ESLs, despite their long history and many benefits, have not become ubiquitous. The purpose of this paper is to account for this “resisted evolution” of digitalized prices. It draws theoretically upon science and technology studies, infrastructure studies, market studies, and previous literature on price representations in retailing. It draws empirically on a combination of ethnographic and historical methods. The paper shows that ESLs do not replace paper prices, but, rather, work together with them: on one hand, they compete to represent prices with their respective features, and on the other, they co-operate in order to reinforce the visibility and attractiveness of products and promotions.     

Information seeking by female apparel consumers in South Africa during the fashion decision‐making process

Fashion information is sought during the fashion decision‐making process and can be obtained from various sources such as magazines, fashion consultants, websites and store displays. Various levels and methods such as internal and external search for information are used to assist the consumer in making informed fashion decisions. The broad research aim of this study was to determine which methods, sources and economics of fashion information are sought and used by female educators in Vanderbijlpark (South Africa) during the fashion decision‐making process, and to which extent. A self‐administered, structured questionnaire was used to collect the data. Section A measured methods of information seeking, section B determined the economics of information search and section C investigated sources of fashion information. Demographic information was investigated in Section D. A random cluster sample of eight schools was chosen from the female educating staff of 22 schools. The biggest group of the educators (40.18%) was between the ages of 41 and 50, which according to a South African categorization represents baby boomers. Almost all (95.5%) had a higher education qualification obtained at a university and most (82.14%) were married. Regarding the methods of information seeking, the respondents depended on internal information seeking more than on external methods and were moderately involved in the process. Shopping in stores was regarded the most important source of fashion information. Cluster analysis revealed that four clusters of respondents could be distinguished, each with a specific disposition towards the methods and economics of search as well as sources used during the fashion decision‐making process.
