The purpose of this paper is to investigate how the service constellation perspective affects innovation strategies and potentially contributes to the innovation literature, proposing a research agenda.

By analyzing the notion of a service constellation, the authors provide an overview of major implications for service innovation research and practice.

Firms and service innovation researchers need to focus on the perceived consumer value of the constellation rather than on individual services. The authors illustrate how service innovation from the constellation perspective requires coordination and synchronization between projects and different approaches to portfolio management and screening.

Adoption of the service constellation perspective creates new opportunities.

The purpose of this paper is to provide insight into how consumers cope with confusion caused by overload in information and/or choice. The paper investigates whether consumers who face different degrees of confusion use different coping strategies depending upon their decision‐making styles.

The Dutch mobile phone market is a typical example of a turbulent market, overloaded with information and/or choice, which creates consumer confusion. A survey was conducted among 203 mobile phone users, using valid and reliable multi‐item scales to measure consumer confusion, decision‐making styles and coping strategies. Cluster analysis and Mancova were used to provide insight into the results.

The paper finds that consumers of mobile phones can be characterized by combinations of decision‐making styles and find three clusters based on decision‐making styles: “price conscious and cautious” consumers, “brand‐loyal and quality‐driven” consumers, and “functionalist” consumers. Results show significant main effects of the degree of confusion and the decision‐making styles on the use of coping strategies as well as a significant interaction effect of these two. Higher levels of consumer confusion lead to an increased use of seven coping strategies: downsizing the consideration set; keeping status quo; reduced information search; search deferral; buying what others have bought; disengagement from decision; and decision delegation. “Price conscious and cautious” consumers engage less in downsizing the consideration set than the two other clusters, and are less inclined to keep the status quo as compared to “functionalist” consumers.

Because of the intangible and heterogeneous nature of services, knowledge about coping with confusion due to an overload in information and choice is especially important for service providers in their efforts to build and sustain strong relationships with consumers. Practical implications in terms of different approaches on how to cope with confused consumers are provided.

This paper seeks to improve the understanding of implementation processes that achieve corporate sustainability by providing explanatory knowledge about the role of change agents from a sensemaking perspective. The paper also aims to focus on the sustainability efforts of change agents in a multinational carpet tile manufacturer.

The theoretical perspective of the paper is based on the concepts of sensemaking and emergent change. The paper examines sustainability sensemaking in the Dutch subsidiary of the US‐based carpet tile manufacturer Interface over a period of ten years (2000‐2010).

The findings show that embedding sustainability by change agents is typically an emergent change process that consists of small steps and is not predictable.

This paper focuses on the emergent, unpredictable aspects of change. More research is needed on processes of adapting the general concept of sustainability to local organisational contexts.

The paper examines sustainability sensemaking by change agents in one organisation.

Reality television is a dynamic, profit-making platform that occupies prime-time slots on the television almost all over the world. Despite its immense popularity and influence, it has received little attention in the extant literature and almost none in terms of its impact on celebrity repositioning. This study aims at examining the relationship between the film stars as brands and the impact of the platform of reality television in repositioning these celebrities in the Indian context.

Through extensive literature review and qualitative interviews, the paper expounds that reality television provides an opportunity to celebrities to successfully reposition themselves at crucial junctures in their career. The framework to study this repositioning has been adopted from the work of Chris Simms and Paul Trott (2007) who created it to study the brand repositioning of various consumer goods.

The literature establishes celebrities as brands. This study provides evidence that brand repositioning through reality television is possible for these celebrity brands. The symbolic and functional repositioning of these celebrities is presented through thematic content analysis.

The study provides a useful framework to understand celebrity brand repositioning through reality TV. It can also be replicated to understand the repositioning of a wide variety of celebrities other than film-stars such as sportspersons, social media influencers and politicians.

The paper contributes to the need of expanding the corpus of Indian reality television and explains how Indian celebrities reposition themselves through reality television.

The purpose of this paper is to examine whether there exist significant benefits from diversification into frontier markets for an Australian investor in comparison to a US investor.

The study uses the computationally efficient ADCC GARCH model to estimate time-varying correlations of returns. The authors also compare the results to DCC GARCH correlations in order to test whether the results are model-specific. Optimal portfolios with several restrictions were constructed and the results from Australian and US investors were compared. The study also uses a holding out period that is rebalanced at the end of each quarter using new portfolio weights.

The study finds that there are significant benefits for the Australian investor from diversifying into frontier markets. However, the benefits to the US investor are much higher than that of an Australian investor. The results from the holding out period also present significantly higher benefits to the US investor compared to the Australian investor.

This study examines the diversification benefits to the Australian investor from frontier markets and compares the benefits of the Australian and the US investors. The results emphasise the potential benefits from including frontier markets in the portfolio. The paper also presents a holding out period analysis.

The latest information from the magazine chemist is extremely valuable. He has dealt with milk‐adulteration and how it is done. His advice, if followed, might, however, speedily bring the manipulating dealer before a magistrate, since the learned writer's recipe is to take a milk having a specific gravity of 1030, and skim it until the gravity is raised to 1036; then add 20 per cent. of water, so that the gravity may be reduced to 1030, and the thing is done. The advice to serve as “fresh from the cow,” preferably in a well‐battered milk‐measure, might perhaps have been added to this analytical gem.

There are very few individuals who have studied the question of weights and measures who do not most strongly favour the decimal system. The disadvantages of the weights and measures at present in use in the United Kingdom are indeed manifold. At the very commencement of life the schoolboy is expected to commit to memory the conglomerate mass of facts and figures which he usually refers to as “Tables,” and in this way the greater part of twelve months is absorbed. And when he has so learned them, what is the result? Immediately he leaves school he forgets the whole of them, unless he happens to enter a business‐house in which some of them are still in use; and it ought to be plain that the case would be very different were all our weights and measures divided or multiplied decimally. Instead of wasting twelve months, the pupil would almost be taught to understand the decimal system in two or three lessons, and so simple is the explanation that he would never be likely to forget it. There is perhaps no more interesting, ingenious and useful example of the decimal system than that in use in France. There the standard of length is the metre, the standard of capacity the cubic decimetre or the litre, while one cubic centimetre of distilled water weighs exactly one gramme, the standard of weight. Thus the measures of length, capacity and weight are most closely and usefully related. In the present English system there is absolutely no relationship between these weights and measures. Frequently a weight or measure bearing the same name has a different value for different bodies. Take, for instance, the stone; for dead meat its value is 8 pounds, for live meat 14 pounds; and other instances will occur to anyone who happens to remember his “Tables.” How much simpler for the business man to reckon in multiples of ten for everything than in the present confusing jumble. Mental arithmetic in matters of buying and selling would become much easier, undoubtedly more accurate, and the possibility of petty fraud be far more remote, because even the most dense could rapidly calculate by using the decimal system.

The purpose of this paper is to explore the implications of the selfie for marketing management in the era of celebrity. The purpose is to show that the facilitation of the creative performance of consumer identity is a key element of the marketing management task for the media convergence era.

The paper uses the selfie, the picture of oneself taken by oneself, as a metaphor to develop a conceptual exploration of the nature of marketing in the light of the dominance of celebrity and entertainment in contemporary media and entertainment.

The paper suggests that marketing management in the era of convergence should facilitate consumers’ identity projects through participatory and engaging social media initiatives. Marketers must furnish and facilitate not only the props for consumers mediated identity performances, but also the scripts, sets and scenes, plot devices, cinematographic and other visual techniques, costumes, looks, movements, characterizations and narratives.

This is a conceptual paper that sketches out the beginning of a re-framed, communication-focussed vision of marketing management in the era of media convergence.

Marketing managers can benefit from thinking about consumer marketing as the stage management of consumer visual, physical, virtual, sensory and psychic environments that enable consumers to actively participate in celebrity culture.

This paper suggests ways in which marketing practice can emerge from its pre-digital frame to embrace the new digital cultures of consumption.

This paper aims to explore the nature of the celebrity chef phenomenon and its impact on the contemporary hospitality industry, to both enrich current knowledge on the topic, as well as inform future research endeavors.

The study was based on a narrative literature review of secondary data sources, namely, academic literature and industry-related articles, and video data collected from popular video-hosting websites.

Despite the vast popularity of celebrity chefs, the phenomenon remains underexplored, with limited coverage given to it by hospitality-related literature. Prior investigations primarily focused on celebrity chefs’ commercial influence and power of advocacy, with little reference to their impact on the next generation of culinary professionals and on the sustainability of the profession.

This commentary has numerous theoretical and practical implications for industry stakeholders who wish to explore this phenomenon beyond the limited confinements of its commercial impact. In particular, the study explores the nature of the phenomenon, where television, social media and the celebrity status of chefs influence both the values and norms surrounding the profession, and individuals’ vocational choices. That said, findings suggest that additional research is required on this topic.

The exploration of celebrity chefs as a topic has so far been limited and has leaned toward one dimension in hospitality literature, despite its interesting scope. This critical overview provides conceptual clarity on issues such as the phenomenon’s commercial and vocational impact and highlights areas of concern and opportunity. Moreover, the study sets a clear pathway for further research.

Considering the continuous rise in the public debt stock of developing countries (particularly Ghana) with the unstable economic growth rate for the past decades and the recent borrowing because of the impact of COVID 19, this paper aims to examine the causal relationships between public debt and economic growth over time.

The paper uses a dynamic multivariate autoregressive-distributed lag (ARDL)-based Granger-causality model to test the causal relationships between public debt and economic growth [gross domestic product (GDP)]. Annual time-series data that spanned 1978–2018 were sourced from the World Bank Development Indicator database and the IMF fiscal Affairs Department Database and WEO.

The results reveal that public debt has no causal relationship with GDP in the short-run but there is unidirectional Granger causality running from public debt to GDP in the long run. Again, investment spending has a negative bi-directional causal relationship with GDP in the short-run but they have a positive bi-directional causal relationship in the long run. Conversely, no short-run causal relationship exists between government consumption expenditure and GDP but long-run Granger causality runs from government consumption expenditure to GDP. Finally, public debt has a positive impact on the inflation rate in the short run.

The findings imply that government(s) must ensure high fiscal discipline to serve as a precursor for the effective and efficient use of recent borrowing, that is, the loans should be used for highly prioritized projects (preferably investment spending) that are well evaluated and self-sustained to add positively to the GDP.

This paper provides contemporary findings to augment extant literature on public debt and economic growth by using variables and empirical models, which prior studies could not sufficiently cover in a developing country perspective and affirms that public debt contributes to GDP only in the long run.
