Abstract

Purpose

In futures markets, margin trading not only relaxes leverage constraints but also entails the risk of margin calls. Therefore, existing studies provide inconsistent evidence on low-risk anomalies, raising challenges in understanding leverage constraints in futures markets. This study aims to address this gap by focusing on margin call risk. Through bootstrap simulations with historical datasets, we find that margin call risk increases with longer investment horizons regardless of the initial margin, maintenance margin or individual futures volatilities. We also find that investors generally prefer higher leverage but adjust it in response to margin call risks across all futures sectors, leading them to opt for lower leverage for longer holding periods. Thus, while low-risk anomalies demonstrate statistical significance over longer investment horizons, their significance decreases for shorter investment horizons, such as less than six months. Our findings suggest that investors with sufficiently short holding periods are less likely to face leverage constraints in futures markets, especially the commodity, currency and bond futures markets.

Abstract

Man has been seeking an ideal existence for a very long time. In this existence, justice, love, and peace are no longer words, but actual experiences. How ever, with the American preemptive invasion and occupation of Afghanistan and Iraq and the subsequent prisoner abuse, such an existence seems to be farther and farther away from reality. The purpose of this work is to stop this dangerous trend by promoting justice, love, and peace through a change of the paradigm that is inconsistent with justice, love, and peace. The strong paradigm that created the strong nation like the U.S. and the strong man like George W. Bush have been the culprit, rather than the contributor, of the above three universal ideals. Thus, rather than justice, love, and peace, the strong paradigm resulted in in justice, hatred, and violence. In order to remove these three and related evils, what the world needs in the beginning of the third millenium is the weak paradigm. Through the acceptance of the latter paradigm, the golden mean or middle paradigm can be formulated, which is a synergy of the weak and the strong paradigm. In order to understand properly the meaning of these paradigms, however, some digression appears necessary.

Abstract

Purpose

Despite increasing focus among scholars and practitioners on the design of product-service systems (PSS), there exists no compilation of current knowledge on the role played by small and medium-sized enterprises (SMEs) in designing such systems. Thus, this paper sets out to identify and organise the existing research and suggest questions for future research.

Design/methodology/approach

A systematic literature review was performed to identify and provide in-depth details on key themes in the literature addressing the design of PSS in SMEs.

Findings

This paper identifies five themes in the literature on the design of PSS in SMEs: motives, challenges, SME characteristics, methods and digitalisation. The themes are interrelated, and SME characteristics seem to be at the core as they are related to all the other themes. Gaps in the current knowledge are identified, and questions for future research are suggested.

Originality/value

The suggestions for future research provide a starting point for expanding the research on PSS design and devising practical support for SMEs.

Abstract

BY the time these words appear the majority of those who attend Library Association Conferences will have made tentative arrangements for their visit to Margate in June. Already, we understand, adhesions are coming in as many in number as for any September conference, and, if this is so, the fact will reassure those who have doubts of the wisdom of the change from September to June. We give on other pages some outline of the programme and in Letters on Our Affairs are presented with a Study of the subjects of the papers. Here we can concentrate upon one or two important points.

Abstract

Purpose

There are many entrepreneurial communities in the Asian subcontinent, which are known for their economic resilience and religious orientation but have received limited attention in extant literature. These communities include Memon, Delhiwala, Chinioti, Ismaili and Bohri, which have been persistent in keeping their members economically stable, as many centuries, while also retaining their religio-sociocultural identity. This paper aims to add to the body of literature by documenting the possible factors, which contribute toward advancing socio-economic justice for the members of respective communities.

Design/methodology/approach

This study uses Eisenhardth research strategy within a social constructivist paradigm to process data from in-depth interviews, memos and documentary sources to explore the internal dynamics of three most prominent of these communities (Memon, Delhiwala and Chinioti) in Pakistan.

Findings

The findings reveal that the secret to their resilience is, perhaps, rooted in their religio-sociocultural communal norms, which may not just ensure effective wealth redistribution among the deserving segments of the society but may also enable its deserving members to achieve self-reliance through community-supported–entrepreneurial–activity. This study proposes that a culture of community-based–family–entrepreneurship coupled with the spirit of cooperation, sacrifice and reciprocity may eliminate the possibility of socioeconomic injustice.

Social implications

The religious entrepreneurial communities may be seen as an alternate to free-market or state-driven methods to impart socioeconomic justice where needed. The voluntary inclination of entrepreneurs in such communities to facilitate those in need may, perhaps, reduce or even eliminate the need to involve state intervention to redistribute wealth through taxation, which may also eliminate the cost of the state bureaucracy, which is used for the collection and redistribution of taxes.

Originality/value

The findings add to the body of literature which could help similar communities to improve their socioeconomic stability in a just manner for all its members. Policymakers can also take notice of the religio-sociocultural norms at the source of socioeconomic justice within the respective communities to formulate policies conducive to sustaining such norms where necessary.

Abstract

Purpose

The purpose of this study is to disclose ontology of DSI as a novel concept in servitization community, explore the research context and themes (i.e. technological and industrial sectors) where DSI emerges, unveil methodological complexities of the research on digital servitization and DSI and provide guidelines for future research avenues regarding DSI.

Design/methodology/approach

Bearing in mind the relative novelty of DSI as a concept in servitization literature, the authors adopted a systematic literature review approach to identify 111 peer-reviewed articles published in English language and available in business and management disciplines via scholar databases (Scopus). The analysis of literature discloses descriptive and thematic insights regarding digital servitization and DSI.

Findings

The study provides valuable insights from the descriptive and thematic analyses where classification of articles per publication year, citations, methodology/type of the paper, geographical location of data collection, as well as industrial sector and technological contexts are discussed. Moreover, the unique value of this study is observed through its specific focus on the characteristics of DSI-related literature.

Originality/value

The study is among the first of its kind to provide extensive descriptive and thematic insights on the available literature dealing with digital servitization and DSI, mapping out prior research across a wide spectrum of publication outlets and illustrating the chronological evolution of research on digital servitization and DSI.

Abstract

Purpose

Over recent years, public health threats, economic losses and crises of confidence resulting from adverse events along the global food chains have pressured food traceability systems to operate more efficiently. Based on that, this paper aims to expand the body of knowledge on the connection between Industry 4.0 technologies and food chain traceability and how they have been integrated.

Design/methodology/approach

Before conducting a systematic literature review (SLR), we consulted academic experts in traceability and Industry 4.0 technologies to define the leading 4.0 technologies adopted. We then developed protocols and criteria for article selection. Based on the developed codebook, we performed a content analysis, refining it through discussions with experienced researchers.

Findings

This paper identified seven Industry 4.0 technologies applied in conjunction with support and device systems. These combinations hold promise for generating value for food chain traceability systems. Value for the food supply chain originates from five sources: trust, process improvement, data processing, security, sustainability and regulation. Besides, three barriers to implementing such traceability technologies were identified: resources, lack of structure, stakeholders and values.

Research limitations/implications

While this study focused specifically on the food chain, the technology combinations, values, barriers and categories identified herein can inform analyses for other chains, e.g. the pharmaceutical chain. Moreover, due to the recent growth of this topic, some existing values and barriers may not have been fully explored and the technology combinations may vary slightly.

Practical implications

The results of this study provide food chain professionals with a comprehensive understanding of the values and corresponding barriers associated with employing Industry 4.0 traceability technologies. This knowledge can be leveraged to develop effective strategies and implement improvements in traceability, thereby benefiting society and addressing identified barriers.

Originality/value

This study expands the literature on using Industry 4.0 technologies for traceability in food chains, providing valuable directions to build safer, more efficient, transparent and potentially more sustainable food chains. Additionally, we provide promising avenues for future research.

Abstract

Purpose

Recently, increasing costs and competitive pressure have accelerated the search for different business models in both the production and service sectors. The rapid development of technology has increased the importance of digitalization, especially in developing new and different strategies. The digital service business model has also become a new business model that companies have recently preferred. In addition to its many advantages, it is a business model in which different barriers arise in practice. When we look at the literature, there are very few studies, especially on digital servitization. The purpose of this study is to integrate the concept of digital servitization with the Industry 4.0 perspective.

Design/methodology/approach

To achieve this aim, first, the authors identify various challenges and barriers in front of digital servitization based on the Industry 4.0 perspective. Later, they determine the relative importance of these barriers critical to the success of digital servitization. Lastly, one multi-criteria decision-making method, the fuzzy decision-making trial and evaluation laboratory method, is used to analyze the cause-and-effect relationship between each barrier based on the Industry 4.0 perspective

Findings

Based on the results, the most crucial cause-and-effect barriers are insufficient infrastructure/lack of IT infrastructure and high implementation, respectively. Therefore, this study offers the reader the possible barriers to sustainable digital servitization with Industry 4.0 perspective implementations and comprehensive solutions for these barriers. In addition, this study draws a roadmap for disseminating digital service applications.

Originality/value

There is no study, to the best of the authors’ knowledge, about determining barriers and problems with merging digital servitization with the Industry 4.0 perspective. So, there is still a significant gap in the literature about investigating these two essential topics from the Industry 4.0 perspective.

Abstract

Purpose

This study aims to investigate the contribution of knowledge-intensive business services firms to small- and medium-sized manufacturers’ digital servitization journeys, addressing the standardization versus customization dichotomy of services and solutions provision.

Design/methodology/approach

To identify the challenges that small- and medium-sized firms must face in the digital servitization journey and the role that knowledge-intensive business services firms may play in the innovation processes, the authors conduct a review on two still unrelated literature streams and develop a longitudinal single-case study, with a particular focus on knowledge generation mechanisms.

Findings

Digital servitization is a particularly challenging transformational journey for minor firms. Knowledge-intensive business services firms can act as sources, facilitators, and carriers of knowledge, and they can orchestrate further contributions of other external partners and firms.

Research limitations/implications

The paper contributes to theory describing the roadmap and the role of external service providers in digital servitization journeys of smaller firms’, that are frequently excluded from mainstream research although being the backbone of European economies.

Practical implications

Digital servitization in minor manufacturing firms requires a long-term orientation and a multi-stage roadmap. Mixing standardized technology-based solutions and complementary professional services, knowledge-intensive business services firms can significantly contribute to lowering the journey’s uncertainties, operational complexity, and costs.

Originality/value

The paper sheds lights on how the collaboration between knowledge-intensive business services firms and small manufacturers generates novel knowledge and capabilities that contribute to takle the challenges of the different stages of the digital servitization roadmap.
