Hedging stock market prices with WTI, Gold, VIX and cryptocurrencies: a comparison between DCC, ADCC and GO-GARCH models
Authors: Fakhfekh Mohamed , Jeribi Ahmed , Ghorbel Ahmed , Hachicha Nejib 
Published: May 2021

PurposeIn a first place, the present paper is designed to examine the dynamic correlations persistent between five cryptocurrencies, WTI, Gold, VIX and four stock markets (SP500, FTSE, NIKKEI and MSCIEM). In a second place, it investigates the relevant optimal hedging strategy.Design/methodology/approachEmpirically, the authors examine how WTI, Gold, VIX and five cryptocurrencies can be applicable to hedge the four stock markets. Three variants of multivariate GARCH models (DCC, ADCC and GO-GARCH) are implemented to estimate dynamic optimal hedge ratios.FindingsThe reached findings prove that both of the Bitcoin and Gold turn out to display remarkable hedging commodity features, while the other assets appear to demonstrate a rather noticeable disposition to act as diversifiers. Moreover, the results show that the VIX turns out to stand as the most effectively appropriate instrument, fit for hedging the stock market indices various related refits. Furthermore, the results prove that the hedging strategy instrument was indifferent for FTSE and NIKKEI stock while for the American and emerging markets, the hedging strategy was reversed from the pre-cryptocurrency crash to the during cryptocurrency crash period.Originality/valueThe first paper's empirical contribution lies in analyzing emerging cross-hedge ratios with financial assets and compare hedging effectiveness within the period of crash and the period before Bitcoin crash as well as the sensitivity of results to refits choose to compare between short term hedging strategy and long-term one.
On the road to digital servitization – The (dis)continuous interplay between business model and digital technology
Authors: Chen Yihua , Visnjic Ivanka , Parida Vinit , Zhang Zhengang 
Published: May 2021

PurposeThe authors seek to understand the process of digital servitization as a shift of manufacturing companies from the provision of standard products and services to smart solutions. Specifically, the authors focus on changes in the business model (i.e. the value proposition, the value delivery system and the value capture mechanism) for digital servitization.Design/methodology/approachThe authors examine a Chinese air conditioner manufacturer, Gree, who became the global leader with their smart solutions. These solutions included performance-based contracts underpinned by artificial intelligence (AI)-powered air conditioners that automatically adjust to environmental changes and are capable of remote monitoring and servicing thanks to its Internet of things (IoT) technology.FindingsTo successfully offer smart solution value propositions, a manufacturer needs an ecosystem value delivery system composed of suppliers, distributors, partners and customers. Once the ecosystem relationships are well aligned, the manufacturer gains value with multiple value capture mechanisms (i.e. efficiency, accountability, shared customer value and novelty). To arrive at this point, a manufacturer has to pass through different stages that are characterized by both discontinuous and continuous interplay between business models and digital technologies. At the beginning of each stage, new value propositions and value delivery systems are first discontinuously created and then enabled with digital technology. As a result, new value capture mechanisms are activated. Meanwhile, the elements of the existing business model are continuously improved.Research limitations/implicationsBy combining process-perspective and business-model lenses, the authors offer nuanced insights into how digital servitization unfolds.Practical implicationsExecutives can obtain insights into the business model elements, they need to change over the course of digital servitization and how to manage the process.Originality/valueA longitudinal case study of a traditional manufacturer that has achieved stellar success through digital servitization business models development.

Authors: Xu Jinou , Pero Margherita Emma Paola , Ciccullo Federica , Sianesi Andrea 
Published: May 2021

PurposeThis paper aims to examine how the extant publication has related big data analytics (BDA) to supply chain planning (SCP). The paper presents a conceptual model based on the reviewed articles and the dominant research gaps and outlines the research directions for future advancement.Design/methodology/approachBased on a systematic literature review, this study analysed 72 journal articles and reported the descriptive and thematic analysis in assessing the established body of knowledge.FindingsThis study reveals the fact that literature on relating BDA to SCP has an ambiguous use of BDA-related terminologies and a siloed view on SCP processes that primarily focuses on the short-term. Looking at the big data sources, the objective of adopting BDA and changes to SCP, we identified three roles of big data and BDA for SCP: supportive facilitator, source of empowerment and game-changer. It bridges the conversation between BDA technology for SCP and its management issues in organisations and supply chains according to the technology-organisation-environmental framework.Research limitations/implicationsThis paper presents a comprehensive examination of existing literature on relating BDA to SCP. The resulted themes and research opportunities will help to advance the understanding of how BDA will reshape the future of SCP and how to manage BDA adoption towards a big data-driven SCP.Originality/valueThis study is unique in its discussion on how BDA will reshape SCP integrating the technical and managerial perspectives, which have not been discussed to date.
Transformational leadership and organizational performance of Omani SMEs: the role of market orientation
Authors: Dahleez Khalid Abed , Abdelmuniem Abdelfattah Fadi 
Published: May 2021

PurposeThis study proposed and tested a model on the relationship between transformational leadership (TL) and organizational performance (OP) with a possible intervening effect of market orientation (MO) at Omani small and medium enterprises (SMEs).Design/methodology/approachThe study followed a quantitative research design and the deductive approach. Data were collected from 259 employees working in Omani SMEs and were analyzed using structural equation modeling SEM AMOS V24.FindingsThe findings supported positive direct effects of transformational leadership on Omani SMEs' business performance and market orientation. The results also supported the effect of market orientation on business performance. Further analysis showed that market orientation partly mediates the relationship between transformational leadership and business performance.Practical implicationsThe results motivate Omani SMEs' leaders to use intangible capabilities (i.e., market orientation practices) to improve the different aspects of organizational performance. It also suggests that developing SMEs leaders' transformational skills on envisioning the future, adopting open communication styles, motivating employees and stimulating their creativity influences Omani SMEs' performance.Originality/valueDue to the mixed results regarding the TL–OP relationship and the recommendations for further exploring this relationship, this study contributes to theory and practice. It is among the few studies to explore the mediating role of MO between TL and OP in a developing country's SMEs environment.
Ease or excitement? Exploring how concept stores contribute to a retail portfolio
Authors: Egan-Wyer Carys Jane , Burt Steve , Hultman Jens , Johansson Ulf , Beckman Alice , Michélsen Clara 
Published: May 2021

PurposeThe study aims to explore how concept stores (theoretically) differ from other experience-based retail formats, and hence, how they (practically) contribute to a diversified retail store portfolio.Design/methodology/approachCase study based on semi-structured, qualitative interviews with seven IKEA retail managers, three industry experts and 26 customers of IKEA concept stores in London and Stockholm.FindingsThe concept store represents a conceptual departure from other experiential store formats. It is neither fully experiential in the sense that it is not only about marketing communications nor is it sales or profit-focused. Its aim is to be an accessible touchpoint that reduces friction on a diversified customer journey with its value to the retail portfolio being that it attracts new and latent customers, mitigates existing inhibiting factors and drives them to other touchpoints.Research limitations/implicationsIdeas about the different characteristics of new store formats and their potential to shape the customer experience are extended. New formats reflect innovation in retailing and are part of a retail portfolio which generates different customer expectations and determinants from traditional store formats which provide the customers' existing reference point.Practical implicationsThe contributions of new formats should be evaluated in light of other existing formats in the portfolio and not isolated. This is particularly true when considering format cannibalisation and the potentially extended customer journey that arises when customers use traditional format stores and new concept format stores simultaneously.Originality/valuePrevious research, using sales metrics and market-based results as performance determinants, suggests negative outcomes for format diversification. Our study suggests that the contributions of the concept store format should be viewed from an overall customer journey perspective and the “performance” of different format based touchpoints are not best captured through traditional sales evaluation methods.
The psychological effect of compensation on decent work dimensions: a research on public and private school teachers in Turkey
Authors: Çolakoğlu Cavit , Toygar Arda 
Published: May 2021

PurposeThe purpose of this work is to examine the psychological impact of adequate compensation, which is one of the dimensions of Decent Work Scale (DWS) evaluated within the psychology of work theory (PWT), on other dimensions of DWS in teachers working in public and private schools in Turkey.Design/methodology/approachIn this study, DWS developed by Duffyet al.was used. In total, 175 private school teachers and 216 public school teachers participated in the study. The data were analyzed with LISREL 8.7 and SPSS 23.0 package programs.FindingsConsidering the structural equation model formed by the sub-dimensions of the DWS and the path diagrams related to the model, it was seen that the “adequate compensation” dimension made a significant difference in “access to health services” on both public and private school teachers. In private school teachers, there is a significant relationship between the dimension of adequate compensation and “access to healthcare”, “physically and interpersonally safe working conditions”, “free time and rest” and “organizational values that complement family and social values”. However, a significant relationship was not found between the variables other than “access to healthcare” in public school teachers. According to the results of the “Independent SampleT-Test”, there is a significant mean difference between the perceptions of teachers working in public and private schools. When this difference is examined, it was seen that teachers working in public schools have a higher level of good job perception than teachers working in private schools.Research limitations/implicationsDWS is a newly developed scale and has been used in a limited number of studies. It is a scale open to be developed and used with different sample groups.Originality/valueApplication of DWS to teachers working in Turkey is one of the fundamental features that distinguish this study from other studies in this area. In addition, the evaluation of the psychological effects of the adequate compensation dimension, which is an important study factor, on the other dimensions of DWS adds originality to the study. It is predicted that this research will fill the deficiency in the relevant literature.
New insights into the nexus between board characteristics and intellectual capital disclosure: the case of the emerging economy of Mauritius
Authors: Mooneeapen Oren , Abhayawansa Subhash , Ramdhony Dinesh , Atchia Zainab 
Published: May 2021

PurposeWe investigate the association between intellectual capital disclosure (ICD) and board characteristics in the unique setting of Mauritius, a Small Island Developing State. The uniqueness of the setting stems from the country's corporate governance landscape, where most companies have female directors and a high proportion of directors with multiple directorships, director independence is symbolic and directors come from a close-knit group.Design/methodology/approachWe use 120 firm-year observations from companies listed on the Stock Exchange of Mauritius from 2014 to 2017. All data is hand collected from annual reports using content analysis method. Panel multivariate regression is used to test the hypotheses with relevant controls, including intellectual capital performance.FindingsICD is negatively associated with board independence and positively associated with gender diversity of the board. No association is found between ICD and the size of the board, multiple directorships or the average tenure of the board members.Originality/valueThis is the first study investigating the association of board gender diversity, multiple directorship and tenure of board members with ICD in annual reports. The relationships observed between board characteristics and ICD highlight the context-dependent nature of these relationships. This study also overcomes the correlated omitted variable bias likely to have affected the analyses in previous studies examining the nexus between board characteristics and ICD through its control for intellectual capital performance.
Environmental management accounting, board role performance, company characteristics and environmental performance disclosure
Authors: Nkundabanyanga Stephen Korutaro , Muramuzi Bruno , Alinda Kassim 
Published: May 2021

PurposeThe increasing environmental challenges require efforts to expand the scope of accounting to better evaluate organizations’ behaviour/practices. This paper aims to report the results of studying the link between environmental management accounting (EMA), board role performance (BRP), company characteristics and environmental performance disclosure (EPD) of Ugandan manufacturing firms.Design/methodology/approachThe study was correlational and cross-sectional. The results are obtained through content analysis of company reports, websites and a questionnaire survey of 102 large and medium manufacturing firms in four districts of Uganda.FindingsResults indicate that EMA causes significant variances in EPD in manufacturing firms. Also, BRP and firm size explain variances in EPD through EMA.Research limitations/implicationsThe research does not control for industry type. Still, the results offer hope on how the reliability of environmental performance information that companies voluntarily provide outside financial statements, can be improved.Originality/valueResults potentially extend available literature by providing a mechanism through which the environmental performance information is obtained for onward disclosure.

Authors: Bakhshi Hossein , Weisi Hiwa , Yousofi Nouroddin 
Published: May 2021

PurposeThis paper explores the challenges of conducting qualitative research from ELT (English Language Teaching) Ph.D. candidates' perspectives.Design/methodology/approachThe participants of the study consisted of 30 Iranian Ph.D. students majoring in ELT. The semi-structured interview was employed to investigate the heart of experiences, issues and concerns of participants with regard to conducting qualitative research (QLR) challenges. To analyze the collected data, the recorded interviews were transcribed, and then the grounded theory approach was employed (Charmaz, 2006).FindingsThe results revealed that the major challenges of the participants consist of the credibility of QLR in ELT contexts, hermeneutic and fuzzy nature of QLR, qualitative data analysis and interpretation, publishing qualitative findings and the system of measuring professors' productivity.Originality/valueThe findings may help professors, mainly EFL ones, in research mentoring and developing research syllabi for graduate students. In addition, it may motivate Ph.D. candidates to employ QLR methods in their research studies. The pedagogical and theoretical implications of the study are discussed at the end of the paper.
Determinants of private domestic investment in Palestine: time series analysis
Authors: Awad Ibrahim M. , Al-Jerashi Ghada K. , Alabaddi Zaid Ahmad 
Published: May 2021

PurposeThis empirical paper aims to examine the impact of interest rate (IR) and political instability (POLINS) on Palestine's domestic private investment.Design/methodology/approachA set of econometric techniques of time series data are adopted to meet the study objectives. They include regression analysis, unit root tests, cointegration test, ARDL & Bound tests, VAR test and Granger causality test.FindingsThe study's primary results complement the neoclassical approach, which states that the IR is negatively associated with domestic private investment. The empirical results reveal that there is no long-run relationship. Also, there is no causality between domestic investment and lending rates. Accordingly, these findings alert policymakers to draw a series of steps to minimize the IR at a minimum to stimulate investment for improved economic growth and development.Practical implicationsThere is still no national currency in Palestine. The Palestinian Monetary Authority (PMA) is advised to set an appropriate ratio of the IR for the currencies-in-circulation in Palestine for boosting investment and economic development.Originality/valueThis paper provides new background information to both policymakers and researchers on the main determinants of investment in Palestine using econometric analysis. Accordingly, this critical issue is required to be examined in Palestine for stimulating investment.
Weathering fluctuations in teacher commitment: leaders relational failures, with improvement prospects
Authors: Price Heather 
Published: May 2021

PurposeStudies demonstrate the central role of principals in developing and sustaining teacher commitment to their school. Teachers' commitment to their school impacts teaching, learning, innovation and school climate and manifests job satisfaction. Commitment strongly relates to teacher attrition. Attrition is important in the study of school success and failure given its strong predictive link to student learning.Design/methodology/approachThis study thus identifies relational practices of principals who successfully develop and maintain high levels of commitment among their teaching staff compared to those principals who fail to maintain high commitment or fail to raise low commitment among their teachers during the school year. To investigate this process, this study uses longitudinal, within-year school network and climate data for teachers and principals in 15 American charter schools. With these data and theories offered by social-psychology and organizational studies, the interpersonal leadership and school climate conditions set forth by the principal link to the fluctuating levels of commitment among teachers.FindingsDespite the consistently established link between employee commitment and organizational success and failure, this operationalization of changing levels of staff commitment is a novel contribution to the discussion of organizational principal leadership failure. This study clearly tests the questions: Which emotional responses prove volatile to teachers' repeated exchanges with their principals? How do principals' relational practices impact teachers' commitment to teaching? Among the strongest findings is the key practice of principals to maintain trust—interpersonal and schoolwide—to improve commitment among teachers and avoid loss of commitment by the end of the school year.Practical implicationsRelational practices of principals can promote quality relationships that uphold trust and sustain environments conducive to maintaining high organizational commitment. When leaders fail to establish and maintain quality relationships, challenges experienced during a school year become more difficult to overcome.Originality/valueThe opportunity arises to test the time-varying aspect of interpersonal relations in organizations and the subsequent idea about how organizational leaders maintain strong relationships, strengthen poor ones or repair injured relationships. These results evidence teacher commitment is prone to decline at the end of the school year yet the chance and magnitude of the fluctuation directly responds to changes in principals' relational practices. With relational practices, principals can induce affective responses from teachers at the interpersonal and organizational level that improve commitment among teachers and reduce drops in commitment.
The elephant in the dark: the social origins of research in nonprofit financial management
Authors: Berkovich Zakhar , Searing Elizabeth A.M. 
Published: May 2021

PurposeThe purpose of this paper is twofold. The first is to map the most influential literature in nonprofit finance and financial management. The second is to understand why the literature has evolved the way it has, including isolated silos developing in certain disciplines.Design/methodology/approachThe review includes articles assembled from three sources: a core list, an expert list and journal archive searches on phrases that emerged. Using social origins theory as a guide, we coded 119 articles for traits such as root discipline, methodology and author characteristics.FindingsResearch tends to stay confined within the doctoral discipline of the author, who publishes in journals valued by their discipline. This has caused limited cross-referencing across disciplines, and it has allowed different understandings and judgments of the same phenomenon to exist in different fields. Data availability drives much of the research agenda, but author teams of mixed disciplines are promising.Originality/valueUnlike a traditional literature review, this study identifies factors that have had a formative influence on the development of the diverse field of nonprofit finance and financial management. This diversity has resulted in a fractured field held in silos with few indigenous developments. Using social origins theory as a guide, this study provides an overview of the most consequential literature through the analysis of authors and institutional characteristics. This approach provides an evolutionary perspective and illustrates how this disciplinary adherence has created a research topography that limits progress for both scholars and practitioners.
