PurposeThe purpose of this study is to empirically examine the efficiency of Greek fixed-odds (offline) betting market as offered by OPAP for the period 2016–2019.Design/methodology/approachUsing a four-year data sample of OPAP's opening and closing odds for football matches from all over the world and applying linear probability and probit models, the market efficiency is examined and the existence of possible anomalies is investigated.FindingsThe main findings of research suggest that although the odds are dominated primarily by favorite-longshot bias and secondarily by draw bias, this mispricing cannot prove profitable. However, the opening odds, the margin levels and the market structure provide information that is not fully captured by the closing odds, giving bettors profit opportunities. Thus, findings show that the semi-strong market efficiency is questionable. Finally, competition reduces commissions leading to more efficient odds.Practical implicationsThe conclusions of this study are useful for football betting market and, particularly, for government authorities, bookmakers and bettors. Findings can be extended in future research to prediction tasks.Originality/valueTo the best of the authors’ knowledge, this is the first study about the Greek football betting market. The contribution to the literature lies on the one hand in the examination of a monopolistic land-based betting market, which is being squeezed and threatened by the more competitive online betting market, and on the other hand in the simultaneous examination of the opening and closing odds.

Purpose The purpose of this paper is to summarise and reflect upon key issues at the interface of prices, information and regulation with a focus upon the stock market in context. Reflecting upon academic research in the area of efficient markets, and regulatory policy, the concern is to discern issues in terms of policy and support for policy. What does the research imply for policy? Is it possible that the research, perhaps given its rhetoric, can be misinterpreted in relation to policy? The study is also concerned to develop avenues for future research based on these considerations. Design/methodology/approach The paper is an analytical and critical review and writing. Findings The reading of the research suggests a pragmatic regulatory policy that should be concerned to improve stock market functioning, including with respect to information, as well as the context of which this is part. At the same time, the literature may be read as promoting anti-regulatory policy. Practical implications On the one hand, these are consistent with the pragmatic policy referred to above. On the other hand, further research is suggested to explore substantively the rhetoric of the research and its interpretation and to explore understandings of the research and its implications amongst key constituencies in practice. Originality/value The concern is to bring key insights from the academic literature together with a view to promoting a pragmatic policy orientation, while cautioning in a critical perspective about how this academic literature and research might be interpreted from a policy perspective.

Purpose The purpose of this paper is twofold: first, to understand data management challenges in e-maintenance systems from a holistically viewpoint through summarizing the earlier scattered research in the field, and second, to present a conceptual approach for addressing these challenges in practice. Design/methodology/approach The study is realized as a combination of a literature review and by the means of analyzing the practices on an industry leader in manufacturing and maintenance services. Findings This research provides a general understanding over data management challenges in e-maintenance and summarizes their associated proposed solutions. In addition, this paper lists and exemplifies different types and sources of data which can be collected in e-maintenance, across different organizational levels. Analyzing the data management practices of an e-maintenance industry leader provides a conceptual approach to address identified challenges in practice. Research limitations/implications Since this paper is based on studying the practices of a single company, it might be limited to generalize the results. Future research topics can focus on each of mentioned data management challenges and also validate the applicability of presented model in other companies and industries. Practical implications Understanding the e-maintenance-related challenges helps maintenance managers and other involved stakeholders in e-maintenance systems to better solve the challenges. Originality/value The so-far literature on e-maintenance has been studied with narrow focus to data and data management in e-maintenance appears as one of the less studied topics in the literature. This research paper contributes to e-maintenance by highlighting the deficiencies of the discussion surrounding the perspectives of data management in e-maintenance by studying all common data management challenges and listing different types of data which need to be acquired in e-maintenance systems.

Purpose Reviews the latest management developments across the globe and pinpoints practical implications from cutting-edge research and case studies. Design/methodology/approach This briefing is prepared by an independent writer who adds their own impartial comments and places the articles in context. Findings The problem with developing a reputation of being something of an oracle in the business world is that all of a sudden, everyone expects you to pull off the trick of interpreting the future on a daily basis. Like a freak show circus act or one-hit wonder pop singer, people expect you to perform when they see you, and they expect you to perform the thing that made you famous, even if it is the one thing in the world you don’t want to do. And when you fail to deliver on these heightened expectations, you are dismissed as a one trick pony, however good that trick is in the first place. Originality/value The briefing saves busy executives and researchers hours of reading time by selecting only the very best, most pertinent information and presenting it in a condensed and easy-to-digest format.

Purpose – The purpose of this paper is to analyze the different dynamic characteristics of unemployment in a selected group of European Union countries during the current Great Recession, which had unequal consequences on employment depending on the country considered. Design/methodology/approach – The paper follows Shorrocks’s proposal of a duration-sensitive measure of unemployment, and uses cross-sectional data reported by Eurostat coming from European Labour Force Surveys. Findings – The results add some evidence on the relevance of incorporating spells’ duration in measuring unemployment, finding remarkable differences in unemployment patterns in time among European countries. Research limitations/implications – In this paper unemployment is analyzed for all the labor force. Future research should investigate patterns across specific groups such as young people, women, immigrants or the low skilled. Practical implications – It is generally accepted that the negative impact of unemployment on individual welfare can be very different depending on its duration. However, conventional statistics on unemployment do not adequately capture to what extent the recession is not only increasing the incidence of unemployment but also its severity in terms of duration in time of ongoing unemployment spells. The paper shows an easy and practical way to do it in order to improve the understanding of the unemployment phenomenon, using information usually reported by statistical offices. Originality/value – First, the paper provides a tool for dynamic analysis of unemployment based on reported cross-sectional data. Second, the paper demonstrates the empirical relevance of considering spells’ duration when assessing differences in unemployment across countries or in unemployment trends. This is usually neglected or only partially addressed by most conventional measures of unemployment.

Purpose – The purpose of this paper was to explore the Chinese concept of suzhi and how it relates to behavioral standards within mainland Chinese society and the workplace. The article provides a general discussion of suzhi and its inherent elements to act as a foundation for the education of expatriate managers and executives and for future research by Chinese human resource management (HRM) scholars. Design/methodology/approach – This paper draws on the author's first-hand experience and observations from five years of living and working abroad in mainland China with Chinese companies and executives. Findings – The concept of suzhi in China is a reflection of multiple behavioral standards throughout China. And while suzhi's roots are in ancient Chinese culture and Confucianism, it is also subject to influence and change. Practical implications – The paper may serve as a foundation both for expatriate managers seeking to improve HRM practices in foreign companies in China and future scholars who wish to conduct further research on suzhi and Chinese behavioral standards as they can be applied to the workplace. Originality/value – This is an attempt to enlighten expatriate managers and executives in China on the concept of suzhi and its implication for HRM in China.

Practical Implications

Purpose Considering working in the digital age, questions on the consequences for the individual workers are, so far, often neglected. The purpose of this paper is to deal with the question of whether the digital competences of the workforce is a research topic. The authors argue for the thesis that it is indeed a research topic. Design/methodology/approach In addition to a literature analysis of the top IS, HR, and learning publications, non-scientific sources, as well as the opinions of the authors, are included. The authors’ thesis is challenged through a debate of corresponding pros and cons. Findings The definition of digital competences lacks scientific depth. Focussing on the workforce is valid, as a “lifelong” perspective is not mandatory for research. Digital competence research is a multidisciplinary task to which the IS field can make a valuable contribution. Research limitations/implications Although relevant references are included, some aspects are mainly driven by the opinions of the authors. The theoretical implications encompass a call for a scientific definition of digital competences. Furthermore, scholars should focus on the competences of the workforce, including occupations, roles, or industries. The authors conclude by providing a first proposal of a research agenda. Practical implications The practical implications include the alignment of multiple stakeholders for the design of “digital” curricula and the integration by HR departments of the construct of digital competences, e.g. for compensation matters and job requirements. Originality/value This paper is one of very few contributions in the area of the digital competences of the workforce, and it presents a starting point for future research activities.

Purpose – There are many different conceptualizations to sustainable development and these different approaches may have led to confusion amongst the public. The purpose of this paper is to explore the identities of the term and how the confused identity may be leading to problems for sustainable development efforts. Design/methodology/approach – The design is exploratory, using both secondary and primary data to understand the different sustainable development concepts. Findings – There is no consistent understanding or use of the term “sustainable development” among various groups. Research limitations/implications – Future research should include a larger sample that is more representative of people from different backgrounds and geographical areas. Practical implications – The public is generally willing to support only projects that it understands. Without a clear understanding of sustainable development, the public will be less inclined to support these efforts. Originality/value – This study examines the perceptions and understandings of the term by the general public representing different generations.

Purpose The aim of this paper is to characterize how innovation may happen through cross-functional teams (CFT) in an organization of the public sector. Design/methodology/approach A case study helped to characterize several behavior patterns, team structures and respective links with generating innovation in internal processes and public answering contexts. Findings The results highlight that formal-temporary teams present a higher capacity to generate incremental innovation in products, whereas permanent-informal teams have a higher capacity to generate innovation in the internal processes and public answering contexts. Research limitations/implications The limitations of this research relate to the fact that this is a single case study, and although it is an important case to examine innovation and CFTs, by its very nature, it is not possible to extend and generalize the obtained data to other organizations. The evaluation of its propositions was merely qualitative, and future research is needed to validate its characteristics. Practical implications Several settings of CFTs are presented, as well as their ability to generate different types of innovation, such as the computerization of documents, petitions and papers, which decreases the time to answer the taxpayer. Moreover, CFTs can help to create products, such as computer programs that can be used not only locally but also in several public organizations related to tax management. Originality/value The field research provides the perceptions of the respondents regarding CFT characteristics that can lead to specific types of innovation, as well as the types of products or services that can be generated by these processes.

Purpose – The purpose of the article is to propose and develop a distinct perspective in Islamic marketing research through fusing the Islamic paradigm and the macromarketing theory. Design/methodology/approach – This is a conceptual article that is based on intellectualising and reflecting on differences in understanding what marketing is and what role it plays in society. Findings – The article reveals some commonality of purpose between the macromarketing discipline and Islamic macromarketing, while the latter field of inquiry offers a unique outlook to a number of domain-specific issues. Research limitations/implications – The characterisation of Islamic macromarketing will open new avenues for future research and will make researchers more theoretically sensitive to ontological and epistemological assumptions that underlie marketing investigations. The limitation of the present discussion is that Islamic macromarketing may not have yet emerged as a separate discipline. Additionally, research on genuinely macromarketing issues in Islamic contexts is very sparse. Practical implications – Muslim practitioners and managers are to realise that the means and ends of marketing are better understood if viewed from a broader perspective of marketing's impact and consequences on society. By adopting the Islamic macromarketing perspective, public, societal institutions, business stakeholders, and managers will find a better platform to cooperate on maximising the realisation of hasanah (excellence) for all. Originality/value – This article contributes to the discipline by introducing and characterising a potentially new field of marketing inquiry.

Purpose This study aims to examine intellectual capital disclosure (ICD) on Twitter by 60 of the world’s largest companies and explains the main themes communicated to stakeholders. The second objective is to determine which topics provoke most stakeholders’ reactions. Design/methodology/approach The authors perform content analysis on more than 42,000 tweets to examine ICD practices along with the reactions of stakeholders in the form of retweets and “favorites” toward the information disclosed. Findings Intellectual capital (IC) is an important theme in corporate disclosure practices, as more than one-third of the published tweets refer to IC. The world’s largest companies focus on relational capital information, followed by human and structural capital. The main IC themes disclosed were management philosophy, corporate reputation and business partnering. Tweets related to IC are of greater interest to stakeholders than other tweets and provoke more reactions. There is no complete consistency between the topics most intensively disclosed by companies and those that elicit the most vivid responses from the addressees. Practical implications This study offers an understanding of the world’s largest companies’ practices that refer to ICD via social media and has implications for organizations in the creation and use of communication channels when developing a dialogue with stakeholders on topics regarding IC that may lead to better management of IC performance. Originality/value This paper is a response to the call for studies on ICD via social media, which is strongly highlighted in the recent literature concerning future research on IC and until now was almost absent in the field of business units. This research provides in-depth insights into the use of Twitter to disclose IC elements and indicates which fields and topics of this disclosure provoke stakeholders’ reactions, which is a novelty in ICD studies.
