Motivated by empirical features that characterize cryptocurrency volatility data, the authors develop a forecasting strategy that can account for both model uncertainty and heteroskedasticity of unknown form. The theoretical investigation establishes the asymptotic optimality of the proposed heteroskedastic model averaging heterogeneous autoregressive (H-MAHAR) estimator under mild conditions. The authors additionally examine the convergence rate of the estimated weights of the proposed H-MAHAR estimator. This analysis sheds new light on the asymptotic properties of the least squares model averaging estimator under alternative complicated data generating processes (DGPs). To examine the performance of the H-MAHAR estimator, the authors conduct an out-of-sample forecasting application involving 22 different cryptocurrency assets. The results emphasize the importance of accounting for both model uncertainty and heteroskedasticity in practice.

Prior analyses of racial bias in the New York City’s Stop-and-Frisk program implicitly assumed that potential bias of police officers did not vary by crime type and that their decision of which type of crime to report as the basis for the stop did not exhibit any bias. In this paper, we first extend the hit rates model to consider crime type heterogeneity in racial bias and police officer decisions of reported crime type. Second, we reevaluate the program while accounting for heterogeneity in bias along crime types and for the sample selection which may arise from conditioning on crime type. We present evidence that differences in biases across crime types are substantial and specification tests support incorporating corrections for selective crime reporting. However, the main findings on racial bias do not differ sharply once accounting for this choice-based selection.

Looks at the 2000 Employment Research Unit Annual Conference held at the University of Cardiff in Wales on 6/7 September 2000. Spotlights the 76 or so presentations within and shows that these are in many, differing, areas across management research from: retail finance; precarious jobs and decisions; methodological lessons from feminism; call centre experience and disability discrimination. These and all points east and west are covered and laid out in a simple, abstract style, including, where applicable, references, endnotes and bibliography in an easy‐to‐follow manner. Summarizes each paper and also gives conclusions where needed, in a comfortable modern format.

This chapter explores how quality is assessed in craft beer through describing tastes and aromas in relationship to categories of beer style. Drawing on documentary sources, it explores the development and formalisation of definitions of beer styles, and the development of the contemporary language used to describe and assess taste. It then ethnographically explores how these are combined in the practice of craft beer judging at a competition through a novel assemblage of different methods. The empirical work contributes novel methods for exploring tasting practices, detailed ethnographic description of beer judging and an exploration of how the organisation of style guides and taste descriptions have contributed to defining and assessing quality in craft beer.

We live in the Age of Knowledge, which is impelling us towards the Age of Imagination. The technological wave rises and with it rises a wave of change that will affect both the economy and society. When these two waves will reach the coast where knowledge meets ignorance, and how to ride them, are questions that require us to imagine the future. We must, therefore, embark on the vessel of imagination, leaving behind us the baggage of what we know and understand. Imagination is not just the springboard for ideas; it also acts to connect ideas in different ways that may blossom in the garden of an entrepreneurial renaissance. Symbols, metaphors and concepts that belong to our tacit knowledge come to light in our memory. It is from here that the imagination draws its lifeblood, broadening our horizons, inducing us to interact with others who may be the bearers of other cultures. Are we ready to engage in an imaginative learning process to join business with innovation and art? Are we prepared to design a wide-open white space where the actors of entrepreneurship, innovation and art can generate a constructive tension that will sweep away what appears to be mutual antagonism or incompatibility?

After his studies of economics and business administration at the Technical University of Dortmund he received his PhD (1996) and Habilitation (2000) degree at the same University, Faculty of Business Administration, Chair of Strategic and International Management. From 2000 to 2002 he worked as a visiting research scholar and visiting professor for strategic management and organizational theory at the J.L. Rotman School of Management, University of Toronto, Canada. Afterward he became professor of international management and business policy at the University of Stuttgart. In 2004 he took a professorship of strategic management at the CASS Business School, City University of London, UK. Up till today, he is visiting professor for General Management and International Strategy. Between 2006 and 2009 he held the chair for management and international strategy at the University of Kaiserslautern. He has written several books, for example! Strategisches Management. Theoretische Grundlagen-Prozesse-Implementierung (together with M. K. Welge), Organisationales Wissensmanagement. Vahlens Handbücher der Wirtschafts- und Sozialwissenschaft, Praxis des strategischen Managements (together with M. K. Welge and P. Kajüter) and Strategieprozesse in deutschen Unternehmungen. His current research focuses on evolutionary dynamics in the German biotech-industry, alliances and network dynamics as well as the internationalization of SME.

This paper aims to contribute toward the extension and further development of the social exchange theory. It provides conceptual insights on social networks in geographically dispersed organizations, and how intra-organizational social interactions influence organizational behavior, employees relationship exchange inclination and innovation drive.

A thematic literature review method was used to conduct an extensive review of relevant literature.

Guided by the tenets of the social exchange theory, the authors’ analysis and discussions elucidate how intra-organizational social network architecture can be developed, supported and utilized to drive innovations in geographically dispersed organizations.

A general limitation and perhaps also a strength of this type of conceptual paper is that it is a synthesis (thematic discursive analysis) of existing theory and published research. Thus, there are no primary empirical content. However, the issue of empirical evidence is nevertheless mediated by the fact that the discussions and argumentation process generate key propositions which could be validated in subsequent research endeavors. Also, the selection of relevant literature is restricted specifically to the topic of the study. The authors strived to ensure rigor through a robust and comprehensive literature review which was organized thematically according to all the key words in the main and sub-topics covered in Section 2.

The insights presented suggest that management should pay serious attention to organizational design – that is, not only from the conventional contractual obligations point of view, but rather, the increasing importance of social capital should also be given some priority when thinking of resilient ways to encourage collaborations and efficient knowledge management. In other words, intra-organizational social network architecture should be considered as organizational capability and utilized as a toolset for the SIHRM to harness knowledge flow and unleash innovation.

As both bonding and bridging ties are not only critical for success of project teams but also intensify knowledge symmetry across different units of the organization, they are a major conduit for sustainable open innovation culture within organization. To develop competitive capabilities throughout the organization, it is important for the SIHRM to be involved in global networking, and as a network leader, the human resource management function must have an awareness of leading trends and developments in social networking. The ability to mobilize the appropriate resources and a sense of timing and context in implementing such architecture within the geographically spread organization is crucial.

The novel contribution of this paper is twofold. First, the study provides an implementable framework which scholars and practitioners could use to develop and test the actualization of an intra-organizational social network architecture in a geographically dispersed organization. Second, the study has provided some key propositions and a well-grounded direction for further research to inspire further development/extension of the social exchange theory.
