Even though every decision a leader makes carries an element of risk, no review on the topic of leadership and risk has appeared in highly-ranked management journals in the past 20 years. This is in contrast to the discipline of psychology in which leadership and risk receives considerable attention, particularly in the field of heroism studies. In the context of the established body of research on the topic of leadership and risk in the discipline of psychology, this review therefore explores the research on leadership and risk in highly-ranked management studies’ journals.

The review was conducted in five stages. During phase 1, journal rankings were used as basis to determine which highly-ranked journals to include in the review. Phase 2 focused on identifying all relevant articles in the journals included in our review. We searched for articles published from 2000 to 2021 with the words “risk” or “danger” and “leader” or “leadership” in their abstracts. In phase 3, the author analysed the abstracts of the articles in depth to determine whether the keywords were included on the basis of an explicit scholarly reflection or research on leadership and risk. Phase 4 focused on analysing articles' treatment of leadership and risk, and assigning key words and key phrases. Finally, during phase 5 key words and key phrases were clustered together thematically.

This study analysis yielded six thematic clusters. The first two clusters – on risk appetite of followers and leaders – are closely related. In total, 12 journal articles explored these themes. The remaining thematic clusters contain four and seven articles each. These clusters are risk, creativity and innovation; risk and failure; risk in dangerous contexts; and risk and gender. Nine of the selected articles did not fit in any of the thematic clusters.

The review reveals a significant lack of research on leadership and risk in highly-ranked management studies’ journals. The author found that the topic of leadership and risk is approached in a binary fashion: successful leaders are viewed as using risk to drive innovation and unsuccessful leaders fail because of risk. The author argues that the heroic bias in leadership research could be partly blamed for this binarism. In practical terms, the author highlights that the growing importance of chief risk officers – leaders appointed to deal with company risk – indicates a clear need for research on leadership and risk in general management studies’ journals.

Research on grand challenges in the management literature is vibrant and growing. Given that the term “grand challenges” was first invoked in our field 10 years ago, it is timely to reflect on how we came to this point – and where we might go from here. In this article, we first explore the origins of the concept of grand challenges in order to trace core assumptions and developments and understand how they shape the current conversation about grand challenges in management scholarship. We next convey findings from our review of 161 papers that cite the editorial for a grand challenges special issue (George, Howard-Grenville, Joshi, & Tihanyi, 2016), uncovering four ways in which papers are shaping the conversation on grand challenges. Finally, based on our perspective on how we got here and where we are now, we make several suggestions for what should come next in driving forward research on grand challenges. We urge scholars to go beyond the study of collaboration for tackling grand challenges and shift toward a more critical, yet generative, exploration of their construction, persistence, and unintended consequences. We also call for increased attention to theorizing grand challenges to guide practitioners’ understanding of the nature of the thing they are trying to address. In these ways, we hope to inspire management scholars to leverage expertise on processes – not content per se – that shape how grand challenges manifest and how they may be tackled.

This paper provides a methodological map for guiding the choice and application of research paradigms and design frames that can be of value to a wide range of researchers in the fields of education, social sciences and interdisciplinary studies who are interested in teaching and learning in context. Following an interpretivist/constructivist paradigm, I used a mixed methods research approach to study the spatial experiences of Emirati female students in a gender--‐ segregated educational context. The main component was qualitative, using ethnography, while the quantitative part included a survey. In such a research approach, my reflexivity and unique positionality as both insider and outsider played a significant role. The paper is divided into three sections: the beginning, which justifies the choice and philosophies of the methodological route; the journey, which illustrates the data collection techniques; and the destination, containing reflexive lessons from the field.

Working conditions on many digital work platforms often contribute to the grand challenge of establishing decent work. While research has examined the public regulation of platform work and worker resistance, little is known about private regulatory models. In this paper, we document the development of the “Crowdwork Agreement” forged between platforms and a trade union in the relatively young German crowdworking field. We find that existing templates played an important role in the process of negotiating this new institutional infrastructure, despite the radically new work context. While the platforms drew on the corporate social responsibility template of voluntary self-regulation via a code of conduct focusing on procedural aspects of decent platform work (i.e., improving work conditions and processes), the union contributed a traditional social partnership template emphasizing accountability, parity and distributive matters. The trade union’s approach prevailed in terms of accountability and parity mechanisms, while the platforms were able to uphold the mostly procedural character of their template. This compromise is reflected in many formal and informal interactions, themselves characteristic of a social partnership approach. Our study contributes to research on institutional infrastructures in emerging fields and their role in addressing grand challenges.
