The seven articles contained in the special issue ‘Fostering Cross-Disciplinarity in Business Model Research’ are summarised, and the authors’ perspectives on the phenomena studied as well as the theories and methods adopted are portrayed. Methodology: We provide literature-based definitions of cross-disciplinary research modes and discuss their potential for business model research informed by insights from the seven special issue articles. Findings: There is much variety regarding the theories applied in business model research. These include design, imprinting, information asymmetry, paradox theories and many more. This variety illustrates that traditional domains, such as organisation, management and entrepreneurship studies, can be extended in creative ways, and hence can be equipped to deal with emerging and complex issues such as sustainability, circular economy, data management and base-of-the- pyramid entrepreneurship. Interdisciplinarity seems to be well developed regarding the use of theories, but more must follow in terms of research methods and collaboration formats. Research Implications and Limitations: The common understanding of the potential and importance of cross-disci- plinarity can be considered the major implication of this special issue. Beyond this, further critical reflection is required. Important questions remain open, primarily regarding research methods and collaboration formats. This editorial article reflects the perspectives of both the guest editors and the authors in this special issue. The presented understandings of cross-disciplinary business model research and implications for its future are of a preliminary nature. Originality and Value: Business model research is growing rapidly and scholars from various fields contribute to expanding our knowledge. An explicit focus on the potential of multi-, inter- and transdisciplinary research approaches is missing so far.

It is remarkable that this research field attracts researchers from many diverse disciplines, including management and organisation studies, entrepreneurship and innovation, industrial design, information technologies, engineering, sociology, sustainability studies and many more (e.g. Dentchev et al., 2018; Foss and Saebi, 2017; Massa et al., 2017; Maucuer and Renaud, 2019; Wirtz and Daiser, 2018). This involvement of multiple disciplines speaks not only to the inherent complexities of business models (cf. Massa et al., 2018) but also to the richness and potential of this research field. Referring to the latter, we can state that business model research holds potential for cross-disciplinary modes of knowledge generation, bringing together researchers from more than one discipline to investigate a specific phenomenon (Mennes, 2020). For example, several disciplines deal with shared or recurring business model phenomena from their individual perspectives, which allows juxtaposing their specific insights (e.g. what management scholars discover about business model innovation compared to what designers can tell us). However, despite, or maybe because of, this situation there seems to be a tendency towards ‘silo-building’ in business model research, hampering progress towards other, more integrative, cross-disciplinary modes, including multi-, inter- and transdisciplinary research. Let us look at two recent developments. First, silobuilding takes place between different business model (sub-)communities. We see at least one community dealing with ‘traditional’ or ‘mainstream’ business models, and another one interested in ‘new’ or ‘sustainable’ business models. The existence of two conference series—International Conference on New Business Models and Business Model Conference—is an indication of these different communities.1 Similar patterns can be found in the topics typically discussed in leading journals such as Long Range Planning and Journal of Management on the one hand and Organization & 1 See http://businessmodelconference.com/ and https://www. newbusinessmodels.org/ Environment and Journal of Cleaner Production on the other hand. Second, silo-building takes place within these communities as well, as researchers tend to limit themselves to discipline-specific phenomena, theories and methods and fall back to their camps in the multidisciplinary spectrum. Such a tendency is natural since specialisation in once-acquired knowledge and skills together with subordination to given cultures of research, hierarchies and knowledge structures are key features of disciplines (cf. Turner, 2017) and serve the very pursuit of an academic career (Aagaard-Hansen, 2007). As a consequence, we observe some hesitation with regard to the development and application of more diverse cross-disciplinary research modes (cf. Mennes, 2020). As guest editors of this special issue, we wondered: What if we could make use of the richness and potential of various streams of business model research early on, before specialisation turns into unsurmountable barriers, and help researchers from different disciplines to connect and learn from each other? This may have been a naïve stance, but we insisted on giving it a chance and hence called for contributions showcasing crossdisciplinary research in business models applied to diverse topics and phenomena (e.g. paradoxes of business model development and performance, disruptive business models and industry dynamics, ecological and social entrepreneurship, business models for sustainability transitions and so on)—referred to as ‘multi- and interdisciplinary’ in the original call for papers.2 Our aim was to explore the variety of current business model research and to motivate cross-disciplinary exchange to make sure that progress in specialised streams of business model research translates into progress of the field as a whole. We deliberately invited participants from both 2019 business model conferences to submit their papers to this special issue. Let us take stock of what we did and did not find. But before, we briefly explain our understanding of crossdisciplinarity in business model research and why striving to overcome silos and disciplinary boundaries is a worthwhile endeavour. 2 See http://www.journalofbusinessmodels.com/media/1253/cfpfostering-multi-and-interdisciplinary-business-model-research. pdf Journal of Business Models (2021), Vol. 9, No. 2, pp. i - xiv iii Why Strive to Overcome Silos and Disciplinary Boundaries? In 2011, Zott, Amit and Massa found that the business model literature was ‘developing largely in silos, according to the phenomena of interest to the respective researchers. The main interest areas identified were (1) e-business and the use of information technology in organizations, (2) strategic issues, such as value creation, competitive advantage, and firm performance and (3) innovation and technology management’ (Zott et al., 2011, p. 1019). From more recent reviews we can conclude that this tendency is becoming more pronounced and that other special interest groups, such as entrepreneurship and sustainability researchers, are adding new camps to the business model research landscape (e.g. Dentchev et al., 2018; Foss and Saebi, 2017; Lüdeke-Freund and Dembek, 2017; Massa et al., 2017; Maucuer and Renaud, 2019). Increasing specialisation within a maturing research field is undoubtedly necessary to gain more detailed insights into its phenomena, improve its research methods and theories, discover new ones, and, in general, make use of efficient division of labour and variety in perspectives. In a similar vein, Lecocq et al. (2010) argued for the advantages of developing a ‘research programme’ for business models, which was followed by Nielsen et al.’s (2018) four distinct phases of business model research. In particular, the first phase focuses on definitions and conceptualisations of business models as well as the links between business models and strategies. The second phase is dominated by the research stream of business model innovation. The design of frameworks and the foundations for theory-building are at the core of the third phase. The fourth phase is centred on the performative approach. Studies in this phase explore what actually happens in companies when business model tools are designed, implemented and used (e.g. what works and what does not work, levers and barriers of designing, implementing and using business model tools; see Montemari, 2018). Research adopting a performative approach builds on the assumption that business models are context-dependent and are given meaning by subjects in the specific situations in which they are developed and applied (Roslender and Nielsen, 2019). Taking these developments in business model research into consideration, this special issue builds on the conviction that the increasing specialisation and search for a research programme should be complemented by a search for cross-disciplinary approaches (cf. Mennes, 2020) or, at least, the openness to look beyond disciplinary boundaries. Our assumption is that cross-dis- ciplinarity improves our understanding of phenomena, methods and theories, particularly regarding complex questions that scholars aim to address, for example, how entrepreneurial values motivate the shape and performance of ecologically and socially beneficial business models. Finding answers to questions such as this one requires expertise from diverse fields (e.g. entrepreneurship, psychology and sustainability). Cross-dis- ciplinary approaches (in contrast to mono-disciplinary approaches) should be better suited to grasp these issues and to study business models as they actually are: complex and multi-dimensional systems (Massa et al., 2018). As such, business models integrate human interactions, organisational structures, markets and diverse stakeholders, and thus, they typically cross the boundaries of various social, economic and technological systems, for example, by connecting supply and demand, technologies and markets, stakeholders and value creation and so on (for exemplary overviews of the variety in business model research see Lüdeke-Fre- und and Dembek, 2017; Dentchev et al., 2018; Maucuer and Renaud, 2019). Accordingly, Maucuer and Renaud suggest that ‘disciplines should cross-fertilize in order to enrich their own conceptualization [of business models] and reinforce the co-development of their respective fields … [and to] combine their efforts in developing transversal issues …’ (Maucuer and Renaud, 2019, p. 38). The benefits of such an approach can be illustrated with another example: Some researchers work on the cognitive micro-foundations of business model development and propose that these involve configurations of simple design and decision-making rules, so-called heuristics (Loock and Hacklin, 2015), or schemas representing firms’ value-creating activities (Martins et al., 2015; Massa et al., 2017). Such cognitive perspectives are also important to understand how actors deal with ambiguous and even paradoxical issues, such as integrating sustainability considerations into business activities (Hahn et al., 2014). In turn, how such challenges can be Journal of Business Models (2021), Vol. 9, No. 2, pp. i - xiv iv addressed effectively by developing new business models is a question that may be answered by building on two decades of research on business model innovation (Foss and Saebi, 2017; Wirtz, Göttel et al., 2016, Wirtz, Pistoia et al., 2016). Business model researchers have a natural tendency to deal with complex and multidimensional issues (cf. Massa et al., 2018) involving multiple stakeholders’ needs and interests (Lüdeke- Freund et al., 2020) and hence require correspondingly integrative and diverse research modes. What is Cross-Disciplinarity? We follow Mennes (2020) and use the term cross-dis- ciplinarity ‘to refer to the general category of research that involves more than one discipline’ (p. 3). Dominating taxonomies of cross-disciplinarity typically distinguish three modes. The following definitions proposed by Mennes particularly highlight the role of collaboration: • ‘‘multidisciplinarity’ refers to the collaboration of researchers with different backgrounds where their respective disciplines are juxtaposed instead of integrated …; • ‘interdisciplinarity’ stands for the collaboration of researchers with different disciplinary backgrounds where (elements of) the respective disciplines are integrated …; and • ‘transdisciplinarity’ either refers to a collaboration where the integration of (elements from) different disciplines is so extensive that the origin of the elements gets lost, or refers to a collaboration of researchers and non-academics such as stakeholders and/or practitioners who integrate their knowledge and know-how.’ (p. 4–5) Multidisciplinarity is typically described as juxtaposing different disciplines (Klein, 2017; Vermeulen and Witjes, 2021). The involved disciplines, for example, innovation management and psychology, remain separate and their characteristics, such as theories and methods, retain their original identity. This research mode involves different approaches to studying shared phenomena, for example, how entrepreneurs come up with new business models. While innovation management scholars and psychologists may both study this phenomenon, the theories and methods they use and the knowledge they generate remain within their respective disciplinary boundaries. The obtained results will be complementary and may even be combined in a joint framework, but they will only be loosely related and presented in a sequential or encyclopaedic manner. The multidisciplinary research mode leads to multiple perspectives on jointly studied business model phenomena, but it does not foster theoretical or methodical integration. By contrast, interdisciplinarity is characterised by proactive integration and interaction between disciplines (Klein, 2017; Vermeulen and Witjes, 2021). Methods and concepts are borrowed from other disciplines to test hypotheses, develop new theories and find answers to research questions that require the knowledge and skills from more than one discipline. Such approaches are driven by, for example, the complexities of natural and social phenomena, the search for solutions to societal problems and technological change. For example, innovation management scholars can borrow psychological concepts, such as values and motivation, to study the antecedents and moderators of entrepreneurs’ sustainability-oriented business model innovation processes. Beyond ‘borrowing’, researchers may cross disciplinary boundaries—in fact, create new disciplines—by proactively integrating their approaches and developing new theoretical constructs and empirical methods. Psychologically enhanced innovation theories and empirical investigations of ‘values-based business model innovation’ (e.g. Breuer and Lüdeke- Freund, 2017) or the development of new reference frames for ‘sustainability-oriented business models’ (e.g. Dentchev et al., 2018) serve as examples. Attributes associated to transdisciplinarity include ‘hyper-integrative’ (Mennes, 2020), ‘transcending’ and even ‘transgressive’ (Klein, 2017). While interdisciplinarity crosses boundaries by being integrative and interactive, transdisciplinarity goes further in that the original characteristics of involved disciplines may even disappear. The use of transdisciplinary inquiry aims to reach such integration at multiple levels of abstraction (Max-Neef, 2005). Such overarching synthesis can lead to new sciences, such as anthropology as the science of humans, universal ‘interlanguages’ that transcend not only disciplines but also science, education and practical application (e.g. mathematics or system theory), and the redefinition of hierarchies, structures and actor roles in Journal of Business Models (2021), Vol. 9, No. 2, pp. i - xiv v the creation and application of knowledge. Transdisciplinarity is driven by the quest for systematically integrated and universal knowledge, critical evaluation of theories, concepts and methods as well as the underlying sociopolitical antecedents. Transdisciplinary research driven by environmental and sustainability issues (Schaltegger et al., 2013; Vermeulen and Witjes, 2021), for example, acknowledges the ‘life-worlds’ of humans, and not disciplinary interests, as frames for the definition of research problems and knowledge production. New forms of collaboration between academics, business and other social actors, in which scientifically reliable knowledge is merged with socially robust problem definitions and knowledge, are another result of the search for more integrative and universal modes of research. Mono-disciplinarity represents an ‘opposite’ research mode in which scholars apply a rather limited or focused perspective to investigate a phenomenon. However, one must bear in mind that a clear differentiation between these different research modes is difficult to achieve and is context dependent. It is not difficult to see that cross-disciplinary research holds some potential for contemporary business model studies as these often require, at least theoretically, cross-disciplinary collaboration, diverse theories and methods and new ways of dealing with complex phenomena such as innovation, entrepreneurship and sustainability. In the following, we briefly summarise the articles and key findings of the special issue articles and how researchers deal with various phenomena and use diverse theories and methods. These articles’ contributions to, and implications for, cross-disciplinarity in business model research are discussed in the final section. Articles in the Special Issue This special issue contains seven articles, all of which provide inspiration for, and contribution to, future crossdisciplinary conversations and projects in the field of business model research. Table 1 provides an overview of these articles, the diversity of phenomena studied and the variety of applied theories and methods. The short paper by Dror Etzion (2020), ‘Radical Resource Productivity as an Inspiration for Business Model Innovation: The Case of Foodchain’, addresses business model innovations in the service sector. Foodchain is a fastcasual restaurant recently founded in Montreal, Canada, with the primary aim of serving uncooked, vegetablebased meals. The research objective is to understand the effects of waste-minimisation efforts, following a radical resource productivity (RRP) approach on business model design. A major RRP design choice was to use so-called Robot-Coupes for food production, which increases efficiency gains in earlier manufacturing-like stages of the value chain. Furthermore, an activity map was found to be a useful tool to visualise essential business model design choices and consequences. The article by Michael Fruhwirth, Christiana Ropposch, and Viktoria Pammer-Schindler (2020), ‘Supporting Data-Driven Business Model Innovations: A Structured Literature Review on Tools and Methods’, reviews research on tools and methods for data-driven business model innovation. The analysed literature is structured according to the types of contribution (taxonomies, patterns, visual tools, methods, IT tools and processes), types of thinking supported (divergent and convergent) and the business model elements that are addressed (value creation, value capturing and value proposition). By drawing on these findings, the authors identify three avenues for future research: first, tools and methods that enable convergent thinking require additional studies; second, more research is needed to provide a holistic view that integrates single tools and methods; and third, designing software tools to support data-driven business model innovation is an area that should be further investigated. The article by Martin Glinik, Michael Rachinger, Christiana Ropposch, Florian Ratz, and Romana Rauter (2021), ‘Exploring Sustainability in Business Models of Early-Phase Start-up Projects: A Multiple Case Study Approach’, explores the drivers for integrating sustainability aspects in the business models of early-stage start-ups. The authors studied the sustainability in the business models of six early-stage entrepreneurial projects. They found that most cases indicate that early-stage start-ups do not holistically integrate sustainability, but rather consider it as an additional benefit to their products and services. The authors assert that the main drivers of sustainable business models in early-stage ventures are entrepreneurial motivation, careful resource use and waste reduction. Both Journal of Business Models (2021), Vol. 9, No. 2, pp. i - xiv vi altruistic and strategic, respectively financial motivations were found to be important for the inclusion of sustainability considerations. The article by Päivi Luoma, Anne Toppinen, and Esko Penttinen (2021), ‘The Role and Value of Data in Realising Circular Business Models: A Systematic Literature Review’, is positioned at the crossroads between circular business models and data. It studies the role that data, such as supply-chain and life-cycle data, plays in circular business models. The review shows that this role is still poorly understood. The recognition of data as both driver and enabler for circular economic activities is common. Additionally, two approaches Author(s) and title Phenomena studied Theories and methods used Etizon, D.

The article by Niklas Endregat and Bartjan Pennink (2021), ‘Exploring the Coevolution of Traditional and Sustainable Business Models: A Paradox Perspective’, uses seven case studies to investigate the tensions and paradoxes that occur when traditional and sustainability-oriented business models co-evolve under one corporate roof. The identified tensions and paradoxes include competing demands in terms of performance and value creation, fit with organisational culture and mindset, challenges in training and staffing, the allocation of resources between traditional and sustainable business models and balancing the roles and expectations of multiple stakeholders. The authors present a framework to structure these challenges and to analyse their sample of cases. Four coping strategies are identified: ‘splitter’, ‘operational perfectionist’, ‘strategic mandator’ and ‘transformer’. The article by Claudia Alba Ortuño and Nikolay Dentchev (2021), ‘We Need Transdisciplinary Research on Sustainable Business Models’, argues in favour of transdisciplinarity in sustainable business model research. The authors developed their arguments based on a transdisciplinary programme in Bolivia and 57 interviews and 10 focus group discussions with vulnerable entrepreneurs and relevant stakeholders, alongside numerous on-site observations. The authors used the theoretical lens of information asymmetry and argue that transdisciplinary research can resolve the problems of moral hazard, information analysis and information access, which occur while investigating complex phenomena, such as sustainable business models. Based on the findings of this study, the authors make five suggestions for how scholars can adopt transdisciplinarity in their sustainable business model studies: (i) understand the context, (ii) adapt to the context, (iii) develop relationships of trust, (iv) be flexible with the research focus and (v) systematically present to other disciplines and non-academic actors. The article by Sophie Urmetzer (2021), ‘Dedicated Business Models – Connecting Firms’ Values with the Systemic Requirements of Sustainability’, brings together insights from innovation system theory, sustainability transitions and innovation trajectories. The main finding is that dedicated business models affect an innovation system at the level of its leading paradigms. These business models commit to sustainability values, increase their influence through expansion of their networks and actively impose these sustainability values on consumers and suppliers. The theorical link this paper explores between innovation system and transition theories culminates in the role business models play as a linking pin to shape and instigate change at a fundamental level. More in-depth insights into diffusion mechanisms and patterns of values, and how these reconfigure leading paradigms at regime and systems levels, call for the inclusion of additional disciplines (e.g. social psychology, innovation management). Implications and Potential for Cross-Disciplinarity in Business Model Research The goal of this special issue is to illustrate the variety of phenomena studied by business model scholars and to shed light on the diversity of theories and methods they apply. While this special issue can of course only offer a very limited snapshot, it covers diverse topics including business model design, entrepreneurship, sustainability and data and analytics, in addition to diverse combinations of these topics. Several indications of cross-disciplinarity in studying these topics can be found in the articles, mostly in terms of interdisciplinary approaches to defining phenomena under investigation and to using theory. We discuss the implications of these observations in more detail below. In addition to our reading of the articles, we asked the authors to appraise their research modes, using a simple continuum ranging from mono- to multi-, inter- and transdisciplinarity. The authors were provided with the definitions of research modes proposed by Mennes (2020) (see the ‘What is Cross-Disciplinarity?’ section). Figure 1 demonstrates how the authors appraised their own work by responding to the following question: Journal of Business Models (2021), Vol. 9, No. 2, pp. i - xiv viii ‘Please position your paper along the continuum from mono- to transdisciplinary. The cross-disciplinary aspects of your research approach adopted could refer to, for example, theories, methods, collaboration processes, or disciplinary backgrounds of the authors.’ According to the authors, most of the studies presented in the special issue involve interdisciplinary research modes. Acknowledging that interdisciplinarity seems to be a common research mode applied by the special issue authors and that future research should be more transdisciplinary, we reflect on some implications for cross-disciplinarity in business model research. We focus on the four most prominent topics covered in our special issue, namely business model design, entrepreneurship, sustainability and data and analytics. In doing so, we also present the authors’ points of view. Asked for their key learnings, they offered some interesting insights and explanations for why crossdisciplinarity makes sense in the context of business model research. Business model design Many special issue articles deal with topics related to business model design, including business model innovation, design principles and methods and tools for business model development. Business model design is a ‘hot topic’ in business model research, exemplified by a constantly growing number of journal articles focusing on it (e.g. Wirtz and Daiser, 2018). In this special issue, it is addressed from various theoretical perspectives, including engineering- and sustainability-inspired approaches to resource use (Etzion, 2020), imprinting theory to explain organisational behaviour (Glinik et al., 2021), data- and analytics-enabled Figure 1: Research modes adopted and thematic areas covered in the special issue articles (according to the authors) Note: (1) Etzion; (2) Fruhwirth, Ropposch and Pammer-Schindler; (3) Luoma, Toppinen and Penttinen; (4) Glinik, Rachinger, Ropposch, Ratz and Rauter; (5) Endregat and Pennink; (6) Alba Ortuño and Dentchev; (7) Urmetzer
