This paper aims to increase our understanding of sustainable business model innovation in the agri-food sector in terms of its theoretical and practical approaches for sustainability and their degree of complexity and maturity. The paper is based on a systematic literature review of 570 journal articles on business models and business model innovation published between 1990 and 2014. Of these articles, only 21 have business model innovation as their main focus. The review shows that research interest in the agri-food sector has increased in these years. The paper proposes a conceptual framework for sustainable business model innovation in the agri-food sector that can be used to meet the challenges encountered in taking a sustainability perspective.

Purpose -Because the business model (BM) is a fairly new concept, research is lacking on business model innovation (BMI) in certain industry sectors. One such sector is the agri-food sector. Using a systematic literature review (SLR) of peer-reviewed journal articles published from 1990 to 2014, the purpose of this paper is to examine the where, when, and how of the use of BMs and BMI in the agri-food sector. Design/methodology/approach -A web-based search was conducted to identify peer-reviewed journal articles that contained a combination of "BM" or "BMI" with agriculture-related and foodrelated terms (e.g. "agri-food sector"). After winnowing out irrelevant and duplicate articles, 505 articles were chosen for analysis. Findings -Using categories, the paper analyses various data about the selected articles. The categories include research settings, units of analysis, methodologies, and theories. Based on this analysis, the paper finds that these agri-food sector articles are primarily qualitative, empirical studies that focus on one or a few companies (i.e. case studies). The paper also finds that theory is not yet well-developed in the research on the agri-food sector. Originality/value -SLRs of various concepts, theories, and models are common in many fields (e.g. information/software technology, healthcare, and organizational management). However, no such review is available for the agri-food sector, in particular in its use of BMs and BMI. This paper addresses that gap with its review of relevant articles published in more than 300 journals in recent years. Based on this review, the paper draws conclusions about BMI in the agri-food sector and offers suggestions for future research.

Companies in the agri-food sector are under increasing pressure to adopt sustainable business models that consider not only economic but also both social and environmental aspects. This paper examines how Swedish food producers use sustainable business models to innovate their businesses. The empirical data comes from a telephone survey with 204 companies and from case studies of 4 companies. A conceptual framework regarding sustainabilityoriented innovation (SOI) and a eight sustainable business model archetypes are used to map and analyse the sustainability innovation practices and the sustainable business models. The results show a surprisingly sustainable business focus taken by many companies, which is not only on optimization, but also on organizational transformation and on systems building. The results show the companies vary as far as which archetypes they match. The most common archetype matches are 'Maximise material and energy efficiency' and 'Adopt a stewardship role'. Only 10% measure success solely in financial terms, while 80% measure success in financial terms as well as social and environmental terms. Another conclusion is that companies in the agri-food sector have unique characteristics and the value intention of the entrepreneurs is an important building block in sustainable business model innovation.

Ideal science should conform to certain criteria or goals, among them the goals of universalism and communality. Realization of these goals may be limited, however, through the dividing up of researchers in terms of geographical borders. In this study the general hypothesis is tested that there is a segmentation of the society of management researchers into a North American (US) and a European (E) segment, a segmentation which is Mhered by differences in incentive schemes and in paradigms. Four leading management journals from North America and from Europe, respectively, and the 242 articles they contained published in 1993 were selected to represent the different geographical segments. The results provide: support for the existence of two such segments; support for differences in incentive schemes influencing the articles; support for their being paradigm differences between the two segments; and support for a paradigm effect being stronger in US-journals than in E-journals, US-authors are more willing, however, to conform to the E-paradigm than vice versa We argue for methodological pragmatism in order to reduce the presumed countepproductive effects of paradigmatic rigidity.
