This research investigates recent trends and developments in the scope and impact of international collaboration in research publications. A number of prior studies in the field of Research & Development (R&D) have outlined the factors influencing an increasing internationalization in R&D. We transfer these findings in a complete sample of publication data from the years 2008–2015 in order to find out and describe how researchers in the two academic fields Health Care/Clinical Medicine and Business & Economics collaborate with foreign-based colleagues. We analyze how this research by international teams performs in terms of received citations, compared to their national counterparts. We find that international teams generally receive more citations than national ones. Furthermore, we outline how the number of countries with relevant publication numbers has grown and diversified over the last years, and author teams generally became larger and more international. In a last step, we show how emerging countries built up competence and knowledge over time, as an increase in received publication citations follows at a delayed pace to an increase in publication numbers. While there are some differences between the two academic fields Health Care/Clinical Medicine and Economics & Business, with, for example the former having approximately around ten times more publications per year, than the latter, the major structural trends and developments are similar in both fields, outlining the robustness of our analysis.

Concerns about sustainability challenges are growing. Companies are under pressure to rethink existing innovation paradigms. In this context, research interest in the resource-constrained innovation concept, frugal innovation, has increased. In this paper, we examine the impact of frugal innovation on the economic, social, and ecological sustainability dimensions by conducting a systematic literature review of 44 papers. We find that frugal innovation is a promising approach to promote sustainable development from an economic perspective and a social perspective. Nevertheless, positive and negative effects exist in all three dimensions. Thus, a positive relationship is not inherent but must be proactively formed. External factors can influence the impact of frugal innovation on sustainability. For future research we recommend (1) establishing a unified understanding of frugal innovation through a clear definition, (2) broadening the research focus to a global perspective, (3) assessing the impact of frugal innovation along the entire product life cycle, and (4) investigating characteristics that make frugal innovation sustainable.
