Research on multiple affiliations in academia forthcoming in "Scientometrics"

This study sheds light on the unexplored phenomenon of multiple institutional affiliations using scientific publications. Institutional affiliations are important in the organisation and governance of science. Multiple affiliations may alter the traditional framework of academic employment and careers and may require a reappraisal of institutional assessment based on research outcomes of affiliated staff. Results for authors in three major science and technology nations (Germany, Japan and the UK) and in three fields (biology, chemistry, and engineering) show that multiple affiliations have at least doubled over the past few years. The analysis proposes three major types of multiple affiliations that depend on the structure of the research sector and its international openness. Highly internationalised and higher education-centred affiliations are most common for researchers in the UK whereas Germany and Japan have stronger cross-sector affiliation patterns. International multiple affiliations are, however, still more common in Germany compared to Japan which is characterised by a domestic, cross-sector affiliation distribution. Moreover, multiple affiliation authors are more often found on high impact papers, particularly in the case of authors from Japan and Germany in the fields of biology and chemistry.

Research and product or process development are two distinct, yet complementary innovation activities. Making use of a specific grant-based policy design that explicitly distinguishes between research projects, development projects, and mixed R&D projects, this study estimates the direct and cross scheme effects on both research and development investments of recipient firms. Positive cross scheme effects can be expected when research and development activities are complementary and financing constraints are more binding for research than for…

Academics are increasingly encouraged to acquire external grants to finance their research, and often hold grants from multiple funders concurrently to ensure the continuity of their work. However, there are concerns that inefficiencies occur when funding is received from multiple sponsors, especially when this originates from different sectors. This study investigates complementarities between public/non-profit and private sector sources of research funding with regard to academic output in terms of publications, research impact and research…

We present empirical evidence suggesting that weak tax enforcement proxied by the extent of tax evasion in a country acts like a lower corporate tax rate in attracting profits of multinational corporations.

This study investigates induced productivity effects of firms introducing new environmental technologies. The literature on within-firm organisational change and productivity suggests that firms can achieve higher productivity gains from adopting new technologies if they adapt their organisational structures. Such complementarity effects may be of particular importance for the adoption of greenhouse gas (GHG) abatement technologies. The adoption of these technologies is often induced by public authorities to limit the social costs of climate…

R&D collaboration facilitates the pooling of complementary skills, learning from the partner as well as the sharing of risks and costs. Research therefore stresses the positive relationship between collaborative R&D and innovation performance. Fewer studies address the potential drawbacks of collaborative R&D. Collaborative R&D comes at the cost of coordination and monitoring, requires knowledge disclosure, and involves the risk of opportunistic behavior by the partners. Thus, while for lower collaboration intensities the net gains can be high,…
