By examining a large number of Swedish listed firms, we analyse how institutional and foreign owners affect investment performance. To measure investment performance Mueller and Reardon’s (1993) marginal q is used, although derived directly from Tobin’s average q. Marginal q measures the ratio of the return on investment to the cost of capital. Our findings show that both domestic and foreign institutional owners positively influence firm performance. Furthermore a non-linear relation between institutional ownership concentration and performance is found. This is consistent with positive incentive effects and negative entrenchment effects. During the last decades the ownership structure of Swedish firms has undergone dramatic changes: institutional and foreign investors have been increasing their stakes, whereas Swedish households have decreased in importance. Controlling owners, often founding families, remain in control by resorting to an extensive use of dual-class shares. The practice of dual-class shares which separates cash-flow rights and control rights is also found to be an important determinant of firm performance that eradicates the positive influence of institutional ownership.

The openness of open innovation in ecosystems
Artikel (med peer review)Publikation
Öberg, C., & Alexander, A.



Open innovation has rendered increased interest both in practice and research, and has expanded from dyadic transfers of ideas, to ecosystem levels. Knowledge is at the heart of open innovation, and this paper describes and discusses knowledge-transfer linkages for open innovation. It does so based on a literature review. The paper links together open innovation research with general management research to categorise and discuss linkages among parties in terms of their openness and how they relate to knowledge management. Conclusions indicate that openness needs to be considered in different dimensions that also links to different knowledge management outcomes. The paper’s contribution consists of how it connects open innovation research to the general management literature, and how it builds a practical understanding of how linkages between firms can be categorised to aid firms to consider which mechanisms they may choose and why.

The role of innovation metrics in innovation systems
Artikel (med peer review)Publikation
Öberg, C.



In innovation systems, venture firms, incubators and science parks may interact with universities to achieve commercialisable output. These various parties are connected to different guiding performance metrics — measures on each party’s performance — that influence their behaviours. This paper illustrates and discusses the role of performance metrics among various parties in innovation systems connected with early research ideas from universities. The empirical part of the paper is based on interviews with 20 researchers and 10 representatives of various innovation system organisations in an EU-based research project. The paper points out how parties in the innovation process saw different reasons to participate which were strongly connected with how each party was evaluated and which caused sub-optimisation in behaviours. Previous research on innovation systems has not focused on the rationales and behaviours of parties. The focus on metrics targets an important point for understanding innovation processes involving several parties and specifically doing so for support organisations that cannot be measured on revenues or profits.
