This study examines the impact of family involvement in ownership and control on firms’ R&D intensity, relying on panel data on publicly held firms in Canada over the 2004 to 2009 time period. The literature on the link between family firms and R&D is unclear: although some characteristics may promote R&D intensity in family firms, others factors may have a negative effect. Thus, the authors propose a theoretical framework whereby differences in R&D intensity between family and nonfamily firms are explained based on key conditions, including time horizon, agency costs, resource endowment, or risk-taking behavior. The findings of this study show that publicly traded family firms in Canada record lower R&D intensity compared with nonfamily firms and, therefore, support one side of the previous literature over the other.

We examine the effect of combining internal and external R&D loci on innovation performance in family firms (FF) and nonfamily firms (non-FFs). Our longitudinal analysis of 27,438 firm-year observations of Spanish manufacturing firms from 1990 to 2016 shows that FFs can better exploit the benefits of simultaneously engaging in internal and external R&D activities, leading to a positive effect on innovation performance. Moreover, the relationship between combined internal and external R&D and innovation performance in FFs is contingent upon firm economic performance. By pointing to the importance of taking into account the combination of internal and external R&D loci to foster innovation in FFs, we challenge current family business innovation research.
