R&D collaborations that combine resources and exploit complementary expertise contribute to the successful creation and implementation of new knowledge. Collaborative R&D may further be a way in which firms cope with financing constraints. Based on panel data for a large sample of R&D-active firms, findings provide empirical support for this hypothesis. Results show that collaborating firms rely less on internal funding for research than others even when accounting for firms’ selection into collaborations.
