We consider an industry composed of two types of firms, namely, innovators that invest in process research and development (R&D), and surfers that do not but benefit from knowledge spillover.We verify if the conclusions reached in the seminal paper by d’Aspremont and Jacquemin hold in this setting.We obtain that cooperation among innovators still lead to higher R&D and output levels than when they do not cooperate.Our main result is that the presence of surfers in an industry can be welfare improving under some conditions.
