Spillover of research and development (R&D) in industries with a few big players can impact how firms decide to invest in new technologies. This study looked at a game involving two firms where they first choose whether to do R&D and then compete in the market. The research compared how much firms invest in R&D when they have different levels of information about their rivals' ability to benefit from their R&D. The results show that having more information about how much your competitor can benefit from your R&D can have a mixed effect on how much firms invest in new technologies.
