A note on endogenous spillovers in a non-tournament R&D duopoly

The paper analyzes a simple non-tournament model of R&D where firms are engaged in cost-reducing innovation. It is shown that when spillovers of information are treated as endogenous firms never disclose any of their information when choosing their R&D non-cooperatively. Under cooperative R&D, firms will always choose to fully share their information, i.e., a research joint venture will operate with a maximal spillover value.
