We study how network externalities affect research and development (R&D) investments by a non-cooperative duopoly that offers compatible products. We find that multiple R&D equilibria may arise when network externalities are non linear in the number of consumers. The lowest R&D equilibrium...

We test the theoretical prediction that inter-firm spillovers must necessarily be large for the profit differential between cooperation and non-cooperation in R and D to be monotone increasing with them. By using the French data from the 2002 Community Innovation Survey, we find that spillovers...
