Cooperative and non-cooperative R&D and trade costs

We examine the effect of trade liberalization on the level and mode of R&D in an international duopoly setting. Firms have the choice to invest in R&D either independently or cooperatively. A reduction in trade cost increases R&D irrespective of the mode of R&D. However, an increase in spillovers has ambiguous effects on R&D. More precisely, we find that an increase in spillover leads to higher R&D activity under cooperation but lower R&D activity under non-cooperation. Concerning cooperation versus non-cooperation, we find that firms prefer cooperation only if trade costs are low. Consumers are better off under cooperation if spillovers are high. We find that there can be a mismatch between private and social incentives. If spillovers are low and trade costs are low then cooperation might be privately profitable but socially undesirable. On the other hand, if there are large spillovers and high trade costs then cooperation may be socially desirable but not privately profitable.
