Coordination costs: a drawback for research joint ventures?

We analyze a simple oligopoly model where firms can engage in cost- reducing R&D. We compare two R&D regimes: R&D competition and R&D cooperation where firms can enter in a Research Joint Venture (RJV). We introduce coordination costs for the RJV and examine how these affect the equilibrium outcomes. Further, we examine the ques- tion of the equilibrium versus optimal size of the RJV. For a given size of the RJV, its members decrease their own R&D as the anticipated coordination costs increase. This results in lower output and profits. On the contrary, the non-RJV firms increase their R&D investments in response to the fall in the RJV firms' R&D.We show that the per- formance of the RJV in terms of R&D investment, profit and welfare in relation to R&D competition is sensitive to the level of coordination costs. Furthermore, we show that, although the RJV as a whole may no longer conduct a unit of R&D at a lower cost compared to the in- dependent firm under the non-cooperative R&D regime, its members can still make savings on their own R&D expense through information sharing. Finally, we find that not only the equilibrium size becomes smaller as coordination costs increase, but the discrepancy between the equilibrium and optimal sizes is widening. One important message from our analysis is that by ignoring the coordination costs of oper- ating the RJV, the anticipated benefits or success of the cooperative project could have been grossly exaggerated
