Monopoly versus R&D-integrated Duopoly

In the standard two‐stage framework of R&D/product market competition, this paper provides a performance comparison between monopoly and the cartelized research joint venture, using two well‐known models based on different versions of the R&D spillover process. According to the model with a wider scope of application, monopoly always leads to a higher propensity for R&D and, when R&D costs are low, to the best overall market performance. The results also allow for a comparison between the two underlying models of strategic R&D.
