outsource generates slower innovation than vertical integration.
We can conclude that outsourcing is chosen by firms and encourages innovation when there are
substantial gains from specialization (large λ) and the ex post bargaining weights of intermediate
suppliers and final producers tend to reflect the relative incentives of labs to create the correspond-
ing blueprints (ω close to ω*). When this is the case, search and hold-up frictions are minimized.
Thus, by (31), in sectors in which the R&D costs of intermediate blueprints are large (resp. small)
with respect to the R&D cost of final blueprints, outsourcing is likely to accelerate innovation when
the bargaining weight of intermediate suppliers is also large (resp. small) with respect to the bar-
gaining weight of final assemblers. These results are amplified in sectors with pronounced product
differentiation.
5 Conclusion
We have proposed a model of horizontal product innovation with outsourcing to explore the im-
plications of fragmented production for innovation. The model focuses on situations in which the
fragmentation of production leads to complementary innovations by upstream and downstream labs
