Defensive Strategies in the Quality Ladders

(english) This paper analyses the potentially defensive behaviour of patent race winners and its effect on aggregate R&D effort. It proposes a quality-ladders model that endogenously determines leaders technology advantages and who innovates. Product market regulation can have either a positive or a negative effect on R&D intensity. The negative effect is likely to be observed in highly deregulated economies. The positive influence arises in more regulated environments and it is stronger for larger innovative jumps. These steady-state equilibrium outcomes are consistent with puzzling and contrasting patterns stemming from data on manufacturing industries for 14 OECD countries during the period 1987-2003. _________________________________ (français) Dans cet article nous étudions le comportement potentiellement défensif des innovateurs et son effet sur l’effort agrégé d’innovation. Un modèle à échelles de qualité est proposé afin d’analyser l’émergence d’avantages technologiques qui, in fine, déterminent qui innove (le leader ou ses concurrents). Dans ce contexte, la réglementation de marché peut avoir un effet positif ou négatif sur l’intensité en R&D. Elle peut être négativement associée à l’effort d’innovation dans des environnements hautement dérèglementés. Par contre, en économies qui dépassent un certain seuil de réglementation, susceptible de limiter effectivement la construction de barrières stratégiques, la réglementation induit des incitations à innover. Ces prédictions sont cohérentes avec des tests empiriques menés sur un échantillon d’industries appartenant à 14 pays de l’OCDE durant la période 1987-2003.
