Defensive Strategies in the Quality Ladders

  • Ledezma, Ivan

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.
