Abstract

We study the impact of incumbents' and own patents on entry in pharmaceutical submarkets in the USA for the period 1988-1998. We relate the variation in the effect of patents on entry to some observable market and firm characteristics and find a negative impact of incumbents' patents on entry, which confirms the role of patents as a barrier to entry.
