Growth Through Heterogeneous Innovations
Akcigit, Ufuk; Kerr, William R. - Census Bureau, Department of Commerce - 2012
We study how exploration versus exploitation innovations impact economic growth through a tractable endogenous growth framework that contains multiple innovation sizes, multiproduct firms, and entry/exit. Firms invest in exploration R&D to acquire new product lines and exploitation R&D to...

Competition, imitation, and R&D productivity in agrowth model with sector-specific patent protection
Mosel, Malte - 2009
Recent empirical studies suggest a need for a flexible patent regime responding to industry characteristics. In practice, sector-specific modifications of patent strength already exist but lack theoretical foundation. This paper intends to make up for this neglect by scrutinizing in what...

On scale effects, market power and growth when human and technological capital are complements

Growth effects of non proprietary innovation
Saint-Paul, Gilles - 2002
We study an endogenous growth model where a profit-motivated R and D sector coexists with the introduction of free blueprints invented by philanthropists. These goods are priced at marginal cost, contrary to proprietary ones which are produced by a monopoly owned by the inventor. We show that...
