The paper extends a theoretical framework for analyzing competition and innovation in presence of horizontal spillovers. Introducing two scenarios, it is shown that when firms behave non-cooperatively in both the R&D and production stages the degree of spillover has a negative relationship with...

The paper formalizes, in a rigorous manner, the concept of information externalities, by modeling R&D activities as the process of searching for a drug to treat a disease, with R&D activities being modeled from the perspective of the theory of optimal search. In conventional models of patent...

The paper extends a theoratical framework to analyze the impact of R&D spillovers on entry and the resulting equilibrium market structure. It is shown that the degree of spillovers plays a fundamental role on the number of firms entering the market, their R&D activities, and social welfare. The...

We consider a licensing mechanism for process innovations that combines a license auction with royalty contracts to those who lose the auction. Firms’ bids are dual signals of their cost reductions: the winning bid signals the own cost reduction to rival oligopolists, whereas the losing...

This paper reconsiders the licensing of a common value innovation to a downstream duopoly, assuming a dual licensing scheme that combines a first-price license auction with royalty contracts for losers. Prior to bidding firms observe imperfect signals of the expected cost reduction; after the...
