Identifying Technology Spillovers and Product Market Rivalry
Bloom, Nicholas; Schankerman, Mark; Van Reenen, John - C.E.P.R. Discussion Papers - 2005
Support for many R&D and technology policies relies on empirical evidence that R&D ‘spills over’ between firms. But there are two countervailing R&D spillovers: positive effects from technology spillovers and negative effects from business stealing by product market rivals. We develop a...

Growth Effects of Non-Proprietary Innovation
Saint-Paul, Gilles - C.E.P.R. Discussion Papers - 2001
We study and endogenous growth model where a profit-motivated R&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...

How Special is the Special Relationship? Using the Impact of US R&D Spillovers on UK Firms as a Test of Technology Sourcing
Griffith, Rachel; Harrison, Rupert; Van Reenen, John - C.E.P.R. Discussion Papers - 2004
How much does US-based R&D benefit other countries and through what mechanisms? We test the ‘technology sourcing’ hypothesis that foreign research labs located on US soil tap into US R&D spillovers and improve home country productivity. Using panels of UK and US firms matched to patent data...

Strategic R&D Location by Multinational Firms: Spillovers, Technology Sourcing and Competition
Belderbos, Rene; Lykogianni, Elissavet; Veugelers, Reinhilde - C.E.P.R. Discussion Papers - 2005
We analyse strategic interaction in R&D internationalization decisions by two multinational firms competing both abroad and in their home markets and examine different incentives for foreign R&D faced by technology leaders and technology laggards. The model takes into account the impact of local...

Knowledge Disclosure, Patents and Optimal Organization of Research and Development
Bhattacharya, Sudipto; Guriev, Sergei - C.E.P.R. Discussion Papers - 2004
We develop a model of two-stage cumulative research and development (R&D), in which one Research Unit (RU) with an innovative idea bargains to license her non-verifiable interim knowledge exclusively to one of two competing Development Units (DUs) via one of two alternative modes: an open sale...

Patent Renewals and R&D Incentives
Cornelli, Francesca; Schankerman, Mark - C.E.P.R. Discussion Papers - 1998
In a model with moral hazard and assymmetric information, we show that it can be welfare-improving to differentiate patent lives when firms have different R&D productivities. A uniform patent life provides excessive R&D incentive to low-productivity firms, and too little to high ones. The...
