Identifying technology spillovers and product market rivalry
Bloom, Nick; Schankerman, Mark; Van Reenen, John - London School of Economics (LSE) - 2005
Government policies to support R&D are predicated on empirical evidence of R&D "spillovers" 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 general...

Bloom, Nick; Schankerman, Mark; Van Reenen, John - London School of Economics (LSE) - 2013
The impact of R&D on growth through spillovers has been a major topic of economic research over the last thirty years. A central problem in the literature is that firm performance is affected by two countervailing "spillovers" : a positive effect from technology (knowledge) spillovers and a...

The impact of private ownership, incentives and local development objectives on university technology transfer performance
Belenzon, Sharon; Schankerman, Mark - London School of Economics (LSE) - 2007
We study the impact of private ownership, incentive pay and local development objectives on university licensing performance. We develop and test a simple contracting model of technology licensing offices, using new survey information together with panel data on U.S. universities for 1995-99. We...
