Ethnic inventors, diversity and innovation in the UK: evidence from patents microdata

Nathan, Max - London School of Economics (LSE) - 2011

Ethnic inventors play important roles in US innovation systems, especially in high-tech regions like Silicon Valley. Do … ‘ethnicity-innovation’ channels exist elsewhere? This paper investigates, using a new panel of UK patents microdata. In theory …, ethnicity might affect positively innovation via ‘star’ migrants, network externalities from co-ethnic groups, or production …

Knowledge disclosure, patents and optimal organization of research and development

Bhattacharya, Sudipto; Guriev, Sergei - London School of Economics (LSE) - 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 nonverifiable interim knowledge exclusively to one of two competing Development Units (DUs) via one of two alternative modes: an Open sale...

How special is the special relationship?: using the impact of R&D spillovers on UK firms as a test of technology sourcing

Griffith, Rachel; Harrison, Rupert; Van Reenen, John - London School of Economics (LSE) - 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 we...

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...

Identifying technology spillovers and product market rivalry

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...

Identifying technology spillovers and product market rivalry

Bloom, Nick; Schankerman, Mark; Van Reenen, John - London School of Economics (LSE) - 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...

Knowledge flow and sequential innovation: implications for technology diffusion, r&d and market value

Belenzon, Sharon - London School of Economics (LSE) - 2006

It is shown that spillovers can enhance private returns to innovation if they feed back into the dynamic research of …” knowledge is reabsorbed by its inventor. A simple model of sequential innovation with dynamic spillovers is developed, which …
