Many writers have claimed that R&D has two 'faces'. In addition to the conventional role of stimulating innovation, R&D enhances technology transfer by improving the ability of firms to learn about advances in the leading edge ('absorptive capacity'). In this paper we document that there has...

This paper presents a unified model that integrates the theoretical literatue on Schumpeterian endogenous growth, the microeconometric literature on R&D and productivity, and the empirical literature on productivity convergence. Starting from a structural model of endogenous growth following...

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...

We examine the economic analysis of the relationship between innovation and product market competition. First, we give a brief tour of the intellectual history of the area. Second, we examine how the Aghion-Howitt framework has influenced the development of the literature theoretically and...

We examine the home bias of knowledge spillovers (the idea that knowledge spreads more slowly over international boundaries than within them) as measured by the speed of patent citations. We present econometric evidence that the geographical localization of knowledge spillovers has fallen over...

This paper investigates whether there is convergence in Total Factor Productivity towards the technological frontier at the establishment level. We find convergence to the frontier is statistically and quatatively important, suggesting the existence of technology spillovers. Foreign...

This paper examines the relationship between foreign ownership and productivity, paying particular attention to two issues neglected in the existing literature Ö the role of multinationals in service sectors and the importance of R&D activity conducted by foreign multinationals. We review...

This paper investigates the relationship between export market shares and relative unit labour costs using a long panel of twelve manufacturing industries across fourteen OECD countries. We ask two questions: (a) how sensitive are export market shares to changes in relative costs and (b) what...

Patents citations are a potentially powerful indicator of technological innovation. In this paper we describe the IFS-Leverhulme patents dataset that we have constructed by combining information from the US Case-Western Patent database with UK company accounts and share price information from...
