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...

This paper examines the impact of fiscal incentives on the level of R&D investment. An econometric model of R&D investment is estimated using a new panel of data on tax changes and R&D spending in nine OECD countries over a nineteen year period (1979-1997). We find evidence that tax incentives...

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...

We examine the "technology sourcing" hypothesis that foreign research labs located in the U.S. tap into U.S. R&D spillovers and improve home country productivity. We show that U.K. firms that established a high proportion of inventors based in the U.S. by 1990 benefited disproportionately from...

How much does US-based R&D benefit other countries and through what mechanisms? We test the "technologysourcing" hypothesis that foreign research labs located on US soil tap into US R&D spillovers and improvehome country productivity. Using panels of UK and US firms matched to patent data we...
