Convergence in per capita income turns on whether technological knowledge spillovers are global or local. Global spillovers favor convergence, while a geographically limited scope of knowledge diffusion can lead to regional clusters of countries with persistently different levels of income per...

This paper presents a model of international trade in differentiated intermediate goods. Because intermediates are invented through costly R&D investments, employing foreign intermediates implies sharing the return to R&D with the inventor country. We first derive how domestic productivity is...

We estimate international technology spillovers to U.S. manufacturing firms via imports and foreign direct investment (FDI) between 1987 and 1996. In contrast to earlier work, our results suggest that FDI leads to substantial productivity gains for domestic firms. The size of FDI spillovers is...

We study international technology transfer through R&D spillovers in sixteen countries' manufacturing industries since the early 1970s. The analysis shows that the productivity impact of international technology transfer often exceeds that of domestic technological change, more so in...

This paper examines how international flows of technological knowledge affect economic performance across industries and firms in different countries. Motivated by the large share of the world's technology investments made by firms that are active across borders, we focus on international trade...

Convergence in per capita income across countries turns on whether technological knowledge spillover are global or local. This paper estimates the amount of spillover from R&D expenditures in major industrialized countries on a geographic basis. A new data set is used which encompasses most of...

I present a model of R&D-driven growth which predicts that technology, in form of product designs and created through R&D investments, is transmitted to other domestic and foreign sectors by being embodied in differentiated intermediate goods. Empirical results are presented employing data from...

In this paper we emphasize the contribution of technical change, broadly defined, towards productivity growth in explaining the relative East Germany-West Germany performance during the post-World War II era. We argue that previous work was excessively focused on physical capital investments...

This chapter examines how international flows of technological knowledge affect economic performance across industries and firms across different countries. Motivated by the large share of the world's technology investments made by firms that are active across country borders, we focus on...

In this paper, I analyze recent findings by Coe and Helpman (1995) of trade-related international R&D spillovers. I show generally that randomly created bilateral trade shares also give rise to large estimated international R&D spillovers; often, in fact, to larger estimated spillover effects...
