This paper investigates the effects on total factor productivity (TFP) in the South of technology developed in the North that is diffused through international trade, foreign direct investment (FDI) and international call traffic (telephone communications). For each developing country in the...

This paper investigates similarities and differences between developed and less developed countries in international technology diffusion. We measure international technology spillovers in trade, patents, and in disembodied forms. We find that all countries benefit from foreign technology....

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...

The "market for innovation" - the sale and licensing of patents - is an often discussed source of incentives to invest in R&D. This article presents and estimates a model of the transfer and renewal of patents that, under some assumptions, allows us to quantify the gains resulting from the...

Economists devote too much attention to international flows of goods and services and not enough to international flows of ideas. Traditional trade flows are an imperfect substitute for flows of the underlying ideas. The simplest textbook trade model shows that a welfare-enhancing move toward...

The "market for innovation" -- the sale and licensing of patents -- is an often discussed source of incentives to invest in R&D. This article presents and estimates a model of the transfer and renewal of patents that, under some assumptions, allows us to quantify the gains resulting from the...

We study the global innovation and diffusion of ideas by introducing trade into the model in Eaton and Kortum (1999) (EK). This extension allows us to use international trade flows and country-level factor costs to estimate both the intensity of innovation within countries over time and...
