This paper develops and analyzes a macroeconomic model in which aggregate growth and fluctuations arise from the discovery and diffusion of new technologies; there are no exogenous aggregate shocks. The temporal behavior of aggregates is driven by individuals' efforts to innovate and/or make use...

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...

This paper develops a theory of total factor productivity differences in a framework of technology diffusion. I show how in countries with tighter borrowing constraints, frontier technologies diffuse more slowly, and old outdated technologies continue to be used. I analyse how countries with...

Innovation is an inherently risky and uncertain process. Many of the broader challenges to innovation in general are both mirrored and exaggerated in environmental innovation. The four primary issues are externalities, uncertainty, asymmetric information, market power. Green technology is...

This article presents new international estimates of human capital for the period 1970–2003. The new latent index is used to re-examine the Benhabib and Spiegel (2005) model of technology diffusion in a horse-race with the competing indicators of Barro and Lee (2010) and Hanushek and Wößmann...

Although innovation diffusion is a central topic in policy and strategy, its measurement remains difficult – particularly in cases where the innovation is a complex and possibly ambiguous practice. In this paper, we develop four theoretical mechanisms that may bias diffusion markers by leading...

This paper quantifies the effect of state privacy regulation on the diffusion of Electronic Medical Records (EMR). EMR allow medical providers to store and exchange patient information using computers rather than paper records. Hospitals may be more likely to adopt EMR if they can reassure...

Does the disclosure requirement of the patent system encourage the diffusion of inventions? This paper builds a simple model where firms choose between patents and trade secrecy to protect inventions. Diffusion is not necessarily more likely with a patent system nor is the "market for...

We find that the effects of parent firm R & D on plant-level productivity are diminished by both the geographic and technological distance between the research lab and the plants, that productivity appears to depend on R & D per plant rather than on the total amount, and that spillovers from...
