Expansion in mobile phone coverage has improved access to information throughout the developing world, particularly within sub-Saharan Africa. The existing evidence suggests that information technology has improved market efficiency and reduced consumer prices for certain commodities. There are...

The US has experienced a sustained increase in productivity growth since the mid-1990s, particularly in sectors that intensively use information technologies (IT). This has not occurred in Europe. If the US “productivity miracle” is due to a natural advantage of being located in the US then...

We construct a model that combines elements of endogenous growth with the convergence implications of the neoclassical growth model. In the long run the world growth rate is driven by discoveries in those economies that lead in their use of technology. Followers converge towards leaders because...

The purpose of this paper is to link the propensity for innovative activity to cluster spatially to the stage of the industry life cycle. The theory of knowledge spillovers, based on the knowledge production function for innovative activity, suggests that geographic proximity matters most in...

The recent emergence in the industrial organization literature of a wave of studies identifying small firms as being at least as innovative as their larger counterparts poses something of a paradox. Where do small firms get their knowledge generating inputs? The purpose of this paper is to link...

We study the determinants of the diffusion of mobile telecommunications services in the European Union in a logistic model of technology diffusion. We find that the transition from the analogue to the digital technology during the early nineties, and the corresponding increase in spectrum...

We analyze the joint dynamics of religious beliefs, scientific progress and coalitional politics along both religious and economic lines. History offers many examples of the recurring tensions between science and organized religion, but as part of the paper’s motivating evidence we also...

Understanding the impact of legal protection on investment is of major importance. This paper provides a framework for addressing this issue, and shows that investment may actually be higher in the absence of legal protection. Focusing on the application to innovation, in an environment where an...

We measure the impact of a drastic new technology for producing steel, the minimill, on the aggregate productivity of U.S. steel producers, using unique plant-level data between 1963 and 2002. We find that the sharp increase in the industry's productivity is linked to this new technology, and...

This chapter discusses different approaches pursued to explore three broad questions related to technology diffusion: what general patterns characterize the diffusion of technologies, and how have they changed over time; what are the key drivers of technology, and what are the macroeconomic...
