This paper presents an endogenous growth model that explains the evolution of the first and second moments of productivity growth at the aggregate and firm level during the post-war period. Growth is driven by the development of both (i) idiosyncratic R&D innovations and (ii) general innovations...

We introduce a tractable model of endogenous growth in which the returns to innovation are determined by the technology adoption decisions of the users of new technologies. Technology adoption involves an implementation investment that determines the initial productivity of a new technology....

Can a country grow faster by saving more? We address this question both theoretically and empirically. In our model, growth results from innovations that allow local sectors to catch up with the frontier technology. In relatively poor countries, catching up with the frontier requires the...

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...

We present a tractable model for analyzing the relationship between economic growth and the intensive and extensive margins of technology adoption. The “extensive" margin refers to the timing of a country's adoption of a new technology; the “intensive" margin refers to how many units are...

Tourism is a tradable service activity that could allow some African countries to generate significant growth. Tanzania, given its unique natural assets, is an ideal candidate. However, despite being so richly endowed in touristic resources, Tanzania receives very few tourists and revenues from...
