Financial Development and Technology Diffusion
By: Diego Comin and Ramana Nanda
We examine the extent to which financial market development impacts the diffusion of 16 major technologies, looking across 17 countries, from 1870 to 2000. We find that greater depth in financial markets leads to faster technology diffusion for more capital-intensive... View Details

Ratcheting, Competition, and the Diffusion of Technological Change: The Case of Televisions Under an Energy Efficiency Program
By: Tomomichi Amano and Hiroshi Ohashi
In differentiated goods markets with societal implications, quality standards are commonly implemented to avoid the under-provision of innovation. Firms have clear incentives to engage in strategic behavior because policymakers use market outcomes as a benchmark in... View Details

The Diffusion of New Technologies
By: Aakash Kalyani, Marcela Carvalho, Nicholas Bloom, Tarek Hassan, Josh Lerner and Ahmed Tahoun
We identify phrases associated with novel technologies using textual analysis of patents,
job postings, and earnings calls, enabling us to identify four stylized facts on the diffusion of jobs
relating to new technologies. First, the development of economically... View Details

Scale versus Scope in the Diffusion of New Technology: Evidence from the Farm Tractor
By: Daniel P. Gross
Although tractors are now used in nearly every agricultural field operation and in the production of nearly all crops, they first developed with much more limited application. Early diffusion was accordingly rapid in these narrower applications but limited in scope... View Details

An Exploration of Technology Diffusion
By: Diego Comin and Bart Hobijn
We develop a model that, at the aggregate level, is similar to the one sector neoclassical growth model, while, at the disaggregate level, has implications for the path of observable measures of technology adoption. We estimate our model using data on the diffusion of... View Details

The Spatial Diffusion of Technology
By: Diego A. Comin, Mikhail Dmitriev and Esteban Rossi-Hansberg
We empirically study technology diffusion across countries and over time. We find significant evidence that technology diffuses slower to locations that are farther away from adoption leaders. This effect is stronger across rich countries and also when measuring... View Details
