While many studies have looked at innovation and adoption of technologies separately, the two processes are linked. Advances (and expected advances) in a single technology should affect both its adoption rate and the adoption of alternative technologies. Moreover, advances made abroad may affect...

This paper uses patent citation data to study flows of knowledge across time and across institutions in the field of energy research. Popp (2002) finds the level of energy-saving R&D depends not only on energy prices, but also on the quality of the accumulated knowledge available to inventors....

Because of the long-term nature of the climate problem, technological advances are often seen as an important component of any solution. However, when considering the potential for technology to help solve the climate problem, two market failures exist which lead to underinvestment in...

Using patent data from the United States, Japan, and Germany, this paper examines both the innovation and diffusion of air pollution control equipment. Whereas the United States was an early adopter of stringent sulfur dioxide (SO2) standards, both Japan and Germany introduced stringent nitrogen...

Recent attempts to endogenize technology in climate policy models have produced mixed results. Models including alternative technologies find large gains from induced technological change. However, technological progress in these models comes through learning-by-doing, which ignores the...

When studying solutions to long-term environmental problems such as climate change, it is important to consider the role that technological change may play. Nonetheless, to date few economic models of climate change explicitly model the link between policy and technological change. There is a...

Despite growing empirical evidence of the link between environmental policy and innovation, most economic models of environmental policy treat technology as exogenous. For long-term problems such as climate change, this omission can be significant. In this paper, I modify the DICE model of...

Although economists cite potential gains from induced innovation as an advantage of using market-based mechanisms to protect the environment, counts of patents related to flue gas desulfurization units ('scrubbers') peaked before trading of sulfur dioxide (SO2) permits began. This paper uses...

I use U.S. patent data from 1970 to 1994 to estimate the effect of energy prices on energy-efficient innovations. Using patent citations to construct a measure of the usefulness of the existing base of scientific knowledge, I consider the effect of both demand-side factors, which spur innovative...

Using an original data set of both scientific articles and patents pertaining to alternative energy technologies, this paper provides new evidence on the flows of knowledge between university, private sector, and government research. Better understanding of the value of knowledge from these...
