Recent efforts to endogenize technological change in climate policy models demonstrate the importance of accounting for the opportunity cost of climate R&D investments. Because the social returns to R&D investments are typically higher than the social returns to other types of investment, any...

We evaluate the employment effect of the green part of the largest fiscal stimulus in recent history, the American Recovery and Reinvestment Act (ARRA). Each $1 million of green ARRA created 15 new jobs that emerged especially in the post-ARRA period (2013-2017). We find little evidence of...

Reducing emissions of the greenhouse gases that cause climate change will require dramatic changes in the way that energy is produced and consumed. The cost of technological changes such as alternative energy sources and improved energy efficiency will play a large role in determining the...

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...

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...

The catchword 'green skills' has been common parlance in policy circles for a while, yet there is little systematic empirical research to guide public intervention for meeting the demand for skills that will be needed to operate and develop green technology. The present paper proposes a...

By reducing the costs of environmental protection, technological change is important for promoting green growth. This entails both the creation of new technologies and more widespread deployment of existing green technologies. This paper reviews the literature on environmentally friendly...

R&D is an uncertain activity with highly skewed outcomes. Nonetheless, most recent empirical studies and modeling estimates of the potential of technological change focus on the average returns to research and development (R&D) for a composite technology and contain little or no information...

This paper provides a primer on the economics of environmental innovation. Our intention is not to write a pure review paper, but to also provide an up-to-date textbook treatment on the issue. Thus, we start by defining the marginal costs of both emissions and of emissions abatement. We then...
