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...

In the late 1980s and early 1990s, concern over dioxin in both paper products and wastewater led to the development of techniques that reduced the use of chlorine in the pulp industry. Both regulatory and consumer pressure motivated this change. We use patent data to examine the evolution of two...

Within the field of environmental economics, the role of technological change has received much attention. The long-term nature of many environmental problems, such as climate change, makes understanding the evolution of technology an important part of projecting future impacts. Moreover, in...

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...

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...

This paper examines the effect of environmental policies on technological innovation in the specific case of renewable energy. The analysis is conducted using patent data on a panel of 25 countries over the period 1978-2003. It is found that public policy plays a significant role in determining...

Countries who adopted regulation of coal-fired power plants after 1980 generally did so at a much lower level of per-capita income than did early adopters -- poor countries regulated sooner. This phenomenon suggests that pioneering adopters of environmental regulation provide an advantage to...

Ever since Michael Porter proposed that environmental regulations can improve competitiveness, much economic research has examined the potential for such outcomes. Attempts to model Porter hypothesis outcomes in a way consistent with neoclassical economics have focused on things such as...

While the developed world is starting to limit emissions of greenhouse gases, emissions from the developing world are increasing as a result of economic growth. Reducing these emissions while still enabling developing countries to grow requires the use of new technologies. In most cases, these...

This article uses patent citation data to study flows of knowledge across time and across institutions in the field of energy research. Popp [2002, Induced Innovation and Energy Prices. American Economic Review, 92(1), 160-180.] finds that the level of energy-saving research and development...
