Innovation and Climate Change Policy

American Economic Journal: Economic Policy, 2012, vol. 4, issue 4, 125-45

Abstract: This paper examines whether climate change policies will induce innovation in environmentally friendly technologies. The model demonstrates that a tighter emissions cap will reduce the scale of fossil fuel usage and that this will diminish incentives to improve fossil fuel efficiencies. In addition, such policies may stimulate the relative demand for innovations that improve the efficiency of alternative energy but carbon scarcity may diminish innovation incentives overall. Only for technologies that directly abate carbon pollution will there be an unambiguously positive impact on innovation. These results have implications for climate change targets and the design of climate change policy. (JEL O31, Q54, Q55, Q58)
