This paper explores the characteristics of 238 patents on 94 “inventions” contributed by major multinational innovators to the “Eco-Patent Commons”, which provides royalty-free access to third parties to patented climate change related innovations. By comparing the pledged patents to...

The complexity of integrated assessment models (IAMs) prevents the direct appreciation of the impact of uncertainty on the model predictions. However, for a full understanding and corroboration of model results, analysts might be willing, and ought to identify the model inputs that influence the...

In 2007, the Intergovernmental Panel on Climate Change’s Working Group One, a panel of experts established by the World Meteorological Organization and the United Nations Environment Programme, issued its Fourth Assessment Report. The Report included predictions of dramatic increases in...

We apply the Parry-Small (2005) framework to asses whether the level taxation of motor fuel is broadly appropriate in a group of countries (OECD, BRICs and South Africa) accounting for more than 80 percent of world greenhouse gas (GHG) emissions. This paper deals with emissions from oil...

Climate change must deal with two market failures, global warming and learning by doing in renewable use. The social optimum requires an aggressive renewables subsidy in the near term and a gradually rising carbon tax which falls in long run. As a result, more renewables are used relative to...

Many governments use technology incentives as an important component of their greenhouse gas abatement strategies. These “carrots” are intended to encourage the initial diffusion of new, greenhouse-gas-emissions-reducing technologies, in contrast to carbon taxes and emissions trading which...

Economic models of climate policy (or policies to combat other environmental problems) typically neglect psychological adaptation to changing life circumstances. People may adapt or become more sensitive, to different degrees, to a deteriorated environment. The present paper addresses these...

We analyze a dynamic stochastic general equilibrium model which includes a negative externality that arises from fossil fuels burnings. The carbon released to the atmosphere by electricity producers is the main driver of climate change. We adapt the optimal tax derived by Golosov et al. (2011)...

In a calibrated integrated assessment model we investigate the differential impact of additive and multiplicative damages from climate change for both a socially optimal and a business-as-usual scenario in the market economy within the context of a Ramsey model of economic growth. The sources of...
