This paper studies the cost effectiveness of climate policy if there are technology externalities. For this purpose, we develop a forward-looking CGE model that captures empirical links between CO2 emissions associated with energy use, directed technical change and the economy. We find the...

This paper examines the double dividend hypothesis in the presence of labour income uncertainty. Empirical evidence shows that uncertainty over labour income is particularly significant in developing, while not negligible in developed countries. Under uncertainty, and assuming incomplete capital...

Climate change economics mostly neglects sizeable interactions of carbon pricing with other fiscal policy instruments. Conversely, public finance typically overlooks the effects of future decarbonization efforts when devising instruments for the major goals of fiscal policy. We argue that such a...

This article presents an integrated assessment of climate change, air pollution, and energy security policy. Basis of our analysis is the MERGE model, designed to study the interaction between the global economy, energy use, and the impacts of climate change. For our purposes we expanded MERGE...

The economics of CO2 capture and storage in relation to the possibility of significant leakage of CO2 from geological reservoirs once this greenhouse gas has been stored artificially underground will be among the main determinants of whether CCS can significantly contribute to a deep cut in...

This paper addresses the impact of endogenous technology through research and development (Ramp;D) and learning by doing (LbD) on the timing of environmental policy. We develop two models, the first with Ramp;D and the second with LbD. We study the interaction between environmental taxes and...

Industrial policy has long been criticized as subject to protectionist interests; accordingly, subsidies to domestic producers face disciplines under World Trade Organization agreements, without exceptions for environmental purposes. Now green industrial policy is gaining popularity as...

Globally and locally, government support policies for green goods (like renewable energy) are much more popular internationally than raising the cost of bads (as through carbon taxes). These support policies may encourage downstream consumption (renewable energy deployment) or upstream...

This paper addresses the timing and interdependence between innovation and environmental policy in a model of research and development (Ramp;D). On a first-best path the environmental tax is set at the Pigouvian level, independent of innovation policy. With infinite patent lifetime, the Ramp;D...

This paper analyzes the efficient taxation of oil and capital income in an oil-dependent infinite-lived economy facing perfect capital mobility. Two cases are examined: one with product market imperfections and free tax choice, one with perfect competition and tax restrictions. The optimal tax...
