This paper presents an examination of the socially efficient formation of environmental R&D in Cournot duopoly in a setting where a regulator has no precommitment ability for an emission tax. The results reveal that if the environmental damage is slight, alternatively, given severe environmental...

International diffusion of energy-saving technologies has received considerable attention in recent energy and climate economics studies. As a helpful methodological complement to the existing large-scale CGE/IAM–based modelling for energy and climate policy studies, this paper contributes to...

This paper aims at improving the application of the learning curve, a popular tool used for forecasting future costs of renewable technologies in integrated assessment models (IAMs). First, we formally discuss under what assumptions the traditional (OLS) estimates of the learning curve can...

We develop a theoretical model of directed technical change in which clean (zero emissions) and dirty (emissions-intensive) technologies are embodied in long-lived capital. We show how obsolescence costs generated by technological embodiment create inertia in a transition to clean growth....

Myriad policy measures aim to reduce greenhouse gas emissions from the electricity sector, promote generation from renewable sources, and encourage energy conservation. To what extent do innovation and energy efficiency (EE) market failures justify additional interventions when a carbon price is...

We examine the impact of an optimal emissions tax on research and development of emission reducing green technology (E-R&D) in the presence of R&D spillovers. We show that the size and effectiveness of the optimal emissions tax depends on the type of the R&D spillover: input or output spillover....

There is a large consensus that low levels of carbon price cannot provide adequate incentives to invest in cleaner technologies and abate emissions. Since carbon demand and price tend to decrease during recessions, economists and policy makers have proposed different types of price stabilizing...

Climate regulations tend to target energy intensive sectors whose products are widely used in industrial production as intermediate inputs, such as electricity, and the carbon abatement may be partially offset by intermediate input-led leakage. This paper aims to examine the impact of...

This paper evaluates the effects of the lack of regulatory commitment on emission tax applied by the regulator, abatement effort made by the monopoly and social welfare comparing two alternative policy games. The first game assumes that the regulator commits to an ex-ante level of the emission...
