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...

In the last three decades, two questions have been central for the Left. Is there a future for electoral socialism and social democracy? And, is it any longer possible to promote a significant redistribution of income in favour of labour? Political and economic events seem to suggest negative...

In the present paper we use the output of multiple expert elicitation surveys on the future cost of key low-carbon technologies and use it as input of three Integrated Assessment models, GCAM, MARKAL_US and WITCH. By means of a large set of simulations we aim to assess the implications of these...

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...

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...

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...

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 a...

We examine the relationship between competition and innovation in an industry where production is polluting and R&D aims to reduce emissions ("green" innovation). We present an n-firm oligopoly where firms compete in quantities and decide their investment in "green" R&D. When environmental...
