This paper considers the question under what conditions domestic markets of emission permits would and should merge to become an international market. Emission permits are licenses, and so governments would need to recognize other countries' permits. In a two-county model, we find that it is in...

Trends in the emissions to air of sulphur dioxide, nitrogen oxides, carbon monoxide, volatile organic compounds, and ammonia in Ireland are analysed with a logarithmic mean Divisia index decomposition for the period of 1990‐2009. Emissions fell for four of the five pollutants, with ammonia...

We assess the subsidy for the installation of biomass boilers and wood gasification boilers under the Greener Homes Scheme in Ireland. We find that the (implicit) subsidy per tonne of carbon dioxide avoided varies hugely across households. The current policy costs 17% too much for the emissions...

We estimate the growth rate of the social cost of carbon. This is an indication of the optimal rate of acceleration of greenhouse gas emission reduction policy over time. We find that the social cost of carbon increases by 1.3% to 3.9% per year, with a central estimate of 2.2%. Previous studies...
