Multi-gas approaches to climate change policies require a metric establishing equivalences among emissions of various species. Climate scientists and economists have proposed four classes of such metrics and debated their relative merits. We present a unifying framework that clarifies the...

Multi-gas approaches to climate change policies require a metric establishing "equivalences" among emissions of various species. Climate scientists and economists have proposed four classes of such metrics and debated their relative merits. We present a unifying framework that clarifies the...

The Stern Review added balanced growth equivalences (BGE) to the economic climate change research agenda. We first propose rigorous definitions of the BGE for multiple regions and under uncertainty. We show that the change in the BGE is independent of the assumed scenario of per capita income....

In this paper we carry out a meta-analysis of recent studies into the costs of greenhouse gas mitigation policies that aim at the long-term stabilization of these gases in the atmosphere. We find the cost estimates of the studies to be sensitive to the level of the stabilization target, the...

The Stern Review reported a social cost of carbon of over $300/tC, calling for ambitious climate policy. We here conduct a systematic sensitivity analysis of this result on two crucial parameters: the rate of pure time preference, and the rate of risk aversion. We show that the social cost of...

Energy usage and energy efficiency are of increasing concern in Ireland. Regression analyses on a large household micro-dataset reveal that those homes that have more energy-saving features are also likely to have a high ?potential energy use?. Statistically significant dwelling features include...

We estimate a pooled travel model for the destination choice of tourists from the Republic of Ireland in 2006. We distinguish between holidaymakers (further split into travelling with children, elderly, and other), visitors to family, visitors to friends, business travellers and other...
