Water problems are typically studied at the farm-level, the river–catchment-level or the country-level. About 70% of irrigation water is used for agriculture, and agricultural products are traded internationally. A full understanding of water use is impossible without understanding the...

We estimate carbon dioxide emissions for the 3401 electoral districts of the Republic of Ireland combining data from the Census, the Household Budget Survey, the National Accounts, Environmental Accounts, and the Labour Accounts. The source data is available for many countries, but we are not...

An emission intensity protocol to govern long-term international greenhouse gas emission reduction is proposed. The protocol may also be interpreted as a technology protocol. The protocol consists of three parameters: a graduation income, below which countries have no emission reduction...

One problem in international climate policy is the refusal of large developing countries to accept emission reduction targets. Brazil, China and India together account for about 20% of today's CO₂ emissions. We analyse the case in which there is no international agreement on emission reduction...

We examine the impacts of the EU–US Open Skies agreement on the environment on emissions from the aviation sector. We use the Hamburg Tourism Model of domestic and international tourist numbers and flows, to estimate these impacts. The Open Aviation Area will result in increased...

We use a model of domestic and international tourist numbers and flows to estimate the impact of the EU–US Open Skies agreement that is to take effect in March 2008. The Open Aviation Area will result in increased competition between transatlantic carriers and consequently falls in the...

The Ramsey rule for the consumption rate of discount assumes a transfer of money of a (representative) agent at one point in time to the same agent at another point in time. Climate policy (implicitly) transfers money not just over time but also between agents. I propose three alternative...

Quantile kernel regression is a flexible way to estimate the percentile of a scholar’s quality stratified by a measurable characteristic, without imposing inappropriate assumption about functional form or population distribution. Quantile kernel regression is here applied to identifying the...

We employ Monte Carlo analysis to determine the distribution of returns for various electricity generation technologies. Costs and revenues for each technology are arrived by means of a sophisticated unit commitment and economic dispatch algorithm. The results show that small amounts of coal...

We estimate the gross margin that is earned from the supply of electricity to households in Ireland. Using half hourly electricity demand data, the system marginal price (also called the wholesale price) and the retail price of electricity, we analyse how the gross margin varies across customers...
