We rank economics departments in the Republic of Ireland according to the number of publications, number of citations, and (successive) h-index of research-active staff. We increase the discriminatory power of the h-index by introducing two ancillary indices. The first (h+) measures the excess...

88 estimates of the marginal costs of carbon dioxide emissions were gathered from 22 published studies and combined to form a probability density function. The uncertainty is strongly rightskewed. If all studies are combined, the mode is $5/tC, the mean $104/tC, and the 95 percentile $446/tC....

We use the new version of the GTAP-W model to analyze the economy-wide impacts of enhanced irrigation efficiency. The new production structure of the model, which introduces a differentiation between rainfed and irrigated crops, allows a better understanding of the use of water resources in...

China is a country with severe water shortages. Water becomes scarcer due to population growth, industrialization and urbanization. Recent studies show that by the next 50 years water resources per capita will go down to around 1700 m3, which is the threshold of severe water scarcity. Especially...

Many regions of the world are facing formidable freshwater scarcity. Although there is substantial scope for economizing on the consumption of water without affecting its service level, the main response to water scarcity has been to increase the supply. To a large extent, this is done by...

A model of carbon dioxide emissions of the USA is presented. The model consists of population, income per capita, economic structure, final and primary energy intensity per sector, primary fuel mix, and emission coefficients. The model is simple enough to be calibrated to observations since...

The Matthew effect has that often-cited papers/authors are cited more often. I use the statistical theory of the growth of firms to test whether the fame of papers and authors indeed exhibits increasing returns to scale, and confirm this hypothesis for the 100 most prolific economists.

A rational, successive g-index is proposed, and applied to economics departments in Ireland. The successive g-index has greater discriminatory power than the successive h-index, and the rational index performs better still. The rational, successive g-index is also more robust to difference in...

This paper applies Tobit models to investigate factors that explain households’ decision-making on whether or not to participate in various activities, using household data collected from two Tanzanian coastal villages (Mlingotini and Nyamanzi). The results indicate that households’ decision...
