The one demand Hotelling model fails to explain the observed specialization of nonrenewable resources in specific end-uses. We develop a model with multiple demands and multiple resources and grades. Principles of Ricardian absolute and comparative advantage play an important role in determining...

The one-demand Hotelling model fails to explain the observed specialization of nonrenewable resources. We develop a model with multiple demands and resources to show that specialization of resources according to demand is driven by Ricardian comparative advantage while the order of resource use...

In this article, the ratio of central station electricity to final energy is used as a measure of electrification. It is well known that this ratio tends to increase with gross domestic product. We show that not only is electrification a characteristic of a reference case with economic growth,...

The techniques of probabilistic population forecasting are increasingly being recognised as a profitable means of overcoming many of the limitations of conventional deterministic variant population forecasts. This paper applies these techniques to present the first comprehensive set of...

This paper proposes an extension of the standard parameterised model migration schedule to account for highly age-concentrated student migration. Many age profiles of regional migration are characterised by sudden ‘spiked’ increases in migration intensities in the late teenage...
