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...

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...

This article explores the relationship between the concept of uncertainty in information seeking, within a model of the problem-solving process proposed by Wilson (1999a) and variables derived from other models and from the work of Ellis and Kuhlthau. The research has involved longitudinal data...

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...

The variability of demographic trends at the subnational scale, particularly internal and international migration, renders subnational population forecasting more difficult than at the national scale. Illustrating the uncertainty of the demographic future for subnational regions is therefore a...

This paper reports on the application of a probabilistic forecasting framework to Statistics New Zealand’s 2004-based national population projections. The assumptions of the Series 5 projections (the middle series)were set as the medians of the fertility, mortality and net migration predictive...
