This paper has two main goals. The first is to study the links between the “new” economic theories, this is, the “new” trade theory, the “new” growth theory and the “new” economic geography. These are three apparently distinct strands of economics, yet they have a common motivation: the role of increasing returns and the consequent market structure (imperfect/monopolistic competition). The seco...

The minute-by-minute move of the Hang Seng Index (HSI) data over a four-year period is analysed and shown to possess similar statistical features as those of other markets. Based on a mathematical theorem [S. B. Pope and E. S. C. Ching, Phys. Fluids A 5, 1529 (1993)], we derive an analytic form for the probability distribution function (PDF) of index moves from fitted functional forms of certai...

Integrated catchment policies are widely used to manage natural resources in Australian catchments. Decision support tools available to aid integrated catchment management are often limited in their integration of environmental processes with socio-economic systems. Fully integrated models are required to support assessments of the environmental and economic trade-offs of catchment management c...

The first is based upon the seminal work of Nobel Prize winner Larry Klein in his 1947 paper. This has two basic components. First, an essentially Keynesian system of macro-theoretical relationships. Second, fitting curves (planes) through empirical macrodata using econometric (statistical) techniques to estimate parameters for these theoretical relationships. Over the past 60 years, the models...

Attempting to successfully and accurately predict thefinancial market has long attracted the interests and attention ofeconomists, bankers, mathematicians and scientists alike. Thefinancial markets form the bedrock of any economy. There are alarge number of factors and parameters that influence thedirection, volume, price and flow of traded stocks. This coupledwith the m...

The standard socio-economic model (SSSM) postulates very considerable cognitive powers on the part of its agents. They are able to gather all relevant information in any given situation, and to take the optimal decision on the basis of it, given their tastes and preferences. This behavioural rule is postulated to be universal. The concept of bounded rationality relaxes this somewhat, by permitt...

We present a new model for climate system analysis, called CLIMBER-2 (for CLIMate and BiosphERe, level 2). This model fills the current gap between simple, highly parameterized climate models and computationally expensive coupled models of global atmospheric and oceanic circulation. We outline the basic assumptions implicit in CLIMBER-2 and we present examples of climate system analysis includi...
