On the influence of market structure in modelling the US copper industry

Many of the contemporary models used to describe the behavior of the mineral industries assume a competitive market i.e. one in which market price is equal to marginal production cost. One such recent model of the worldwide copper industry is the MIDAS-II model developed for the Bureau of Mines [3, 4]. This model is used to project production and prices up through the year 2000. The purpose of this paper is to demonstrate the importance of the assumed market structure in the construction of these forecasts. If the market structure of the US copper industry is assumed to be comprised of a few large firms (an oligopoly), then forecasts based upon exactly the same data base differ significantly from the competitive market assumption.     

The role of mitochondria in conserved mechanisms of aging

The European research project MiMage, supported by the European Community's Sixth Framework for Research and Technological Development, focuses on elucidating the role of mitochondria in conserved mechanisms of aging. This Perspective summarizes a selection of talks presented in April 2006 at the second MiMage symposium by members from participating laboratories and invited speakers.     

MiMage: a Pan-European project on the role of mitochondria in aging

The new European research project MiMage, supported by the European Community's Sixth Framework for Research and Technological Development, focuses on elucidating the role of mitochondria in conserved mechanisms of aging. Expertise in different research areas, including biochemistry, cell biology, genetics, molecular biology, and physiology, is provided by twelve research teams from seven European countries, together with one associated team from Canada and the United States. This report provides an introduction to the participating laboratories and the topics that will be addressed within the project, together with a concise report on the first symposium on the role of mitochondria in aging.
