A cutting plane method for linear programming is described. This method is an extension of Atkinson and Vaidya’s algorithm, and uses the central trajectory. The logarithmic barrier function is used explicitly, motivated partly by the successful implementation of such algorithms. This makes it possible to maintain primal and dual iterates, thus allowing termination at will, instead of having to ...

This paper develops methods for evaluating distributional impacts of alternative environmental policies across demographic groups. The income inequality literature provides a natural methodological toolbox for comparing distributions of environmental outcomes. We show that the most commonly used inequality indexes, such as the Atkinson index, have theoretical properties that make them inappropr...

Ian Atkinson was one of the most versatile ecologists ever to work on our shores, an original thinker and true allrounder whose broad scope covered plants, animals, soils. A generalist old school rather than a narrowly focussed specialist, his career notable for collaboration with experts in variety fields lasting contributions vegetation mapping, soil volcanic succession, introduced rodent eco...

In this paper we report on the design and analysis of a multilevel method for the solution of the OrnsteinZernike Equations and related systems of integro-algebraic equations. Our approach is based on an extension of the Atkinson-Brakhage method, with Newton-GMRES used as the coarse mesh solver. We report on several numerical experiments to illustrate the effectiveness of the method.

The paper provides an extension and a new proof of Deaton’s theorem on the undesirability of nonuniform excise taxation when income taxes are a¢ ne and preferences over consumption goods are separable from labour-leisure choices, homothetic, and identical across agents.

A weak canonical form is derived for vector spaces of m x n matrices all of rank at most r. This shows that the structure of such spaces is controlled by the structure of an associated 'primitive' space. In the case of primitive spaces it is shown that m and n are bounded by functions of r and that these bounds are tight. 1980 Mathematics subject classification (Amer. Math. Soc.): 15 A 30, 15 A...
