Sparse matrix methods for computable general equilibrium models of the Johansen class

Abstract: Considers the solution of large systems of linear equations, such as those arising from a large linearized economic model. Recommends (a) that matrix inversion be avoided, in favour of LU methods; and (b) that sparsity in the system be exploited using special computer subroutines. Some examples of time savings are tabulated. Please note: The PDF download of this fairly old paper is an optical scan of indifferent, but legible, quality
