[Proposals for the computation of competitive equilibria in the presence of taxation contained in recent joint work by the author are applied to a model of the United Kingdom economy and tax system for the period 1968-1970. Difficulties of model specification and parameterization are also discussed. Results provide indications of efficiency, distributional, and welfare impacts for a number of alternative tax changes.]
