This paper provides a unified framework in which to examine income and consumption tax revenue elasticities. In addition, new results are established in relation to consumption taxes. These results help to provide a better understanding of the determinants of the revenue responsiveness...

This paper decomposes the redistributive effect of indirect taxation into vertical, horizontal inequity and reranking effects. The latter two effects arise because households with the same total expenditure have different patterns. The pre-and post-GST structures in Australia are examined. The...

This paper provides new estimates of the revenue elasticity of income taxes in the UK over the period 1989-2000. Observed changes in these elasticities are decomposed into changes due to inflation, real income growth, changes in fiscal structure, and changes in the dispersion of incomes in the...

This paper presents an empirical analysis of the welfare effects of several indirect tax reforms in Australia. The welfare changes are measured in terms of equivalent variations and equivalent incomes, using estimates of the linear expenditure system for each of a range of income groups. The...

This paper examines the Gini-based method of decomposing the redistributive effect of taxation into vertical, horizontal, and reranking components. The consequences of different bandwidth choices, used to identify close-equals groups to estimate the horizontal effect, are discussed. Two opposing...

This paper discusses some of the issues raised by comparisons involving different time periods and population groups. It does not examine the effects of using alternative accounting periods for tax assessment purposes, but considers the possible effects on inequality and progressivity of...

This paper examines methods used to evaluate welfare effects of tax changes, with emphasis on the measurement problems involved. Welfare changes and excess burdens are defined, along with approximations. Aggregate measures, using a social welfare function, are examined. A special case of income...

This paper examines the question of the extent to which redistribution can be achieved using a structure of consumption taxes differential rates and exemptions. A local measure of progression, that of liability progression (equivalent to the revenue elasticity) is examined. Results are obtained...

This paper tests a version of Barro's tax smoothing hypothesis using Australian data for the period 1964/65 to 194/95. The model assumes intertemporal optimisation by a government ssking to minimise the distortionary effects of tax collection.
