This paper derives analytical expressions for the revenue elasticity of the Spanish personal income tax system, as applied to tax units and in aggregate. This is complicated by the schedular nature of the system, and the role of central and regional governments, along with the existence of a...

This paper examines the sensitivity of inequality and poverty measures to the adult equivalence scale and the unit of analysis. Comparisons are made using parametric equivalence scales, and income units include individuals, equivalent adults and households. The role of the correlation between...

This paper describes microsimulation modelling in non-technical terms; and it explains what can be achieved with microsimulation modelling in general, and the Melbourne Institute Tax and Transfer Simulator (MITTS) in particular. The focus is on behavioural microsimulation modelling, which takes...

This paper examines the choice of government expenditure on public goods and transfer payments (in the form of pension) in an overlapping generations model, in which individuals live for two ‘periods’ and expenditure is financed on a pay-as-you-go (PAYG) basis. The condition required for...

This paper examines the effects on consumer prices arising from imposing a carbon tax in New Zealand, using information about inter-industry transactions and the use of fossil fuels by industries. The welfare effects of the carbon tax are examined for a range of different household types....

Reductions in carbon dioxide emissions can come from (among other things) changes to the structure of final demands, changes in the use of fossil fuels by industry, and changes to the structure of inter-industry transactions. This paper examines the nature of the least disruptive changes, that...

This paper addresses the need for a measure of the uncertainty that is associated with the results calculated through tax policy behavioural microsimulation modelling. Deriving the analytical measure would be extremely complicated, therefore, a simulated approach is proposed which generates a...

In New Zealand, excise taxes are levied on three commodity groups: alcohol, tobacco and petrol. The 2001 Tax Review, published by the New Zealand Treasury, argued that excises are inequitable and inefficient, and advised that these taxes should be removed and the revenue replaced by raising the...

This paper explores the use of a loglinear tax and transfer function, displaying increasing marginal and average tax rates along with a means-tested transfer payment. The two parameters are a breakeven income threshold, where the average tax rate is zero, and a tax parameter equivalent to the...
