Individual and household based aggregate measures of joblessness offer conflicting signals about labour market performance. This paper shows that while individual based measures of joblessness have remained fairly stable over the last 10 years or so and have fallen after highs in the early...

Whilst employment levels in Australia are healthy when compared to those twenty years ago, the available work has become increasingly polarised into either all-work or no-work households. This paper measures the extent of polarisation that has taken place in Australia between 1982 and 1997/98...

This paper summarises a large project involving many studies to evaluate the effects on employment and unemployment in Australia of macroeconomic, wage restraint, taxation and social security systems, and of education and training policies. One set of studies finds that the NAIRU is an uncertain...

The Australian government implemented a series of new private health insurance policies between 1997 and 2000. As a result, the proportion of the population with private health insurance coverage increased by more than 35%. However, this paper finds significant evidence that the policy reform...

Extensive research has shown that few robust results regarding the optimal tax structure are available. Moreover, the stylised models used in optimal tax analyses are not appropriate for practical policy advice. This paper proposes a method of examining optimal marginal income tax reforms using...

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...

This paper examines the role of the tax-free income tax threshold in a complex tax and transfer system consisting of a range of taxes and benefits, each with their own taper rates and thresholds. Considering a range of tax and benefit systems, particularly those having benefit taper rates...

This paper examines the role of the tax-free income tax threshold in a complex tax and transfer system consisting of a range of taxes and benefits, each with their own taper rates and thresholds. Considering a tax and benefit system with benefit taper rates whereby some benefits are received by...

Recent studies have examined tax policy issues using labour supply models characterised by a discretised budget set. Microsimulation modelling using a discrete hours approach is probabilistic. This makes analysis of the distribution of income difficult as even for a small sample with a modest...

The distributional implications of an extreme hypothetical reform of the Australian tax-transfer system are examined using the Melbourne Institute Tax and Transfer Simulator. This simulation model predicts labour supply using a probabilistic discrete hours approach. The analysis of the...
