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...

This paper presents a method of computing welfare changes (compensating and equivalent variations) arising from a tax or social security policy change, in the context of behavioural microsimulation modelling where individuals can choose between a limited number of discrete hours of work. The...

This paper focuses on the correlation of labour market outcomes of parents and children and investigates whether education is an important factor in this correlation, allowing for its potential endogeneity. Based on the Household, Income and Labour Dynamics in Australia (HILDA) data, the...

This paper extends the 'top-down' framework, introduced by Robilliard et al. (2001), to link a computable general equilibrium (CGE) model to a microsimulation model. The proposed approach allows the linking of a microsimulation model to a dynamic, and not simply a static, CGE model by enabling...

This paper investigates the persistence over time of living in a jobless household, aiming to disentangle the roles of state dependence and unobserved heterogeneity. In addition, the potential heterogeneity of state dependence is examined through estimation of interaction terms with the lagged...

To date, there has been little data or empirical research on the determinants of doctors’ earnings despite earnings having an important role in influencing the cost of health care, decisions on workforce participation and labour supply. This paper examines the determinants of annual earnings...

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 presents two 'non-welfarist' approaches and one 'welfarist' approach to decompose changes in inequality and social welfare into three components. We distinguish the contributions of population, tax policy and labour supply behavioural effects. As an illustration, we decompose changes...

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...
