This paper decomposes the redistributive effect on annual and lifetime inequality of a range of taxes and transfers in Australia, using a dynamic cohort lifetime simulation model. The redistributive effect is decomposed into vertical, horizontal and reranking effects. Horizontal inequities in...

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 considers whether an equivalence scale implicit in transfer policy can be inferred from summary measures of reranking (whereby the rank order of pre-tax incomes is different from that of the post-tax distribution). It is conjectured that, if the government has a distributional...

Design of welfare benefits is a tricky business. In this regard, James Meade believed that it is important to avoid excessive distortions to the price of labour. He also recognised that means testing is a useful way of limiting the 'hideously expensive' cost of universal benefits provision; he...

Means testing plays an important role in the UK state pension system. We use a dynamic programming model to consider the effects of a recent policy reform that reduced the marginal tax rates on private income of means tested retirement benefits from 100% to 40%. Our analysis suggests that the...

Estimates for a structural model of savings and labour supply calculated on UK field data support the hypothesis of quasi-hyperbolic discounting. The estimated model indicates that a DC pension encourages increased saving and labour supply prior to pension age, and substantially reduced labour...

This paper describes a structural dynamic microsimulation model of the household that has been developed to explore behavioural responses to pensions policy counterfactuals in Ireland. The model is based upon the life-cycle theory of behaviour, which assumes that individuals make their decisions...
