The ATO Longitudinal Information Files (ALife): A New Resource for Retirement Policy Research

Polidano, C ; Carter, A ; Chan, M ; Chigavazira, A ; To, H ; Holland, J ; Nguyen, S ; Vu, H ; Wilkins, R (Wiley, 2020-09-14)

The Australian Taxation Office release of annual longitudinally linked individual tax and superannuation records, known as the ATO Longitudinal Information Files (ALife), opens up opportunities for new research. In this study, we provide an overview of ALife, focusing on its use for retirement income research. To this end, we provide the first longitudinal estimates of superannuation outcomes for 1-year birth cohorts. Results show marked increase in disparity of super balances in the lead-up to retirement as those in the top quartile ramp-up their contributions, possibly to take advantage of the favourable tax treatment of superannuation income in retirement years.
Impacts from Delaying Access to Retirement Benefits on Welfare Receipt and Expenditure: Evidence from a Natural Experiment

Oguzoglu, U ; Polidano, C ; Ha, V (John Wiley & Sons, 2020-03)

Governments are responding to fiscal pressures associated with aging populations by increasing the eligibility age for publicly-funded retirement benefits. However, recent studies show large resulting increases in the receipt of disability and unemployment benefits, which raises concern that welfare savings are offset by increased inflows into alternative payments. Using administrative data to examine the impacts of female eligibility age increases in Australia, we find little evidence of this. Instead, most of the increase is because the delay mechanically extends the receipt time of people already on alternative payments. The implication is that fiscal savings are not jeopardized by welfare substitution.
The Effect of Financial Incentives on Labour Supply: Evidence for Lone Parents from Microsimulation and Quasi-Experimental Evaluation

CAI, L ; KALB, G ; TSENG, Y ; VU, THH (Institute for Fiscal Studies, 2008-06)

The aim of this paper is to analyse the work incentive effects of a change in the Australian tax and transfer system on lone parents in July 2000. To evaluate the effect of the total change only, microsimulation can be used; but for a subgroup of lone parents, a few components of this policy change can be analysed through two alternative approaches - microsimulation and quasi-experimental evaluation. Both approaches examine the effects on the probability of employment and on average working hours. The results from microsimulation show that the combined changes introduced in July 2000 - involving reduced withdrawal rates, changed family payments and lower income tax rates - have increased labour supply for lone parents to a moderate extent. The estimated effect on average working hours when using microsimulation is very close to the effect estimated in a quasi-experimental approach using matching techniques to control for alternative influences.
