ItemDo Longer Working Hours Lead to More Workplace Injuries? Evidence from Australian Industry-Level Panel Data( 2004-05)Using Australian industry-level data on weekly hours of work and frequency of new workers' compensation claims for work-related accidents over the 1990s, the relationship between working time and work-related injuries is examined. Results using panel data techniques suggest there is no relationship between working time of full-time workers and workplace safety performance. This finding is in contrast to cross-sectional evidence presented by previous researchers showing significant effects of working time on safety performance. Evidence is found in this study, however, that increased working time of part-time employed persons is associated with a greater rate of workplace injuries.

ItemThe Extent and Consequences of Underemployment in Australia( 2004-08)Underemployment is generally conceived as excess labour supply associated with employed persons; that is, as a situation where employed persons would like to work more hours at prevailing wage rates. Using information collected by the 2001 Household, Income and Labour Dynamics in Australia (HILDA) survey, this study seeks to investigate the extent of underemployment and its effects on outcomes such as income, welfare dependence and subjective well-being. It is found that over one in six employed persons is underemployed, corresponding to a failure to utilise 5 per cent of hours supplied by employed persons. Underemployment is more frequently associated with part-time employment for females, but for males is more frequently associated with full-time employment. Models estimated of the effects of underemployment on outcomes imply that, while unemployment clearly has greater adverse consequences, underemployment is nonetheless associated with significant detrimental effects on the outcomes examined. Negative effects are found for both part-time employed and full-time employed workers who would prefer to work more hours, but effects are greater for underemployed part-time workers, and are particularly large for part-time workers who would like to work full-time. Indeed, for part-time workers seeking full-time employment, effects attributable to underemployment are, for some outcomes, not far short of those attributable to unemployment.

ItemEffects of activity test arrangements on exit from payments: the 9-month intensive review( 2003-09)Since 1996, recipients of unemployment-related welfare payments in Australia have been subject to a review process when their payment spell duration reaches 9 months. This review process is both a monitoring and counselling device: payment recipients are required to provide details of job search activity, while the payments administrator (Centrelink) provides job search advice and assistance. Using Centrelink administrative data over the period 1995 to 2000, this study examines the effects of these reviews on exit from unemployment-related payments. Limitations of the administrative data – in particular, the absence of information on the review process and the nature and precise timing of the review for each recipient – constrain the choice of empirical method. We therefore use duration analysis methods – specifically, estimation of empirical hazards and hazard models – to indirectly infer the impact of the review. Two alternative empirical approaches are taken. The first compares the hazard rate at the 9-month spell duration with hazard rates at 'nearby' spell durations. The second approach exploits a policy change which occurred in March 1996, when the review timing changed from 12 months to 9 months spell duration. For this approach, we compare the 9-month hazard rate in the post-March 1996 period with the 9-month hazard rate in the pre-March 1996 period. We do not find compelling evidence of a substantial or significant effect of the 9-month review using either of the empirical approaches.

ItemEffects of changes in family composition and employment patterns on the distribution of income in Australia: 1981-1982 to 1997-1998(WILEY, 2004-06)We examine income distributions over the last two decades, presenting both non‐parametric kernel density estimates and summary measures. Standard errors of summary measures are also reported to facilitate statistical inference. We find a significant increase in private income inequality, but only a modest increase in disposable income inequality, implying an increase in the inequality‐reducing effects of income taxes and transfers. Using a semi‐parametric procedure developed by DiNardo et al. (1996), we then examine the effects of changes in family characteristics on the distribution of private income, finding that half the increase in inequality is explained by changes in the distribution of employment.

ItemThe changing socio-demographic composition of poverty in Australia: 1982 to 2004(WILEY, 2007-01-01)The extent of income poverty and its socio‐demographic composition are examined using all ABS income surveys conducted over the period 1982 to 2004. There has been some increase in the proportion of the population in poverty, particularly since 1997, but of more note are the substantial changes in the socio‐demographic composition of those in poverty. Compared with the start of the sample period, persons in poverty at the end of the period were much more likely to be older, in families without dependent children, holding post‐school qualifications and/or foreign‐born. In part, these changes reflect broader changes in the composition of the population. However, changes in the risks of poverty associated with different characteristics have also produced large changes in the composition of the poor, and have in some cases counteracted or reversed effects of demographic change. Specifically, the risk of poverty has increased for the elderly, non‐dependent youth, single people, foreign‐born persons and those without post‐school qualifications, and it has decreased for sole parent families and residents of Queensland, the ACT and the Northern Territory.
