Why patients attend emergency departments for conditions potentially appropriate for primary care: Reasons given by patients and clinicians differ

Objectives:  To compare reasons identified by clinical staff for potential primary care attendances to the ED with those previously identified by patients.

Patterns of disability and norms of participation through the life course: empirical support for a social model of disability

An attempt has been made in this article to empirically demonstrate the social derivation of disability using quantitative data, framed around the medical model. It would seem that people who are not convinced of the social derivation of disability, are likely to be influenced by findings made in such data. The term ‘social derivation’ is used to encompass both social construction and creation. The approach taken was to focus on one aspect of the social derivation of disability—investigating how the patterns of ‘disabling conditions’ vary over the course of life, specifically the schooling, working and retirement age. The observed patterns are not consistent with a medical model of disability that ignores social factors. Instead, the patterns are linked to social forces, both attitudinal and material. Socially-determined norms of participation, which vary between the life phases, seem to be a key determinant of the observed patterns of disability.

Breaking The Link Between Legal Access To Alcohol And Motor Vehicle Accidents: Evidence From New South Wales.

A large literature has documented significant public health benefits associated with the minimum legal drinking age in the USA, particularly because of the resulting effects on motor vehicle accidents. These benefits form the primary basis for continued efforts to restrict youth access to alcohol. It is important to keep in mind that policymakers have a wide variety of alcohol-control options available to them, and understanding how these policies may complement or substitute for one another can improve policy making moving forward. Towards this end, we propose that investigating the causal effects of the minimum legal drinking age in New South Wales, Australia, provides a particularly informative case study, because Australian states are among the world leaders in their efforts against drunk driving. Using an age-based regression discontinuity design applied to restricted-use data from several sources, we find no evidence that legal access to alcohol has effects on motor vehicle accidents of any type in New South Wales, despite having large effects on drinking and on hospitalizations due to alcohol abuse.

I Was Only Nineteen, 45 Years Ago: What Can we Learn from Australia’s Conscription Lotteries?

The Australian conscription lotteries of 1965-1972 are a unique and underutilised resource for studying the effects of army service and veterans’ programs. Drawing on many data sources and 25 years of related US literature, we present a comprehensive analysis of this natural experiment, examining indicators of health, personal economic outcomes, family outcomes and educational attainment. We discuss the numerous potential mechanisms involved and the limitations of available data.

Are low-skill public sector workers really overpaid? A quasi-differenced panel data analysis

Public–private sectoral wage differentials have been studied extensively using quantile regression techniques. These typically find large public sector premiums at the bottom of the wage distribution. This may imply that low skill workers are ‘overpaid’, prompting concerns over efficiency. We note several other potential explanations for this result and explicitly test whether the premium varies with skill, using Australian data. We use a quasi-differenced Generalized Method of Moments (GMM) panel data model which has not been previously applied to this topic, internationally. Unlike other available methods, this technique identifies sectoral differences in returns to unobserved skill. It also facilitates a decomposition of the wage gap into components explained by differences in returns to all (observed and unobserved) skills and by differences in their stock. We find no evidence to suggest that the premium varies with skill. One interpretation is that the compressed wage profile of the public sector induces the best workers (on unobserved skills) to join the public sector in low wage occupations, vice versa in high wage occupations. We also estimate the average public sector premium to be 6% for women and statistically insignificant (4%) for men.

Foster carers in New South Wales: profile and projections based on ABS census data

Administrative data on foster carers in New South Wales (NSW) are sadly lacking. Based on research commissioned by the NSW Department of Community Services, this paper uses the Australian Bureau of Statistics Census of Population and Housing and other data to provide up-to-date information on the characteristics oj foster carers and the demographic trends that are influencing their numbers. Census data indicate that foster carer families are most likely to contain women aged 35-54 years, not in the labour force. Couples account for two-thirds ofall foster carers, with the majority of those couples also caring for birth children. While single parents account for less than one fifth of all foster carers, they are more likely to foster than couples, either with or without birth children. Higher rates of fostering were found in relatively disadvantaged areas. Projected increases in female labour force participation are expected to contribute to a decline (or to slower growth) in the number of foster carers over the next decade. However, projected increases in sole parent families and couples without children are expected to have the opposite effect. The relative magnitude ofthese effects was not ascertained.

The effect of motherhood on wages and wage growth: evidence for Australia

Labour market theory provides several reasons why mothers are likely to earn lower hourly wages than non-mothers. However, the size of any motherhood penalty is an empirical matter and the evidence for Australia is limited. This paper examines the effect of motherhood on Australian women’s wages and wage growth using a series of panel-data models which control for other relevant factors, both observed and unobserved. Using data from the Household, Income and Labour Dynamics in Australia (HILDA) survey, an unexplained motherhood wage penalty of around four per cent for one child, and eight per cent for two or more children, is found. Further analysis suggests that the wage penalty emerges over time through reduced wage growth, rather than through an immediate wage decline after the birth of a child. This reduction in wage growth is consistent with discrimination but also with a reduction in mothers’ work effort.

Is the Age Gradient in Self-Reported Material Hardship Explained By Resources, Needs, Behaviors, or Reporting Bias?

Older people report much less hardship than younger people in a range of contexts, despite lower incomes. Hardship indicators are increasingly influential, so the source of the gradient has considerable policy implications. We propose a theoretical and empirical strategy to decompose the sources of this relationship. We exploit a unique feature of the Household, Income & Labour Dynamics Australia (HILDA) survey, which collects reports of hardship from all adult household members, facilitating within-couple estimates. The majority of the relationship is explained by observed resources, particularly wealth and home ownership. One third of the relationship is explained by unobserved differences between households, which we interpret as age-related behavioural choices. Reporting error does not appear to contribute to the age gradient.

Changes in Poverty Rates During the Howard Era

This article considers changes in poverty rates under the Howard government. We also make three methodological contributions. We consider the statistical significance of the estimated changes in poverty. We propose a decomposition technique that reconciles the trends in absolute and relative poverty. We also use ‘poverty profiles’, which illustrate sensitivity to alternative poverty lines. We find decreases in absolute poverty and increases in relative poverty, both of which are statistically significant over a range of poverty lines. At a poverty line equal to half of the median income, the increase in relative poverty is statistically significant for all people and borders on significance for children.
