The performance of the Australian welfare system in a time of neoliberal economic reform

“Neoliberalism”, both as a body of theory and as a set of policies and practices, is commonly seen as unsympathetic, even antagonistic, to the welfare state. In the period from the mid‐1980s to the global financial crisis of 2007–08, Australia underwent very considerable “neoliberal” economic policy reform. What happened to the Australian welfare system and to Australia's socioeconomic egalitarianism in this period? To shed light on that question three kinds of trend are tracked. The first is household taxes and social expenditure in both cash and kind, using fiscal incidence analysis where the main metric is “net benefits”. The second is economic inequality, as measured by the distribution of incomes and wealth. The third is the performance of the labor market, as measured by earned incomes and unemployment rates. The article concludes with an attempt to integrate the evidence collected from these three sources. The general conclusion is that the Australian welfare system did not follow the pessimists' predictions. The welfare system grew in size and redistributive quantum. Wage levels rose strongly, while unemployment rates fell. Overall, income inequality increased to a small extent, though mainly before the full economic reform process was in place, while wealth inequality changed little.     

The potential impact of comparative effectiveness research on U.S. Health Care expenditures

Comparative effectiveness research (CER) has the potential to slow health care spending growth by focusing resources on health interventions that provide the most value. In this article, we discuss issues surrounding CER and its implementation and apply these methods to a salient clinical example: treatment of prostate cancer. Physicians have several options for treating patients recently diagnosed with localized disease, including removal of the prostate (radical prostatectomy), treatment with radioactive seeds (brachytherapy), radiation therapy (IMRT), or—if none of these are pursued—active surveillance. Using a commercial health insurance claims database and after adjustment for comorbid conditions, we estimate that the additional cost of treatment with radical prostatectomy is $7,300, while other alternatives are more expensive—$19,000 for brachytherapy and $46,900 for IMRT. However, a review of the clinical literature uncovers no evidence that justifies the use of these more expensive approaches. These results imply that if patient management strategies were shifted to those supported by CER-based criteria, an estimated $1.7 to $3.0 billion (2009 present value) could be saved each year.     

“Are You Interested,Baby?” Young Infants Exhibit Stable Patterns of Attention During Interaction

The degree to which infants' current actions are influenced by previous action is fundamental to our understanding of early social and cognitive competence. In this study, we found that infant gazing manifested notable temporal dependencies during interaction with mother even when controlling for mother behaviors. The durations of infant gazes at mother's face were positively predicted by the durations of the two previous gazes at mother's face. Similarly, the durations of gazes away from mother's face were positively predicted by the durations of the two previous gazes of the same type. The durations of gazes at and away from mother's face, however, were not predicted by one another. This pattern suggests that infants exhibit distinct and temporally stable levels of interest in social and nonsocial features of the environment. We discuss the implications of these results for parents, for experimental research using looking time measures, and for our understanding of infants' developing communicative abilities.     

A Profile of Pornography Users in Australia: Findings From the Second Australian Study of Health and Relationships

There are societal concerns that looking at pornography has adverse consequences among those exposed. However, looking at sexually explicit material could have educative and relationship benefits. This article identifies factors associated with looking at pornography ever or within the past 12 months for men and women in Australia, and the extent to which reporting an “addiction” to pornography is associated with reported bad effects. Data from the Second Australian Study of Health and Relationships (ASHR2) were used: computer-assisted telephone interviews (CASIs) completed by a representative sample of 9,963 men and 10,131 women aged 16 to 69 years from all Australian states and territories, with an overall participation rate of 66%. Most men (84%) and half of the women (54%) had ever looked at pornographic material. Three-quarters of these men (76%) and more than one-third of these women (41%) had looked at pornographic material in the past year. Very few respondents reported that they were addicted to pornography (men 4%, women 1%), and of those who said they were addicted about half also reported that using pornography had had a bad effect on them. Looking at pornographic material appears to be reasonably common in Australia, with adverse effects reported by a small minority.     

Harvard Crooners: Building Intergenerational Relationships Through Participatory Music Making

The world is rapidly aging, and yet aging is fraught with many difficulties. In particular, the rights of older people to participate fully in cultural life are frequently not met. To help address this issue, we propose an innovative model for intergenerational, participatory music-making between younger people and older people. Specifically, instead of giving traditional, non-participatory performances for older people as is commonly done in nursing homes and other elderly institutions, we advocate for engaging seniors in collective music-making and singing. We believe this kind of collective music-making will better meet the rights of older adults to participate in cultural life and will lead to stronger intergenerational relationships.     

Orthogonality of the mean and error distribution in generalized linear models

We show that the mean-model parameter is always orthogonal to the error distribution in generalized linear models. Thus, the maximum likelihood estimator of the mean-model parameter will be asymptotically efficient regardless of whether the error distribution is known completely, known up to a finite vector of parameters, or left completely unspecified, in which case the likelihood is taken to be an appropriate semiparametric likelihood. Moreover, the maximum likelihood estimator of the mean-model parameter will be asymptotically independent of the maximum likelihood estimator of the error distribution. This generalizes some well-known results for the special cases of normal, gamma, and multinomial regression models, and, perhaps more interestingly, suggests that asymptotically efficient estimation and inferences can always be obtained if the error distribution is non parametrically estimated along with the mean. In contrast, estimation and inferences using misspecified error distributions or variance functions are generally not efficient.
