The Paternity of the Price-Quality "Value Map"

In the literature on firm strategy and product differentiation, consumer price-quality trade-offs are sometimes represented using consumer “value maps”. These involve the geometric representation of indifferent price and quality combinations as points along curves that are concave to the “quality” axis. In this paper, it is shown that the value map for price-quality tradeoffs may be derived from a Hicksian compensated demand curve for product quality. The paper provides the theoretical link between analytical methods employed in the existing literature on firm strategy and competitive advantage with the broader body of economic analysis

Equity of health care financing in Iran

This study presents the rst analyses of the equity of health care financing in Iran. Kakwani Progressivity Indices (KPIs) and concentration indices (CIs) are estimated using ten national household expenditure surveys, which were conducted in Iran from 1995/96 to 2004/05. The indices are used to analyze the progressivity of two sources of health care financing: health insurance premium payments and consumer co-payments (and the sum of these), for Iran as a whole, and for rural and urban areas of Iran, separately. The results suggest that health insurance premium payments became more progressive over the study period; however the KPIs for consumer co-payments suggest that these are still mildly regressive or slightly progressive, depending upon whether household income or expenditure data are used to generate the indices. Interestingly, the Urban Inpatient Insurance Scheme (UIIS), which was introduced by the Iranian government in 2000 to extend insurance to uninsured urban dwellers, appears to have had a regressive impact on health care nancing, which is contrary to expectations. This result sounds a cautionary note about the potential for public programs to crowd out private sector, charitable activity, which was prevalent in Iran prior to the introduction of the UIIS.Equity, Health care nancing, Kakwani progressivity index, Iran

Does maternity leave affect child health? Evidence from parental leave in Australia survey

One of the arguments that is advanced in support of paid maternity leave (PML) policies is that the mother’s time away from work, around childbirth, is expected to improve maternal health and child health and development. However evidence on these links is scarce and, until recently, little was known about the link, if any, between child health and maternity leave. Moreover, the limited literature that does exist tends to use aggregate data (i.e., an “ecological design”) to test the hypotheses that maternity leave affects maternal and child health. Evidence from micro-level data is rare because of the unavailability of such data on household level. We employ such data from the Parental Leave in Australia Survey (PLAS), which is a nested survey of the Longitudinal Study of Australian Children (LSAC), to examine the impacts of maternity leave on child health. Using the PLAS and the first two waves of the LSAC we find that maternity leave, as measured by the duration of paid maternity leave (PML) and other forms of leave around childbirth, have strong and statistically significant effects on: child health, the decision to breastfeed, the duration of breastfeeding, and the probability that child immunisations are up-to-date. Our results show that mothers who take maternity leave are more likely to breastfeed their children and also that longer-term maternity leave is associated with an increase in the duration of breastfeeding. Our results also confirm that both mothers’ PML and fathers’ paid paternity leave (PPL) have statistically significant and positive effects on general health status of children. We also find that, in most specifications, the effects of PML are significant if the duration of leave is at least 6 weeks. PML is also significantly associated with a lower probability of some childhood chronic conditions such as asthma and bronchiolitis, but the effects of PPL on these conditions is ambiguous

Child Health and the Income Gradient: Evidence from Australia

The positive relationship between household income and child health is well documented in the child health literature but the precise mechanisms via which income generates better health and whether the income gradient is increasing in child age are not well understood. This paper presents new Australian evidence on the child health-income gradient. We use data from the Longitudinal Survey of Australian (LSAC), which involved two waves of data collection for children born between March 2003 and February 2004 (B-Cohort), and between March 1999 and February 2000 (K-Cohort). This data set allows us to test the robustness of some of the findings of the influential studies of Case et al. (2002) and J.Currie and Stabile (2003), and a recent study by A.Currie et al. (2007) , using a sample of Australian children. The richness of the LSAC data set also allows us to conduct further exploration of the determinants of child health. Our results reveal an increasing income gradient by child age using similar covariates to Case et al. (2002). However, the income gradient disappears if we include a rich set of controls. Our results indicate that parental health and, in particular, the mother's health plays a significant role, reducing the income coefficient to zero. Thus, our results for Australian children are similar to those produced by Propper et al. (2007) on their British child cohort. We also find some evidence that higher incomes have a protective effect when health shocks do arise: for several chronic conditions, children from higher-income households are less likely to be reported as being in poor health than children from lower-income households who have the same chronic conditions. The latter result is similar to some recent findings by Condliffe and Link (2008) on a sample of US children.Child health, Income gradient, Parental health, Nutrition, Panel data, Australia

The dynamics of informal care provision in an Australian household panel survey: Previous work characteristics and future care provision

This study contributes to a small literature on the dynamics of informal care by examining the informal care provision choices of working age Australians. We focus on the impact of previous work characteristics (including work security and flexibility) on subsequent care provision decisions and distinguish between care that is provided to people who cohabit and people who reside elsewhere, as well as between the provision of care as the primary caregiver, or in a secondary caring role. Our dynamic framework of informal care provision accounts for state-dependence, unobserved heterogeneity and initial conditions. For both males and females, we find the existence of positive state-dependence in all care states in both the short- and medium-term. Furthermore, the inertia in care provision appears to be stronger for more intensive care. We also find previous employment status has a significant deterrent effect on current care provision decisions. The effects on employment, however, differ according to the type of previous work, the type of care currently provided, and the gender of the caregiver. We also find that workers with perceptions of greater job security are nevertheless less likely to provide subsequent care. Our results also suggest that workers’ perceptions about work flexibility and their stated overall satisfaction with work actually have no impact on their subsequent decisions to provide care in any capacity

Cost-sharing in health insurance and its impact in a developing country– Evidence from a quasi-natural experiment

Though the impact of cost-sharing on health care demand is well documented in developed countries, evidence from developing countries is rare. This paper’s contribution is to analyse the impact of increasing coinsurance in a developing nation -Vietnam – by exploiting a quasi-natural experiment in that country. In 2007, the Vietnam government reintroduced a 20 percent coinsurance for individuals who hold voluntary health insurance policies. As individuals with compulsory health insurance were exempt from this re-imposition of coinsurance, this policy change may be regarded as a quasi-natural experiment. To exploit this change, we use a difference-in-difference approach to examine whether the increase in coinsurance effectively reduced the demand for health care services among those affected. We find it has no statistically significant effect on the quantity of health care demanded. We however find that those who were under 18 or in low income households reduced their health care use after the increase in coinsurance. These findings hold – at least in the short-run, with a variety of different outcomes and estimators

The CKD.QLD data linkage framework: chronic kidney disease and health services utilisation in Queensland, Australia

Chronic kidney disease (CKD) is one of the most common chronic diseases in the western world. In Australia, around 1.7 million Australians aged 18 years and over (about one in ten) have indicators of CKD, and 1.8 million hospitalisations were associated with CKD in 2017–18. There is currently very little understanding of the impact of CKD on health service utilisation and costs. Understanding the disease pathways of CKD and its effects on service utilisation and patient outcomes is essential to predicting the course of the disease in the future, its effects on health services utilisation and capacity to better manage the burden of premature deaths or the need for dialysis that results from CKD. We describe the establishment of a data linkage framework to study hospital admissions of CKD patients in the public renal services in the Australian state of Queensland, and its potential to advance understanding of their course and outcomes. Seven years of retrospective data (2011–2018) on hospital-based health services utilisation were provided by Queensland Health for all 7,341 patients who enrolled in the CKD.QLD Registry up to Jan 2019. The data were supplied from three datasets: the Queensland Hospital Admitted Patient Data Collection, the Queensland Registrar General deaths, and the Activity Based Funding Model Output data. In addition, data were supplied from two cohorts of de-identified patients admitted to hospital in the same interval (22,023 patients each), who were not in the CKD.QLD Registry, the first with CKD and the second without CKD as indicated by International Classification of Diseases and Related Health Problems, Tenth Revision, Australian Modification. The comprehensive and multifaceted data via the data linkage will enable us to identify opportunities for efficiencies in management of patients with CKD and for interventions that improve their outcomes
