Temporal causality and the dynamics of democracy, emigration and real income in Fiji

This study is the first to explore temporal causality between democracy, emigration and real income in Fiji within a multivariate cointegration model. We find three long run relationships between democracy, emigration and real income. In the long run there is evidence that migration and democracy Granger cause real GDP in Fiji; real GDP and democracy Granger cause migration from Fiji and that real GDP and migration Granger cause democracy in Fiji. In the short run we find unidirectional Granger causality running from migration to real GDP and from democracy to real GDP, but neutrality between democracy and migration in the short run. We also extend the analysis to examine the degree of exogeneity of the variables beyond the sample period through considering the decomposition of variance and impulse response functions.

Electricity consumption, employment and real income in Australia evidence from multivariate Granger causality tests

This paper examines the relationship between electricity consumption, employment and real income in Australia within a cointegration and causality framework. We find that electricity consumption, employment and real income are cointegrated and that in the long-run employment and real income Granger cause electricity consumption, while in the short run there is weak unidirectional Granger causality running from income to electricity consumption and from income to employment.

Sustainable living environment for urban low-income households in Malaysia : key factors for maintenance

Urbanisation is predicted to continuously increase every year. Demand for urban shelter will rise and hence this will force governments to act, within their capability, to provide affordable housing in order to maintain social and economic stability. Some industrialized countries have demonstrated full state support from planning and implementation through to continuing maintenance in order to create and sustain a healthy living environment for urban low-in-come households. For developing countries, this might be more difficult. Ensuring adequate maintenance to provide housing quality over the long term is proving even more problematic than simply providing housing. The question is how housing in developing countries can be made sustainable in order to provide a better living environment in the long term. This study focuses on key issues of residential living environments for urban low-cost housing in Malaysia in relation to housing maintenance management. Drawing from extensive primary research and a series of interviews, this exploratory study identifies factors that must be considered by policy makers in order to provide a decent and sustainable living environment for the urban lower-income group. The outcome suggests that current systems of maintenance management - offsetting maintenance to developers or the housing communities themselves, is not working well. The government may need to continue to support low cost housing through maintenance in order to prevent deterioration of accommodation that could become future slums.

Optimal redistribution when educational background matters

Higher education plays an important role in determining individuals lifetime
earnings. In turn, the decision to become educated depends to a large extent on innate ability and on family characteristics, including both family
wealth and educational background. In this paper, we abstract from family
income differences to concentrate on the effects of fiscal policies on the
decision to undertake higher education when the educational background
matters. In a dynamic framework, where successive generations are linked by educational background, we consider a government that uses both linear income taxation and a lump-sum subsidy to education. Conditions for
optimality of each policy are derived. The factors that determine the sign
and magnitude of the tax rate and the subsidy are identified and include
concerns for redistribution, efficiency and the educational externality on
future generations

Applying socio-cultural lenses to childhood obesity prevention among African migrants to high-income western countries : the role of acculturation, parenting and family functioning

Migration from third-world and low-income countries to high-income Western countries presents significant challenges for individuals and families, and for health service providers in the receiving societies. Cultural conflicts related to preferred body size/shape and parenting practices, together with differential inter generational rates and styles of acculturation, can affect nutritional and lifestyle choices and be associated with high rates of childhood obesity. Using African cultures as an example, this paper examines these issues. It concludes that, in designing and implementating obesity prevention programmes, health service providers need to understand these factors and how they play out.

Positron annihilation lifetime spectroscopy as a probe of free volume in plasticized solid polymer electrolytes

A recent report on the correlation between enhanced polymer mobility and ionic conductivity at room temperature in plasticized polyether-urethane solid polymer electrolytes (Forsyth et al.[1]), has prompted the present investigation. Positron annihilation lifetime spectroscopy (PALS) has been used to study the effect of plasticizer addition on the room temperature free volume characteristics of the crosslinked polyether-urethane. The addition of low molecular weight plasticizers to the polyether-urethane results in a constant or decreasing mean free volume cavity radius, as measured by the orthoPositronium lifetime τ₃, and a decreasing relative concentration of free volume cavities as measured by the ortho-Positronium intensity, I₃. It is postulated that the plasticizers interrupt polymer-polymer interactions by occupying the inter- and intra-chain free volume. The plasticizer structure influences the polymerplasticizer interactions which affect inter- and intra-chain separation and hence the free volume of the system. The decrease in polymer-polymer interaction and the increase in polymer-plasticizer interaction in turn influence the glass transition temperature behaviour.

Plasticizer effects in polyether electrolytes studied by positron annihilation lifetime spectroscopy

Positron annihilation lifetime spectroscopy (PALS) has been used to probe the effects on free volume of the addition of either propylene carbonate or tetraglyme to a polyether-based electrolyte. Despite their very different behaviour as observed by NMR and conductivity measurement, the PALS sensitive free volume of the samples changes in a similar way on addition of the two plasticizers. It is concluded that the effect of these plasticizers on conductivity is determined more by their effect on ion-polymer and ion-ion interactions than by their effect on the PALS free volume.

The role of agregate demand and supply shocks in a low-income country : evidence from Bangladesh

This paper explores the relative role of aggregate demand and supply shocks in affecting the output level and inflation rate in a low-income country vulnerable to various economic shocks. The study uses Bangladesh data, and following Cover et al (2006), employs a modification of the Blanchard-Quah (BQ) approach, in which the two shocks are allowed to be correlated. Strong evidence is found for the hypothesis that aggregate demand and supply shocks are interrelated in Bangladesh. For the case in which causality is assumed to be running from demand to supply shocks, it was found that an independent supply shock plays significant role for fluctuations in inflation, which was absent in the standard BQ model. The results suggest that a tightening of monetary policy may lead to an adverse effect on the long-run growth potential and some supply-side policies may be required to supplement contractionary monetary policy in combating inflation in Bangladesh.

Improving our superannuation regime : a post-Henry review look at superannuation taxation, raising superannuation balances and longevity insurance

This paper examines what, if any changes should be made regarding certain aspects of the superannuation system. Specifically, it looks at possible changes to the superannuation tax regime, measures intended at increasing superannuation balances, as well as policies aimed at improving the price and availability of retirement income streams. The recommendations of the final report of the Henry Review on these issues are also critically evaluated. The paper finds that a greater targeting of superannuation tax concessions towards middle and lower income earners would make the system more equitable and achieve other desirable goals such as increasing voluntary savings. Furthermore, the available evidence suggests that the current mandatory contributions rate of 9% is adequate, and a higher contributions rate is likely to have more costs than benefits. On the issue of superannuation income streams, the article finds that whilst taxpayers should continue to be allowed to take their superannuation as a lump sum, policies should be implemented to make lifetime annuities more readily available and better value for money. The Henry Review's recommendations on these issues, with some exceptions, are for the most part sound and based on logic.

Lifetime psychiatric disorders and body composition : a population-based study

Background This study aimed to investigate the relationship between depressive and anxiety disorders and indices of adiposity, including body fat mass and percent body fat, as measured by dual energy X-ray absorptiometry.

Methods In this observational study of 979 randomly-selected women aged 20–93 years, psychiatric history was ascertained using a structured clinical interview (SCID-I/NP). Total body fat was assessed using dual-energy X-ray absorptiometry and weight, height and waist circumference were measured. Medication use and lifestyle factors were self-reported.

Results Those with a lifetime history of depression had increased fat mass (+ 7.4%) and percent body fat (+ 4.3%), as well as greater mean weight (+ 3.3%), waist circumference (+ 2.9%) and BMI (+ 3.5%) after adjustment for age, anxiety, alcohol consumption, physical activity and past smoking. Furthermore, those meeting criteria for a lifetime history of depression had a 1.7-fold increased odds of being overweight or obese (BMI ≥ 25), a 2.0-fold increased odds of being obese (BMI ≥ 30) and a 1.8-fold increased odds of having a waist circumference ≥ 80 cm. These patterns persisted after further adjustment for psychotropic medication use, smoking status and energy intake. No differences in any measures of adiposity were observed among those with anxiety disorders compared to controls.

Limitations There is potential for unrecognised confounding, interpretations are limited to women and a temporal relationship could not be inferred.

Conclusions Depression was associated with greater adiposity. The difference in body fat mass was numerically greater than differences in indirect measures of adiposity, suggesting that the latter may underestimate the extent of adiposity in this population.

A factor-augmented VAR approach : the effect of a rise in the US personal income tax rate on the US and Canada

In this paper a factor-augmented vector autoregressive (FAVAR) model is estimated to characterize the dynamic effects of shocks in the personal income tax rate in the United States on United States and Canadian economies. The representation and the estimate of the FAVAR model is based on Stock and Watson (2005) and the shocks are recovered applying the identification scheme proposed by Bernanke et al. (2005); this method allows impulse response functions to be generated for all the variables in the dataset and provides a description of the domestic and international transmission mechanisms of United States movements in the personal income tax rate. A distinguishing feature of our model is the disaggregation of traded goods sector where imports and exports are disaggregated into 12 and 13 industries, respectively. This provides extra information on the domestic and international transmission mechanism across the two countries. The results show that the FAVAR approach generates a reasonable characterisation of the effects of United States movements in the US personal income tax rate on the United States economy and its transmission to the Canadian economy.
