Does Australian Corporate Taxation Matter? On a GDP-weighted basis the average OECD corporate rate has fallen from 44 percent in 1985 to 31 percent in 2004. Australia operates a flat thirty percent corporate tax rate and this compares well with the current OECD average. Yet, the Business Council of Australia argues that the Australian corporate tax rate is 'uncompetitive'. Certainly, the corporate tax burden (i.e. corporate tax revenue as a proportion of GDP) is very high in Australia, the thi ....Does Australian Corporate Taxation Matter? On a GDP-weighted basis the average OECD corporate rate has fallen from 44 percent in 1985 to 31 percent in 2004. Australia operates a flat thirty percent corporate tax rate and this compares well with the current OECD average. Yet, the Business Council of Australia argues that the Australian corporate tax rate is 'uncompetitive'. Certainly, the corporate tax burden (i.e. corporate tax revenue as a proportion of GDP) is very high in Australia, the third highest in the OECD, and the highest in the Asia-Pacific region. This project will evaluate the extent that the corporate tax burden is a hinderance to Australian firms and economic behaviour. Read moreRead less
Effects on Labour Supply, Savings and Welfare of the July 2007 Policy Changes to Superannuation and the Age Pension. This proposal's central question falls within the priority goal of 'Strengthening Australia's social and economic fabric'. Understanding the effects of alternative superannuation tax arrangements is crucial in view of concerns regarding aggregate private savings and labour force participation in an ageing economy. Low savings or participation could have implications for sustained ....Effects on Labour Supply, Savings and Welfare of the July 2007 Policy Changes to Superannuation and the Age Pension. This proposal's central question falls within the priority goal of 'Strengthening Australia's social and economic fabric'. Understanding the effects of alternative superannuation tax arrangements is crucial in view of concerns regarding aggregate private savings and labour force participation in an ageing economy. Low savings or participation could have implications for sustained economic growth. This project's outcomes will provide an indication of the potential effects of policies on labour supply and savings. After further modifications, the model developed in this project can also address other questions in the context of life-cycle decisions under uncertainty, such as labour supply, fertility or health.Read moreRead less
Hydrological changes in Australia and the South Pacific. This project plans to use stalagmites from the South–West Pacific to generate continuous rainfall records for the last 2000 years. Stalagmites contain uncorrupted data that are not available in other archives, and provide unparalleled accurate chronologies. The spatial and temporal variations of the data may highlight the interplay of climate drivers, such as El Niño Southern Oscillation, and how they change the distribution of rainfall in ....Hydrological changes in Australia and the South Pacific. This project plans to use stalagmites from the South–West Pacific to generate continuous rainfall records for the last 2000 years. Stalagmites contain uncorrupted data that are not available in other archives, and provide unparalleled accurate chronologies. The spatial and temporal variations of the data may highlight the interplay of climate drivers, such as El Niño Southern Oscillation, and how they change the distribution of rainfall in the Pacific. This knowledge would increase our scientific understanding and enable better predictions of the recurrence of droughts and wet events in Australia.Read moreRead less
Reconstructing changes in atmospheric circulation over the mid-latitudes of the Southern Hemisphere during the past 3000 years. The climate of the mid-latitudes of the southern hemisphere is of global significance and yet past changes have proved difficult to reconstruct due to the dearth of records. Working across the Southern Ocean region using tree rings, lake sediments and ice cores, the project will produce the first comprehensive reconstruction spanning the last 3000 years.
Bayesian Inference for Welfare Comparisons of Income Inequality and Poverty. The major expected outcome of this research is an array of techniques for making welfare comparisons involving income inequality and poverty within a framework of Bayesian inference. Various applications of the techniques are expected to yield useful information on inequality comparisons over time and space and on changes in the level of poverty. Given that reduction in levels of inequality and poverty is a matter of ma ....Bayesian Inference for Welfare Comparisons of Income Inequality and Poverty. The major expected outcome of this research is an array of techniques for making welfare comparisons involving income inequality and poverty within a framework of Bayesian inference. Various applications of the techniques are expected to yield useful information on inequality comparisons over time and space and on changes in the level of poverty. Given that reduction in levels of inequality and poverty is a matter of major concern, the development of suitable measurement techniques has immense potential for national benefit. In addition, the project will serve as a vehicle for training two PhD students, and hence will contribute to the small pool of highly trained econometricians with expertise in measuring income inequality.Read moreRead less
Understanding the Saving Behaviour of Australian Households: Private Retirement Provision and the Policy of Forced Saving. The outcomes from the research on Australian retirement saving behaviour will generate a range of national benefits. First, the collaboration of researchers across institutions, and internationally, will enhance and promote Australian research skills.

The outcomes from the research on Australian retirement saving behaviour will generate a range of national benefits. First, the collaboration of researchers across institutions, and internationally, will enhance and promote Australian research skills. Second, Australian research will be will be placed at the forefront of an important, international field. Third, the research will make fundamental contributions to the evidence base for the design of public policies to ensure Australians have access to adequate resources in retirement. This is an urgent public policy concern due to the rapid ageing of the Australian population: the fraction aged over 65 years is forecast to double from 10% to 20% over the next 40 years.Read moreRead less
Relative income, social preferences, and charitable giving: An experimental analysis. Understanding people's incentives to give to others (i.e., what motivates private donations) is important in regulating social interactions, achieving fair outcomes, and designing optimal responses to natural disasters like floods and bushfires. Australia's social and economic fabric is strengthened by good public polices relating to redistribution and taxation. The cross-cultural aspect of our study will incre ....Relative income, social preferences, and charitable giving: An experimental analysis. Understanding people's incentives to give to others (i.e., what motivates private donations) is important in regulating social interactions, achieving fair outcomes, and designing optimal responses to natural disasters like floods and bushfires. Australia's social and economic fabric is strengthened by good public polices relating to redistribution and taxation. The cross-cultural aspect of our study will increase awareness about differing beliefs across countries about the determinants of income and how policy makers can use this information to design appropriate policies to help people in need. This research project will also increase the level of academic interactions between Australian and foreign universities.Read moreRead less
The effects of the tax and social security system on labour supply and social welfare. This research will provide independent assessment of the work-incentive effects of government policies in the area of income tax, social security and childcare costs. Capacity constraints may threaten sustained economic growth in Australia. Understanding and supporting the drivers of work force participation is stated in the National Research Priorities as being vital. In addition to the empirical results, the ....The effects of the tax and social security system on labour supply and social welfare. This research will provide independent assessment of the work-incentive effects of government policies in the area of income tax, social security and childcare costs. Capacity constraints may threaten sustained economic growth in Australia. Understanding and supporting the drivers of work force participation is stated in the National Research Priorities as being vital. In addition to the empirical results, the project provides a set of tools that can be used to evaluate new policies with respect to the effects on labour supply, income distribution and social welfare. This will provide timely and independent evidence on which to evaluate new policies and therefore increase the quality of the debate on tax and social security policy.Read moreRead less
The Governance of Defiance. Defiance is a threat to social order. For this reason sanctioning institutions are in place to punish the defiant through legal, financial and sometimes physical means. The institutional rationale is that, at worst defiance will be silenced and at best, compliance will take its place. Increasingly, adverse and unexpected consequences of dealing with defiance in this way have been exposed. To be accountable for their actions, therefore, authorities have begun to develo ....The Governance of Defiance. Defiance is a threat to social order. For this reason sanctioning institutions are in place to punish the defiant through legal, financial and sometimes physical means. The institutional rationale is that, at worst defiance will be silenced and at best, compliance will take its place. Increasingly, adverse and unexpected consequences of dealing with defiance in this way have been exposed. To be accountable for their actions, therefore, authorities have begun to develop more responsive and deliberative systems. But they also need to know how to read defiance. When is defiance an inappropriate response to a more than reasonable request? And when is defiance a reflection of institutional failure? This project can inform such decision making.Read moreRead less
