Latent variable modelling of discrete choice experiments. Discrete choice experiments and models are used to forecast consumer responses to changes in products policies and programs worldwide. Recent research suggests key model assumptions are violated because error variances covary with observed and unobserved factors. In order to address this, we will model systematic relationships between error variances and observed (eg, prices, survey length) and unobserved (eg, 'convenience', 'reputation') ....Latent variable modelling of discrete choice experiments. Discrete choice experiments and models are used to forecast consumer responses to changes in products policies and programs worldwide. Recent research suggests key model assumptions are violated because error variances covary with observed and unobserved factors. In order to address this, we will model systematic relationships between error variances and observed (eg, prices, survey length) and unobserved (eg, 'convenience', 'reputation') factors to improve model reliability and accuracy. This should lead to more accurate models/forecasts, benefitting business and government, which addresses the national priority of 'frontier technologies, promoting an innovative culture and economy'.Read moreRead less
Exploring Behavioural Responses of Motorists to Exposure-Based Charging Mechanisms. Our continued reliance on cars is estimated to cost the Australian economy around $50 billion per year in accidents, congestion and air pollution. This project delivers a new approach to reduce these externalities, in which charges are levied on drivers based on their accident history, the kilometres driven and the circumstances under which these kilometres are driven. In addition to the safety and congestion ben ....Exploring Behavioural Responses of Motorists to Exposure-Based Charging Mechanisms. Our continued reliance on cars is estimated to cost the Australian economy around $50 billion per year in accidents, congestion and air pollution. This project delivers a new approach to reduce these externalities, in which charges are levied on drivers based on their accident history, the kilometres driven and the circumstances under which these kilometres are driven. In addition to the safety and congestion benefits, the outcomes of the project will be of importance to those charged with raising revenue to support infrastructure maintenance and development, and the insurance industry as a basis for reducing risks in driving and making premiums more equitable.Read moreRead less

The links between policy initiatives, such as private health insurance incentives, and outcomes are often unclear. This project involves a detailed economic and econometric investigation of individual health insurance and health care consumption decisions and their interaction, and the resulting impact on health ....Economic analysis of inter-relationships between private health insurance and health expenditures. Health care services involve a complex mix of private and public funding and provision. The links between policy initiatives, such as private health insurance incentives, and outcomes are often unclear. This project involves a detailed economic and econometric investigation of individual health insurance and health care consumption decisions and their interaction, and the resulting impact on health care utilisation and expenditure across public and private sectors. The significance of the project lies in its use of innovative methods to combine several data sources, and in the potential for the resulting models to predict the impact of future health policy initiatives.

Robust Empirical Analysis of Poverty and Inequality in Australia. The project aims to improve our understanding of economic poverty and inequality in Australia, and contribute new method to the field of distributional analysis. The empirical analysis of consumption poverty and inequality will highlight the critical methodological assumptions underlying our perceptions of poverty, and provide an evaluation of the effectiveness of a range of programs targeted to the poor. The analysis of economic ....Robust Empirical Analysis of Poverty and Inequality in Australia. The project aims to improve our understanding of economic poverty and inequality in Australia, and contribute new method to the field of distributional analysis. The empirical analysis of consumption poverty and inequality will highlight the critical methodological assumptions underlying our perceptions of poverty, and provide an evaluation of the effectiveness of a range of programs targeted to the poor. The analysis of economic inequality in Australia will determine if recent trends are due to increasing globalisation, and whether national programs were effective in ameliorating international influences. This research will ultimately contribute to more effective poverty alleviation and income support programs.Read moreRead less
