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
Effects of Maternal Work, Day Care Use and Other Investments in Children on Child Cognitive Outcomes. Later life outcomes due to investments by individuals and/or society in children is crucial to many countries, including Australia. Appropriate policy responses require reliable and valid estimates of the likely effects of individual investments and policy interventions. Despite many research reports on this topic, almost all do not control for selection bias (eg, high achieving mothers tend to ....Effects of Maternal Work, Day Care Use and Other Investments in Children on Child Cognitive Outcomes. Later life outcomes due to investments by individuals and/or society in children is crucial to many countries, including Australia. Appropriate policy responses require reliable and valid estimates of the likely effects of individual investments and policy interventions. Despite many research reports on this topic, almost all do not control for selection bias (eg, high achieving mothers tend to put children in day care), which is a feature of our work. Thus, our empirical results will have major policy implications, and will suggest ways to obtain similar results for Australian environments. Read moreRead less

The Project focuses on the processes of job creation and destruction in Australia using sophisticated econometric modelling and an innovative mix of data sources. The research outcomes will deliver benefits in the improvement of labour market policy. Special focus will be on the impacts of structural change, trade liberalisation and the role of small business. The research will fill major gaps in the literature by providing new insights into job creation and destruction processes and the consequences for unemployment, at levels of disaggregation and in sectors not previously studied, notably, full-time/part-time; public/private; the service sector; as well as demographic variability.Read moreRead less
Modelling the Choices of Individuals. Individuals make decisions daily and some of these decisions have wide-reaching and long-term consequences, such as choices among housing, public transport, electoral candidates and health care options. The principal aim of this project is to develop reliable and valid ways to model individual level choice processes. Once completed, this will provide insights into ways to aggregate sampled observations when population-level applications are required, and all ....Modelling the Choices of Individuals. Individuals make decisions daily and some of these decisions have wide-reaching and long-term consequences, such as choices among housing, public transport, electoral candidates and health care options. The principal aim of this project is to develop reliable and valid ways to model individual level choice processes. Once completed, this will provide insights into ways to aggregate sampled observations when population-level applications are required, and allow us to compare and test several competing theories of choice behaviour. This will enable us to make contributions to understanding and modelling human decision making in many fields ranging from marketing to medicine.Read moreRead less
How the allocation of children's time affects the stimulation of cognitive and non-cognitive development. In a 2008 Organisation for Economic Co-operation and Development (OECD) report, more than seven percent of Australian children have fewer than 11 books in their family home, Australia ranks in the bottom third of OECD nations for infant mortality and 21st out of 27 for children eating meals with their parents. The Rudd Government is committed to a child-centred approach to family policy. In ....How the allocation of children's time affects the stimulation of cognitive and non-cognitive development. In a 2008 Organisation for Economic Co-operation and Development (OECD) report, more than seven percent of Australian children have fewer than 11 books in their family home, Australia ranks in the bottom third of OECD nations for infant mortality and 21st out of 27 for children eating meals with their parents. The Rudd Government is committed to a child-centred approach to family policy. In this study we investigate the allocation of Australian children's time and its effect on their cognitive and non-cognitive development. Cognitive and non-cognitive development is crucial to the future wellbeing of a child and therefore to the wellbeing of the nation.Read moreRead less
New Procedures for Multiple Testing of Econometric Models. In discipline areas ranging from biological and medicine sciences to economics and commerce, very important decisions are made on the basis of statistical or econometric models. There is usually a high degree of uncertainty about the exact form the model should take and the data available to help decide on the best form of the model is often limited. The new procedures developed in this project will help statisticians and econometricians ....New Procedures for Multiple Testing of Econometric Models. In discipline areas ranging from biological and medicine sciences to economics and commerce, very important decisions are made on the basis of statistical or econometric models. There is usually a high degree of uncertainty about the exact form the model should take and the data available to help decide on the best form of the model is often limited. The new procedures developed in this project will help statisticians and econometricians make better decisions about the best form of their models. Our approach gives a new method of validating an estimated model before it is put to use to make critical decisions.Read moreRead less
Nonparametric estimation of regression models with unknown error distributions. In discipline areas ranging from bioinformatics to economics and commerce, researchers make important decisions based on regression models, where the error density is often unknown. This project will result in a new sampling procedure that aims to choose bandwidth parameters for estimating the regression function and error density in nonparametric regression models.

In discipline areas ranging from bioinformatics to economics and commerce, researchers make important decisions based on regression models, where the error density is often unknown. This project will result in a new sampling procedure that aims to choose bandwidth parameters for estimating the regression function and error density in nonparametric regression models. Our approach is of practical importance and can be used to investigate relationships between variables that are observable in our economy and community. The nation will benefit from the output of this project by having its own experts in the area of proposed research, raising Australia's academic profile in econometrics and statistics.

Estimation and Inference in Weakly Identified Models. Economic and social systems are made up of interacting components leading to complex structures that are difficult to predict and manage. Consequently policy analysis and decision-making must be informed by statistical analysis of data. In many situations the informational content of observations is minimal; examples of such situations are found in the areas of education, health, finance and various aspects of macroeconomic analysis. This pro ....Estimation and Inference in Weakly Identified Models. Economic and social systems are made up of interacting components leading to complex structures that are difficult to predict and manage. Consequently policy analysis and decision-making must be informed by statistical analysis of data. In many situations the informational content of observations is minimal; examples of such situations are found in the areas of education, health, finance and various aspects of macroeconomic analysis. This project aims to develop methods of estimation and inference that make more efficient use of the information available in data. This will lead to more precise statistical analyses, resulting in a clearer understanding of economic and social systems, and better informed policy analysis and decision-making.Read moreRead less
