Efficient Estimation of Statistical Models with Many Parameters. Statistical models are used extensively in business, engineering and the sciences to describe the behavior of systems subject to uncertainty. There are often many unknowns in such models and relatively little data to estimate them. The object of the research is to develop methods that make these statistical models practical to use. The research team will apply the methodology to solve problems in economics, finance, marketing and t ....Efficient Estimation of Statistical Models with Many Parameters. Statistical models are used extensively in business, engineering and the sciences to describe the behavior of systems subject to uncertainty. There are often many unknowns in such models and relatively little data to estimate them. The object of the research is to develop methods that make these statistical models practical to use. The research team will apply the methodology to solve problems in economics, finance, marketing and the analysis of gene expression data.

Spatial smoothing of parameters in the models will involve application of hierarchical spatial prior distributions. The resulting methodology wi ....Bayesian estimation of flexible spatial models with applications in medical imaging and econometric modeling. This project aims to develop statistical methodology for estimating flexible highly parameterised Bayesian spatial models. The flexible models examined will include regression, choice and time series models for data that is spatially registered. Spatial smoothing of parameters in the models will involve application of hierarchical spatial prior distributions. The resulting methodology will be applied to the analysis of medical imaging data and to the estimation of spatial econometric models of residential real estate prices. The expected outcomes include developments in the frontier framework of Bayesian computational estimation methodology, improved methods for medical image processing and estimation of high resolution spatial models of residential real estate prices in Australian metropolitan centres.Read moreRead less
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
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 ....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.

Measurement and Sources of Productivity Growth under Imperfect Competition. The relative growth performance of countries using net output will free comparisons from the contentious and differing adjustments made by many statistical agencies in an attempt to take account of quality change in capital goods. Thus, Australia will have a better understanding of its relative performance in terms of growth, and thus be better positioned to make informed policy decisions. In addition, whether producti ....Measurement and Sources of Productivity Growth under Imperfect Competition. The relative growth performance of countries using net output will free comparisons from the contentious and differing adjustments made by many statistical agencies in an attempt to take account of quality change in capital goods. Thus, Australia will have a better understanding of its relative performance in terms of growth, and thus be better positioned to make informed policy decisions. In addition, whether productivity growth is mainly driven by technical progress or returns to scale, and the size of monopolistic markups, has a large bearing on how we view the performance of an economy and its potential for future growth.Read moreRead less
Modelling the Transmission of International Monetary Policy Shocks: Implications for Australian Asset Markets. Three main outcomes of the project are as follows. First, the relative strengths of the transmission mechanisms linking monetary policy and asset markets will be better identified. This will lead to a better understanding of monetary policy thereby enabling the Reserve Bank to achieve its policy goals of inflation operating at or near the target rate, and for currency markets to exhibit ....Modelling the Transmission of International Monetary Policy Shocks: Implications for Australian Asset Markets. Three main outcomes of the project are as follows. First, the relative strengths of the transmission mechanisms linking monetary policy and asset markets will be better identified. This will lead to a better understanding of monetary policy thereby enabling the Reserve Bank to achieve its policy goals of inflation operating at or near the target rate, and for currency markets to exhibit stability. Second, a number of empirical puzzles relating to monetary policy and asset markets in general, that exist in the empirical literature, will be solved. Third, the project will lead to a number of international papers which will add to the international reputation of Australia as a leading research nation.Read moreRead less
Understanding and Modeling Individual Choices in Applied Economics. The fellowship will create a critical mass of researchers in choice modeling theory and methods in areas that Australia needs to sustain economic progress and plan for the future. It will significantly advance knowledge in several major areas: design of health insurance markets; tests for adverse selection in insurance markets; ability of people to plan for retirement (superannuation choices); ability of people to plan and choos ....Understanding and Modeling Individual Choices in Applied Economics. The fellowship will create a critical mass of researchers in choice modeling theory and methods in areas that Australia needs to sustain economic progress and plan for the future. It will significantly advance knowledge in several major areas: design of health insurance markets; tests for adverse selection in insurance markets; ability of people to plan for retirement (superannuation choices); ability of people to plan and choose in dynamic environments; and decisions to adopt new technologies/products in evolving technology markets. The outcome will be new ways to understand and predict choices that can significantly improve practices in business and other organisations.Read moreRead less
Advertising and Drinking: Does it Matter? The Health profession and various community groups have been demanding the government introduce new alcohol advertising policies that aim to reduce the social cost and misery associated with the misuse of alcohol (estimated to cost Australians about $8 billion, cause about 3,300 deaths and 72,000 hospitalisations annually) and to maintain the health and future well-being of Australians. This project will assess the impact of current advertising policies ....Advertising and Drinking: Does it Matter? The Health profession and various community groups have been demanding the government introduce new alcohol advertising policies that aim to reduce the social cost and misery associated with the misuse of alcohol (estimated to cost Australians about $8 billion, cause about 3,300 deaths and 72,000 hospitalisations annually) and to maintain the health and future well-being of Australians. This project will assess the impact of current advertising policies and the impact of a possible ban on alcohol advertising on the level of alcohol consumption in Australia. The results will be useful to the Australian government, the Australian community and the alcohol industry in developing new advertising policies that aim to reduce alcohol consumption.Read moreRead less

This project will provide improved methods to inform Australia's macroeconomic policies and its strategies for economic development by suggesting the most adequate structural macroeconomic model for the Australian economy. Effective macroeconomic policies, in turn, assure stable economic development, smoothes effects of economic cycles and balances inflation, unemployment, the exchange rate and other macroeconomic indicators. All these indicators are closely linked to the welfare of the Australian people and prosperity of the Australian economy. The importance of an accurate macroeconomic analysis is increased in the current condition of inflationary pressures, fiscal challenges, climate change, and world market instabilities.Read moreRead less
Inventories and the Business Cycle in Australia and the U.S. The project looks at the contribution that inventories make to business cycles in Australia and the U.S. It uses recent research by the chief investigator on measuring business cycles in order to explain how the presence of inventories in an economic system might influence activity in that system. It then adapts an existing model in the literature to quantify the role of inventories in the Australian and U.S business cycles..
