Inference in partially non-stationary time series models. Economic theories typically specify the long-run relationship between economic variables. However, researchers usually examine the long-run features of the data by fitting a restrictive class of models using criteria that have only proven useful for short-term forecasting. In this project we consider alternative models and modelling strategies that are appropriate for the study of the long-run. We also develop computer intensive (bootstra ....Inference in partially non-stationary time series models. Economic theories typically specify the long-run relationship between economic variables. However, researchers usually examine the long-run features of the data by fitting a restrictive class of models using criteria that have only proven useful for short-term forecasting. In this project we consider alternative models and modelling strategies that are appropriate for the study of the long-run. We also develop computer intensive (bootstrap) methods, which will provide a much-needed improvement over the existing (asymptotic) methods for making inference about the long-run. Our research will lead to more reliable models for long-term planning in business, industry and government.Read moreRead less
Vector ARMA Models and Macroeconomic Modelling: Some New Methodology and Algorithms. Economic variables are strongly related to each other, as well as being strongly related to their recent history. As a result, good dynamic multivariate models are crucial for effective policy making and forecasting in areas of vital national importance such as monetary and fiscal policy, environmental policy and tourism. Our project advances the frontiers of knowledge in multivariate time series modelling. The ....Vector ARMA Models and Macroeconomic Modelling: Some New Methodology and Algorithms. Economic variables are strongly related to each other, as well as being strongly related to their recent history. As a result, good dynamic multivariate models are crucial for effective policy making and forecasting in areas of vital national importance such as monetary and fiscal policy, environmental policy and tourism. Our project advances the frontiers of knowledge in multivariate time series modelling. The outcome of this project will be immediately useful for macroeconomic policy makers such as the Reserve Bank of Australia and the Treasury, and for industry bodies such as Tourism Australia.

Higher order moment contagion testing: implications of the US subprime mortgage crisis for Australia. Even though crises are usually short lived, the long term implications of changes in asset values may be profound, particularly for superannuation assets. Implications of financial crises are also profound for institutions such as the RBA who change policy to achieve domestic objectives. The understanding of how internationally based financial crises affect Australia is important particularly wh ....Higher order moment contagion testing: implications of the US subprime mortgage crisis for Australia. Even though crises are usually short lived, the long term implications of changes in asset values may be profound, particularly for superannuation assets. Implications of financial crises are also profound for institutions such as the RBA who change policy to achieve domestic objectives. The understanding of how internationally based financial crises affect Australia is important particularly when domestic inflationary pressures would appear to precipitate the need for the RBA to take the opposite policy stance to that prevalent of central banks internationally. This proposal highlights these relationships to provide insights into portfolio allocation decisions and provides information to facilitate well founded decisions by policy makers.Read moreRead less
