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.

Empirical and Theoretical Coherence of Macroeconometric Models. Variants of the G-Cubed models are used by researchers, governments and international institutions for policy analysis. The need for policy makers to have models with substantial structural detail and a strong theoretical base is paramount for transparency and accountability. The development of simple SVAR models which capture these theoretical underpinnings will provide Australian policy makers with an effective tool for economic a ....Empirical and Theoretical Coherence of Macroeconometric Models. Variants of the G-Cubed models are used by researchers, governments and international institutions for policy analysis. The need for policy makers to have models with substantial structural detail and a strong theoretical base is paramount for transparency and accountability. The development of simple SVAR models which capture these theoretical underpinnings will provide Australian policy makers with an effective tool for economic analysis. It will also provide powerful tools that enable forecasting and detailed policy analysis within the same broad conceptual framework. The emphasis is on international and financial market linkages which encompass key issues facing the Australian economy.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.. It seeks ....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.. It seeks to answer a number of questions that have arisen in recent years over whether the business cycle is becoming longer owing to improved methods of inventory controlRead moreRead less
