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.

How do company announcements affect trading frequency in stocks? This project addresses the question of how financial markets respond to news by investigating how company announcements affect trading patterns in Australian banking stocks. Analysis will be based on new extensions to autoregressive conditional hazard (ACH) models, with research focussing on how to incorporate announcement variables into an ACH framework and how to modify standard ACH analysis to account for simultaneous transactio ....How do company announcements affect trading frequency in stocks? This project addresses the question of how financial markets respond to news by investigating how company announcements affect trading patterns in Australian banking stocks. Analysis will be based on new extensions to autoregressive conditional hazard (ACH) models, with research focussing on how to incorporate announcement variables into an ACH framework and how to modify standard ACH analysis to account for simultaneous transactions, market frictions and spillover effects. The results of this research will assist government and companies in choosing announcement times, aid traders in portfolio adjustment and will lead to a better understanding of the microstructure of Australian stock markets.Read moreRead less

Modelling non-linear price dynamics of primary commodities that are affected by seasonality, significant storage costs, and slow adjustment. Australia's economy relies substantially on exports of commodities. However, recent volatility of commodity prices has created tremendous uncertainties for traders, producers and consumers of those commodities. This adversely affects our national economy through the disruption of agricultural and mining production, and also more broadly impacts on investmen ....Modelling non-linear price dynamics of primary commodities that are affected by seasonality, significant storage costs, and slow adjustment. Australia's economy relies substantially on exports of commodities. However, recent volatility of commodity prices has created tremendous uncertainties for traders, producers and consumers of those commodities. This adversely affects our national economy through the disruption of agricultural and mining production, and also more broadly impacts on investment, employment and gross domestic income. This research will model more accurately the complex dynamics of primary commodity prices and their inter-market linkages, which will allow traders, producers and consumers to better forecast commodity price movements and protect themselves through inventory management, hedging and long-run production planning.Read moreRead less

An econometric investigation of technical analysis as a portfolio selection strategy in Australia. This project will provide an in-depth analysis of the returns of portfolios of Australian equities formed by using technical trading rules. The research will determine whether or not any abnormal returns earned by these means are attributable to firm-specific or market-wide factors. This project represents the first attempt to interpret technical analysis in a portfolio framework and will provide v ....An econometric investigation of technical analysis as a portfolio selection strategy in Australia. This project will provide an in-depth analysis of the returns of portfolios of Australian equities formed by using technical trading rules. The research will determine whether or not any abnormal returns earned by these means are attributable to firm-specific or market-wide factors. This project represents the first attempt to interpret technical analysis in a portfolio framework and will provide valuable information on the informational efficiency of Australian capital markets. As there is currently no single definitive study of technical analysis in Australia, this project will fill a significant void in the current academic literature and provide evidence of great practical relevance to Australian investment practitioners.Read moreRead less

When Markets Fail: A Comparative Assessment of Costs and Benefits of Trade Interruption. Stock exchanges worldwide provide the opportunity to instantaneously and continuously trade securities.

Stock exchanges worldwide provide the opportunity to instantaneously and continuously trade securities. The introduction of automated trading systems has considerably enhanced this opportunity. Surprisingly, exchanges still have (and use) the discretion to occasionally suspend trading in certain stocks. These trading halts are used to prevent a disorderly or uninformed response to pertinent company information releases. Practitioners and academics tend to believe that trading halts do not serve this role well. We propose a new methodology to more accurately measure the costs and benefits of trade suspensions. We compare their impact on different trading systems, and evaluate their intertemporal performance.Read moreRead less
Australia's Resilience to Recession. This project aims to study why Australia differs from its OECD peers in that it has not had a recession for 27 years. It intends to generate knowledge by using economic models to solve 3 puzzles relating to Australia’s success: (i) why did foreign financial market shocks not spill over to the economy?; (ii) how has the resource curse that affects economies with a booming resource sector been avoided?; and (iii) what makes Australia special? Expected outcomes ....Australia's Resilience to Recession. This project aims to study why Australia differs from its OECD peers in that it has not had a recession for 27 years. It intends to generate knowledge by using economic models to solve 3 puzzles relating to Australia’s success: (i) why did foreign financial market shocks not spill over to the economy?; (ii) how has the resource curse that affects economies with a booming resource sector been avoided?; and (iii) what makes Australia special? Expected outcomes include the development of theoretical and empirical models that reflect the unique features of the Australian economy. This should provide significant benefits, including guidance to Australian and international policymakers on macroeconomic policies for resource-rich countries.Read moreRead less
