Optimism, Pessimism and Confidence - Their economic impacts. When modelling uncertainty, economists typically assume people utilise well-behaved and precise probabilities. As most people have only the vaguest conception of chances of terrorist acts, of contracting SARS, or of extreme market volatility, this limits usefulness of the standard model in predicting or guiding choice. This project aims to incorporate a richer set of attitudes about uncertainty into economic theory, including impreci ....Optimism, Pessimism and Confidence - Their economic impacts. When modelling uncertainty, economists typically assume people utilise well-behaved and precise probabilities. As most people have only the vaguest conception of chances of terrorist acts, of contracting SARS, or of extreme market volatility, this limits usefulness of the standard model in predicting or guiding choice. This project aims to incorporate a richer set of attitudes about uncertainty into economic theory, including imprecise estimates of chance, optimistic (or pessimistic) bias, and relative confidence. This will enable more rigorous analysis of topics like irrational exuberance (panic), consumer stampedes, and (in)tolerance of risk, thereby improving the measurement of benefits and costs of related actions or policies.Read moreRead less
A Principled Approach to Computer Simulation of Dynamic General Equilibrium Macroeconomic Models. In the last two decades a new generation of computer-intensive
modeling techniques has risen to prominence in macroeconomics. These
methods have broad policy applications, from public finance and
reserve bank operation to analysis of long-run productivity growth,
taxation reform, unemployment, international trade policy and natural
resource conservation. The size and complexity of these model ....A Principled Approach to Computer Simulation of Dynamic General Equilibrium Macroeconomic Models. In the last two decades a new generation of computer-intensive
modeling techniques has risen to prominence in macroeconomics. These
methods have broad policy applications, from public finance and
reserve bank operation to analysis of long-run productivity growth,
taxation reform, unemployment, international trade policy and natural
resource conservation. The size and complexity of these models means
that even computer-based techniques will rely for the foreseeable
future on efficient program design to solve them. The project will
construct a comprehensive set of solution techniques and software for
this class of macroeconomic models, including detailed mathematical
analysis on accuracy of model output.Read moreRead less
Heterogeneity, Wage Inequality, Unemployment, and Economic Growth. This project would provide the first internally consistent theory of wage inequality, unemployment and economic growth - and the roles that government policy variables play in determining them. It would use and extend frontier developments in theory, and identify the settings of policy variables (unemployment insurance, tax structures, education policies) that maximise social welfare, given that governments must satisfy their bud ....Heterogeneity, Wage Inequality, Unemployment, and Economic Growth. This project would provide the first internally consistent theory of wage inequality, unemployment and economic growth - and the roles that government policy variables play in determining them. It would use and extend frontier developments in theory, and identify the settings of policy variables (unemployment insurance, tax structures, education policies) that maximise social welfare, given that governments must satisfy their budget constraints. It also aims to uncover the relationship between the innate abilities of workers and their education choices - and the consequences for macro economies and public policy.Read moreRead less
Understanding the Effects of News Shocks on Macroeconomic Fluctuations. There are significant potential benefits for Australia. First, it could lead to more effective policymaking, with an understanding of how policy in one branch of the government can affect other sectors that have not been considered before. For example, changes in fiscal policy can affect not just growth, but also unemployment, inflation, and the income distribution. Second, this project will make a contribution to the resear ....Understanding the Effects of News Shocks on Macroeconomic Fluctuations. There are significant potential benefits for Australia. First, it could lead to more effective policymaking, with an understanding of how policy in one branch of the government can affect other sectors that have not been considered before. For example, changes in fiscal policy can affect not just growth, but also unemployment, inflation, and the income distribution. Second, this project will make a contribution to the research training of new macroeconomists in Australia: we will train three PhD students in the very latest methods. We also will organize a conference and bring the very top economists in the world to work with researchers here, and to consider issues surrounding the Australian economy. Read moreRead less
Noisy Parity Relationships in International Macroeconomic Models. Macroeconomic models of the Australian economy play a key role in the design of monetary and fiscal policy. Policymakers use these models either implicitly or explicitly, and usually begin to learn about them in principles courses. Parity relationships are foundation elements of these models, and have powerful implications for our understanding of macroeconomic dynamics. Classical statistical tests may have falsely led to an unhea ....Noisy Parity Relationships in International Macroeconomic Models. Macroeconomic models of the Australian economy play a key role in the design of monetary and fiscal policy. Policymakers use these models either implicitly or explicitly, and usually begin to learn about them in principles courses. Parity relationships are foundation elements of these models, and have powerful implications for our understanding of macroeconomic dynamics. Classical statistical tests may have falsely led to an unhealthy agnosticism regarding many of these relationships. This research will bring more appropriate statistical techniques to bear upon the problem, and if successful will restore confidence in decision-making processes and the relevance and applicability of macroeconomic models.

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
Time-consistent macroeconomic policy in nonlinear models. Efforts to use fiscal policy for macro-stabilisation have led to elevated debt levels and possible default in many countries. This project examines the appropriate design of fiscal policy and its implications for debt over the business cycle.
Monetary and Fiscal Policy under Imperfect Knowledge. This project lays out an agenda exploring the consequences of imperfect knowledge for macroeconomic dynamics and stabilisation policy. Learning dynamics are central to understanding aggregate fluctuations in periods during which agents have limited information about their environment, as has been the case during and after the Global Financial Crisis. The agenda comprises two lines of inquiry. The first develops theoretical issues relating to ....Monetary and Fiscal Policy under Imperfect Knowledge. This project lays out an agenda exploring the consequences of imperfect knowledge for macroeconomic dynamics and stabilisation policy. Learning dynamics are central to understanding aggregate fluctuations in periods during which agents have limited information about their environment, as has been the case during and after the Global Financial Crisis. The agenda comprises two lines of inquiry. The first develops theoretical issues relating to the design and implementation of monetary and fiscal policy under imperfect knowledge. The second adduces empirical evidence on the classes of possible beliefs that any macroeconomic model should account for.Read moreRead less
Supporting Entry and Growth of Australian Businesses via Tax and Transfers. This project aims to characterise the optimal tax treatment of business income for insurance and efficiency purposes. Using new data for Australia, the project expects to first identify key determinants of businesses creation, growth and exit, before and after COVID-19. In light of those determinants, the project expects to develop original macroeconomic models integrating firm dynamics into optimal taxation frameworks. ....Supporting Entry and Growth of Australian Businesses via Tax and Transfers. This project aims to characterise the optimal tax treatment of business income for insurance and efficiency purposes. Using new data for Australia, the project expects to first identify key determinants of businesses creation, growth and exit, before and after COVID-19. In light of those determinants, the project expects to develop original macroeconomic models integrating firm dynamics into optimal taxation frameworks. Expected outcomes include formulating fiscal policies that provide adequate stimulus to businesses, by balancing public insurance and income inequality. This should deliver evidence-based inputs to promote Australia's post-pandemic recovery, through the design of a fairer and more efficient business tax and transfer system.Read moreRead less
Productivity, growth and unemployment in economies with frictions. This project aims to examine decisions driving productivity, growth, and unemployment in macroeconomies with frictions. It examines how government (fiscal, monetary, and education) policies determine these decisions, and identifies the best configurations of these policies. It will construct dynamic general equilibrium models of economies to analyse the causal structure behind productivity changes, growth and unemployment. It wil ....Productivity, growth and unemployment in economies with frictions. This project aims to examine decisions driving productivity, growth, and unemployment in macroeconomies with frictions. It examines how government (fiscal, monetary, and education) policies determine these decisions, and identifies the best configurations of these policies. It will construct dynamic general equilibrium models of economies to analyse the causal structure behind productivity changes, growth and unemployment. It will conduct quantitative experiments using simulations, to estimate optimal government policy design settings. This project expects to identify policies that promote productivity, growth and employment.Read moreRead less
