What makes a good electoral system? How can it reflect the preference of the majority while guaranteeing representation to minorities? Should voting be voluntary or mandatory? These are very relevant questions for any democracy, but particularly so for Australia: a country which has always been at the forefront of the electoral debate, that proudly strives to represent with fairness all sectors of its very diverse society and where voting is not only a citizen's right, but also her duty. By approaching these issues in a game theoretic framework, this project proposes to investigate the strategic nature of voting through a comprehensive study of electoral systems. The project will then test our theoretical predictions through a series of laboratory experiments. Read moreRead less
Information acquisition and voting behaviour. This project aims to understand citizens’ decisions to acquire information about different policy proposals within a democracy and how such information affects their voting behaviour. Proper democracies rely on the informed participation of their citizens in the political debate and political institutions. The project intends to provide formal theories of information acquisition together with empirical evidence on how voting decisions are shaped by t ....Information acquisition and voting behaviour. This project aims to understand citizens’ decisions to acquire information about different policy proposals within a democracy and how such information affects their voting behaviour. Proper democracies rely on the informed participation of their citizens in the political debate and political institutions. The project intends to provide formal theories of information acquisition together with empirical evidence on how voting decisions are shaped by the quantity and quality of information. Understanding how citizens decide to acquire information would help devise policies to reduce polarisation and improve the quality of the political debate and the democracy.Read moreRead less
Social Network Analysis: Social Media, Peer Effects and the Environment. The aims of this proposal are to better understand the role of networks in different activities such as social media, education, crime and environment-friendly behaviour. The project expects to help inform the design and practice of policies for education and environmental authorities, police and media markets. Social networks are pervasive in Australia. The project tackles issues of criminal gangs in Australian cities, the ....Social Network Analysis: Social Media, Peer Effects and the Environment. The aims of this proposal are to better understand the role of networks in different activities such as social media, education, crime and environment-friendly behaviour. The project expects to help inform the design and practice of policies for education and environmental authorities, police and media markets. Social networks are pervasive in Australia. The project tackles issues of criminal gangs in Australian cities, the political system and environment-friendly behaviours. This project is at the frontier of work in the economics of networks, with expected outcomes to include new models and methods to better understand the impact of social networks. Benefits include clear policy recommendations to improve welfare in Australian society.Read moreRead less
Games and decisions with bounded rationality: theory and economic implications. This project will develop concepts and tools for decision making in complex environments, where it is impossible to fully characterise the possible outcomes and factors that may affect them. A central goal will be to integrate heuristic rules such as the precautionary principle with the more formal approach adopted in benefit-cost analysis.
Rank-dependent choice equilibrium. This project aims to develop and test a new statistical theory of games, Rank-Dependent Choice Equilibrium (RDCE), which has the potential to unify and improve on existing approaches where the extreme reliance on perfect decision making and perfect foresight has raised doubts about their empirical relevance. The project intends to develop the theoretical foundations of RDCE, explore its relation with various parametric approaches, and evaluate RDCE via meta stu ....Rank-dependent choice equilibrium. This project aims to develop and test a new statistical theory of games, Rank-Dependent Choice Equilibrium (RDCE), which has the potential to unify and improve on existing approaches where the extreme reliance on perfect decision making and perfect foresight has raised doubts about their empirical relevance. The project intends to develop the theoretical foundations of RDCE, explore its relation with various parametric approaches, and evaluate RDCE via meta studies and stress tests. Expected outcomes of RDCE include a paradigm shift in game theory, resulting in broader acceptance and adoption of statistical game theory and to more robust policy recommendations.Read moreRead less
Designing Efficient and Equitable Voting Mechanisms. The most commonly used method for collective decision making, majority voting, is generally not efficient as it does not allow voters to express the intensity of their preferences. In addition, majority voting suffers from the tyranny of the majority, i.e. the risk of repeatedly excluding minority groups from representation. A final downside of majority voting is its winner-take-all nature, i.e. it provides no compensation for losing voters. T ....Designing Efficient and Equitable Voting Mechanisms. The most commonly used method for collective decision making, majority voting, is generally not efficient as it does not allow voters to express the intensity of their preferences. In addition, majority voting suffers from the tyranny of the majority, i.e. the risk of repeatedly excluding minority groups from representation. A final downside of majority voting is its winner-take-all nature, i.e. it provides no compensation for losing voters. This project concerns the design of alternative mechanisms that avoid these shortcomings and robustly deliver efficient and equitable outcomes. The project develops the theory underlying these novel mechanisms, tests them in a range of environments, and delivers an implementation for practical use.

Introspection, Learning, and Equilibrium in Games: Theory and Experiment. Game theory is increasingly being used in the social sciences, but the extreme reliance on perfect decision making and perfect foresight has raised doubts about its empirical relevance. This scepticism is reinforced by laboratory evidence showing behaviour patterns that are systematically biased away from game-theoretic predictions.

Game theory is increasingly being used in the social sciences, but the extreme reliance on perfect decision making and perfect foresight has raised doubts about its empirical relevance. This scepticism is reinforced by laboratory evidence showing behaviour patterns that are systematically biased away from game-theoretic predictions. This project concerns the development and testing of models more descriptive of actual human behaviour. One aim is to deliver hybrid models able to reproduce interesting patterns of first-period play (introspection), time-series data in repeated games (learning), and systematic departures from static equilibrium. Another aim is to apply a successful hybrid to improve the design of economic and social institutions.Read moreRead less
Economics of continuous-time financial markets and endogenous pricing. This research has the potential to benefit society by improving the accuracy of pricing in securities markets. First, because the research leads to specific predictions about the interaction of prices for different type of assets, it should lead to more accurate pricing across markets, such as housing, stocks and bonds, which currently function largely independently.

First, because the research leads to specific predictions about the interaction of prices for different type of assets, it should lead to more accurate pricing across markets, such as housing, stocks and bonds, which currently function largely independently.

Summary
Black swans and unknown unknowns: financial markets and their interaction with the macroeconomy in the presence of unanticipated contingencies. Unforeseen contingencies, also called 'black swans' or 'unknown unknowns' pose serious difficulties for decisionmakers. This project will examine how financial regulation can be improved to reduce the vulnerability of the financial system and the macroeconomy to unforeseen shocks.
