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
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.

Summary
Stability of Multilateral Agreements and the Limits to Cooperation. This project aims to analyze the stability of multilateral agreements. This is expected to be done by building upon the cooperative approach in game theory that focuses on groups as the primary decision makers. Moving the unit of analysis from an individual to a group has the advantage of widening the applicability of game theoretic methods to social issues. Consequently, the project is expected to enhance our understanding of h ....Stability of Multilateral Agreements and the Limits to Cooperation. This project aims to analyze the stability of multilateral agreements. This is expected to be done by building upon the cooperative approach in game theory that focuses on groups as the primary decision makers. Moving the unit of analysis from an individual to a group has the advantage of widening the applicability of game theoretic methods to social issues. Consequently, the project is expected to enhance our understanding of how and why cooperation can be sustained in some of the most pressing challenges faced by the society today that require extensive international collaboration to overcome, such as environmental change, trade disputes, and arms-control.

Resilient Democracy for the 21st Century. This project will establish novel foundational theoretical frameworks for the design of democratic institutions that can withstand internal and external pressure towards autocratisation. It will develop state of the art dynamic models of information manipulation and political dynamics, and analyse large-scale online survey experiments, as well as contemporary and historical data. This combination will deliver new insights into the management of sensitive ....Resilient Democracy for the 21st Century. This project will establish novel foundational theoretical frameworks for the design of democratic institutions that can withstand internal and external pressure towards autocratisation. It will develop state of the art dynamic models of information manipulation and political dynamics, and analyse large-scale online survey experiments, as well as contemporary and historical data. This combination will deliver new insights into the management of sensitive information and how to protect democracy from information manipulation. Ultimately, the project will generate a body of theoretical and empirical evidence for the design of more effective and resilient democratic institutions for a more inclusive economic development.

Testing strategy-proofness in matching markets: an experimental study. This project seeks to test and improve matching algorithms by investigating the effect of advice on strategy-proofness. Matching algorithms are used to solve allocation problems in designed markets (eg school or house allocation problems). Many of the algorithms employed are strategy-proof: participants never gain from strategising, that is, from lying about their preferences. Strategy-proofness had been seemingly validated b ....Testing strategy-proofness in matching markets: an experimental study. This project seeks to test and improve matching algorithms by investigating the effect of advice on strategy-proofness. Matching algorithms are used to solve allocation problems in designed markets (eg school or house allocation problems). Many of the algorithms employed are strategy-proof: participants never gain from strategising, that is, from lying about their preferences. Strategy-proofness had been seemingly validated by experimental research, but new evidence suggests that participants could be prone to follow wrong advice and therefore lie. In order to improve the performance of designed markets, the project proposes to further test strategy-proofness by investigating how advice can affect truth-telling in strategy-proof algorithms and whether learning can counteract or complement the effect of advice.Read moreRead less
Market Design for the Reallocation of Land. This fellowship uses laboratory and lab-in-the-field experiments to explores how market design can be used to develop combinatorial exchanges that allow participants to exchange packages of land. Allowing for package bids can facilitate trade in situations where owning one piece of land increases the value of adjacent land and where assembling contiguous pieces of land is important. Combinatorial exchanges have the potential to increase the productivit ....Market Design for the Reallocation of Land. This fellowship uses laboratory and lab-in-the-field experiments to explores how market design can be used to develop combinatorial exchanges that allow participants to exchange packages of land. Allowing for package bids can facilitate trade in situations where owning one piece of land increases the value of adjacent land and where assembling contiguous pieces of land is important. Combinatorial exchanges have the potential to increase the productivity of agriculture land in both Australia and developing countries, encourage urban redevelopment, and help the government secure land for infrastructure and environmental protection in a cost-effective way.Read moreRead less

The objective of this project is to understand and design persuasion mechanisms. Persuasion is about conveying information, influencing beliefs and manipulating actions. Educational campaigns and media censorship regulations are examples of persuasion mechanisms. Existing techniques from the economics of persuasion only permit analysis of specific and limited settings. This project aims to apply the classical mechanism design approach in a novel way to model persuasion in rich and realistic settings, thus providing insights into real-world situations. It is anticipated that this will allow us to answer questions such as ‘Should an educational campaign target different consumers with different information?’ and ‘When should a government censor extreme media outlets?'.Read moreRead less
Decentralised assets trading, centralised clearing and systemic risk. This project aims to study the effect of regulating over-the-counter (OTC) financial markets on economic performance. The lack of transparency of OTC financial markets may have exacerbated the severity of the 2007-09 financial crisis. In response, regulators around the world decided to mandate centralised clearing of derivatives traded OTC, believing this would reduce system-wide risk.

This project aims to study the effect of regulating over-the-counter (OTC) financial markets on economic performance. The lack of transparency of OTC financial markets may have exacerbated the severity of the 2007-09 financial crisis. In response, regulators around the world decided to mandate centralised clearing of derivatives traded OTC, believing this would reduce system-wide risk. This project will study the regulatory change’s effects on market participation, volumes of trade and prices, and the behavioural effect of shifting risk from market participants to clearinghouses. It expects to suggest remedial policies clearinghouses could implement to control market participants’ risk appetite. These can help enhance future productivity and reduce unemployment in Australia.Read moreRead less
