This project aims to study the design of robust implementable allocation mechanisms for agents who face financial constraints. Financial constraints are important for housing markets, big business auctions and government procurement. Yet their effect on the performance of allocation policies is not well understood. The project intends to develop a general and tractable framework of allocation mechanisms that are implementable without deficits. The project will adapt this framework to the study of revenue-maximising multi-object auctions with complementarities, and to house allocation problems and related situations where efficiency and priority assignments are important considerations. The project expects to provide policy insights and implications relevant to the Australian housing market.Read moreRead less
Incomplete Information Models for Industrial Organisation. Mergers, acquisitions, and collusive conduct take place in imperfectly competitive environments where firms have incomplete information about others. Despite this, standard workhorse models for analyzing the associated competitive effects assume that firms have complete information and typically only accommodate imperfect competition on one side of the market. This project aims to remedy this deficiency by developing the economic theory ....Incomplete Information Models for Industrial Organisation. Mergers, acquisitions, and collusive conduct take place in imperfectly competitive environments where firms have incomplete information about others. Despite this, standard workhorse models for analyzing the associated competitive effects assume that firms have complete information and typically only accommodate imperfect competition on one side of the market. This project aims to remedy this deficiency by developing the economic theory and associated practical tools for the analysis of competitive effects in settings with incomplete information and market power on both sides. The project work will be presented at seminars and workshops around the globe to both academic audiences and to practitioners at competition authorities. 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
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
An economic analysis of multi-period reform programs. This project aims to use a mechanism design approach to study multi-period reform programs and their use in the transition from status quo institutions. The project intends to shed light on the difficulties of introducing efficiency enhancing long-term policies. Expected outcomes include theoretical models that incorporate adjustment costs, common values, and complicated status quo institutions into models of economic reform from a mechanism ....An economic analysis of multi-period reform programs. This project aims to use a mechanism design approach to study multi-period reform programs and their use in the transition from status quo institutions. The project intends to shed light on the difficulties of introducing efficiency enhancing long-term policies. Expected outcomes include theoretical models that incorporate adjustment costs, common values, and complicated status quo institutions into models of economic reform from a mechanism design perspective as well as optimal dynamic reform policies in the presence of these frictions, focusing attention in the trade-off between static efficiency and dynamic welfare gains. Intended benefits include insights that are wildly applicable to the provision of public infrastructure and management of public resources.Read moreRead less

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
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.

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

Besides producing significant new knowledge, the project promises to inform future innovative economic, social and cultural developments of benefit to the Australian and international community.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.

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
