Summary
Economic analysis of time constraints on decision-making in health. This project aims to determine whether and how time constraints affect decision-making. Time constraints can impair the quality of decisions in health, resulting in serious medical and financial consequences. This project will employ experimental economic methods to examine how misaligned preferences and incentives influence decision-making under time constraints.

This project aims to determine whether and how time constraints affect decision-making. Time constraints can impair the quality of decisions in health, resulting in serious medical and financial consequences. This project will employ experimental economic methods to examine how misaligned preferences and incentives influence decision-making under time constraints. The project will offer scientific evidence and accurate measurements, provide insights into interventions to align the preferences of doctors and patients, and to lower the overtreatment of patients in the health-care market. The project expects to benefit society and contribute to a more efficient healthcare system.Read moreRead less

Summary
Economic analysis of peer effects in adolescence and adulthood. Although healthier, stronger and better at reasoning than young children, adolescents' morbidity and mortality rates are double those of young children. Unintentional injury, mostly avoidable and attributed to wrong decisions, is the biggest cause of death and hospitalisation among adolescents in Australia. Peer presence is likely to be a major cause of adolescents' inferior decision-making. This project aims to use experimental eco ....Economic analysis of peer effects in adolescence and adulthood. Although healthier, stronger and better at reasoning than young children, adolescents' morbidity and mortality rates are double those of young children. Unintentional injury, mostly avoidable and attributed to wrong decisions, is the biggest cause of death and hospitalisation among adolescents in Australia. Peer presence is likely to be a major cause of adolescents' inferior decision-making. This project aims to use experimental economics methods to study how peer presence affects the parameters of the economic decision model, specifically risk tolerance, discounting, and propensity to make errors. The project aims to advance the understanding of decision-making across the lifespan, inform theoretical modelling and advise policy-makers how to reduce the risks to adolescents.Read moreRead less
Strategic Behaviour in Games. John von Neumann’s minimax solution (1928) and its generalisation to mixed-strategy Nash (1950) equilibrium are the cornerstones of modern game theory, the mathematical framework for the study of decision making when the actions of different decision makers interact. This project studies human behaviour in situations where decision makers have an incentive to be unpredictable. The proposed research will shed light on the sources of the failure of the theory in the l ....Strategic Behaviour in Games. John von Neumann’s minimax solution (1928) and its generalisation to mixed-strategy Nash (1950) equilibrium are the cornerstones of modern game theory, the mathematical framework for the study of decision making when the actions of different decision makers interact. This project studies human behaviour in situations where decision makers have an incentive to be unpredictable. The proposed research will shed light on the sources of the failure of the theory in the lab, and assesses the practical significance of the statistical tests used to evaluate laboratory data on mixed-strategy play.Read moreRead less
Neuroeconomic foundations of probability and value perception. This project aims to investigate well-known behavioural “biases” in probability and value perception through the lens of neurobiology. This project will generate new knowledge on how the value of rewards, and the likelihood of receiving them, are incorporated in the decision-making process. Using an interdisciplinary approach, this project will be of interest to researchers from several domains of social science, which focus on how a ....Neuroeconomic foundations of probability and value perception. This project aims to investigate well-known behavioural “biases” in probability and value perception through the lens of neurobiology. This project will generate new knowledge on how the value of rewards, and the likelihood of receiving them, are incorporated in the decision-making process. Using an interdisciplinary approach, this project will be of interest to researchers from several domains of social science, which focus on how and why people make their decisions and how we could improve people’s wellbeing by improving their choices. The findings will provide insights into effective, behaviour-related policy design that aims to improve peoples’ well-being.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
The economics of (mis)information in the age of social media. New media technologies allow anyone to broadcast their views, leading to a “cacophony of voices” where misinformation flourishes. Tools from information economics are tailor-made for understanding information consumption in settings with many biased news sources. We develop economic models where many sources compete to attract and influence heterogenous listeners. We then study how misinformation spreads and amplifies when consumers ....The economics of (mis)information in the age of social media. New media technologies allow anyone to broadcast their views, leading to a “cacophony of voices” where misinformation flourishes. Tools from information economics are tailor-made for understanding information consumption in settings with many biased news sources. We develop economic models where many sources compete to attract and influence heterogenous listeners. We then study how misinformation spreads and amplifies when consumers of information communicate with many others through a social network. Finally, we study how to design simple and robust rules to foster informative discourse and filter misinformation. The results will shape economic policy recommendations for regulating misinformation in media platforms and social media.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.

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.

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
