Time Delay, Externalities and Attitudes Toward Taxation. Public attitudes toward a policy have a significant impact on its effectiveness. The aim of this project is to investigate the determinants of public attitudes for incentive-based institutions, particularly taxes, by highlighting the importance of considering the intertemporal properties of taxation: when costs and benefits of taxation occur at different times. This project is designed to be a controlled study of how and why public attitud ....Time Delay, Externalities and Attitudes Toward Taxation. Public attitudes toward a policy have a significant impact on its effectiveness. The aim of this project is to investigate the determinants of public attitudes for incentive-based institutions, particularly taxes, by highlighting the importance of considering the intertemporal properties of taxation: when costs and benefits of taxation occur at different times. This project is designed to be a controlled study of how and why public attitudes towards taxation are influenced by the temporal structure of the externalities that the taxes are meant to control. The anticipated goal is to inform the design of institutions that the public will accept and, more generally, improve the understanding of intertemporal decision-making in environments with delayed externalities.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
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
The Economics of Envy. Envy is persistent and universal. It may help explain why humans are relatively less hierarchical than other primate species and prone to egalitarianism. Envy may help explain the formation of political and social structures and taxation and redistribution policies. This project will examine how in-group and out-group bias, social/economic mobility, and luck versus ability exacerbate and mitigate social preference and when these factors result in destructive and/or constru ....The Economics of Envy. Envy is persistent and universal. It may help explain why humans are relatively less hierarchical than other primate species and prone to egalitarianism. Envy may help explain the formation of political and social structures and taxation and redistribution policies. This project will examine how in-group and out-group bias, social/economic mobility, and luck versus ability exacerbate and mitigate social preference and when these factors result in destructive and/or constructive envy. This investigation contributes to the understanding of envy and its behavioural manifestations. Understanding the correlates of social preferences and the resulting behaviour is important for developing policy to reduce destructive envy and encourage constructive envy. Read moreRead less
An economic study of charitable giving. This project aims to study the motivations for charitable giving and helping behaviour and how these motivations interact with external factors under different institutions.Recent data from 2015 show that charitable donations in Australia have fallen to a 30-year low. Although real GDP has increased, inequality has risen. Social norms and perceptions relating to disadvantaged people can influence donor motivations.

This project aims to study the motivations for charitable giving and helping behaviour and how these motivations interact with external factors under different institutions.Recent data from 2015 show that charitable donations in Australia have fallen to a 30-year low. Although real GDP has increased, inequality has risen. Social norms and perceptions relating to disadvantaged people can influence donor motivations. The anticipated goal is to design initiatives that influence prosocial activities such as charitable giving, redistribution, refugee intake and migrant integration, and improve understanding of the underlying mechanisms of prosocial behaviour.Read moreRead less
The rate of time preference in choice experiments: A systematic re-analysis. This project intends to re-analyse data from over 20 years of past research to understand when and why people sometimes make short-sighted choices. Time preference is a core concept in both theoretical and applied economics and a key input in public policy, yet empirical understanding of it is poor. Almost all important decisions of households, businesses and government involve benefits and costs that unfold over time. ....The rate of time preference in choice experiments: A systematic re-analysis. This project intends to re-analyse data from over 20 years of past research to understand when and why people sometimes make short-sighted choices. Time preference is a core concept in both theoretical and applied economics and a key input in public policy, yet empirical understanding of it is poor. Almost all important decisions of households, businesses and government involve benefits and costs that unfold over time. Many economists have used decision-making experiments to study how people value the future and make trade-offs over time, but these have not reached any clear consensus. This project plans to systematically re-analyse primary data using state-of-the-art estimation techniques to generate new estimates of the discount rate for each study. These will then be analysed in a meta-regression analysis to identify the factors that cause discount rates to vary between studies.Read moreRead less
