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
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. This project concerns the development and testing of models more descriptive of actual huma ....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. 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 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
Using behavioural economic insights to overcome student procrastination. This project aims to study the relations between present-biased time preference, procrastination, and achievement at school, using economic experiments. Investment in human capital generates economic benefits for students, families, employers, and society, but its benefits are realised far into the future. Because of these immediate costs and delayed benefits, behavioural economic theory predicts that students will procrast ....Using behavioural economic insights to overcome student procrastination. This project aims to study the relations between present-biased time preference, procrastination, and achievement at school, using economic experiments. Investment in human capital generates economic benefits for students, families, employers, and society, but its benefits are realised far into the future. Because of these immediate costs and delayed benefits, behavioural economic theory predicts that students will procrastinate. This project will identify the characteristics of students at greatest risk of procrastination, evaluate practical strategies to overcome it, and examine whether it is associated with poorer outcomes. This should help schools and policy makers reduce educational inequalities, and yield long-term benefits over students’ lives.Read moreRead less
Legitimacy and representation: A comprehensive study of electoral systems and strategic voting behaviour. 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 sect ....Legitimacy and representation: A comprehensive study of electoral systems and strategic voting behaviour. 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
Heuristic-based behavioural models with an application to macroeconomics. This project will develop behavioural micro-foundations for economic models with heterogeneous agents. In these models the interaction of decision rules used by agents leads to complex phenomena at the aggregate level, for example, the cycles of bubbles and crashes. The agents switch between decision rules on the basis of past performance. However, a broad range of specifications of the rules and switching mechanisms has l ....Heuristic-based behavioural models with an application to macroeconomics. This project will develop behavioural micro-foundations for economic models with heterogeneous agents. In these models the interaction of decision rules used by agents leads to complex phenomena at the aggregate level, for example, the cycles of bubbles and crashes. The agents switch between decision rules on the basis of past performance. However, a broad range of specifications of the rules and switching mechanisms has led to many degrees of freedom in modelling. In this project, laboratory experiments with paid human subjects will be used to discipline this modelling. The resulting models will improve macroeconomic and financial policy responses to volatile market conditions.Read moreRead less
The economics of cooperative behaviour. Free-riding and rent-seeking, such as tax avoidance and nepotism, are group-undermining activities that societies including Australia continuously struggle with. The aim of this project is to develop a fuller understanding of how to protect human groups from these socially damaging group-related behaviours. Drawing on a conceptual grounding that combines ideas from across social science, the project aims to implement a suite of economic experiments to deve ....The economics of cooperative behaviour. Free-riding and rent-seeking, such as tax avoidance and nepotism, are group-undermining activities that societies including Australia continuously struggle with. The aim of this project is to develop a fuller understanding of how to protect human groups from these socially damaging group-related behaviours. Drawing on a conceptual grounding that combines ideas from across social science, the project aims to implement a suite of economic experiments to develop a view of humans' cooperative behaviour that unites several strands of economics literature and offers new insights about how institutions that counter free-riding and rent-seeking arise and are maintained.Read moreRead less
Trustworthiness and reputation in markets: empirical and experimental studies. This project studies why consumers sometimes do not tell the truth when reporting their shopping experiences. This creates a problem for markets, since other consumers rely on that information. This research will guide firms, regulators and market platforms in how to elicit honest feedback from market participants, facilitating trust in the market.
