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. 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
Threshold models in micro-econometrics with applications to empirical models of health. The aim of this project is to develop and apply new statistical approaches to endogenously identify non-linear relationships between explanatory variable(s) and the response variable in non-linear econometric models and to illustrate these with applications important to empirical health economics. Literature proliferates in linear models with non-linear effects, but in health economics non-linear models domin ....Threshold models in micro-econometrics with applications to empirical models of health. The aim of this project is to develop and apply new statistical approaches to endogenously identify non-linear relationships between explanatory variable(s) and the response variable in non-linear econometric models and to illustrate these with applications important to empirical health economics. Literature proliferates in linear models with non-linear effects, but in health economics non-linear models dominate. This project will generalise these techniques to allow for various forms of the threshold variable(s), including categorical and continuous, endogenous and exogenous, and those measured with error.Read moreRead less

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.

Summary
Behavioural foundations of economic design for an uncertain world. The aim of this project is to incorporate behavioural foundations into mechanism design to improve our understanding of economic institutions in incomplete information environments. To accomplish this goal, it considers a framework where agents have reference-dependent preferences and explores implications of this assumption for economic design.
Inductive game theory: experiential knowledge, interactions, and limited inferences in social contexts. This research project stresses the importance of limited experiences and limited inferential abilities for explaining differences observed across individuals and groups in society. The project will use inductive game theory to attack problems and conflicts between individuals and groups based on such limitations.
Epistemically feasible choice: implications for sustainable risk management. The aim of this project is to examine procedural decision principles that will yield better choices in circumstances where, because of epistemic limitations, standard decision theory provides an inadequate guide. Individuals and policy-makers must make decisions even though they cannot be fully aware of all of the relevant possibilities or fully understand consequences they have not yet experienced. Examples include ind ....Epistemically feasible choice: implications for sustainable risk management. The aim of this project is to examine procedural decision principles that will yield better choices in circumstances where, because of epistemic limitations, standard decision theory provides an inadequate guide. Individuals and policy-makers must make decisions even though they cannot be fully aware of all of the relevant possibilities or fully understand consequences they have not yet experienced. Examples include individual decisions about marriage and childbearing, public policy decisions about complex environmental problems and decisions on funding scientific research. The expected outcome of the project will be a formal model of decision theory incorporating principles of resilience, sustainability and transformative experience.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
