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.

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

Extending economic design to non-market settings: An experimental study of mechanism design with intention-based preferences. Mechanism design is the engineering side of economic theory, which starts with assumptions regarding human nature and builds economic systems to best maximise efficiency according to these assumptions. This project studies mechanism design in experimental settings where individuals exhibit a desire to be kind to those who have been kind to them and unkind to those who ha ....Extending economic design to non-market settings: An experimental study of mechanism design with intention-based preferences. Mechanism design is the engineering side of economic theory, which starts with assumptions regarding human nature and builds economic systems to best maximise efficiency according to these assumptions. This project studies mechanism design in experimental settings where individuals exhibit a desire to be kind to those who have been kind to them and unkind to those who have not. Such preferences are common in many non-market settings and can have dramatic effects on the efficiency of potential mechanisms. The ultimate goal of this project is to develop applied mechanisms that are robust to heterogeneity in such intention-based preferences and which can be used in bilateral exchange, contract design and many other non-market settings.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
Voter behaviour and polarisation: The role of social preferences. This project aims to investigate how peer pressure and other social concerns affect voter participation, vote choice, and political polarisation. It will marry behavioural experimental economics with political economics and make use of complementary experimental methods that will allow for the study of carefully controlled elections, followed by a large-scale real-world test of the results. Expected outcomes include improved under ....Voter behaviour and polarisation: The role of social preferences. This project aims to investigate how peer pressure and other social concerns affect voter participation, vote choice, and political polarisation. It will marry behavioural experimental economics with political economics and make use of complementary experimental methods that will allow for the study of carefully controlled elections, followed by a large-scale real-world test of the results. Expected outcomes include improved understanding of how social media and other social factors, and political institutions such as compulsory voting, distort election representation and outcomes. Major benefits include the ability to advise policies to reduce polarisation and improve political institutions to ensure they reflect true societal preferences.Read moreRead less
Integrating architectural, mathematical and computing knowledge to capture the dynamics of air in design. This research will bring together architectural, mathematical and computing knowledge to discover effective ways to design buildings and cities that are more responsive to the complex dynamics of air movement and temperature.

An earthquake shaking table to investigate soil-structure interactions: This project aims to develop Australia's most advanced earthquake shaking table. Earthquakes are a problem of great significance to Australia. Infrastructure in civil, transport, mining and energy sectors may be at an unacceptable risk of damage under earthquake loading as current design practices do not account for the interaction between infrastructure and the ground under such loading. The shaking table will simulate earthquakes and enable controlled testing of three-tonne models of foundation and soil-structure interaction systems typical of Australia's infrastructure. The discoveries made are expected to be integral to the modernisation of Australia's seismic design standards so that earthquake-induced damage and risk exposure can be minimised.Read moreRead less
Life Cycle Measures of Cost Effectiveness for 4 D CAD in Design and Construct Projects across Industry Sectors. The effective and efficient delivery of complex construction projects will be transformed by the increased application of virtual design and construction technologies, including 4D CAD.

The effective and efficient delivery of complex construction projects will be transformed by the increased application of virtual design and construction technologies, including 4D CAD. By combining a 3D computer model of a design with the time dimension of the construction schedule, 4D CAD enables risks and opportunities to be better managed during the design phase and hence avoid costly issues during construction. However this requires addition design costs which currently represent a barrier to the uptake of this transforming technology. This project will overcome this by developing a flexible framework that allows the benefits gained across the life cycle of a project through using 4D CAD to be set against the additional costs and thus make this emerging technology more attractive to industry. Significantly this research will be based on comparative cases studies across different industry sectors including civil, building, and process engineering.Read moreRead less

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
