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

Summary
Half a million Australian children have a speech/language disorder, tripling their changes of poor academic outcomes, limited employment options and social isolation. Current speech therapy is limited, focusing on symptoms and ignoring evidence on underlying aetiologies. By identifying and translating findings on new genes and brain pathways leading to speech and language disorders, we will transform detection, diagnosis, prognosis and genetic counselling of affected children and their families.

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
Use Of Innovative Mobile Telehealth Technology To Enable A New Service Delivery Solution For Dysphagia Management

Summary
Dysphagia, the term used to describe a swallowing difficulty, affects up to 30% of people over 65 years of age. Speech pathologists are responsible for diagnosing and managing dysphagia, however there is a shortfall between the number of clinicians available and the large number of individuals with this condition. The study aims to validate a way to assess dysphagia using telehealth, to increase access to speech pathology services particularly for patients in rural health settings.
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
Status seeking and economic behaviour. The project will look at the importance of status seeking behaviour for the health system, behavioural experiments, international growth, and labelling. The insights will be useful for optimal redistribution policies, international cooperation, and behavioural research.
Information acquisition and voting behaviour. 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.

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
Co-evolution of the host pathogen interaction between Leptosphaeria maculans and Brassica species. Brassica canola is Australia's third largest export crop, producing 13% of the world's canola oil. However, blackleg disease, caused by the fungus Leptospheria maculans leads to annual yield losses of 15%, with 100% loss associated with breakdown of resistance. International investment has provided novel genome resources for Brassica and L. maculans. Applying these resources to understand the co-ev ....Co-evolution of the host pathogen interaction between Leptosphaeria maculans and Brassica species. Brassica canola is Australia's third largest export crop, producing 13% of the world's canola oil. However, blackleg disease, caused by the fungus Leptospheria maculans leads to annual yield losses of 15%, with 100% loss associated with breakdown of resistance. International investment has provided novel genome resources for Brassica and L. maculans. Applying these resources to understand the co-evolution of this plant-fungal interaction could prevent the current boom-bust cycle of canola production in Australia. This study will also provide a model and knowledge base for applications in other species, leading to enhanced crops with increased plant protection and robust, reliable productivity.Read moreRead less
Honesty and efficiency in the provision of expert services: doctors and other experts as participants in economic experiments. Experts serve us when we see the doctor, the financial planner or the car mechanic. In all these case the expert can take advantage of his superior knowledge and sell us something we do not need. This research will inform policy makers about the underlying motives of real world experts and allow them to design better institutions.
