Since 2010, I’ve been working with Glenn W. Harrison and various teams of co-researchers sponsored by CEAR to design and analyse laboratory experiments exploring responses to risk in different groups of people. Our approach emphasises the close co-integration of economic theory, econometric models and techniques, and experimental design that allows subjects to reveal rich cross-individual variety in responses. We’ve examined risky choice patterns related to gambling, smoking addiction, financial planning and investment, the Covid-19 pandemic, and responses to cognitive tests and options to compete, among other topics.
