This research theme offers first-hand expertise in designing, customising, and running behavioural economics experiments and randomised controlled trials (RCTs) in real-world settings. Behavioural experiments and RCTs are increasingly used in both developed and low-middle income countries (LMIC) to address concrete challenges, apply and test insights, pilot novel solutions, and rigorously evaluate policies and practices in governments, international organisations, companies, and NGOs.
Using a combination of field, lab, and online experiments, systematically linked with longitudinal and smart data (‘behavioural data linking’), the researchers in this theme analyse economic behaviour in natural and complex settings; large-scale organisations; diverse and nationally representative samples of the population; longitudinal panels; multi-sites studies and ‘mega-studies’; national registers; administrative records; epidemiological cohorts; biomarkers banks; networks of wearable devices and sensors; panels of professionals and diverse hard-to-reach samples (e.g. policy-makers, financial investors, medical doctors, patients, scientists, officers). They also assess the extent to which findings from RCTs and behavioural economics experiments generalise across different samples, settings, contexts, and domains; how robust and reproducible these findings are when systematically accounting for diverse and heterogeneous behavioural responses and for behavioural spillovers; and how they predict real-world behaviours and translate into concrete policies, applications, and practices.
