Risky behaviours

Risky behaviours are a major cause of preventable death. They include smoking, illicit and injecting drug use, excessive consumption of alcohol and prescription drugs, gambling, unsafe sex, dangerous driving practices and also poor diet and physical inactivity. In addition to premature death, such risky behaviours cause significant ill health, placing an enormous burden on health systems and place significant negative externalities on families, friends and broader communities.

In order to inform better policies to reduce harms associated with these types of risky behaviours, we seek to provide a better understanding of the drivers of risky behaviours and their trajectory over the lifecycle. In addition, we employ econometric and economic evaluation methods to evaluate the impacts of policies and interventions on risky behaviours and their subsequent harms.
