How can we get people to save more money, eat healthy foods and engage in healthy behaviours, and more generally make better choices? There has been a lot written about the fact that human beings do not process information and make decisions in an optimal fashion. This course builds on much of the fascinating work in the area of behavioural economics and allows the student to develop a hands-on approach by learning its methods and more importantly, how it can be harnessed by suitably designing contexts to “nudge” choice. In three modules, students will be able to a) explain and interpret the principles underlying decision-making and compare the nudging approach to other methods of behaviour change, b) learn how to critique, design and interpret experiments; and c) design nudges and decision-tools to help people make better decisions. Students will also witness and participate in weekly topical debates on topics like “does irrationality impact welfare?” or “Is nudging manipulative?” If you’ve been fascinated with the buzz surrounding behavioural economics but are not sure how to actually use it, this course is for you.
