Behavioural economics blends insights from economics and psychology to explain how people make everyday decisions. Analysing the forces that drive everyone's behaviour it helps us understand what people are motivated by, our impulse purchases, why we struggle to save, and how supermarkets can manipulate what and how much we buy. Behavioural Economics is a valuable addition to Oxford University Press's Very Short Introduction series, being well-suited to an intelligent and curious reader with limited background in the area. Baddeley offers a broad range of concepts, thinkers, experiments and implications. The book made me curious: I found myself looking up more detailed explanations of key experiments as I moved across concepts and chapters. This is perhaps the biggest compliment of all.
