In this chapter, I explore some possible policy implications concerning habitual activities relating to health – such as eating and exercise – that have (for good reason) become the subject of social and policy debate. I do so from the perspective of economic theory, empirical evidence and with a focus on the implications of some recent research in behavioural economics.
I emphasize several themes. First, I outline a simple economic perspective on habitual behaviour. Although it also accords with common sense, reasonable psychology and empirical evidence, there is some tendency by social scientists and policy-makers to neglect this perspective.
