ABSTRACT
In this ¿ nal chapter I want to look at whether behavioral economics can be used by policymakers to help people make better choices. For instance, Maria might buy gym membership but then never go to the gym. Alan might not save enough for retirement. Can we change things so that they make better choices? This question raises some tricky issues, that I will get to, but has to be a major objective of behavioral economics. It allows us to apply what we know in trying to make the world a better place where people are a little bit (or a lot) happier.
