Last week, our friend, Harvard Professor John Y. Campbell, delivered the American Economic Association’s 2016 Ely Lecture, the group’s most prominent invited lecture. His topic—a central challenge for policymakers and practitioners alike—is how to make modern finance work better for consumers who lack understanding of the opportunities and risks they face.

The ultimate goal is to foster decisions consistent with economic rationality (hence his title, “Restoring Rational Choice: The Challenge of Consumer Finance”) while minimizing the costs of government intervention.
