A new policy paper issued by the New America Foundation and authored by Michael Barr, Sendhil Mullainathan, and Eldar Shafir argues that we need to move toward “behaviorally informed financial services regulation.” By this the authors mean that financial services regulation should incorporate the insights of behavioral economics and cognitive psychology, regarding things like default rules, framing of information, and hyperbolic discounting.
This paper comes on the heels of Richard Thaler and Cass Sunstein’s book Nudge, the culmination of their work in developing what they call “libertarian paternalism”–a soft-form version of paternalism that instead of mandating outcomes, such as requiring retirements savings, sets default rules and menu choices in a way that encourages them, such as making workers opt-out of retirement savings plans, rather than opt-in.
There’s much to commend about this work (Barr et al., as well as Thaler & Sunstein), and the incorporation of behavioral economics into law has been an important development in the last decade or so of legal scholarship. I do not doubt that behaviorally informed financial services regulation would be an improvement over our current model. But I am dubious about its ultimate efficacy for three reasons.
