Good policies for bad governments: behavioral political economy

Politicians and policymakers are prone to the same biases as private citizens. Even if politicians are rational, little suggests that they have altruistic interests. Such concerns lead us to be wary of proposals that rely on benign governments to implement interventionist policies that \\"protect us from ourselves.\\" The authors recommend paternalism that recognizes both the promise and threat of activist government. They support interventions that channel behavior without taking away consumers' ability to choose for themselves. Such \\"benign paternalism\\" can lead to very dramatic behavioral changes. But benign paternalism does not give government true authority to control our lives and does not give private agents an incentive to reject such authority through black markets and other corrosive violations of the rule of law. The authors discuss five examples of policy interventions that will generate significant welfare gains without reducing consumer liberties. They believe that all policy proposals should be viewed with healthy skepticism. No doctor would prescribe a drug that only worked in theory. Likewise, economic policies should be tested with small-scale field experiments before they are adopted.
