Nudging is being framed.

I make three points. First, the i-frame and s-frame are not helpful frameworks for thinking about behavioral public policy. Second, the authors ignore the role of politics: Policies (and the s-frame) require laws and regulations. Third, the research on retirement savings, which is all about the system, undercuts their claims.

Should Governments Invest More in Nudging?

Governments are increasingly adopting behavioral science techniques for changing individual behavior in pursuit of policy objectives. The types of "nudge" interventions that governments are now adopting alter people's decisions without coercion or significant changes to economic incentives. We calculated ratios of impact to cost for nudge interventions and for traditional policy tools, such as tax incentives and other financial inducements, and we found that nudge interventions often compare favorably with traditional interventions. We conclude that nudging is a valuable approach that should be used more often in conjunction with traditional policies, but more calculations are needed to determine the relative effectiveness of nudging.
