摘 要：
The literature on paternalism has devoted extensive effort to the normative question of when intervention is justified, but the positive question---whether the choice architects who hold the power to intervene actually deploy it wisely---has received far less attention. We study the supply side of paternalism in a laboratory experiment where choice architects (CAs) can restrict decision makers' (DMs) option sets across binary risky choices that vary in difficulty. We document three findings. First, CAs intervene substantially less in harder decisions---where the two options yield similar expected returns and the welfare gain from intervention is small---even though these are precisely the problems where DMs make the most errors. This pattern holds for both altruistically and spitefully motivated CAs. Second, access to a soft instrument (information disclosure) crowds out hard intervention, with the substitution effect operating even among CAs who choose to disclose. Third, a follow-up experiment reveals a systematic supply-demand mismatch: DMs are more willing to accept intervention in harder problems, the opposite of what CAs supply. A unified theoretical framework, parameterized by a CA utility function that weights DM welfare and the act of influencing, rationalizes these findings and accommodates both benevolent and spiteful types within a single model.
