Naïve and Capricious: Stumbling into the Ring of Self-Control Conflict

We model self-control conflict as a stochastic struggle of an agent against a visceral influence, which impels the agent to act sub-optimally. The agent holds costly pre-commitment technology to avoid the conflict altogether and may decide whether to procure pre-commitment or to confront the visceral influence. We examine naive expectations for the strength of the visceral influence; underestimating the visceral influence may lead the agent to exaggerate the expected utility of resisting temptation, and so mistakenly forego pre-commitment. Our analysis reveals conditions under which higher willpower – and lower visceral influence – reduces welfare. We further demonstrate that lowering risk aversion could reduce welfare. The aforementioned results call into question certain policy measures aimed at helping people improve their own behavior.
