Recent large-scale randomized experiments find that helping people form implementation intentions by asking when and where they plan to act increases one-time actions, such as vaccinations, preventative screenings and voting. We investigate the effect of a simple scalable planning intervention...

A large literature treats take-up of commitment contracts, in the form of choice-set restrictions or penalties, as a smoking gun for time-inconsistency or self-control problems (for short, "present focus"). This paper develops techniques for inspecting this assumption, presents new...

Using data from a field experiment on exercise, we analyze the relationship between imperfect memory and people's awareness of their limited self-control. We find that people overestimate past gym attendance, and that larger overestimation of past attendance is associated with (i) more...

This paper estimates social effects of incentivizing people in teams. In two field experiments featuring exogenous team formation and opportunities for repeated social interactions, we find large team effects that operate through social channels. The team compensation system induced agents to...
