Recent work on collective intertemporal choice suggests that non-dictatorial social preferences are generically time inconsistent. We argue that this claim conflates time consistency with two distinct properties of preferences: stationarity and time invariance. While the conjunction of time...

A stream of intertemporal monetary payoffs X first-order (second-order) temporarily dominates another stream Y if (the area below) the cumulative payoff function of X up till any moment of time is always at least as high as that of Y; or, equivalently, any rank-dependent discounted utility...

I present a model of consumption and savings for multi-person households in which members are imperfectly altruistic and share wealth. I show that, despite having standard exponential time preferences, the household is time-inconsistent: members save too little and overspend on private...

We motivate this paper with a puzzle. When we asked subjects to give five dollars to charity today, about 30 percent agree, but when the donation would instead be paid in one week, giving increases by 50 percent. The puzzle is that received models of self-control cannot explain this...

Restrictions on alcohol sales hours or days are commonly used tools in order to reduce alcohol consumption. However, a forward-looking consumer can buy in advance, and thereby mostly undo the impact of the restriction. I study whether time inconsistent consumer preferences can provide a...
